Learned helplessness has excellent validity as an animal model for depression, but problems in reproducibility limit its use and the high degree of stress involved in the paradigm raises ethical concerns. We therefore aimed to identify which and how many trials of the learned helplessness paradigm are necessary to distinguish between helpless and non-helpless rats. A trial-by-trial reanalysis of tests from 163 rats with congenital learned helplessness or congenital non-learned helplessness and comparison of 82 rats exposed to inescapable shock with 38 shock-controls revealed that neither the first test trials, when rats showed unspecific hyperlocomotion, nor trials of the last third of the test, when almost all animals responded quickly to the stressor, contributed to sensitivity and specificity of the test. Considering only trials 3-10 improved the classification of helpless and non-helpless rats. The refined analysis allows abbreviation of the test for learned helplessness from 15 trials to 10 trials thereby reducing pain and stress of the experimental animals without losing statistical power.
Dissociation of learned helplessness and fear conditioning in mice: a mouse model of depression.

The state of being helpless is regarded as a central aspect of depression, and therefore the learned helplessness paradigm in rodents is commonly used as an animal model of depression. The term 'learned helplessness' refers to a deficit in escaping from an aversive situation after an animal is exposed to uncontrollable stress specifically, with a control/comparison group having been exposed to an equivalent amount of controllable stress. A key feature of learned helplessness is the transferability of helplessness to different situations, a phenomenon called 'trans-situationality'. However, most studies in mice use learned helplessness protocols in which training and testing occur in the same environment and with the same type of stressor. Consequently, failures to escape may reflect conditioned fear of a particular environment, not a general change of the helpless state of an animal. For mice, there is no established learned helplessness protocol that includes the trans-situationality feature. Here we describe a simple and reliable learned helplessness protocol for mice, in which training and testing are carried out in different environments and with different types of stressors. We show that with our protocol approximately 50% of mice develop learned helplessness that is not attributable to fear conditioning.

A re-view of cognitive mediators in learned helplessness.

Tennen, H

1982-12-01

The findings of Oakes and Curtis (1982), Tennen, Drum, Gillen, and Stanton (1982), and Tennen, Gillen, and Drum (1982) provide a challenge to learned helplessness theory's focus on cognitive mediators of the helplessness phenomenon. In response to these findings, Alloy (1982) argues that these studies do not challenge helplessness theory because they do not measure expected control and because they confuse necessary and sufficient causes of learned helplessness. Silver, Wortman, and Klos (1982) contend that these studies provide an inadequate test of the model because subjects are confronted with experiences which are unlike those in their natural environment. The present article argues that by Alloy's (1982) criteria, an adequate test of the learned helplessness model has not yet been conducted. Previous studies which measured expected control have not supported the model's predictions. Moreover, if perceived response-outcome independence is a sufficient, but not a necessary cause of learned helplessness, the model loses much of its heuristic value. In response to the argument that these studies lack ecological validity, this article clarifies the distinction between experimental realism and mundane realism. While real-world studies have discovered intriguing relations between perceptions of control, attributions, and coping with illness or victimization, they have not tested predictions of the learned helplessness model.

Oliveira, Emileane C; Hunziker, Maria Helena

In this study, we investigated whether (a) animals demonstrating the learned helplessness effect during an escape contingency also show learning deficits under positive reinforcement contingencies involving stimulus control and (b) the exposure to positive reinforcement contingencies eliminates the learned helplessness effect under an escape contingency. Rats were initially exposed to controllable (C), uncontrollable (U) or no (N) shocks. After 24h, they were exposed to 60 escapable shocks delivered in a shuttlebox. In the following phase, we selected from each group the four subjects that presented the most typical group pattern: no escape learning (learned helplessness effect) in Group U and escape learning in Groups C and N. All subjects were then exposed to two phases, the (1) positive reinforcement for lever pressing under a multiple FR/Extinction schedule and (2) a re-test under negative reinforcement (escape). A fourth group (n=4) was exposed only to the positive reinforcement sessions. All subjects showed discrimination learning under multiple schedule. In the escape re-test, the learned helplessness effect was maintained for three of the animals in Group U. These results suggest that the learned helplessness effect did not extend to discriminative behavior that is positively reinforced and that the learned helplessness effect did not revert for most subjects after exposure to positive reinforcement. We discuss some theoretical implications as related to learned helplessness as an effect restricted to aversive contingencies and to the absence of reversion after positive reinforcement.

Studies of learned helplessness in honey bees (Apis mellifera ligustica).

The current study reports 2 experiments investigating learned helplessness in the honey bee (Apis mellifera ligustica). In Experiment 1, we used a traditional escape method but found the bees' activity levels too high to observe changes due to treatment conditions. The bees were not able to learn in this traditional escape procedure; thus, such procedures may be inappropriate to study learned helplessness in honey bees. In Experiment 2, we used an alternative punishment, or passive avoidance, method to investigate learned helplessness. Using a master and yoked design where bees were trained as either master or yoked and tested as either master or yoked, we found that prior training with unavoidable and inescapable shock in the yoked condition interfered with avoidance and escape behavior in the later master condition. Unlike control bees, learned helplessness bees failed to restrict their movement to the safe compartment following inescapable shock. Unlike learned helplessness studies in other animals, no decrease in general activity was observed. Furthermore, we did not observe a "freezing" response to inescapable aversive stimuli-a phenomenon, thus far, consistently observed in learned helplessness tests with other species. The bees, instead, continued to move back and forth between compartments despite punishment in the incorrect compartment. These findings suggest that, although traditional escape methods may not be suitable, honey bees display learned helplessness in passive avoidance procedures. Thus, regardless of behavioral differences from other species, honey bees can be a unique invertebrate model organism for the study of learned helplessness.

Attributional style and the generality of learned helplessness.

PubMed

Alloy, L B; Peterson, C; Abramson, L Y; Seligman, M E

1984-03-01

According to the logic of the attribution reformulation of learned helplessness, the interaction of two factors influences whether helplessness experienced in one situation will transfer to a new situation. The model predicts that people who exhibit a style of attributing negative outcomes to global factors will show helplessness deficits in new situations that are either similar or dissimilar to the original situation in which they were helpless. In contrast, people who exhibit a style of attributing negative outcomes to only specific factors will show helplessness deficits in situations that are similar, but not dissimilar, to the original situation in which they were helpless. To test these predictions, we conducted two studies in which undergraduates with either a global or specific attributional style for negative outcomes were given one of three pretreatments in the typical helplessness triadic design: controllable bursts of noise, uncontrollable bursts of noise, or no noise. In Experiment 1, students were tested for helplessness deficits in a test situation similar to the pretreatment setting, whereas in Experiment 2, they were tested in a test situation dissimilar to the pretreatment setting. The findings were consistent with predictions of the reformulated helplessness theory.
The influence of gender and the estrous cycle on learned helplessness in the rat.

Although the etiology of clinical depression is unknown, women are more likely to suffer from major depressive disorder than men. In addition, in some women, there is a clear association between depression and specific phases of the menstrual cycle. Surprisingly little research has examined gender differences and the influences of the estrous cycle in this and other animal behavioral models of clinical depression. Learned helplessness is a valid animal model of stress-induced behavioral depression in which prior exposure to inescapable stress produces deficits in escape testing. Learned helplessness was studied in rats using an inescapable tail shock stress followed by a shuttle box test to determine escape latencies. Animals with mean escape latencies of >or=20 s after shuttle-box testing are defined as learned helpless. Males and normal cycling female rats in the estrus and diestrus II phases were studied. Female rats in the diestrus II phase had significantly higher escape latencies and exhibited a more helpless behavior than female rats in the estrus phase. Male rat escape latencies were intermediate between the two female phases. These results suggest a role for gonadal hormones in the development of stress-induced behavioral depression or 'learned helplessness.'
Learned helplessness: effects of response requirement and interval between treatment and testing.

PubMed

Hunziker, M H L; Dos Santos, C V

2007-11-01

Three experiments investigated learned helplessness in rats manipulating response requirements, shock duration, and intervals between treatment and testing. In Experiment 1, rats previously exposed to uncontrollable or no shocks were tested under one of four different contingencies of negative reinforcement: FR 1 or FR 2 escape contingency for running, and FR1 escape contingency for jumping (differing for the maximum shock duration of 10s or 30s). The results showed that the uncontrollable shocks produced a clear operant learning deficit (learned helplessness effect) only when the animals were tested under the jumping FR 1 escape contingency with 10-s max shock duration. Experiment 2 isolated of the effects of uncontrollability from shock exposure per se and showed that the escape deficit observed using the FR 1 escape jumping response (10-s shock duration) was produced by the uncontrollability of shock. Experiment 3 showed that using the FR 1 jumping escape contingency in the test, the learned helplessness effect was observed one, 14 or 28 days after treatment. These results suggest that running may not be an appropriate test for learned helplessness, and that many diverging results found in the literature might be accounted for by the confounding effects of respondent and operant contingencies present when running is required of rats.

Cognitive processes are assumed to change with learned helplessness, an animal model of depression, but little is known about such deficits. Here we investigated the role of cognitive and related functions in selectively bred helpless (cLH, n = 10), non-helpless (cNLH, n = 12) and wild type (WT, n = 8) Sprague Dawley rats. The animals were exposed to an open field for 10 min on each of two test days. On the third day, an object exploration paradigm was carried out. The animals were later tested for helplessness. Both cLH and cNLH rats were more active than WTs onmore » the first day in the open field. Over trials, cNLH and WT rats lowered their activity less than cLH rats. This resistance-to-habituation co-varied with a resistance to develop helplessness. In cLH rats, higher 'anxiety' or less time spent in the center of the open field co-varied with severe helplessness. In WTs, a greater reactivity to novel objects and to a spatially relocated object predicted lower levels of helplessness. In cLH rats (n = 4-5 per group), chronic treatment with a high dose of the monoamineoxidase (MAO)-Binhibitordeprenyl (10 mg/kg; i.p.), an anti-Parkinson, nootropic and antidepressant drug, attenuated helplessness. Remarkably, helplessness reversal required the experience of repeated test trials, reminiscent of a learning process. Chronic deprenyl (10 mg/kg; i.p.) did not alter locomotion/exploration or 'anxiety' in the open field. In conclusion, helplessness may be related to altered mechanisms of reinforcement learning and working memory, and to abnormalities in MAO-A and/or MAO-B functioning.« less

The effects of the selective 5-HT(2C) receptor antagonist SB 242084 on learned helplessness in male Fischer 344 rats.

Rats exposed to an uncontrollable stressor demonstrate a constellation of behaviors such as exaggerated freezing and deficits in shuttle box escape learning. These behaviors in rats have been called learned helplessness and have been argued to model human stress-related mood disorders. Learned helplessness is thought to be caused by hyperactivation of serotonin (5-HT) neurons in the dorsal raphe nucleus (DRN) and a subsequent exaggerated release of 5-HT in DRN projection sites. Blocking 5-HT(2C) receptors in the face of an increase in serotonin can alleviate anxiety behaviors in some animal models. However, specific 5-HT receptor subtypes involved in learned helplessness remain unknown. The current experiments tested the hypothesis that 5-HT(2C) receptor activation is necessary and sufficient for the expression of learned helplessness. The selective 5-HT(2C) receptor antagonist SB 242084 (1.0 mg/kg) administered i.p. to adult male Fischer 344 rats prior to shuttle box behavioral testing, but not before stress, blocked stress-induced deficits in escape learning but had no effect on the exaggerated shock-elicited freezing. The selective 5-HT(2C) receptor agonist CP-809101 was sufficient to produce learned helplessness-like behaviors in the absence of prior stress and these effects were blocked by pretreatment with SB 242084. Results implicate the 5-HT(2C) receptor subtype in mediating the shuttle box escape deficits produced by exposure to uncontrollable stress and suggest that different postsynaptic 5-HT receptor subtypes underlie the different learned helplessness behaviors.

When cognitive exertion does not yield cognitive gain: toward an informational explanation of learned helplessness.

PubMed

Sedek, G; Kofta, M

1990-04-01

This study tested a new information-processing explanation of learned helplessness that proposes that an uncontrollable situation produces helplessness symptoms because it is a source of inconsistent, self-contradictory task information during problem-solving attempts. The flow of such information makes hypothesis-testing activity futile. Prolonged and inefficient activity of this kind leads in turn to the emergence of a state of cognitive exhaustion, with accompanying performance deficits. In 3 experiments, Ss underwent informational helplessness training (IHT): They were sequentially exposed to inconsistent task information during discrimination problems. As predicted, IHT was associated with subjective symptoms of irreducible uncertainty and resulted in (a) performance deterioration on subsequent avoidance learning, (b) heightened negative mood, and (c) subjective symptoms of cognitive exhaustion.

Differential regulation of serotonin (5HT)2A receptor mRNA and protein levels after single and repeated stress in rat brain: role in learned helplessness behavior.

2005-02-01

Stress-induced learned helplessness in animals serves as a model of behavioral depression and other stress-related disorders. Our recent report that repeated stress prolongs the duration of learned helplessness behavior in rats may be important since acute and recurrent disorders may have different responsive mechanisms. To examine the role of serotonergic (5HT) mechanisms in such behavior, we studied the expression of 5HT2A receptors in different brain areas of rats, and further investigated whether the alterations in expression of 5HT2A receptors are similar after single versus repeated stress. Rats exposed to inescapable shock once on day 1, or twice, on day 1 and day 7, were tested for escape latency on days 2 and 4, or day 14, respectively. Higher escape latencies were observed on day 2 after single, and on day 14 after repeated shock. Whereas the single-stress paradigm produced a significant decrease of 5HT2A receptor mRNA and protein expression in hippocampus of non-learned helpless and learned helpless rats as compared with tested controls, repeated stress resulted in increase in frontal cortex but decrease in hippocampus and hypothalamus of learned helpless rats only, as compared with tested control rats. These results demonstrate differential regulation of 5HT2A receptors in LH rats after single and repeated stress, which may be critical in the pathophysiology of depression/other stress-related disorders.
Learned helplessness in the rat: effect of response topography in a within-subject design.

PubMed

dos Santos, Cristiano Valerio; Gehm, Tauane; Hunziker, Maria Helena Leite

2011-02-01

Three experiments investigated learned helplessness in rats manipulating response topography within-subject and different intervals between treatment and tests among groups. In Experiment 1, rats previously exposed to inescapable shocks were tested under an escape contingency where either jumping or nose poking was required to terminate shocks; tests were run either 1, 14 or 28 days after treatment. Most rats failed to jump, as expected, but learned to nose poke, regardless of the interval between treatment and tests and order of testing. The same results were observed in male and female rats from a different laboratory (Experiment 2) and despite increased exposure to the escape contingencies using a within-subject design (Experiment 3). Furthermore, no evidence of helplessness reversal was observed, since animals failed to jump even after having learned to nose-poke in a previous test session. These results are not consistent with a learned helplessness hypothesis, which claims that shock (un)controllability is the key variable responsible for the effect. They are nonetheless consistent with the view that inescapable shocks enhance control by irrelevant features of the relationship between the environment and behavior. Copyright © 2010 Elsevier B.V.

2004-04-02

Inbred rat strains for congenital learned helplessness (cLH) and for congenital resistance to learned helplessness (cNLH) were investigated as a model to study genetic predisposition to major depression. Congenitally helpless rats respond less to sucrose under a progressive ratio schedule. This is not confounded by locomotor hypoactivity: in contrast, cLH rats show a slight hyperactivity during the first 5 min of an open field test. cLH rats acquire operant responding to sucrose as readily as cNLH rats and exhibit normal memory acquisition and retrieval in the Morris water maze, thus ruling out general learning deficits as the cause of the decreased response to sucrose. Reduced total responses and reduced breaking points for sucrose in the cLH strain argue for anhedonia, which is an analogue to loss of pleasure essential for the diagnosis of major depressive episodes, and thus confirm the validity of congenitally learned helpless rats as a model of major depression.
Strain, Sex, and Open-Field Behavior: Factors Underlying the Genetic Susceptibility to Helplessness

Padilla, Eimeira; Barrett, Douglas W.; Shumake, Jason D.; Gonzalez-Lima, F.

2009-01-01

Learned helplessness represents a failure to escape after exposure to inescapable stress and may model human psychiatric disorders related to stress. Previous work has demonstrated individual differences in susceptibility to learned helplessness. In this study, we assessed different factors associated with this susceptibility, including strain, sex, and open-field behavior. Testing of three rat strains (Holtzman, Long-Evans, and Sprague-Dawley) revealed that Holtzman rats were the most susceptible to helplessness. Holtzman rats not only had the longest escape latencies following inescapable shock, but also showed spontaneous escape deficits in the absence of prior shock when tested with a fixed-ratio 2 (FR2) running response. Moreover, when tested with fixed-ratio 1 (FR1) running—an easy response normally unaffected by helplessness training in rats—inescapable shock significantly increased the escape latencies of Holtzman rats. Within the Holtzman strain, we confirmed recent findings that females showed superior escape performance and therefore appeared more resistant to helplessness than males. However, regression and covariance analyses suggest that this sex difference may be explained by more baseline ambulatory activity among females. In addition, some indices of novelty reactivity (greater exploration of novel vs. familiar open-field) predicted subsequent helpless behavior. In conclusion, Holtzman rats, and especially male Holtzman rats, have a strong predisposition to become immobile when stressed which interferes with their ability to learn active escape responses. The Holtzman strain therefore appears to be a commercially available model for studying susceptibility to helplessness in males, and novelty-seeking may be a marker of this susceptibility.

Women are more likely than men to suffer from stress-related mental disorders, such as depression. In the present experiments, we identified sex differences in one of the most common animal models of depression, that of learned helplessness. Male and female rats were trained to escape a mild footshock each day for 7 days (controllable stress). Each rat was yoked to another rat that could not escape (uncontrollable stress), but was exposed to the same amount of shock. One day later, all stressed rats and unstressed controls were tested on a more difficult escape task in a different context. Most males exposed to uncontrollable stress did not learn to escape and were therefore helpless. In contrast, most females did learn to escape on the more difficult escape task, irrespective of whether they had been exposed to controllable or uncontrollable stress. The sex differences in helplessness behavior were not dependent on the presence of sex hormones in adulthood, because neither ovariectomy of females nor castration of males abolished them. The absence of helplessness in females was neither dependent on organizational effects of testosterone during the day of birth, because masculinized females did not express helplessness as adults. Thus, sex differences in helplessness behavior are independent of gonadal hormones in adulthood and testosterone exposure during perinatal development. Learned helplessness may not constitute a valid model for depressive behavior in women, at least as reflected by the response of female rats to operant conditioning procedures after stressful experience.
Modulating effects in learned helplessness of dyadic dominance-submission relations.

Díaz-Berciano, Cristina; de Vicente, Francisco; Fontecha, Elisa

2008-01-01

In this experiment, learned helplessness was studied from an ethological perspective by examining individual differences in social dominance and its influence on the effects of helplessness. Ninety animals were used, 30 randomly selected and 60 selected because of their clear dominance or submission. Each condition (dominant, submissive, and random) was distributed in three subgroups corresponding to the triadic design. The test consisted of an escape/avoidance task. The results showed that the animals in the uncontrollable condition performed worse than those in the controllable and no treatment conditions. Social submission and dominance reduced vulnerability of the subjects against learned helplessness. Submission had a facilitating effect on subsequent learning, independently of whether pretreatment was controllability or uncontrollability. Learned mastery was observed in the submissive condition, because submission benefited the subjects in the controllable condition in comparison with the untreated subjects, and dominance impaired the subjects in the controllable condition.

Learned helplessness in the rat: improvements in validity and reliability.

Vollmayr, B; Henn, F A

2001-08-01

Major depression has a high prevalence and a high mortality. Despite many years of research little is known about the pathophysiologic events leading to depression nor about the causative molecular mechanisms of antidepressant treatment leading to remission and prevention of relapse. Animal models of depression are urgently needed to investigate new hypotheses. The learned helplessness paradigm initially described by Overmier and Seligman [J. Comp. Physiol. Psychol. 63 (1967) 28] is the most widely studied animal model of depression. Animals are exposed to inescapable shock and subsequently tested for a deficit in acquiring an avoidance task. Despite its excellent validity concerning the construct of etiology, symptomatology and prediction of treatment response [Clin. Neurosci. 1 (1993) 152; Trends Pharmacol. Sci. 12 (1991) 131] there has been little use of the model for the investigation of recent theories on the pathogenesis of depression. This may be due to reported difficulties in reliability of the paradigm [Animal Learn. Behav. 4 (1976) 401; Pharmacol. Biochem. Behav. 36 (1990) 739]. The aim of the current study was therefore to improve parameters for inescapable shock and learned helplessness testing to minimize artifacts and random error and yield a reliable fraction of helpless animals after shock exposure. The protocol uses mild current which induces helplessness only in some of the animals thereby modeling the hypothesis of variable predisposition for depression in different subjects [Psychopharmacol. Bull. 21 (1985) 443; Neurosci. Res. 38 (200) 193]. This allows us to use animals which are not helpless after inescapable shock as a stressed control, but sensitivity, specificity and variability of test results have to be reassessed.

The purpose of this cross-sectional, descriptive study was to describe the relationships between learned helplessness and disease status, functional and social disability, and disease activity in the multiple sclerosis population. Additionally, the relationships between learned helplessness and age, disease duration, education and marital and employment status were evaluated. Self-report instruments with established validity and reliability in the multiple sclerosis population were used to collect the data. Learned helplessness was significantly positively correlated with social and functional disability. Although not significant at the .05 level, disease status and disease activity were also positively correlated with learned helplessness. Additionally, unemployed individuals were more likely to be helpless than employed individuals. Overall, the results suggest that learned helplessness is related to negative health indicators in the multiple sclerosis population. Nursing interventions to decrease or prevent learned helplessness may be appropriate in this population.

Psychosocial factors are known to impact depressive symptoms across clinical populations. Learned helplessness has the potential of affecting depressive symptoms following acute myocardial infarction (AMI), though little is known about this relationship. The purpose of this study was to examine the relationship between learned helplessness and depressive symptoms in patients following an AMI. Using a descriptive cross-sectional design, participants with a diagnosed AMI within the past 12 months were recruited. Standardized instruments and measures were used to evaluate learned helplessness and depressive symptoms. A statistically significant direct relationship was found between learned helplessness and depressive symptoms, suggesting that individuals with higher self-reported levels of learned helplessness also reported more depressive symptoms. These results indicate learned helplessness is associated with depressive symptoms in individuals following an AMI. In developing post-AMI treatment plans, health care staff should focus on psychologic points of intervention to the same extent as physiologic interventions.

Learned helplessness rats are thought to be an animal model of depression. To study the role of synapse plasticity in depression, we examined the effects of learned helplessness and antidepressant treatments on synapsin I (a marker of presynaptic terminals), growth-associated protein-43 (GAP-43; a marker of growth cones), and microtubule-associated protein-2 (MAP-2; a marker of dendrites) in the hippocampus by immunolabeling. (1) Learned helplessness rats showed significant increases in the expression of synapsin I two days after the attainment of learned helplessness, and significant decreases in the protein expression eight days after the achievement of learned helplessness. Subchronic treatment of naïve rats with imipramine or fluvoxamine significantly decreased the expression of synapsin I. (2) Learned helplessness increased the expression of GAP-43 two days and eight days after learned helplessness training. Subchronic treatment of naïve rats with fluvoxamine but not imipramine showed a tendency to decrease the expression of synapsin I. (3) Learned helplessness rats showed increased expression of MAP-2 eight days after the attainment of learned helplessness. Naïve rats subchronically treated with imipramine showed a tendency toward increased expression of MAP-2, but those treated with fluvoxamine did not. These results indicate that the neuroplasticity-related proteins synapsin I, GAP-43, and MAP-2 may play a role in the pathophysiology of depression and the mechanisms of antidepressants.
Antidepressant-like effects of alnespirone (S 20499) in the learned helplessness test in rats.

Mac Sweeney, C P; Lesourd, M; Gandon, J M

1998-03-19

The effects of the new chroman derivative, alnespirone (S 20499), which is a selective 5-HT1A receptor agonist, were investigated in an animal model of depression, the learned helplessness test. Rats previously submitted to a session of 60 inescapable electric foot shocks (learned helpless controls) exhibited a deficit in escape performance in three subsequent shuttle-box sessions. Alnespirone was administered twice daily via the oral route (2.5, 5, 10, 20 mg kg(-1) day(-1)). It was shown to protect against the elevation in escape failures caused by exposure to the uncontrollable aversive situation at 5 and 10 mg kg(-1) day(-1) p.o. (13+/-2 and 10+/-3 escape failures, respectively, vs. 9+/-2 escape failures in control rats). In addition, alnespirone had a tendency to elevate the number of intertrial crossings during the resting periods, depending on the dose and day on which the avoidance task was performed (15+/-2 intertrial crossings at the dose of 5 mg kg(-1) day(-1), vs. 5+/-2 intertrial crossings for the helpless control rats, on the second day). In comparison, imipramine (64 mg kg(-1) day(-1) p.o.) provided marked protection on all three days of the avoidance task and tended to increase the number of intertrial crossings during the resting periods on the second and the third days. It is concluded that alnespirone exerts antidepressant-like properties in the learned helplessness test in rats, in a manner similar to 8-OH-DPAT (8-hydroxy-2-(di-n-propylamino)tetralin), buspirone and ipsapirone, other 5-HT1A receptor agonists.

Long-lasting effects of new Russian psychotropic drugs Noopept and Afobazol on active avoidance conditioning and formation of learned helplessness neurosis were studied on an original experimental model in rats. Noopept eliminated the manifestations of learned helplessness after long-term (21-day) treatment by increasing the percent of trained animals. Afobazol was low effective in preventing manifestations of learned helplessness, but if used for a long time, it reduced the incidence of learned helplessness development by increasing the percent of untrained animals.

The incidence of major depression is known to be influenced by both genetic and environmental factors. In the current study, we therefore set out to investigate depressive-like behavior and its modification by environmental enrichment using rats bred for 'learned helplessness'. 45 males of congenitally helpless (cLH, n=22) and non-helpless (cNLH, n=23) rats of two different generations were used to systematically investigate differential effects of environmental enrichment on learned helpless behavior, anhedonic-like behavior (sweetened condensed milk consumption) and spontaneous behavior in the home cage. While enrichment was found to reduce learned helpless behavior in 14 weeks old, but not 28 weeks old cLH rats, it did not affect the consumption of sweetened condensed milk. Regarding the home cage behavior, no consistent changes between rats of different strains, housing conditions, and ages were observed. We could thus demonstrate that a genetic predisposition for learned helplessness may interact with environmental conditions in mediating some, but not all depressive-like symptoms in congenitally learned helpless rats. However, future efforts are needed to isolate the differential benefits of environmental factors in mediating the different depression-related symptoms. Copyright © 2013 Elsevier B.V.

The unpredictable and inescapable electric shock-induced "learned helplessness" paradigm has long been used to produce an animal model of depression to identify the molecules associated with depressive symptoms or to assess the efficacy of pharmacological treatments for depression. After exposure to unpredictable and inescapable shocks (uncontrollable stress), most of mice showed defect in escape behavior in active avoidance test (learned helplessness, LH), while others did not (non-learned helplessness, NLH). Here, we investigated whether mice with LH or NLH exhibited depressive symptoms, including anhedonia, anxiety, and despair. We found that compared with control naïve mice, both uncontrollable shocks-induced LH and NLH mice showed increased anhedonia- and anxiety- but not despair-like behaviors. Notably, mice subjected to uncontrollable shocks showed similar behaviors, irrespective of whether they also showed LH or NLH. Furthermore, since both LH and NLH mice showed only anhedonia- and anxiety- but not despair-like behaviors, this model may be generally inadequate for classic depression-like behavior assessment. In conclusion, uncontrollable electric shock induces depression-like behavior, irrespective of the state of helplessness. Copyright © 2017 Elsevier B.V. All rights reserved.

We sought to determine the prevalence of and clinical variables associated with learned helplessness, a psychologic state characterized by reduced motivation, difficulty in determining causality, and depression, in family members of patients admitted to ICUs. We conducted an observational survey study of a prospectively defined cohort of family members, spouses, and partners of patients admitted to surgical, medical, and trauma ICUs at a large academic medical center. Two validated instruments, the Learned Helplessness Scale and the Perceived Stress Scale, were used, and self-report of patient clinical characteristics and subject demographics were collected. Four hundred ninety-nine family members were assessed. Of these, 238 of 460 (51.7%) had responses consistent with a significant degree of learned helplessness. Among surrogate decision-makers, this proportion was 50% (92 of 184). Characteristics associated with significant learned helplessness included grade or high school education (OR, 3.27; 95% CI, 1.29-8.27; P = .01) and Perceived Stress Scale score > 18 (OR, 4.15; 95% CI, 2.65-6.50; P < .001). The presence of a patient advance directive or do not resuscitate (DNR) order was associated with reduced odds of significant learned helplessness (OR, 0.56; 95% CI, 0.32-0.98; P = .05). The majority of family members of patients in the ICU experience significant learned helplessness. Risk factors for learned helplessness include lower educational levels, absence of an advance directive or DNR order, and higher stress levels among family members. Significant learned helplessness in family members may have negative implications in the collaborative decision-making process.

Learned helplessness is independent of levels of brain-derived neurotrophic factor in the hippocampus

Reduced levels of brain-derived neurotrophic factor (BDNF) in the hippocampus have been implicated in human affective disorders and behavioral stress responses. The current studies examined the role of BDNF in the behavioral consequences of inescapable stress, or learned helplessness. Inescapable stress decreased BDNF mRNA and protein in the hippocampus of sedentary rats. Rats allowed voluntary access to running wheels for either 3 or 6 weeks prior to exposure to stress were protected against stress-induced reductions of hippocampal BDNF protein. The observed prevention of stress-induced deceases in BDNF, however, occurred in a time course inconsistent with the prevention of learned helplessness by wheel running, which is evident following 6 weeks, but not 3 weeks, of wheel running. BDNF suppression in physically active rats was produced by administering a single injection of the selective serotonin reuptake inhibitor fluoxetine (10 mg/kg) just prior to stress. Despite reduced levels of hippocampal BDNF mRNA following stress, physically active rats given the combination of fluoxetine and stress remained resistant against learned helplessness. Sedentary rats given both fluoxetine and stress still demonstrated typical learned helplessness behaviors. Fluoxetine by itself reduced BDNF mRNA in sedentary rats only, but did not affect freezing or escape learning 24 hours later. Finally, bilateral injections of BDNF (1 μg) into the dentate gyrus prior to stress prevented stress-induced reductions of hippocampal BDNF but did not prevent learned helplessness in sedentary rats. These data indicate that learned helplessness behaviors are independent of the presence or absence of hippocampal BDNF because blocking inescapable stress-induced BDNF suppression does not always prevent learned helplessness, and learned helplessness does not always occur in the presence of reduced BDNF. Results also suggest that the prevention of stress-induced hippocampal BDNF suppression is not necessary for the protective effect of wheel running against learned helplessness. PMID:17161541

A high comorbidity between depression and alcoholism has been reported in several studies, but the mechanisms underlying this relationship remain unknown. We tested whether learned helplessness in rats as a model for depression is associated with enhanced alcohol intake and relapse behavior. Congenital learned helplessness (cLH) and congenital non-learned helplessness (cNLH) rats were selectively bred for differences in an escape paradigm. Sucrose preference was tested at the first hour of the dark phase. In order to study an association with alcohol drinking behavior, rats underwent a free-choice procedure with access to water, and 5% and 20% alcohol solutions for 6 weeks. After acquisition of alcohol drinking behavior, the alcohol deprivation effect (ADE) was assessed. Sensitivity to the sedative-hypnotic effect of alcohol was measured by loss of the righting reflex. cLH rats showed significantly lower preference for sucrose solutions during the second half hour of the dark phase than cNLH rats. Alcohol intake of male cLH rats was not significantly different from that of male cNLH rats. In contrast, cLH female rats consumed higher amounts of alcohol than female cNLH rats. The ADE was more pronounced in female animals, although the magnitude of the ADE was similar in both cNLH and cLH female rats. The time to regain the righting reflex was significantly higher in both male and female cLH rats than in cNLH rats. In summary, these data suggest that an inborn depressive-like behavior in female rats is associated with enhanced alcohol intake.

Pharmacological and genetic evidence support antidepressant-like effects elicited by the blockade of the NOP receptor. The learned helplessness (LH) model employs uncontrollable and unpredictable electric footshocks as a stressor stimulus to induce a depressive-like phenotype that can be reversed by classical antidepressants. The present study aimed to evaluate the action of NOP receptor antagonists in helpless mice. Male Swiss mice were subjected to the three steps of the LH paradigm (i.e., (1) induction, (2) screening, and (3) test). Only helpless animals were subjected to the test session. During the test session, animals were placed in the electrified chamber and the latency to escape after the footshock and the frequency of escape failures were recorded. The effect of the following treatments administered before the test session were evaluated: nortriptyline (30 mg/kg, ip, 60 min), fluoxetine (30 mg/kg, ip, four consecutive days of treatment), and NOP antagonists SB-612111 (1-10 mg/kg, ip, 30 min) and UFP-101 (1-10 nmol, icv, 5 min). To rule out possible biases, the effects of treatments on controllable stressful and non stressful situations were assessed. In helpless mice, nortriptyline, fluoxetine, UFP-101 (3-10 nmol), and SB-612111 (3-10 mg/kg) significantly reduced escape latencies and escape failures. No effects of drug treatments were observed in mice subjected to the controllable electric footshocks and non stressful situations. Acute treatment with NOP antagonists reversed helplessness similarly to the classical antidepressants. These findings support the proposal that NOP receptor antagonists are worthy of development as innovative antidepressant drugs.

Rats treated with the anxiogenic beta-carboline, N-methyl-beta-carboline-3-carboxamide (FG-7142), failed to acquire an escape response 24 h after treatment. Administration of FG-7142 resulted in a behavioral effect equivalent to a session of inescapable tailshock in this paradigm of learned helplessness. Pretreatment of rats with the selective benzodiazepine receptor antagonist Ro15-1788 blocked the development of learned helplessness elicited by FG-7142. These findings suggest that 'anxiety' may be a major factor in the development of learned helplessness.

Evidence from in situ studies supports the role of anti-apoptotic factors in the antidepressant responses of certain psychotropics. The availability of anti-ceramidase pro-apoptocic compound (LCL385) provides an opportunity to test in vivo the relation between hippocampal apopotosis and learned helplessness. 40 Sprague-Dawley male rodents underwent an FST after a treatment with LCL385, desipramine (DMI), or placebo (SAL) over 3 days. Behavioral responses, including immobility, swimming and climbing were counted during the 6min test. Western blot labeling was used to detect anti-apoptosis in hippocampus. DMI alone was associated with reduced immobility and increased climbing whereas LCL385 alone showed a decrease in Bcl-2/beta-actin ratio. Direct modulation of Bcl-2 expression in the hippocampus is not associated with learned helplessness in stressed rats. Three-day administration of DMI and LCL385 show divergent effects on behavioral and anti-apoptotic measures.

A recent hypothesis suggests reduced hippocampal neurogenesis in depression. Here, we examined cell proliferation in the dentate gyrus and the subventricular zone of rats given repeated stress, a paradigm that prolongs learned helplessness behavior, and whether antidepressants modulate the learned helplessness-associated altered cell proliferation. Decreased cell proliferation, number of clusters, and cells/cluster were noted in the dentate gyrus, but not in the subventricular zone, of learned helplessness rats. Both fluoxetine and desipramine reversed the learned helplessness behavior and increased the cell proliferation and the number of clusters in learned helplessness rats; only fluoxetine did so significantly. Both fluoxetine and desipramine significantly increased the number of cells/cluster. Our results suggest modified hippocampal neurogenesis in prolonged depression and in the mechanism of antidepressant action.

Medial thalamic 18-FDG uptake following inescapable shock correlates with subsequent learned helpless behavior

The learned helplessness paradigm has been repeatedly shown to correlate with neurobiological aspects of depression in humans. In this model, rodents are exposed inescapable foot-shock in order to reveal susceptibility to escape deficit, defined as 'learned helplessness' (LH). Few methods are available to probe the neurobiological aspects underlying the differences in susceptibility in the living animal, thus far being limited to studies examining regional neurochemical changes with microdialysis. With the widespread implementation of small animal neuroimaging methods, including positron emission tomography (PET), it is now possible to explore the living brain on a systems level to define regional changes thatmore » may correlate with vulnerability to stress. In this study, 12 wild type Sprague-Dawley rats were exposed to 40 minutes of inescapable foot-shock followed by metabolic imaging using 2-deoxy-2[{sup 18}F]fluoro-D-glucose (18-FDG) 1 hour later. The escape test was performed on these rats 48 hours later (to accommodate radiotracer decay), where they were given the opportunity to press a lever to shut off the shock. A region of interest (ROI) analysis was used to investigate potential correlations (Pearson Regression Coefficients) between regional 18-FDG uptake following inescapable shock and subsequent learned helpless behavior (time to finish the test; number of successful lever presses within 20 seconds of shock onset). ROI analysis revealed a significant positive correlation between time to finish and 18-FDG uptake, and a negative correlation between lever presses and uptake, in the medial thalamic area (p=0.033, p=0.036). This ROI included the paraventricular thalamus, mediodorsal thalamus, and the habenula. In an effort to account for possible spillover artifact, the posterior thalamic area (including ventral medial and lateral portions) was also evaluated but did not reveal significant correlations (p=0.870, p=0.897). No other significant correlations were found in additional regions analyzed including the nucleus accumbens, caudate putamen, substantia nigra, and amygdala. These data suggest that medial thalamic 18-FDG uptake during inescapable shock may contribute to subsequent escape deficits, and are not confounded by shock effects per se, since all animals received the same treatment prior to scanning. We have previously explored 18-FDG differences following the escape test session which also showed hyperactivity in the medial thalamus of learned helpless animals compared to non-learned helpless, and included additional cortical-limbic changes. Given the neuroanatomical connections between the medial thalamus (and habenula) with the prefrontal cortex and monoaminergic brain stem, one possible speculation is that abnormal neuronal activity in these areas during stress may set in motion circuitry changes that correlate with learned helpless behavior.« less

The effects of preconditioning using mild repetitive hypobaric hypoxia (360 Torr for 2 h each of 3 days) have been studied in the learned helplessness model of depression in rats. Male Wistar rats displayed persistent depressive symptoms (depressive-like behaviour in open field, increased anxiety levels in elevated plus maze, ahedonia, elevated plasma glucocorticoids and impaired dexamethasone test) following the exposure to unpredictable and inescapable footshock in the learned helplessness paradigm. Antidepressant treatment (ludiomil, 5 mg/kg i.p.) augmented the development of the depressive state. The hypoxic preconditioning had a clear antidepressive action returning the behavioural and hormonal parameters to the control values and was equally effective in terms of our study as the antidepressant. The findings suggest hypoxic preconditioning as an effective tool for the prophylaxis of post-stress affective pathologies in humans.
Consequences of Learned Helplessness and Recognition of the State of Cognitive Exhaustion in Persons with Mild Intellectual Disability

Persons with intellectual disability are a group at risk of being exposed to overly demanding problem-solving situations, which may produce learned helplessness. The research was based on the informational model of learned helplessness. The consequences of exposure to an unsolvable task and the ability to recognize the symptoms of cognitive exhaustion were tested in 120 students with mild intellectual disability. After the exposure to the unsolvable task, persons in the experimental group obtained lower results than the control group in the escape/avoidance learning task, but a similar result was found in the divergent thinking fluency task. Also, participants in the experimental group had difficulties recognizing the symptoms of the cognitive exhaustion state. After a week’s time, the difference in escape/avoidance learning performance was still observed. The results indicate that exposure to unsolvable tasks may negatively influence the cognitive performance in persons with intellectual disability, although those persons may not identify the cognitive state related to lowered performance.

MicroRNA (miRNA) expression was measured within frontal cortex of male Holtzman rats subjected to repeated inescapable shocks at days 1 and 7, tested for learned helplessness (LH) at days 2 and 8, and sacrificed at day 15. We compared rats that did vs. did not exhibit LH, as well as rats that were placed in the apparatus and tested for avoidance but not given shocks (tested controls, TC). Non-learned helpless (NLH) rats showed a robust adaptive miRNA response to inescapable shock whereas LH rats showed a markedly blunted response. One set of 12 miRNAs showed particularly large, significant down-regulation in NLH rats relative to tested controls (mir-96, 141, 182, 183, 183*, 298, 200a, 200a*, 200b, 200b*, 200c, 429). These were encoded at a few shared polycistronic loci, suggesting that the down-regulation was coordinately controlled at the level of transcription. Most of these miRNAs are enriched in synaptic fractions. Moreover, almost all of these share 5'-seed motifs with other members of the same set, suggesting that they will hit similar or overlapping sets of target mRNAs. Finally, half of this set is predicted to hit Creb1 as a target. We also identified a core miRNA co-expression module consisting of 36 miRNAs that are highly correlated with each other across individuals of the LH group (but not in the NLH or TC groups). Thus, miRNAs participate in the alterations of gene expression networks that underlie the normal (NLH) as well as aberrant (LH) response to repeated shocks.

Altered consolidation of extinction-like inhibitory learning in genotype-specific dysfunctional coping fostered by chronic stress in mice.

Campus, P; Maiolati, M; Orsini, C; Cabib, S

2016-12-15

Genetic and stress-related factors interact to foster mental disorders, possibly through dysfunctional learning. In a previous study we reported that a temporary experience of reduced food availability increases forced swim (FS)-induced helplessness tested 14days after a first experience in mice of the standard inbred C57BL/6(B6) strain but reduces it in mice of the genetically unrelated DBA/2J (D2) strain. Because persistence of FS-induced helplessness influences adaptive coping with stress challenge and involve learning processes the present study tested whether the behavioral effects of restricted feeding involved altered consolidation of FS-related learning. First, we demonstrated that restricted feeding does not influence behavior expressed on the first FS experience, supporting a specific effect on persistence rather then development of helplessness. Second, we found that FS-induced c-fos expression in the infralimbic cortex (IL) was selectively enhanced in food-restricted (FR) B6 mice and reduced in FR D2 mice, supporting opposite alterations of consolidation processes involving this brain area. Third, we demonstrated that immediate post-FS inactivation of IL prevents 24h retention of acquired helplessness by continuously free-fed mice of both strains, indicating the requirement of a functioning IL for consolidation of FS-related learning in either mouse strain. Finally, in line with the known role of IL in consolidation of extinction memories, we found that restricted feeding selectively facilitated 24h retention of an acquired extinction in B6 mice whereas impairing it in D2 mice. These findings support the conclusion that an experience of reduced food availability strain-specifically affects persistence of newly acquired passive coping strategies by altering consolidation of extinction-like inhibitory learning.

Principles of negative reinforcement learning may play a critical role in the etiology and treatment of depression. We examined the integrity of positive reinforcement learning in congenitally helpless (cH) rats, an animal model of depression, using a random ratio schedule and a devaluation-extinction procedure. Furthermore, we tested whether an antidepressant dose of the monoamine oxidase (MAO)-B inhibitor deprenyl would reverse any deficits in positive reinforcement learning. We found that cH rats (n=9) were impaired in the acquisition of even simple operant contingencies, such as a fixed interval (FI) 20 schedule. cH rats exhibited no apparent deficits in appetite or reward sensitivity. They reacted to the devaluation of food in a manner consistent with a dose-response relationship. Reinforcer motivation as assessed by lever pressing across sessions with progressively decreasing reward probabilities was highest in congenitally non-helpless (cNH, n=10) rats as long as the reward probabilities remained relatively high. cNH compared to wild-type (n=10) rats were also more resistant to extinction across sessions. Compared to saline (n=5), deprenyl (n=5) reduced the duration of immobility of cH rats in the forced swimming test, indicative of antidepressant effects, but did not restore any deficits in the acquisition of a FI 20 schedule. We conclude that positive reinforcement learning was impaired in rats bred for helplessness, possibly due to motivational impairments but not deficits in reward sensitivity, and that deprenyl exerted antidepressant effects but did not reverse the deficits in positive reinforcement learning.

Despite the fact that women are twice as likely to develop depression as men, our understanding of depression neurobiology in female subjects is limited. We have recently reported in male rats that development of helpless behavior is associated with a severe loss of hippocampal spine synapses, which is reversed by treatment with the antidepressant desipramine. Considering that estradiol has a hippocampal synaptogenic effect similar to those of antidepressants, the presence of estradiol during the female reproductive life might influence behavioral and synaptic responses to stress and depression. With electron microscopic stereology, we analyzed hippocampal spine synapses in association with helpless behavior in ovariectomized female rats (n = 70), under different conditions of estradiol exposure. Stress induced an acute and persistent loss of hippocampal spine synapses, whereas subchronic treatment with desipramine reversed the stress-induced synaptic loss. Estradiol supplementation given either before stress or before escape testing of nonstressed animals increased the number of hippocampal spine synapses. Correlation analysis demonstrated a statistically significant negative correlation between the severity of helpless behavior and hippocampal spine synapse numbers. These findings suggest that hippocampal spine synapse remodeling might be a critical factor underlying learned helplessness and, possibly, the neurobiology of depression.

Followed by the training intervention was observed that employees' helplessness decreased. The researchers have come to the idea of investigating how safety training can reduce perceived helplessness. Thus, this research examined the effectiveness of safety training on reducing employees' helplessness with attention to the mediating role of attitude toward safety issues. The current study was an experimental study with the control group. A total of 204 (101 experimental group and 103 control group) completed safety attitude questionnaire and perceived helplessness before a safety training course including four 90-min sessions over 4 consecutive days in Esfahan Steel Company in 2012 between October and December. Only members of the experimental group participated in this course. These questionnaires, approximately 30 days later, again were run on members of both groups. Data were analyzed using descriptive indexes, t-, and F-test. RESULTS by comparing the two groups showed that safety training was effective only on individuals with perceived low helplessness (p = 0.02). In individuals with perceived high helplessness, safety training only with changing safety attitudes can reduce the perceived helplessness.

Background Numerous studies have implicated neurogenesis in the hippocampus in animal models of depression, especially those related to controllability and learned helplessness. Here, we tested the hypothesis that uncontrollable, but not controllable stress would reduce cell proliferation in the hippocampus of male and female rats, and would relate to the expression of helplessness behavior. Methods To manipulate controllability, groups of male and female rats were trained in one session (acute stress) or over seven sessions (repeated stress) to escape a footshock, while yoked controls could not escape, but were exposed to the same amount of stress. Cell proliferation was assessed with immunohistochemistry of BrdU and immunofluorescence of BrdU and NeuN. Separate groups were exposed to either controllable or uncontrollable stress and their ability to learn to escape during training on a more difficult task was used as a behavioral measure of helplessness. Results Acute stress reduced cell proliferation in males, but did not affect proliferation in the female hippocampus. When animals were given the opportunity to learn to control the stress over days, males produced more cells than the yoked males without control. Repeated training with controllable stress did not influence proliferation in females. Under all conditions, males were more likely than females to express helplessness behavior, even males that were not previously stressed. Conclusions The modulation of neurogenesis by controllability was evident in males but not in females, as was the expression of helplessness behavior, despite the fact that men are less likely than women to experience depression.

