Cerebral palsy (CP) is the most common significant motor impairment in childhood. CP is defined as a primary disorder of posture and movement; however, intellectual impairment is prevalent in children with CP. The purpose of this study was to examine the intelligence level associated with gross motor function and hand function, type of CP, the presence of comorbid disorders such as epilepsy, and other factors. In total, 107 children with CP were included. Age, gender, prenatal/natal/postnatal risk factors, type of CP, and presence of other neurodevelopmental disorders were recorded as demographic findings. Intellectual functions of the patients were determined by clinical assessment, adaptive function of daily life, and individualized, standardized intelligence testing. The gross motor function and hand function of the patients were classified using the "Gross Motor Function Classification System" and "Bimanual Fine Motor Function" measurements, respectively. The mean age of the patients was 8.10±3.43 years (2-16 years). The study included 63 (58.9%) male patients and 44 (41.1%) female patients. During clinical typing, 80.4% of the patients were spastic, 11.2% were mixed, 4.7% were dyskinetic, and 3.7% were ataxic. Intellectual functioning tests found 26.2% of the children within the intellectual norm and that 10% of the children had a borderline intellectual disability, 16% of them had a mild intellectual disability, 17% of them had a moderate intellectual disability, and 30.8% of them had a severe intellectual disability. No significant relationship was determined between the CP type and intellectual functioning (p>0.05). Intellectual functioning was found to be significantly correlated with hand functions and motor levels (p<0.001). Factors related with intellectual functioning were neonatal convulsion, epilepsy, and speech disorders. Intelligence assessment should be an essential part of CP evaluation and research. There is not enough reliable knowledge, unanimity regarding validity data, and population-specific norms in the intelligence assessments of children with CP. Research is required to assess properly intelligence for children with CP.

Kcnt1 encoded sodium-activated potassium channels (Slack channels) are highly expressed throughout the brain where they modulate the firing patterns and general excitability of many types of neurons. Increasing evidence suggests that Slack channels may be important for higher brain functions such as cognition and normal intellectual development. In particular, recent findings have shown that human Slack mutations produce very severe intellectual disability and that Slack channels interact directly with the Fragile X mental retardation protein (FMRP), a protein that when missing or mutated results in Fragile X syndrome (FXS), the most common form of inherited intellectual disability and autism in humans. We have now analyzed a recently developed Kcnt1 null mouse model in several behavioral tasks to assess which aspects of memory and learning are dependent on Slack. We demonstrate that Slack deficiency results in mildly altered general locomotor activity, but normal working memory, reference memory, as well as cerebellar control of motor functions. In contrast, we find that Slack channels are required for cognitive flexibility, including reversal learning processes and the ability to adapt quickly to unfamiliar situations and environments. Our data reveal that hippocampal-dependent spatial learning capabilities require the proper function of Slack channels. © 2015 Bausch et al.; Published by Cold Spring Harbor Laboratory Press.

Synaptic dysfunction and intellectual disability.

PubMed

Valnegri, Pamela; Sala, Carlo; Passafaro, Maria

2012-01-01

Intellectual disability (ID) is a common and highly heterogeneous paediatric disorder with a very severe social impact. Intellectual disability can be caused by environmental and/or genetic factors. Although in the last two decades a number of genes have been discovered whose mutations cause mental retardation, we are still far from identifying the impact of these mutations on brain functions. Many of the genes mutated in ID code for several proteins with a variety of functions: chromatin remodelling, pre-/post-synaptic activity, and intracellular trafficking. The prevailing hypothesis suggests that the ID phenotype could emerge from abnormal cellular processing leading to pre- and/or post-synaptic dysfunction. In this chapter, we focus on the role of small GTPases and adhesion molecules, and we discuss the mechanisms through which they lead to synaptic network dysfunction.

Background Leisure activity participation has been shown to lower risks of cognitive decline in non-stroke populations. However, effects of leisure activities participation upon cognitive functions and risk of dementia after stroke are unclear. The purpose of this study is to examine the effects of recent past leisure activities participation upon cognitive functions and risk of incident dementia after stroke. Methods Hospital-based, retrospective cohort study. 88 of 1,013 patients with stroke or TIA having no prestroke dementia were diagnosed to have incident poststroke dementia (PSD) 3–6 months after stroke. Regular participation (≥3 times per week) in intellectual, recreational, social and physical activities over the year before the index stroke was retrospectively recorded at 3–6 months after stroke. Results Logistic regression analyses showed that regular participation in intellectual (RR 0.36, 95%CI 0.20–0.63) and stretching & toning physical exercise (0.37, 0.21–0.64) was significantly associated with a reduced risk of PSD after controlling for age, education, prestroke cognitive decline, stroke subtype, prior strokes and chronic brain changes including white matter changes, old infarcts and global atrophy. Results were similar in patients with past strokes in unadjusted models. Participation in increased number of activities in general (r = 0.41, p<0.01) and in intellectual (r = 0.40, p<0.01), recreational (r = 0.24, p<0.01), strenuous aerobic (r = 0.23, p<0.01) and mind-body (r = 0.10, p<0.01) activities was associated with higher poststroke Mini-mental State Examination scores in models adjusted for prestroke cognitive decline. Conclusions Regular participation in intellectual activities and stretching & toning exercise was associated with a significantly reduced short-term risk of PSD in patients with and without recurrent strokes. Participation in greater number of recent past leisure activities was associated with better poststroke cognitive performance. Findings of this retrospective cohort study call for studies of activity intervention for prevention of cognitive decline in individuals at elevated risk of stroke. PMID:27454124

The present study examined the moderating effects of intellectual functioning and ASD symptom severity on the relation between age and adaptive functioning in 220 youth with autism spectrum disorder (ASD). Regression analysis indicated that intellectual functioning and ASD symptom severity moderated the relation between age and adaptive functioning. For younger children with lower intellectual functioning, higher ASD symptom severity was associated with better adaptive functioning than that of those with lower ASD symptom severity. Similarly, for older children with higher intellectual functioning, higher ASD symptom severity was associated with better adaptive functioning than that of those with lower ASD symptom severity. Analyses by subscales suggest that this pattern is driven by the Conceptual subscale. Clinical and research implications are discussed.

The purpose of this review was to describe literature relating to transition for young people with an intellectual disability and identify gaps within the current knowledge base. A narrative literature review was undertaken. Searches of databases Medline, CINAHL, PsycINFO, ERIC, ISI Web of Science and ProQuest 500 International provided relevant research articles. The search terms used were intellectual disability, transition, employment, and ICF as well as other terms derived from the ICF. Manual searches of reference lists identified additional studies. Furthermore, government websites were searched for relevant reports and policies. Transition literature was explored by ICF domains; body functions and structures, activity and participation and contextual factors. Studies were identified in some but not all areas and included literature describing self-determination and participation in leisure activities for those with mild intellectual disability. However, significant gaps were found particularly for those with severe intellectual disability. The ICF is a useful tool in framing a review of transition literature for young people with intellectual disability due to the complexity and multi-faceted nature of transition. The important influence of environmental factors including family systems, post-school services and access to transport were highlighted as having considerable impacts on transition outcomes.

Development and evaluation of a structured programme for promoting physical activity among seniors with intellectual disabilities: a study protocol for a cluster randomized trial

PubMed Central

2013-01-01

Background Older people with intellectual disabilities have very low physical activity levels. Well designed, theory-driven and evidence-based health promotion programmes for the target population are lacking. This paper describes the design of a cluster-randomised trial for a systematically developed health promotion programme aimed at improving physical activity and increasing fitness among seniors with intellectual disabilities. Methods and design The Intervention Mapping protocol was used for programme development. After defining the programme’s objectives, the following behavioural techniques were selected to achieve them: Tailoring, Education, Modelling, Mirroring, Feedback, Reinforcement and Grading. With professionals and managers of provider services for people with intellectual disabilities, we translated these strategies into a structured day-activity programme, that consisted of a physical activity and an education programme. The programme will be executed in five day-activity centres in groups of eight to ten seniors during eight months, whereas seniors in five other centres receive care as usual. The physical activity level, as measured in number of steps a day, will be used as primary outcome measurement. Secondary outcome measurements include motor fitness, cardio respiratory fitness, morphological and metabolic fitness, ADL, functional deterioration and depressive symptoms. Differences in the primary and secondary outcome measures between participants and controls will be analysed using generalized estimation equations, correcting for day-activity center as cluster. Discussion This paper provides insight into the development and content of a theory-driven intervention aimed at behavioural change in a population with a low intellectual level. Its evaluation design is described. The programme’s applicability to other populations is discussed. Trial registration Trial number: ISRCTN82341588 PMID:23938154

2017-01-01

Impaired intellectual functioning is an important risk factor for the emergence of severe mental illness. Unlike many other forms of mental disorder however, the association between bipolar disorder and intellectual deficits is unclear. In this narrative review, we examine the current evidence on intellectual functioning in children and adolescents at risk for developing bipolar disorder. The results are based on 18 independent, peer-reviewed publications from 1980 to 2017 that met criteria for this study. The findings yielded no consistent evidence of lower or higher intellectual quotient (IQ) in offspring of parents diagnosed with bipolar disorder. Some tentative evidence was found for lower performance IQ in offspring of bipolar parents as compared to controls. It is recommended that future research examine variability in intellectual functioning and potential moderators. These findings demonstrate the need to examine how intellectual functioning unfolds across development given the potential role of IQ as a marker of vulnerability or resilience in youth at high risk for affective disorders.