Learned helplessness: validity and reliability of depressive-like states in mice.

The learned helplessness paradigm is a depression model in which animals are exposed to unpredictable and uncontrollable stress, e.g. electroshocks, and subsequently develop coping deficits for aversive but escapable situations (J.B. Overmier, M.E. Seligman, Effects of inescapable shock upon subsequent escape and avoidance responding, J. Comp. Physiol. Psychol. 63 (1967) 28-33 ). It represents a model with good similarity to the symptoms of depression, construct, and predictive validity in rats. Despite an increased need to investigate emotional, in particular depression-like behaviors in transgenic mice, so far only a few studies have been published using the learned helplessness paradigm. One reason may be the fact that-in contrast to rats (B. Vollmayr, F.A. Henn, Learned helplessness in the rat: improvements in validity and reliability, Brain Res. Brain Res. Protoc. 8 (2001) 1-7)--there is no generally accepted learned helplessness protocol available for mice. This prompted us to develop a reliable helplessness procedure in C57BL/6N mice, to exclude possible artifacts, and to establish a protocol, which yields a consistent fraction of helpless mice following the shock exposure. Furthermore, we validated this protocol pharmacologically using the tricyclic antidepressant imipramine. Here, we present a mouse model with good face and predictive validity that can be used for transgenic, behavioral, and pharmacological studies.
Learned helplessness and learned prevalence: exploring the causal relations among perceived controllability, reward prevalence, and exploration.

PubMed

Teodorescu, Kinneret; Erev, Ido

Exposure to uncontrollable outcomes has been found to trigger learned helplessness, a state in which the agent, because of lack of exploration, fails to take advantage of regained control. Although the implications of this phenomenon have been widely studied, its underlying cause remains undetermined. One can learn not to explore because the environment is uncontrollable, because the average reinforcement for exploring is low, or because rewards for exploring are rare. In the current research, we tested a simple experimental paradigm that contrasts the predictions of these three contributors and offers a unified psychological mechanism that underlies the observed phenomena. Our results demonstrate that learned helplessness is not correlated with either the perceived controllability of one's environment or the average reward, which suggests that reward prevalence is a better predictor of exploratory behavior than the other two factors. A simple computational model in which exploration decisions were based on small samples of past experiences captured the empirical phenomena while also providing a cognitive basis for feelings of uncontrollability. © The Author(s) 2014.
Persistent inhibition of hippocampal long-term potentiation in vivo by learned helplessness stress.

2010-06-01

The persistent cognitive disruptive effects of stress have been strongly implicated in the pathophysiology of depression and post-traumatic stress disorder. Here we examined factors influencing the time course of recovery from the inhibitory effect of acute inescapable stressors on the ability to induce long-term potentiation (LTP) in the dorsal hippocampus in vivo. We tested different forms of LTP, different stressors and different inbred strains of rats. Acute elevated platform stress completely, but transiently (<3 h), inhibited induction of both NMDA receptor-dependent LTP induced by a standard high frequency (200 Hz) conditioning stimulus and an additional LTP that required voltage-dependent Ca(2+) channel activation triggered by strong (400 Hz) conditioning stimulation. In contrast, acute inescapable footshock stress, used to study learned helplessness, inhibited LTP for at least 4 weeks. Contrary to expectations, there was no clear relationship between the ability of the footshock to trigger helpless behavior, a model of stress-induced depression, and the magnitude of LTP inhibition. Moreover, LTP did not appear to be affected by genetic susceptibility to learned helplessness, a model of genetic vulnerability to depression. This long-lasting synaptic plasticity disruption may underlie persistent impairment of hippocampus-dependent cognition by excessive acute inescapable stress.

Manipulating gut microbes may improve mental health. Prebiotics are indigestible compounds that increase the growth and activity of health-promoting microorganisms, yet few studies have examined how prebiotics affect CNS function. Using an acute inescapable stressor known to produce learned helplessness behaviours such as failure to escape and exaggerated fear, we tested whether early life supplementation of a blend of two prebiotics, galactooligosaccharide (GOS) and polydextrose (PDX), and the glycoprotein lactoferrin (LAC) would attenuate behavioural and biological responses to stress later in life. Juvenile, male F344 rats were fed diets containing either GOS and PDX alone, LAC alone, or GOS, PDX and LAC. All diets altered gut bacteria, while diets containing GOS and PDX increased Lactobacillus spp. After 4 weeks, rats were exposed to inescapable stress, and either immediately killed for blood and tissues, or assessed for learned helplessness 24 h later. Diets did not attenuate stress effects on spleen weight, corticosterone and blood glucose; however, all diets differentially attenuated stress-induced learned helplessness. Notably, in situ hybridization revealed that all diets reduced stress-evoked cfos mRNA in the dorsal raphe nucleus (DRN), a structure important for learned helplessness behaviours. In addition, GOS, PDX and LAC diet attenuated stress-evoked decreases in mRNA for the 5-HT 1A autoreceptor in the DRN and increased basal BDNF mRNA within the prefrontal cortex. These data suggest early life diets containing prebiotics and/or LAC promote behavioural stress resistance and uniquely modulate gene expression in corresponding circuits. © 2016 Federation of European Neuroscience Societies and John Wiley & Sons Ltd.
Attributional processes in the learned helplessness paradigm: behavioral effects of global attributions.

PubMed

Mikulincer, M

1986-12-01

Following the learned helplessness paradigm, I assessed in this study the effects of global and specific attributions for failure on the generalization of performance deficits in a dissimilar situation. Helplessness training consisted of experience with noncontingent failures on four cognitive discrimination problems attributed to either global or specific causes. Experiment 1 found that performance in a dissimilar situation was impaired following exposure to globally attributed failure. Experiment 2 examined the behavioral effects of the interaction between stable and global attributions of failure. Exposure to unsolvable problems resulted in reduced performance in a dissimilar situation only when failure was attributed to global and stable causes. Finally, Experiment 3 found that learned helplessness deficits were a product of the interaction of global and internal attribution. Performance deficits following unsolvable problems were recorded when failure was attributed to global and internal causes. Results were discussed in terms of the reformulated learned helplessness model.

The pharmacological treatment of depression in children and adolescents is different from that of adults due to the lack of efficacy of certain antidepressants in the pediatric age group. Our current understanding of why these differences occur is very limited. To develop more effective treatments, a juvenile animal model of depression was tested to validate it as a possible model to specifically study pediatric depression. Procedures for use with juvenile rats at postnatal day (PND) 21 and 28 were adapted from the adult learned helplessness model in which, 24 h after exposure to inescapable stress, animals are unable to remove themselves from an easily escapable stressor. Rats were treated for 7 days with either the selective serotonin reuptake inhibitor escitalopram at 10 mg/kg or the tricyclic antidepressant desipramine at 3, 10, or 15 mg/kg to determine if treatment could decrease escape latency times. Escitalopram treatment was effective at decreasing escape latency times in all ages tested. Desipramine treatment did not decrease escape latency times for PND 21 rats, but did decrease times for PND 28 and adult animals. The learned helplessness model with PND 21 rats predicts the efficacy of escitalopram and the lack of efficacy of desipramine seen in the treatment of pediatric depression. These findings suggest that the use of PND 21 rats in a modified learned helplessness procedure may be a valuable model of human pediatric depression that can predict pediatric antidepressant efficacy and be used to study antidepressant mechanisms involved in pediatric depression.

Major depressive disorder is a serious psychiatric condition associated with high rates of suicide and is a leading cause of health burden worldwide. However, the underlying molecular mechanisms of major depression are still essentially unclear. In our study, a non-targeted gas chromatography-mass spectrometry-based metabolomics approach was used to investigate metabolic changes in the prefrontal cortex of the learned helplessness (LH) rat model of depression. Body-weight measurements and behavioral tests including the active escape test, sucrose preference test, forced swimming test, elevated plus-maze and open field test were used to assess changes in the behavioral spectrum after inescapable footshock stress. Rats in the stress group exhibited significant learned helpless and depression-like behaviors, while without any significant change in anxiety-like behaviors. Using multivariate and univariate statistical analysis, a total of 18 differential metabolites were identified after the footshock stress protocol. Ingenuity Pathways Analysis and MetaboAnalyst were applied for predicted pathways and biological functions analysis. "Amino Acid Metabolism, Molecule Transport, Small Molecule Biochemistry" was the most significantly altered network in the LH model. Amino acid metabolism, particularly glutamate metabolism, cysteine and methionine metabolism, arginine and proline metabolism, was significantly perturbed in the prefrontal cortex of LH rats.

In a study of the domain specificity of intellectual learned helplessness, we collected data from 376 students in 14 classrooms. We measured feelings of intellectual helplessness for mathematics and language skills, anxiety about performance in each of these domains, and general working memory. Multilevel modeling analyses found that feelings of helplessness in language skills were negatively related to grades in language but were unrelated to grades in mathematics. Similarly, feelings of helplessness in mathematics were negatively related to grades in mathematics but were unrelated to grades in language. Controlling for anxiety or working memory did not change these relationships, nor did they vary across the age of students. The results support conceptualizations in which learned helplessness has a domain specific component.

Results Stress induced an acute and persistent loss of hippocampal spine synapses, while subchronic treatment with desipramine reversed the stress-induced synaptic loss. Estradiol supplementation given either prior to stress or prior to escape testing of nonstressed animals both increased the number of hippocampal spine synapses. Correlation analysis demonstrated a statistically significant negative correlation between the severity of helpless behavior and hippocampal spine synapse numbers. Conclusions These findings suggest that hippocampal spine synapse remodeling may be a critical factor underlying learned helplessness and, possibly, the neurobiology of depression. PMID:19811775
Exercise, learned helplessness, and the stress-resistant brain.

Exercise can prevent the development of stress-related mood disorders, such as depression and anxiety. The underlying neurobiological mechanisms of this effect, however, remain unknown. Recently, researchers have used animal models to begin to elucidate the potential mechanisms underlying the protective effects of physical activity. Using the behavioral consequences of uncontrollable stress or "learned helplessness" as an animal analog of depression- and anxiety-like behaviors in rats, we are investigating factors that could be important for the antidepressant and anxiolytic properties of exercise (i.e., wheel running). The current review focuses on the following: (1) the effect of exercise on the behavioral consequences of uncontrollable stress and the implications of these effects on the specificity of the "learned helplessness" animal model; (2) the neurocircuitry of learned helplessness and the role of serotonin; and (3) exercise-associated neural adaptations and neural plasticity that may contribute to the stress-resistant brain. Identifying the mechanisms by which exercise prevents learned helplessness could shed light on the complex neurobiology of depression and anxiety and potentially lead to novel strategies for the prevention of stress-related mood disorders.

We wished to examine the relevance of the theory of learned helplessness in general, and attributional style in particular, to the understanding of depression among patients with epilepsy. Patients with lateralized temporal lobe epilepsy (TLE) (right = 73, left = 70) were administered two self-report depression inventories [Beck Depression Inventory (BDI), Center for Epidemiological Studies-Depression scale (CES-D)]. Depression scores were examined in relation to a key component of the revised theory of learned helplessness (attributional style) using the Optimism/Pessimism Scale. Attributional style was significantly associated with increased self-reported depression and remained significant when the effects of several confounding variables were controlled [age, age at onset, laterality of TLE, sex, and method variance]. The results indicate that the concept of learned helplessness in general, and attributional style in particular, are related to the genesis of depression in epilepsy. Because they are known to be related to depression in the general population, and because specific techniques for intervention and prevention are available, greater consideration of learned helplessness and attributional style in the genesis of depression in epilepsy may be worthwhile.

Through a social identity theoretical lens, this study examines how nurses' identification with their working small group, unit, or floor, nursing role (e.g., staff ER nurse, nurse practitioner), and nursing profession relate to nurses' interaction involvement, willingness to confront conflict, feelings of learned helplessness, and tenure (employment turnover) intentions. A cross-sectional survey (N = 466) was conducted at a large, quaternary care hospital system. Structural equation modeling uncovered direct and indirect effects between the five primary variables. Findings demonstrate direct relationships between nurse identity (as a latent variable) and interaction involvement, willingness to confront conflict, and tenure intentions. Feelings of learned helplessness are attenuated by increased nurse identity through interaction involvement and willingness to confront conflict. In addition, willingness to confront conflict and learned helplessness mediate the relationship between interaction involvement and nurses' tenure intentions. Theoretical extensions include indirect links between nurse identity and learned helplessness via interaction involvement and willingness to confront conflict. Implications for interpersonal communication theory development, health communication, and the nursing profession are discussed.

Major depressive disorder (MDD), one of the most common mental disorders, is a significant risk factor for suicide and causes a low quality of life for many people. However, the causes and underlying mechanism of depression remain elusive. In the current work, we investigated epigenetic regulation of BDNF in the learned helplessness-induced animal model of depression. Mice were exposed to inescapable stress and divided into learned helplessness (LH) and resilient (LH-R) groups depending on the number they failed to escape. We found that the LH group had longer immobility duration in the forced swimming test (FST) and tail suspension tests (TST), which is consistent with a depression-related phenotype. Western blotting analysis and enzyme-linked immunosorbent assay (ELISA) revealed that the LH group had lower BDNF expression than that of the LH-R group. The LH group consistently had lower BDNF mRNA levels, as detected by qPCR assay. In addition, we found BDNF exon IV was down-regulated in the LH group. Intraperitoneal injection of imipramine or histone deacetylase inhibitors (HDACi) to the LH mice for 14 consecutive days ameliorated depression-like behaviors and reversed the decrease in BDNF. The expression of HDAC5 was up-regulated in the LH mice, and a ChIP assay revealed that the level of HDAC5 binding to the promoter region of BDNF exon IV was higher than that seen in other groups. Knockdown of HDAC5 reduced depression-like behaviors in the LH mice. Taken together, these results suggest that epigenetic regulation of BDNF by HDAC5 plays an important role in the learned helplessness model of depression. Copyright © 2016 Elsevier Ltd.

Congenitally helpless (cLH) rats, a well-accepted model for depression, show reduced consumption of sweet solutions only under single-housing conditions, indicating anhedonia under stress. We investigated if anhedonic-like behaviour, measured by a reduction of sweetened-condensed milk (SCM) intake and the pleasure-attenuated startle response (PAS), could be induced by an electric foot-shock stress challenge in group-housed rats. After foot-shock stress, reduced SCM intake was observed in cLH rats compared to non-helpless (cNLH) rats. Furthermore, cLH rats also showed a decreased PAS, indicating deficient reward perception. In summary, we demonstrate that a predisposition for learned helplessness interacts with stress to trigger anhedonic-like behaviour in cLH rats. These findings further add to the validity of congenitally learned helplessness as an animal model of depression, since gene-environment interactions are considered to play a role in the etiology of this disorder.

We studied the effects of new psychotropic preparations noopept and afobazole on acquisition of the conditioned active avoidance response and development of neurosis of learned helplessness in rats. Noopept in doses of 0.05-0.10 mg/kg accelerated acquisition of conditioned active avoidance response and reduced the incidence of learned helplessness in rats. Afobazole in a dose of 5 mg/kg produced an opposite effect, which is probably related to high selective anxiolytic activity of this preparation.

Abstract Background Recent emergence of long noncoding RNAs in regulating gene expression and thereby modulating physiological functions in brain has manifested their possible role in psychiatric disorders. In this study, the roles of long noncoding RNAs in susceptibility and resiliency to develop stress-induced depression and their response to antidepressant treatment were examined. Methods Microarray-based transcriptome-wide changes in long noncoding RNAs were determined in hippocampus of male Holtzman rats who showed susceptibility (learned helplessness) or resiliency (nonlearned helplessness) to develop depression. Changes in long noncoding RNA expression were also ascertained after subchronic administration of fluoxetine to learned helplessness rats. Bioinformatic and target prediction analyses (cis- and trans-acting) and qPCR-based assays were performed to decipher the functional role of altered long noncoding RNAs. Results Group-wise comparison showed an overrepresented class of long noncoding RNAs that were uniquely associated with nonlearned helplessness or learned helplessness behavior. Chromosomal mapping within the 5-kbp flank region of the top 20 dysregulated long noncoding RNAs in the learned helplessness group showed several target genes that were regulated through cis- or trans-actions, including Zbtb20 and Zfp385b from zinc finger binding protein family. Genomic context of differentially expressed long noncoding RNAs showed an overall blunted response in the learned helplessness group regardless of the long noncoding RNA classes analyzed. Gene ontology exhibited the functional clustering for anatomical structure development, cellular architecture modulation, protein metabolism, and cellular communications. Fluoxetine treatment reversed learned helplessness-induced changes in many long noncoding RNAs and target genes. Conclusions The involvement of specific classes of long noncoding RNAs with distinctive roles in modulating target gene expression could confer the role of long noncoding RNAs in resiliency or susceptibility to develop depression with a reciprocal response to antidepressant treatment.

Addiction is considered as one of the major problems in family and community in the world. According to cognitive view, organizing the experiences determines how to behave. Due to their importance in interpretation of special situations, cognitive schemas and attributional styles have a significant role in cognitive theories. The aim of this study was to compare early maladaptive schemas and attributional styles in addicts and non-addicts to recognize their role in addiction. In this causal-comparative study, 200 addicted and non-addicted men were randomly selected. Young early maladaptive schema and attributional styles questionnaires were used. Data analysis was performed by independent t-test, Pearson correlation and regression. The study population included 81 addicted and 90 non-addicted men. There were significant differences between early maladaptive schemas and attributional styles in the two groups of addicted and non-addicted men (P < 0.001). In addition, addicts had higher levels of learned helplessness. A direct relationship was found between learned helplessness and frequency of addiction treatments (r ═ 0.234, P < 0.05). Our study showed that addicts suffer from high levels of early maladaptive schemas. They had a more pessimistic attributional style. Moreover, addicts who developed higher levels of learned helplessness were less successful in addiction treatment and more likely to use drugs again after treatment. These issues show that addiction institutions and therapists have to pay attention to cognitive factors for addiction prevention.

Is there evidence of learned helplessness in horses?

Learned helplessness is a psychological condition whereby individuals learn that they have no control over unpleasant or harmful conditions, that their actions are futile, and that they are helpless. In a series of experiments in which dogs were exposed to inescapable shocks, this lack of control subsequently interfered with the ability to learn an avoidance task. There is evidence that both neural adaptations and behavioral despair occur in response to uncontrollable aversive experiences in rodents, although this has yet to be demonstrated in other species such as horses. However, certain traditional methods of horse training and some behavioral modification techniques--it has been suggested--may involve aversive conditions over which the horse has little or no control. When training and management procedures are repeatedly unpleasant for the horse and there is no clear association between behavior and outcome, this is likely to interfere with learning and performance-in addition to compromising welfare. This article reviews published literature and anecdotal evidence to explore the possibility that the phenomenon, learned helplessness, occurs in the horse.
Learned helplessness or learned inactivity after inescapable stress? Interpretation depends on coping styles.

2002-01-01

Researches on uncontrollable events in the post-soviet states are overviewed. In our research, susceptibility to learned helplessness is studied in rats with active (KHA strain) versus passive (KLA strain) coping styles. Inescapable footshocks, but not escapable footshocks, applied to KHA rats induced escape failures, diminished locomotion and coping, reduced measures of anxiety, and resulted in dexamethasone nonsuppression of the brain-hypothalamus-pituitary-adrenal axis--all characteristic of learned helplessness. In contrast, KLA rats demonstrated the same responses upon exposure to both escapable and inescapable stresses. While learned helplessness occurred in KHA rats, it appears that KLA rats exposed to inescapable stress demonstrated learned inactivity based upon the nondifference between effects of escapable and inescapable shocks. Relationships between coping styles and social ranks are discussed. Our and other's results with genetically selected strains suggest active coping in dominant and subordinate subjects, and passive coping in subdominant animals confirm the importance of coping style and its relation to health under stress.

1. Transcranial Magnetic Stimulation (TMS) is suggested to be an effective tool in the treatment of depression. However, the methodology most suitable for clinical application remains unclear. 2. The effect of TMS was tested in a double-blind and placebo-controlled setting on 18 healthy subjects. At the same time an established learned helplessness paradigm was applied to induce dysphoria, which consisted of unsolvable anagrams. 3. Sixty 0.5 Hz stimuli were administered at an intensity of 130% of the subject's motor threshold after the subjects were exposed to the learned helplessness situation. Using a vertically positioned coil, the stimuli were applied to the right or to the left frontal cortex, or on the occipital cortex as a placebo condition. 4. Although dysphoria was successfully induced by unsolvable anagrams, TMS on either of the two frontal locations did not influence mood. This lack of effect may be due to the stimulation characteristics employed here (low TMS intensity, and low frequency). On the other hand, the findings may reflect the neurobiological difference between experimentally induced sad mood and clinical depression.
Post-stress facilitation of serotonergic, but not noradrenergic, neurotransmission in the dorsal hippocampus prevents learned helplessness development in rats.

Recent pieces of evidence suggest that the dorsal hippocampus may mediate adaptation to severe and inescapable stress, possibly by the facilitation of serotonergic and/or noradrenergic neurotransmission. Chronic social stress and high corticosteroid levels would impair this coping mechanism, predisposing animals to learned helplessness. To test the hypothesis that increasing serotonin or noradrenaline levels in the dorsal hippocampus would attenuate the development of learned helplessness (LH), rats received inescapable foot shock (IS) and were tested in a shuttle box 24 h latter. Prestressed animals showed impairment of escape responses. This effect was prevented by bilateral intrahippocampal injections of zimelidine (100 nmol/0.5 microl), a serotonin reuptake blocker, immediately after IS. This effect was not observed when zimelidine was administered before or 2 h after IS. Bilateral intrahippocampal injections of desipramine (3 or 30 nmol/0.5 microl), a noradrenaline reuptake blocker, before IS or immediately after it did not prevent LH development. Desipramine (30 nmol) enhanced LH development when injected before IS. These data suggest that poststress facilitation of hippocampal serotonergic, but not noradrenergic, neurotransmission in the dorsal hippocampus facilitates adaptation to severe inescapable stress. Antidepressant effects of noradrenaline-selective drugs seem to depend on other structures than the dorsal hippocampus.

The present study assessed different effects of action-oriented versus state-oriented styles of coping with failure on achievement-related performance and cognition. In a learned helplessness experiment, students were exposed to an academic failure situation and were then tested on a series of problem-solving tasks, either immediately after the pretreatment or after a delay of 24 hours. Performance and cognitive concomitants were measured during both experimental periods. Results demonstrated that action orientation was associated with self-immunizing cognitions during helplessness training. Action-oriented participants improved their performance level even after repeated failure feedbacks. Moreover, action-oriented students assigned to the delayed test condition responded with increased striving for success and showed performance increments, even in comparison with control subjects. In contrast, state-oriented participants developed symptoms of helplessness and showed impaired performance during failure inductions. In later tests on problem-solving tasks, state-oriented groups responded with increased fear of failure. Independent of immediate or delayed test conditions, they soon lapsed into new performance decrements.

The Wistar-Kyoto (WKY) rat is an established depression model characterized by elevated anxiety- and depression-like behavior across a variety of tests. Here we further characterized specific behavioral and functional domains relevant to depression that are altered in WKY rats. Moreover, since early-life experience potently shapes emotional behavior, we also determined whether aspects of WKYs' phenotype were modifiable by early-life factors using neonatal handling or maternal separation. We first compared WKYs' behavior to that of Sprague–Dawley (SD), Wistar, and Spontaneously Hypertensive (SHR) rats in: the open field test, elevated plus maze, novelty-suppressed feeding test, a social interaction test, and the forced swim test (FST). WKYs exhibited high baseline immobility in the FST and were the only strain to show increased immobility on FST Day 2 vs. Day 1 (an indicator of learned helplessness). WKYs also showed greater social avoidance, along with enlarged adrenal glands and hearts relative to other strains. We next tested whether neonatal handling or early-life maternal separation stress influenced WKYs' behavior. Neither manipulation affected their anxiety- and depressive-like behaviors, likely due to a strong genetic underpinning of their phenotype. Our findings indicate that WKY rats are a useful model that captures specific functional domains relevant to clinical depression including: psychomotor retardation, behavioral inhibition, learned helplessness, social withdrawal, and physiological dysfunction. WKY rats appear to be resistant to early-life manipulations (i.e., neonatal handling) that are therapeutic in other strains, and may be a useful model for the development of personalized anti-depressant therapies for treatment resistant depression.

Structural and social factors are known to play a crucial role in the pathogenesis of depression. Since animal models of depression are a major tool to gain insights into the mechanisms involved in the pathophysiology of this disease it is important not only to exploit but also to be aware of factors that may affect these models. As housing represents a fundamental external factor, which is controversially debated to affect the animals' emotionality, this study aimed to investigate the impact of different social and structural housing conditions on the development of a depressive-like syndrome in the learned helplessness paradigm. Group housing in an impoverished environment led to an increased vulnerability in the learned helplessness paradigm. Groups that were housed enriched, however, were less helpless. Furthermore impoverished conditions did not increase the vulnerability in single housed animals. Regarding emotionality in the animals, basal anxiety was reduced and the exploration was enhanced by group housing and enriched environment. These results suggest that housing conditions significantly influence the outcome of learned helplessness studies.

Learned helplessness is a maladaptive response to uncontrollable stress characterized by impaired motor escape responses, reduced motivation and learning deficits. There are important individual differences in the likelihood of becoming helpless following exposure to uncontrollable stress but little is known about the neural mechanisms underlying these individual differences. Here we used structural MRI to measure gray and white matter in individuals with chronic pain, a population at high risk for helplessness due to prolonged exposure to a poorly controlled stressor (pain). Given that self-reported helplessness is predictive of treatment outcomes in chronic pain, understanding such differences might provide valuable clinical insight. We found that the magnitude of self-reported helplessness correlated with cortical thickness in the supplementary motor area (SMA) and midcingulate cortex, regions implicated in cognitive aspects of motor behavior. We then examined the white matter connectivity of these regions and found that fractional anisotropy of connected white matter tracts along the corticospinal tract was associated with helplessness and mediated the relationship between SMA cortical thickness and helplessness. These data provide novel evidence that links individual differences in the motor output pathway with perceived helplessness over a chronic and poorly controlled stressor. © 2012 The Authors.

Behavioural studies using transgenic techniques in mice usually require extensive backcrossing to a defined background strain, e.g. to C57BL/6. In this study we investigated whether backcrossing can be replaced by using the 129SvEv strain from which the embryonic stem cells are generally obtained for gene targeting strategies to analyze e.g. depression-like behaviour. For that purpose we subjected male and female 129SvEv mice to two frequently used depression tests and compared them with commonly used C57BL/6 mice. 129SvEv and C57BL/6 mice exhibited differing profiles with regard to locomotion and pain sensitivity. However, in the learned helplessness paradigm, a procedure, which represents a valid method to detect depressive-like behaviour, 129SvEv animals develop a similar level of helplessness as C57BL/6 mice. One great advantage of the 129SvEv animals though, is the fact that in this strain even females develop helplessness, which could not be produced in C57BL/6 mice. In the tail suspension test, both genders of 129SvEv exhibited more despair behaviour than C57BL/6 animals. We therefore suggest that this strain may be utilized in the establishment of new test procedures for affective diseases, since costly and time-consuming backcrossing can be prevented, depressive-like behaviour may be analyzed effectively, and gender-specific topics could be addressed in an adequate way.

In a wide range of animals, uncontrollable stressful events can induce a condition called "learned helplessness." In mammals it is associated with low general activity, poor learning, disorders of sleep and feeding, ulcers, and reduced immune status, as well as with increased serotonin in parts of the brain. It is considered an animal model of depression in humans. Here we investigate learned helplessness in Drosophila, showing that this behavioral state consists of a cognitive and a modulatory, possibly mood-like, component. A fly, getting heated as soon as it stops walking, reliably resumes walking to escape the heat. If, in contrast, the fly is not in control of the heat, it learns that its behavior has no effect and quits responding. In this state, the fly walks slowly and takes longer and more frequent rests, as if it were "depressed." This downregulation of walking behavior is more pronounced in females than in males. Learned helplessness in Drosophila is an example of how, in a certain situation, behavior is organized according to its expected consequences. Copyright © 2013 Elsevier Ltd. All rights reserved.

Multiple roles of employed women and sense of control theories were used to explain the differences. We have found significant implications for the development of intervention programs for empowering women.
Synaptic potentiation onto habenula neurons in the learned helplessness model of depression

DOE Office of Scientific and Technical Information (OSTI.GOV)

Li, B.; Schulz, D.; Li, B

The cellular basis of depressive disorders is poorly understood. Recent studies in monkeys indicate that neurons in the lateral habenula (LHb), a nucleus that mediates communication between forebrain and midbrain structures, can increase their activity when an animal fails to receive an expected positive reward or receives a stimulus that predicts aversive conditions (that is, disappointment or anticipation of a negative outcome). LHb neurons project to, and modulate, dopamine-rich regions, such as the ventral tegmental area (VTA), that control reward-seeking behaviour and participate in depressive disorders. Here we show that in two learned helplessness models of depression, excitatory synapses ontomore » LHb neurons projecting to the VTA are potentiated. Synaptic potentiation correlates with an animal's helplessness behaviour and is due to an enhanced presynaptic release probability. Depleting transmitter release by repeated electrical stimulation of LHb afferents, using a protocol that can be effective for patients who are depressed, markedly suppresses synaptic drive onto VTA-projecting LHb neurons in brain slices and can significantly reduce learned helplessness behaviour in rats. Our results indicate that increased presynaptic action onto LHb neurons contributes to the rodent learned helplessness model of depression.« less

Our results indicate that increased presynaptic action onto LHb neurons contributes to the rodent learned helplessness model of depression.

The brain cAMP regulating system and its downstream elements play a pivotal role in the therapeutic effects of antidepressants. We previously reported the increase in activities of phosphodiesterase 4, a major phosphodiesterase isozyme hydrolyzing cAMP, in the frontal cortex and hippocampus of learned helplessness rats, an animal model for depression. The present study was undertaken to examine the combination of effects of rolipram, a phosphodiesterase 4 inhibitor, with imipramine, a typical tricyclic antidepressant, on depressive behavior in learned helplessness rats. Concurrently, cAMP-response element (CRE)-binding activity and brain-derived neurotrophic factor (BDNF) levels related to the therapeutic effects of antidepressants were determined. Repeated administration of imipramine (1.25-10 mg/kg, i.p.) or rolipram (1.25 mg/kg, i.p.) reduced the number of escape failures in learned helplessness rats. Imipramine could not completely ameliorate the escape behavior to a level similar to that of non-stressed rats even at 10 mg/kg. However, repeated coadministration of rolipram with imipramine (1.25 and 2.5 mg/kg, respectively) almost completely eliminated the escape failures in learned helplessness rats. The reduction of CRE-binding activities and BDNF levels in the frontal cortex or hippocampus in learned helplessness rats were ameliorated by treatment with imipramine or rolipram alone. CRE-binding activities and/or BDNF levels of the frontal cortex and hippocampus were significantly increased by treatment with a combination of rolipram and imipramine compared to those in imipramine-treated rats. These results indicated that coadministration of phosphodiesterase type 4 inhibitors with antidepressants may be more effective for depression therapy and suggest that elevation of the cAMP signal transduction pathway is involved in the antidepressive effects.
Effects of the beta-adrenergic blockers propranolol and acebutolol on stress-induced learned helplessness behavior of rats.

Danchev, N; Staneva-Stoytcheva, D

1995-09-01

The latency time and escape ability of rats with learned helplessness behavior were studied after 1, 6 and 14 days of oral treatment with beta-adrenergic blockers propranolol (1 and 3 mg/kg) and acebutolol (10 and 30 mg/kg). A dose-dependent significant decrease in latency time and increase in number of avoidances was established after single, 6 and 14 days propranolol treatment. The selective beta 1-blocker acebutolol did not change the escape characteristics. These results suggest a greater impact of beta 1- than beta 2-adrenergic receptors for escape performance after unescapable foot shock, i.e., learned helplessness behavior.
Experimentally-induced learned helplessness in adolescents with type 1 diabetes.

McLaughlin, Elizabeth; Lefaivre, Marie-josée; Cummings, Elizabeth

2010-05-01

To determine whether adolescents with type 1 diabetes are more at risk for learned helplessness than their healthy peers. Twenty-three adolescents with diabetes and 25 controls completed a solvable or unsolvable concept formation task. All completed pre- and post-task performance and attribution ratings, and later completed an anagram-solving task to determine if perceived helplessness on the first task would negatively impact performance on the second. Participants in the unsolvable condition solved fewer anagrams; those with diabetes did not show weaker performance than controls. Participants in the solvable condition (diabetes and controls) showed an increase in internal attributions from before the concept formation task to after. In the unsolvable condition, only participants with diabetes made more external attributions for their failure. Contrary to the only other controlled study to use this paradigm in youth with chronic illness, adolescents with diabetes were not more susceptible to learned helplessness.

2017-01-01

Embracing the conceptual framework of contemporary learning theory, this study tested the hypothesis that anticipatory fear due to a sense of ongoing threat to safety and sense of helplessness in life would be the strongest determinants of PTSD and depression in domestic violence survivors. Participants were 220 domestic violence survivors recruited consecutively from 12 shelters for women in Turkey (response rate 70%). They were assessed with the Semi-Structured Interview for Survivors of Domestic Violence, Traumatic Stress Symptom Checklist, Depression Rating Scale, and Fear and Sense of Control Scale. Survivors were exposed to 21 (SD = 6.7) physical, psychological, and sexual violence stressors over 11.3 (SD = 8.8) years. They reported high levels of peritrauma perceived distress of and lack of control over stressor events. Approximately 10 months after trauma, many feared reliving the same domestic violence events, felt helpless, feared for their life, and felt in danger. PTSD and depression rates were 48.2% and 32.7%, respectively. The strongest predictors of PTSD and depression were fear due to a sense of ongoing threat to safety and sense of helplessness in life, which explained the largest amount of variances in these psychiatric conditions. The findings support the contemporary learning theory of traumatic stress and are consistent with findings of studies involving earthquake, war, and torture survivors. They imply that trauma-focused interventions designed to overcome fear, reduce helplessness, and restore sense of control over one's life would be effective in PTSD and depression in domestic violence survivors.

H/Rouen (displaying a helpless phenotype in the tail suspension test) mice exhibiting features of depressive disorders and NH/Rouen (displaying non-helpless phenotype) mice were previously created through behavioural screening and selective breeding. Learned helplessness (LH), in which footshock stress induces a coping deficit, models some aspects of depression in rodents, but so far, fewer LH studies have been performed in mice than in rats. To study H/Rouen and NH/Rouen in the LH paradigm. When CD1 mice were submitted to footshock with various training durations and shock intensities, the most suitable parameters to induce a behavioural deficit were 0.3 mA and four training sessions. A significantly longer latency to escape shocks was found in male H/Rouen mice compared to male NH/Rouen mice. On the other hand, once shocked, NH/Rouen mice showed more severe coping deficits than H/Rouen mice. In addition, a sub-chronic treatment with fluoxetine lacked efficacy in NH/Rouen mice, whereas it improved performances in H/Rouen mice. We also found that a shock reminder at day 8, subsequent to inescapable shocks, maintained helplessness for 20 days. Finally, female H/Rouen mice responded to chronic fluoxetine administration after 10 days of treatment, while a 20-day treatment was necessary to improve the behavioural deficit in H/Rouen male mice. H/Rouen and NH/Rouen lines displayed different despair-related behaviour in the LH paradigm. Fluoxetine had beneficial effects after sub-chronic or chronic but not acute treatment of H/Rouen mice, thus providing a pharmacological validation of the protocols.

Lack of Antidepressant Effects of (2R,6R)-Hydroxynorketamine in a Rat Learned Helplessness Model: Comparison with (R)-Ketamine

Shirayama, Yukihiko

2018-01-01

Abstract Background (R)-Ketamine exhibits rapid and sustained antidepressant effects in animal models of depression. It is stereoselectively metabolized to (R)-norketamine and subsequently to (2R,6R)-hydroxynorketamine in the liver. The metabolism of ketamine to hydroxynorketamine was recently demonstrated to be essential for ketamine’s antidepressant actions. However, no study has compared the antidepressant effects of these 3 compounds in animal models of depression. Methods The effects of a single i.p. injection of (R)-ketamine, (R)-norketamine, and (2R,6R)-hydroxynorketamine in a rat learned helplessness model were examined. Results A single dose of (R)-ketamine (20 mg/kg) showed an antidepressant effect in the rat learned helplessness model. In contrast, neither (R)-norketamine (20 mg/kg) nor (2R,6R)-hydroxynorketamine (20 and 40 mg/kg) did so. Conclusions Unlike (R)-ketamine, its metabolite (2R,6R)-hydroxynorketamine did not show antidepressant actions in the rat learned helplessness model. Therefore, it is unlikely that the metabolism of ketamine to hydroxynorketamine is essential for ketamine’s antidepressant actions. PMID:29155993
Congenitally learned helpless rats show abnormalities in intracellular signaling.

2003-03-15

Affective disorders and the drugs used to treat them lead to changes in intracellular signaling. We used a genetic animal model to investigate to what extent changes in intracellular signal transduction confer a vulnerability to mood or anxiety disorders. Levels of gene expression in a selectively bred strain of rats with a high vulnerability to develop congenitally learned helplessness (cLH), a strain highly resistant to the same behavior (cNLH) and outbred Sprague-Dawley (SD) control animals were compared using quantitative reverse transcription polymerase chain reaction. Congenitally learned helpless animals had a 24%-30% reduced expression of the cyclic adenosine monophosphate response element binding protein messenger ribonucleic acid (mRNA) in the hippocampus and a 40%-41% increased level of the antiapoptotic protein bcl-2 mRNA in the prefrontal cortex compared to cNLH and SD rats. Other significant changes included changes in the expression levels of the alpha catalytic subunit of protein kinase A, glycogen synthase kinase 3beta, and protein kinase C epsilon. Congenitally learned helpless animals show evidence of altered signal transduction and regulation of apoptosis compared to cNLH and SD control animals.
Learned helplessness or expectancy-value? A psychological model for describing the experiences of different categories of unemployed people.

PubMed

García Rodríguez, Y

1997-06-01

Various studies have explored the relationships between unemployment and expectation of success, commitment to work, motivation, causal attributions, self-esteem and depression. A model is proposed that assumes the relationships between these variables are moderated by (a) whether or not the unemployed individual is seeking a first job and (b) age. It is proposed that for the unemployed who are seeking their first job (seekers) the relationships among these variables will be consistent with expectancy-value theory, but for those who have had a previous job (losers), the relationships will be more consistent with learned helplessness theory. It is further assumed that within this latter group the young losers will experience "universal helplessness" whereas the adult losers will experience "personal helplessness".

Learned helplessness behavior and cognitions were assessed in 95 kindergarten-age children during a series of impossible puzzle trials followed by a solvable puzzle trial. Latent growth curve analysis revealed reliable individual differences in the trajectories of children's affect, motivation, and self-cognitions over time. Parents' reports of negative life events, harsh/negative parenting, and warm/positive parenting were associated with their children's learned helplessness behavioral trajectories and outcomes over the course of the puzzle trials. Results support speculations about the developmental origins of depressive explanatory or attributional style in children.

Learned helplessness: unique features and translational value of a cognitive depression model.

PubMed

Vollmayr, Barbara; Gass, Peter

2013-10-01

The concept of learned helplessness defines an escape or avoidance deficit after uncontrollable stress and is regarded as a depression-like coping deficit in aversive but avoidable situations. Based on a psychological construct, it ideally complements other stress-induced or genetic animal models for major depression. Because of excellent face, construct, and predictive validity, it has contributed to the elaboration of several pathophysiological concepts and has brought forward new treatment targets. Whereas learned helplessness can be modeled not only in a broad variety of mammals, but also in fish and Drosophila, we will focus here on the use of this model in rats and mice, which are today the most common species for preclinical in vivo research in psychiatry.

2017-09-01

We examined mechanisms that contribute to the rapid antidepressant effect of ketamine in mice that is dependent on glycogen synthase kinase-3 (GSK3) inhibition. We measured serotonergic (5HT)-2C-receptor (5HTR2C) cluster microRNA (miRNA) levels in mouse hippocampus after administering an antidepressant dose of ketamine (10 mg/kg) in wild-type and GSK3 knockin mice, after GSK3 inhibition with L803-mts, and in learned helpless mice. Ketamine up-regulated cluster miRNAs 448-3p, 764-5p, 1264-3p, 1298-5p and 1912-3p (2- to 11-fold). This up-regulation was abolished in GSK3 knockin mice that express mutant constitutively active GSK3. The GSK3 specific inhibitor L803-mts was antidepressant in the learned helplessness and novelty suppressed feeding depression-like behaviours and up-regulated the 5HTR2C miRNA cluster in mouse hippocampus. After administration of the learned helplessness paradigm mice were divided into cohorts that were resilient (non-depressed) or were susceptible (depressed) to learned helplessness. The resilient, but not depressed, mice displayed increased hippocampal levels of miRNAs 448-3p and 1264-3p. Administration of an antagonist to miRNA 448-3p diminished the antidepressant effect of ketamine in the learned helplessness paradigm, indicating that up-regulation of miRNA 448-3p provides an antidepressant action. These findings identify a new outcome of GSK3 inhibition by ketamine that may contribute to antidepressant effects.
Inflammatory Th17 cells promote depression-like behavior in mice

Beurel, Eléonore; Harrington, Laurie E.; Jope, Richard S.

2012-01-01

Background Recognition of substantial immune-neural interactions is revising dogmas about their insular actions and revealing that immune-neural interactions can substantially impact CNS functions. The inflammatory cytokine interleukin-6 promotes susceptibility to depression and drives production of inflammatory T helper 17 (Th17) T cells, raising the hypothesis that in mouse models Th17 cells promote susceptibility to depression-like behaviors. Methods Behavioral characteristics were measured in male mice administered Th17 cells, CD4+ cells, or vehicle, and in RORγT+/GFP mice or male mice treated with RORγT inhibitor or anti-IL-17A antibodies. Results Mouse brain Th17 cells were elevated by learned helplessness and chronic restraint stress, two common depression-like models. Th17 cell administration promoted learned helplessness in 89% of mice in a paradigm where no vehicle-treated mice developed learned helplessness, and impaired novelty suppressed feeding and social interaction behaviors. Mice deficient in the RORγT transcription factor necessary for Th17 cell production exhibited resistance to learned helplessness, identifying modulation of RORγT as a potential intervention. Treatment with the RORγT inhibitor SR1001, or anti-IL-17A antibodies to abrogate Th17 cell function, reduced Th17-dependent learned helplessness. Conclusions These findings indicate that Th17 cells are increased in the brain during depression-like states, promote depression-like behaviors in mice, and specifically inhibiting the production or function of Th17 cells reduces vulnerability to depression-like behavior, suggesting antidepressant effects may be attained by targeting Th17 cells.

An antidepressant dose of the rapidly-acting ketamine inhibits glycogen synthase kinase-3 (GSK3) in mouse hippocampus, and this inhibition is required for the antidepressant effect of ketamine in learned helplessness depression-like behavior. Here we report that treatment with an antidepressant dose of ketamine (10mg/kg) increased expression of insulin-like growth factor 2 (IGF2) in mouse hippocampus, an effect that required ketamine-induced inhibition of GSK3. Ketamine also inhibited hippocampal GSK3 and increased expression of hippocampal IGF2 in mice when administered after the induction of learned helplessness. Treatment with the specific GSK3 inhibitor L803-mts was sufficient to up-regulate hippocampal IGF2 expression. Administration of IGF2 siRNA reduced ketamine's antidepressant effect in the learned helplessness paradigm. Mice subjected to the learned helplessness paradigm were separated into two groups, those that were resilient (non-depressed) and those that were susceptible (depressed). Non-depressed resilient mice displayed higher expression of IGF2 than susceptible mice. These results indicate that IGF2 contributes to ketamine's antidepressant effect and that IGF2 may confer resilience to depression-like behavior. Copyright © 2016 Elsevier Inc. All rights reserved.

It is known that the early environment affects the mental development of rodent and human offspring. However, it is not known specifically whether a postpartum depressive state influences the depressive state in offspring. Using learned helplessness (LH) in rats as an animal model of depression, we examined the influence of maternal postpartum LH on responses to the LH test of offspring. Dam rats were judged as LH or non-helpless (nLH) on postnatal days (PN) 2-3, and maternal behavior was recorded during PN2-14. On PN 45-46, offspring were subjected to the LH test. Plasma corticosterone (CORT) levels, hippocampal levels of glucocorticoid receptor (GR) and brain-derived neurotrophic factor (BDNF) mRNA were measured before and after the LH test in offspring. Active nursing in LH dams was significantly lower than that in nLH dams. Susceptibility to LH in the offspring of LH dams was significantly higher than in those of nLH dams, and was negatively correlated with active nursing by LH dams. The GR mRNA levels before and after the LH test were lower in the offspring of LH dams than in those of nLH dams, and the reduced basal GR mRNA and protein might have resulted in the higher CORT response after the LH test. There was no significant difference in BDNF mRNA in the offspring of LH and nLH dams. These findings suggest that early postpartum LH decreased active nursing and increased depression-like behavior in the adolescent offspring via dysfunction of the hypothalamic-pituitary-adrenal axis.

Depression is a disease with a complex etiology, that is only beginning to be studied from a genetic perspective. A selectively bred line of rats susceptible to learned helplessness, a model of depression, presents an opportunity to search for genes affecting the depressive symptoms found in the helpless model which may provide clues toward understanding the human disease. A microarray study revealed a small set of genes with altered expression in the hippocampus of the congenitally helpless rats. We selected one of these genes, a member of the γ-protocadherins for further study to determine the basis for the change in expression. Helpless animals demonstrated an increased expression primarily in CA1 neurons. Protocadherins have been implicated in synapse development and these results suggest they may play a role related to the reduced neuroplasticity observed in depression. Additionally, a number of genes linked to pathways known or suspected to be involved in depression were also detected, these will require further verification and study.

Most psychiatric and neurological diseases are exacerbated by stress. Because this may partially result from stress-induced inflammation, we examined factors involved in this stress response. After a paradigm of inescapable foot shock stress that causes learned helplessness depression-like behavior, eighteen cytokines and chemokines increased in mouse hippocampus, peaking 6 to 12 hr after stress. A 24 hr prior pre-conditioning stress accelerated the rate of stress-induced hippocampal cytokine and chemokine increases, with most reaching peak levels after 1 to 3 hr, often without altering the maximal levels. Toll-like receptor 4 (TLR4) was involved in this response because most stress-induced hippocampal cytokines and chemokines were attenuated in TLR4 knockout mice. Stress activated glycogen synthase kinase-3 (GSK3) in wild-type mouse hippocampus, but not in TLR4 knockout mice. Administration of the antidepressant fluoxetine or the GSK3 inhibitor TDZD-8 reduced the stress-induced increases of most hippocampal cytokines and chemokines. Stress increased hippocampal levels of the danger-associated molecular pattern (DAMP) protein high mobility group box 1 (HMGB1), activated the inflammatory transcription factor NF-κB, and the NLRP3 inflammasome. Knockdown of HMGB1 blocked the acceleration of cytokine and chemokine increases in the hippocampus caused by two successive stresses. Fluoxetine treatment blocked stress-induced up-regulation of HMGB1 and subsequent NF-κB activation, whereas TDZD-8 administration attenuated NF-κB activation downstream of HMGB1. To test if stress-induced cytokines and chemokines contribute to depression-like behavior, the learned helplessness model was assessed. Antagonism of TNFα modestly reduced susceptibility to learned helplessness induction, whereas TLR4 knockout mice were resistant to learned helplessness. Thus, stress-induces a broad inflammatory response in mouse hippocampus that involves TLR4, GSK3, and downstream inflammatory signaling, and these stress responses contribute to susceptibility to depression-like behavior in mice.

P2X7 Receptors Drive Spine Synapse Plasticity in the Learned Helplessness Model of Depression

2017-01-01

Abstract Background Major depressive disorder is characterized by structural and functional abnormalities of cortical and limbic brain areas, including a decrease in spine synapse number in the dentate gyrus of the hippocampus. Recent studies highlighted that both genetic and pharmacological invalidation of the purinergic P2X7 receptor (P2rx7) leads to antidepressant-like phenotype in animal experiments; however, the impact of P2rx7 on depression-related structural changes in the hippocampus is not clarified yet. Methods Effects of genetic deletion of P2rx7s on depressive-like behavior and spine synapse density in the dentate gyrus were investigated using the learned helplessness mouse model of depression. Results We demonstrate that in wild-type animals, inescapable footshocks lead to learned helplessness behavior reflected in increased latency and number of escape failures to subsequent escapable footshocks. This behavior is accompanied with downregulation of mRNA encoding P2rx7 and decrease of spine synapse density in the dentate gyrus as determined by electron microscopic stereology. In addition, a decrease in synaptopodin but not in PSD95 and NR2B/GluN2B protein level was also observed under these conditions. Whereas the absence of P2rx7 was characterized by escape deficit, no learned helpless behavior is observed in these animals. Likewise, no decrease in spine synapse number and synaptopodin protein levels was detected in response to inescapable footshocks in P2rx7-deficient animals. Conclusion Our findings suggest the endogenous activation of P2rx7s in the learned helplessness model of depression and decreased plasticity of spine synapses in P2rx7-deficient mice might explain the resistance of these animals to repeated stressful stimuli.

Recognition of substantial immune-neural interactions is revising dogmas about their insular actions and revealing that immune-neural interactions can substantially impact central nervous system functions. The inflammatory cytokine interleukin-6 promotes susceptibility to depression and drives production of inflammatory T helper 17 (Th17) T cells, raising the hypothesis that in mouse models, Th17 cells promote susceptibility to depression-like behaviors. Behavioral characteristics were measured in male mice administered Th17 cells, CD4(+) cells, or vehicle and in retinoid-related orphan receptor-γT (RORγT)(+/GFP) mice or male mice treated with RORγT inhibitor or anti-interleukin-17A antibodies. Mouse brain Th17 cells were elevated by learned helplessness and chronic restraint stress, two common depression-like models. Th17 cell administration promoted learned helplessness in 89% of mice in a paradigm where no vehicle-treated mice developed learned helplessness, and impaired novelty suppressed feeding and social interaction behaviors. Mice deficient in the RORγT transcription factor necessary for Th17 cell production exhibited resistance to learned helplessness, identifying modulation of RORγT as a potential intervention. Treatment with the RORγT inhibitor SR1001, or anti-interleukin-17A antibodies to abrogate Th17 cell function, reduced Th17-dependent learned helplessness. These findings indicate that Th17 cells are increased in the brain during depression-like states, promote depression-like behaviors in mice, and specifically inhibiting the production or function of Th17 cells reduces vulnerability to depression-like behavior, suggesting antidepressant effects may be attained by targeting Th17 cells.

Learned Helplessness at Fifty: Insights from Neuroscience

Maier, Steven F.; Seligman, Martin E. P.

2016-01-01

Learned helplessness, the failure to escape shock induced by uncontrollable aversive events, was discovered half a century ago. Seligman and Maier (1967) theorized that animals learned that outcomes were independent of their responses—that nothing they did mattered – and that this learning undermined trying to escape. The mechanism of learned helplessness is now very well-charted biologically and the original theory got it backwards. Passivity in response to shock is not learned. It is the default, unlearned response to prolonged aversive events and it is mediated by the serotonergic activity of the dorsal raphe nucleus, which in turn inhibits escape. This passivity can be overcome by learning control, with the activity of the medial prefrontal cortex, which subserves the detection of control leading to the automatic inhibition of the dorsal raphe nucleus. So animals learn that they can control aversive events, but the passive failure to learn to escape is an unlearned reaction to prolonged aversive stimulation. In addition, alterations of the ventromedial prefrontal cortex-dorsal raphe pathway can come to subserve the expectation of control. We speculate that default passivity and the compensating detection and expectation of control may have substantial implications for how to treat depression. PMID:27337390

17β Estradiol increases resilience and improves hippocampal synaptic function in helpless ovariectomized rats

Bredemann, Teruko M.; McMahon, Lori L.

2014-01-01

Summary Memory impairment is the most commonly reported cognitive symptom associated with major depressive disorder. Decreased hippocampal volume and neurogenesis in depression link hippocampal dysfunction with deficits in memory. Stress decreases hippocampal dendritic spine density and long-term potentiation (LTP) at glutamate synapses, a cellular correlate of learning and memory. However, elevated plasma levels of 17β estradiol (E2) during proestrus increase hippocampal structure and function, directly opposing the negative consequences of stress. In women, significant fluctuations in ovarian hormones likely increase vulnerability of hippocampal circuits to stress, potentially contributing to the greater incidence of depression compared to men. Using the learned helplessness model of depression and ovariectomized female rats, we investigated whether acquisition of helplessness and hippocampal synaptic dysfunction is differentially impacted by the presence or absence of plasma E2. We find that inescapable shock induces a greater incidence of helplessness in vehicle- versus E2-treated OVX rats. In the vehicle-treated group, LTP was absent at CA3-CA1 synapses in slices only from helpless rats, and CA1 spine density was decreased compared to resilient rats. In contrast, significant LTP was observed in slices from E2-treated helpless rats; importantly, spine density was not different between E2-treated helpless and resilient rats, dissociating spine density from the LTP magnitude. We also find that E2 replacement can reverse previously established helpless behavior. Thus, our results show that E2 replacement in OVX rats increases resilience and improves hippocampal plasticity, suggesting that E2 therapy may increase resilience to stress and preserve hippocampal function in women experiencing large fluctuations in plasma estrogen levels.

Cognitive-behavioural theories of helplessness/hopelessness: valid models of depression?

PubMed

Henkel, V; Bussfeld, P; Möller, H-J; Hegerl, U

2002-10-01

Helplessness and hopelessness are central aspects of cognitive-behavioural explanations for the development and persistence of depression. In this article a general overview concerning the evolution of those approaches to depression is provided. Included is a critical examination of the theories. The review of the literature suggests that those cognitive models describing helplessness/hopelessness as trait factors mediating depression do not really have a strong empirical base. The majority of those studies had been conducted in healthy or only mildly depressed subjects. Thus, there seems to be little justification for broad generalisations beyond the populations studied. It seems that some of the reported studies have not tested the underlying theories adequately (e. g. correlation had sometimes been interpreted as causation; adequate prospective longitudinal study designs had seldom been applied). Moreover, the theoretical models are not generally prepared to explain all depressive features (e. g. the possibility of a spontaneous shift in a manic episode). Despite those limitations, there is a relevant impact of the learned helplessness paradigm on preclinical research in neurobiological correlates of depressive states. Last but not least, the models are of high interest with respect to the theoretical background of important modules of cognitive-behavioural therapy and its acute and prophylactic effects.

Performance deficits following failure: learned helplessness or self-esteem protection?

PubMed

Witkowski, T; Stiensmeier-Pelster, J

1998-03-01

We report two laboratory experiments which compare two competing explanations of performance deficits following failure: one based on Seligman's learned helplessness theory (LHT), and the other, on self-esteem protection theory (SEPT). In both studies, participants (Study 1: N = 40 pupils from secondary schools in Walbrzych, Poland; Study 2: N = 45 students from the University of Bielefeld, Germany) were confronted with either success or failure in a first phase of the experiment. Then, in the second phase of the experiment the participants had to work on a set of mathematical problems (Study 1) or a set of tasks taken from Raven's Progressive Matrices (Study 2) either privately or in public. In both studies failure in the first phase causes performance deficits in the second phase only if the participants had to solve the test tasks in public. These results were interpreted in line with SEPT and as incompatible with LHT.

Some individuals are resilient, whereas others succumb to despair in repeated stressful situations. The neurobiological mechanisms underlying such divergent behavioral responses remain unclear. Here, we employed an automated method for mapping neuronal activity in search of signatures of stress responses in the entire mouse brain. We used serial two-photon tomography to detect expression of c-FosGFP - a marker of neuronal activation - in c-fosGFP transgenic mice subjected to the learned helplessness (LH) procedure, a widely used model of stress-induced depression-like phenotype in laboratory animals. We found that mice showing "helpless" behavior had an overall brain-wide reduction in the level of neuronal activation compared with mice showing "resilient" behavior, with the exception of a few brain areas, including the locus coeruleus, that were more activated in the helpless mice. In addition, the helpless mice showed a strong trend of having higher similarity in whole-brain activity profile among individuals, suggesting that helplessness is represented by a more stereotypic brain-wide activation pattern. This latter effect was confirmed in rats subjected to the LH procedure, using 2-deoxy-2[18F]fluoro-D-glucose positron emission tomography to assess neural activity. Our findings reveal distinct brain activity markings that correlate with adaptive and maladaptive behavioral responses to stress, and provide a framework for further studies investigating the contribution of specific brain regions to maladaptive stress responses.
Mesolimbic effects of the antidepressant fluoxetine in Holtzman rats, a genetic strain with increased vulnerability to stress

This is the first metabolic mapping study of the effects of fluoxetine after learned helplessness training. Antidepressants are the most commonly prescribed medications, but the regions underlying treatment effects in affectively disordered brains are poorly understood. We hypothesized the antidepressant action of fluoxetine would produce adaptations in mesolimbic regions after two weeks of treatment. We used Holtzman rats, a genetic strain showing susceptibility to novelty-evoked hyperactivity and stress-evoked helplessness, to map regional brain metabolic effects caused by fluoxetine treatment. Animals underwent learned helplessness, and subsequently immobility time was scored in the forced swim test (FST). On the next day, animals began receiving two weeks of fluoxetine (5 mg/kg/day) or vehicle and were retested in the FST at the end of drug treatment. Antidepressant behavioral effects of fluoxetine were analyzed using a ratio of immobility during pre- and post-treatment FST sessions. Brains were analyzed for regional metabolic activity using quantitative cytochrome oxidase histochemistry as in our previous study using congenitally helpless rats. Fluoxetine exerted a protective effect against FST-induced immobility behavior in Holtzman rats. Fluoxetine also caused a significant reduction in the mean regional metabolism of the nucleus accumbens shell and the ventral hippocampus as compared to vehicle-treated subjects. Additional networks affected by fluoxetine treatment included the prefrontal-cingulate cortex and brainstem nuclei linked to depression (e.g. habenula, dorsal raphe and interpeduncular nucleus). We concluded that corticolimbic regions such as the prefrontal-cingulate cortex, nucleus accumbens, ventral hippocampus and key brainstem nuclei represent important contributors to the neural network mediating fluoxetine antidepressant action.

Vicariously learned helplessness: the role of perceived dominance and prestige of a model.

Prior research has examined the relationship between various model characteristics (e.g., age, competence, similarity) and the likelihood that the observers will experience vicariously learned helplessness. However, no research in this area has investigated dominance as a relevant model characteristic. This study explored whether the vicarious acquisition of learned helplessness could be mediated by the perceived dominance of a model. Participants observed a model attempting to solve anagrams. Across participant groups, the model displayed either dominant or nondominant characteristics and was either successful or unsuccessful at solving the anagrams. The characteristics displayed by the model significantly affected observers' ratings of his dominance and prestige. After viewing the model, participants attempted to solve 40 anagrams. When the dominant model was successful, observers solved significantly more anagrams than when he was unsuccessful. This effect was not found when the model was nondominant.

Glutamatergic and γ-aminobutyric acid (GABA)ergic abnormalities have recently been proposed to contribute to depression. The learned helplessness (LH) paradigm produces a reliable animal model of depression that expresses a deficit in escape behavior (LH model); an alternative phenotype that does not exhibit LH is a model of resilience to depression (non-LH model). We measured the contents of amino acids in the brain to investigate the mechanisms involved in the pathology of depression. LH and non-LH models were subjected to inescapable electric footshocks at random intervals following a conditioned avoidance test to determine acquirement of predicted escape deficits. Tissue amino acid contents in eight brain regions were measured via high-performance liquid chromatography. The non-LH model showed increased GABA levels in the dentate gyrus and nucleus accumbens and increased glutamine levels in the dentate gyrus and the orbitofrontal cortex. The LH model had reduced glutamine levels in the medial prefrontal cortex. Changes in the ratios of GABA, glutamine, and glutamate were detected in the non-LH model, but not in the LH model. Reductions in threonine levels occurred in the medial prefrontal cortex in both models, whereas elevated alanine levels were detected in the medial prefrontal cortex in non-LH animals. The present study demonstrates region-specific compensatory elevations in GABA levels in the dentate gyrus and nucleus accumbens of non-LH animals, supporting the implication of the GABAergic system in the recovery of depression.

Fatigue and depression are common symptoms after stroke. Animal models of poststroke fatigue (PSF) and poststroke depression (PSD) would facilitate the study of these symptoms. Spontaneous locomotor activity is as an objective measure of fatigue and learned helplessness an accepted correlate of depression. We used different rat strains to evaluate stroke-induced changes in behavior in hopes that interstrain differences would provide insights into the biological basis of these symptoms. Male Lewis, Wistar, and Sprague-Dawley (SD) rats underwent experimental stroke. Spontaneous activity was assessed continually after stroke (for up to 50 days). In a subset of animals, the forced swim test was performed prior to and 1 month after stroke to assess learned helplessness; blood was obtained at sacrifice for cytokine assay. Stroke induced strain-related differences in activity; Lewis rats increased spontaneous activity during the dark cycle, while Wistar and SD rats increased activity during the light cycle. The velocity of movement decreased during the dark cycle in Wistar and SD rats and during the light cycle in Lewis rats. Stroke also led to an increase in learned helplessness in Lewis rats. In summary, different patterns of behaviors emerge in different rat strains after stroke. Lewis rats displayed behavior consistent with depression but not fatigue, while Wistar and SD rats displayed behavior consistent with fatigue but not depression. These data argue that PSF and PSD are different biological constructs and suggest that analysis of strain-related differences may provide insight into symptom pathophysiology.

Exposure of rats to unpredictable, inescapable stress results in two distinct behaviors during subsequent escape testing. One behavior, suggestive of lack of stress resilience, is prolonged escape latency compared to non-stressed rats and is labeled learned helplessness (LH). The other behavior suggestive of stress resilience is normal escape latency and is labeled non-helpless (NH). This study examines the effects of unpredictable, inescapable tail-shock stress (TSS) on alpha2-adrenoceptor (α2-AR) and corticotropin-releasing factor 1 receptor (CRF1) regulation as well as protein levels of G protein-coupled receptor kinase 3 (GRK3), GRK2, tyrosine hydroxylase (TH) plus carbonylated protein levels in locus coeruleus (LC), amygdala (AMG), cortex (COR) and striatum (STR). In NH rats, α2-AR and CRF1 receptors were significantly down-regulated in LC after TSS. No changes in these receptor levels were observed in the LC of LH rats. GRK3, which phosphorylates receptors and thereby contributes to α2-AR and CRF1 receptor down-regulation, was reduced in the LC of LH but not NH rats. GRK2 levels were unchanged. In AMG, GRK3 but not GRK2 levels were reduced in LH but not NH rats, and receptor regulation was impaired in LH rats. In STR, no changes in GRK3 or GRK2 levels were observed. Finally, protein carbonylation, an index of oxidative stress, was increased in the LC and AMG of LH but not NH rats. We suggest that reduced stress resilience after TSS may be related to oxidative stress, depletion of GRK3 and impaired regulation of α2-AR and CRF1 receptor in LC. PMID:21333691

Learned helplessness in chess players: the importance of task similarity and the role of skill.

Gobet, F R

1992-01-01

The effects of noncontingency between subjects' responses and outcomes were examined with respect to treatment-and-posttest similarity and skill in the task. The experimental design consisted of three groups. The first group had to solve chess problems with objective solutions and received veridical feedback; each member of the second group faced problems with no objective solutions, and received the same feedback as the member of the first group he was yoked with, but without any control on it; the control group received a waiting task. It was found at the end of the experiment that the group with unsolvable problems was more depressed than the two other groups. The mid-strength players were the most sensitive to the manipulation, and the weakest players showed little effect of learned helplessness. It was also found that the effects were proportional to the degree of similarity between the treatment and the posttest. The results limit the domain of applicability of the learned-helplessness model.

Although studies provide insights into the neurobiology of stress and depression, the exact molecular mechanisms underlying their pathologies remain largely unknown. Long non-coding RNA (lncRNA) has been implicated in brain functions and behavior. A potential link between lncRNA and psychiatric disorders has been proposed. However, it remains undetermined whether IncRNA regulation, in the brain, contributes to stress or depression pathologies. In this study, we used a valid animal model of depression-like symptoms; namely learned helplessness, RNA-seq, Gene Ontology and co-expression network analyses to profile the expression pattern of lncRNA and mRNA in the hippocampus of mice. We identified 6346 differentially expressed transcripts. Among them, 340 lncRNAs and 3559 protein coding mRNAs were differentially expressed in helpless mice in comparison with control and/or non-helpless mice (inescapable stress resilient mice). Gene Ontology and pathway enrichment analyses indicated that induction of helplessness altered expression of mRNAs enriched in fundamental biological functions implicated in stress/depression neurobiology such as synaptic, metabolic, cell survival and proliferation, developmental and chromatin modification functions. To explore the possible regulatory roles of the altered lncRNAs, we constructed co-expression networks composed of the lncRNAs and mRNAs. Among our differentially expressed lncRNAs, 17% showed significant correlation with genes. Functional co-expression analysis linked the identified lncRNAs to several cellular mechanisms implicated in stress/depression neurobiology. Importantly, 57% of the identified regulatory lncRNAs significantly correlated with 18 different synapse-related functions. Thus, the current study identifies for the first time distinct groups of lncRNAs regulated by induction of learned helplessness in the mouse brain. Our results suggest that lncRNA-directed regulatory mechanisms might contribute to stress-induced pathologies; in particular, to inescapable stress-induced synaptic modifications. PMID:29375311

Long non-coding RNA (lncRNA) has been implicated in brain functions and behavior. A potential link between lncRNA and psychiatric disorders has been proposed. However, it remains undetermined whether IncRNA regulation, in the brain, contributes to stress or depression pathologies. In this study, we used a valid animal model of depression-like symptoms; namely learned helplessness, RNA-seq, Gene Ontology and co-expression network analyses to profile the expression pattern of lncRNA and mRNA in the hippocampus of mice. We identified 6346 differentially expressed transcripts. Among them, 340 lncRNAs and 3559 protein coding mRNAs were differentially expressed in helpless mice in comparison with control and/or non-helpless mice (inescapable stress resilient mice). Gene Ontology and pathway enrichment analyses indicated that induction of helplessness altered expression of mRNAs enriched in fundamental biological functions implicated in stress/depression neurobiology such as synaptic, metabolic, cell survival and proliferation, developmental and chromatin modification functions. To explore the possible regulatory roles of the altered lncRNAs, we constructed co-expression networks composed of the lncRNAs and mRNAs. Among our differentially expressed lncRNAs, 17% showed significant correlation with genes. Functional co-expression analysis linked the identified lncRNAs to several cellular mechanisms implicated in stress/depression neurobiology. Importantly, 57% of the identified regulatory lncRNAs significantly correlated with 18 different synapse-related functions. Thus, the current study identifies for the first time distinct groups of lncRNAs regulated by induction of learned helplessness in the mouse brain. Our results suggest that lncRNA-directed regulatory mechanisms might contribute to stress-induced pathologies; in particular, to inescapable stress-induced synaptic modifications.

Although it has been postulated for many years that depression is associated with loss of synapses, primarily in the hippocampus, and that antidepressants facilitate synapse growth, we still lack ultrastructural evidence that changes in depressive behavior are indeed correlated with structural synaptic modifications. We analyzed hippocampal spine synapses of male rats (n=127) with electron microscopic stereology in association with performance in the learned helplessness paradigm. Inescapable footshock (IES) caused an acute and persistent loss of spine synapses in each of CA1, CA3, and dentate gyrus, which was associated with a severe escape deficit in learned helplessness. On the other hand, IES elicited no significant synaptic alterations in motor cortex. A single injection of corticosterone reproduced both the hippocampal synaptic changes and the behavioral responses induced by IES. Treatment of IES-exposed animals for 6 days with desipramine reversed both the hippocampal spine synapse loss and the escape deficit in learned helplessness. We noted, however, that desipramine failed to restore the number of CA1 spine synapses to nonstressed levels, which was associated with a minor escape deficit compared with nonstressed control rats. Shorter, 1-day or 3-day desipramine treatments, however, had neither synaptic nor behavioral effects. These results indicate that changes in depressive behavior are associated with remarkable remodeling of hippocampal spine synapses at the ultrastructural level. Because spine synapse loss contributes to hippocampal dysfunction, this cellular mechanism may be an important component in the neurobiology of stress-related disorders such as depression.
Conservative orientation as a determinant of hopelessness.

PubMed

Cheung, C K; Kwok, S T

1996-06-01

Conservative orientation is identified with reference to authoritarianism, work ethic belief, just world belief, and endorsement of individualistic causes of social problems. This over-arching orientation is hypothesized to affect hopelessness and to be affected by self-esteem with reference to ego development theory and learned helplessness theory. Causal modeling of data obtained from 1st-year college students (N = 556) in Hong Kong supports the hypotheses, showing that a student's hopelessness relates to his or her conservative orientation, even when self-esteem is controlled. This relationship can be interpreted by ego development and learned helplessness theories and cannot be explained as a spurious effect. Through the theories, hopelessness is interpreted as a result of maladaptive development and fatalistic, alienated, and helpless outlooks. This maladaptive development and the outlooks in turn result from students' conservative and individualistic orientation.

Stress-induced elevation of glucocorticoids is accompanied by structural changes and neuronal damage in certain brain areas. This includes reduced expression of brain-derived neurotrophic factor (BDNF) in the hippocampus which can be prevented by chronic electroconvulsive seizures and antidepressant drug treatment. In the last years we have bred two strains of rats, one which reacts with congenital helplessness to stress (cLH), and one which congenitally does not acquire helplessness when stressed (cNLH). After being selectively bred for more than 40 generations these strains have lost their behavioural plasticity including their sensitivity to antidepressant treatment. We show here that in cLH rats, acute immobilization stress does not induce a reduction of BDNF expression in the hippocampus which is observed in Sprague--Dawley and cNLH rats. All animals tested exhibited elevated corticosterone levels when stressed, an indication, that in cLH rats regulation of BDNF expression in the hippocampal formation is uncoupled from corticosterone increase induced through stress. This may explain the lack of adaptive responses in this strain.

Uncontrollable stress can have a profound effect on an organism's ability to respond effectively to future stressful situations. Behavior subsequent to uncontrollable stress can vary greatly between individuals, falling on a spectrum between healthy resilience and maladaptive learned helplessness. It is unclear whether dysfunctional brain activity during uncontrollable stress is associated with vulnerability to learned helplessness; therefore, we measured metabolic activity during uncontrollable stress that correlated with ensuing inability to escape future stressors. We took advantage of small animal positron emission tomography (PET) and 2-deoxy-2[(18)F]fluoro-D-glucose ((18)FDG) to probe in vivo metabolic activity in wild type Sprague Dawley rats during uncontrollable, inescapable, unpredictable foot-shock stress, and subsequently tested the animals response to controllable, escapable, predictable foot-shock stress. When we correlated metabolic activity during the uncontrollable stress with consequent behavioral outcomes, we found that the degree to which animals failed to escape the foot-shock correlated with increased metabolic activity in the lateral septum and habenula. When used a seed region, metabolic activity in the habenula correlated with activity in the lateral septum, hypothalamus, medial thalamus, mammillary nuclei, ventral tegmental area, central gray, interpeduncular nuclei, periaqueductal gray, dorsal raphe, and rostromedial tegmental nucleus, caudal linear raphe, and subiculum transition area. Furthermore, the lateral septum correlated with metabolic activity in the preoptic area, medial thalamus, habenula, interpeduncular nuclei, periaqueductal gray, dorsal raphe, and caudal linear raphe. Together, our data suggest a group of brain regions involved in sensitivity to uncontrollable stress involving the lateral septum and habenula.

Chronic antidepressant administration increases the cyclic adenosine monophosphate response element binding protein (CREB) in the amygdala, a critical neural substrate involved in the physiologic responses to stress, fear, and anxiety. To determine the role of CREB in the amygdala in animal models of depression and anxiety, a viral gene transfer approach was used to selectively express CREB in this region of the rat brain. In the learned helplessness model of depression, induction of CREB in the basolateral amygdala after training decreased the number of escape failures, an antidepressant response. However, expression of CREB before training increased escape failures, and increased immobility in the forced swim test, depressive effects. Expression of CREB in the basolateral amygdala also increased behavioral measures of anxiety in both the open field test and the elevated plus maze, and enhanced cued fear conditioning. Taken together, these data demonstrate that CREB expression in the basolateral amygdala influences behavior in models of depression, anxiety, and fear. Moreover, in the basolateral amygdala, the temporal expression of CREB in relation to learned helplessness training, determines the qualitative outcome in this animal model of depression.

The role of neuropeptide S (NPS) in depression remains unclear. We examined the antidepressant-like effects of NPS infusions into the shell or core regions of the nucleus accumbens (NAc) and into the bed nucleus of the stria terminalis (BNST) of learned helplessness (LH) rats (an animal model of depression). Infusions of NPS (10 pmol/side) into the NAc shell, but not the NAc core and BNST, exerted antidepressant-like effects in the LH paradigm. Implying that behavioral deficits could be improved in the conditioned avoidance test. Coinfusion of SHA68 (an NPS receptor antagonist, 100 pmol/side) with NPS into the NAc shell blocked these effects. In contrast, NPS receptor antagonism by SHA68 in the BNST induced antidepressant-like effects. Infusions of NPS into the NAc shell or SHA68 into the BNST did not produce memory deficits or locomotor activation in the passive avoidance and open field tests. These results suggest that excitatory and inhibitory actions by the NPS system are integral to the depression in LH animals. Copyright © 2015 Elsevier B.V. All rights reserved.

To test the hypothesis that there is an association between susceptibility to inflammation and a hyporesponsive hypothalamo-pituitary-adrenal (HPA) axis. Animals were separated on the basis of behaviour in the learned helplessness (LH) paradigm into groups of LH(+) (i.e. animals which did not escape footshock) and LH(-) animals. Adjuvant-induced arthritis (AA) was subsequently induced in the LH(+) and LH(-) animals. Plasma corticosterone was significantly increased in response to the LH test in the LH(-) compared with the LH(+) rats. We observed an earlier onset and increased inflammation in the LH(-) rats in spite of the greater corticosterone response to the acute stress. We noted lower levels of plasma testosterone in the LH(-) animals suggesting a possible influence for this protective factor in AA. These data suggest that increased onset and severity of inflammation in AA is not a simple consequence of an attenuated HPA axis response to stress as proposed in the Lewis rat. Indeed we have observed the converse. Together these data suggest that the balance of pro- and anti-inflammatory factors released in response to stress may influence the progress of AA.

According to the Seligman theory of learned helplessness, depression is caused by a repetitive experience of loss of control resulting in internal, stable and global attributional styles for negative events. In depressed patients and healthy controls experiencing such events, an increased amplitude of the post-imperative negative variation (PINV) has been described. The aim of the study was to investigate a possible correlation between migraine, depression, learned helplessness and PINV. 24 patients suffering from migraine without aura and 24 healthy controls were exposed to a situation of loss of control whilst the contingent negative variation (CNV) from C3, C4 and Cz were recorded. Before conducting the experiment, the subjects were asked to answer the Beck Depression Inventory (BDI) and the German attributional style questionnaire (GASQ). Amplitudes of total CNV, early and late component and PINV were calculated in eight blocks of four recordings each. The results confirm findings of a pronounced PINV in situations of loss of control, though high amplitudes were not correlated with low values in the GASQ and therefore with learned helplessness. High PINV in migraine patients correlated with high scores in the BDI and the list of the complaints questionnaire. However, this was not the case in healthy controls. In this experimental situation, PINV in migraine patients can be interpreted as an expectancy potential in order to avoid failure and helplessness.

The learned helplessness (LH) paradigm is characterized by learning deficits resulting from inescapable events. The aims of the present study were to determine if protein-calorie malnutrition (PCM) alters learning deficits induced by LH and if the neurochemical changes induced by malnutrition alter the reactivity to treatment with GABA-ergic and serotonergic drugs during LH. Well-nourished (W) and PCM Wistar rats (61 days old) were exposed or not to inescapable shocks (IS) and treated with gepirone (GEP, 0.0-7.5 mg/kg, intraperitoneally, N = 128) or chlordiazepoxide (0.0-7.5 mg/kg, intraperitoneally, N = 128) 72 h later, 30 min before the test session (30 trials of escape learning). The results showed that rats exposed to IS had higher escape latency than non-exposed rats (12.6 +/- 2.2 vs 4.4 +/- 0.8 s) and that malnutrition increased learning impairment produced by LH. GEP increased the escape latency of W animals exposed or non-exposed to IS, but did not affect the response of PCM animals, while chlordiazepoxide reduced the escape deficit of both W and PCM rats. The data suggest that PCM animals were more sensitive to the impairment produced by LH and that PCM led to neurochemical changes in the serotonergic system, resulting in hyporeactivity to the anxiogenic effects of GEP in the LH paradigm.

Dopaminergic system and its D1 as well as D2 receptors are involved in the modulation of emotional behavior. This experiment investigated the role of dopaminergic activity in the inescapable stress-induced learned helplessness, a widely used depression animal model, by using the pharmacological manipulation through the apomorphine (APO), an agonist for D1 and D2 receptors, and sulpiride (SUL), a selective D2 antagonist. Male Sprague Dawley rats were used and tested in a shuttle box. In the day-1 session, the rats received a 10-trial (1 min/trial) inescapable stressor: a 3 sec conditioned stimulus (CS; 75 db sound and 250 lux red light) followed by a 10 sec unconditioned stimulus (UCS; electrical foot shock, 0.5 mA). In the day-2 session, a 15-trial active avoidance test, 3 sec CS followed by UCS, was performed 30 min after the administration of APO (0, 0.05, 0.5, 1, and 5 mg/kg, i.p.). The number of failures was counted and the UCS was stopped when the rats did not escape after 15 sec UCS. The results showed that APO at the dosage of 0.5 mg/kg had a tendency to enhance the avoidance behavior. In contrast, the treatment of higher dose of APO, 1 and 5 mg/kg, reduced the number of escape but increased the number of failure. Pretreatment of SUL (5 mg/kg, i.p.), 10 min before 1 mg/kg of APO, significantly enhanced the failure behavior. The present data suggest that the activity of D2 receptor may be associated with the adaptive or protective role in the prevention of escape deficits after exposure to inescapable stress. However, the excessive stimulation of D1 receptor may participate in the failure of coping behavior leading to learned helplessness and therefore in the pathophysiological mechanisms underling the development of depression.

Objective Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that can result in disability and psychological distress. Although pain has been associated with depressive symptomatology and stress in SLE, a paucity of theoretical models have been used to explain the relationship between pain and psychological distress in this population. Thus, the present study examined helplessness as a mediator of the relationship between pain and psychological distress among patients with SLE. Methods Multiple mediation analysis was used to examine the hypothesis that learned helplessness mediates the relationship between pain and symptoms of anxiety, depression, and stress in a sample of patients with SLE ( N = 136) receiving medical care at Cedars Sinai Medical Center. Results The mean score on the Helplessness subscale was 14.5 ( SD = 5.4). Helplessness fully mediated the relationship between pain vitality and symptoms of anxiety (BCa 95% CI (-0.073, -0.015)), depression (BCa 95% CI (-0.502, -0.212)), and stress (BCa 95% CI (-0.063, -0.027)). Conclusion Participants reported a high level of perceived inability to control one's disease. Helplessness fully mediated the relationship between pain and measures of anxiety, depression, and perceived stress among patients with SLE.

Learned Helplessness and Sexual Risk Taking in Adolescent and Young Adult African American Females.

Research involving adolescent and young African American (AA) females has demonstrated that they face uncontrollable obstacles which can interfere with the negotiation of safer sexual behaviors. If these obstacles are perceived as uncontrollable, then these females may be at risk for the development of Learned Helplessness (LH). As the LH model predicts, if these obstacles are believed not to be in their control, it may lead to deficits in motivational or cognitive decision-making, deficits that could certainly influence their sexual risk taking behaviors. Therefore, the primary objective for this pilot study was to trial the Learned Helplessness Scale (LHS) to examine the perceptions of LH in this population. A convenience sample of 50 adolescent and young AA females between the ages of 16 and 21 were recruited from two clinics in Southeast Michigan. Scores on the LHS ranged from 20 to 57, with a mean score of 39.1 (standard deviation = 10.49). The higher range of scores in the sample demonstrates a continuum of LH among the participants in the study.

Some individuals are resilient, whereas others succumb to despair in repeated stressful situations. The neurobiological mechanisms underlying such divergent behavioral responses remain unclear. Here, we employed an automated method for mapping neuronal activity in search of signatures of stress responses in the entire mouse brain. We used serial two-photon tomography to detect expression of c-FosGFP – a marker of neuronal activation – in c-fosGFP transgenic mice subjected to the learned helplessness (LH) procedure, a widely used model of stress-induced depression-like phenotype in laboratory animals. We found that mice showing “helpless” behavior had an overall brain-wide reduction in the level ofmore » neuronal activation compared with mice showing “resilient” behavior, with the exception of a few brain areas, including the locus coeruleus, that were more activated in the helpless mice. In addition, the helpless mice showed a strong trend of having higher similarity in whole-brain activity profile among individuals, suggesting that helplessness is represented by a more stereotypic brain-wide activation pattern. This latter effect was confirmed in rats subjected to the LH procedure, using 2-deoxy-2[18F]fluoro-D-glucose positron emission tomography to assess neural activity. In conclusion, our findings reveal distinct brain activity markings that correlate with adaptive and maladaptive behavioral responses tostress, and provide a framework for further studies investigating the contribution of specific brain regions to maladaptive stress responses.« less

The aim of this study was to test, in patients with multiple sclerosis (MS), whether the concept of helplessness might improve the understanding of the relationship between disease severity (neurological impairment) and personality characteristics (emotional instability) on one hand, and depressive mood and fatigue severity on the other hand. Data pertain to 89 patients with a definite diagnosis of MS (Expanded Disability Status Scale [EDSS] ratings: 1-8). Helplessness, fatigue severity, depressive mood and emotional instability were rated with validated questionnaires. Model testing revealed that more neurological impairment and more emotional instability were associated with more helplessness, while higher levels of helplessness were associated with more fatigue and depressive mood. The initially observed direct relationship between EDSS and fatigue disappeared. Emotional instability also had a direct significant relationship with depressive mood, and depressive mood had only a small relationship with fatigue severity. The results indicated that helplessness affected both depressive mood and fatigue severity and that fatigue was not merely a symptom of depressive mood. The correlation between neurological impairment and fatigue severity was largely explained by the mediating effect of helplessness. These findings suggest that MS patients troubled by disabling fatigue might benefit from a psychological intervention targeting unfavourable illness cognitions.
Brain systems underlying susceptibility to helplessness and depression.

2003-09-01

There has been a relative lack of research into the neurobiological predispositions that confer vulnerability to depression. This article reviews functional brain mappings from a genetic animal model, the congenitally helpless rat, which is predisposed to develop learned helplessness. Neurometabolic findings from this model are integrated with the neuroscientific literature from other animal models of depression as well as depressed humans. Changes in four major brain systems are suggested to underlie susceptibility to helplessness and possibly depression: (a) an unbalanced prefrontal-cingulate cortical system, (b) a dissociated hypothalamic-pituitary-adrenal axis, (c) a dissociated septal-hippocampal system, and (d) a hypoactive brain reward system, as exemplified by a hypermetabolic habenula-interpeduncular nucleus pathway and a hypometabolic ventral tegmental area-striatum pathway. Functional interconnections and causal relationships among these systems are considered and further experiments are suggested, with theoretical attention to how an abnormality in any one system could affect the others.

Helplessness is a major concept in depression and a major theme in preclinical and clinical depression research. For example, in rodents and humans, the learned helplessness (LH) effect describes a specific deficit in behaviour to control aversive stimuli that is induced by prior exposure to uncontrollable aversive stimuli. The LH effect is objective and valid in that the cause of the behavioural deficit, namely uncontrollability, is clear; furthermore, the deficit induced is underlain by emotional, motivational and cognitive processes that are relevant to depression psychopathology. As a further example, helplessness, hopelessness, external locus of control and causal attribution are inter-related and major themes in psychological theories (primarily cognitive theories) of depression. Despite this broad interest in helplessness, it can be argued that its potential usefulness as a scientific and clinical concept has so far not been investigated optimally, including with respect to its application in research aimed at development of improved anti-depressant pharmacotherapy. The first aim of this review was to describe and integrate the psychological evidence and the neurobiological evidence for the LH effect in rodents and healthy humans and for helplessness in depressed patients. The second aim was to conduct three systematic reviews, namely of rodent studies of the LH effect, rodent studies of effects of psychopharmacological agents on the LH effect, and human studies of efficacy of pharmacotherapeutic and psychotherapeutic treatment on helplessness in depressed patients. With respect to the first aim, the major findings are: the specificity of the LH effect in otherwise non-manipulated rodents and healthy humans has been under-estimated, and the LH effect is a specific learned aversive uncontrollability (LAU) effect. There is theoretical and empirical support for a model in which a specific LAU effect induced by a life event of major emotional significance can function as an aetiological factor for generalised helplessness which can in turn function as an aetiological and maintenance factor for depression. However, to date such models have focused on cognitive mediating processes whereas it is emotional-motivational-cognitive processes (as proposed for the LAU effect) that need to be invoked and understood. The evidence is for analogous neural processes underlying the LAU effect in rodents and healthy humans and helplessness in depression, with the ventro-medial prefrontal cortex exhibiting aversive uncontrollability-dependent activity. With respect to the second aim, the major findings are: the LAU effect is demonstrated quite consistently using a number of different paradigms in rat but is poorly studied in mouse. The rat LAU effect can be reversed by chronic administration of monoamine reuptake inhibitors. The effects of antidepressants on human helplessness have been scarcely studied to-date. The major conclusion is that the LAU effect and generalised helplessness constitute major neuropsychological concepts of high value to future translational research aimed at increased understanding of depression and development of novel, improved antidepressant treatments.

Epidemiological studies have revealed a strong genetic contribution to the risk for depression. Both reduced hippocampal serotonin neurotransmission and brain-derived neurotrophic factor (BDNF) levels have been associated with increased depression vulnerability and are also regulated during aging. Brains from young (5 months old) and old (13 months old) congenital Learned Helplessness rats (cLH), and congenital Non Learned Helplessness rats (cNLH) were immunohistochemically stained for the serotonin transporter and subsequently stereologically quantified for estimating hippocampal serotonin fiber density. Hippocampal BDNF protein levels were measured by ELISA. An exacerbated age-related loss of serotonin fiber density specific for the CA1 area was observed in the cLH animals, whereas reduced hippocampal BDNF levels were seen in young and old cLH when compared with age-matched cNLH controls. These observations indicate that aging should be taken into account when studying the neurobiological factors behind the vulnerability for depression and that understanding the effect of aging on genetically predisposed individuals may contribute to a better understanding of the pathophysiology behind depression, particularly in the elderly.

Background: Psychologic factors affect how patients with COPD respond to attempts to improve their self-management skills. Learned helplessness may be one such factor, but there is no validated measure of helplessness in COPD. Methods: We administered a new COPD Helplessness Index (CHI) to 1,202 patients with COPD. Concurrent validity was assessed through association of the CHI with established psychosocial measures and COPD severity. The association of helplessness with incident COPD exacerbations was then examined by following subjects over a median 2.1 years, defining COPD exacerbations as COPD-related hospitalizations or ED visits. Results: The CHI demonstrated internal consistency (Cronbach α = 0.75); factor analysis was consistent with the CHI representing a single construct. Greater CHI-measured helplessness correlated with greater COPD severity assessed by the BODE (Body-mass, Obstruction, Dyspnea, Exercise) Index (r = 0.34; P < .001). Higher CHI scores were associated with worse generic (Short Form-12, Physical Component Summary Score) and respiratory-specific (Airways Questionnaire 20) health-related quality of life, greater depressive symptoms, and higher anxiety (all P < .001). Controlling for sociodemographics and smoking status, helplessness was prospectively associated with incident COPD exacerbations (hazard ratio = 1.31; P < .001). After also controlling for the BODE Index, helplessness remained predictive of COPD exacerbations among subjects with BODE Index ≤ median (hazard ratio = 1.35; P = .01), but not among subjects with higher BODE Index values (hazard ratio = 0.93; P = .34). Conclusions: The CHI is an internally consistent and valid measure, concurrently associated with health status and predictively associated with COPD exacerbations. The CHI may prove a useful tool in analyzing differential clinical responses mediated by patient-centered attributes. PMID:19837823

Coping has traditionally been measured with inventories containing many items meant to identify specific coping strategies. An alternative is to develop a shorter inventory that focusses on coping expectancies which may determine the extent to which an individual attempts to cope actively. This paper explores the usefulness and validity of a simplified seven-item questionnaire (Theoretically Originated Measure of the Cognitive Activation Theory of Stress, TOMCATS) for response outcome expectancies defined either as positive ("coping"), negative ("hopelessness"), or none ("helplessness"). The definitions are based on the Cognitive Activation Theory of Stress (CATS; Ursin and Eriksen, Psychoneuroendocrinology, 29(5):567–92, 2004). The questionnaire was tested in two different samples. First, the questionnaire was compared with a traditional test of coping and then tested for validity in relation to socioeconomic differences in self-reported health. The first study was a comparison of the brief TOMCATS with a short version of the Utrecht Coping List (UCL; Eriksen et al., Scand J Psychol, 38(3):175–82, 1997). Both questionnaires were tested in a population of 1,704 Norwegian municipality workers. The second study was a cross-sectional analysis of TOMCATS, subjective and objective socioeconomic status, and health in a representative sample of the Swedish working population in 2003–2005 (N = 11,441). In the first study, the coping item in the TOMCATS questionnaire showed an expected significant positive correlation with the UCL factors of instrumental mastery-oriented coping and negative correlations with passive and depressive scores. There were also the expected correlations for the helplessness and hopelessness scores, but there was no clear distinction between helplessness and hopelessness in the way they correlated with the UCL. In the second study, the coping item in TOMCATS and the three-item helplessness scores showed clear and monotonous gradients over a subjective socioeconomic status (SES) ladder. Positive response outcome expectancy ("coping") was related to high subjective SES and no expectancy ("helplessness") to low subjective SES. In a model including age and sex, TOMCATS scores explained more variance (r 2 = 0.16) in self-reported health than both subjective (r 2 = 0.08) and objective SES (r 2 = 0.02). The brief TOMCATS questionnaire showed acceptable and significant correlations with a traditional coping questionnaire and is sensitive enough to register systematic differences in response outcome expectancies across the socioeconomic ladder. The results furthermore confirm that psychological and learning factors contribute to the socioeconomic gradient in health.

Nitric oxide synthase (NOS) inhibitors induce antidepressant-like effects in animal models sensitive to acute drug treatment such as the forced swimming test. However, it is not yet clear if repeated treatment with these drugs is required to induce antidepressant-like effects in preclinical models. The aim of this study was to test the effect induced by acute or repeated (7 days) treatment with 7-nitroindazole (7-NI), a preferential inhibitor of neuronal NOS, in rats submitted to the learned helplessness (LH) model. In addition, we aimed at investigating if 7-NI treatment would increase brain-derived neurotrophic factor (BDNF) protein levels in the hippocampus, similarly to the effect of prototype antidepressants. Animals were submitted to a pre-test (PT) session with inescapable footshocks or habituation (no shocks) to the experimental shuttle box. Six days later they were exposed to a test with escapable footshocks. Independent groups received acute (a single injection after PT or before test) or repeated (once a day for 7 days) treatment with vehicle or 7-NI (30 mg/kg). Repeated, but not acute, treatment with 7-NI attenuated LH development. The effect was similar to repeated imipramine treatment. Moreover, in an independent experimental group, only repeated treatment with 7-NI and imipramine increased BDNF protein levels in the hippocampus. The results suggest the nitrergic system could be a target for the treatment of depressive-like conditions. They also indicate that, similar to the positive control imipramine, the antidepressant-like effects of NOS inhibition could involve an increase in hippocampal BDNF levels.