Background Studies on autism have tended to focus either on those with intellectual disability (ie, those with intellectual quotient [IQ] under 70) or on the group that is referred to as “high-functioning”, that is, those with borderline, average or above average IQ. The literature on cognition and daily functioning in autism spectrum disorder combined specifically with borderline intellectual functioning (IQ 70–84) is limited. Methods From a representative group of 208 preschool children diagnosed with autism spectrum disorder, those 50 children in the group with borderline intellectual functioning at ages 4.5–6.5 years were targeted for follow-up at a median age of 10 years. A new cognitive test was carried out in 30 children. Parents were interviewed with a semi-structured interview together with the Vineland Adaptive Behavior Scales (n=41) and the Autism-Tics, attention-deficit/hyperactivity disorder (AD/HD) and other comorbidities inventory (A-TAC) (n=36). Results Most children of interviewed parents presented problems within several developmental areas. According to A-TAC and the clinical interview, there were high rates of attention deficits and difficulties with regulating activity level and impulsivity. Vineland Adaptive Behavior Scales composite scores showed that at school age, a majority of the children had declined since the previous assessment at ages between 4.5 and 6.5 years. Almost half the tested group had shifted in their IQ level, to below 70 or above 84. Conclusion None of the children assessed was without developmental/neuropsychiatric problems at school-age follow-up. The results support the need for comprehensive follow-up of educational, medical and developmental/neuropsychiatric needs, including a retesting of cognitive functions. There is also a need for continuing parent/family follow-up and support. PMID:29042781

Objectives Low cognitive ability is associated with subsequent functional disability. Whether this association extends across adult life has been little studied. The aim of this study was to examine the association between intellectual ability in young adulthood and physical functioning during a 10-year follow-up in older age. Methods 360 persons of the Helsinki Birth Cohort Study (HBCS) male members, born between 1934- 1944 and residing in Finland in 1971, took part in The Finnish Defence Forces Basic Intellectual Ability Test during the first two weeks of their military service training between 1952- 72. Their physical functioning was assessed twice using the Short Form 36 (SF-36) questionnaire at average ages of 61 and 71 years. A longitudinal path model linking Intellectual Ability Test score to the physical functioning assessments was used to explore the effect of intellectual ability in young adulthood on physical functioning in older age. Results After adjustments for age at measurement, childhood socioeconomic status and adult BMI (kg/m2), better intellectual ability total and arithmetic and verbal reasoning subtest scores in young adulthood predicted better physical functioning at age 61 years (P-values < 0.021). Intellectual ability total and arithmetic and verbal reasoning subtest scores in young adulthood had indirect effects on physical functioning at age 71 years (P-values < 0.022) through better physical functioning at age 61 years. Adjustment for main chronic diseases did not change the results materially. Conclusion Better early life intellectual ability helps in maintaining better physical functioning in older age.

Objective: In the Netherlands, patients with borderline intellectual functioning are eligible for specialized mental health care. This offers the unique possibility to examine the mix of psychiatric disorders in patients who, in other countries, are treated in regular outpatient mental health care clinics. Our study sought to examine the rates of all main Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision, Axis I psychiatric diagnoses in outpatients with borderline intellectual functioning of 2 specialized regional psychiatric outpatient departments and to compare these with rates of the same disorders in outpatients from regular mental health care (RMHC) and outpatients with mild intellectual disabilities (IDs). Method: Our study was a cross-sectional, anonymized medical chart review. All participants were patients from the Dutch regional mental health care provider Rivierduinen. Diagnoses of patients with borderline intellectual functioning (borderline intellectual functioning group; n = 235) were compared with diagnoses of patients from RMHC (RMHC group; n = 1026) and patients with mild ID (mild ID group; n = 152). Results: Compared with the RMHC group, psychotic and major depressive disorders were less common in the borderline intellectual functioning group, while posttraumatic stress disorder and V codes were more common. Compared with the mild ID group, psychotic disorders were significantly less common. Conclusion: Mental health problems in people with borderline intellectual functioning may not be well addressed in general psychiatry, or by standard psychiatry for patients with ID. Specific attention to this group in clinical practice and research may be warranted lest they fall between 2 stools. PMID:25007114

2008-03-01

Typical Intellectual Engagement (TIE) comprises the preference to engage in cognitively demanding activities and has been proposed as a potential explanatory variable of individual differences in cognitive abilities. Little is known, however, about the factorial structure of TIE, its relations to socio-demographic variables, and its influence on intellectual functioning in old age. In the present study, data of 364 adults (65-81 years) from the Zurich Longitudinal Study on Cognitive Aging (ZULU) were used to investigate the factorial structure of TIE and to examine the hypothesis that TIE is associated more strongly with crystallized intelligence than with fluid intelligence in old age. A measurement model of a second order factor based on a structure of four correlated first order factors (Reading, Problem Solving, Abstract Thinking, and Intellectual Curiosity) evinced an excellent fit. After controlling for age, sex, and formal education, TIE was more strongly associated with crystallized intelligence than with fluid intelligence, comparable to results in younger persons. More detailed analyses showed that this association is mostly defined via Reading and Intellectual Curiosity.

2009-01-01

This study aimed to characterise the neuropsychological functioning of adults with comorbid attention deficit hyperactivity disorder (ADHD) and intellectual disability. Individuals with ADHD and mild-borderline range intelligence (N=59) and individuals with ADHD and normal intellectual functioning (N=95) were compared on attentional and response inhibition tasks. The comorbid group had significantly lower scores on the majority of measures in comparison with the ADHD alone group. These differences remained significant after co-varying for level of intellectual functioning for variables measuring selective attention and errors of commission during sustained attention. This suggests that individuals with comorbid ADHD and intellectual disability may be vulnerable to a 'double deficit' from both disorders in certain aspects of cognitive functioning.

Cognitive decline in aging can negatively impact quality of life in the elderly. However, studies have shown that elderly engaged in advanced activities of daily living (AADLs) can maintain or enhance global cognitive function or specific domains. Objective To investigate the relationship between engagement in AADLs and domains of cognition in elderly from seven different locations in Brazil. Methods A cross-sectional study involving 2,549 elderly without cognitive deficits suggestive of dementia was conducted. Data were collected on sociodemographic characteristics, health status, the Mini-Mental State Exam (MMSE) by subdomain (orientation, memory, attention/calculus, language and constructional praxis), and engagement in AADL grouped under physical, social and intellectual activities. Results Multivariate linear regression analysis revealed an association, albeit modest, between intellectual AADLs and the domains orientation, attention/calculus, language and constructional praxis (R2=0.005, 0.008, 0.021, and 0.021 respectively). Social AADLs were correlated with memory (R2=0.002) and language (R2=0.004) domains. No association was found between physical AADLs and MMSE domains. Schooling and family income were the sociodemographic variables exhibiting the strongest relationship with cognitive domains. Conclusion The study found associations between intellectual and social AADLs with higher cognitive performance, suggesting that active aging can provide opportunities to attenuate cognitive decline in aging.

Using whole-exome sequencing, we have identified in ten families 14 individuals with microcephaly, developmental delay, intellectual disability, hypotonia, spasticity, seizures, sensorineural hearing loss, cortical visual impairment, and rare autosomal-recessive predicted pathogenic variants in spermatogenesis-associated protein 5 (SPATA5). SPATA5 encodes a ubiquitously expressed member of the ATPase associated with diverse activities (AAA) protein family and is involved in mitochondrial morphogenesis during early spermatogenesis. It might also play a role in post-translational modification during cell differentiation in neuronal development. Mutations in SPATA5 might affect brain development and function, resulting in microcephaly, developmental delay, and intellectual disability. Copyright © 2015 The American Society of Human Genetics.

Individuals with intellectual disabilities (ID) (50 < IQ < 79) show impaired motor and postural control, these impairments are highly related to falls and injuries. Recent studies demonstrated these impairments are related with fine and gross motor development, which are more strongly associated with cognition, and consequently language for individuals with ID than for without ID. Despite these studies, little is known about the structure and functioning of this population's spinal cord, which is highly involved in postural control. The aim of our study was to assess the latency of the reflex responses in postural muscles after unexpected lateral external perturbations, in individuals with intellectual disabilities compared to typically developed participants. We assessed 16 participants with intellectual disabilities, 9 males and 7 females (aged 24.06 ± 8.66 years) and 20 typical developed participants (CG), 11 females, 9 males, (aged 21.20±1.96 years). While the participants were in an upright standing position electromyography was used to collect data from M. obliquus externus abdominis (OE) muscles, which were activated by unpredictable perturbations applied by a servomotor on a hand-held grip, following the lateral external perturbation to the trunk. The intellectual disabilities group presented contralateral OE muscles latency of 85.71±27.24 ms, and CG group presented 68.62±10.25 ms, no differences was found. Ipsilateral OE muscles latency also did not differs between the groups, ID group showed 96.60±30.20 ms and CG group showed 95.57±33.53 ms. Our study furthers the knowledge about the muscular activity of individuals with intellectual disabilities. The present experimental results may suggest unique spinal cord processing of individuals with intellectual disabilities when they are faced with unexpected lateral external perturbations.

The aim of the present study was to investigate communication function using classification systems and its association with other functional profiles, including gross motor function, manual ability, intellectual functioning, and brain magnetic resonance imaging (MRI) characteristics in children with cerebral palsy (CP). This study recruited 117 individuals with CP aged from 4 to 16 years. The Communication Function Classification System (CFCS), Viking Speech Scale (VSS), Speech Language Profile Groups (SLPG), Gross Motor Function Classification System (GMFCS), Manual Ability Classification System (MACS), and intellectual functioning were assessed in the children along with brain MRI categorization. Very strong relationships were noted among the VSS, CFCS, and SLPG, although these three communication systems provide complementary information, especially for children with mid-range communication impairment. These three communication classification systems were strongly related with the MACS, but moderately related with the GMFCS. Multiple logistic regression analysis indicated that manual ability and intellectual functioning were significantly related with VSS and CFCS function, whereas only intellectual functioning was significantly related with SLPG functioning in children with CP. Communication function in children with a periventricular white matter lesion (PVWL) varied widely. In the cases with a PVWL, poor functioning was more common on the SLPG, compared to the VSS and CFCS. Very strong relationships were noted among three communication classification systems that are closely related with intellectual ability. Compared to gross motor function, manual ability seemed more closely related with communication function in these children. © Copyright: Yonsei University College of Medicine 2018.

Intellectual disability and patient activation may be important drivers of inequities in health service access and health outcomes for people with intellectual disability transitioning from prison to the community. We assessed the association between intellectual disability and patient activation after prison release and examined whether this association varied, depending on whether intellectual disability was identified prior to prison release. Overall, 936 prisoners were screened for intellectual disability by using the Hayes Ability Screening Index and completed the Patient Activation Measure (PAM) within 6 weeks of prison release and again at 1, 3 and 6 months post-release. We estimated the association between intellectual disability status and PAM scores by using a multilevel linear model, adjusting for sociodemographic, behavioural, health and criminogenic factors. We used propensity score matching to estimate the impact of being identified with intellectual disability prior to release from prison on the change in mean PAM score after prison release. Compared with those who screened negative for intellectual disability, ex-prisoners who screened positive, both with and without prior identification of intellectual disability, had significantly decreased mean PAM scores [(B = -4.3; 95% CI: -6.3, -2.4) and (B = -4.5; 95% CI: -6.8, -2.3), respectively] over 6 months of follow-up. Among those who reported being identified with intellectual disability prior to release from prison, a significant increase in PAM score at the 6-month follow-up interview (B = 5.89; 95% CI: 2.35, 9.42; P = 0.001) was attributable to being identified with intellectual disability prior to release. Ex-prisoners screening positive for possible intellectual disability have decreased patient activation for at least 6 months after release from prison. However, individuals whose possible intellectual disability is unidentified appear to be particularly vulnerable. Incarceration is a pivotal opportunity for the identification of intellectual disability and for initiating transitional linkages to health and intellectual disability-specific community services for this marginalised population. © 2017 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

The physical activity level of older adults with intellectual disabilities (ID) is extremely low, and their fitness levels are far beneath accepted norms for older people with normal intelligence and comparable with frail older people. A physical activity programme, including an education programme, was developed for older adults with ID using behaviour change techniques. The programme aimed at improving or maintaining adequate levels of physical activity (primary outcome measure) and motor fitness, cardio respiratory fitness, morphologic and metabolic fitness, activities of daily living, cognitive functioning and depressive symptoms (secondary outcome measures). The programme's efficacy was evaluated in a cluster-randomised clinical trial among people aged 43 years and over with mild-moderate levels of ID. Five day-activity centres were randomised to the participation group. In these centres, 81 older adults participated in groups of 8 to 10 in the programme, three times a week during 8 months. The programme was executed by physical activity instructors and staff of day-activity centres. Five other day-activity centres were randomised to the control group; 70 older adults in these centres received care as usual. The generalised linear model with mixed effects was used to test the programme's effectiveness. Significant effects were found on physical activity, muscle strength, systolic and diastolic blood pressure, serum cholesterol level and cognitive functioning, in favour of the programme's participants. No significant improvements were found on balance, serum glucose, weight, waist circumference, walking speed, mobility, depression or instrumental activities of daily living. The physical activity and fitness programme has established small but significant effects in this sample, but generalising the findings to other settings is difficult due to significant participant dropout. Implementation of evidence-based physical activity programmes among older adults with ID is recommended. Further research is needed to investigate the effectiveness of physical activity on daily life functioning and the development on chronic diseases in the long run. © 2016 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

The ability to perform activities of daily living (ADL) as a component of participation is one of the factors that contribute to quality of life. The ability to perform ADL for persons experiencing severe/profound intellectual disability (ID) may be reduced due to their cognitive and physical capacities. However, until recently, the impact of the significantly prevalent visual impairments on the performance of activities of daily living has not yet been revealed within this group. The purpose of this prospective cross-sectional study was to investigate the impact of visual impairment on the performance of activities of daily living for persons with a severe/profound intellectual disability. The Barthel Index (BI) and Comfortable Walking Speed (CWS) were used to measure the ability of performing activities of daily living (ADL) in 240 persons with severe/profound ID and having Gross Motor Functioning Classification System (GMFCS) levels I, II or III; this included 120 persons with visual impairment. The impact of visual impairment on ADL was analyzed with linear regression. The results of the study demonstrated that visual impairment slightly affects the ability of performing activities of daily living (BI) for persons experiencing a severe/profound intellectual disability. GMFCS Levels II or III, profound ID level, and visual impairment each have the effect of lowering BI scores. GMFCS Levels II or III, and profound ID level each have the effect of increasing CWS scores, which indicates a lower walking speed. A main effect of visual impairment is present on CWS, but our results do show a substantive interaction effect between GMFCS level III and visual impairment on Comfortable Walking Speed in persons with a severe/profound intellectual disability. Visual impairment has a slight effect on ability to perform ADL in persons experiencing severe/profound ID. Copyright © 2015 Elsevier Ltd. All rights reserved.

Objective To investigate, using accelerometers, the levels of physical activity being undertaken by individuals with intellectual disabilities with and without Down's syndrome. Methods One hundred and fifty two individuals with intellectual disabilities aged 12–70 years from East and South-East England. Physical activity levels in counts per minute (counts/min), steps per day (steps/day), and minutes of sedentary, light, moderate, vigorous, and moderate to vigorous physical activity (MVPA) measured with a uni-axial accelerometer (Actigraph GT1M) for seven days. Results No individuals with intellectual disabilities met current physical activity recommendations. Males were more active than females. There was a trend for physical activity to decline and sedentary behaviour to increase with age, and for those with more severe levels of intellectual disability to be more sedentary and less physically active, however any relationship was not significant when adjusted for confounding variables. Participants with Down's syndrome engaged in significantly less physical activity than those with intellectual disabilities without Down's syndrome and levels of activity declined significantly with age. Conclusions Individuals with intellectual disabilities, especially those with Down's syndrome may be at risk of developing diseases associated with physical inactivity. There is a need for well-designed, accessible, preventive health promotion strategies and interventions designed to raise the levels of physical activity for individuals with intellectual disabilities. We propose that there are physiological reasons why individuals with Down's syndrome have particularly low levels of physical activity that also decline markedly with age. PMID:22205957

Inhibition of RAS activation due to a homozygous ezrin variant in patients with profound intellectual disability.

Gain-of-function alterations in several components and modulators of the Ras-MAPK pathway lead to dysregulation of the pathway and cause a broad spectrum of autosomal dominant developmental disorders, collectively known as RASopathies. These findings demonstrate the importance of tight multilevel Ras regulation to safeguard signaling output and prevent aberrant activity. We have recently identified ezrin as a novel regulatory element required for Ras activation. Homozygosity mapping and exome sequencing have now revealed the first presumably disease-causing variant in the coding gene EZR in two siblings with a profound intellectual disability. Localization and membrane targeting of the altered ezrin protein appeared normal but molecular modeling suggested protein interaction surfaces to be disturbed. Functional analysis revealed that the altered ezrin protein is no longer able to bind Ras and facilitate its activation. Furthermore, expression of the altered ezrin protein in different cell lines resulted in abnormal cellular processes, including reduced proliferation and neuritogenesis, thus revealing a possible mechanism for its phenotype in humans. To our knowledge, this is the first report of an autosomal recessively inherited loss-of-function mutation causing reduced Ras activity and thus extends and complements the pathogenicity spectrum of known Ras-MAPK pathway disturbances. © 2014 WILEY PERIODICALS, INC.

Life-long intellectual activities mediate the predictive effect of early education on cognitive impairment in centenarians: a retrospective study.

PubMed

Kliegel, M; Zimprich, D; Rott, C

2004-09-01

The purpose of this study was to examine the hypothesis of whether early education and/or maintaining intellectual activities over the life-course have the power to protect against cognitive impairment even in extremely old adults. Ninety centenarians from the population-based Heidelberg Centenarian Study were assessed with a modified version of the Mini Mental State Exam (MMSE). Data about education, occupational status, and life-long intellectual activities in four selected domains were obtained. Results demonstrated that 52% of the sample showed mild-to-severe cognitive impairment. Analyzing the influence of early education, occupational status, and intellectual activities on cognitive status we applied several (logistic) regression analyses. Results revealed independent, significant and strong influence of both formal school education and intellectual activities on the cognitive status in very late life, even after controlling for occupational status. However, about one fourth of the effect of early education on cognitive status was exerted indirectly via the assessed intellectual activities. In summary, the present study provides first evidence for the conclusion that even with regard to cognitive performance in very old age, both early education and life-long intellectual activities seem to be of importance.

Cognitive predictors of adaptive functioning in children with symptomatic epilepsy.

PubMed

Kerr, Elizabeth N; Fayed, Nora

2017-10-01

The current study sought to understand the contribution of the attention and working memory challenges experienced by children with active epilepsy without an intellectual disability to adaptive functioning (AF) while taking into account intellectual ability, co-occurring brain-based psychosocial diagnoses, and epilepsy-related variables. The relationship of attention and working memory with AF was examined in 76 children with active epilepsy with intellectual ability above the 2nd percentile recruited from a tertiary care center. AF was measured using the Scales of Independent Behavior-Revised (SIB-R) and compared with norm-referenced data. Standardized clinical assessments of attention span, sustained attention, as well as basic and more complex working memory were administered to children. Commonality analysis was used to investigate the importance of the variables with respect to the prediction of AF and to construct parsimonious models to elucidate the factors most important in explaining AF. Seventy-one percent of parents reported that their child experienced mild to severe difficulties with overall AF. Similar proportions of children displayed limitations in domain-specific areas of AF (Motor, Social/Communication, Person Living, and Community Living). The reduced models for Broad and domain-specific AF produced a maximum of seven predictor variables, with little loss in overall explained variance compared to the full models. Intellectual ability was a powerful predictor of Broad and domain-specific AF. Complex working memory was the only other cognitive predictor retained in each of the parsimonious models of AF. Sustained attention and complex working memory explained a large amount of the total variance in Motor AF. Children with a previously diagnosed comorbidity displayed lower Social/Communication, Personal Living, and Broad AF than those without a diagnosis. At least one epilepsy-related variable appeared in each of the reduced models, with age of seizure onset and seizure type (generalized or partial) being the main predictors. Intellectual ability was the most powerful predictor of AF in children with epilepsy whose intellectual functioning was above the 2nd percentile. Co-occurring brain-based cognitive and psychosocial issues experienced by children with living epilepsy, particularly complex working memory and diagnosed comorbidities, contribute to AF and may be amenable to intervention.

The effectiveness of psychosocial interventions for children with a psychiatric disorder and mild intellectual disability to borderline intellectual functioning: A systematic literature review and meta-analysis.

2016-01-01

Children with intellectual disability frequently have difficulties in adapting to their environment. The extent of the experienced problems does not only depend on cognitive functioning but is influenced by other factors, such as the presence of a psychiatric disorder or other brain disorders, or adverse environmental factors. Several epidemiological studies show that children with intellectual disabilities are at an increased risk to develop psychiatric disorders. This is also true for youth with a mild intellectual disability and even those with borderline intellectual functioning (mild to borderline intellectual disability (MBID)). Psychiatric disorders are often overlooked because behavioral problems are rather attributed to the intellectual disability. Consequently, effective psychiatric interventions, which are needed to improve the level of functioning, are not applied. This review aimed to systematically evaluate the currently available, qualitatively sound research concerning the effectiveness of psychosocial interventions, specifically directed at psychiatric disorders in children with MBID. Assessed for eligibility were 1409 unique reports, and the review ultimately included only 12 reports. Review of the results and meta-analyses showed that the majority of studies suffer from multiple limitations and that methodological variations between studies are extensive. This possibly reflects the high variance of factors that may be involved in MBID. It will be important in future research to address multi-causality. © The Author(s) 2015.

Relationships between visual-motor and cognitive abilities in intellectual disabilities.

2007-06-01

The neurobiological hypothesis supports the relevance of studying visual-perceptual and visual-motor skills in relation to cognitive abilities in intellectual disabilities because the defective intellectual functioning in intellectual disabilities is not restricted to higher cognitive functions but also to more basic functions. The sample was 102 children 6 to 16 years old and with different severities of intellectual disabilities. Children were administered the Wechsler Intelligence Scale for Children, the Bender Visual Motor Gestalt Test, and the Developmental Test of Visual Perception, and data were also analysed according to the presence or absence of organic anomalies, which are etiologically relevant for mental disabilities. Children with intellectual disabilities had deficits in perceptual organisation which correlated with the severity of intellectual disabilities. Higher correlations between the spatial subtests of the Developmental Test of Visual Perception and the Performance subtests of the Wechsler Intelligence Scale for Children suggested that the spatial skills and cognitive performance may have a similar basis in information processing. Need to differentiate protocols for rehabilitation and intervention for recovery of perceptual abilities from general programs of cognitive stimulations is suggested.