Previous studies have indicated that minocycline might function as an antidepressant drug. The aim of this study was to evaluate the antidepressant-like effects of minocycline, which is known to suppress activated microglia, using learned helplessness (LH) rats (an animal model of depression). Infusion of minocycline into the cerebral ventricle of LH rats induced antidepressant-like effects. However, infusion of minocycline into the cerebral ventricle of naïve rats did not produce locomotor activation in the open field tests, suggesting that the antidepressant-like effects of minocycline were not attributed to the enhanced locomotion. LH rats showed significantly higher serotonin turnover in the orbitofrontal cortex and lower levels of brain-derived neurotrophic factor (BDNF) in the hippocampus than control rats. However, these alterations in serotonin turnover and BDNF expression remained unchanged after treatment with minocycline. On the contrary, minocycline treatment of LH rats induced significant increases in the levels of dopamine and its metabolites in the amygdala when compared with untreated LH rats. Taken together, minocycline may be a therapeutic drug for the treatment of depression. Copyright © 2011 Elsevier Inc. All rights reserved.

In this study, we investigated whether previously stressed rats with learned helplessness (LH) paradigm could recover from depressive-like behavior four weeks after the exposure, and also whether chronic treatment with valproic acid (VPA) could prevent behavioral despair due to the second stress on days 54 in these animals. Four weeks after induction of LH, we confirmed behavioral remission in the previously stressed rats. Two-way analysis of variance (ANOVA) performed with two factors, pretreatment (LH or Control) and drug (VPA or Saline), revealed a significant main effect of the drug on immobility time in forced swimming test. Post hoc test showed a shorter immobility time in the LH+VPA group than in the LH+Saline group. Immunohistochemical study of synapsin I showed a significant effect of drug by pretreatment interaction on immunoreactivity of synapsin I in the hippocampus: its expression levels in the regions were higher in the LH+VPA group than in the LH+Saline group. These results suggest that VPA could prevent the reappearance of stress-induced depressive-like behaviors in the rats recovering from prior stress, and that the drug-induced presynaptic changes in the expression of synapsin I in the hippocampus of LH animals might be related to improved tolerance toward the stress.

Stress-induced learned helplessness (LH) in animals serves as a model of behavioral depression and some aspects of posttraumatic stress disorder. We examined whether LH behavior is associated with alterations in protein kinase A (PKA), a critical phosphorylating enzyme, how long these alterations persist after inescapable shock (IS), and whether repetition of IS prolongs the duration of LH behavior and changes in PKA. Rats were exposed to IS either on day 1 or twice, on day 1 and day 7. Rats were tested for escape latency on days 2 and 4 after day 1 IS or days 2, 8, and 14 after day 1 and day 7 IS. [(3)H]cAMP (cyclic adenosine monophosphate) binding, catalytic activity and expression of PKA subunits were determined in frontal cortex and hippocampus. Higher escape latencies were observed in rats tested on day 2 after single IS and on day 14 after repeated IS. Concurrently, reduced [(3)H]cAMP binding, PKA activity, and expression of selective PKA RIIbeta and Calpha and Cbeta subunits were observed in the brains of these rats. Repeated IS prolongs the duration of LH behavior, and LH behavior is associated with reductions in apparent activity and expression of PKA. These reductions in PKA may be critical in the pathophysiology of depression and other stress-related disorders.

The aims of this study were to compare learned helplessness (LH) and perceived self-efficacy (SE) in patients with fibromyalgia (FM) and rheumatoid arthritis (RA) and to assess their correlation with functional disability, level of perceived pain, and fatigue. This multicenter, cross-sectional study included consecutive patients (aged ≥18 years) with RA, according to the 2010 American College of Rheumatology/European League Against Rheumatism criteria, and FM, according to 2010 American College of Rheumatology criteria. Learned helplessness was measured by the Rheumatology Attitude Index, Spanish version; SE with the Arthritis Self-efficacy Scale, Spanish version; functional capacity with the Health Assessment Questionnaire (HAQ), Argentine version; depression with Center for Epidemiological Studies-Depression Scale 7-item version and perceived pain and fatigue by the visual analog scale. Disease activity was measured by the Clinical Disease Activity Index (CDAI) and disease impact with the Fibromyalgia Impact Questionnaire (FIQ). A total of 215 patients, 100 with FM and 115 with RA, were included. Mean age was 59 (SD, 14) years and 58 (SD, 13) years for FM and RA, patients respectively. Whereas LH and depression were significantly higher, SE was significantly lower in FM patients. We found a positive correlation between LH and HAQ, pain, depression, fatigue, FIQ, and CDAI in FM and RA patients. We observed a negative correlation between SE and HAQ, pain, depression, fatigue, FIQ (FM), and CDAI (RA) in both groups. Both LH and SE correlate significantly with functional capacity, perceived pain, disease activity, and disease impact in RA and FM patients. Learned helplessness was higher in patients with active disease or high disease impact, as opposed to those in remission or with low disease impact, and the reverse was true for SE. Patients with FM had significantly more LH, pain, fatigue, and depression and less SE compared with those with RA.
Helplessness and perceived pain intensity: relations to cortisol concentrations after electrocutaneous stimulation in healthy young men

Background Uncontrollable aversive events are associated with feelings of helplessness and cortisol elevation and are suitable as a model of depression. The high comorbidity of depression and pain symptoms and the importance of controllability in both conditions are clinically well-known but empirical studies are scarce. The study investigated the relationship of pain experience, helplessness, and cortisol secretion after controllable vs. uncontrollable electric skin stimulation in healthy male individuals. Methods Sixty-four male volunteers were randomly assigned to receive 30 controllable (self-administered) or uncontrollable (experimenter-administered) painful electric skin stimuli. Perceived pain intensity (PPI), subjective helplessness ratings, and salivary cortisol concentrations were assessed. PPI was assessed after stress exposure. For salivary cortisol concentrations and subjective helplessness ratings, areas under the response curve (AUC) were calculated. Results After uncontrollable vs. controllable stress exposure significantly higher PPI ratings (P = 0.023), higher subjective helplessness AUC (P < 0.0005) and higher salivary cortisol AUC (P = 0.004, t-tests) were found. Correlation analyses revealed a significant correlation between subjective helplessness AUC and PPI (r = 0.500, P < 0.0005), subjective helplessness AUC and salivary cortisol AUC (r = 0.304, P = 0.015) and between PPI and salivary cortisol AUC (r = 0.298, P = 0.017). Conclusions The results confirm the impact of uncontrollability on stress responses in humans; the relationship of PPI with subjective helplessness and salivary cortisol suggests a cognitive-affective sensitization of pain perception, particularly under uncontrollable conditions.

Wuling powder (trade name: Wuling capsule), a traditional Chinese medicine (TCM), was extracted from mycelia of precious Xylaria Nigripes (Kl.) Sacc by modern fermentation technology, and has been claimed to be fully potent in improving the signs of insomnia and cognitive deficits. Moreover, Wuling capsule was effective in treating post-stroke and orther co-cormbid depression both in clinical and in basic research. In order to clarify the molecular mechanisms of the antidepressant effect of Wuling powder, we established learned helplessness (LH) depression animal model and focused on 18kDa translocator protein (TSPO) mediated-mitophagy pathway. Mice were exposed to the inescapable e-shock (IS) once a day for three consecutive days to establish the LH model. Then mice were orally administered Wuling powder for 2 weeks. For the behavioral assessment, Shuttle box test, novelty suppressed feeding test (NSF) and forced swimming test (FST) were performed. Following the behavioral assessment, we assessed the protein expression level that were related to TSPO-mediated mitophagy signaling pathway by Western blotting analysis. Finally, immunohistochemistry method was used to assess the neuroprotective effects of Wuling powder. Compared with mice that were subjected to inescapable e-shock, Wuling powder exhibited antidepressant effect in the multiple behavioral tests. In addition, Wuling powder altered the expression level of multiple proteins related to TSPO-mediated mitophagy signaling pathway. Our results suggested that Wuling powder exhibited an obvious antidepressant effect, which could be due to the improvement of TSPO-mediated mitophagy signaling pathway. Copyright © 2016.

The lateral habenula (LHb) is activated by aversive stimuli and the omission of reward, inhibited by rewarding stimuli and is hyperactive in helpless rats-an animal model of depression. Here we test the hypothesis that congenital learned helpless (cLH) rats are more sensitive to decreases in reward size and/or less sensitive to increases in reward than wild-type (WT) control rats. Consistent with the hypothesis, we found that cLH rats were slower to switch preference between two responses after a small upshift in reward size on one of the responses but faster to switch their preference after a small downshift in reward size. cLH rats were also more risk-averse than WT rats-they chose a response delivering a constant amount of reward ("safe" response) more often than a response delivering a variable amount of reward ("risky" response) compared to WT rats. Interestingly, the level of bias toward negative events was associated with the rat's level of risk aversion when compared across individual rats. cLH rats also showed impaired appetitive Pavlovian conditioning but more accurate responding in a two-choice sensory discrimination task. These results are consistent with a negative learning bias and risk aversion in cLH rats, suggesting abnormal processing of rewarding and aversive events in the LHb of cLH rats.

Effects of a single bilateral infusion of R-enantiomer of ketamine in rat brain regions of learned helplessness model of depression were examined. A single bilateral infusion of R-ketamine into infralimbic (IL) portion of medial prefrontal cortex (mPFC), CA3 and dentate gyrus (DG) of the hippocampus showed antidepressant effects. By contrast, a single bilateral infusion of R-ketamine into prelimbic (PL) portion of mPFC, shell and core of nucleus accumbens, basolateral amygdala and central nucleus of the amygdala had no effect. This study suggests that IL of mPFC, CA3 and DG of hippocampus might be involved in the antidepressant actions of R-ketamine.
Inescapable Stress Changes Walking Behavior in Flies - Learned Helplessness Revisited.

PubMed

Batsching, Sophie; Wolf, Reinhard; Heisenberg, Martin

2016-01-01

Like other animals flies develop a state of learned helplessness in response to unescapable aversive events. To show this, two flies, one 'master', one 'yoked', are each confined to a dark, small chamber and exposed to the same sequence of mild electric shocks. Both receive these shocks when the master fly stops walking for more than a second. Behavior in the two animals is differently affected by the shocks. Yoked flies are transiently impaired in place learning and take longer than master flies to exit from the chamber towards light. After the treatment they walk more slowly and take fewer and shorter walking bouts. The low activity is attributed to the fly's experience that its escape response, an innate behavior to terminate the electric shocks, does not help anymore. Earlier studies using heat pulses instead of electric shocks had shown similar effects. This parallel supports the interpretation that it is the uncontrollability that induces the state.

Two lines of mice were bred for their opposite helpless behavior in the tail suspension test, i.e., helpless (HL) mice and non helpless (NHL) mice. The 5-HT(1A) receptor labeling was quantified by means of autoradiography with (3)H-8-OH-DPAT on brain sections from mice of these two lines. We observed a significantly higher level of (3)H-8-OH-DPAT binding sites density in HL mice comparatively to NHL mice, in the medial prefrontal, cingulate, motor and sensorial cortices, in several regions of the limbic system, such as CA3 field of hippocampus, dentate gyrus, medial and baso-medial amygdala, and in dorsal and median raphe nuclei. A chronic 21-day treatment with the antidepressant fluoxetine (10 mg/kg, i.p. daily) attenuated significantly the spontaneous helplessness in HL mice but did not alter the behavior of NHL mice. In the brain of HL mice chronically injected with fluoxetine, the elevated (3)H-8-OH-DPAT binding sites density was no longer observed after treatment in several regions, among which the raphe nuclei. Conversely, the antidepressant treatment did not modify the (3)H-8-OH-DPAT binding sites density in NHL mice. The variation of 5-HT(1A) receptors binding density in the HL mice in response to a chronic fluoxetine treatment parallels the attenuation of the spontaneous helplessness observed in the tail suspension test, and may underlie this behavior.
Synaptic Modifications in the Medial Prefrontal Cortex in Susceptibility and Resilience to Stress

When facing stress, most individuals are resilient whereas others are prone to developing mood disorders. The brain mechanisms underlying such divergent behavioral responses remain unclear. Here we used the learned helplessness procedure in mice to examine the role of the medial prefrontal cortex (mPFC), a brain region highly implicated in both clinical and animal models of depression, in adaptive and maladaptive behavioral responses to stress. We found that uncontrollable and inescapable stress induced behavioral state-dependent changes in the excitatory synapses onto a subset of mPFC neurons: those that were activated during behavioral responses as indicated by their expression of the activity reporter c-Fos. Whereas synaptic potentiation was linked to learned helplessness, a depression-like behavior, synaptic weakening, was associated with resilience to stress. Notably, enhancing the activity of mPFC neurons using a chemical–genetic method was sufficient to convert the resilient behavior into helplessness. Our results provide direct evidence that mPFC dysfunction is linked to maladaptive behavioral responses to stress, and suggest that enhanced excitatory synaptic drive onto mPFC neurons may underlie the previously reported hyperactivity of this brain region in depression.

Strong interactions between learned helplessness and risky decision-making in a rat gambling model.

Risky decision-making is characteristic of depression and of addictive disorders, including pathological gambling. However it is not clear whether a propensity to risky choices predisposes to depressive symptoms or whether the converse is the case. Here we tested the hypothesis that rats showing risky decision-making in a rat gambling task (rGT) would be more prone to depressive-like behaviour in the learned helplessness (LH) model. Results showed that baseline rGT choice behaviour did not predict escape deficits in the LH protocol. In contrast, exposure to the LH protocol resulted in a significant increase in risky rGT choices on retest. Unexpectedly, control rats subjected only to escapable stress in the LH protocol showed a subsequent decrease in riskier rGT choices. Further analyses indicated that the LH protocol affected primarily rats with high baseline levels of risky choices and that among these it had opposite effects in rats exposed to LH-inducing stress compared to rats exposed only to the escape trials. Together these findings suggest that while baseline risky decision making may not predict LH behaviour it interacts strongly with LH conditions in modulating subsequent decision-making behaviour. The suggested possibility that stress controllability may be a key factor should be further investigated.

The astrocyte is a major component of the neural network and plays a role in brain function. Previous studies demonstrated changes in the number of astrocytes in depression. In this study, we examined alterations in the number of astrocytes in the learned helplessness (LH) rat, an animal model of depression. The numbers of activated and nonactivated astrocytes in the dentate gyrus (molecular layer, subgranular zone, and hilus), and CA1 and CA3 regions of the hippocampus were significantly increased 2 and 8 days after attainment of LH. Subchronic treatment with imipramine showed a tendency (although not statistically significant) to decrease the LH-induced increment of activated astrocytes in the CA3 region and dentate gyrus. Furthermore, subchronic treatment of naïve rats with imipramine did not alter the numbers of activated and nonactivated astrocytes. However, the antidepressant-like effects of imipramine in the LH paradigm were blocked when fluorocitrate (a reversible inhibitor of astrocyte function) was injected into the dentate gyrus or CA3 region. Injection of fluorocitrate into naive rats failed to induce behavioral deficits in the conditioned avoidance test. These results indicate that astrocytes are responsive to the antidepressant-like effect of imipramine in the dentate gyrus and CA3 region of the hippocampus. Copyright © 2010 Wiley-Liss, Inc.

Discrete Serotonin Systems Mediate Memory Enhancement and Escape Latencies after Unpredicted Aversive Experience in Drosophila Place Memory

Feedback mechanisms in operant learning are critical for animals to increase reward or reduce punishment. However, not all conditions have a behavior that can readily resolve an event. Animals must then try out different behaviors to better their situation through outcome learning. This form of learning allows for novel solutions and with positive experience can lead to unexpected behavioral routines. Learned helplessness, as a type of outcome learning, manifests in part as increases in escape latency in the face of repeated unpredicted shocks. Little is known about the mechanisms of outcome learning. When fruit fly Drosophila melanogaster are exposed to unpredicted high temperatures in a place learning paradigm, flies both increase escape latencies and have a higher memory when given control of a place/temperature contingency. Here we describe discrete serotonin neuronal circuits that mediate aversive reinforcement, escape latencies, and memory levels after place learning in the presence and absence of unexpected aversive events. The results show that two features of learned helplessness depend on the same modulatory system as aversive reinforcement. Moreover, changes in aversive reinforcement and escape latency depend on local neural circuit modulation, while memory enhancement requires larger modulation of multiple behavioral control circuits.

Enoxacin Elevates MicroRNA Levels in Rat Frontal Cortex and Prevents Learned Helplessness

PubMed Central

Smalheiser, Neil R.; Zhang, Hui; Dwivedi, Yogesh

2014-01-01

Major depressive disorder (MDD) is a major public health concern. Despite tremendous advancement, the pathogenic mechanisms associated with MDD are still unclear. Moreover, a significant number of MDD subjects do not respond to the currently available medication. MicroRNAs (miRNAs) are a class of small non-coding RNAs that control gene expression by modulating translation, mRNA degradation or stability of mRNA targets. The role of miRNAs in disease pathophysiology is emerging rapidly. Recently, we reported that miRNA expression is down-regulated in frontal cortex of depressed suicide subjects, and that rats exposed to repeated inescapable shock show differential miRNA changes depending on whether they exhibited normal adaptive responses or learned helpless (LH) behavior. Enoxacin, a fluoroquinolone used clinically as an anti-bacterial compound, enhances the production of miRNAs in vitro and in peripheral tissues in vivo, but has not yet been tested as an experimental tool to study the relation of miRNA expression to neural functions or behavior. Treatment of rats with 10 or 25 mg/kg enoxacin for 1 week increased the expression of miRNAs in frontal cortex and decreased the proportion of rats exhibiting LH behavior following inescapable shock. Further studies are warranted to learn whether enoxacin may ameliorate depressive behavior in other rodent paradigms and in human clinical situations, and if so whether its mechanism is due to upregulation of miRNAs.

Increasing evidences indicate the concurrence and interrelationship of depression and cognitive impairments. The present study was undertaken to investigate the effects of two depressive animal models, learned helplessness (LH) and chronic mild stress (CMS), on the cognitive functions of mice in the Morris water maze task. Our results demonstrated that both LH and CMS significantly decreased the cognitive performance of stressed mice in the water maze task. The escaping latency to the platform was prolonged and the probe test percentage in the platform quadrant was reduced. These two models also increased the plasma corticosterone concentration and decreased the brain derived neurotrophic factor (BDNF) and cAMP-response element-biding protein (CREB) messenger ribonucleic acid (mRNA) levels in hippocampus, which might cause the spatial cognition deficits. Repeated treatment with antidepressant drugs, imipramine (Imi) and fluoxetine (Flu), significantly reduced the plasma corticosterone concentration and enhanced the BDNF and CREB levels. Furthermore, antidepressant treated animals showed an ameliorated cognitive performance compared with the vehicle treated stressed animals. These data suggest that both LH and CMS impair the spatial cognitive function and repeated treatment with antidepressant drugs decreases the prevalence of cognitive impairments induced by these two animal models. Those might in part be attributed to the reduced plasma corticosterone and enhanced hippocampal BDNF and CREB expressions. This study provided a better understanding of molecular mechanisms underlying interactions of depression and cognitive impairments, although animal models used in this study can mimic only some aspects of depression or cognition of human.

Antidepressants require adaptive brain changes before efficacy is achieved, and they may impact the affectively disordered brain differently than the normal brain. We previously demonstrated metabolic disturbances in limbic and cortical regions of the congenitally helpless rat, a model of susceptibility to affective disorder, and we wished to test whether administration of fluoxetine would normalize these metabolic differences. Fluoxetine was chosen because it has become a first-line drug for the treatment of affective disorders. We hypothesized that fluoxetine antidepressant effects may be mediated by decreasing metabolism in the habenula and increasing metabolism in the ventral tegmental area. We measured the effects of fluoxetine on forced swim behavior and regional brain cytochrome oxidase activity in congenitally helpless rats treated for 2 weeks with fluoxetine (5mg/kg, i.p., daily). Fluoxetine reduced immobility in the forced swim test as anticipated, but congenitally helpless rats responded in an atypical manner, i.e., increasing climbing without affecting swimming. As hypothesized, fluoxetine reduced metabolism in the habenula and increased metabolism in the ventral tegmental area. In addition, fluoxetine reduced the metabolism of the hippocampal dentate gyrus and dorsomedial prefrontal cortex. This study provided the first detailed mapping of the regional brain effects of an antidepressant drug in congenitally helpless rats. All of the effects were consistent with previous studies that have metabolically mapped the effects of serotonergic antidepressants in the normal rat brain, and were in the predicted direction of metabolic normalization of the congenitally helpless rat for all affected brain regions except the prefrontal cortex.

Defining the markers corresponding to a high risk of developing depression in humans would have major clinical significance; however, few studies have been conducted since they are not only complex but also require homogeneous groups. This study compared congenital learned helpless (cLH) rats, selectively bred for high stress sensitivity and learned helplessness (LH) behavior, to congenital non-learned helpless (cNLH) rats that were bred for resistance to uncontrollable stress. Naïve cLH rats show some depression-like behavior but full LH behavior need additional stress, making this model ideal for studying vulnerability to depression. Resting-state functional connectivity obtained from seed correlation analysis was calculated for multiple regions that were selected by anatomy AND by a data-driven approach, independently. Significance was determined by t-statistic AND by permutation analysis, independently. A significant reduction in functional connectivity was observed by both analyses in the cLH rats in the sensory, motor, cingulate, infralimbic, accumbens and the raphe nucleus. These reductions corresponded primarily to reduced inter-hemispheric connectivity. The main reduction however was in the sensory system. It is argued that reduced connectivity and inter-hemispheric connectivity of the sensory system reflects an internal convergence state which may precede other depressive symptomatology and therefore could be used as markers for vulnerability to the development of depression.

Research suggests that midline posterior versus frontal electroencephalographic (EEG) theta activity (PFTA) may reflect a novel neurophysiological index of approach motivation. Elevated PFTA has been associated with approach-related tendencies both at rest and during laboratory tasks designed to enhance approach motivation. PFTA is sensitive to changes in dopamine signaling within the fronto-striatal neural circuit, which is centrally involved in approach motivation, reward processing, and goal-directed behavior. To date, however, no studies have examined PFTA during a laboratory task designed to reduce approach motivation or goal-directed behavior. Considerable animal and human research supports the hypothesis put forth by the learned helplessness theory that exposure to uncontrollable aversive stimuli decreases approach motivation by inducing a state of perceived uncontrollability. Accordingly, the present study examined the effect of perceived uncontrollability (i.e., learned helplessness) on PFTA. EEG data were collected from 74 participants (mean age = 19.21 years; 40 females) exposed to either Controllable (n = 26) or Uncontrollable (n = 25) aversive noise bursts, or a No-Noise Condition (n = 23). In line with prediction, individuals exposed to uncontrollable aversive noise bursts displayed a significant decrease in PFTA, reflecting reduced approach motivation, relative to both individuals exposed to controllable noise bursts or the No-Noise Condition. There was no relationship between perceived uncontrollability and frontal EEG alpha asymmetry, another commonly used neurophysiological index of approach motivation. Results have implications for understanding the neurophysiology of approach motivation and establishing PFTA as a neurophysiological index of approach-related tendencies.

Different emotional states lead to distinct behavioural consequences even when faced with the same challenging events. Emotions affect learning and memory capacities, but the underlying neurobiological mechanisms remain elusive. Here we establish models of learned helplessness (LHL) and learned hopefulness (LHF) by exposing animals to inescapable foot shocks or with anticipated avoidance trainings. The LHF animals show spatial memory potentiation with excitatory monosynaptic upscaling between posterior basolateral amygdale (BLP) and ventral hippocampal CA1 (vCA1), whereas the LHL show memory deficits with an attenuated BLP–vCA1 connection. Optogenetic disruption of BLP–vCA1 inputs abolishes the effects of LHF and impairs synaptic plasticity. By contrast, targeted BLP–vCA1 stimulation rescues the LHL-induced memory deficits and mimics the effects of LHF. BLP–vCA1 stimulation increases synaptic transmission and dendritic plasticity with the upregulation of CREB and intrasynaptic AMPA receptors in CA1. These findings indicate that opposite excitatory monosynaptic scaling of BLP–vCA1 controls LHF- and LHL-modulated spatial memory, revealing circuit-specific mechanisms linking emotions to memory.

Inescapable Stress Changes Walking Behavior in Flies - Learned Helplessness Revisited

PubMed Central

Batsching, Sophie; Wolf, Reinhard; Heisenberg, Martin

2016-01-01

Like other animals flies develop a state of learned helplessness in response to unescapable aversive events. To show this, two flies, one 'master', one 'yoked', are each confined to a dark, small chamber and exposed to the same sequence of mild electric shocks. Both receive these shocks when the master fly stops walking for more than a second. Behavior in the two animals is differently affected by the shocks. Yoked flies are transiently impaired in place learning and take longer than master flies to exit from the chamber towards light. After the treatment they walk more slowly and take fewer and shorter walking bouts. The low activity is attributed to the fly's experience that its escape response, an innate behavior to terminate the electric shocks, does not help anymore. Earlier studies using heat pulses instead of electric shocks had shown similar effects. This parallel supports the interpretation that it is the uncontrollability that induces the state.

The study tested the Reformulated Helplessness model that individuals who show combined internal locus of control, high stability and high globality attributions for negative life events are prone to depression. Thirty-six women (M=29 years-8 months of age) receiving clinical treatment for eating disorders completed: the Attribution Style Questionnaire, the Beck Depression Inventory, and the Stirling Eating Disorder Scales. An HRA yielded a three-way interaction among the attributional dimensions on depressive symptoms. Plotting of the slopes showed that the attribution of negative life events to the combination of internal locus of control, high stability, and a high globality, was associated with the optimal level of depressive symptoms. The findings supported the Reformulated Helplessness as a model of depression. Copyright © 2012 Elsevier Ltd. All rights reserved.

One of social problems which has affected our society and resulted in problems for different groups of people is drug abuse. This issue indicates a serious psychological, physical and social problem in community. Social skills have positive and successful influences in prevention of substance abuse. This includes the ability to explain events correctly and then appropriate decision making. This study compares decision making styles and attributional styles between addicted and non addicted men to recognize their role in addiction. In this study, 200 addicted and non addicted men were randomly selected. Decision-making style and attributional style questionnaires were used. Data analysis was performed by independent Student's t and Pearson correlation tests. The study population included 81 addicted and 90 non-addicted men. Addicted and non addicted men were significantly different in rational decision-making style (P < 0.05). Negative relationship was found between rational decision making and optimistic attribution style (r = -0.305, P < 0.01) and direct relationship was found between rational decision making and learned helplessness (r = 0.309, P < 0.01). Our study showed that addicts are less rational in decision making and addicts that developed learned helplessness were less rational and did not have optimistic attribution style. These issues show that addiction institutions and therapists have to pay attention to cognitive factors for addiction prevention.

Yueju pill is a traditional Chinese medicine formulated to treat syndromes of mood disorders. Here, we investigated the therapeutic effect of repeated low dose of Yueju in the animal model mimicking clinical long-term depression condition and the role of neural plasticity associated with PKA- (protein kinase A-) CREB (cAMP response element binding protein) and NMDA (N-methyl-D-aspartate) signaling. We showed that a single low dose of Yueju demonstrated antidepressant effects in tests of tail suspension, forced swim, and novelty-suppressed feeding. A chronic learned helplessness (LH) protocol resulted in a long-term depressive-like condition. Repeated administration of Yueju following chronic LH remarkably alleviated all of depressive-like symptoms measured, whereas conventional antidepressant fluoxetine only showed a minor improvement. In the hippocampus, Yueju and fluoxetine both normalized brain-derived neurotrophic factor (BDNF) and PKA level. Only Yueju, not fluoxetine, rescued the deficits in CREB signaling. The chronic LH upregulated the expression of NMDA receptor subunits NR1, NR2A, and NR2B, which were all attenuated by Yueju. Furthermore, intracerebraventricular administration of NMDA blunted the antidepressant effect of Yueju. These findings supported the antidepressant efficacy of repeated routine low dose of Yueju in a long-term depression model and the critical role of CREB and NMDA signaling. PMID:29075536

Attributional style and depression in multiple sclerosis: the learned helplessness model.

Vargas, Gray A; Arnett, Peter A

Several etiologic theories have been proposed to explain depression in the general population. Studying these models and modifying them for use in the multiple sclerosis (MS) population may allow us to better understand depression in MS. According to the reformulated learned helplessness (LH) theory, individuals who attribute negative events to internal, stable, and global causes are more vulnerable to depression. This study differentiated attributional style that was or was not related to MS in 52 patients with MS to test the LH theory in this population and to determine possible differences between illness-related and non-illness-related attributions. Patients were administered measures of attributional style, daily stressors, disability, and depressive symptoms. Participants were more likely to list non-MS-related than MS-related causes of negative events on the Attributional Style Questionnaire (ASQ), and more-disabled participants listed significantly more MS-related causes than did less-disabled individuals. Non-MS-related attributional style correlated with stress and depressive symptoms, but MS-related attributional style did not correlate with disability or depressive symptoms. Stress mediated the effect of non-MS-related attributional style on depressive symptoms. These results suggest that, although attributional style appears to be an important construct in MS, it does not seem to be related directly to depressive symptoms; rather, it is related to more perceived stress, which in turn is related to increased depressive symptoms.
Towards clarification of convergent concepts: sense of coherence, will to meaning, locus of control, learned helplessness and hardiness.

The multidisciplinary field of stress and stress-related health outcomes has generated theoretical and practical knowledge which is of interest to nurses. Theoretical developments which have assumed a prominent role in the study of stress, health and coping include the identification of various 'stress buffers' several of which bear a strong conceptual resemblance to one another. Antonovsky has developed a Salutogenic Model of stress and resistance, which is presented in this paper. The model's central concept, the sense of coherence, is described and analysed. The sense of coherence, with its three components (meaningfulness, comprehensibility and manageability), is then compared and contrasted with similar concepts. The convergent theoretical notions which are distinguished from Antonovsky's coherence are: will to meaning, locus of control, learned helplessness and hardiness. It is hoped that this analysis will provide greater conceptual clarity for nurses who study and use these concepts in education, practice or research.
Childhood Poverty, Cumulative Risk Exposure, and Mental Health in Emerging Adults

One out of four American children are born into poverty, but little is known about the long-term, mental health implications of early deprivation. The more time in poverty from birth-age-9, the worse mental health as emerging adults (n = 196, M = 17.30 years, 53% male). These results maintain independently of concurrent, adult income levels for self-reported externalizing symptoms and a standard learned helplessness behavioral protocol, but internalizing symptoms were unaffected by childhood poverty. We then demonstrate that part of the reason why early poverty exposure is harmful to mental health among emerging adults is because of elevated cumulative risk exposure assessed at age 13. The significant, prospective, longitudinal relations between early childhood poverty and externalizing symptoms plus learned helplessness behavior are mediated, in part, by exposure to a confluence of psychosocial (violence, family turmoil, child separation from family) and physical (noise, crowding, substandard housing) risk factors during adolescence.

Wakan-yaku is a type of Japanese and Sino traditional, systematized medical care that has been practiced for hundreds of years. This medicinal system includes many antidepressive prescriptions. One of the candidates is Hochuekkito, although experimental evidence has not yet been established clearly. To obtain evidence, a depression model of learned-helplessness (LH) mice was used. Based on the score of escape failure, an index of the depression degree, mice with a depressive condition were selected to assess Hochuekkito's effects. This selection was significant and effective in the following two points: evaluation of the drug effect under disease conditions and minimization of the number of animals. Treatment with Hochuekkito (1 and 5 g/kg p.o.; estimated galenical amount) for 14 days significantly decreased the depression index, the number of escape failures, and desipramine (10 mg/kg p.o.) suggesting that Hochuekkito has an antidepressive effect.

In the learned helplessness (LH) animal model of depression, failure to attempt escape from avoidable environmental stress, LH, indicates behavioral despair, whereas nonhelpless (NH) behavior reflects behavioral resilience to the effects of environmental stress. Comparing hippocampal gene expression with large-scale oligonucleotide microarrays, we found that stress-resilient (NH) rats, although behaviorally indistinguishable from controls, showed a distinct gene expression profile compared to LH, sham stressed, and naïve control animals. Genes that were confirmed as differentially expressed in the NH group by quantitative PCR strongly correlated in their levels of expression across all four animal groups. Differential expression could not be confirmed at the protein level. We identified several shared degenerate sequence motifs in the 3' untranslated region (3'UTR) of differentially expressed genes that could be a factor in this tight correlation of expression levels among differentially expressed genes.

Experiencing feelings of helplessness has repeatedly been reported to contribute to depressive symptoms and negative affect. In turn, depression and negative affective states are associated, among others, with impairments in performance monitoring. Thus, the question arises whether performance monitoring is also affected by feelings of helplessness. To this end, after the induction of feelings of helplessness via an unsolvable reasoning task, 37 participants (20 females) performed a modified version of a Flanker task. Based on a previously validated questionnaire, 17 participants were classified as helpless and 20 as not-helpless. Behavioral measures revealed no differences between helpless and not-helpless individuals. However, we observed enhanced Error-Related Negativity (ERN) amplitude differences between erroneous and correct responses in the helpless compared to the not-helpless group. Furthermore, correlational analysis revealed that higher scores of helplessness were associated with increased ERN difference scores. No influence of feelings of helplessness on later stages of performance monitoring was observed as indicated by Error-Positivity (Pe) amplitude. The present study is the first to demonstrate that feelings of helplessness modulate the neuronal correlates of performance monitoring. Thus, even a short-lasting subjective state manipulation can lead to ERN amplitude variation, probably via modulation of mesencephalic dopamine activity. PMID:23267824

Disturbances in cognitive functioning are among the most debilitating problems experienced by patients with major depression. Investigations of these deficits in animals help to extend and refine our understanding of human emotional disorder, while at the same time providing valid tools to study higher executive functions in animals. We employ the “learned helplessness” genetic rat model of depression in studying working memory using an eight arm radial maze procedure with temporal delay. This so-called delayed spatial win-shift task consists of three phases, training, delay and test, requiring rats to hold information on-line across a retention interval and making choices based on this information in the test phase. According to a 2×2 factorial design, working memory performance of thirty-one congenitally helpless (cLH) and non-helpless (cNLH) rats was tested on eighteen trials, additionally imposing two different delay durations, 30 s and 15 min, respectively. While not observing a general cognitive deficit in cLH rats, the delay length greatly influenced maze performance. Notably, performance was most impaired in cLH rats tested with the shorter 30 s delay, suggesting a stress-related disruption of attentional processes in rats that are more sensitive to stress. Our study provides direct animal homologues of clinically important measures in human research, and contributes to the non-invasive assessment of cognitive deficits associated with depression.

The associations between socioeconomic status (SES), physical and psychosocial workload and health are well documented. According to The Cognitive Activation Theory of Stress (CATS), learned response outcome expectancies (coping, helplessness, and hopelessness) are also important contributors to health. This is in part as independent factors for health, but coping may also function as a buffer against the impact different demands have on health. The purpose of this study was to investigate the relative effect of SES (as measured by level of education), physical workload, and response outcome expectancies on subjective health complaints (SHC) and self-rated health, and if response outcome expectancies mediate the effects of education and physical workload on SHC and self-rated health. A survey was carried out among 1,746 Norwegian municipal employees (mean age 44.2, 81 % females). Structural Equation Models with SHC and self-rated health as outcomes were conducted. Education, physical workload, and response outcome expectancies, were the independent 28 variables in the model. Helplessness/hopelessness had a stronger direct effect on self-rated health and SHC than education and physical workload, for both men and women. Helplessness/hopelessness fully mediated the effect of physical workload on SHC for men (0.121), and mediated 30 % of a total effect of 0.247 for women. For women, education had a small but significant indirect effect through helplessness/hopelessness on self-rated health (0.040) and SHC (-0.040), but no direct effects were found. For men, there was no effect of education on SHC, and only a direct effect on self-rated health (0.134). The results indicated that helplessness/hopelessness is more important for SHC and health than well-established measures on SES such as years of education and perceived physical workload in this sample. Helplessness/hopelessness seems to function as a mechanism between physical workload and health.
WINDOWS OF VULNERABILITY: MATERNAL SEPARATION, AGE, AND FLUOXETINE ON ADOLESCENT DEPRESSIVE-LIKE BEHAVIOR IN RATS

Early exposure to stressful life events plays a significant role in adolescent depression. Clinical studies have identified a number of factors that increase the risk of depression, including sex of the subject, duration of the stressor, and genetic polymorphisms that elevate serotonin levels. In this study we used the maternal separation (MS) model to investigate to what extent these factors interacted during development to manifest in depressive-like behavior in male and female rats. The triadic model of learned helplessness parses depressive-like behavior into aspects of controllable, uncontrollable, and motivational behaviors. This model was used to investigate how the timing of MS between the ages of postnatal day (P) 2–9 and P9–16 interacted with either simultaneous vehicle (saline; 1 ml/kg; i.p.) or fluoxetine (10 mg/kg) exposure, which was used to enhance serotonin levels; these experiments also compared the effect of a vehicle injection during these developmental periods to a no injection control. Vehicle injections alone increased helplessness in the controllable condition in male rats when injected between P9–16 only, and did not interact further with MS. MS at both ages decreased controllability in male adolescents; females demonstrated an increase in controllability after MS. Elevated serotonin at P2–9 increased escape latencies in male and female control and MS subjects. Fluoxetine exposure at P9–16 increased helplessness in controls. Fluoxetine decreased helplessness in MS males independent of age, but increases helplessness in MS females. This study highlights the importance of age of MS (MS between P2–9 increases helplessness in males more than females), the duration of the stressor (previous results show females are effected by longer MS [P2–20], but not shorter [this study]), and that elevated serotonin increases escape latencies to a greater extent in females.

Acute trauma can lead to life-long changes in susceptibility to psychiatric disease, such as post-traumatic stress disorder (PTSD). Rats given free access to a concentrated glucose solution for 24 h beginning immediately after trauma failed to show stress-related pathology in the learned helplessness model of PTSD and comorbid major depression. We assessed effective dosing and temporal constraints of the glucose intervention in three experiments. We exposed 120 male Sprague-Dawley rats to 100, 1 mA, 3-15 s, inescapable and unpredictable electric tail shocks (over a 110-min period) or simple restraint in the learned helplessness procedure. Rats in each stress condition had access to a 40% glucose solution or water. We measured fluid consumption under 18-h free access conditions, or limited access (1, 3, 6, 18 h) beginning immediately after trauma, or 3-h access with delayed availability of the glucose solution (0, 1, 3, 6 h). We hypothesized that longer and earlier access following acute stress would improve shuttle-escape performance. Rats exposed to traumatic shock and given 18-h access to glucose failed to show exaggerated fearfulness and showed normal reactivity to foot shock during testing as compared to their water-treated counterparts. At least 3 h of immediate post-stress access to glucose were necessary to see these improvements in test performance. Moreover, delaying access to glucose for more than 3 h post-trauma yielded no beneficial effects. These data clearly identify limits on the post-stress glucose intervention. In conclusion, glucose should be administered almost immediately and at the highest dose after trauma.

Cdk5 is a member of cyclin-dependent kinase (Cdk), a proline-directed serine/threonine kinase, and plays a key role in normal neural development and function. Evidence of previous study showed that chronic inhibition of Cdk5 in hippocampal dentate gyrus (DG) blocked the development of depressive-like symptoms, suggesting that Cdk5 plays a role in development of depression. Forced swim test, novelty-suppressed feeding test, and learned helplessness were used to evaluate the cellular and molecular mechanisms underlying the behavioral regulation of Cdk5 inhibitors in rats. Two Cdk5 inhibitors butyrolactone and roscovitine were used to investigate the possible antidepressant-like actions of Cdk5 blockade and the potential mechanisms. Systemic administration of butyrolactone (200 mg/kg, IP) or roscovitine (100 mg/kg, IP) produced effective antidepressant-like actions. Moreover, infusion (5 mM) of GSK3β activator LY294002 into DG abolished the antidepressant-like actions of butyrolactone and roscovitine, suggesting that inhibition of GSK3β might be involved in the antidepressant effect of Cdk5 inhibitors. Moreover, pretreatment of LY294002 (5 mM) blocked the antidepressant-like effect of butyrolactone and roscovitine in learned helplessness. Additionally, inescapable footshock induced a significant increase of GSK3β activity, while butyrolactone and roscovitine decreased GSK3β activity. In contrast, pretreatment of LY294002 prevented the inhibitory effects of butyrolactone and roscovitine on GSK3β activation. Finally, a specific GSK3β inhibitor, SB216763 (1 ng, DG), demonstrated an effective antidepressant-like action. These findings demonstrate that systemic administration of Cdk5 inhibitors produced antidepressant-like actions and that inhibition of GSK3β is involved in behavioral response of Cdk5 inhibitors.

Stress is a common antecedent reported by people suffering major depression. In these patients, extrahypothalamic brain areas, like the hippocampus and basolateral amygdala (BLA), have been found to be affected. The BLA synthesizes CRF, a mediator of the stress response, and projects to hippocampus. The main hippocampal target for this peptide is the CRF subtype 1 receptor (CRF1). Evidence points to a relationship between dysregulation of CRF/CRF1 extrahypothalamic signaling and depression. Because selective serotonin reuptake inhibitors (SSRIs) are the first-line pharmacological treatment for depression, we investigated the effect of chronic treatment with the SSRI fluoxetine on long-term changes in CRF/CRF1 signaling in animals showing a depressive-like behavior. Male Wistar rats were exposed to the learned helplessness paradigm (LH). After evaluation of behavioral impairment, the animals were treated with fluoxetine (10 mg/kg i.p.) or saline for 21 days. We measured BLA CRF expression with RT-PCR and CRF1 expression in CA3 and the dentate gyrus of the hippocampus with in situ hybridization. We also studied the activation of one of CRF1's major intracellular signaling targets, the extracellular signal-related kinases 1 and 2 (ERK1/2) in CA3. In saline-treated LH animals, CRF expression in the BLA increased, while hippocampal CRF1 expression and ERK1/2 activation decreased. Treatment with fluoxetine reversed the changes in CRF and CRF1 expressions, but not in ERK1/2 activation. In animals exposed to the learned helplessness paradigm, there are long-term changes in CRF and CRF1 expression that are restored with a behaviorally effective antidepressant treatment.

Serotonin (5-HT) neurons in the dorsal raphe nucleus (DRN) are implicated in mediating learned helplessness (LH) behaviors, such as poor escape responding and expression of exaggerated conditioned fear, induced by acute exposure to uncontrollable stress. DRN 5-HT neurons are hyperactive during uncontrollable stress, resulting in desensitization of 5-HT type 1A (5-HT1A) inhibitory autoreceptors in the DRN. 5-HT1A autoreceptor downregulation is thought to induce transient sensitization of DRN 5-HT neurons, resulting in excessive 5-HT activity in brain areas that control the expression of learned helplessness behaviors. Habitual physical activity has antidepressant/anxiolytic properties and results in dramatic alterations in physiological stress responses, but the neurochemical mediators of these effects are unknown. The current study determined the effects of 6 weeks of voluntary freewheel running on LH behaviors, uncontrollable stress-induced activity of DRN 5-HT neurons, and basal expression of DRN 5-HT1A autoreceptor mRNA. Freewheel running prevented the shuttle box escape deficit and the exaggerated conditioned fear that is induced by uncontrollable tail shock in sedentary rats. Furthermore, double c-Fos/5-HT immunohistochemistry revealed that physical activity attenuated tail shock-induced activity of 5-HT neurons in the rostral-mid DRN. Six weeks of freewheel running also resulted in a basal increase in 5-HT1A inhibitory autoreceptor mRNA in the rostral-mid DRN. Results suggest that freewheel running prevents behavioral depression/LH and attenuates DRN 5-HT neural activity during uncontrollable stress. An increase in 5-HT1A inhibitory autoreceptor expression may contribute to the attenuation of DRN 5-HT activity and the prevention of LH in physically active rats.

Patients with depression showed a decrease in plasma and cerebrospinal fluid allopregnanolone (ALLO). But antidepressants increased the contents of ALLO in the rat brain. We examined the antidepressant-like effects of infusion of ALLO into the cerebral ventricle, hippocampus, amygdala, nucleus accumbens, or prefrontal cortex of learned helplessness (LH) rats (an animal model of depression). Of these regions, infusions of ALLO into the cerebral ventricle, the CA3 region of hippocampus, or the central region of amygdala exerted antidepressant-like effects. Infusion of ALLO into the hippocampal CA3 region or the central amygdala did not produce memory deficits or locomotor activation in the passive avoidance and open field tests. It is well documented that ALLO exerts its effects through GABA receptors. Therefore, we examined the antagonistic effects of flumazenil (a GABA receptor antagonist) on the antidepressant-like effects of ALLO. Coinfusion of flumazenil with ALLO into the hippocampal CA3 region, but not into the central amygdala, blocked the antidepressant-like effects of ALLO. However, coinfusion of (+)MK801 (an NMDA receptor antagonist), but not cycloheximide (a protein synthesis inhibitor), blocked the antidepressant-like effects of ALLO in the central amygdala. These results suggest that ALLO exerts antidepressant-like effects in the CA3 region of hippocampus through the GABA system and in the central region of amygdala, dependently on the activation of the glutamatergic mechanisms.

Waikar, S V; Craske, M G

1997-01-01

Expectancies about future life events were assessed in anxious and depressed patients to test predictions of the Helplessness/Hopelessness model of anxiety and depression (Alloy, Kelly, Mineka, & Clements, 1990). In addition to expectancies for future events, patients from affective and anxiety treatment clinics completed anxiety and depression symptom ratings and positive and negative affects scales. Findings revealed partial support for the model. Negative outcome and helplessness expectancies were related specifically to depression. Cognitions regarding future positive events were interrelated and associated with symptom measures more strongly than were cognitions regarding negative events. Additionally, positive affects was more strongly related to depression than to anxiety symptom ratings. Implications and limitations of these findings are discussed.
Sequences of emotional distress expressed by clients and acknowledged by therapists: are they associated more with some therapists than others?

When clients come to psychotherapy they are distressed, this distress usually being expressed in the form of anxiety, hostility, depression and helplessness. This study explored the sequences of emotional distress expressed by clients and acknowledged by therapists, and examined their associations with other factors. The transcripts of five therapists (two single sessions each) were content-analysed: they used personal construct, client centered, rational-emotive, Gestalt and transactional analysis therapy. Log-linear analyses of appropriate contingency table cell frequencies were conducted to test associations between identified sequences and the two variables of therapist and timing of completion of the sequence. Therapist-client sequences of Anxiety-Anxiety, Anxiety-Hostility and Helplessness-Hostility were found to be associated more with the personal construct and client centred therapists than with the rational-emotive therapist. Client-therapist sequences of Anxiety-Anxiety, Helplessness-Anxiety and Helplessness-Helplessness were more often found with the client centred therapist than the other therapists. For most of these sequences timing had an effect, yet timing rarely interacted with the therapist variable. The findings are discussed in terms of their relevance to the theoretical positions represented, the shortcomings of the research and the value of this methodology in studies linking therapy process with outcome.