As physical activity can prevent overweight and promote general health, the aim was to investigate the amount of physical activity among adolescent and young adult women and men with intellectual disability (ID), compared to age-matched control groups without intellectual disability. A further aim was to examine whether physical activity level was associated with the body mass index (BMI). Fifty-two adolescent and young adult women and men with intellectual disability and 48 without intellectual disability, between the ages 16 and 20 years, BMIs ranging from 16.3 to 50.3 kg/m(2) , were measured for number of steps taken with a pedometer for five consecutive days (Sunday-Thursday). The only group to meet recommendations regarding number of steps (10 000-12 000/day) was women without intellectual disability. No significant associations were found between total number of steps taken and BMI. As the majority of adolescents and young adults with intellectual disability, especially women, did not reach recommended activity levels regardless of their BMIs, this call for broad measures to increase physical activity. © 2015 John Wiley & Sons Ltd.

2013-09-01

We examined the implications of using the Full Scale IQ (FSIQ) versus the General Abilities Index (GAI) for determination of intellectual disability using the Wechsler Intelligence Scales for Children, fourth edition (WISC-IV). Children referred for neuropsychological assessment (543 males, 290 females; mean age 10y 5mo, SD 2y 9mo, range 6-16y) were administered the WISC-IV and the Adaptive Behavior Assessment System, second edition (ABAS-II). GAI and FSIQ were highly correlated; however, fewer children were identified as having intellectual disability using GAI (n=159) than when using FSIQ (n=196). Although the 44 children classified as having intellectual disability based upon FSIQ (but not GAI) had significantly higher adaptive functioning scores than those meeting intellectual disability criteria based upon both FSIQ and GAI, mean adaptive scores still fell within the impaired range. FSIQ and GAI were comparable in predicting impairments in adaptive functioning. Using GAI rather than FSIQ in intellectual disability diagnostic decision-making resulted in fewer individuals being diagnosed with intellectual disability; however, the mean GAI of the disqualified individuals was at the upper end of criteria for intellectual impairment (standard score 75), and these individuals remained adaptively impaired. As GAI and FSIQ were similarly predictive of overall adaptive functioning, the use of GAI for intellectual disability diagnostic decision-making may be of limited value. © 2013 Mac Keith Press.

Oligophrenin-1 (OPHN1), a Gene Involved in X-Linked Intellectual Disability, Undergoes RNA Editing and Alternative Splicing during Human Brain Development

2014-01-01

Oligophrenin-1 (OPHN1) encodes for a Rho-GTPase-activating protein, important for dendritic morphogenesis and synaptic function. Mutations in this gene have been identified in patients with X-linked intellectual disability associated with cerebellar hypoplasia. ADAR enzymes are responsible for A-to-I RNA editing, an essential post-transcriptional RNA modification contributing to transcriptome and proteome diversification. Specifically, ADAR2 activity is essential for brain development and function. Herein, we show that the OPHN1 transcript undergoes post-transcriptional modifications such as A-to-I RNA editing and alternative splicing in human brain and other tissues. We found that OPHN1 editing is detectable already at the 18th week of gestation in human brain with a boost of editing at weeks 20 to 33, concomitantly with OPHN1 expression increase and the appearance of a novel OPHN1 splicing isoform. Our results demonstrate that multiple post-transcriptional events occur on OPHN1, a gene playing an important role in brain function and development. PMID:24637888

O-linked β-N-acetyl- D -glucosamine (O-GlcNAc) transferase (OGT) regulates protein O-GlcNAcylation, an essential post-translational modification that is abundant in the brain. Recently, OGT mutations have been associated with intellectual disability, although it is not understood how they affect OGT structure and function. Using a multi-disciplinary approach we show that the L254F OGT mutation leads to conformational changes of the tetratricopeptide repeats and reduced activity, revealing the molecular mechanisms contributing to pathogenesis.

2015-12-01

FOXP1 (forkhead box protein P1) is a transcription factor involved in the development of several tissues, including the brain. An emerging phenotype of patients with protein-disrupting FOXP1 variants includes global developmental delay, intellectual disability and mild to severe speech/language deficits. We report on a female child with a history of severe hypotonia, autism spectrum disorder and mild intellectual disability with severe speech/language impairment. Clinical exome sequencing identified a heterozygous de novo FOXP1 variant c.1267_1268delGT (p.V423Hfs*37). Functional analyses using cellular models show that the variant disrupts multiple aspects of FOXP1 activity, including subcellular localization and transcriptional repression properties. Our findings highlight the importance of performing functional characterization to help uncover the biological significance of variants identified by genomics approaches, thereby providing insight into pathways underlying complex neurodevelopmental disorders. Moreover, our data support the hypothesis that de novo variants represent significant causal factors in severe sporadic disorders and extend the phenotype seen in individuals with FOXP1 haploinsufficiency.

The Sexuality of Adults with Intellectual Disability in Poland.

PubMed

Kijak, Remigiusz

2013-06-01

Sexuality is one of the most important aspects of human life that relates to sex, one's identification, sexual role, sexual preferences, eroticism, pleasure and intimacy. It fulfils such functions as procreative, hedonistic and relationship-building as well as constitutes an integral part of human's personality. The sexuality of people with intellectual disability is a special case - both from medical, pedagogical, psychological and ethical point of view. Little available research shows that it may become a significant factor that modifies their psychological and sexual functioning. The basic poll involved altogether 133 people with mild intellectual disability. The work was carried out in 11 schools and special institutions of three provinces in Poland: kujawsko - pomorskie, wielkopolskie and dolnośląskie (provinces of Kujavy and Pomerania, Great Poland and Lower Silesia) The respondents qualified to take part in the poll constituted a very uniform group - homogenous as regards their age of 18-25 as well as IQ level that was average for the people with higher degree of intellectual disability (HDID). Their age was of importance as in that life period one can observe the formation of first partner relationships with the clear aim of establishing a family. It is accompanied by a quick development of sexual desire and taking up various forms of sexual activity. People with intellectual disability don't form a homogenous group as regards their psychological and sexual development. In this group, one can observe both different forms of clinical mental handicap which definitely affects the whole process of sexual development. The sexual development is delayed by an average period of 3 years. The people with intellectual disability take up mostly autoerotic behaviour whereas partner relationships wthin that group are more seldom. The phenomenon of sexuality of people with higher degree of intellectual disability is an issue that needs further constant analysis. The research has also made it possible to detect what kind of sexual behaviour people with intellectual disability undertake and the value of sexuality for such people. The article deals also with some important dilemmas connected with sexual education and what factors trigger off incorrect sexual reaction including their lack in the above mentioned group.

2013-01-01

Aim We examined the implications of using the Full Scale Intelligence Quotient (FSIQ) versus the General Abilities Index (GAI) for determination of intellectual disability using the Wechsler Intelligence Scales for Children, fourth edition (WISC-IV). Method Children referred for neuropsychological assessment (543 males, 290 females; mean age 10y 5mo, SD 2y 9mo, range 6–16y) were administered the WISC-IV and the Adaptive Behavior Assessment System, Second Edition (ABAS-II). Results GAI and FSIQ were highly correlated; however, fewer children were identified as having intellectual disability using GAI (n=159) than when using FSIQ (n=196). Although the 44 children classified as having intellectual disability based upon FSIQ (but not GAI) had significantly higher adaptive functioning scores than those meeting intellectual disability criteria based upon both FSIQ and GAI, mean adaptive scores still fell within the impaired range. FSIQ and GAI were comparable in predicting impairments in adaptive functioning. Interpretation Using GAI rather than FSIQ in intellectual disability diagnostic decision making resulted in fewer individuals being diagnosed with intellectual disability; however, the mean GAI of the disqualified individuals was at the upper end of criteria for intellectual impairment (standard score 75), and these individuals remained adaptively impaired. As GAI and FSIQ were similarly predictive of overall adaptive functioning, the use of GAI for intellectual disability diagnostic decision making may be of limited value. PMID:23859669

Doing nothing: adults with disabilities with no daily activities and their siblings.

PubMed

Taylor, Julie Lounds; Hodapp, Robert M

2012-01-01

A significant concern of parents and professionals is that adults with intellectual and developmental disabilities will go without regular educational-vocational activities. The authors examined predictors of such inactivity in individuals with intellectual and developmental disabilities, as well as how inactivity related to their sibling's well-being and the sibling relationship. Participants included 796 siblings of adults with intellectual and developmental disabilities who responded to a web-based survey. Nearly 13% of adults with intellectual and developmental disabilities were without daytime activities; these adults had more emotional-behavioral and health problems, were more underserved by the formal service system, and had parents who were less able to provide care. Although siblings of adults without activities reported more depressive symptoms, worse health, and less close sibling relationships, inactivity no longer predicted these problems after controlling for characteristics that predisposed adults with intellectual and developmental disabilities to have no activities.

Although factors associated with falls might differ between men and women, no large-scale studies were conducted to examine the sex difference of risk factors for falls in Japanese elderly. The purpose of this study was to examine fall risk factors and sex differences among community-dwelling elderly individuals using a complete survey of the geriatric population in Kameoka city. A self-administered questionnaire survey was conducted with 18,231 community-dwelling elderly individuals aged 65 years or over in Kameoka city, Kyoto Prefecture, between July and August 2011, excluding people who were publicly certified with a long-term care need of grade 3 or higher. The questionnaire was individually distributed and collected via mail. Out of 12,159 responders (recovery rate of 72.2%), we analyzed the data of 12,054 elderly individuals who were not certified as having long-term care needs. The questionnaire was composed of basic attributes, a simple screening test for fall risk, the Kihon Check List with 25 items, and the Tokyo Metropolitan Institute of Gerontology (TMIG) index of competence with 13 items. These items were grouped into nine factors: motor function, malnutrition, oral function, houseboundness, forgetfulness, depression, Instrumental Activity of Daily Living (IADL), intellectual activities, and social role. Of all the respondents, 20.8% experienced falls within the last year, and 26.6% were classified as having high fall risk. Fall risk increased with age in both sexes, and risk in all age groups was higher for women than for men. All factors were significantly associated with fall risk in both sexes. After controlling for these factors, a significant relationship was found between fall risk and motor function, malnutrition, oral function, forgetfulness, depression, and IADL in men and motor function, oral function, forgetfulness, depression, and IADL in women. The deterioration of motor function was associated with three-times-higher risk than non-deterioration of motor function. In addition, significant interaction was found in sex×malnutrition, oral function, IADL, and intellectual activities; malnutrition and low oral function were stronger factors in men than in women; and IADL and intellectual activities were stronger factors in women than in men. One in five community-dwelling independent elderly individuals experienced falls in the last year, and one in four had high fall risk. We found a significant relationship between fall risk and the nine factors, particularly deterioration of motor function in both sexes. Sex difference was observed for fall risk factors; therefore, a sex-specific support policy for fall prevention is necessary.