This study evaluated the contribution of condition-specific helplessness and loss to depression in fibromyalgia (FM). Two models were tested. The first model examined whether loss, measured by the West Haven-Yale Multidimensional Pain Inventory (WHYMPI) Interference Scale, would mediate the relationship between disability and depression. The second model determined whether condition-specific helplessness and loss would mediate the relationship between pain and depression with disability controlled. Eighty patients with confirmed diagnoses of FM were recruited throughout Southern California from general medical clinics, newspaper advertisements, and rheumatology practices. The study design was cross-sectional, using self-report, observational, and interview measures. A composite measure of depression was adopted, consisting of the Center for Epidemiological Studies-Depression Scale and the Hamilton Rating Scale for Depression. Hierarchical multiple regression analyses were conducted using a path analytic framework to examine each model. In Model 1, loss fully mediated the relationship between disability and depression. In Model 2, condition-specific helplessness mediated the relationship between pain and depression, but the contribution of loss was not significant. The findings confirm the importance of helplessness and demonstrate that the cognitive meaning of having FM plays a more central role in predicting depressive symptomatology than illness-related stressors, such as pain or disability.

Background: Major depression has multiple comorbidities, in particular drug use disorders, which often lead to more severe and difficult-to-treat illnesses. However, the mechanisms linking these comorbidities remain largely unknown. Methods: We investigated how a depressive-like phenotype modulates cocaine-related behaviors using a genetic model of depression: the Helpless H/Rouen (H) mouse. We selected the H mouse line for its long immobility duration in the tail suspension test when compared to non-helpless (NH) and intermediate (I) mice. Since numerous studies revealed important sex differences in drug addiction and depression, we conducted behavioral experiments in both sexes. Results: All mice, regardless of phenotype or sex, developed a similar behavioral sensitization after 5 daily cocaine injections (10 mg/kg). Male H and NH mice exhibited similar cocaine-induced conditioned place preference scores that were only slightly higher than in I mice, whereas female H mice strikingly accrued much higher preferences for the cocaine-associated context than those of I and NH mice. Moreover, female H mice acquired cocaine-associated context learning much faster than I and NH mice, a facilitating effect that was associated to a rapid increase in striatal and accumbal brain-derived neurotrophic factor levels (BDNF; up to 35% 24 h after cocaine conditioning). Finally, when re-exposed to the previously cocaine-associated context, female H mice displayed greater Fos activation in the cingulate cortex, nucleus accumbens, and basolateral amygdala. Conclusions: Our data indicate that neurobiological mechanisms such as alterations in associative learning, striato-accumbal BDNF expression, and limbic-cortico-striatal circuit reactivity could mediate enhanced cocaine vulnerability in female depressive-like mice.

In this study we made an effort to identify the kinds of strategies adolescents deploy in achievement context in an unselected sample of Swedish adolescents. The participants were 880 14-15-year-old comprehensive school students (399 boys and 481 girls) from a middle-sized town in central Sweden. Six groups of adolescents were identified according to the strategies they deployed. Four of them, i.e. optimistic, defensive pessimistic, self-handicapping and learned helplessness strategies, were similar to those described previously in the literature. The results showed that membership in the functional strategy groups, such as in mastery-oriented and defensive pessimist groups, was associated with well-being, school adjustment and achievement, and low levels of norm-breaking behaviour. By contrast, membership in the dysfunctional, for example self-handicapping and learned helplessness strategy groups, was associated with low levels of well-being, and of school adjustment, and a higher level of norm-breaking behaviour.

[Learned helplessness, generalized self-efficacy, and immune function].

Generalized self-efficacy is considered one of important personality traits that determine psychological and physiological stress responses. The present study examined the interaction effects of generalized self-efficacy and controllability of acute stress on salivary secretory immunoglobulin A (s-IgA), task performance, and psychological stress responses in a typical learned helplessness paradigm. Twenty low and 19 high self-efficacy undergraduate women performed two response selection tasks one after another. In the first task, they were exposed to controllable or uncontrollable aversive noise. The second task was identical for all, but perceived controllability was higher for the high self-efficacy group than the low. Performance under uncontrollable condition was lower than controllable condition. The interaction of self-efficacy and controllability was observed only on the s-IgA variable; increase of secretion of s-IgA secretion under stressor uncontrollability was more prominent in the low self-efficacy group than the high. These results suggested that generalized self-efficacy was a moderator of the stressor controllability effect on secretory immunity.
Learned helplessness and responses to nerve blocks in chronic low back pain patients.

Chapman, S L; Brena, S F

1982-01-01

In a double-blind study, 67 chronic low back pain patients received 4 lumbar sympathetic nerve blocks, two given with bupivacaine and two given with saline. It was hypothesized that patients showing evidence of 'learned helplessness,' as measured by dependence on habit-forming medications for the pain, low activity levels, and elevated MMPI scores on Hypochondriasis, Depression and Hysteria would show the least reduction in subjective pain intensity following injections with both bupivacaine and saline. It also was hypothesized that placebo responses would be greatest in patients who had a high educational level, were divorced, and had no pending disability claims. Responses 30 min following nerve blocks failed to correlate with these variables. However, decreases in subjective pain intensity 24 h following both types of nerve blocks were greater in patients who showed low levels of pain behavior, who were divorced, and who had no pending disability claims. Decreased pain 24 h following saline injections was significantly related to low scores on the Lie, Defensiveness, Hypochondriasis, and Hysteria scales of the MMPI and to reduced subjective pain intensity following a 6 week comprehensive outpatient pain rehabilitation program. It was concluded that chronic pain patients who are fixed in their focus on pain, high in pain-related behaviors, and low in responsibilities are less likely to respond favorably to nerve blocks and that medical treatment for them needs to be paired with therapies designed to reduce their helplessness.
The effects of "psychological inoculation" versus ventilation on the mental resilience of Israeli citizens under continuous war stress.

Anxiety and hopelessness are common reactions of citizens exposed to continuous war threats. Common interventions focus on support, calming, and emotional ventilation, with few attempts to reduce people's cognitive barriers concerning active coping, which could increase their resilience. This study tested the effects of psychological inoculation (PI), which specifically aims to challenge such barriers, on the mental resilience of Israeli citizens living in Sderot. Participants were randomly assigned to either 2 PI sessions or 2 ventilation sessions, provided over the phone. Anxiety, helplessness, pessimism, and functioning were briefly assessed at baseline and 1 week after interventions. No time, group, or group x time interactions were observed. However, a time x group x sex interaction emerged for helplessness: Men benefited from the PI whereas women benefited from ventilation, in reducing helplessness. Under chronic war stress, it seems difficult to improve people's resilience, although PI may be partly beneficial for men. Further research is needed to test the effects of PI on mental resilience.
A Bayesian formulation of behavioral control.

Huys, Quentin J M; Dayan, Peter

Helplessness, a belief that the world is not subject to behavioral control, has long been central to our understanding of depression, and has influenced cognitive theories, animal models and behavioral treatments. However, despite its importance, there is no fully accepted definition of helplessness or behavioral control in psychology or psychiatry, and the formal treatments in engineering appear to capture only limited aspects of the intuitive concepts. Here, we formalize controllability in terms of characteristics of prior distributions over affectively charged environments. We explore the relevance of this notion of control to reinforcement learning methods of optimising behavior in such environments and consider how apparently maladaptive beliefs can result from normative inference processes. These results are discussed with reference to depression and animal models thereof.

Major depressive disorder is associated with disturbed circadian rhythms. To investigate the causal relationship between mood disorders and circadian clock disruption, previous studies in animal models have employed light/dark manipulations, global mutations of clock genes, or brain area lesions. However, light can impact mood by noncircadian mechanisms; clock genes have pleiotropic, clock-independent functions; and brain lesions not only disrupt cellular circadian rhythms but also destroy cells and eliminate important neuronal connections, including light reception pathways. Thus, a definitive causal role for functioning circadian clocks in mood regulation has not been established. We stereotactically injected viral vectors encoding short hairpin RNA to knock down expression of the essential clock gene Bmal1 into the brain's master circadian pacemaker, the suprachiasmatic nucleus (SCN). In these SCN-specific Bmal1-knockdown (SCN-Bmal1-KD) mice, circadian rhythms were greatly attenuated in the SCN, while the mice were maintained in a standard light/dark cycle, SCN neurons remained intact, and neuronal connections were undisturbed, including photic inputs. In the learned helplessness paradigm, the SCN-Bmal1-KD mice were slower to escape, even before exposure to inescapable stress. They also spent more time immobile in the tail suspension test and less time in the lighted section of a light/dark box. The SCN-Bmal1-KD mice also showed greater weight gain, an abnormal circadian pattern of corticosterone, and an attenuated increase of corticosterone in response to stress. Disrupting SCN circadian rhythms is sufficient to cause helplessness, behavioral despair, and anxiety-like behavior in mice, establishing SCN-Bmal1-KD mice as a new animal model of depression.

Restoring mood balance in depression: ketamine reverses deficit in dopamine-dependent synaptic plasticity.

PubMed

Belujon, Pauline; Grace, Anthony A

2014-12-15

One of the most novel and exciting findings in major depressive disorder research over the last decade is the discovery of the fast-acting and long-lasting antidepressant effects of ketamine. Indeed, the therapeutic effects of classic antidepressants, such as selective serotonin reuptake inhibitors, require a month or longer to be expressed, with about a third of major depressive disorder patients resistant to treatment. Clinical studies have shown that a low dose of ketamine exhibits fast-acting relatively sustained antidepressant action, even in treatment-resistant patients. However, the mechanisms of ketamine action at a systems level remain unclear. Wistar-Kyoto rats were exposed to inescapable, uncontrollable footshocks. To evaluate learned helplessness behavior, we used an active avoidance task in a shuttle box equipped with an electrical grid floor. After helplessness assessment, we performed in vivo electrophysiological recordings first from ventral tegmental area dopaminergic (DA) neurons and second from accumbens neurons responsive to fimbria stimulation. Ketamine was injected and tested on helpless behavior and electrophysiological recordings. We show that ketamine is able to restore the integrity of a network by acting on the DA system and restoring synaptic dysfunction observed in stress-induced depression. We show that part of the antidepressant effect of ketamine is via the DA system. Indeed, injection of ketamine restores a decreased dopamine neuron population activity, as well as synaptic plasticity (long-term potentiation) in the hippocampus-accumbens pathway, via, in part, activation of D1 receptors. This work provides a unique systems perspective on the mechanisms of ketamine on a disrupted limbic system. Copyright © 2014 Society of Biological Psychiatry. Published by Elsevier Inc.

Learned helplessness activates hippocampal microglia in rats: A potential target for the antidepressant imipramine.

PubMed

Iwata, Masaaki; Ishida, Hisahito; Kaneko, Koichi; Shirayama, Yukihiko

An accumulating body of evidence has demonstrated that inflammation is associated with the pathology of depression. We recently found that psychological stress induces inflammation in the hippocampus of the rat brain through the inflammasome, a component of the innate immune system. Microglia, the resident macrophages in the brain, play a central role in the innate immune system and express inflammasomes; thus, we hypothesized that hippocampal microglia would be key mediators in the development of depression via stress-induced inflammation. To test this hypothesis and to determine how antidepressants modulate microglial function, we used immunohistochemistry to examine the morphological changes that occur in the hippocampal microglia of rats exposed to the learned helplessness (LH) paradigm. We noted significantly increased numbers of activated microglia in the granule cell layer, hilus, CA1, and CA3 regions of the hippocampi of LH rats. Conversely, administering imipramine to LH rats for 7days produced a significant decrease in the number of activated microglia in the hilus, but not in the other examined regions. Nonetheless, there were no significant differences in the combined number of activated and non-activated microglia either in LH or LH+imipramine rats relative to control rats. In addition, treating the naïve rats with imipramine or fluvoxamine produced no discernible microglial changes. These data suggest that stress activates hippocampal microglia, while certain antidepressants decrease the number of activated microglia in the hilus, but not in other hippocampal regions. Therefore, the hilus represents a candidate target region for the antidepressant imipramine. Copyright Â© 2016 Elsevier Inc. All rights reserved.
Lack of promoter IV-driven BDNF transcription results in depression-like behavior.

PubMed

Sakata, K; Jin, L; Jha, S

2010-10-01

Transcription of Bdnf is controlled by multiple promoters, in which promoter IV contributes significantly to activity-dependent Bdnf transcription. We have generated promoter IV mutant mice [brain-derived neurotrophic factor (BDNF)-KIV] in which promoter IV-driven expression of BDNF is selectively disrupted by inserting a green fluorescent protein (GFP)-STOP cassette within the Bdnf exon IV locus. BDNF-KIV animals exhibited depression-like behavior as shown by the tail suspension test (TST), sucrose preference test (SPT) and learned helplessness test (LHT). In addition, BDNF-KIV mice showed reduced activity in the open field test (OFT) and reduced food intake in the novelty-suppressed feeding test (NSFT). The mutant mice did not display anxiety-like behavior in the light and dark box test and elevated plus maze tests. Interestingly, the mutant mice showed defective response inhibition in the passive avoidance test (PAT) even though their learning ability was intact when measured with the active avoidance test (AAT). These results suggest that promoter IV-dependent BDNF expression plays a critical role in the control of mood-related behaviors.

This study tested a parallel two-mediator model in which the relationship between dimensions of emotional intelligence and online gaming addiction are mediated by perceived helplessness and perceived self-efficacy, respectively. The sample included 931 male adolescents (mean age = 16.18 years, SD = 0.95) from southern China. Data on emotional intelligence (four dimensions, including self-management of emotion, social skills, empathy and utilization of emotions), perceived stress (two facets, including perceived self-efficacy and perceived helplessness) and online gaming addiction were collected, and bootstrap methods were used to test this parallel two-mediator model. Our findings revealed that perceived self-efficacy mediated the relationship between three dimensions of emotional intelligence (i.e., self-management, social skills, and empathy) and online gaming addiction, and perceived helplessness mediated the relationship between two dimensions of emotional intelligence (i.e., self-management and emotion utilization) and online gaming addiction. These findings underscore the importance of separating the four dimensions of emotional intelligence and two facets of perceived stress to understand the complex relationship between these factors and online gaming addiction.

Low response rate was witnessed with the present monoaminergic based antidepressants, urging a need for new therapeutic target identification. Accumulated evidences strongly suggest that mitochondrial deficit is implicated in major depression and 18kDa translocator protein (TSPO) plays an important role in regulating mitochondrial function. However the changes of TSPO and TSPO mediated mitophagy pathway in the depressive brain is unclear. In present study, a well validated animal model of depression, learned helplessness (LH), was employed to investigate the relevant changes. Significant behavioral changes were observed in the LH mice. Results showed that TSPO and other mitophagy related proteins, such as VDAC1, Pink1 and Beclin1 were significantly decreased by LH challenge. Moreover, KIFC2, relevant to the mitochondrial transport and Snap25, relevant to neurotransmitter vesicle release, were also obviously down-regulated in the LH mice, which further rendered supportive evidence for the existing mitochondrial dysfunction in LH mice. Present results demonstrated that LH induced depressive symptoms and affected TSPO-mediated mitophagy pathway, indicating a potential target candidate for depression treatment.

Shell, Duane F.; Soh, Leen-Kiat

2013-12-01

The goal of the present study was to utilize a profiling approach to understand differences in motivation and strategic self-regulation among post-secondary STEM students in major versus required non-major computer science courses. Participants were 233 students from required introductory computer science courses (194 men; 35 women; 4 unknown) at a large Midwestern state university. Cluster analysis identified five profiles: (1) a strategic profile of a highly motivated by-any-means good strategy user; (2) a knowledge-building profile of an intrinsically motivated autonomous, mastery-oriented student; (3) a surface learning profile of a utility motivated minimally engaged student; (4) an apathetic profile of an amotivational disengaged student; and (5) a learned helpless profile of a motivated but unable to effectively self-regulate student. Among CS majors and students in courses in their major field, the strategic and knowledge-building profiles were the most prevalent. Among non-CS majors and students in required non-major courses, the learned helpless, surface learning, and apathetic profiles were the most prevalent. Students in the strategic and knowledge-building profiles had significantly higher retention of computational thinking knowledge than students in other profiles. Students in the apathetic and surface learning profiles saw little instrumentality of the course for their future academic and career objectives. Findings show that students in STEM fields taking required computer science courses exhibit the same constellation of motivated strategic self-regulation profiles found in other post-secondary and K-12 settings.
Helplessness, mastery and the development of eating disorders: exploring the links between vulnerability and precipitating factors.

PubMed

Troop, N A

2012-12-01

Helplessness and mastery in childhood and in response to the events that trigger onset are implicated in the development of eating disorders. However, no studies have yet explored how these are linked and whether the effects are additive or mediated. Semi-structured interviews (Childhood Experience of Care and Abuse; Life Events and Difficulties Schedule; Coping Strategies Interview) were used to assess helplessness and mastery in childhood and in response to a provoking agent in 15 eating disordered and 19 non-eating disordered women. Helplessness and mastery in childhood were related to helplessness and mastery in response to the events and difficulties that triggered onset of the eating disorder. However, only the presence of helplessness and the lack of mastery in response to this provoking agent predicted onset. Helplessness and mastery are vulnerability and protective factors but only in those women who develop an eating disorder in the context of later life events. It is suggested that helplessness and mastery in childhood act via their influence on the adequacy of coping in response to later life events.

The relation between scoring for hopelessness/helplessness and the Montgomery-Asberg Depression Rating Scale (MADRS) in healthy study subjects (HSS) and in patients with benign breast disease (BBD) and breast cancer (BC) has not been compared in a prospective study. We, therefore, investigated hopelessness and helplessness scores versus the MADRS in 115 patients. In the Kuopio Breast Cancer Study, 115 women with breast symptoms were evaluated for hopelessness and helplessness, and for the MADRS before any diagnostic procedures were carried out. In the self-rating score (SRS), hopelessness/helplessness versus the MADRS were highly significantly positively correlated in the HSS, BBD and BC groups. In the SRS, the weighted kappa values for hopelessness/helplessness versus the MADRS in the HSS, BBD and BC groups were also statistically significant. There was also a significant positive correlation in the examiner-rating score (ERS) for hopelessness versus the MADRS in the HSS, BBD and BC groups and for helplessness versus the MADRS in the HSS, BBD and BC groups. The unweighted kappa values in the ERS for hopelessness versus the MADRS were statistically highly significant for the HSS, BBD and BC groups and those for helplessness versus the MADRS in the HSS and BBD groups were statistically significant. A new finding with clinical relevance in the present work is the agreement between hopelessness/helplessness scores and MADRS in the SRS and ERS. In the breast cancer diagnostic unit, the identification of hopeless/helpless persons is essential in suicide prevention and it is important to assess and treat hopelessness/helplessness even though an individual may report few depressive symptoms.

Camacho, Elizabeth M.; Verstappen, Suzanne M. M.; Chipping, Jacqueline

2013-01-01

Objectives. Cross-sectional studies have found that learned helplessness (LH) is associated with disease outcome in patients with RA. However, little is known about the longitudinal impact of LH. The aim of this study was to investigate whether LH is associated with future disease outcome (disability, pain and fatigue) and to investigate whether LH changes over time in patients with recent-onset inflammatory polyarthritis (IP), the broader group of conditions of which RA is the major constituent. Methods. Patients included in this investigation had been recruited to the Norfolk Arthritis Register, a primary-care-based inception cohort. LH was measured at baseline as patients’ total score on the Rheumatology Attitudes Index (RAI). A total of 443 patients completed the HAQ and visual analogue scales of pain and fatigue at baseline and after 2 years of follow-up. Results. Greater feelings of LH at baseline were associated with higher HAQ scores at follow-up [difference in HAQ score per 1-point increase in RAI score (β-coefficient) 0.02; 95% CI 0.01, 0.04]. Greater baseline LH was also associated with more pain (β-coefficient 1.0; 95% CI 0.4, 1.5) and more fatigue (β-coefficient 1.0; 95% CI 0.2, 1.4) at follow-up. LH was highly changeable during follow-up, with 87% of patients showing any change and 50% improving. Conclusion. Baseline LH independently predicted disability, pain and fatigue at follow-up. Half of patients reported fewer feelings of helplessness after 2 years of follow-up, suggesting that LH may potentially be a modifiable risk factor for disease outcome in IP and a target for intervention.

Depression of Excitatory Synapses onto Parvalbumin Interneurons in the Medial Prefrontal Cortex in Susceptibility to Stress

PubMed Central

Delevich, Kristen

2015-01-01

In response to extreme stress, individuals either show resilience or succumb to despair. The prefrontal cortex (PFC) is required for coping with stress, and PFC dysfunction has been implicated in stress-related mental disorders, including depression. Nevertheless, the mechanisms by which the PFC participates in stress responses remain unclear. Here, we investigate the role of parvalbumin (PV) interneurons in the medial PFC (mPFC) in shaping behavioral responses to stress induced by the learned helplessness procedure, in which animals are subjected to an unpredictable and inescapable stressor. PV interneurons in the mPFC were probed and manipulated in knock-in mice expressing the Cre recombinase under the endogenous parvalbumin promoter. Notably, we found that excitatory synaptic transmission onto these neurons was decreased in mice showing helplessness, a behavioral state that is thought to resemble features of human depression. Furthermore, selective suppression of PV interneurons in the mPFC using hM4Di, a DREADD (designer receptor exclusively activated by designer drug), promoted helplessness, indicating that activation of these neurons during stress promotes the establishment of resilient behavior. Our results reveal a cellular mechanism of mPFC dysfunction that may contribute to the emergence of maladaptive behavioral responses in the face of adverse life events. PMID:25698754
Targeting the BH3-interacting domain death agonist to develop mechanistically unique antidepressants

The BH3-interacting domain death agonist (Bid) is a pro-apoptotic member of the B-cell lymphoma-2 (Bcl-2) protein family. Previous studies have shown that stress reduces levels of Bcl-2 in brain regions implicated in the pathophysiology of mood disorders, whereas antidepressants and mood stabilizers increase Bcl-2 levels. The Bcl-2 protein family has an essential role in cellular resilience as well as synaptic and neuronal plasticity and may influence mood and affective behaviors. This study inhibited Bid in mice using two pharmacological antagonists (BI-11A7 and BI-2A7); the selective serotonin reuptake inhibitor citalopram was used as a positive control. These agents were studied in several well-known rodent models of depression—the forced swim test (FST), the tail suspension test (TST), and the learned helplessness (LH) paradigm—as well as in the female urine sniffing test (FUST), a measure of sex-related reward-seeking behavior. Citalopram and BI-11A7 both significantly reduced immobility time in the FST and TST and attenuated escape latencies in mice that underwent the LH paradigm. In the FUST, both agents significantly improved duration of female urine sniffing in mice that had developed helplessness. LH induction increased the activation of apoptosis-inducing factor (AIF), a caspase-independent cell death constituent activated by Bid, and mitochondrial AIF expression was attenuated by chronic BI-11A7 infusion. Taken together, the results suggest that functional perturbation of apoptotic proteins such as Bid and, alternatively, enhancement of Bcl-2 function, is a putative strategy for developing novel therapeutics for mood disorders.

Dorsal Medial Habenula Regulation of Mood-Related Behaviors and Primary Reinforcement by Tachykinin-Expressing Habenula Neurons

2016-01-01

Abstract Animal models have been developed to investigate aspects of stress, anxiety, and depression, but our understanding of the circuitry underlying these models remains incomplete. Prior studies of the habenula, a poorly understood nucleus in the dorsal diencephalon, suggest that projections to the medial habenula (MHb) regulate fear and anxiety responses, whereas the lateral habenula (LHb) is involved in the expression of learned helplessness, a model of depression. Tissue-specific deletion of the transcription factor Pou4f1 in the dorsal MHb (dMHb) results in a developmental lesion of this subnucleus. These dMHb-ablated mice show deficits in voluntary exercise, a possible correlate of depression. Here we explore the role of the dMHb in mood-related behaviors and intrinsic reinforcement. Lesions of the dMHb do not elicit changes in contextual conditioned fear. However, dMHb-lesioned mice exhibit shorter immobility time in the tail suspension test, another model of depression. dMHb-lesioned mice also display increased vulnerability to the induction of learned helplessness. However, this effect is not due specifically to the dMHb lesion, but appears to result from Pou4f1 haploinsufficiency elsewhere in the nervous system. Pou4f1 haploinsufficiency does not produce the other phenotypes associated with dMHb lesions. Using optogenetic intracranial self-stimulation, intrinsic reinforcement by the dMHb can be mapped to a specific population of neurokinin-expressing habenula neurons. Together, our data show that the dMHb is involved in the regulation of multiple mood-related behaviors, but also support the idea that these behaviors do not reflect a single functional pathway.

Istradefylline, an adenosine A2A receptor antagonist, improves motor function in animal models of Parkinson's disease (PD) and in patients with PD. In addition, some A2A antagonists exert antidepressant-like activity in rodent models of depression, such as the forced swim and the tail suspension tests. We have investigated the effect of istradefylline on depression-like behaviors using the rat learned helplessness (LH) model. Acute, as well as chronic, oral administration of istradefylline significantly improved the inescapable shock (IES)-induced escape deficit with a degree of efficacy comparable to chronic treatment with the tricyclic antidepressant desipramine and the selective serotonin (5-HT) reuptake inhibitor, fluoxetine. Both the A1/A2A receptor nonspecific antagonist theophylline and the moderately selective antagonist CGS15943, but not the A1 selective antagonist DPCPX, ameliorated the IES-induced escape deficit. The enhancement of escape response by istradefylline was reversed by a local injection of the A2A specific agonist CGS21680 either into the nucleus accumbens, the caudate-putamen, or the paraventricular nucleus of the hypothalamus, but not by the A1 specific agonist R-PIA into the nucleus accumbens. Moreover, neither the 5-HT2A/2C receptor antagonist methysergide or the adrenergic α 2 antagonist yohimbine, nor the β-adrenergic antagonist propranolol, affected the improvement of escape response induced by istradefylline. Istradefylline exerts antidepressant-like effects via modulation of A2A receptor activity which is independent of monoaminergic transmission in the brain. Istradefylline may represent a novel treatment option for depression in PD as well as for the motor symptoms.

Effects of repeated deep brain stimulation on depressive- and anxiety-like behavior in rats: comparing entopeduncular and subthalamic nuclei.

Deep brain stimulation (DBS) of the subthalamic nucleus (STN) or internal globus pallidus (GPi) has been routinely used for the treatment of some movement disorders. However, DBS may be associated with adverse psychiatric effects, such as depression, anxiety and impulsivity. To compare DBS applied to the entopeduncular nucleus (EPN; the rodent homolog of the GPi) and STN in terms of their effects on depressive- and anxiety-like behavior in rats. DBS was applied for 21 days (4 h a day) to either the STN or EPN. Rats then underwent behavioral testing on learned helplessness and elevated plus maze tasks before being sacrificed for brain analyses of zif268, BDNF and trkB mRNA as well as BDNF protein levels. Repeated DBS of the STN, but not of the EPN, led to impaired performance in the learned helplessness task, suggesting that STN-DBS induces or potentiates depressive-like behavior. There was no effect of DBS on elevated plus maze or on open field behavior. Repeated STN-DBS, but not EPN-DBS, led to decreased levels of BDNF and trkB mRNA in hippocampus. Acute stimulation of the STN or EPN resulted in similar changes in zif268 levels in several brain areas, except for the raphe where decreases were seen only after STB-DBS. Together these results indicate that the effects of STN- and EPN-DBS differ in behavioral and neurochemical respects. Results further suggest that the EPN may be a preferable target for clinical DBS when psychiatric side effects are considered insofar as it may be associated with a lower incidence of depressive-like behavior than the STN.

To examine the effect of outcome expectation for exercise (OEE), helplessness, and literacy on arthritis outcomes in 2 community-based lifestyle randomized controlled trials (RCTs) conducted in urban and rural communities with older adults with arthritis. Data from 391 participants in 2 RCTs were combined to examine associations of 2 psychosocial variables: helplessness and OEE, and literacy with arthritis outcomes. Arthritis outcomes namely, the Health Assessment Questionnaire-Disability Index (HAQ-DI) and arthritis symptoms pain, fatigue and stiffness Visual Analogue Scales (VAS), were measured at baseline and at the end of the interventions. Complete baseline and post-intervention data were analyzed using STATA version 9. Disability after intervention was not predicted by helplessness, literacy, or OEE in the adjusted model. Arthritis symptoms after the intervention were all significantly predicted by helplessness at various magnitudes in adjusted models, but OEE and literacy were not significant predictors. When literacy, helplessness, and OEE were examined as predictors of arthritis outcomes in intervention trials, they did not predict disability. However, helplessness predicted symptoms of pain, fatigue, and stiffness, but literacy did not predict symptoms. Future sustainable interventions may include self-management components that address decreasing helplessness to improve arthritis outcomes. (c) 2009 Elsevier Ireland Ltd. All rights reserved.

2007-01-01

Based on the fear-avoidance and helplessness models, the relative contribution of fear of pain, avoidance behavior, worrying, and helplessness were examined in relation to fluctuations in functional disability in chronic-pain patients. A cohort of 181 chronic-pain patients first completed various questionnaires and kept a 7-day pain journal during a standard 3-month waiting-list period prior to their scheduled treatment at an Interdisciplinary Pain Centre and did so again immediately preceding the intervention. At baseline, fear of pain, avoidance behavior, and helplessness all predicted functional disability after 3 months. Stepwise regression analyses showed avoidance behavior to be the strongest predictor of change in functional disability followed by helplessness, thus both ahead of fear of pain. The current findings support the roles of both fear-avoidance factors and helplessness in the functional disability in chronic-pain patients awaiting treatment but revealed a central role for avoidance behavior.

The relation between hopelessness/helplessness versus the Beck Depression Inventory (BDI) in healthy study subjects (HSS) and in patients with benign breast disease (BBD) and breast cancer (BC) has not been compared in a prospective study before. We, therefore, investigated hopelessness and helplessness versus the BDI in 115 patients. In the Kuopio Breast Cancer Study, 115 women with breast symptoms were evaluated for hopelessness and helplessness versus the BDI before any diagnostic procedures were carried out. In the self-rating score (SRS), the hopelessness and the helplessness versus the BDI were highly significantly positively correlated in the HSS, BBD and BC groups. In the SRS, the weighted kappa values for hopelessness and helplessness versus the BDI in the HSS, BBD and BC groups were also statistically significant. There was also a significant positive correlation in the examiner-rating score (ERS) in the hopelessness versus the BDI in the BBD and BC groups and in the ERS in helplessness versus the BDI in the HSS and BBD groups. The unweighted kappa values in the ERS for hopelessness versus the BDI in the HSS and BBD groups were statistically highly significant and the unweighted kappa values in the ERS for helplessness versus the BDI in the BBD and BC groups were statistically significant. The results of this study support a powerful link between hopelessness and helplessness versus BDI in the self-rating and examiner-rating. This finding is of clinical importance since, in the breast cancer diagnostic unit, the patients with hopelessness/helplessness characteristics and high BDI score might be associated with a difficulty and delay in reaching BC diagnosis.

In neuropsychiatry, animal studies demonstrating causal effects of environmental manipulations relevant to human aetiology on behaviours relevant to human psychopathologies are valuable. Such valid models can improve understanding of aetio-pathophysiology and preclinical discovery and development of new treatments. In depression, specific uncontrollable stressful life events are major aetiological factors, and subsequent generalized increases in fearfulness, helplessness and fatigue are core symptoms or features. Here we exposed adult male C57BL/6 mice to 15-day psychosocial stress with loss of social control but minimal physical wounding. One cohort was assessed in a 3-day test paradigm of motor activity, fear conditioning and 2-way avoid-escape behaviour on days 16-18, and a second cohort was assessed in a treadmill fatigue paradigm on days 19 and 29, followed by the 3-day paradigm on days 30-32. All tests used a physical aversive stimulus, namely mild, brief electroshocks. Socially stressed mice displayed decreased motor activity, increased fear acquisition, decreased 2-way avoid-escape responding (increased helplessness) and increased fatigue. They also displayed increased plasma TNF and spleen hypertrophy, and adrenal hypertrophy without hyper-corticoidism. In a third cohort, psychosocial stress effects on brain gene expression were assessed using next generation sequencing. Gene expression was altered in pathways of inflammation and G-protein coupled receptors in prefrontal cortex and amygdala; in the latter, expression of genes important in dopamine function were de-regulated including down-regulated Drd2, Adora2a and Darpp-32. This model can be applied to identify targets for treating psychopathologies such as helplessness or fatigue, and to screen compounds/biologics developed to act at these targets.

2006-01-01

The goal of this study was to examine the relative contribution of helplessness, fear of pain, and passive pain-coping to pain level, disability, and depression in chronic pain patients attending an interdisciplinary pain center. One hundred sixty-nine chronic pain patients who had entered treatment at an interdisciplinary pain center completed various questionnaires and a pain diary. Helplessness, fear of pain, and passive pain-coping strategies were all related to the pain level, disability, and depression. When comparing the contribution of the predictors in multiple regression analyses, helplessness was the only significant predictor for pain level. Helplessness and the passive behavioral pain-coping strategies of resting significantly predicted disability. The passive cognitive pain-coping strategy of worrying significantly predicted depression. These findings indicate a role for helplessness and passive pain-coping in chronic pain patients and suggest that both may be relevant in the treatment of pain level, disability, and/or depression.

Resisting temptation: a psychological analysis.

Hodgson, R J

1989-03-01

It is proposed that self control involves several related processes including vivid awareness of future consequences, overcoming learned helplessness and tunnel vision, developing commitment and accepting anxiety/frustration. Facing up to temptation and resisting the compulsive urge is considered to be a crucial therapeutic experience. Evidence is presented to support the view that cue exposure should therefore be a central component of treatments for compulsions and addictions.
Depression of excitatory synapses onto parvalbumin interneurons in the medial prefrontal cortex in susceptibility to stress.

Perova, Zinaida; Delevich, Kristen; Li, Bo

2015-02-18

In response to extreme stress, individuals either show resilience or succumb to despair. The prefrontal cortex (PFC) is required for coping with stress, and PFC dysfunction has been implicated in stress-related mental disorders, including depression. Nevertheless, the mechanisms by which the PFC participates in stress responses remain unclear. Here, we investigate the role of parvalbumin (PV) interneurons in the medial PFC (mPFC) in shaping behavioral responses to stress induced by the learned helplessness procedure, in which animals are subjected to an unpredictable and inescapable stressor. PV interneurons in the mPFC were probed and manipulated in knock-in mice expressing the Cre recombinase under the endogenous parvalbumin promoter. Notably, we found that excitatory synaptic transmission onto these neurons was decreased in mice showing helplessness, a behavioral state that is thought to resemble features of human depression. Furthermore, selective suppression of PV interneurons in the mPFC using hM4Di, a DREADD (designer receptor exclusively activated by designer drug), promoted helplessness, indicating that activation of these neurons during stress promotes the establishment of resilient behavior. Our results reveal a cellular mechanism of mPFC dysfunction that may contribute to the emergence of maladaptive behavioral responses in the face of adverse life events.

[Influence of stress on learning and memory].

PubMed

Ukai, M

2000-08-01

This paper describes the influence of stress on learning and memory. The mice receiving inescapable electroshock fail to perform the active conditioned avoidance response of lever-pressing. This is called learned helplessness, which is ameliorated by treatment with antidepressants including one of the selective serotonin reuptake inhibitors (SSRIs). It is of particular interest that posttraumatic stress disease (PTSD) accompanied by memory impairment could be improved by treatment with SSRIs. The different kinds of stress including ischemia, footshock, psychological stress, and forced swimming influence learning and memory as indexed by spontaneous alternation performance as well as passive avoidance learning. In addition, a variety of stresses influence the activity of hormones and neurotransmitters like monoamines, neuropeptides, and excitatory amino acids resulting in changes in learning and memory. Finally, the accumulation of data is necessary to clarify the exact mechanism of stress on learning and memory.
[Effect of previous experience in reacting to a danger signal on "open field" behavior in the rat].

Poltyreva, T E; Petrov, E S

1983-01-01

Modification of rats behaviour in an "hopen field" test was investigated, induced by an acoustic stimulus, previously subjected to conditioning in a shuttle chamber in experiments with possibility and impossibility of avoidance from electrical shock. It has been established that presentation of a stimulus having the meaning of a danger signal, in a new situation, significantly suppresses investigating behaviour of rats, whereas the stimulus which had not been subjected to conditioning exerts no marked effect on behaviour. The greatest suppression was observed in rats with "learned helplessness". This fact suggests that the degree of suppression of the behaviour in an open field in response to a danger signal, depends on the animal's previous experience in reacting to this signal.

2015-06-01

The relation between suicidal ideation versus hopelessness/helplessness in healthy study subjects (HSS) and in patients with benign breast disease (BBD) and breast cancer (BC) has not been compared to date in a prospective study. We, therefore, investigated suicidal ideation versus hopelessness/helplessness in 115 patients. In the Kuopio Breast Cancer Study, 115 women with breast symptoms were evaluated for hopelessness and helplessness versus suicidal/pessimistic thoughts before any diagnostic procedures were carried-out. In the self-rating score (SRS), hopelessness and the helplessness versus pessimistic thoughts were significantly correlated in the HSS, BBD and BC groups. In the SRS, the weighted kappa-values for hopelessness versus pessimistic thoughts in the BBD group were also statistically significant. There was also a significant positive correlation in the examiner-rating score (ERS) in the hopelessness versus pessimistic thoughts in the HSS, BBD and BC groups, as well as in the ERS, in the helplessness versus pessimistic thoughts in the HSS and BBD groups. In SRS, the hopelessness and the helplessness versus suicidal thoughts were significantly correlated in the HSS, BBD and BC groups. There was also a significant positive correlation in the ERS in the hopelessness versus suicidal thoughts in the HSS, BBD and BC groups, as well as in the ERS, in the helplessness versus suicidal thoughts in the BBD group. A new finding with clinical relevance in the present work is the agreement between hopelessness/helplessness versus suicidal/pessimistic thoughts in the self-rating and examiner-rating. In the breast cancer diagnostic Unit, the identification of suicidal ideation is essential in suicide prevention and it is important to assess and treat depression even though a subject reports little suicidal ideation.

Exposure to Unsolvable Anagrams Impairs Performance on the Iowa Gambling Task

Starcke, Katrin; Agorku, Janet D.; Brand, Matthias

2017-01-01

Recent research indicates that external manipulations, such as stress or mood induction, can affect decision-making abilities. In the current study, we investigated whether the exposure to an unsolvable task affected subsequent performance on the Iowa Gambling Task. Participants were randomly assigned to a condition in which they were exposed to unsolvable anagrams (n = 20), or a condition in which they worked on solvable anagrams (n = 22). Afterwards, all participants played the Iowa Gambling Task, a prominent task that measures decision making under uncertain conditions with no explicit rules for gains and losses. In this task, it is essential to process feedback from previous decisions. The results demonstrated that participants who worked on unsolvable anagrams made more disadvantageous decisions on the Iowa Gambling Task than the other participants. In addition, a significant gender effect was observed: Males who worked on unsolvable anagrams made a more disadvantageous decisions than the other male participants. Females who worked on unsolvable anagrams also made more disadvantageous decision than the other female participants, but differences were small and not significant. We conclude that the exposure to unsolvable anagrams induced the experience of uncontrollability which can elicit stress and learned helplessness. Stress and learned helplessness might have reduced the ability to learn from the given feedback, particularly in male participants. We assume that in real life, uncontrollable challenges that last longer than a single experimental manipulation can affect decision making severely, at least in males. PMID:28642693
Emotional response in dopamine D2L receptor-deficient mice

Hranilovic, Dubravka; Bucan, Maja; Wang, Yanyan

2008-01-01

The dopamine D2 receptor (D2R) system has been implicated in emotional processing which is often impaired in neuropsychiatric disorders. The long (D2L) and the short (D2S) isoforms of D2R are generated by alternative splicing of the same gene. To study differential roles of the two D2R isoforms, D2L-deficient mice (D2L−/−) expressing functional D2S were previously generated. In this study the contribution of D2L isoform to emotional response was investigated by examining behaviors that reflect emotionality (exploratory behavior, anxiety-like behavior and learned helplessness) in D2L−/− and (wild-type) WT mice. While the thigmotactic, locomotor and general components of anxiety in zero maze did not differ among the genotypes, D2L−/− mice displayed significantly lower level of exploration in a hole board and zero maze, and significantly higher increase in latency to escape from a foot shock after the learned helplessness training, compared with WT mice. These results suggest that D2L may play a more prominent role than D2S in mediating emotional response, such as behavioral reactions to novelty and inescapable stress. Our findings contribute to a better understanding of the molecular and cellular mechanisms underlying emotional responses. PMID:18835570

Youth with obsessive-compulsive disorder (OCD) are at risk of experiencing comorbid psychiatric conditions, such as depression and anxiety. Studies of Chinese adolescents with OCD are limited. The aim of this study was to investigate the association of depression, anxiety, and helplessness with the occurrence of OCD in Chinese adolescents. This study consisted of two stages. The first stage used a cross-sectional design involving a stratified clustered non-clinical sample of 3174 secondary school students. A clinical interview procedure was then employed to diagnose OCD in students who had a Leyton 'yes' score of 15 or above. The second phase used a case-control study design to examine the relationship of OCD to depression, anxiety and helplessness in a matched sample of 288 adolescents with clinically diagnosed OCD and 246 students without OCD. Helplessness, depression and anxiety scores were directly associated with the probability of OCD caseness. Canonical correlation analysis indicated that the OCD correlated significantly with depression, anxiety, and helplessness. Cluster analysis further indicated that the degree of the OCD is also associated with severity of depression and anxiety, and the level of helplessness. These findings suggest that depression, anxiety and helplessness are important correlates of OCD in Chinese adolescents. Future studies using longitudinal and prospective designs are required to confirm these relationships as causal. Copyright © 2014 Elsevier B.V. All rights reserved.
A narrative analysis of helplessness in depression.

PubMed

Vanheule, Stijn; Hauser, Stuart T

2008-12-01

The transcripts of semistructured clinical interviews with forty psychiatrically hospitalized adolescents were subjected to narrative analysis in an effort to map the logic of their explanations as they spontaneously talked about helplessness experiences, and to determine how helplessness is embedded in broader story lines. Three types of narrative composition were discerned, and are discussed by means of excerpts from the interviews. In a first and predominant type of narrative, a disturbing confrontation with another is pivotal: the other's intentions are obscure; this frightens the narrator, who does not know what to do. Helplessness arises as a direct result of not knowing how to manage the "unbearable riddle" of the other's intentions. In the second, more marginal type of narrative, helplessness is embedded in an account of emptiness and boredom. The protagonist relates enduring experiences of emptiness due to loss and the suffering consequent on it. In the third, also more marginal type of narrative, helplessness is framed in a context of failure: the protagonist adheres to strict standards, feels he or she has fallen short, and concludes that he or she is a failure. Only the first type of narrative is significantly related to the psychiatric diagnoses of mood disorder and major depression.
Different types of avoidance behavior in rats produce dissociable post-training changes in sleep.

Avoidance learning affects post-training sleep, and post-training sleep deprivation impairs performance. However, not all rats learn to make avoidance responses, and some rats fail to escape; a definitive behavior of learned helplessness, a model of depression. This study investigated the changes in sleep associated with different behaviors adopted following avoidance training. Rats (n=53) were trained for 100 trials over 2 days (50 trials/day), followed by 23-24 h of post-training polysomnography, then re-tested (25 trials). At re-test, rats were categorized into: 1) Active Avoiders (AA; n=22), 2), Non-learning (NL; n=21), or 3) Escape Failures (EF; n=10). AA rats increased avoidances over days, whereas the NL and EF groups did not. EF rats increased escape failures over days, whereas the NL and AA rats did not. EF rats had increased rapid eye movement (REM) sleep in the first 4h on training day 1. They also had increased non-REM sleep in the first 4h and last 4h on both training days. AA rats had increased REM sleep 13-20 h post-training. The type of behavioral strategy adopted throughout training is associated with a unique pattern of changes in post-training sleep. Training-dependent changes in post-acquisition sleep may reflect distinct processes involved in the consolidation of these different memory traces. Copyright Â© 2010 Elsevier Inc.

Castaways: addressing hostility and helplessness in severely lonely adults.

PubMed

Loboprabhu, Sheila; Molinari, Victor; Asghar-Ali, Ali Abbas

2015-03-01

Hostility and helplessness are recurrent themes in severely lonely adults, and they can be both causes and effects of subjective feelings of loneliness. Since many lonely patients report a history of abuse, hostile and helpless states of mind may reflect identification with hostile (aggressor) or helpless (passive) attachment figures. Hostile intrusiveness and helpless withdrawal by the parent are 2 distinct patterns of parent-child misattunement that can lead to infant disorganization via disrupted emotional communication and to loneliness later in life. Anxious-ambivalent lonely older adults tend to exhibit hyperactivating hostile behaviors (to deal with a core sense of powerlessness), whereas those with fearful-avoidant attachment styles exhibit deactivating helpless behaviors (to deflect intense underlying feelings of rage). Based on this model, we outline different treatment approaches for lonely persons with different attachment styles by describing the successful treatment of two severely lonely, suicidal veterans. We describe an approach to treating hostile and helpless behaviors in lonely patients, using validation, mentalization, reality orientation, and socialization. Validation provides a sense of safety and rapport. Mentalization allows the lonely individual to better appreciate his or her own mental processes and those of others. Reality orientation provides feedback to lonely individuals on whether their perceptions are accurate and reality-based and helps them appreciate the consequences their behavior may have for self and others. Finally, socialization reduces disenfranchisement by teaching/re-teaching individuals social skills that may have become impaired by prolonged isolation.
Learning During Stressful Times

PubMed Central

Shors, Tracey J.

2012-01-01

Stressful life events can have profound effects on our cognitive and motor abilities, from those that could be construed as adaptive to those not so. In this review, I discuss the general notion that acute stressful experience necessarily impairs our abilities to learn and remember. The effects of stress on operant conditioning, that is, learned helplessness, as well as those on classical conditioning procedures are discussed in the context of performance and adaptation. Studies indicating sex differences in learning during stressful times are discussed, as are those attributing different responses to the existence of multiple memory systems and nonlinear relationships. The intent of this review is to highlight the apparent plasticity of the stress response, how it might have evolved to affect both performance and learning processes, and the potential problems with interpreting stress effects on learning as either good or bad. An appreciation for its plasticity may provide new avenues for investigating its underlying neuronal mechanisms. PMID:15054128

Using a sample of 69 undergraduates, scales were devised to measure helplessness, hopelessness, and haplessness and shown to have good reliability. Briefer scales were also developed whose scores were independent of one another in a factor analysis. Scores for 19 male and 50 female undergraduates on the 4-item scales of Helplessness and Hopelessness were associated with two different measures of depression, but scores on Hopelessness provided the stronger correlate.

Compulsory drug detention is the most frequent way to control drug use in China; however, it has often been criticized. This qualitative study aimed to investigate abstinence self-efficacy and its sources of drug users in a compulsory male drug detention center in Shanghai, China, and the attitudes of the drug users to this form of rehabilitation. Thirty-six participants were interviewed (semi-structured, in depth) about their history of drug use and rehabilitation, self-evaluation of addiction, motivations to abstain, plans for the future and attitudes toward rehabilitation. A thematic analysis was undertaken of the transcripts with responses to interview questions being coded for content. Two main types of self-efficacy were found - "overconfidence" (n = 16) and "helplessness" (n = 17). Overconfident participants underestimated their levels of addiction, overestimated their self-control and held external motivations and attributions. In contrast, helpless participants overestimated their levels of addiction, underestimated their self-control and had internal motivations and attributions. Compared to overconfident participants, helpless participants had more relapse history, and were more inclined to interpret relapse as a failure and attribute relapse to themselves. More helpless participants were abandoned by their family members, and received blame from the family members instead of encouragement, but their family members motivated them to abstain. Helpless participants experienced more negative emotions and had worse physical status. They said compulsory detention was a strong support for them and was the most effective way to abstain; while overconfident participants said compulsory detention was not necessary and not useful. It is important to increase the motivation of overconfident drug users and the perceived control of helpless drug users. Compulsory drug detention has strengths in supporting drug users who feel helpless to resist drug use. Adjustments and improvements of compulsory drug detention are suggested.

Clinical observations suggest that negative affects such as helplessness/hopelessness (HE/HO) may induce autonomic duration; affects were assessed for every move after reconstruction of the games. In all games compiled, 18 situation of intense confidence/optimism and 20 of intense helplessness/hopelessness were observed. Intense affects of HE/HO were associated with decreasing HF-HRV (Fisher exact test, p =.003), increasing "nervousness" (p =.0005), decreasing "optimism" (p =.0005), and decreasing "calmness" (p =.0005). Investigation of championship chess game players with an ELO strength > or = 2300 in a natural field setting revealed increasing HE/HO being associated with reduced HF-HRV suggestive of vagal withdrawal. Thus, our data may help link negative mood states, autonomic nervous system disturbances, and cardiac events.

To test the effects of a brief psychosocial intervention using CD-ROM (BPIC) on psychosocial (fighting spirit, helplessness or hopelessness, anxiety, and depression) and behavioral (self-care behaviors) outcomes in patients with cancer receiving adjuvant therapy. Quasi-experimental. A comprehensive cancer center in Seoul, South Korea. 71 patients undergoing adjuvant therapy. The study participants were assigned to either BPIC or a control group. The experimental group underwent a two-week psychosocial intervention via CD-ROM, booklet, and telephone counseling. Fighting spirit, helplessness or hopelessness, anxiety, depression, and self-care behaviors. After BPIC, the experimental group showed significantly higher scores than the control group for fighting spirit (p = 0.005) and self-care behaviors (p < 0.001). However, the groups showed no significant differences in helplessness or hopelessness (p = 0.42), anxiety (p = 0.279), and depression (p = 0.068). BPIC use improved fighting spirit and self-care behaviors in study participants. The results partially support the effectiveness of BPIC for adaptation among patients with cancer receiving adjuvant therapy. A brief psychosocial intervention using multimedia can be used effectively in clinical oncology settings to accelerate adaptation among patients with cancer in the adjuvant phase.

Eliminating the controllability of a noxious stimulus may induce a learned helplessness (LH) that resembles aspects of depression and post-traumatic stress disorder (PTSD). This study examined whether repetitive transcranial magnetic stimulation (rTMS) of the left dorsolateral prefrontal cortex (DLPFC) promotes resilience in an aversive stimulus model of LH. All 55 participants were told that an undisclosed sequence of button presses would terminate an aversive stimulus on their forearm. In truth, only half had control (+C). The other half had no control (-C). All participants received real (R) or sham (S) left DLPFC rTMS during the paradigm (+C/R, -C/S,+C/S,-C/R). We evaluated the cognitive effects of LH using an anagram task. The LH paradigm successfully reduced perceived control in the -C groups. As predicted, the +C/R and +C/S groups tended to give up less quickly and take less time to solve each anagram than did the -C/S group. Superior anagram performance in the -C/R group approached statistical significance. Our preliminary results suggest that manipulating the controllability of an aversive stimulus may induce an LH effect that manifests as impaired anagram performance. Further research is needed to refine this model and determine if DLPFC rTMS mitigates any LH effects. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.
Could implantable cardioverter defibrillators provide a human model supporting the learned helplessness theory of depression?

PubMed

Goodman, M; Hess, B

1999-01-01

Affective symptoms were examined retrospectively in 25 patients following placement of implantable cardioverter defibrillators (ICD) which can produce intermittent shocks without warning in response to cardiac ventricular arrhythmias. The number of ICD random, uncontrollable discharge shocks and pre-ICD history of psychological distress (i.e., depression and/or anxiety) were documented in all patients using a demographics questionnaire and a standardized behavioral/psychological symptoms questionnaire (i.e., Symptom Checklist-90 Revised). ICD patients were dichotomized into two groups: those without a history of psychological distress prior to ICD (n = 18) and those with a history of psychological distress prior to ICD (n = 7). In ICD patients without a prior history, results indicated that quantity of ICD discharge shocks was significantly predictive of current reported depression (r = 0.45, p = 0.03) and current reported anxiety (r = 0.51, p = 0.02). Conversely, in patients with a reported history of psychological distress, there was no significant relationship found between quantity of discharge shocks and current reported depression or anxiety. This study may provide evidence in support of a human model of learned helplessness in that it supports the notion that exposure to an unavoidable and inescapable aversive stimulus was found to be related to patients' reported depression. Further studies may wish to prospectively consider a larger sample as well as a more comprehensive assessment of premorbid psychological symptoms.

Hopelessness, helplessness, and powerlessness have been identified as phenomena of concern to psychiatric nursing practice by an American Nurses' Association (ANA) task force. These concepts, however, have not been clearly distinguished from each other. The resulting lack of clarity decreases the usefulness of nursing diagnoses in directing strategies for intervention. The purpose of this article is to differentiate the phenomena of hopelessness, helplessness, and powerlessness using Erik Erikson's "Roots of virtue" as a conceptual framework. The relationship between the frustration of early childhood tasks and later adult response patterns is discussed. Clinical examples illustrate that knowledge of childhood issues guides the formulation of therapeutic goals and interventions to address the experience of hopelessness, helplessness, and powerlessness.

Powerlessness and helplessness have been very little studied. The aims of this study were (1) to describe what characterise such experiences and the meaning of them to next of kin of cancer patients in advanced palliative home care and (2) to make quantifications. The study design was cross-sectional and targeted next of kin during ongoing palliative home care and next of kin of patients who had died 3-9 months earlier; 233 next of kin responded (response rate 72%) to a postal questionnaire with both Likert-type and open-ended questions. The text responses were analysed with a combined qualitative and quantitative content analysis. Thirty-six percent of respondents stated that they had experienced powerlessness and/or helplessness every day or several times per week, whereas 33% had never had this experience during the palliative home care period. Powerlessness and helplessness concerned next of kin's perception of the patient's suffering, of the patient's fading away and the next of kin's own feelings of insufficiency and resulted in both physical and psychological symptoms, such as muscle tension, headache, loss of appetite, anxiety and depression. In addition, powerlessness and helplessness concerned also a deeper meaning with existential and social aspects, such as feelings of guilt, anger and loneliness. The main findings provide tools for the practitioner to identify situations contributing to next of kin's sense of powerlessness and helplessness. The findings are discussed in relation to the concepts of symptom control, communication of awareness and humans' search for action.
[Predictors of fighting spirit or helplessness/hopelessness in people with cancer].

This study was done to identify predictors of the fighting spirit or helplessness/hopelessness in the patients' mental adjustment to cancer. Cancer patients' characteristics like performance status, metastasis and duration of diagnosis with demographic factors, spiritual support and social support were used as predictors of a fighting spirit or helplessness/hopelessness. A total of 124 ambulatory cancer patients completed the Mental Adjustment to Cancer (MAC) scale and responded in a structured instrument about their characteristics, spiritual and social support. The results of multiple regression analysis revealed that confidence in the supporter (R(2)=.114, p=.000), duration of cancer diagnosis (R(2)=.041, p=.000) and faith (R(2)=.030, p=.000) were predictive of a fighting spirit (R(2)=.185, p=.000); whereas, education (R(2)=.074, p=.001), performance status (R(2)=.055, p=.000), satisfaction with social support (R(2)=.046, p=.000), and metastasis (R(2)=.037, p=.000) were predictive of helplessness/hopelessness (R(2)=.202, p=.000). Social support, spiritual support and disease related factors like metastasis, performance status, and duration of cancer diagnosis need to be considered in a psychosocial nursing intervention for a fighting spirit or helplessness/hopelessness.
When Patients and Their Families Feel Like Hostages to Health Care.

Patients are often reluctant to assert their interests in the presence of clinicians, whom they see as experts. The higher the stakes of a health decision, the more entrenched the socially sanctioned roles of patient and clinician can become. As a result, many patients are susceptible to "hostage bargaining syndrome" (HBS), whereby they behave as if negotiating for their health from a position of fear and confusion. It may manifest as understating a concern, asking for less than what is desired or needed, or even remaining silent against one's better judgment. When HBS persists and escalates, a patient may succumb to learned helplessness, making his or her authentic involvement in shared decision making almost impossible. To subvert HBS and prevent learned helplessness, clinicians must aim to be sensitive to the power imbalance inherent in the clinician-patient relationship. They should then actively and mindfully pursue shared decision making by helping patients trust that it is safe to communicate their concerns and priorities, ask questions about the available clinical options, and contribute knowledge of self to clinical decisions about their care. Hostage bargaining syndrome is an insidious psychosocial dynamic that can compromise quality of care, but clinicians often have the power to arrest it and reverse it by appreciating, paradoxically, how patients' perceptions of their power as experts play a central role in the care they provide.

Depression is a highly heterogeneous disorder presumably caused by a combination of several factors ultimately causing the pathological condition. The genetic liability model of depression is likely to be of polygenic heterogeneity. miRNAs can regulate multiple genes simultaneously and therefore are candidates that align with this model. The habenula has been linked to depression in both clinical and animal studies, shifting interest towards this region as a neural substrate in depression. The goal of the present study was to search for alterations in miRNA expression levels in the medial and lateral habenula of rats exposed to the learned helplessness (LH) rat model of depression. Ten miRNAs showed significant alterations associating with their response to the LH paradigm. Of these, six and four miRNAs were significantly regulated in the MHb and LHb, respectively. In the MHb we identified miR-490, miR-291a-3p, MiR-467a, miR-216a, miR-18b, and miR-302a. In the LHb miR-543, miR-367, miR-467c, and miR-760-5p were significantly regulated. A target gene analysis showed that several of the target genes are involved in MAPK signaling, neutrophin signaling, and ErbB signaling, indicating that neurotransmission is affected in the habenula as a consequence of exposure to the LH paradigm.

Adult neurogenesis is reduced in the dorsal hippocampus of rats displaying learned helplessness behavior.

PubMed

Ho, Y C; Wang, S

Clinical and preclinical studies suggest that the hippocampus has a role in the pathophysiology of major depression. In the learned helplessness (LH) animal model of depression after inescapable shocks (ISs) animals that display LH behavior have reduced cell proliferation in the hippocampus; this effect can be reversed by antidepressant treatment. Using this model, we compared rats that displayed LH behavior and rats that did not show LH behavior (NoLH) after ISs to determine whether reduced hippocampal cell proliferation is associated with the manifestation of LH behavior or is a general response to stress. Specifically, we examined cell proliferation, neurogenesis, and synaptic function in dorsal and ventral hippocampus of LH and NoLH animals and control rats that were not shocked. The LH rats had showed reduced cell proliferation, neurogenesis, and synaptic transmission in the dorsal hippocampus, whereas no changes were seen in the ventral hippocampus. These changes were not observed in the NoLH animals. In a group of NoLH rats that received the same amount of electrical shock as the LH rats to control for the unequal shocks received in these two groups, we observed changes in Ki-67(+) cells associated with acute stress. We conclude that reduced hippocampal cell proliferation and neurogenesis are associated with the manifestation of LH behavior and that the dorsal hippocampus is the most affected area.

Early life adversity (ELA) increases the risk of depression during adolescence that may result from a decline in parvalbumin (PVB) secondary to increased neuroinflammation. In this study, we investigated depressive-like behavior following exposure to two different types of stressors that are relevant for their developmental period: 1) chronic ELA (maternal separation; MS) and 2) an acute emotional stressor during adolescence (witnessing their peers receive multiple shocks; WIT), and their interaction. We also determined whether reducing inflammation by cyclooxygenase-2 (COX-2) inhibition would prevent the onset of depressive-like behavior. Female Sprague-Dawley rat pups underwent MS for four-hours/day or received typical care (CON) between postnatal days (P) 2 and P20. A COX-2 inhibitor (COX-2I) or vehicle was administered every other day between P30 and P38. Subjects were tested for learned helplessness to assess depressive-like behavior at P40 (adolescence). MS females demonstrated increased escape latency and decreased PVB in the prefrontal cortex (PFC) and dorsal raphe that were attenuated by COX-2I intervention. Helplessness was also associated with an increase in D2 receptors in the accumbens. In contrast, WIT elevated escape latency in CON, but reduced latency in MS females. Furthermore, COX-2I intervention decreased escape latency in both CON and MS after WIT. WIT reduced PVB levels in the basolateral amygdala and increased PFC levels to CON levels. Our data suggest that decreased PVB in the PFC is important for the expression of depressive-like behavior and suggest that COX-2I intervention may provide a novel prevention for depression.

Survey data from a representative sample of 1005 households in the UK coastal city of Portsmouth are examined to discern commonalities and contrasts in their assessment of actions to address the related environmental threats of climate change and flooding. The city of Portsmouth is at risk of inundation from rising sea levels and the city has recent experience of flooding. A simple local and global public good framework is used to organize the understanding of reported attitudes and their determinants. The findings show that it is not always the same individuals who express concern about both climate change and flooding. Investigation into perceptions of helplessness in tackling climate change indicates that individuals more often perceived themselves to be helpless in tackling climate but perceived local collective action to be more effective. Individuals considered local collective action to be more effective in tackling climate change. Perceptions of individual helplessness are in turn related to reported concern. Several socioeconomic characteristics of individuals are shown to be useful in explaining the determinants of concern and perceptions of helplessness among respondents. As other cities face climate change-related challenges, the empirical findings, based upon attitudes from an alert urban population, are informative to policy design.

Fancy Citrus, Feel Good: Positive Judgment of Citrus Odor, but Not the Odor Itself, Is Associated with Elevated Mood during Experienced Helplessness

Aromatherapy claims that citrus essential oils exert mood lifting effects. Controlled studies, however, have yielded inconsistent results. Notably, studies so far did not control for odor pleasantness, although pleasantness is a critical determinant of emotional responses to odors. This study investigates mood lifting effects of d-(+)-limonene, the most prominent substance in citrus essential oils, with respect to odor quality judgments. Negative mood was induced within 78 participants using a helplessness paradigm (unsolvable social discrimination task). During this task, participants were continuously (mean duration: 19.5 min) exposed to d-(+)-limonene (n = 25), vanillin (n = 26), or diethyl phthalate (n = 27). Participants described their mood (Self-Assessment-Manikin, basic emotion ratings) and judged the odors’ quality (intensity, pleasantness, unpleasantness, familiarity) prior to and following the helplessness induction. The participants were in a less positive mood after the helplessness induction (p < 0.001), irrespective of the odor condition. Still, the more pleasant the participants judged the odors, the less effective the helplessness induction was in reducing happiness (p = 0.019). The results show no odor specific mood lifting effect of d-(+)-limonene, but indicate a positive effect of odor pleasantness on mood. The study highlights the necessity to evaluate odor judgments in aromatherapy research. PMID:26869973
The barriers to patient-driven treatment in mental health: why patients may choose to follow their own path.

Greenall, Paul

2006-01-01

The paper aims to explore the barriers that currently exist to patient-driven treatment within the field of mental health care and reform. This study represents action learning research using grounded theory to explore a possible causal basis for recidivism related to non-compliance with medication. Interviews addressed concerns from the literature around perceived barriers to patient-driven treatment evidenced by non-compliance with medically recommended pharmaceutical treatment. Results were correlated to look for emergent themes that were used to form the basis for subsequent interview questions. An analysis of the resulting emergent themes illustrated the importance of participatory treatment and coaching rather than medically applied paternalistic care, which is seen as encouraging learned helplessness on the part of patients. Similar helplessness was also revealed in clinicians themselves. Patients' awareness of their own needs and demands for more services place clients and the caregivers at odds over appropriate care in an environment of limited resources. The research was limited to only a small number of interviewees in one institution, all of whom were closely associated with mental illness in various capacities. The grounded theory nature of the research does, however, provide a framework for more research in other institutions to test and further explore some of the findings. The study demonstrated a reinforcement of Maslow's theory of needs hierarchy. The study illustrated a step-wise approach to treatment to decrease the rate of failure and recidivism in mental health care. The provision of a stable living environment was viewed as instrumental in improving patients' compliance with pharmaceutical treatment. An action plan was therefore created to initiate the support of a transitional/emergency house by various community groups in partnership with pharmaceutical manufacturing companies. Recidivism in mental health-created by non-compliance in pharmaceutical treatment, is a major issue in Canada's health care system. This study brings to the forefront issues from a number of perspectives in order to form a course of action in response to its findings.

Dopamine (DA) neurotransmission, particularly the ventral tegmental area-nucleus accumbens (VTA-NAcc) projection, underlies reward and aversion processing, and deficient DA function could underlie motivational impairments in psychiatric disorders. 6-hydroxydopamine (6-OHDA) injection is an established method for chronic DA depletion, principally applied in rat to study NAcc DA regulation of reward motivation. Given the increasing focus on studying environmental and genetic regulation of DA function in mouse models, it is important to establish the effects of 6-OHDA DA depletion in mice, in terms of reward and aversion processing. This mouse study investigated effects of 6-OHDA-induced NAcc DA depletion using the operant behavioural test battery of progressive ratio schedule (PRS), learned non-reward (LNR), learned helplessness (LH), treadmill, and in addition Pavlovian fear conditioning. 6-OHDA NAcc DA depletion, confirmed by ex vivo HPLC-ED, reduced operant responding: for gustatory reward under effortful conditions in the PRS test; to a stimulus recently associated with gustatory non-reward in the LNR test; to escape footshock recently experienced as uncontrollable in the LH test; and to avoid footshock by physical effort in the treadmill test. Evidence for specificity of effects to NAcc DA was provided by lack of effect of medial prefrontal cortex DA depletion in the LNR and LH tests. These findings add significantly to the evidence that NAcc DA is a major regulator of behavioural responding, particularly at the motivational level, to both reward and aversion. They demonstrate the suitability of mouse models for translational study of causation and reversal of pathophysiological DA function underlying motivation psychopathologies.

Establishing a learned-helplessness effect paradigm in C57BL/6 mice: behavioural evidence for emotional, motivational and cognitive effects of aversive uncontrollability per se.

2012-01-01

Uncontrollability of major life events has been proposed to be central to depression onset and maintenance. The learned helplessness (LH) effect describes a deficit in terminating controllable aversive stimuli in individuals that experienced aversive stimuli as uncontrollable relative to individuals that experienced the same stimuli as controllable. The LH effect translates across species and therefore can provide an objective-valid readout in animal models of depression. Paradigms for a robust LH effect are established and currently applied in rat but there are few reports of prior and current study of the LH effect in mouse. This includes the C57BL/6 mouse, typically the strain of choice for application of molecular-genetic tools in pre-clinical depression research. The aims of this study were to develop a robust paradigm for the LH effect in BL/6 mice, provide evidence for underlying psychological processes, and study the effect of a depression-relevant genotype on the LH effect. The apparatus used for in/escapable electro-shock exposure and escape test was a two-way shuttle arena with continuous automated measurement of locomotion, compartment transfers, e-shock escapes, vertical activity and freezing. Brother-pairs of BL/6 mice were allocated to either escapable e-shocks (ES) or inescapable e-shocks (IS), with escape latencies of the ES brother used as e-shock durations for the IS brother. The standard two-way shuttle paradigm was modified: the central gate was replaced by a raised divider and e-shock escape required transfer to the distal part of the safe compartment. These refinements yielded reduced superstitious, pre-adaptive e-shock transfers in IS mice and thereby increased the LH effect. To obtain a robust LH effect in all brother pairs, pre-screening for minor between-brother ES differences was necessary and did not confound the LH effect. IS mice developed reduced motor responses to e-shock, consistent with a motivational deficit, and absence of a learning curve for escapes at escape test, consistent with a cognitive deficit. When a tone CS was used to predict e-shock, IS mice exhibited increased reactivity to the CS, consistent with hyper-emotionality. There was no ES-IS difference in pain sensitivity. Mice heterozygous knockout for the 5-HTT gene exhibited an increased LH effect relative to wildtype mice. This mouse model will allow for the detailed molecular study of the aetiology, psychology, neurobiology and neuropharmacology of uncontrollability of aversive stimuli, a potential major aetiological factor and state marker in depression.

Behavioural studies on BR-16A (Mentat), a herbal psychotropic formulation.

PubMed

Bhattacharya, S K

1994-01-01

The anxiolytic, antidepressant and anti-aggression activities of Mentat were investigated in rats and mice, using standard behavioural paradigms. Single acute administration of Mentat, up to a dose of 200 mg/kg, ip, induced insignificant behavioural effects on the test parameters. However, when Mentat was administered subchronically for 7 days at two dose levels (50 and 100 mg/kg, intragastrically), the drug induced dose-related behavioural effects. Thus, it exhibited anxiolytic effect, as assessed by paradigms like the open-field test and elevated plus-maze tests in mice, and the social interaction test and Vogel's drink conflict test in rats. Furthermore, Mentat attenuated the increase in rat brain tribulin, a putative endocoid marker of anxiety, levels induced by pentylenetetrazole (20 mg/kg, sc), a known anxiogenic agent. Mentat attenuated footshock-induced aggressive behaviour in paired rats but failed to affect clonidine-induced automutilative behaviour. The observed aggression-attenuating effect of Mentat may be related to its anxiolytic activity. Mentat exhibited significant antidepressant effect as indicated by its ability to reduce swim stress induced immobility in Porsolt's behavioural despair test, reduction in escape failures concomitant with an increase in avoidance response in the learned helplessness test, and attenuation of muricidal behaviour, in rats. The observed behavioural effects are consonant with the reported clinical utility of Mentat as an adjuvant in the treatment of anxiety and depression.

Women with advanced ovarian cancer generally have a poor prognosis but there is significant variability in survival despite similar disease characteristics and treatment regimens. The aim of this study was to determine whether psychosocial factors predict survival in women with ovarian cancer, controlling for potential confounders. The sample comprised 798 women with invasive ovarian cancer recruited into the Australian Ovarian Cancer Study and a subsequent quality of life study. Validated measures of depression, optimism, minimization, helplessness/hopelessness, and social support were completed 3-6 monthly for up to 2 years. Four hundred nineteen women (52.5 %) died over the follow-up period. Associations between time-varying psychosocial variables and survival were tested using adjusted Cox proportional hazard models. There was a significant interaction of psychosocial variables measured prior to first progression and overall survival, with higher optimism (adjusted hazard ratio per 1 standard deviation (HR) = 0.80, 95 % confidence interval (CI) 0.65-0.97), higher minimization (HR = 0.79, CI 0.66-0.94), and lower helplessness/hopelessness (HR = 1.40, CI 1.15-1.71) associated with longer survival. After disease progression, these variables were not associated with survival (optimism HR = 1.10, CI 0.95-1.27; minimization HR = 1.12, CI 0.95-1.31; and helplessness/hopelessness HR = 0.86, CI 0.74-1.00). Depression and social support were not associated with survival. In women with invasive ovarian cancer, psychosocial variables prior to disease progression appear to impact on overall survival, suggesting a preventive rather than modifying role. Addressing psychosocial responses to cancer and their potential impact on treatment decision-making early in the disease trajectory may benefit survival and quality of life.
Overlapping neurobiology of learned helplessness and conditioned defeat: Implications for PTSD and mood disorders

Hammack, Sayamwong E.; Cooper, Matthew A.; Lezak, Kimberly R.

2012-01-01

Exposure to traumatic events can increase the risk for major depressive disorder (MDD) as well as posttraumatic stress disorder (PTSD), and pharmacological treatments for these disorders often involve the modulation of serotonergic (5-HT) systems. Several behavioral paradigms in rodents produce changes in behavior that resemble symptoms of MDD and these behavioral changes are sensitive to antidepressant treatments. Here we review two animal models in which MDD-like behavioral changes are elicited by exposure to an acute traumatic event during adulthood, learned helplessness (LH) and conditioned defeat. In LH, exposure of rats to inescapable, but not escapable, tailshock produces a constellation of behavioral changes that include deficits in fight/flight responding and enhanced anxiety-like behavior. In conditioned defeat, exposure of Syrian hamsters to a social defeat by a more aggressive animal leads to a loss of territorial aggression and an increase in submissive and defensive behaviors in subsequent encounters with non-aggressive conspecifics. Investigations into the neural substrates that control LH and conditioned defeat revealed that increased 5-HT activity in the dorsal raphe nucleus (DRN) is critical for both models. Other key brain regions that regulate the acquisition and/or expression of behavior in these two paradigms include the basolateral amygdala (BLA), central nucleus of the amygdala (CeA) and bed nucleus of the stria terminalis (BNST). In this review, we compare and contrast the role of each of these neural structures in mediating LH and conditioned defeat, and discuss the relevance of these data in developing a better understanding of the mechanisms underlying trauma-related depression.

Episodic experiences of stress have been identified as the leading cause of major depressive disorder (MDD). The occurrence of MDD is profoundly influenced by the individual's coping strategy, rather than the severity of the stress itself. Resting brain activity has been shown to alter in several mental disorders. However, the functional relationship between resting brain activity and coping strategies has not yet been studied. In the present study, we observed different patterns of resting brain activity in rats that had determined either positive (resilient to stress) or negative (vulnerable to stress) coping strategies, and examined whether modulation of the preset resting brain activity could influence the behavioral phenotype associated with negative coping strategy (i.e., depressive-like behaviors). We used a learned helplessness paradigm-a well-established model of MDD-to detect coping strategies. Differences in resting state brain activity between animals with positive and negative coping strategies were assessed using 18 F-fluorodeoxyglucose positron emission tomography (FDG-PET). Glutamatergic stimulation was used to modulate resting brain activity. After exposure to repeated uncontrollable stress, seven of 23 rats exhibited positive coping strategies, while eight of 23 rats exhibited negative coping strategies. Increased resting brain activity was observed only in the left ventral dentate gyrus of the positive coping rats using FDG-PET. Furthermore, glutamatergic stimulation of the left dentate gyrus abolished depressive-like behaviors in rats with negative coping strategies. Increased resting brain activity in the left ventral dentate gyrus helps animals to select positive coping strategies in response to future stress. Copyright © 2016 Elsevier Inc. All rights reserved.

This study evaluates the ability of the hopelessness theory of depression's etiological chain to account for this relation in a sample of 297 undergraduates. Results indicated that emotional, but not physical or sexual, maltreatment was uniquely related to average levels of suicidal ideation across a 2.5-year follow-up. (Author)

Two studies had children role-play successful and unsuccessful tasks to test the hypothesis that both criticism and praise that conveyed person or trait judgments could send a message of contingent worth and undermine subsequent coping. Found that 5- to 6-year olds displayed significantly more "helpless" responses after person criticism or praise…
Transforming helplessness: an approach to the therapy of "stuck" couples.

Fineberg, D E; Walter, S

1989-09-01

Therapists working with couples often find themselves frustrated when they proceed to negotiate conflicts, even when the historical antecedents and psychological dynamics seem well understood. Despite the genuine willingness of each member to negotiate a solution, they remain stuck in demands that the other take the first steps toward change. This article proposes that a crucial step--transforming helplessness--must precede efforts at fostering communication/negotiation skills. A four-square analysis of the situation helps to explain how this stalemate occurs. Also, it points the way to strategies that can transform the couple's attitudes from helpless complaining to empowered, creative action. Three case examples illustrate clinical applications of this approach.

The good news is that we can be effective teachers, clinicians, interactors, and consultants, enabling the learner, ourselves, and significant others to communicate more effectively with one another. The bad news is that we can be ineffectual, often leading the learner to learned helplessness, prompt dependency, and possibly self-injurious behaviors. Extreme measures may be the only means that we have given the learner to communicate intents such as, "Stop intruding on my space," or "Come attend to me." We can set ourselves and the learner up for success or for failure. We, as service providers, have choices and options as well.
Helplessness predicts the development of hypertension in older Mexican and European Americans.

Stern, Stephen L; Dhanda, Rahul; Hazuda, Helen P

2009-10-01

The mechanisms by which depression is associated with an elevated risk of cardiovascular disease remain unclear. It is possible that depressive symptoms could increase the risk of hypertension, which in turn could predispose to cardiovascular disease. The goal of this study was to explore whether individual depressive symptoms might predict the incidence of hypertension in a cohort of 240 initially normotensive Mexican-American and European-American elders. Subjects were 65-78 years old on entering the San Antonio Longitudinal Study of Aging, an epidemiologic survey, at which time they completed the 30-item Geriatric Depression Scale in English or Spanish. Their blood pressure was reassessed a mean of 7.0 years later. Responses to six key scale items (depressed mood, decreased interest, worthlessness, hopelessness, helplessness, and fatigue) were evaluated for the ability to predict incident hypertension. In univariate analyses, only helplessness significantly predicted incident hypertension (chi-square 13.5, df=1, P=.0003). In a Cox proportional hazards model adjusted for sex, education, number of comorbid diseases, current drinking, social well-being, and marital status, helplessness remained a very strong predictor [hazard ratio (HR) 4.99, 95% confidence interval (CI) 1.90-13.12, P=.0011]. Total depression score also predicted incident hypertension, but less strongly (HR 1.08, CI 1.00-1.17, P=.0339). Helplessness may predict the development of hypertension in the elderly. Further research into this relationship might lead to interventions to reduce the risk of cardiovascular disease.
Sleep and memory. I: The influence of different sleep stages on memory.

PubMed

Rotenberg, V S

1992-01-01

A new approach to the sleep stages role in memory is discussed in the context of the two opposite patterns of behavior-search activity and renunciation of search. Search activity is activity designed to change the situation (or the subjects attitudes to it) in the absence of a definite forecast of the results of such activity, but with the constant consideration of these results at all stages of activity. Search activity increases general adaptability and body resistance while renunciation of search decreases adaptability and requires REM sleep for its compensation. Unprepared learning, which is often accompanied by failures on the first steps of learning, is suggested to produce renunciation of search, which decreases learning ability, suppress retention, and increase REM sleep requirement. A prolonged REM sleep deprivation before training causes learned helplessness and disturbs the learning process, while short REM sleep deprivation cause the "rebound" of the compensatory search activity that interferes with passive avoidance. REM sleep deprivation performed after a training session can increase distress caused by a training procedure, with the subsequent negative outcome on retention.

The objective of this study is to examine the gender (sex) differentiation of indirect self-destructiveness and its manifestations as well as its relationships with suicide attempt methods in females and males. The study was conducted among 147 persons (114 females, 33 males) who attempted suicide. The research instrument was the polish version of the Chronic Self-Destructiveness Scale including Transgression and Risk, Poor Health Maintenance, Personal and Social Neglects, Lack of Planfulness, and Helplessness and Passiveness in the face of problems. Differences testing and correlation analyses were applied. Females scored higher on poor health maintenance and males scored significantly higher on personal and social neglects, lack of planfulness, and helplessness. Noteworthy is that the intensity of indirect self-destructiveness in females reached the same magnitude as in males. A number of statistically significant correlations were found between indirect self-destructiveness, or its manifestations, and the methods of suicide attempt in the two groups. Among these categories, the highest contribution was of helplessness and passiveness (both of groups), poor health maintenance (males), and personal and social neglects (females). Results of this study can be useful in the therapeutic efforts and prevention of not only indirectly self-destructive behaviours but also possible suicide attempts. Both preventive and therapeutic activities can take into account the specificity of those phenomena resulting from one's sex/gender. It is important to adapt preventive and therapeutic measures to psychological (personal) features that arise from an individual's sex/gender.

Natural disasters are too often presented as resulting from extreme natural phenomena affecting helpless populations, with people being insufficiently aware of the factors leading to disasters and of the existing strategies to mitigate their impacts. We developed a board game aimed at raising awareness about geohazards and disaster risk reduction strategies. The target groups are (1) secondary school students and citizens and (2) scientists and stakeholders involved in risk management activities. For the first group, the aim is to induce a better understanding of the geohazards and disasters they are confronted with in the media or in their daily lives; for the second, the objective is to generate discussion about risk management strategies. The game was tested with students in Belgium and with citizens, earth scientists, and risk managers in several African countries. Based on analysis of the most common game strategies observed, the players' reactions during the game, and their answers to a short questionnaire, we analyzed the main learning outcomes conveyed by this game. The game Hazagora appears to positively enhance the players' insights into processes involved in disasters. As such, the game is an effective, fun learning tool to introduce participants to the concepts of geohazards and disasters and to generate discussion.

Mediators and Moderators of the Association Between Stalking Victimization and Psychological Distress.

2017-03-01

The current study aims to understand mediators and moderators of the relationship between stalking victimization and depression. Based on the reformulated learned helplessness theory, which emphasizes the role of internal, global, and stable attributions for negative events in the development of depression, we predicted that the association between stalking victimization and depression would be mediated by attributions for the stalking and characterological self-blame. We predicted that the association between stalking victimization and helplessness attributions or characterological self-blame, in turn, would be moderated by gender, sex-role identity, and length of stalking. Specifically, we hypothesized that female victims, victims possessing a feminine sex-role identity, and victims experiencing longer stalking episodes would be more likely to experience depression in comparison with male victims, victims possessing a masculine sex-role identity, and victims experiencing shorter stalking episodes. The results indicated that global attributions for the cause of stalking significantly mediated the relationship between stalking victimization and depression. The results for stable attributions, internal attributions, and characterological self-blame were nonsignificant. Furthermore, gender, sex-role identity, and length of stalking did not moderate the association between stalking and attributional style or characterological self-blame. The implications of these findings and directions for future research are discussed.
Linguistic Evidence for the Failure Mindset as a Predictor of Life Span Longevity.

When people think that their efforts will fail to achieve positive outcomes, they sometimes give up their efforts after control, which can have negative health consequences. Problematic orientations of this type, such as pessimism, helplessness, or fatalism, seem likely to be associated with a cognitive mindset marked by higher levels of accessibility for failure words or concepts. Thus, the purpose of the present research was to determine whether there are individual differences in the frequency with which people think about failure, which in turn are likely to impact health across large spans of time. Following self-regulatory theories of health and the learned helplessness tradition, two archival studies (total n = 197) scored texts (books or speeches) for their use of failure words, a category within the Harvard IV dictionary of the General Inquirer. People who used failure words more frequently exhibited shorter subsequent life spans, and this relationship remained significant when controlling for birth year. Furthermore, study 2 implicated behavioral factors. For example, the failure/longevity relationship was numerically stronger among people whose causes of death appeared to be preventable rather than non-preventable. These results significantly extend our knowledge of the personality/longevity relationship while highlighting the value of individual differences in word usage as predictors of health and mortality.

Advancing knowledge on practice change: linking facilitation to the senses framework.

PubMed

Cooper, Julie; Meyer, Julienne; Holman, Cheryl

2013-06-01

To explore the facilitating factors that enabled staff on a rehabilitation ward for older people engage in change activities. The importance of facilitation in practice change is widely acknowledged; however, little nursing research has taken place in relation to its nature. Following identification in the early phases of an action research study that learned helplessness states and the use of socially structured defence techniques were preventing staff on a rehabilitation ward for older people from engaging in practice development, some change was achieved. What facilitated this to take place needed to be explored. An action research approach was used. Data gained from 13 in-depth interviews with staff and managers together with three years of researcher field notes were analysed using thematic analysis. The continuous presence and neutrality of the researcher who worked together with staff on their issues of concern using a flexible ward-based approach, combined with giving staff the opportunity to explore what it was like for them working in this area, were considered key in helping staff to engage with change. Analysis of findings suggests that the senses framework presents a theoretical approach to facilitation that can help staff move out of learned helplessness states and reduce the need for the use of socially structured defence techniques. This study identifies a facilitation approach that enabled staff to engage with practice change. Although carried out in the UK, its findings have wider relevance through the application of a theoretical perspective for practice change facilitation that has not before been considered in this literature, and which is likely to be of interest to those involved in practice change internationally. © 2013 Blackwell Publishing Ltd.

Independent investigations have shown that socioeconomic status (SES) and learned helplessness (LH) are associated with poor disease outcome in patients with rheumatoid arthritis (RA). Our aim was to investigate the cross-sectional relationship between SES, LH, and disease outcome in patients with recent-onset inflammatory polyarthritis (IP), the broader group of conditions of which RA is the major constituent. SES was measured using the Index of Multiple Deprivation 2007 for 553 patients consecutively recruited to the Norfolk Arthritis Register. Patients also completed the Rheumatology Attitudes Index, a measure of LH. SES and LH were investigated as predictors of disease outcome (functional disability [Health Assessment Questionnaire (HAQ)] and disease activity [Disease Activity Score in 28 joints]) in a regression analysis, adjusted for age, sex, and symptom duration. The role of LH in the relationship between SES and disease outcome was then investigated. Compared to patients of the highest SES, those of the lowest SES had a significantly worse outcome (median difference in HAQ score 0.42; 95% confidence interval [95% CI] 0.08, 0.75). Compared to patients with normal LH, patients with low LH had a significantly better outcome and patients with high LH had a significantly worse outcome (median difference in HAQ score 1.12; 95% CI 0.82, 1.41). There was a significant likelihood that LH mediated the association between SES and disease outcome (P = 0.04). LH is robustly associated with cross-sectional disease outcome in patients with IP, and appears to mediate the relationship between SES and disease outcome. As LH is potentially modifiable, these findings have potential clinical implications. Copyright © 2012 by the American College of Rheumatology.
Overlapping neurobiology of learned helplessness and conditioned defeat: implications for PTSD and mood disorders.

Hammack, Sayamwong E; Cooper, Matthew A; Lezak, Kimberly R

2012-02-01

Exposure to traumatic events can increase the risk for major depressive disorder (MDD) as well as posttraumatic stress disorder (PTSD), and pharmacological treatments for these disorders often involve the modulation of serotonergic (5-HT) systems. Several behavioral paradigms in rodents produce changes in behavior that resemble symptoms of MDD and these behavioral changes are sensitive to antidepressant treatments. Here we review two animal models in which MDD-like behavioral changes are elicited by exposure to an acute traumatic event during adulthood, learned helplessness (LH) and conditioned defeat. In LH, exposure of rats to inescapable, but not escapable, tailshock produces a constellation of behavioral changes that include deficits in fight/flight responding and enhanced anxiety-like behavior. In conditioned defeat, exposure of Syrian hamsters to a social defeat by a more aggressive animal leads to a loss of territorial aggression and an increase in submissive and defensive behaviors in subsequent encounters with non-aggressive conspecifics. Investigations into the neural substrates that control LH and conditioned defeat revealed that increased 5-HT activity in the dorsal raphe nucleus (DRN) is critical for both models. Other key brain regions that regulate the acquisition and/or expression of behavior in these two paradigms include the basolateral amygdala (BLA), central nucleus of the amygdala (CeA) and bed nucleus of the stria terminalis (BNST). In this review, we compare and contrast the role of each of these neural structures in mediating LH and conditioned defeat, and discuss the relevance of these data in developing a better understanding of the mechanisms underlying trauma-related depression.

Effects of hypoxic preconditioning on expression of transcription factor NGFI-A in the rat brain after unavoidable stress in the "learned helplessness" model.

2010-07-01

We report here our immunocytochemical studies establishing that the development of a depression-like state in rats following unavoidable stress in a "learned helplessness" model is accompanied by stable activation of the expression of transcription factor NGFI-A in the dorsal hippocampus (field CA1) and the magnocellular paraventricular nucleus of the hypothalamus, along with an early wave of post-stress expression, which died down rapidly, in the ventral hippocampus (the dentate gyrus) and a long period of up to five days of high-level expression in the neocortex. In rats subjected to three sessions of preconditioning consisting of moderate hypobaric hypoxia (360 mmHg, 2 h, with intervals of 24 h), which did not form depression in these circumstances, there were significant changes in the dynamics of immunoreactive protein content in the hippocampus, with a stable increase in expression in the ventral hippocampus and only transient and delayed (by five days) expression in field CA1. In the neocortex (layer II), preconditioning eliminated the effects of stress, preventing prolongation of the first wave of NGFI-A expression to five days, while in the magnocellular hypothalamus, conversely, preconditioning stimulated a second (delayed) wave of the expression of this transcription factor. The pattern of NGFI-A expression in the hippocampus, neocortex, and hypothalamus seen in non-preconditioned rats appears to reflect the pathological reaction to aversive stress, which, rather than adaptation, produced depressive disorders. Post-stress modification of the expression of the product of the early gene NGFI-A in the brain induced by hypoxic preconditioning probably plays an important role in increased tolerance to severe psychoemotional stresses and is an important component of antidepressant mechanisms.

The present study evaluates a group intervention using a feminist approach for women experiencing sexual abuse in childhood or adulthood in order to measure changes associated with participation in a group intervention and verifies whether effects are maintained over time. The present study relates effects of the group intervention in terms of psychological distress, depression symptoms, post-traumatic stress symptoms and feelings of guilt and helplessness. The sample consists of 26 women participating in a group intervention offered by sexual assault centers in Quebec (CALACS - Centre d'aide et de lutte contre les agressions à caractère sexuel). Results show significant differences between pretest and post-test scores obtained one week following the end of the group intervention and gains are maintained at follow-up 3 months later. The findings suggest that participation in the group intervention is associated with a reduction of psychological distress, depression symptoms, post-traumatic stress symptoms and feelings of guilt and helplessness in adult women reporting sexual abuse.

Stereotype threat affects performance in many different groups across many different domains. Despite a large body of experimental research on situational stereotype threat, little attention has been paid to the consequences of repeated experience of stereotype threat. Using structural equation modeling on data from a representative sample of girls from secondary schools, the current research examined the relations of chronic stereotype threat with mathematical achievement, and effectiveness of working memory functions. Moving beyond past theory, this study examined a new mechanism by which chronic stereotype threat decreases school achievement – namely intellectual helplessness. We assumed that repeated experience of stereotype threat works as intellectual helplessness training. After the phase of cognitive mobilization, cognitive exhaustion appears, because the individual has no gain from intense cognitive effort. Corroborating previous research on acute stereotype threat, we demonstrated that chronic stereotype threat is negatively associated with mathematical achievement. Additionally, it was also associated with lower effectiveness of working memory functions, which seems to show depletion of working memory as an effect of chronic stereotype threat. The results also demonstrated that both mediational paths from chronic stereotype threat to mathematical achievement: through working memory depletion and through intellectual helplessness were significant but only for girls that were highly identified with their gender group. In sum, we extended a well-established model of acute stereotype threat to its chronic version and suggested a new mechanism of chronic stereotype threat, which involves intellectual helplessness. Implications for stereotype threat theory and educational practice are discussed. PMID:29666599

Chronic pain and depression are highly comorbid; however, the longitudinal link is only partially understood. This study examined direct and indirect effects of chronic back pain on depression using path analysis in a general population sample, focussing on cognitive mediator variables. Analyses are based on 413 participants (aged 18-75 years) in a population-based postal survey on back pain who reported chronic back pain at baseline. Follow-up data were collected after 1 year. Depression was measured with the Center for Epidemiologic Studies Depression Scale (CES-D). Fear-avoidance-beliefs (FABQ), catastrophizing and helplessness/hopelessness (KRSS) were considered as cognitive mediators. Data were analyzed using path analysis. Chronic back pain had no direct effect on depression at follow-up when controlling for cognitive mediators. A mediating effect emerged for helplessness/hopelessness but not for catastrophizing or fear-avoidance beliefs. These results support the cognitive mediation hypothesis which assumes that psychological variables mediate the association between pain and depression. The importance of helplessness/hopelessness is of relevance for the treatment of patients with chronic back pain.

Stress has been associated with high-calorie, low-nutrient food intake (HCLN) and emotion-driven eating (EDE). However, effects on healthy food intake remain unknown. This study examined two facets of stress (self-efficacy, perceived helplessness) and food consumption, mediated by EDE. Cross-sectional data from fourth-graders (n=978; 52% female, 28% Hispanic) in an obesity intervention used self-report to assess self-efficacy, helplessness, EDE, fruit/vegetable (FV) intake, and high-calorie/low-nutrient (HCLN) food. Higher stress self-efficacy was associated with higher FV intake, β=.354, p<0.001, and stress perceived helplessness had an indirect effect on HCLN intake through emotion-driven eating, indirect effect=.094, p<0.001; χ(2)(347)=659.930, p<0.001, CFI=0.940, TLI=0.930, RMSEA=0.030, p=1.00, adjusting for gender, ethnicity, BMI z-score, and program group. Stress self-efficacy may be more important for healthy food intake and perceived helplessness may indicate emotion-driven eating and unhealthy snack food intake. Obesity prevention programs may consider teaching stress management techniques to avoid emotion-driven eating. Copyright © 2015 Elsevier Ltd. All rights reserved.
Potential suicide ideation and its association with observing bullying at school.