Discovery of previously undetected intellectual disability by psychological assessment: a study of consecutively referred child and adolescent psychiatric inpatients.

Pogge, David L; Stokes, John; Buccolo, Martin L; Pappalardo, Stephen; Harvey, Philip D

2014-07-01

Intellectual disability is associated with an increased risk of behavioral disturbances and also complicates their treatment. Despite increases in the sophistication of medical detection of early risk for intellectual disability, there is remarkably little data about the detection of intellectual disability in cases referred for psychiatric treatment. In this study, we used a 10-year sample of 23,629 consecutive child and adolescent admissions (ages between 6 and 17) to inpatient psychiatric treatment. Eleven percent (n=2621) of these cases were referred for psychological assessment and were examined with a general measure of intellectual functioning (i.e., WISC-IV). Of these cases, 16% had Full Scale IQs below 70. Of the cases whose therapists then referred them for formal assessment of their adaptive functioning (i.e., ABAS-II) 81% were found to have composite scores below 70 as well. Only one of the cases whose Full Scale IQ was less than 70 had a referral diagnosis of intellectual disability. Cases with previously undetected intellectual disability were found to be significantly more likely to have a diagnosis of a psychotic disorder and less likely to have a diagnosis of mood disorder than cases with IQs over 70. Disruptive behavior disorder diagnoses did not differ as a function of intellectual performance. These data suggest a high rate of undetected intellectual disability in cases with a psychiatric condition serious enough to require hospitalization and this raises the possibility that many such cases may be misdiagnosed, the basis of their problems may be misconceptualized, and they may be receiving treatments that do not take into account their intellectual level.

The evolving understanding of the construct of intellectual disability.

PubMed

Schalock, Robert L

2011-12-01

This article addresses two major areas concerned with the evolving understanding of the construct of intellectual disability. The first part of the article discusses current answers to five critical questions that have revolved around the general question, "What is Intellectual Disability?" These five are what to call the phenomenon, how to explain the phenomenon, how to define the phenomenon and determine who is a member of the class, how to classify persons so defined and identified, and how to establish public policy regarding such persons. The second part of the article discusses four critical issues that will impact both our future understanding of the construct and the approach taken to persons with intellectual disability. These four critical issues relate to the conceptualisation and measurement of intellectual functioning, the constitutive definition of intellectual disability, the alignment of clinical functions related to diagnosis, classification, and planning supports, and how the field resolves a number of emerging epistemological issues.

To identify the underlying genetic defect in a patient with intellectual disability, seizures, ataxia, macrothrombocytopenia, renal and cardiac involvement, and abnormal protein glycosylation. Genetic studies involved homozygosity mapping by 250K single nucleotide polymorphism array and SLC35A1 sequencing. Functional studies included biochemical assays for N-glycosylation and mucin-type O-glycosylation and SLC35A1-encoded cytidine 5'-monophosphosialic acid (CMP-sialic acid) transport after heterologous expression in yeast. We performed biochemical analysis and found combined N- and O-glycosylation abnormalities and specific reduction in sialylation in this patient. Homozygosity mapping revealed homozygosity for the CMP-sialic acid transporter SLC35A1. Mutation analysis identified a homozygous c.303G > C (p.Gln101His) missense mutation that was heterozygous in both parents. Functional analysis of mutant SLC35A1 showed normal Golgi localization but 50% reduction in transport activity of CMP-sialic acid in vitro. We confirm an autosomal recessive, generalized sialylation defect due to mutations in SLC35A1. The primary neurologic presentation consisting of ataxia, intellectual disability, and seizures, in combination with bleeding diathesis and proteinuria, is discriminative from a previous case described with deficient sialic acid transporter. Our study underlines the importance of sialylation for normal CNS development and regular organ function.

2015-12-01

The spinothalamic pathway mediates sensations of temperature, pain, and touch. These functions seem impaired in children with Down syndrome (DS), but have not been extensively examined in adults. The objective of the present study was to compare the spinothalamic-mediated sensory functions between adults with DS and adults from the general population and to examine in the DS group the relationship between the sensory functions and level of intellectual functioning. Quantitative sensory testing (QST) was performed in 188 adults with DS (mean age 37.5 years) and 142 age-matched control participants (median age 40.5 years). Temperature, pain, and touch were evaluated with tests for cold-warm discrimination, sharp-dull discrimination (pinprick), and tactile threshold, respectively. Level of intellectual functioning was estimated with the Social Functioning Scale for Intellectual Disability (intellectual disability level) and the Wechsler Preschool and Primary Scale of Intelligence--Revised (intelligence level). Overall, the difference in spinothalamic-mediated sensory functions between the DS and control groups was not statistically significant. However, DS participants with a lower intelligence level had a statistically significant lower performance on the sharp-dull discrimination test than DS participants with higher intelligence level (adjusted p=.006) and control participants (adjusted p=.017). It was concluded that intellectual functioning level is an important factor to take into account for the assessment of spinothalamic-mediated sensory functioning in adults with DS: a lower level could coincide with impaired sensory functioning, but could also hamper QST assessment.

2013-01-01

Neurofibromatosis-1 is the most common single gene disorder affecting 1 in 3000. In children, it is associated not only with physical features but also with attention and learning problems. Research has identified a downward shift in intellectual functioning as well, but to date, there are no published studies about the everyday adaptive behavior of children with NF1. In this study, parental reports of adaptive behavior of 61 children with NF1 ages 3 through 8 were compared to an unaffected contrast group (n = 55) that comprised siblings and community members. Significant group differences in adaptive skills were evident and were largely related to group differences in intellectual functioning. In a subsample of children with average-range intellectual functioning, group differences in parent-reported motor skills were apparent even after controlling statistically for group differences in intellectual functioning. The implications of the findings for the care of children with NF1 are discussed.

Functional properties of behaviour problems depending on level of intellectual disability.

Medeiros, K; Rojahn, J; Moore, L L; van Ingen, D J

2014-02-01

Behaviour problems are common among individuals with intellectual disabilities (ID) especially in those with more severe forms. The determination of the functional profile of a targeted behaviour has important implications for the design of customised behavioural interventions. We investigated the relationship between the level of ID and the functional profile of aggression, stereotypy and self-injurious behaviour (SIB) using the Questions about Behavioural Function (QABF). Two staff members at two time points completed the QABF for each of 115 adults with varying levels of ID participating in a day training and habilitation programme. Our results suggest that there is a differential relationship between the functions of behaviour problems and level of ID. While SIB is more often seen by raters to be maintained by escape of social demands and by attaining access to tangible items with the decline of the intellectual level, aggressive and stereotypic behaviours were identified more often as serving multiple functions equally across functioning level. © 2013 The Authors.

The aim of this study was to indicate the relationship between periodontal status and intellectual function in the elderly. Periodontal status has been shown to be related to demographic, socioeconomic, and psychological status. Intellectual function is a significant indicator of health status. Nevertheless, the relationship between periodontal status and intellectual function has not been elucidated in detail among the elderly. A total of 152 community-dwelling elderly persons, aged 70-74 years, were enrolled in the study. Periodontal status was evaluated using the WHO Community Periodontal Index of Treatment Needs (CPITN). Intellectual function was assessed by four neuropsychological tests: Raven's Coloured Progressive Matrices (RCPM) test, the Verbal Paired Associates 1 (VerPA) task and the Visual Paired Associates 1 (VirPA) task, extracted from the Wechsler Memory Scale Revised Edition, and the Block Design subtest, extracted from the Wechsler Adult Intelligence Scales, Third Edition. Correlations between CPITN and each test were examined using Spearman rank correlation coefficients. The ordinal regression model was constructed with CPITN as the dependent variable and neuropsychological test as the principal independent variable to adjust for demographic factors, general health, lifestyle and oral health behaviour. Significant correlations were found between the RCPM test, the VerPA task, the Visual Paired Associates 1 and CPITN. In the ordinal regression model, CPITN was significantly related to measures of RCPM after adjusting for demographic factors, general health status, lifestyle and oral health behaviour. Intellectual function is considered a significant indicator of periodontal status among community-dwelling elderly persons. © 2011 The Gerodontology Society and John Wiley & Sons A/S.

Movement cognition and narration of the emotions treatment versus standard speech therapy in the treatment of children with borderline intellectual functioning: a randomized controlled trial.

PubMed

2017-04-20

Borderline intellectual functioning (BIF) is defined as a "health meta-condition… characterized by various cognitive dysfunctions associated with an intellectual quotient (IQ) between 71 and 85 which determines a deficit in the individual's functioning both in the restriction of activities and in the limitation of social participation". It can be caused by many factors, including a disadvantaged background and prematurity. BIF affects 7-12% of primary school children that show academic difficulties due to poor executive functioning. In many children with BIF, language, movement and social abilities are also affected, making it difficult to take part in daily activities. Dropping out of school and psychological afflictions such as anxiety and depression are common in children with BIF. This study investigates whether an intensive rehabilitation program that involves all of the areas affected in children with BIF (Movement, Cognition and Narration of emotions, MCNT) is more effective than Standard Speech Therapy (SST). This is a multicenter interventional single blind randomized controlled study. Children aged between 6 to 11 years who attend a mainstream primary school and have multiple learning difficulties, behavioral problems and an IQ ranging between 85 to 70 have been enrolled. Participants are randomly allocated to one of three groups. The first group receives individual treatment with SST for 45 min, twice a week for 9 months. The second group receives the experimental treatment MCNT for 3 h per day, 5 days/ week for 9 months and children work in small groups. The third group consists of children on a waiting list for the SST for nine months. BIF is a very frequent condition with no ad hoc treatment. Over the long term, there is a high risk to develop psychiatric disorders in adulthood. Due to its high social impact, we consider it very important to intervene during childhood so as to intercept the remarkable plasticity of the developing brain.