To explore those contextual factors that predict potential suicide ideation among students who observe bullying at school. 1,592 students of whom 1,009 who reported having observed bullying at school were surveyed from 14 secondary schools in the North of England. Role-related (not-involved, victim, perpetrator, 'bully-victim' and observer) and gender-wise comparisons of key variables were undertaken prior to hierarchical multiple regressions to determine those associated with potential suicide ideation. Analyses indicated that students who observed bullying behavior were significantly more likely than those not involved in bullying to report symptoms of interpersonal sensitivity, to indicate greater helplessness and potential suicide ideation. Hierarchical multiple regression analyses indicated that, among boys, helplessness (β = .48, p < .001) followed by frequency of bullying perpetration (β = .11, p < .001), and a less supportive home climate (β = -.10, p < .004) were associated with potential suicide ideation. Helplessness was found to be the only variable associated with potential suicide ideation among girls (β = .49, p < .001). Perceived helplessness is significantly associated with potential suicide ideation among students who observe bullying at school. Copyright © 2013 Society for Adolescent Health and Medicine.

Results Higher stress self-efficacy was associated with higher FV intake, β = .354, p < 0.001, and stress perceived helplessness had an indirect effect on HCLN intake through emotion-driven eating, indirect effect = .094, p < 0.001; χ2(347) = 659.930, p < 0.001, CFI = 0.940, TLI = 0.930, RMSEA = 0.030, p = 1.00, adjusting for gender, ethnicity, BMI z-score, and program group. Conclusions and Implications Stress self-efficacy may be more important for healthy food intake and perceived helplessness may indicate emotion-driven eating and unhealthy snack food intake. Obesity prevention programs may consider teaching stress management techniques to avoid emotion-driven eating. PMID:26004248
Effects of signaling inescapable shock on subsequent escape learning: implications for theories of coping and "learned helplessness".

PubMed

Jackson, R L; Minor, T R

The present experiments reveal that shuttle-escape performance deficits are eliminated when exteroceptive cues are paired with inescapable shock. Experiment 1 indicated that, as in instrumental control, a signal following inescapable shock eliminated later escape performance deficits. Subsequent experiments revealed that both forward and backward pairings between signals and inescapable shock attenuated performance deficits. However, the data also suggest that the impact of these temporal relations may be modulated by qualitative aspects of the cues because the effects of these relations depended upon whether an increase or decrease in illumination (Experiment 2) or a compound auditory cue (Experiment 4) was used. Preliminary evidence suggests that the ability of illumination cues to block escape learning deficits may be related to their to reduce contextual fear (Experiment 3). The implications of these data for conceptions of instrumental control and the role of fear in the etiology of effects of inescapable shock exposure are discussed.
Rodent models of depression: learned helplessness induced in mice.

Anisman, H; Merali, Z

Uncontrollable stressors induce a variety of behavioral disturbances that are in many ways reminiscent of the symptoms that characterize clinical depression. These deficits are evident across a range of species, including mice. Given the increasing focus on genetic techniques involving mice to identify the mechanisms subserving these behavioral disturbances (e.g., recombinant, knockout, and transgenic strains), it is of particular interest to provide a detailed description of the method to induce behavioral deficits in response to uncontrollable stressors. This unit describes the procedure used to assess the effects of controllable and uncontrollable shock on subsequent shock escape performance in mice using an escape-delay procedure.

Background The experience of uncontrollability and helplessness in the face of stressful life events is regarded as an important determinant in the development and maintenance of depression. The inability to successfully deal with stressors might be linked to dysfunctional prefrontal functioning. We assessed cognitive, behavioural and physiological effects of stressor uncontrollability in depressed and healthy individuals. In addition, relationships between altered cortical processing and cognitive vulnerability traits of depression were analysed. Method A total of 26 unmedicated depressed patients and 24 matched healthy controls were tested in an expanded forewarned reaction (S1–S2) paradigm. In a factorial design, stressor controllability varied across three consecutive conditions: (a) control, (b) loss of control and (c) restitution of control. Throughout the experiment, error rates, ratings of controllability, arousal, emotional valence and helplessness were assessed together with the post-imperative negative variation (PINV) of the electroencephalogram. Results Depressed participants showed an enhanced frontal PINV as an electrophysiological index of altered information processing during both loss of control and restitution of control. They also felt more helpless than controls. Furthermore, frontal PINV magnitudes were associated with habitual rumination in the depressed subsample. Conclusions These findings indicate that depressed patients are more susceptible to stressor uncontrollability than healthy subjects. Moreover, the experience of uncontrollability seems to bias subsequent information processing in a situation where control is objectively re-established. Alterations in prefrontal functioning appear to contribute to this vulnerability and are also linked to trait markers of depression. PMID:18466665
Beyond the basics. Effects of the Eden Alternative model on quality of life issues.

PubMed

Bergman-Evans, Brenda

2004-06-01

In Life Worth Living, Thomas (1996) proposed that in long-term care facilities for elderly individuals, loneliness, helplessness, and boredom are out of control and are steadily decaying the residents' spirits, adversely affecting quality of life. While Thomas' contention appeals to common sense, no empirical evidence is offered in its support. The purpose of this quasi-experimental study was to assess the impact of implementation of the Eden Alternative model on levels of loneliness, boredom, and helplessness of older residents of a long-term care facility. The model was introduced into the experimental facility on May 1, 1998. The final sample for the experimental group included 21 cognitively intact older adults from a state veterans home (13 men, 8 women, mean age = 76.1). The final control group was composed of 13 residents in a private long-term care facility (11 women, 2 men, mean age = 85.7). A Background Data Sheet, the Geriatric Depression Scale (includes yes or no questions related to helplessness and boredom), and the UCLA Loneliness Scale (Version 3) were administered by an interviewer at baseline and 1-year post-implementation of the Eden Alternative model. Data analysis from the post-implementation phase revealed significant differences between the groups on levels of boredom (z = -2.6, p = .01) and helplessness (z = -2.2, p = .03). Lower levels of distress were found in the experimental group on both boredom and helplessness, but not loneliness. Findings suggest health care professionals and researchers have an opportunity to take a leading role in impacting services related to quality-of-life issues for this important, but often overlooked, population.

The aim of this study was to estimate the concurrent validity of the Hopelessness, Helplessness, and Haplessness Scale developed by Lester (1998). Data were obtained from 75 psychiatric patients. Cronbach alphas ranged from .67 to .90. Scores on the scales were associated with Beck, Weissman, Lester, and Trexler's measure of hopelessness, with the correlation strongest for the new hopelessness scale.
Protection against perceptions of powerlessness and helplessness during palliative care: the family members' perspective.

Milberg, Anna; Strang, Peter

2011-09-01

Resilience in relation to coping with stress, loss, and bereavement has recently received increased attention. The aim of the current study was to describe aspects that are experienced as a protection against powerlessness and/or helplessness during advanced palliative home care (APHC) or as a help when coping with such perceptions. Both family members during ongoing APHC and family members 3-9 months after the patient's death responded (in total, N = 233; response rate 72%) to a postal questionnaire with mainly open-ended questions. The text responses were analyzed using Manifest Content Analysis. Protection against powerlessness and helplessness had been facilitated by a stable patient condition, the patient coping well, a trusting relationship with the patient, practical and emotional support from family and friends, access to palliative expertise, and staff support that was both individually-focused and cooperative. Other aspects that had helped or protected family members against powerlessness and helplessness were a belief that they had their own reliable knowledge to manage the difficult situation, talking to someone, doing good for the patient, distracting activities, acceptance, meaning and hope, and an inner feeling of security. The findings are discussed in relation to existential psychology, the dual process model of coping with bereavement, and repressive coping. Clinical implications are suggested.

To examine the role of parenting style in achieving metabolic control and treatment adherence in adolescents with type 1 diabetes. Parents of 100 adolescents with type 1 diabetes completed assessments of their parenting style and sense of helplessness. Parents and patients rated patient adherence to the treatment regimen. Glycemic control was evaluated by HbA(1c) values. An authoritative paternal parenting style predicted better glycemic control and adherence in the child; a permissive maternal parenting style predicted poor adherence. A higher sense of helplessness in both parents predicted worse glycemic control and lesser adherence to treatment. Parental sense of helplessness was a significant predictor of diabetes control after correcting for other confounders (patient age, sex, and treatment method). An authoritative nonhelpless parenting style is associated with better diabetes control in adolescents. Paternal involvement is important in adolescent diabetes management. These results have implications for psychological interventions.

The Environmental Noise Directive expects residents to be actively involved in localising and selecting noise abatement interventions during the noise action planning process. Its intervention impact is meant to be homogeneous across population groups. Against the background of social heterogeneity and environmental disparities, however, the impact of noise action planning on exposure to traffic-related noise and its health effects is unlikely to follow homogenous distributions. Until now, there has been no study evaluating the impact of noise action measures on the social distribution of traffic-related noise exposure and health outcomes. We develop a conceptual (logic) model on cognitive-motivational determinants of residents’ civic engagement and health (inequities) by integrating arguments from the Model on household’s Vulnerability to the local Environment, the learned helplessness model in environmental psychology, the Cognitive Activation Theory of Stress, and the reserve capacity model. Specifically, we derive four hypothetical patterns of cognitive-motivational determinants yielding different levels of sustained physiological activation and expectancies of civic engagement. These patterns may help us understand why health inequities arise in the context of noise action planning and learn how to transform noise action planning into an instrument conducive to health equity. While building on existing frameworks, our conceptual model will be tested empirically in the next stage of our research process. PMID:28556813

Manifest dream content as a possible predictor of suicidality.

PubMed

Glucksman, Myron L

2014-12-01

The prediction of suicidal intent remains a clinical problem. This presentation illustrates that a distinction may be made between the manifest dream reports of patients who are potentially or acutely suicidal and those who are not. A review of the literature reveals that the manifest dream reports of clinically depressed, non-suicidal individuals differ from those who are depressed and acutely suicidal. The former contain themes of loss, disappointment, rejection, helplessness, hopelessness, failure, and death. The latter contain themes of dying, death, destruction, and violence directed toward the dreamer or others, as well as hopelessness and helplessness. The author collected manifest dream reports from three clinically depressed, non-suicidal patients and three clinically depressed, potentially or acutely suicidal patients. There are apparent differences between the themes of manifest dream reports in the clinically depressed, non-suicidal patients and the clinically depressed, potentially or acutely suicidal patients. The former contain themes of death, loss, rejection, vulnerability, hopelessness, and helplessness. The latter contain themes of active harm or violence (specifically toward the dreamer), dying or being dead, aloneness, vulnerability, hopelessness, and helplessness. Clinical cases and corresponding manifest dream reports are presented. Although this is a preliminary study, it is possible that manifest dream content may be used as one of the predictors of suicidality, in conjunction with latent dream content, diagnosis, life circumstance, and clinical status.

Despite a relatively high rate of suicide associated with cancer, this issue has not been explored in Korean patients. This study investigates the prevalence and factors related to 'the desire for hastened death' (DHD) in Korean cancer patients. A cross-sectional survey using standardised measures, including the Schedule of Attitudes toward Hastened Death and the Hospital Anxiety and Depression Scale, was performed with 131 patients with different types of cancer. 13.7% of the participants experienced moderate DHD (Schedule of Attitudes toward Hastened Death scores 5-9) and 1.7% experienced high DHD (≥10). Socio-demographic and disease-associated factors of the DHD included age, overall health and shortness of breath. The majority of psychosocial variables such as sadness, distress, 'helplessness/hopelessness' and 'anxious preoccupation' had a moderate association with DHD. Patients with a clinically significant level of anxiety or depression reported higher levels of DHD. Other significant correlates included 'meaning/peace', a sense of burdening family, dignity impairment and suicidal thoughts after diagnosis. Helplessness/hopelessness and anxiety were the strongest predictors of DHD in multivariate analysis. In view of significant role of helplessness/hopelessness and anxiety in the DHD of cancer patients, careful monitoring and management of these factors should be an integral part of cancer care to reduce the occurrence of DHD. © 2010 Blackwell Publishing Ltd.
Academic procrastination, emotional intelligence, academic self-efficacy, and GPA: a comparison between students with and without learning disabilities.

Hen, Meirav; Goroshit, Marina

Academic procrastination has been seen as an impediment to students' academic success. Research findings suggest that it is related to lower levels of self-regulated learning and academic self-efficacy and associated with higher levels of anxiety, stress, and illness. Emotional intelligence (EI) is the ability to assess, regulate, and utilize emotions and has been found to be associated with academic self-efficacy and a variety of better outcomes, including academic performance. Students with learning disabilities (LD) are well acquainted with academic difficulty and maladaptive academic behavior. In comparison to students without LD, they exhibit high levels of learned helplessness, including diminished persistence, lower academic expectations, and negative affect. This study examined the relationships among academic procrastination, EI, and academic performance as mediated by academic self-efficacy in 287 LD and non-LD students. Results indicated that the indirect effect of EI on academic procrastination and GPA was stronger in LD students than in non-LD students. In addition, results indicated that LD students scored lower than non-LD students on both EI and academic self-efficacy and higher on academic procrastination. No difference was found in GPA.

Purpose To examine the measurement properties of measures of psychological constructs in people with knee osteoarthritis. Method Participants with osteoarthritis of the knee completed the beck depression inventory (BDI-II), state-trait anxiety inventory (STAI), arthritis helplessness index (AHI), fatigue severity scale (FSS), coping strategies questionnaire (CSQ), beliefs about pain control questionnaire (BPCQ), illness perceptions questionnaire-revised (IPQ-R), pain self-efficacy questionnaire (PSEQ) at home as part of a set of measures covering different aspects of osteoarthritis pain. The questionnaires were returned by pre-paid envelope. Rasch analysis was used to check the psychometric properties of the scales in people with osteoarthritis. Results The STAI-SF was an acceptable measure of anxiety and the revised FSS an acceptable measure of fatigue, with removal of items 1 and 2. The BDI subscales were acceptable for measuring negative thoughts and behaviours related to depressive symptomatology with some modifications to the scale. The helplessness scale of the AHI was acceptable as a measure of helplessness. The PSEQ was an acceptable measure of self-efficacy and the CSQ as a measure of cognitive coping strategies. The BPCQ and IPQ-R did not fit the Rasch model. Conclusions These findings indicate that questionnaires need to be checked for their ability to measure psychological constructs in the clinical groups to which they will be applied. Implications for Rehabilitation For people with osteoarthritis, the STAI-SF is an acceptable measure of anxiety and the revised FSS an acceptable measure of fatigue with removal of items 1 and 2. The BDI subscales, but not the total score, are acceptable for measuring depressive symptomatology with some modifications to the scoring of the scale. And helplessness can be measured using the Helplessness subscale of the AHI. The PSEQ was an acceptable measure of self-efficacy and cognitive coping strategies can be measured with the CSQ. Rasch analysis highlighted lack of unidimensionality, disordered response thresholds and poor targeting in some measures commonly used for people with osteoarthritis.
Addiction, helplessness, and narcissistic rage.

PubMed

Dodes, L M

1990-07-01

In many cases addictive behavior serves to ward off a sense of helplessness or powerlessness via controlling and regulating one's affective state. Addicts have a vulnerability to feelings of powerlessness, which reflects a specific narcissistic impairment. The drive in addiction to re-establish a sense of power is, correspondingly, impelled by narcissistic rage. This rage gives to addiction some of its distinctive clinical properties. The narcissistic vulnerability in addicts is discussed. Several brief clinical cases are provided, and the view proposed is correlated with other psychoanalytic perspectives.
Alterations in brain-derived neurotrophic factor (BDNF) and its precursor proBDNF in the brain regions of a learned helplessness rat model and the antidepressant effects of a TrkB agonist and antagonist.

2015-12-01

Role of brain-derived neurotrophic factor (BDNF)-TrkB signaling in a learned helplessness (LH) model of depression was investigated. LH rats showed a reduction of BDNF in the medial prefrontal cortex (mPFC), CA3, and dentate gyrus (DG) of the hippocampus, whereas LH rats showed an increase in BDNF in the nucleus accumbens (NAc). Furthermore, levels of proBDNF, a BDNF precursor, were higher in the mPFC, but lower in the NAc, of LH rats. A single bilateral infusion of a TrkB agonist 7,8-DHF, but not a TrkB antagonist ANA-12, into the infralimbic (IL) of mPFC, DG, and CA3, but not the prelimbic (PrL) of mPFC, exerted antidepressant effects in LH rats. In contrast, a single bilateral infusion of ANA-12, but not 7,8-DHF, into the core and shell of NAc exerted antidepressant-like effects in LH rats, with more potent effects observed for the NAc core than for NAc shell. Interestingly, a single administration of 7,8-DHF (10mg/kg, i.p.) significantly improved a decreased phosphorylation of TrkB in the mPFC, CA3, and DG of LH rats. Additionally, ANA-12 (0.5mg/kg, i.p.) significantly improved an increased phosphorylation of TrkB in the NAc of LH rats. In conclusion, these results suggest that LH causes depression-like behavior by altering BDNF in the brain regions, and that proBDNF-BDNF processing and transport may be altered in the mPFC-NAc circuit of LH rats. Therefore, TrkB agonists might exert antidepressant effects by stimulating TrkB in the IL, CA3, and DG, while TrkB antagonists might exert antidepressant effects by blocking TrkB in the NAc.

To evaluate the association between learned helplessness (LH) and self-efficacy (SE) with disease activity, functional capacity, and level of pain in patients with rheumatoid arthritis (RA) and to compare LH and SE between patients in remission and patients with active disease. This multicentre, cross-sectional study included consecutive patients (aged ≥ 18 years) with RA according to 2010 American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) criteria. LH was measured by the Rheumatology Attitude Index (RAI), Spanish version; SE with the Arthritis Self-efficacy Scale (ASES), Spanish version; functional capacity with the Health Assessment Questionnaire, Argentinian version (HAQ-A); and perceived pain by the visual analogue scale (VAS). Disease activity was measured by the Clinical Disease Activity Index (CDAI). A total of 115 patients (82% females) with a mean (± sd) age of 58 ± 13 years were included. We found a significantly positive correlation between LH and perceived pain (p < 0.001), HAQ-A score (p < 0.001), and CDAI (p < 0.001) and a significantly negative correlation between SE and perceived pain (p < 0.001), HAQ-A score (p < 0.001), and CDAI (p < 0.001). We found greater levels of SE and lower grades of LH in patients in remission compared to those with active disease (median 76 vs. 58; p < 0.001 and 6 vs. 11; p < 0.001, respectively). LH and SE correlated significantly with disease activity, functional capacity, and perceived pain. Levels of SE were higher in patients in remission compared to those with active disease as opposed to levels of LH, which were lower in patients in remission compared to those with active disease. These results show that cognitive factors are related to disease activity and their modifications may have importance in the management of RA.

The experience of helplessness or abandonment during pregnancy affects the emotional state of women, hindering their disposition in taking care of themselves and their baby. The aim of this study was to understand the emotional experience arising from intra-family violence experienced by institutionally sheltered adolescent mothers and pregnant adolescents. This study is exploratory, descriptive, clinical and qualitive. Semi-structured interviews were conducted with a psychologist from the institution and with six adolescents in the institution: one pregnant girl and five mothers. The data showed that helplessness was experienced by participants both during their pregnancy and throughout their lives. The institution was found to be the only place of protection, care and support for adolescents in the puerperal pregnancy period. The adolescents' mothers had also experienced abandonment by either their family members or their partners and the adolescents themselves repeated this abandonment with their own children. This study concludes that violence has consequences for the lives of adolescents, causing immense suffering and a transgenerational repetition of violence, demanding greater prevention and intervention.
Helplessness and the exercise of power in the analytic session.

PubMed

Steiner, John

2011-02-01

This paper describes a clinical situation in which the analyst may be provoked to become overactive if he feels that his attempts to reach his patient are frustrated. Lack of tolerance for feelings of helplessness may leave him unable to sustain a receptive stance, and he may be drawn into enactments which lead to a power struggle with his patient. I will try to describe situations where such enactments were compelling. I will also consider what enabled me to extricate myself from the activity, at least intermittently, to re-establish an analytic attitude in which understanding and containment were priorities. From time to time I was able to recognize and accept my helplessness and relinquish my attempts to reach the patient. These moments of recognition led to a shift of atmosphere in which a feeling of sadness replaced the more familiar confrontational mood. In these sadder moods the patient felt I was more available, and he too seemed more able to contemplate loss. Theoretical ideas that enabled me to recognize some of the mechanisms at play included an understanding of narcissistic mechanisms, a recognition of previous ideas of power and dominance such as Freud's Bemächtigungstrieb, and the role of dominance in the resolution of the Oedipus complex. My previous work on the dread of humiliation allowed me to be sensitive to the way helplessness can come to be associated with being looked down on and humiliated.

Genetic ablation of the GluK4 kainate receptor subunit causes anxiolytic and antidepressant-like behavior in mice.

There is a clear link between dysregulation of glutamatergic signaling and mood disorders. Genetic variants in the glutamate receptor gene GRIK4, which encodes the kainate receptor subunit GluK4, alter the susceptibility for depression, bipolar disorder and schizophrenia. Here we demonstrate that Grik4(-/-) mice have reduced anxiety and an antidepressant-like phenotype. In the elevated zero-maze, a test for anxiety and risk taking behavior, Grik4(-/-) mice spent significantly more time exploring the open areas of the maze. In anxiogenic tests of marble-burying and novelty-induced suppression of feeding, anxiety-like behavior was consistently reduced in knockout animals. In the forced swim test, a test of learned helplessness that is used to determine depression-like behavior, knockout mice demonstrated significantly less immobility suggesting that Grik4 ablation has an antidepressant-like effect. Finally, in the sucrose preference test, a test for anhedonia in rodents, Grik4(-/-) mice demonstrated increased sucrose preference. Expression of the GluK4 receptor subunit in the forebrain is restricted to the CA3 region of the hippocampus and dentate gyrus regions where KARs are known to modulate synaptic plasticity. We tested whether Grik4 ablation had effects on mossy fiber (MF) plasticity and found there to be a significant impairment in LTP likely through a loss of KAR modulation of excitability of the presynaptic MF axons. These studies demonstrate a clear anxiolytic and antidepressant phenotype associated with ablation of Grik4 and a parallel disruption in hippocampal plasticity, providing support for the importance of this receptor subunit in mood disorders.

Bacopa monniera Wettst. (syn. Herpestis monniera L.; Scrophulariaceae) is a commonly used Ayurvedic drug for mental disorders. The standardized extract was reported earlier to have significant anti-oxidant effect, anxiolytic activity and improve memory retention in Alzheimer's disease. Presently, the standardized methanolic extract of Bacopa monniera (bacoside A - 38.0+/-0.9) was investigated for potential antidepressant activity in rodent models of depression. The effect was compared with the standard antidepressant drug imipramine (15 mg/kg, ip). The extract when given in the dose of 20 and 40 mg/kg, orally once daily for 5 days was found to have significant antidepressant activity in forced swim and learned helplessness models of depression and was comparable to that of imipramine.

Using learned helplessness (LH) model of depression, we measured protein expression of brain-derived neurotrophic factor (BDNF) pro-peptide, BDNF precursors (proBDNF and preproBDNF) in the brain regions of LH (susceptible) and non-LH rats (resilience). Expression of preproBDNF, proBDNF and BDNF pro-peptide in the medial prefrontal cortex of LH rats, but not non-LH rats, was significantly higher than control rats, although expression of these proteins in the nucleus accumbens of LH rats was significantly lower than control rats. This study suggests that regional differences in conversion of BDNF precursors into BDNF and BDNF pro-peptide by proteolytic cleavage may contribute to stress resilience.
A crossover trial evaluating an educational-behavioural joint protection programme for people with rheumatoid arthritis.

PubMed

Hammond, A; Lincoln, N; Sutcliffe, L

1999-05-01

Joint protection (JP) is a self-management technique widely taught to people with rheumatoid arthritis (RA). JP education aims to enable people with RA to reduce pain, inflammation, joint stress and reduce risks of deformity through using assistive devices and alternative movement patterns of affected joints to perform everyday activities. Previous studies evaluating JP education methods common in the UK have identified JP adherence is poor. A group education programme was developed using the Health Belief Model and Self-efficacy Theory. Strategies used to maximise JP adherence included goal-setting, contracting, modelling, homework programmes, motor learning theory, recall enhancing methods and mental practice. A crossover trial (n = 35) was conducted. Adherence with JP was measured using an objective observational test (the Joint Protection Behaviour Assessment). Significant improvements in use of JP were recorded at 12 and 24 weeks post-education (P < 0.01). No significant changes in measures of pain, functional disability, grip strength, self-efficacy or helplessness occurred post-education, although this may have been due to the small sample size recruited. In conclusion, JP adherence can be facilitated through the use of educational-behavioural strategies, suggesting this approach should be more widely adopted in clinical practice.
Perceptions of control in adults with epilepsy.

That psychosocial problems are extant in epilepsy is evidenced by a suicide rate among epileptic persons five times that of the general population and an unemployment rate estimated to be more than twice that of the population as a whole. External perceptions of control secondary to repeated episodes of seizure activity that generalize to the social sphere have been implicated as causes of these problems. The hypothesis that individuals who continue to have seizures become more and more external in perceptions of control was tested by a survey mailed to a sample of individuals with epilepsy in a metropolitan area of the Midwest. Dependent variables were, scores on instruments measuring locus of control and attributional style. The independent variable was a measure of seizure control based on present age, age at onset, and length of time since last seizure. Gender, socioeconomic status, and certain parenting characteristics were included as control variables, as they are also known to affect perceptions of control. Analysis by multiple regression techniques supported the study's hypothesis when perceptions of control was conceptualized as learned helplessness for bad, but not for good, events. The hypothesis was not confirmed when perceptions of control was conceptualized as either general or health locus of control.

This survey was performed to determine the relationship between the adherence to hypertension drug treatment and the perception of stress, depression, hypertension, and myocardial infarction. 300 patients with uncomplicated hyperten- sion from Rijeka, Croatia, were included (131 women, 169 men, mean age 53.5 years). Adherence to hypertension drug treatment as criterion, and the perception of stress, depression hypertension and myocardial infarction as prediclors were determined by self-assessment. Collected data were analysed using factor analysis, regression analysis, Kolmogorov-Smirnov test, chi2-test and t-test. The statistical significance was set at a probability rate of less than 5% (p < 0.05). 45.09% of women (p=0.479), and 64.08% of men (p = 0.032) were motivated to take antihypertensives. 55.79% of women (p = 0.382) and 64.78% of men (p = 0.028) had sufficient knowledge about drug treatment of hypertension. The positive predictors of motivation for taking antihypertensives were physiological disturbances and perceived potency of hypertension and the negative were perceived helplessness in stress control and negative thoughts and emotions. The positive predictors of knowledge about taking antihypertensives were perceived helplessness in stress control, perceived potency of hypertension and myocardial infarction and the negative predictors were perceived self-efficacy in stress control, physiological disturbances and evaluation of hypertension. Both the motivation as well as the knowledge about taking antihypertensives should be improved, especially in women. The perception of stress, depression, hypertension and myocardial infarction can be used to predict adherence to hypertension drug treatment.

Apelin is the endogenous ligand for the G-protein-coupled receptor (APJ). The localization of APJ in limbic structures suggests a potential role for apelin in emotional processes. However, the role of apelin in the regulation of stress-induced responses such as depression and memory impairment is largely unknown. In the present study, we evaluated the role of apelin-13 in the regulation of stress-induced depression and memory impairment in rats. We report that repeated intracerebroventricular injections of apelin-13 reversed behavioral despair (immobility) in the forced swim (FS) test, a model widely used for the selection of new antidepressant agents. Apelin-13 also reversed behavioral deficits (escape failure) in the learned helplessness test. The magnitude of the antiimmobility and anti-escape failure effects of apelin-13 was comparable to that of imipramine, a classic antidepressant used as a positive control. Rats exposed to FS stress showed memory performance impairment in the novel object recognition test, and this impairment was improved by apelin-13 treatment. Apelin-13 did not affect recognition memory performance in non-stressed rats. Furthermore, the pretreatment of LY294002 (PI3K inhibitors) or PD98059 (ERK1/2 inhibitor) blocked apelin-13-mediated activities in FS-stressed rats. These findings suggest that apelin-13 exerts antidepressant-like and recognition memory improving activities through activating PI3K and ERK1/2 signaling pathways in stressed rats.

Items from three locus of control (LOC) tests and the Beck Hopelessness Scale were administered to 197 college students. Factor analyses produced multiple factors for each LOC test, but the Beck scale proved to be unidimensional. Factor scales were constructed for each test, and scores were factor analyzed to discover common content. Each LOC test contained a salient dimension that described belief in luck, chance, or fate, and corresponding scales were well correlated. Internal control was the second common theme, with variations according to whether control was attributed to oneself or to people in general. The third common component expressed a personal helplessness or powerlessness. Each common factor was loaded by the Hopelessness Scale, which also correlated with all but one LOC factor scale.
[The potential of group II metabotropic glutamate receptor antagonists as a novel antidepressant].

Recently, abnormalities of glutamatergic transmission have been implicated in the pathophysiology of depression. Moreover, both ketamine, an NMDA receptor antagonist, and riluzole, a modulator of glutamatergic, transmission have been reported to be effective for the treatment of patients with treatment-refractory depression. Based on these findings, extensive studies to develop agents acting on glutamatergic transmission have been conducted. Glutamate receptors are divided into two main subtypes, ionotropic glutamate receptors and metabotropic glutamate (mGlu) receptors, both of which have subtypes. Of these, much attention has been paid to mGlu2/3 receptors. mGlu2/3 receptor antagonists such as MGS0039 and LY341495 have been reported to exert antidepressant effects in animal models of depression including the forced swim test, tail suspension test, learned helplessness paradigm, olfactory bulmectomy model and isolation rearing model, and to enhance serotonin release in the prefrontal cortex and dopamine release in the nucleus accumbens. Moreover, activation of AMPA receptor and mTOR signaling have been suggested to be involved in the antidepressant effects of mGlu2/3 receptor antagonists, as demonstrated in the actions of ketamine. Thus, mGlu2/3 receptor antagonists may share some neural networks with ketamine in exerting their antidepressant effects. In addition, the potential of other agents targeting glutamatergic transmission for novel antidepressants is being investigated.

Yacon (Smallanthus sonchifolius), a traditional food in the Andean diet, is attracting global attention for its medicinal properties, which are mainly because of its high content of non-digestible oligosaccharides. The purpose of this study is to evaluate the antidepressant-like effects of inulin-type oligosaccharides extracted from yacon (YOs) in behavioral models of depression. Behavioral despair models in mice including the tail suspension test (TST) and the forced swimming test (FST) were used to determine the effects of acute YOs administration. The locomotor activity was also explored to eliminate any false-positive activity. In addition, to further investigate the antidepressant-like effects of subchronic YOs administration, the learned helplessness (LH) paradigm in rats was performed. The results demonstrated that YOs (25, 50, or 100 mg/kg, p.o.) treatment significantly reduced the immobility time in the mouse TST and FST in a U-shaped, dose-dependent manner, and showed no stimulatory effect on the locomotor activity. Furthermore, subchronic YOs (25, 50, or 100 mg/kg, p.o.) treatment significantly reversed the escape deficits in LH rats, including an increased number of escape failures and prolonged escape latency. These findings suggest that the inulin-type oligosaccharides extracted from yacon may be a prospective natural source for antidepressants. Copyright © 2016 John Wiley & Sons, Ltd.

Stress-based animal models of depression: Do we actually know what we are doing?

Depression is one of the leading causes of disability and a significant health-concern worldwide. Much of our current understanding on the pathogenesis of depression and the pharmacology of antidepressant drugs is based on pre-clinical models. Three of the most popular stress-based rodent models are the forced swimming test, the chronic mild stress paradigm and the learned helplessness model. Despite their recognizable advantages and limitations, they are associated with an immense variability due to the high number of design parameters that define them. Only few studies have reported how minor modifications of these parameters affect the model phenotype. Thus, the existing variability in how these models are used has been a strong barrier for drug development as well as benchmark and evaluation of these pre-clinical models of depression. It also has been the source of confusing variability in the experimental outcomes between research groups using the same models. In this review, we summarize the known variability in the experimental protocols, identify the main and relevant parameters for each model and describe the variable values using characteristic examples. Our view of depression and our efforts to discover novel and effective antidepressants is largely based on our detailed knowledge of these testing paradigms, and requires a sound understanding around the importance of individual parameters to optimize and improve these pre-clinical models.

To investigate the association between helplessness, disability, and disease activity with health-related quality of life (HRQoL) in a multiethnic cohort of rheumatoid arthritis (RA) patients in Singapore. This cross-sectional study was conducted at Tan Tock Seng Hospital, Department of Rheumatology, Allergy and Immunology, from October 2010 to October 2011. All patients fulfilled the American College of Rheumatology 1987 criteria for RA. Socio-demographics, clinical, and patient-reported outcome (PRO) variables were collected. HRQoL outcomes were Short Form 36 (SF-36) physical and mental component summary (PCS and MCS) scores and Short Form 6 Dimensions (SF-6D) utilities. Stepwise multiple linear regression analyses were performed using HRQoL outcomes as dependent variables in separate models and with adjustment for helplessness (Rheumatology Attitudes Index, RAI), disability (Health Assessment Questionnaire, HAQ), and disease activity (Disease Activity in 28 joints) followed by socio-demographic, clinical, and PRO variables. Complete data were provided by 473 consenting subjects [mean (SD) age: 60.02 (11.04) years, 85 % female, 77 % Chinese]. After adjustment for all measured covariates, only RAI and HAQ scores remained significantly associated with SF-36 MCS (β: -0.9, p < 0.001; β: -7.0, p < 0.001) and SF-6D utilities (β: -0.005, p < 0.001; β: -0.081, p < 0.001), respectively, while only HAQ scores were significantly associated with SF-36 PCS (β: -7.7, p < 0.001). Interventions to address the sense of helplessness and to prevent or reduce disability could improve HRQoL of RA patients.

Antidepressants are used since 40 years. All presently used antidepressants have a slow onset of action and do not improve all patients; thus, there is an absolute need for new antidepressants. A variety of animal models, often based upon the monoaminergic theory of depressive disorders, has been used to screen the current antidepressants. In fact, the main focus of most of these animal models has been to predict the antidepressant potential i.e. to establish predictive validity. However, the evaluation of such animal models should also consider face validity, i.e. how closely the model resembles the human condition, and this should help to identify innovating medicines. Antidepressants, when taken by a healthy person, induce nothing more than side effects, unrelated to an action on mood, whereas they alleviate depressive symptomatology in depressed patients. We have speculated that genetically selected animal models would be closer to the human clinical situation than models based on standard laboratory strains. We have depicted here that marked differences exist between strains of mice in the amount of immobility i.e. "spontaneous helplessness" observed in the tail suspension test, a method used to screen potential antidepressants. We have studied the behavioural characteristics of mice selectively bred for spontaneous high or low immobility scores in the tail suspension test. Hopefully, these selectively bred lines will provide a novel approach to investigate behavioural, neurochemical and neuroendocrine correlates of antidepressant action.

Among the approaches to the demoralization syndrome, the one proposed by Kissane et al. is prevalent in the literature. These authors developed the Demoralization Scale (DS) to assess emotional distress, conceived as demoralization. To present the Spanish adaptation of the Demoralization Scale in palliative care patients, with a new and more comprehensive approach to its factorial structure. A cross-sectional study was carried out in 226 Spanish palliative care patients in three different settings: hospital, home care unit, and continued care unit. Outcome measures included the DS and the Hospital Anxiety and Depression Scale. Analyses comprised confirmatory factor analyses to test the original, German, and Irish structure of the DS, exploratory structural equation modeling (ESEM), estimations of internal consistency, and multivariate analyses of variance for criterion-related validity. The confirmatory factor analyses showed inappropriate fit for the previous structures when studied in the Spanish version of the DS. With ESEM, the best fitting structure was the five-factor solution, without item 18. Reliability results offered good estimations of internal consistency for all the dimensions except for sense of failure. Cronbach alpha coefficients were appropriate for the dimensions of loss of meaning (0.86), helplessness (0.79), disheartenment (0.88), and dysphoria (0.80), but low reliability was found for sense of failure (0.62). Convergent and discriminant validity showed positive correlations between demoralization, anxiety, and depression. Patients with higher levels of anxiety had higher scores on every dimension of demoralization, and those with higher levels of depression had higher scores on loss of meaning, disheartenment, and sense of failure, but not on dysphoria or helplessness. The Spanish adaptation of the DS has shown appropriate psychometric properties. It has been useful to differentiate between depression and the demoralization syndrome, pointing to helplessness and dysphoria as unique characteristics of demoralized palliative care patients.

The uses of hopelessness.

Bennett, M I; Bennett, M B

1984-04-01

If most emotional problems, like most medical problems, are caused by bad luck as well as by factors over which man has control, then those who suffer from such problems must accept a burden of helplessness. When patients and their families overuse theories of causality to avoid accepting their helplessness and to create an illusory sense of human control, unjust assignment of responsibility and excessive expectations for change may erode self-esteem and make change more difficult. The authors present examples of interventions that challenge the overuse of theories of causality. Although these interventions aroused hopelessness, they also fostered realistic hope and change.
Depression-like behaviour in mice is associated with disrupted circadian rhythms in nucleus accumbens and periaqueductal grey.

PubMed

Landgraf, Dominic; Long, Jaimie E; Welsh, David K

2016-05-01

An association between circadian rhythms and mood regulation is well established, and disturbed circadian clocks are believed to contribute to the development of mood disorders, including major depressive disorder. The circadian system is coordinated by the suprachiasmatic nucleus (SCN), the master pacemaker in the hypothalamus that receives light input from the retina and synchronizes circadian oscillators in other brain regions and peripheral tissues. Lacking the tight neuronal network that couples single-cell oscillators in the SCN, circadian clocks outside the SCN may be less stable and more susceptible to disturbances, for example by clock gene mutations or uncontrollable stress. However, non-SCN circadian clocks have not been studied extensively in rodent models of mood disorders. In the present study, it was hypothesized that disturbances of local circadian clocks in mood-regulating brain areas are associated with depression-like behaviour in mice. Using the learned helplessness procedure, depression-like behaviour was evoked in mice bearing the PER2::LUC circadian reporter, and then circadian rhythms of PER2 expression were examined in brain slices from these mice using luminometry and bioluminescence imaging. It was found that helplessness is associated with absence of circadian rhythms in the nucleus accumbens and the periaqueductal grey, two of the most critical brain regions within the reward circuit. The current study provides evidence that susceptibility of mice to depression-like behaviour is associated with disturbed local circadian clocks in a subset of mood-regulating brain areas, but the direction of causality remains to be determined. © 2015 Federation of European Neuroscience Societies and John Wiley & Sons Ltd.

The current paper presents a systematic review of this theory including its subsequent elaborations (Rose and Abramson’s [1992] developmental elaboration, Abela and Sarin’s [2002] weakest-link approach, Panzarella, Alloy, and Whitehouse’s [2006] expansion of the hopelessness theory, and the hopelessness theory of suicide [Abramson et al., 2000]), followed by recommendations for future study. Although empirical support was consistently found for several major components of the hopelessness theory, further work is required assessing this theory in relation to clinically significant phenomena. Among the most significant hindrances to advancement in this area is the frequent conceptual confusion between the hopelessness theory and the reformulated learned helplessness theory. PMID:26709338

Methods learnt by nursing and midwifery students' such as communication skills, optimisim and coping with stress would be used in their profeesional life. It is very important to promote their positive thinking and communication skills to raise coping with stress. This cross sectional study was performed to examine the nursing and midwifery students' communication skills and optimistic life orientation and its correlation with coping strategies with stress. The study population included 2572 students who were studying in departments of nursing and midwifery in Istanbul. The sample was included 1419 students. Three questionnaires including Communication Skills Test, Life Orientation Test and Ways of Coping Inventory were used for data collection. The data were evaluated by calculating frequency, percentage, arithmetic mean, standard deviation and Pearson correlation coefficient. Students' total mean score from the Communication Skills Scale was 165.27 ± 15.39 and for the Life Orientation Test was 18.51 ± 4.54. There was a positive correlation between their Life Orientation scores and the scores for self confidence (r = 0.34, P < 0.001), optimistic approach (r = 0.42, P < 0.001), and seeking social help (r = 0.17, P < 0.001). Also there was a significant positive correlation between Communication skill scores and self confidence (r = 0.46, P < 0.001), optimistic (r = 0.37, P < 0.001) and seeking social help approaches (r = 0.29, P < 0.001), but there was a significant negative correlation between communication skill scores and scores for helpless (r = -0.29, P < 0.001) and submissive approaches (r = -0.36, P < 0.001). As scores of students in optimistic life orientation and communication skills increased self confidence approach, optimistic, and social support seeking scores increased, whereas helpless, and submissive scores decreased.

The study assesses the association between religiosity and coping style with the outcome of depression and diabetes. Using a simple random sampling, we recruited 112 participants with diabetes and an equal number with depression consecutively, matching for gender. Religiosity was determined using Religious Orientation Scale (revised) (ROS-R), coping styles with Brief Religious Coping (Brief RCOPE) scale and Mental Adjustment to Cancer (MAC) scale (adapted). Primary and secondary outcomes were evaluated using Sheehan's Disability Scale (SDS) and Becks Depression Inventory-II (BDI-II) respectively. Among participants with diabetes, BDI-II total scores correlated negatively with ROS-R Extrinsic Social (r = -0.2, P < 0.05) and Fighting Spirit (r = -0.3, P < 0.05) but correlated positively with Helplessness/Hopelessness (r = 0.3, P < 0.05) and Brief RCOPE Negative (r = 0.4, P < 0.05). SDS global scores correlated positively with Helplessness/Hopelessness (r = 0.3, P < 0.05) and Brief RCOPE Negative (r = 0.4, P < 0.05). Among participants with depression, BDI-II total scores correlated negatively with Intrinsic religiosity (r = -0.2, P < 0.05) and Fighting Spirit (r = -0.4, P < 0.05) but correlated positively with Helplessness/Hopelessness (r = 0.6, P < 0.05) and Brief RCOPE Negative (r = 0.7, P < 0.05). SDS global scores correlated negatively with Intrinsic religiosity (r = -0.2, P < 0.05) and Fighting Spirit (r = -0.3, P < 0.05) but correlated positively with Helplessness/Hopelessness (r = 0.5, P < 0.05) and Brief RCOPE Negative (r = 0.4, P < 0.05). High intrinsic and extrinsic religiosities are likely to be associated with positive coping skills and better treatment outcome in patients with depression or diabetes. © 2015 John Wiley & Sons A/S.

Compared with white individuals and men, black individuals and women show a lower tolerance for experimental pain stimuli. Previous studies suggest that pain catastrophizing is important in this context, but little is known about which components of catastrophizing contribute to these race and sex differences. The purpose of the current study was to examine the individual components of catastrophizing (rumination, magnification, and helplessness) as candidate mediators of race and sex differences in experimental pain tolerance. Healthy undergraduates (N = 172, 74% female, 43.2% black) participated in a cold pressor task and completed a situation-specific version of the Pain Catastrophizing Scale. Black and female participants showed a lower pain tolerance than white (P < .01, d = .70) and male (P < .01, d = .55) participants, respectively. Multiple mediation analyses indicated that these race and sex differences were mediated by the rumination component of catastrophizing (indirect effect = -7.13, 95% confidence interval (CI), -16.20 to -1.96, and 5.75, 95% CI, .81-15.57, respectively) but not by the magnification (95% CI, -2.91 to 3.65 and -1.54 to 1.85, respectively) or helplessness (95% CI, -5.53 to 3.31 and -.72 to 5.38, respectively) components. This study provides new information about race and sex differences in pain and suggests that treatments targeting the rumination component of catastrophizing may help mitigate pain-related disparities. This study suggests that differences in pain-related rumination, but not magnification or helplessness, are important contributors to race and sex differences in the pain experience. Interventions that target this maladaptive cognitive style may help reduce disparities in pain. Copyright © 2016 American Pain Society. Published by Elsevier Inc. All rights reserved.

Many studies link depression to an increase in the excitatory-inhibitory ratio in the forebrain. Presynaptic alterations in a shared pathway of the glutamate/gamma-aminobutyric acid (GABA) cycle may account for this imbalance. Evidence suggests that decreased vesicular glutamate transporter 1 (VGLUT1) levels in the forebrain affect the glutamate/GABA cycle and induce helpless behavior. We studied decreased VGLUT1 as a potential factor enhancing a depressive-like phenotype in an animal model. Glutamate and GABA synthesis as well as oxidative metabolism were studied in heterozygous mice for the VGLUT1+/- and wildtype. The regulation of neurotransmitter levels, proteins involved in the glutamate/GABA cycle, and behavior by both genotype and chronic mild stress (CMS) were studied. Finally, the effect of chronic imipramine on VGLUT1 control and CMS mice was studied. VGLUT1+/- mice showed increased neuronal synthesis of glutamate; decreased cortical and hippocampal GABA, VGLUT1, and excitatory amino acid transporter 1 (EAAT1) as well as helplessness and anhedonia. CMS induced an increase of glutamate and a decrease of GABA, the vesicular GABA transporter (VGAT), and glutamic acid decarboxylase 65 (GAD65) in both areas and led to upregulation of EAAT1 in the hippocampus. Moreover, CMS induced anhedonia, helplessness, anxiety, and impaired recognition memory. VGLUT1+/- CMS mice showed a combined phenotype (genotype plus stress) and specific alterations, such as an upregulation of VGLUT2 and hyperlocomotion. Moreover, an increased vulnerability to anhedonia and helplessness reversible by chronic imipramine was shown. These studies highlight a crucial role for decreased VGLUT1 in the forebrain as a biological mediator of increased vulnerability to chronic mild stress.
Behavioral and biochemical effects of the antidepressant bupropion (Wellbutrin): evidence for selective blockade of dopamine uptake in vivo.

PubMed

Cooper, B R; Hester, T J; Maxwell, R A

1980-10-01

Bupropion (BW 323U; Wellbutrin), a novel compound with antidepressant effects in man, was found to reduce immobility in an "experimental helplessness" forced swimming antidepressant test in rats as did imipramine and amitriptyline. Higher doses produced elevated locomotor activity in an automated open field and produced stereotyped sniffing which was contrasted with apomorphine. When bupropion or desmethylimipramine was given before intracisternal injections of 6-hydroxydopamine, bupropion produced a dose-related selective antagonism of the destruction of dopamine neurons, while under the same conditions, desmethylimipramine produced a dose-related selective antagonism of the destruction of noradrenergic neurons. Studies in which the dose of bupropion and the dose of 6-hydroxydopamine were varied revealed that a dose-related selective antagonism of dopamine depletion by 6-hydroxydopamine occurred when doses up to and including 50 mg/kg i.p. to bupropion were administered. Some antagonism of norepinephrine depletion also occurred at 100 mg/kg of bupropion i.p. Bupropion also selectively reversed the dopamine depletion produced by alpha-methyl-m-tyrosine, a finding which is consistent with the view that bupropion is a dopamine uptake inhibitor in vivo. The importance of dopamine systems for the behavioral effects of bupropion were also studied. When the locomotor stimulant effects of bupropion were tested in rats with chronic destruction of dopamine neurons produced by 6-hydroxydopamine, bupropion failed to elevate locomotor activity. Rats treated with procedures using 6-hydroxydopamine to produce relatively selective norepinephrine depletions responded to bupropion with locomotor activity stimulation like controls. Rats with similar depletions of either dopamine or norepinephrine were also tested for the ability of low doses of bupropion to reduce immobility in the "experimental helplessness" forced swim antidepressant test. Prior destruction of dopamine neurons prevented activity of bupropion in this test. Results indicate that bupropion is a selective dopamine uptake inhibitor in vivo and that dopaminergic systems play an important role in its central nervous system pharmacology.
Illness cognitions as a pathway between religiousness and subjective health in chronic cardiac patients.

PubMed

Karademas, Evangelos C

2010-03-01

The aim of this study was to examine the role of illness cognitions as a possible pathway between religiousness and subjective health in chronic illness. A sample of 135 chronic cardiac patients completed questionnaires about intrinsic religiousness, frequency of church service attendance, basic illness cognitions (i.e., helplessness, illness acceptance, perceived benefits), and physical and emotional well-being. According to the results, religiousness was significantly associated with subjective health. However, this relationship was indirect, with helplessness and illness acceptance serving as mediators between intrinsic religiousness and health. This finding is significant for understanding the complex relation of religiousness to chronic patients' well-being.

Object-related vs. narcissistic depression: a theoretical and clinical study.

PubMed

Glazer, M W

1979-01-01

This paper has focused on the sense of helplessness as an essential component of a depressive reaction. By inference, a sense of mastery and ability to achieve goals seems essential for a sense of well-being. Both patients presented here revealed infantile fantasies that hampered their exercising this mastery, and the path to well-being was the analysis of these fantasies. The treatment plans differed, though, in the locus of the fantasies. In an object-related depression such as Mr. Janson's, the fantasy involved the inhbition of functioning--that is, the inability to express aggression--and the treatment aimed at removing the inhibition. In a narcissistic depression such as Miss Gaynor's, the helplessness was not due to inhibited functioning per se. Rather, her goals were unrealistic, unattainable, and based on unconscious fantasies. Here the aim of treatment was the development of more reality-adapted and attainable objectives and the concommitant internalization of a more realistic sense of her own worth. Thus the common denominator in both depressive reactions was a sense of helplessness, and the path toward increased self-esteem was by way of the development of a sense of mastery and competence.
II Spatial metaphors and somatic communication: the embodiment of multigenerational experiences of helplessness and futility in an obese patient.

PubMed

2013-06-01

This paper explores the analysis of an obese woman who came to experience her flesh as a bodying forth of personal and multigenerational family and cultural experiences of helplessness. The paper discusses the ideas and images that formed the basis of how I engaged with these themes as they presented countertransferentially. My thesis is that clinical approaches which draw on spatial metaphors for the psyche offer valuable tools for working with people whose inner world expresses itself somatically because such metaphors can be used to engage simultaneously with the personal, cultural, and ancestral dimensions of these unconscious communications. The paper builds on Jung's view of the psyche as comprised of pockets of inner otherness (complexes), on Redfearn's image of psyche as landscape-like and on Samuels' thinking on embodied countertransference and on the political psyche. It also draws on Butler's work on the body as a social phenomenon and on the theme of being a helpless non-person or nobody as explored in Tom Stoppard's play Rosencrantz and Guildenstern are Dead which retells Shakespeare's Hamlet from the perspective of two of the play's 'bit' characters. © 2013, The Society of Analytical Psychology.
Depression and helplessness-induced cognitive deficits in the aged.

Sixty-six community-residing elderly (mean age = 72.5) were categorized as depressed (mean = 11.3) or nondepressed (mean = 3.9) based on Beck Depression Inventory scores. After a pre-test battery measuring short-term memory and crystallized/fluid intelligence, the subjects responded to a word association task, disguised as a test of interpersonal empathy, under response dependent or response independent reinforcement conditions, or were assigned to a no treatment control. A post-test battery of alternate forms followed. Four of seven measures showed significant pre- to post-test declines in performance. For two of these four, response dependent reinforcement prevented otherwise significant declines. With pre-test differences statistically controlled, depression produced significant post-test deficits in three measures. Response dependent reinforcement eliminated this depression deficit in one measure. The results indicate that depression may exacerbate fatigue effects for the elderly and response dependent reinforcement may prevent fatigue-caused deficits in short-term memory.

Prenatal ethanol exposure is associated with an increased incidence of depressive disorders in patient populations. However, the mechanisms that link prenatal ethanol exposure and depression are unknown. Several recent studies have implicated reduced brain-derived neurotrophic factor (BDNF) levels in the hippocampal formation and frontal cortex as important contributors to the etiology of depression. In the present studies, we sought to determine whether prenatal ethanol exposure is associated with behaviors that model depression, as well as with reduced BDNF levels in the hippocampal formation and/or medial frontal cortex, in a mouse model of fetal alcohol spectrum disorder (FASD). Compared to control adult mice, prenatal ethanol-exposed adult mice displayed increased learned helplessness behavior and increased immobility in the Porsolt forced swim test. Prenatal ethanol exposure was associated with decreased BDNF protein levels in the medial frontal cortex, but not the hippocampal formation, while total BDNF mRNA and BDNF transcripts containing exon III, IV or VI were reduced in both the medial frontal cortex and the hippocampal formation of prenatal ethanol-exposed mice. These results identify reduced BDNF levels in the medial frontal cortex and hippocampal formation as potential mediators of depressive disorders associated with FASD. PMID:18558427

Currently approved antidepressant drug treatment typically takes several weeks to be effective. The noncompetitive N-methyl-d-aspartate (NMDA) receptor antagonist ketamine has shown efficacy as a rapid-acting treatment of depression, but its use is associated with significant side effects. We assessed effects following blockade of the glycineB co-agonist site of the NMDA receptor, located on the GluN1 subunit, by the selective full antagonist 7-chloro-kynurenic acid (7-Cl-KYNA), delivered by systemic administration of its brain-penetrant prodrug 4-chlorokynurenine (4-Cl-KYN) in mice. Following administration of 4-Cl-KYN, 7-Cl-KYNA was promptly recovered extracellularly in hippocampal microdialysate of freely moving animals. The behavioral responses of the animals were assessed using measures of ketamine-sensitive antidepressant efficacy (including the 24-hour forced swim test, learned helplessness test, and novelty-suppressed feeding test). In these tests, distinct from fluoxetine, and similar to ketamine, 4-Cl-KYN administration resulted in rapid, dose-dependent and persistent antidepressant-like effects following a single treatment. The antidepressant effects of 4-Cl-KYN were prevented by pretreatment with glycine or the α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor antagonist 2,3-dihydroxy-6-nitro-7-sulfamoyl-benzo[f]quinoxaline-2,3-dione (NBQX). 4-Cl-KYN administration was not associated with the rewarding and psychotomimetic effects of ketamine, and did not induce locomotor sensitization or stereotypic behaviors. Our results provide further support for antagonism of the glycineB site for the rapid treatment of treatment-resistant depression without the negative side effects seen with ketamine or other channel-blocking NMDA receptor antagonists.

Brief Social Isolation in the Adolescent Wistar-Kyoto Rat Model of Endogenous Depression Alters Corticosterone and Regional Monoamine Concentrations.

Shetty, Reshma A; Sadananda, Monika

The Wistar-Kyoto rat (WKY) model has been suggested as a model of adult and adolescent depression though face, predictive and construct validities of the model to depression remain equivocal. The suitability of the WKY as a diathesis model that tests the double-hit hypothesis, particularly during critical periods of brain and behavioural development remains to be established. Here, effects of post-weaning social isolation were assessed during early adolescence (~30pnd) on behavioural despair and learned helplessness in the forced swim test (FST), plasma corticosterone levels and tissue monoamine concentrations in brain areas critically involved in depression, such as prefrontal cortex, nucleus accumbens, striatum and hippocampus. Significantly increased immobility in the FST was observed in socially-isolated, adolescent WKY with a concomitant increase in corticosterone levels over and above the FST-induced stress. WKY also demonstrated a significantly increased release and utilization of dopamine, as manifested by levels of metabolites 3,4-dihydroxyphenylacetic acid and homovanillic acid in nucleus accumbens, indicating that the large dopamine storage pool evident during adolescence induces greater dopamine release when stimulated. The serotonin metabolite 5-hydroxy-indoleacetic acid was also significantly increased in nucleus accumbens, indicating increased utilization of serotonin, along with norepinephrine levels which were also signficantly elevated in socially-isolated adolescent WKY. Differences in neurochemistry suggest that social or environmental stimuli during critical periods of brain and behavioural development can determine the developmental trajectories of implicated pathways.

Depressive-like forms of waking inactivity have been recently observed in laboratory primates and horses. We tested the hypotheses that being awake but motionless within the home-cage is a depression-like symptom in mice, and that in impoverished housing, it represents an alternative response to stereotypic behaviour. We raised C57BL/6 ('C57') and DBA/2 ('DBA') females to adulthood in non-enriched (n=62 mice) or enriched (n=60 mice) cages, observing home-cage behaviour during the active (dark) phases. We predicted that being still but awake would be reduced by environmental enrichment; more pronounced in C57s, as the strain most prone to learned helplessness; negatively related to stereotypic behaviour; and positively related to immobility in Forced Swim Tests (FST). Compared to enriched mice, non-enriched subjects did spend more time spent being inactive but awake, especially if they displayed relatively little stereotypic behaviour. C57 mice also spent more time awake but motionless than DBAs. Furthermore, even after statistically controlling for housing type and strain, this behaviour very strongly tended to predict increased immobility in the FST, while high levels of stereotypic behaviours in contrast predicted low immobility in the FST. Being awake but motionless is thus a reaction to non-enriched housing that seems to be an alternative to stereotypic behaviour, and could reflect depression-like states.

Previous studies have demonstrated that leptin and its receptors (LepRb) in the central nervous system play an important role in regulating depression- and anxiety-related behaviors. However, the physiological functions of LepRb in specific brain regions for mediating different emotional behaviors remain to be defined. In this study, we examined the behavioral effects of LepRb ablation in the adult hippocampus using a series of behavioral paradigms for assessing depression- and anxiety-related behaviors. Targeted deletion of LepRb was achieved using the Cre/loxP site-specific recombination system through bilateral stereotaxic delivery of an adeno-associated virus expressing Cre-recombinase (AAV-Cre) into the dentate gyrus of adult mice homozygous for a floxed leptin receptor allele. AAV-Cre-mediated deletion of the floxed region of LepRb was detected 2 weeks after injection. In accordance with this, leptin-stimulated phophorylation of Akt was attenuated in the hippocampus of AAV-Cre injected mice. Mice injected with AAV-Cre displayed normal locomotor activity and anxiety-like behavior, as determined in the elevated plus maze, light dark box and open field tests, but showed increased depression-like behaviors in the tail suspension, sucrose preference and learned helplessness tests. Taken together, this data suggests that deletion of LepRb in the adult hippocampus is sufficient to induce depression-like behaviors. Our results support the view that leptin signaling in the hippocampus may be essential for maintaining positive mood states and active coping to stress. PMID:22932068

How medical residents' experiences with care for dying patients affect their emotional well-being, their learning outcomes, and the formation of their professional identities is not fully understood. We examine residents' emotional states and learning occurring during the provision of care to dying patients and specifically discuss the impact of providing end-of-life (EOL) care on professional identity formation. Semi-structured interviews were conducted with 13 residents who had graduated in the last 3 to 5 years. Thematic theoretical analysis was applied, and key themes were developed based on Kolb's experiential learning cycle. Eight key themes emerged from the analysis. The residents experienced dilemmas in confronting the reality of medical uncertainty as well as a disruption of emotional state and self-efficacy. Although the residents felt a sense of helplessness and guilt, they were able to reflect on strategies for handling medical care that focused on patients and that required a truly sincere attitude. They also contemplated the importance of palliative care and communication with patients, patients' family members and medical staff. Building on these experiences, the residents rebuilt a sense of awareness that allowed them to directly engage with the type of medical care that they are likely to be called upon to perform in the future as the population continues to age. This study revealed Japanese residents' perceptions, emotions and learning processes in caring for dying patients by applying Kolb's experiential learning theory. The findings of this study may illuminate valuable pieces of knowledge for future education in EOL care.

Stress renders an individual to experience mental pressure and exhaustion which brings about feelings of anxiety, depression, anger and/or other negative emotions. Depression affects a person's state of mind, behaviour, health and is often associated with suicide. The use of anti-depressant drugs as therapeutic agents is associated with symptoms such as, delayed onset of action, side-effects, drug-drug and dietary interactions, sexual dysfunction, cardiac toxicity, etc. Thus, there is need to target these issues and improve current treatment options. Medicinal plants have long been used in discovering novel treatment strategies and compounds with promising roles in treating various disease conditions. There has been an increase, worldwide, in the use of medicinal plants and herbs for developing nutraceuticals for treatment of depression and other psychiatric disorders. Medicinal plants in their natural forms are valuable as they are rich in various phytochemical compounds. These phytochemical compounds have pharmacological roles in treating various diseases conditions; apart from being widely available in nature and commercially beneficial. The phytochemical compounds in plants are constantly being explored through various experimental studies to determine the molecular basis of how medicinal plants work in relation to drugs and diseases and to develop neutraceuticals for improving conditions. This review summarizes 110 medicinal plants and their phytochemical constituents that have been shown to possess anti-depressant activity. This review also highlights the various mechanisms of anti-depressant action of some of these plants and their plant parts like roots, stem, leaves, flowers, fruit or whole plant; phytochemical compounds showing anti-depressant activity such flavanoids, steroids, saponins, sugars, lectins, alkaloids, etc.; and various anti-depressant screening models used such as tail suspension test, forced swim test, chronic unpredictable stress test, sucrose preference test, monoamine oxidase inhibition assay, learned helplessness test, open field test, hole board test, etc. However, mechanistic evaluation of many of these plants still needs to be investigated and explored.

We conducted a prospective cohort study in Japan to investigate associations between negative psychological aspects and cancer survival. Between July 1999 and July 2004, a total of 1178 lung cancer patients were enrolled. The questionnaire asked about socioeconomic variables, smoking status, clinical symptoms, and psychological aspects after diagnosis. Negative psychological aspects were assessed for the subscales of helplessness/hopelessness and depression. Clinical stage, performance status (PS), and histologic type were obtained from medical charts. The subjects were followed up until December 2004, and 686 had died. A Cox regression model was used to estimate the hazards ratio (HR) of all-cause mortality. After adjustment for socioeconomic variables and smoking status in addition to sex, age, and histologic type, both helplessness/hopelessness and depression subscales showed significant linear positive associations with the risk of mortality (p for trend<0.001 for both). However, after adjustment for clinical state variables in addition to sex, age, and histologic type, these significant linear positive associations were no longer observed (p for trend=0.41 and 0.26, respectively). Our data supported the hypothesis that the association between helplessness/hopelessness and depression and the risk of mortality among lung cancer patients was largely confounded by clinical state variables including clinical stage, PS, and clinical symptoms.

The Turkish version of the Perceived Stress Scale (T-PSS-10) measures the extent to which situations in one's life are appraised as stressful. The purpose of this study was to evaluate the measurement structure of T-PSS-10. Two-hundred and thirty-five Turkish university students (93 men and 142 women) completed the T-PSS-10, the Patient Health Questionnaire-9 (PHQ-9), the General Anxiety Disorder 7-Item Scale (GAD-7), and the Inventory of Common Problems (ICP). Confirmatory factor analysis results indicated that a one-factor model did not fit the data, whereas a two-factor correlated model (stress related self-efficacy beliefs, stress related feelings of helplessness) provided a better fit between the model and the data. Significant moderate correlations were found for the stress-related self-efficacy beliefs and stress-related feelings of helplessness factors with depression, anxiety, academic difficulty, relationship problems and health problems. The internal consistency reliability coefficients for the stress-related self-efficacy beliefs and stress-related feelings of helplessness factors were 0.68 and 0.85, respectively. This study provided support for the reliability and validity of T-PSS-10 suggesting that it can be used as a screening instrument by health professionals working with Turkish college students.

We assessed the psychometric properties of a Singaporean Chinese version of the EQ-5D, a health-related quality of life (HRQoL) instrument. Consecutive outpatients with rheumatic diseases seen for routine follow-up consultations at the National University Hospital, Singapore were interviewed twice within 2 weeks using a standardised questionnaire containing the EQ-5D, the Short-Form 36 Health Survey (SF-36), the Learned Helplessness Subscale, a pain Visual Analogue Scale (VAS) and assessing demographic and psychosocial characteristics. To assess the validity of the EQ-5D, 13 hypotheses relating the EQ-5D self-classifier (5 dimensions) or visual analogue scale (EQ-VAS) to SF-36 scores or other variables were examined using the Mann-Whitney U test, Kruskal-Wallis or Spearman's correlation coefficient. Test-retest reliability was assessed using Cohen's kappa. Forty-eight subjects were studied (osteoarthritis: 16; rheumatoid arthritis: 22; systemic lupus erythematosus: 8; spondyloarthropathy: 2; female: 93.8%; mean age: 56.4 years). Seven of 13 a-priori hypotheses relating EQ-5D to external variables were fulfilled, supporting the validity of the EQ-5D. For example, subjects reporting moderate or extreme problems for EQ-5D dimensions generally had lower median SF-36 scores than those without such problems. Cohen's kappa for test-retest reliability of the self-classifier ranged from 0.41 to 1.00 (n = 42; median interval: 7 days, interquartile range: 7 to 11 days). The Singaporean Chinese EQ-5D self-classifier appears to be a valid measure of HRQoL in Singaporeans with rheumatic diseases; however, the reliability of the EQ-VAS requires further investigation. These data provide a basis for further studies of the Singaporean Chinese EQ-5D.

Clinically depressed individuals respond to different types of antidepressants, suggesting that different neurobiological mechanisms may be responsible for their depression. However, animal models to characterize this are not yet available. We induced depressive-like behaviors in rats using 2 different chronic stress models: restraint in small cages or immobilization in adaptable plastic cones. Both models increased anxiety responses evaluated by novelty-suppressed feeding and the elevated plus-maze; increased learned helplessness evaluated by the tail suspension and forced swimming tests; and increased anhedonia evaluated by the sucrose preference test. We assessed the ability of 2 different types of antidepressants to ameliorate depressive-like behaviors. We administered the serotonin reuptake inhibitor fluoxetine or the noradrenaline reuptake inhibitor reboxetine once daily for 28 days to rats that received either chronic restraint or immobilization stress, or no stress. Behavioral analysis revealed that fluoxetine ameliorated depressive-like behaviors when induced by chronic restraint stress, whereas reboxetine ameliorated these behaviors when induced by chronic immobilization stress. To further test biological differences between both models, we evaluated the levels of Aldolase C, an enzyme expressed by forebrain astrocytes that is regulated by antidepressant treatment, in the cerebrospinal fluid: chronic restraint stress, but not immobilization stress, increased the levels of Aldolase C. Moreover, the presence of astrocyte-derived Aldolase C-GFP in the cerebrospinal fluid indicates its central origin. Two stress paradigms induced depressive-like behaviors that were sensitive to different antidepressant treatments. Biomarkers such as Aldolase C could help determine optimal antidepressant treatments for clinically depressed patients. © The Author 2015. Published by Oxford University Press on behalf of CINP.

Mild traumatic brain injury (mTBI) accounts for the majority of all brain injuries and affected individuals typically experience some extent of cognitive and/or neuropsychiatric deficits. Given that repeated mTBIs often result in worsened prognosis, the cumulative effect of repeated mTBIs is an area of clinical concern and on-going pre-clinical research. Animal models are critical in elucidating the underlying mechanisms of single and repeated mTBI-associated deficits, but the neurobehavioral sequelae produced by these models have not been well characterized. Thus, we sought to evaluate the behavioral changes incurred after single and repeated mTBIs in mice utilizing a modified impact-acceleration model. Mice in the mTBI group received 1 impact while the repeated mTBI group received 3 impacts with an inter-injury interval of 24h. Classic behavior evaluations included the Morris water maze (MWM) to assess learning and memory, elevated plus maze (EPM) for anxiety, and forced swim test (FST) for depression/helplessness. Additionally, species-typical behaviors were evaluated with the marble-burying and nestlet shredding tests to determine motivation and apathy. Non-invasive vibration platforms were used to examine sleep patterns post-mTBI. We found that the repeated mTBI mice demonstrated deficits in MWM testing and poorer performance on species-typical behaviors. While neither single nor repeated mTBI affected behavior in the EPM or FST, sleep disturbances were observed after both single and repeated mTBI. Here, we conclude that behavioral alterations shown after repeated mTBI resemble several of the deficits or disturbances reported by patients, thus demonstrating the relevance of this murine model to study repeated mTBIs.

Objective: The current study was designed to explore anxiolytic, antidepressant, and antistress actions of Cinnamomum tamala (CT) leaves (aqueous extract) in rats. Materials and Methods: Behavioral procedures of anxiety, depression, and stress were assessed in rats. CT (100, 200, and 400 mg/kg) was given once a daily for 7 days via oral route and the efficacy was matched by those elicited by lorazepam (1 mg/kg, p.o.), imipramine (10 mg/kg, p.o.), and Withania somnifera (100 mg/kg, p.o.) for anxiolytic, antidepressant, and antistress studies, respectively. Standard drugs were given 1 time, 30 min preceding the behavioral trials. Results: One-way analysis of variance followed by Newman–Keuls multiple comparison test was employed to analyze the results. P < 0.05 was considered statistically significant as compared to control. CT at 400 mg/kg produced an antianxiety effect equivalent to lorazepam, in the elevated plus maze, open field, and social interaction tests among selected doses of the CT. CT at 400 mg/kg also induced an antidepressant activity similar to imipramine, in the behavioral despair, learned helplessness test, and tail suspension among selected doses of the CT. Moreover, CT at 400 mg/kg produced a significant antistress effect comparable to W. somnifera in water immersion-restraint stress by decreasing ulcer index, adrenal gland weight, and by normalizing the plasma levels of corticosterone, glucose, cholesterol, and triglyceride levels when related to stress control. Conclusion: The study shows that among the different CT doses, CT at 400 mg/kg possesses significant anxiolytic, antidepressant, and anti-stress effects and has therapeutic beneficial for the management of psychological ailments.

"Straight Talk," a monthly newspaper produced by Uganda's Ministry of Information, provides advice to young people about sexuality, relationships, and sexually transmitted diseases, including human immunodeficiency virus (HIV). The tabloid is inserted in the daily government newspaper, "New Vision," which has a circulation of 40,000; another 30,000 copies are distributed to secondary schools and nongovernmental organizations. The newspaper began in 1993 as part of the media campaign of Safeguard Youth from Acquired Immunodeficiency Syndrome (AIDS). Each issue publishes articles by and interviews with young people, dozens of letters from readers, and columns by health care professionals. The content seeks to demystify sex, challenge gender-based stereotypes, and encourage real friendships between girls and boys. There is strong peer support for postponing sex. A recent issue included a contest for the best story about sexual boasting and pressure. One article noted that boys and girls learn separate rules of sexual behavior that resemble scripts in a play. Another analyzed passages from popular novels depicting men as strong and forceful and women as helpless and submissive. The publication also encourages dialogue between parents and children about sex. Many schools have formed clubs that discuss issues raised in the publication.
Affect-related related behaviors in mice selectively bred for high and low voluntary alcohol consumption

There is considerable evidence for the existence of comorbidity between alcohol-use disorders and depression in humans. One strategy to elucidate hereditary factors affecting the comorbidity of these disorders is to use genetic animal models, such as mouse lines selectively bred for voluntary ethanol consumption. We hypothesized that mice from lines that were bred for high-alcohol preference would manifest increased depression-like phenotypes compared to low-alcohol preferring mice. Mice that were bi-directionally selected and bred on the basis of their High-(HAP) or Low-Alcohol Preference (LAP) were tested in the open-field (OFT), dark-light box (DLB), forced swim (FST), and learned helplessness tests (LH). The study was conducted in two independently derived replicates. In the OFT, both HAP2 and HAP3 mice showed higher levels of general locomotion compared to LAP mice. However, only HAP2 mice spent more time in the center compared to LAP2 mice. In the DLB, there was a slightly higher anxiety-like phenotype in HAP mice. In both FST and LH, we observed higher depression-like behaviors in HAP mice compared to LAP mice, but this was limited to the Replicate 2 mice. Overall, we identified affect-related behavioral changes in mouse lines bred for high-alcohol preference. Notably, the Replicate 3 lines that showed fewer depression-like behaviors also manifest smaller differences in alcohol intake. These data suggest that there may be overlap between genes that predispose to excessive alcohol intake and those underlying affective-related behaviors in the mouse. PMID:21989731

We hypothesized that mice from lines that were bred for high-alcohol preference would manifest increased depression-like phenotypes compared to low-alcohol preferring mice. Mice that were bi-directionally selected and bred on the basis of their High- (HAP) or Low-Alcohol Preference (LAP) were tested in the open-field (OFT), dark-light box (DLB), forced swim (FST), and learned helplessness tests (LH). The study was conducted in two independently derived replicates. In the OFT, both HAP2 and HAP3 mice showed higher levels of general locomotion compared to LAP mice. However, only HAP2 mice spent more time in the center compared to LAP2 mice. In the DLB, there was a slightly higher anxiety-like phenotype in HAP mice. In both FST and LH, we observed higher depression-like behaviors in HAP mice compared to LAP mice, but this was limited to the Replicate 2 mice. Overall, we identified affect-related behavioral changes in mouse lines bred for high-alcohol preference. Notably, the Replicate 3 lines that showed fewer depression-like behaviors also manifest smaller differences in alcohol intake. These data suggest that there may be overlap between genes that predispose to excessive alcohol intake and those underlying affect-related behaviors in the mouse.

Reports of beneficial effects of exercise on psychological health in humans are increasingly supported by basic research studies. Exercise is hypothesized to regulate antidepressant-related mechanisms and we therefore characterized the effects of chronic exercise in mouse behavioral paradigms relevant to antidepressant actions. Mice given free access to running wheels showed antidepressant-like behavior in learned helplessness, forced-swim (FST) and tail suspension paradigms. These responses were similar to responses of antidepressant drug-treated animals. When tested under conditions where locomotor activity was not altered, exercising mice also showed reduced anxiety compared to sedentary control mice. In situ hybridization analysis showed that BDNF mRNA was increased in specific subfields of hippocampus after wheel running. We chose one paradigm, the FST, in which to investigate a functional role for brain-derived neurotrophic factor (BDNF) in the behavioral response to exercise. We tested mice heterozygous for a deletion of the BDNF gene in the FST after wheel-running. Exercising wild-type mice showed the expected antidepressant-like behavioral response in the FST but exercise was ineffective in improving FST performance in heterozygous BDNF knockout mice. A possible functional contribution of a BDNF signaling pathway to FST performance in exercising mice was investigated using the specific MEK inhibitor PD184161 to block the MAPK signaling pathway. Subchronic administration of PD184161 to exercising mice blocked the antidepressant-like behavioral response seen in vehicle-treated exercising mice in the FST. In summary, chronic wheel-running exercise in mice results in antidepressant-like behavioral changes that may involve a BDNF related mechanism similar to that hypothesized for antidepressant drug treatment.

Attributional Style and Depression in Multiple Sclerosis

Several etiologic theories have been proposed to explain depression in the general population. Studying these models and modifying them for use in the multiple sclerosis (MS) population may allow us to better understand depression in MS. According to the reformulated learned helplessness (LH) theory, individuals who attribute negative events to internal, stable, and global causes are more vulnerable to depression. This study differentiated attributional style that was or was not related to MS in 52 patients with MS to test the LH theory in this population and to determine possible differences between illness-related and non-illness-related attributions. Patients were administered measures of attributional style, daily stressors, disability, and depressive symptoms. Participants were more likely to list non-MS-related than MS-related causes of negative events on the Attributional Style Questionnaire (ASQ), and more-disabled participants listed significantly more MS-related causes than did less-disabled individuals. Non-MS-related attributional style correlated with stress and depressive symptoms, but MS-related attributional style did not correlate with disability or depressive symptoms. Stress mediated the effect of non-MS-related attributional style on depressive symptoms. These results suggest that, although attributional style appears to be an important construct in MS, it does not seem to be related directly to depressive symptoms; rather, it is related to more perceived stress, which in turn is related to increased depressive symptoms.

A cry unheard: sudden reductions in blood pressure while talking about feelings of hopelessness and helplessness.

PubMed

Lynch, J J; Lynch, K E; Friedmann, E

1992-01-01

This paper describes sudden extreme drops in blood pressure in both experimental and clinical situations when a person is talking about or describing situations of hopelessness and helplessness. These changes are discussed in the context of historical perspectives about the cardiovascular system. A new perspective is introduced, one in which these blood pressure changes are seen as part of an unheard cry for understanding. It is hypothesized that such changes do not occur in response to a person's attempts to communicate a sense of hopelessness, but rather are the biological foundations of the hopelessness itself. Viewed from such a context an entirely new therapeutic approach is outlined regarding the treatment of patients suffering from a wide variety of psychosomatic as well as psychological disturbances.

Do patients at risk for psychological maladjustment during fertility treatment present lower intentions to comply with recommended treatment than patients not at risk? Patients at risk of psychological maladjustment present similar high intentions to comply with recommended fertility treatment to those not at risk but their intentions are conditioned by the degree of control they perceive over their fertility and its treatment and their capacity to accept a future without biological children. Infertile couples refer to the psychological burden of treatment as one of the most important reasons for withdrawal from recommended treatment. The SCREENIVF can be used before treatment to screen patients at risk for psychological maladjustment by assessing five risk factors: anxiety, depression, helplessness and lack of acceptance cognitions and social support. Cross-sectional study. First, we investigated the psychometric properties of the Portuguese version of the SCREENIVF. Secondly, we investigated associations between risk for psychological maladjustment and intentions to comply with treatment. Two hundred and ninety-one women and 92 men undergoing any stage of fertility treatment at Portuguese infertility clinics were recruited online or in the clinical setting (55% response rate). Participants completed questionnaires that assessed their emotional adjustment, quality of life and compliance intentions. The confirmatory factor analysis for the SCREENIVF indicated good fit [χ(2) = 188.50, P < 0.001; comparative fit index = 0.97; root-mean-square error of approximation = 0.06 (90% CI 0.05-0.07)] and all dimensions were reliable (α ≥ 0.70, except depression for men: α = 0.66). Fifty-two percent of women and 30% of men were at risk for maladjustment. Women and men at risk and not at risk for maladjustment reported similar intentions to comply with treatment (P > 0.05). Cognitive risk factors moderated negative associations found between distress and compliance intentions. Higher anxiety was associated with lower compliance intentions for patients with lower helplessness cognitions (β = -0.45, P = 0.01) and men with higher acceptance cognitions (β = -0.60; P = 0.03), but not for patients with higher helplessness cognitions (β = 0.25, P = 0.13) and men with lower acceptance cognitions (β = 0.38; P = 0.21). Higher depression was associated with lower compliance intentions for patients with higher helplessness cognitions (β = -0.33, P = 0.02), but not for patients with lower helplessness cognitions (β = 0.19, P = 0.30). Few men participated and thus only medium-to-large effect sizes could be detected for them. Forty-eight percent of participants were recruited online and this could have resulted in higher rates of patients at risk. The SCREENIVF is not useful to identify patients at risk for non-compliance. However, the clinic staff should be aware that patients who score high on helplessness cognitions and low on acceptance may need additional decisional aid to make autonomous and satisfying decisions about uptake of treatment. The Portuguese version of the SCREENIVF is valid and reliable and can be used with women undergoing any type of fertility treatment.

Recent empirical studies revealed that fostering patients' perception of meaning in their life is an essential task for palliative care clinicians. However, few studies have reported the effects of training programs for nurses specifically aimed at improving skills to relieve the meaninglessness of terminally ill cancer patients, and we have had no specific measurement instruments. The primary aims of this study were 1) to validate measurement tools to quantify nurses' self-reported practice and attitudes toward caring for terminally ill cancer patients feeling meaninglessness and 2) to explore the effects of the five-hour educational workshop focusing on meaninglessness on nurses' self-reported practice, attitudes toward caring for such patients, confidence, burnout, death anxiety, and meaning of life. A quasi-experimental pre-post questionnaire survey was performed on 147 nurses. The questionnaire was distributed before the intervention workshop and one and six months after. The workshop consisted of lecture, role-play, and the exercise of assessment and care planning based on two vignette verbatim records. First, using the first questionnaire sample and an additional sample of 20 nurses for the test-retest examination, we validated a six-item Self-Reported Practice scale, and an eight-item Attitudes Toward Caring for Patients Feeling Meaninglessness scale with three subscales (Willingness to Help, Positive Appraisal, and Helplessness). The nurses also completed a scale to assess confidence in caring for terminally ill patients with meaninglessness, the Maslach Burnout Inventory, the Death Attitude Inventory, the Frommelt Attitudes Toward Care of the Dying scale, the Self-Reported Practice Score in General Communication, and the three pain-related items from the Palliative Care Quiz for Nursing. For the Self-Reported Practice scale and the subscales of the Attitudes Toward Caring for Patients Feeling Meaninglessness scale, the Cronbach's alpha coefficients were 0.63-0.91, and the intra-class correlations were 0.89-0.94. The Self-Reported Practice scale significantly, but moderately, correlated with the Self-Reported Practice Score in General Communication (P=0.41). The Willingness to Help and Helplessness subscales significantly but weakly correlated with the Frommelt scale (P=-0.27, 0.21). Both scales did not correlate or minimally correlated with the Palliative Care Quiz for Nursing (P<0.20). The construct validity was confirmed using factor analysis. At the follow-up, of 147 nurses who participated in this workshop, 91 (62%) and 80 (54%) nurses responded. Self-reported practice and confidence significantly improved, whereas helplessness, emotional exhaustion, and death anxiety significantly decreased. The percentages of nurses who evaluated this program as "useful" or "very useful" were 79% (to understand the conceptual framework in caring for terminally ill patients with meaninglessness), 73% (to help in self-disclosing nurses' personal beliefs, values, and life goals), and 80% (to help in learning how to provide care for patients with meaninglessness). The Self-Reported Practice scale and the Attitudes Toward Caring for Patients Feeling Meaninglessness scale are reliable and valid tools to specifically quantify nurses' self-reported practice and attitudes toward caring for terminally ill cancer patients feeling meaninglessness of life. The five-hour workshop appeared to have a modest but significant beneficial effect on nurse-reported practice, attitudes, and confidence in providing care for terminally ill cancer patients feeling meaninglessness. Further educational intervention trials with control groups are promising.

To evaluate coping strategies of Asian RA patients and their associations with health-related quality of life (HRQoL). A cross-sectional sample of patients with established RA was evaluated using measures of coping (Coping in Rheumatoid Arthritis Questionnaire [C-RAQ]; appraisal of coping effectiveness and helplessness), HRQoL (Mental and Physical Components [MCS/PCS] of the Short Form 12v2; Rheumatoid Arthritis Impact of Disease score [RAID]) and clinical/laboratory assessments. Principal component analysis was conducted to identify coping strategies. Multiple linear regression analyses were performed to evaluate the associations between coping strategies and HRQoL outcomes. The study sample comprised 101 patients, 81% female, 72.3% Chinese, mean age 54.2 ± 12.6 years. Five coping strategies were identified: Active problem solving (E = 5.36), Distancing (E = 2.30), Concealment (E = 1.89), Cognitive reframing (E = 1.55) and Emotional expression (E = 1.26). Concealment was consistently associated with PCS (r s = -0.23, P = 0.049), MCS (r s = -0.24, P = 0.04) and RAID (r s = 0.39, P < 0.001), and was significant in the multivariate model to explain lower disease-specific HRQoL (RAID) even after adjusting for disease activity, coping effectiveness and helplessness (β = 0.20, P = 0.04). Emotional expression was associated with poorer physical HRQoL (PCS), after adjusting for disease severity, body mass index, coping effectiveness, helplessness and Concealment (β = -0.39, P < 0.001). Perceived coping-related helplessness was significant in multivariate correlates for PCS (β = -0.25, P = 0.036), MCS (β = -0.29, P = 0.02) and RAID (β = 0.53, P < 0.001), after adjusting for covariates. Concealment and Emotional expression are associated with lower disease-specific HRQoL and physical HRQoL respectively, with the former coping strategy likely to be culture-specific. Interventions should tailor psychosocial support needs to address not only coping strategies, but patients' perception of their coping. © 2016 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.
'You feel helpless, that's exactly it': parents' and young people's control beliefs about bed-wetting and the implications for practice.

'You feel helpless, that's exactly it': parents' and young people's control beliefs about bed-wetting and the implications for practice Young people wet the bed when they fail to wake up to a full bladder. The causes of bed-wetting are far from certain and this uncertainty is reflected in the diversity of treatments on offer and the lack of any guarantee that treatment will work in a particular case. Most young people are sad and ashamed about the bed-wetting and want it to stop, but they vary widely in their belief in their own capacity to influence the situation, and in their optimism about what the future holds. The problem can persist into adolescence or even adulthood, with far reaching social and emotional consequences, both for the young people and their families. In an ethnographic study involving 19 families 'perceived helplessness' emerged as a key issue permeating the whole system and often activating a downward spiral, leading to abdication of effort and responsibility by the young people themselves, by their parents and sometimes by health care professionals. Informed by the insights gained from this study and an extensive review of the literature on perceived control the Family Perspectives on Bed Wetting Questionnaire has been developed to explore family members' feelings, degree of concern and dimensions of perceived control relating to: effort, ability, luck, important others and the unknown. This questionnaire was used as a basis for structured interviews with family members in a longitudinal survey, involving 40 families attending one of nine community-based, nurse-led enuresis clinics in Greater Glasgow. It was found that only 38% of the young people were entering into treatment with the belief that they had the ability to be dry at night. This became self-fulfilling, with only 33% achieving initial success of 14 consecutive dry nights in a 16-week period (chi-squared test, P=0.029). Seventy per cent of young people felt that luck was important, while most parents felt that luck had little part to play. Implications for practice include the need to assess the families' readiness to engage in treatment, to create opportunities for effective control and to encourage realistic expectations.

Interleukin-1 may link helplessness-hopelessness with cancer progression: a proposed model.

PubMed

Argaman, Miriam; Gidron, Yori; Ariad, Shmuel

2005-01-01

A model of the relations between psychological factors and cancer progression should include brain and systemic components and their link with critical cellular stages in cancer progression. We present a psychoneuroimmunological (PNI) model that links helplessness-hopelessness (HH) with cancer progression via interleukin-1beta (IL-1beta). IL-1beta was elevated in the brain following exposure to inescapable shock, and HH was minimized by antagonizing cerebral IL-1beta. Elevated cerebral IL-1beta increased cancer metastasis in animals. Inescapable shock was associated with systemic elevations of IL-1beta and peripheral IL-1beta was associated with escape from apoptosis, angiogenesis, and metastasis. Involvement of the sympathetic nervous system and the hypothalamic-pituitary-adrenal axis are discussed. Future studies need to identify the role of additional factors in this PNI pathway.

Illness cognitions are important mediators between disease and psychological adjustment. Evidence related to illness cognitions among patients with breast cancer remains limited. The purpose of this study was to examine illness cognitions among Chinese women with breast cancer and associations with socio-demographic and clinical factors. A cross-sectional study was carried out involving 313 women with breast cancer recruited from a general hospital and a social cancer support club in Beijing from October 2016 to May 2017. Data were collected using the Illness Cognition Questionnaire. Participants reported positive overall cognition regarding breast cancer (helplessness, 13.70 ± 4.24; acceptance, 16.86 ± 4.30; perceived benefits, 17.93 ± 3.86). A multiple regression model indicated that six factors were associated with illness cognitions: treatment phase of disease, having no children, not returning to work (positive associations with helplessness, negative associations with acceptance; age (negative associations with helplessness, positive associations with acceptance); treatment phase of disease, having no medical insurance (negative associations with perceived benefit); and disease duration (positive associations with acceptance). This study reports on the presence of different illness cognitions in Chinese women with breast cancer and the associated factors, and the results could help oncology medical and nursing staff identify risk factors for poor emotional adjustment to breast cancer and the patients who may benefit from interventions aimed at improving the presence of positive illness cognitions.

The hopelessness theory of depression: attributional aspects.

Alloy, L B; Abramson, L Y; Metalsky, G I; Hartlage, S

1988-02-01

In this article, we clarify, expand and revise the basic postulates of the hopelessness theory of depression (Abramson, Alloy & Metalsky, 1988a; Abramson, Metalsky & Alloy, 1987, 1988b; previously referred to as the reformulated helplessness theory of depression: Abramson, Seligman & Teasdale, 1978) and place the theory more explicitly in the context of work in descriptive psychiatry about the heterogeneity among the depressive disorders. We suggest that the hopelessness theory hypothesizes the existence in nature of an, as yet, unidentified subtype of depression--'hopelessness depression'--defined, in part, by its cause. We then give a critique of work conducted to test the hopelessness theory and explicate the limitations in research strategy associated with this line of work. Our critique includes a logical analysis that deduces the conceptual and methodological inadequacies of the research strategies used to test the theory. Finally, we suggest more adequate research strategies for testing the hopelessness theory and discuss conceptual and assessment issues that will arise in conducting such tests with special emphasis on attributional styles.

Background Recent genome-wide association studies have associated polymorphisms in the gene CACNA1C, which codes for Cav1.2, with a bipolar disorder and depression diagnosis. Methods The behaviors of wild type and Cacna1c heterozygous mice of both sexes were evaluated in a number of tests. Based upon sex differences in our mouse data, we assessed a gene x sex interaction for diagnosis of mood disorders in human subjects. Data from the NIMH-BP Consortium and the GenRED Consortium were examined utilizing a combined dataset that included 2,021 mood disorder cases (1,223 females) and 1,840 controls (837 females). Results In both male and female mice, Cacna1c haploinsufficiency is associated with lower exploratory behavior, decreased response to amphetamine, and antidepressant-like behavior in the forced swim and tail suspension tests. Female, but not male, heterozygous mice displayed decreased risk-taking behavior or increased anxiety in multiple tests, greater attenuation of amphetamine-induced hyperlocomotion, decreased development of learned helplessness, and a decreased acoustic startle response indicating a sex-specific role of Cacna1c. In humans, sex-specific genetic association was seen for two intronic single nucleotide polymorphisms (SNPs), rs2370419 and rs2470411, in CACNA1C, with effects in females (OR=1.64, 1.32), but not in males (OR=0.82, 0.86). The interactions by sex were significant after correction for testing 190 SNPs (P=1.4 x 10−4, 2.1 x 10−4; Pcorrected=0.03, 0.04), and were consistent across two large data sets. Conclusions Our preclinical results support a role for CACNA1C in mood disorder pathophysiology, and the combination of human genetic and preclinical data support an interaction between sex and genotype.

R-ketamine: a rapid-onset and sustained antidepressant without psychotomimetic side effects

Although the efficacy of racemate ketamine, a rapid onset and sustained antidepressant, for patients with treatment-resistant depression was a serendipitous finding, clinical use of ketamine is limited, due to psychotomimetic side effects and abuse liability. Behavioral and side-effect evaluation tests were applied to compare the two stereoisomers of ketamine. To elucidate their potential therapeutic mechanisms, we examined the effects of these stereoisomers on brain-derived neurotrophic factor (BDNF)–TrkB signaling, and synaptogenesis in selected brain regions. In the social defeat stress and learned helplessness models of depression, R-ketamine showed a greater potency and longer-lasting antidepressant effect than S-ketamine (esketamine). Furthermore, R-ketamine induced a more potent beneficial effect on decreased dendritic spine density, BDNF–TrkB signaling and synaptogenesis in the prefrontal cortex (PFC), CA3 and dentate gyrus (DG) of the hippocampus from depressed mice compared with S-ketamine. However, neither stereoisomer affected these alterations in the nucleus accumbens of depressed mice. In behavioral tests for side effects, S-ketamine, but not R-ketamine, precipitated behavioral abnormalities, such as hyperlocomotion, prepulse inhibition deficits and rewarding effects. In addition, a single dose of S-ketamine, but not R-ketamine, caused a loss of parvalbumin (PV)-positive cells in the prelimbic region of the medial PFC and DG. These findings suggest that, unlike S-ketamine, R-ketamine can elicit a sustained antidepressant effect, mediated by increased BDNF–TrkB signaling and synaptogenesis in the PFC, DG and CA3. R-ketamine appears to be a potent, long-lasting and safe antidepressant, relative to S-ketamine, as R-ketamine appears to be free of psychotomimetic side effects and abuse liability. PMID:26327690
GLYX-13, a NMDA Receptor Glycine-Site Functional Partial Agonist, Induces Antidepressant-Like Effects Without Ketamine-Like Side Effects

Recent human clinical studies with the NMDA receptor (NMDAR) antagonist ketamine have revealed profound and long-lasting antidepressant effects with rapid onset in several clinical trials, but antidepressant effects were preceded by dissociative side effects. Here we show that GLYX-13, a novel NMDAR glycine-site functional partial agonist, produces an antidepressant-like effect in the Porsolt, novelty induced hypophagia, and learned helplessness tests in rats without exhibiting substance abuse-related, gating, and sedative side effects of ketamine in the drug discrimination, conditioned place preference, pre-pulse inhibition and open-field tests. Like ketamine, the GLYX-13-induced antidepressant-like effects required AMPA/kainate receptor activation, as evidenced by the ability of NBQX to abolish the antidepressant-like effect. Both GLYX-13 and ketamine persistently (24 h) enhanced the induction of long-term potentiation of synaptic transmission and the magnitude of NMDAR-NR2B conductance at rat Schaffer collateral-CA1 synapses in vitro. Cell surface biotinylation studies showed that both GLYX-13 and ketamine led to increases in both NR2B and GluR1 protein levels, as measured by Western analysis, whereas no changes were seen in mRNA expression (microarray and qRT-PCR). GLYX-13, unlike ketamine, produced its antidepressant-like effect when injected directly into the medial prefrontal cortex (MPFC). These results suggest that GLYX-13 produces an antidepressant-like effect without the side effects seen with ketamine at least in part by directly modulating NR2B-containing NMDARs in the MPFC. Furthermore, the enhancement of ‘metaplasticity' by both GLYX-13 and ketamine may help explain the long-lasting antidepressant effects of these NMDAR modulators. GLYX-13 is currently in a Phase II clinical development program for treatment-resistant depression. PMID:23303054