In this monograph, we ask whether various kinds of intellectual, physical, and social activities produce cognitive enrichment effects-that is, whether they improve cognitive performance at different points of the adult life span, with a particular emphasis on old age. We begin with a theoretical framework that emphasizes the potential of behavior to influence levels of cognitive functioning. According to this framework, the undeniable presence of age-related decline in cognition does not invalidate the view that behavior can enhance cognitive functioning. Instead, the course of normal aging shapes a zone of possible functioning, which reflects person-specific endowments and age-related constraints. Individuals influence whether they function in the higher or lower ranges of this zone by engaging in or refraining from beneficial intellectual, physical, and social activities. From this point of view, the potential for positive change, or plasticity, is maintained in adult cognition. It is an argument that is supported by newer research in neuroscience showing neural plasticity in various aspects of central nervous system functioning, neurochemistry, and architecture. This view of human potential contrasts with static conceptions of cognition in old age, according to which decline in abilities is fixed and individuals cannot slow its course. Furthermore, any understanding of cognition as it occurs in everyday life must make a distinction between basic cognitive mechanisms and skills (such as working-memory capacity) and the functional use of cognition to achieve goals in specific situations. In practice, knowledge and expertise are critical for effective functioning, and the available evidence suggests that older adults effectively employ specific knowledge and expertise and can gain new knowledge when it is required. We conclude that, on balance, the available evidence favors the hypothesis that maintaining an intellectually engaged and physically active lifestyle promotes successful cognitive aging. First, cognitive-training studies have demonstrated that older adults can improve cognitive functioning when provided with intensive training in strategies that promote thinking and remembering. The early training literature suggested little transfer of function from specifically trained skills to new cognitive tasks; learning was highly specific to the cognitive processes targeted by training. Recently, however, a new generation of studies suggests that providing structured experience in situations demanding executive coordination of skills-such as complex video games, task-switching paradigms, and divided attention tasks-train strategic control over cognition that does show transfer to different task environments. These studies suggest that there is considerable reserve potential in older adults' cognition that can be enhanced through training. Second, a considerable number of studies indicate that maintaining a lifestyle that is intellectually stimulating predicts better maintenance of cognitive skills and is associated with a reduced risk of developing Alzheimer's disease in late life. Our review focuses on longitudinal evidence of a connection between an active lifestyle and enhanced cognition, because such evidence admits fewer rival explanations of observed effects (or lack of effects) than does cross-sectional evidence. The longitudinal evidence consistently shows that engaging in intellectually stimulating activities is associated with better cognitive functioning at later points in time. Other studies show that meaningful social engagement is also predictive of better maintenance of cognitive functioning in old age. These longitudinal findings are also open to important rival explanations, but overall, the available evidence suggests that activities can postpone decline, attenuate decline, or provide prosthetic benefit in the face of normative cognitive decline, while at the same time indicating that late-life cognitive changes can result in curtailment of activities. Given the complexity of the dynamic reciprocal relationships between stimulating activities and cognitive function in old age, additional research will be needed to address the extent to which observed effects validate a causal influence of an intellectually engaged lifestyle on cognition. Nevertheless, the hypothesis that an active lifestyle that requires cognitive effort has long-term benefits for older adults' cognition is at least consistent with the available data. Furthermore, new intervention research that involves multimodal interventions focusing on goal-directed action requiring cognition (such as reading to children) and social interaction will help to address whether an active lifestyle enhances cognitive function. Third, there is a parallel literature suggesting that physical activity, and aerobic exercise in particular, enhances older adults' cognitive function. Unlike the literature on an active lifestyle, there is already an impressive array of work with humans and animal populations showing that exercise interventions have substantial benefits for cognitive function, particularly for aspects of fluid intelligence and executive function. Recent neuroscience research on this topic indicates that exercise has substantial effects on brain morphology and function, representing a plausible brain substrate for the observed effects of aerobic exercise and other activities on cognition. Our review identifies a number of areas where additional research is needed to address critical questions. For example, there is considerable epidemiological evidence that stress and chronic psychological distress are negatively associated with changes in cognition. In contrast, less is known about how positive attributes, such as self-efficacy, a sense of control, and a sense of meaning in life, might contribute to preservation of cognitive function in old age. It is well known that certain personality characteristics such as conscientiousness predict adherence to an exercise regimen, but we do not know whether these attributes are also relevant to predicting maintenance of cognitive function or effective compensation for cognitive decline when it occurs. Likewise, more information is needed on the factors that encourage maintenance of an active lifestyle in old age in the face of elevated risk for physiological decline, mechanical wear and tear on the body, and incidence of diseases with disabling consequences, and whether efforts to maintain an active lifestyle are associated with successful aging, both in terms of cognitive function and psychological and emotional well-being. We also discuss briefly some interesting issues for society and public policy regarding cognitive-enrichment effects. For example, should efforts to enhance cognitive function be included as part of a general prevention model for enhancing health and vitality in old age? We also comment on the recent trend of business marketing interventions claimed to build brain power and prevent age-related cognitive decline, and the desirability of direct research evidence to back claims of effectiveness for specific products. © 2009 Association for Psychological Science.

Protein synthesis regulation via mammalian target of rapamycin complex 1 (mTORC1) signaling pathway has key roles in neural development and function, and its dysregulation is involved in neurodevelopmental disorders associated with autism and intellectual disability. mTOR regulates assembly of the translation initiation machinery by interacting with the eukaryotic initiation factor eIF3 complex and by controlling phosphorylation of key translational regulators. Collybistin (CB), a neuron-specific Rho-GEF responsible for X-linked intellectual disability with epilepsy, also interacts with eIF3, and its binding partner gephyrin associates with mTOR. Therefore, we hypothesized that CB also binds mTOR and affects mTORC1 signaling activity in neuronal cells. Here, by using induced pluripotent stem cell-derived neural progenitor cells from a male patient with a deletion of entire CB gene and from control individuals, as well as a heterologous expression system, we describe that CB physically interacts with mTOR and inhibits mTORC1 signaling pathway and protein synthesis. These findings suggest that disinhibited mTORC1 signaling may also contribute to the pathological process in patients with loss-of-function variants in CB.

Abstract Background: Schizophrenia (SZ) is often characterized by cognitive and intellectual impairment. However, there is much heterogeneity across individuals, suggesting different trajectories of the illness. Recent findings have shown brain volume differences across subgroups of individuals with psychosis (SZ and bipolar disorder), such that those with intellectual and cognitive impairments presented evidence of early cerebral disruption, while those with cognitive but not intellectual impairments showed evidence of progressive brain abnormalities. Our aim was to investigate the relations of cognition and intellectual functioning with brain structure abnormalities in a sample of SZ compared to unaffected individuals. Methods: 92 individuals with SZ and 94 healthy controls part of the Northwestern University Schizophrenia Data and Software Tool (NUSDAST) underwent neuropsychological assessment and structural magnetic resonance imaging (MRI). Individuals with SZ were divided into subgroups according their estimated premorbid crystallized intellectual (ePMC-IQ) and cognitive performance. Brain volumes differences were investigated across groups. Results: SZ with ePMC-IQ and cognitive impairments had reduced total brain volume (TBV), intracranial volume (ICV), TBV corrected for ICV, and cortical gray matter volume, as well as reduced cortical thickness, and insula volumes. SZ with cognitive impairment but intact ePMC-IQ showed only reduced cortical gray matter volume and cortical thickness. Conclusions: These data provide additional evidence for heterogeneity in SZ. Impairments in cognition associated with reduced ePMC-IQ were related to evidence of broad brain structural alterations, including suggestion of early cerebral disruption. In contrast, impaired cognitive functioning in the context of more intact intellectual functioning was associated with cortical alterations that may reflect neurodegeneration. PMID:27369471

A previous study suggested that mothers of 5-year-old children with borderline intellectual functioning displayed lower positive engagement with their children as compared with both mothers of typically developing children and mothers of children with significant developmental delays (Fenning, Baker, Baker, & Crnic, 2007). The current study integrated father data and followed these families over the subsequent 1-year period. Parent and child behavior were coded from naturalistic home observations at both waves. Results revealed that mothers of children with borderline intellectual functioning displayed a greater increase in negative-controlling parenting from child age 5 to 6 than did other mothers; fathers displayed more negative-controlling behavior in comparison to fathers of typically developing children. In addition, children with borderline intellectual functioning themselves exhibited a more significant escalation in difficult behavior than did typically developing children. Cross-lagged analyses for the sample as a whole indicated that maternal negative-controlling behavior predicted subsequent child difficulties, whereas negative paternal behavior was predicted by earlier child behavior. In conjunction with evidence from Fenning et al. (2007), these findings suggest a complex, dynamic, and systemic developmental pattern in the emotional behavior of families of children with borderline intellectual functioning. Implications and areas in need of additional research are discussed. PsycINFO Database Record (c) 2014 APA, all rights reserved.

Population aging has prompted considerable interest in identifying modifiable factors that may help protect the brain and its functions. Collectively, epidemiological studies show that leisure activities with high mental and social demands are linked with better cognition in old age. The extent to which socio-intellectual activities relate to the brain's structure is, however, not yet fully understood. This systematic review and meta-analysis summarizes magnetic resonance imaging studies that have investigated whether cognitive and social activities correlate with measures of gray and white matter volume, white matter microstructure and white matter lesions. Across eighteen included studies (total n = 8429), activity levels were associated with whole-brain white matter volume, white matter lesions and regional gray matter volume, although effect sizes were small. No associations were found for global gray matter volume and the evidence concerning white matter microstructure was inconclusive. While the causality of the reviewed associations needs to be established, our findings implicate socio-intellectual activity levels as promising targets for interventions aimed at promoting healthy brain aging.

Lindenberger, U; Baltes, P B

1997-09-01

This study documents age trends, interrelations, and correlates of intellectual abilities in old and very old age (70-103 years) from the Berlin Aging Study (N = 516). Fourteen tests were used to assess 5 abilities: reasoning, memory, and perceptual speed from the mechanic (broad fluid) domain and knowledge and fluency from the pragmatic (broad crystallized) domain. Intellectual abilities had negative linear age relations, with more pronounced age reductions in mechanic than in pragmatic abilities. Interrelations among intellectual abilities were highly positive and did not follow the mechanic-pragmatic distinction. Sociobiographical indicators were less closely linked to intellectual functioning than sensory-sensorimotor variables, which predicted 59% of the total reliable variance in general intelligence. Results suggest that aging-induced biological factors are a prominent source of individual differences in intelligence in old and very old age.

To what extent do joint attention, imitation, and object play behaviors in infancy predict later communication and intellectual functioning in ASD?

PubMed

Poon, Kenneth K; Watson, Linda R; Baranek, Grace T; Poe, Michele D

2012-06-01

The extent to which early social communication behaviors predict later communication and intellectual outcomes was investigated via retrospective video analysis. Joint attention, imitation, and complex object play behaviors were coded from edited home videos featuring scenes of 29 children with ASD at 9-12 and/or 15-18 months. A quantitative interval recording of behavior and a qualitative rating of the developmental level were applied. Social communication behaviors increased between 9-12 and 15-18 months. Their mean level during infancy, but not the rate of change, predicted both Vineland Communication scores and intellectual functioning at 3-7 years. The two methods of measurement yielded similar results. Thus, early social communicative behaviors may play pivotal roles in the development of subsequent communication and intellectual functioning.

Cognitive reserve (CR) is a construct that originates from the observation of poor correspondence between brain damage and clinical symptoms. The aim of the study was to investigate the association between cognitive reserve (CR), brain reserve (BR) and cognitive functions and to evaluate whether CR might attenuate/moderate the negative impact of brain atrophy and lesion load on cognitive functions in multiple sclerosis (MS). To achieve these aims, ninety-eight relapsing-remitting MS patients underwent the brief repeatable battery of neuropsychological tests and Stroop test (ST). CR was assessed by vocabulary-based estimate of lifetime intellectual enrichment. All patients underwent a 3T MRI to assess T2-lesion load and atrophy measures, including normalized gray matter and white matter (nWMV) volumes. The BR was evaluated by maximal lifetime brain volume expressed by intracranial volume (ICV). Hierarchical regressions were used to investigate whether higher BR and/or CR is related to better cognitive performances after controlling for potentially confounding factors. The ICV was not associated with any cognitive tests. Intellectual enrichment was positively associated with performance on tests assessing memory, attention and information processing speed, verbal fluency and inhibitory control. Significant relationship between nWMV and ST was moderated by intellectual enrichment. In conclusion, the findings suggested that CR seems to mitigate cognitive dysfunction in MS patients and can reduce the negative impact of brain atrophy on inhibitory control, relevant for integrity of instrumental activities of daily living.

This study examines the association between late-life leisure activity participation and global cognitive decline in community-dwelling elderly Chinese in Hong Kong. Five hundred and five participants, not clinically demented at the baseline, were analysed in the follow-up study of a population-based community survey among Hong Kong Chinese aged 60 and over. Information regarding leisure activity participation, global cognitive function and important sociodemographic variables was collected. Late life leisure activity profiles were classified into intellectual, social, physical and recreational categories, and were measured by total hours per week, total frequency and total number of subtypes. Multivariate logistic regression analyses were used to evaluate the association between leisure activity participation at the baseline and the incidence of global cognitive decline at the 22-month follow-up. The incidence of global cognitive decline was defined as a one-point drop in z-score of the Cantonese version of the mini-mental state examination (CMMSE). At the follow-up, a higher level of participation in intellectual activities was significantly associated with a lower incidence of global cognitive decline as measured by both the total hours per week (multivariate-adjusted OR 0.97 (95% CI 0.94-0.99, p=0.003)), and the total number of subtypes (multivariate-adjusted OR 0.74 (95% CI 0.58-0.95, p=0.018)). A higher level of late-life intellectual activity participation was associated with less global cognitive decline among community-dwelling elderly Chinese in Hong Kong.

Sickle Cell Disease (SCD) is the most common genetic disease worldwide. Neurological events are among the most worrisome clinical complications of SCD and are frequently accompanied by cognitive impairment. Intellectual function in SCD may vary according to genetic and environmental factors. Immigrant children with SCD are increasing at a global level and display specific health care needs. The aim of our multicenter study was to describe the intellectual function of first generation African immigrants with SCD and the influence of sociodemographic factors on its characteristics. The Wechsler Intelligence Scales were administered to evaluate broad intellectual functions in children with SCD and in age-matched healthy siblings. Patients' clinical, socio-demographic, Magnetic Resonance Imaging (MRI) and Angiography (MRA) data were correlated to intellectual function scores. 68 children, mean age 8.95 years were evaluated. 72% spoke three languages, 21% two. FSIQ was <75 in 25% of the children. Mean VIQ was lower than PIQ in 75%. Mean verbal subtest scores were lower than performance scores. Female gender, number of languages spoken at home and mother's employment were associated with single subtest performances (p < 0.05). MRA was abnormal in 73.4% and MRI in 35.9%. No significant correlation was established between silent lesions and intellectual function, even if patients with lesions performed worse. Fifteen siblings performed better than patients on cognitive domains, including language (p < 0.05). Immigrant bilingual children with SCD seem to display a rate of cognitive impairment similar to their monolingual counterparts but a more pronounced and precocious onset of language difficulties. Adjunctive tests need to be considered in this group of patients to better define their specific deficits.

To explore the relationship between gross motor and intellectual function in children with cerebral palsy (CP). A cross-sectional study. Occupational therapy clinic. Children with CP (N=662; 281 girls, 381 boys; age range, 3-14y). Not applicable. Intelligence testing was carried out by means of the Wechsler Preschool and Primary Scale of Intelligence and the Wechsler Intelligence Scale for Children-Revised. Gross motor function level was determined by the Gross Motor Function Classification System Expanded and Revised (GMFCS E&R). Of the children, 10.4% were at level I of the GMFCS E&R, 38% at levels II and III, and 51.5% at levels IV and V. The lowest level of intelligence or profound intellectual disability was found in children with spastic quadriplegia (n=28, 62.2%). Children at the lowest levels (I-IV, GMFCS E&R) obtained higher ratings in terms of intelligence in comparison with children at level V. Based on the present results, the diagnosis was statistically related to the intellectual level as dependent variable (P<.01); accordingly, hypotonic, quadriplegic, and hemiplegic patients had the highest odds to assign higher ratings in abnormal intelligence, respectively. Sex and age were not statistically related to the dependent variable. The study results demonstrated a significant association between GMFCS E&R and intellectual function. Therefore, we suggest that particular attention should be paid to the intellectual level in terms of evaluations of gross motor function. These results, in respect, might be interested for occupational and physical therapists who are involved in rehabilitation programs for these children.

Physical inactivity is a leading risk factor for mortality. Adults with intellectual disability are extremely inactive, but less is known about physical activity levels in children and youth with intellectual disability. This paper examines the participation by adolescents and young adults with and without mild to moderate intellectual disability in sport/exercise. Secondary analysis was undertaken of Next Steps, an annual panel study that followed a cohort from early adolescence into adulthood. Participants with mild to moderate intellectual disability were identified through data linkage with educational records. Sport/exercise participation rates were consistently lower for adolescents and young people with mild to moderate intellectual disability than for their peers without intellectual disability. Matching participants on between-group differences in exposure to extraneous risk factors did not impact on these between-group differences in participation in sport/exercise. The results support limited existing evidence regarding the low level of participation of children and young people with intellectual disability in sport/exercise compared with their peers. Future work on promoting sport/exercise and physical activity in children and young people with intellectual disability may play a role in helping to reduce the health inequalities experienced by people with intellectual disability.

Emerging role of the KCNT1 Slack channel in intellectual disability.

PubMed

Kim, Grace E; Kaczmarek, Leonard K

2014-01-01

The sodium-activated potassium KNa channels Slack and Slick are encoded by KCNT1 and KCNT2, respectively. These channels are found in neurons throughout the brain, and are responsible for a delayed outward current termed I KNa. These currents integrate into shaping neuronal excitability, as well as adaptation in response to maintained stimulation. Abnormal Slack channel activity may play a role in Fragile X syndrome, the most common cause for intellectual disability and inherited autism. Slack channels interact directly with the fragile X mental retardation protein (FMRP) and I KNa is reduced in animal models of Fragile X syndrome that lack FMRP. Human Slack mutations that alter channel activity can also lead to intellectual disability, as has been found for several childhood epileptic disorders. Ongoing research is elucidating the relationship between mutant Slack channel activity, development of early onset epilepsies and intellectual impairment. This review describes the emerging role of Slack channels in intellectual disability, coupled with an overview of the physiological role of neuronal I KNa currents.

Why are genetic polymorphisms related to severe mental disorders retained in the gene pool of a population? A possible answer is that these genetic variations may have a positive impact on psychological functions. Here, I show that a biologically relevant polymorphism of the promoter region of the neuregulin 1 gene (SNP8NRG243177/rs6994992) is associated with creativity in people with high intellectual and academic performance. Intriguingly, the highest creative achievements and creative-thinking scores were found in people who carried the T/T genotype, which was previously shown to be related to psychosis risk and altered prefrontal activation.

Purpose of review The study summarizes supportive epidemiological data regarding the true co-occurrence (comorbidity) and course of mental disorders in children with intellectual disability/intellectual developmental disorders (ID/IDD) across the lifespan. Recent findings Published studies involving representative populations of children and adolescents with ID/IDD have demonstrated a three to four-fold increase in prevalence of co-occurring mental disorders. The effect of age, sex, and severity (mild, moderate, severe, and profound) and socioeconomic status on prevalence is currently not clearly understood. To date there are no prevalence estimates of co-occurring mental disorders in youth identified using the new DSM-5 (and proposed ICD-11) definition of ID/IDD using measures of intellectual functions and deficits in adaptive functioning with various severity levels defined on the basis of adaptive functioning, and not intellectual quotient scores. Summary The true relationship between two forms of morbidity remains complex and causal relationships that may be true for one disorder may not apply to another. The new conceptualization of ID/IDD offers a developmentally better informed psychobiological approach that can help distinguish co-occurrence of mental disorders within the neurodevelopmental section with onset during the developmental period as well as the later onset of other mental disorders.

Impaired cognitive functioning and poor quality of life (QoL) are both common among patients with end-stage liver disease; however, it is unclear how these are related. This study examines how specific cognitive domains predict QoL among liver transplant candidates by replicating Stewart and colleagues' (2010) 3-factor model of cognitive functioning, and determining how variability in these cognitive domains predicts mental health and physical QoL. The sample included 246 patients with end-stage liver disease who were candidates for liver transplant at a large, Midwestern health care center. Measures, including the Repeatable Battery for the Assessment of Neuropsychological Status, Trail Making Test, Shipley Institute of Living Scale, Short-Form Health Survey-36 Version 2, and Hospital Anxiety and Depression Scale, comprised latent variables representing global intellectual functioning, psychomotor speed, and learning and memory functioning. Confirmatory factor analysis results indicate that the 3-factor solution model comprised of global intellectual functioning, psychomotor speed, and learning and memory functioning fit the data well. Addition of physical and mental health QoL latent factors resulted in a structural model also with good fit. Results related physical QoL to global intellectual functioning, and mental health QoL to global intellectual functioning and psychomotor functioning. Findings elucidate a relationship between cognition and QoL and support the use of routine neuropsychological screening with end-stage liver disease patients, specifically examining the cognitive domains of global intellectual, psychomotor, and learning and memory functioning. Subsequently, screening results may inform implementation of targeted interventions to improve QoL. Copyright © 2016 The Academy of Psychosomatic Medicine. Published by Elsevier Inc.

Attention skills and executive functioning in children with Noonan syndrome and their unaffected siblings.

PubMed

Pierpont, Elizabeth I; Tworog-Dube, Erica; Roberts, Amy E

2015-04-01

Emerging research indicates that gene mutations within the RAS-MAPK signaling cascade, which cause Noonan syndrome and related disorders, affect neurophysiologic activity in brain regions underlying attention and executive functions. The present study examined whether children with Noonan syndrome are at heightened risk for symptoms of attention-deficit-hyperactivity disorder (ADHD) and executive dysfunction relative to an unaffected sibling comparison group, and investigated three key aspects of behavioral attention: auditory attention, sustained attention, and response inhibition. Children and adolescents with Noonan syndrome (n=32, 17 males, 15 females, mean age 11y 3mo, SD 3y) and their unaffected siblings (n=16, eight males, eight females, mean age 11y, SD 3y 6mo) were administered standardized tests of intellectual functioning and clinic-based measures of behavioral attention. Parent ratings of ADHD symptoms, executive functioning, and behavior were also obtained. Children with Noonan syndrome demonstrated higher rates of past ADHD diagnosis, as well as reduced performance compared with unaffected siblings on behavioral attention measures. Parent-rated functional impairments in attention, social skills, working memory, and self-monitoring were more prevalent in the Noonan syndrome group. The relationship between attention regulation skills (sustained attention and inhibitory control) and intellectual test performance was significantly stronger in the Noonan syndrome group than the comparison group. Clinical screening/evaluation for ADHD and executive dysfunction in Noonan syndrome is recommended to facilitate appropriate intervention and to address functional impact on daily life activities. © 2014 Mac Keith Press.

2018-02-01

The aim of our prospective observational study was to assess profiles of cognitive function and a possible impairment of executive functions in a cohort of boys with Duchenne muscular dystrophy without intellectual and behavior disability. Forty Duchenne boys (range of age: 6 years to 11 years and 6 months) were assessed by Wechsler Intelligence scale and battery of tests including tasks assessing working memory and executive functions (inhibition and switching, problem solving and planning). In our cohort some aspects of cognitive function were often impaired. These included multitasking, problem solving, inhibition and working memory necessary to plan and direct goal oriented behavior. Our results support the suggestion that aspects of cognitive function could be impaired even in boys without intellectual disability and support the hypothesis that executive functions may play an important role in specific aspects of cognitive impairment in Duchenne muscular dystrophy.

PTEN hamartoma tumour syndrome (PHTS) is caused by heterozygous variants in PTEN and is characterised by tumour predisposition, macrocephaly, and cognition impairment. Bi-allelic loss of PTEN activity has not been reported so far and animal models suggest that bi-allelic loss of PTEN activity is embryonically lethal. Here, we report the identification of a novel homozygous variant in PTEN, NM_000314.4; c.545T>C; p.Leu182Ser, in two adolescent siblings with severe macrocephaly and mild intellectual disability. The variant is predicted to be damaging and is associated with significantly increased phospho-S6 downstream of PTEN. The absence of tumours in the two homozygous siblings as well as lack of symptoms of PHTS in the heterozygous carriers of the family suggest that this particular variant is functionally hypomorphic rather than deleterious.

Cortical surface area has tremendously expanded during human evolution, and similar patterns of cortical expansion have been observed during childhood development. An intriguing hypothesis is that the high-expanding cortical regions also show the strongest correlations with intellectual function in humans. However, we do not know how the regional distribution of correlations between intellectual function and cortical area maps onto expansion in development and evolution. Here, in a sample of 1048 participants, we show that regions in which cortical area correlates with visuospatial reasoning abilities are generally high expanding in both development and evolution. Several regions in the frontal cortex, especially the anterior cingulate, showed high expansion in both development and evolution. The area of these regions was related to intellectual functions in humans. Low-expanding areas were not related to cognitive scores. These findings suggest that cortical regions involved in higher intellectual functions have expanded the most during development and evolution. The radial unit hypothesis provides a common framework for interpretation of the findings in the context of evolution and prenatal development, while additional cellular mechanisms, such as synaptogenesis, gliogenesis, dendritic arborization, and intracortical myelination, likely impact area expansion in later childhood. © The Author 2013.

2015-11-01

Important work has been carried out adapting cognitive behavioural therapy for people with intellectual disabilities. However, there is a lack of alternative psychological therapies available for people with intellectual disabilities and emotional difficulties. Behavioural activation for depression is less reliant on verbal communication and focuses on increasing purposeful activity and reducing avoidance. This feasibility study involved the development and piloting of an adapted manual of behavioural activation for people with intellectual disabilities. The intervention consisted of 10-12 sessions and a key adaptation was that the therapist worked with the clients alongside a significant other in their life, either a paid carer or family member. Baseline, post-intervention (3 months after entering the study) and 6-month quantitative follow-up data were obtained. Primary outcome data were gathered, concerning depressive symptoms, participants' levels of activity and general well-being. Twenty-three adults with intellectual disabilities with symptoms of depression were recruited from specialist health services. In terms of acceptability, the behavioural activation intervention was well received and only two individuals dropped out, with a further two lost to follow-up. The main measures of depression appeared to be sensitive to change. Pre- to post-intervention data showed a significant reduction in self-report of depressive symptoms with a strong effect size (r = 0.78), that was maintained at follow-up (r = 0.86). Positive change was also obtained for informant reports of depressive symptoms from pre- to post-intervention, with a strong effect size (r = 0.7). Once again, this positive change was maintained at follow-up (r = 0.72). The study suggested that behavioural activation may be a feasible and worthwhile approach to tackling depression in people with intellectual disabilities. However, a randomised controlled trial would be required to establish its effectiveness, with more sensitive measurement of change in activity. © 2014 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

2007-02-01

We conducted an online statewide survey of teachers of students with moderate and severe intellectual disabilities to determine the extent to which their students were included in school extracurricular and community recreation activities. For the 252 teacher respondents who indicated that their primary caseload consisted of students with significant intellectual disabilities, we report the numbers of students participating in school and community activities and the primary type of support students required to participate in each activity. Finally, we identify implications for practitioners who want to increase the participation of students with significant disabilities in school and community activities.

Physical activity interventions and children's mental function: An introduction and overview

Tomporowski, Phillip D.; Lambourne, Kate; Okumura, Michelle S.

2011-01-01

Background This review provides a historical overview of physical activity interventions designed by American educators and an evaluation of research that has assessed the effects of exercise on children's mental function. Method Historical descriptions of the emergence of American physical education doctrine throughout the 20th century were evaluated. Prior reviews of studies that assessed the effects of single acute bouts of exercise and the effects of chronic exercise training on children's mental function were examined and the results of recent studies were summarized. Results Physical activity interventions designed for American children have reflected two competing views: activities should promote physical fitness and activities should promote social, emotional, and intellectual development. Research results indicate that exercise fosters the emergence of children's mental function; particularly executive functioning. The route by which physical activity impacts mental functioning is complex and is likely moderated by several variables, including physical fitness level, health status, and numerous psycho-social factors. Conclusion Physical activity interventions for children should be designed to meet multiple objectives; e.g., optimize physical fitness, promote health-related behaviors that offset obesity, and facilitate mental development.

Cognitive functioning affects health. This study assessed cognitive functioning among participants in the Northwestern Juvenile Project, a stratified random sample of 1,829 newly detained juveniles (10 to 18 years old) from Cook County, Illinois. The study examined receptive vocabulary, oral reading, arithmetic computation skills, and general intellectual abilities. The sample exhibited impaired overall intellectual functioning and deficits in all areas. Males performed more poorly than females. More than three quarters of males showed below average overall intellectual functioning, and 9 in 10 had below average receptive vocabulary skills. Hispanic and African American males performed more poorly than non-Hispanic White males. The multiple systems that serve delinquent youth--correctional, health, legal, and rehabilitative--must collaborate to tailor needed services to the cognitive level of youth in the juvenile justice system.

Leisure activities, friendships, and quality of life of persons with intellectual disability: foster homes vs community residential settings.

PubMed

Duvdevany, Ilana; Arar, Efrat

2004-12-01

Living in the community does not, in itself, guarantee social integration and inclusion for persons with intellectual disability. Friendships and leisure participation can indicate the beginning of such a process and their impact on quality of life. The present study investigated the quality of life, friendships and leisure activities of persons with intellectual disability who live in community settings or in foster families. Three hypotheses were examined: 1. Persons with intellectual disability who live in foster families have more friends than do those who live in community residential settings. 2. Persons with intellectual disability who live in community residential settings participate in more leisure activities than those who live in foster families. 3. The more friendships and leisure activities in which one is involved, the higher the quality of one's life. The sample consisted of 85 adults with intellectual disability, ranging in age from 18 to 55 years. Forty-five live in community residential settings and 40 live in foster families in Israel. Five questionnaires were used: 1) a demographic questionnaire; 2) Quality of Life Questionnaire, 1990); 3) the Revised UCLA Loneliness Scale; 4) Social Relationships List; and 5) Leisure Activities List. The main findings show no significant differences between the two groups in the number of friendships or feelings of loneliness. Foster residents were more involved and more independent in their leisure activities than were those who live in community residences. An association between friendships, leisure activities and quality of life was partly confirmed. The need for intervention programs and leisure education programs is discussed.

[Psychoeducational intervention in high ability: intellectual functioning and extracurricular enrichment].

PubMed

Sastre-Riba, Sylvia

2014-02-24

The 'new paradigm' defines the high intellectual ability as a potential that should crystallize progressively throughout development. Its main feature is a high intellectual initial multidimensional potential, which is transformed so that, being a person with high intellectual ability is the result of a developmental process from a neurobiological substrate and the incidence of variables (psychosocial and education) which determines its manifestation more or less stable and optimal to excellence. It is interesting to know the effectiveness of psychoeducational intervention of the extracurricular enrichment programs and their effects on the expression of differential functioning and the optimization of the management of cognitive resources that lead to excellence. An extracurricular enrichment program is described and evaluated through: 1) the stability of the intellectual measures; 2) the satisfaction level of participants and families. Participants are 58 high ability students on the enrichment program and 25 parents. Intellectual profiles are obtained on T1-T2 and calculated their stability by regression analysis, the CSA and CSA-P questionnaires were applied in order to know the participants and families' satisfaction measure. Results show the basic stability of intellectual profiles with five cases of instability among the 58 profiles obtained, and a high satisfaction with the results obtained in the domain of cognitive and personal management among the participants.

The aim of this study was to assess the influence of sex, age, level and etiology of intellectual disability on visual-motor integration in children with intellectual disability. The sample consisted of 90 children with intellectual disability between 7 and15 years of age. Visual-motor integration was measured using the Acadia test of visual-motor integration. A multiple regression analysis was used for data analysis. The results of this study showed that sex, level of intellectual disability, and age were significant predictors of visual-motor integration. The etiology of intellectual disability did not play a significant role in predicting visual-motor integration. Visual-motor integration skills are very important for a child's overall level of functioning. Individualized programs for the remediation of visual-motor integration skills should be a part of the curriculum for children with intellectual disability.

The drug burden index (DBI) is a dose-related measure of anticholinergic and sedative drug exposure. This cross-sectional study described DBI in older adults with intellectual disabilities (ID) and the most frequently reported therapeutic classes contributing to DBI and examined associations between higher DBI scores and potential adverse effects as well as physical function. This study analysed data from Wave 2 (2013/2014) of the Intellectual Disability Supplement to the Irish Longitudinal Study on Ageing (IDS-TILDA), a representative study on the ageing of people with ID in Ireland. Self- and objectively-reported data were collected on medication use and physical health, including health conditions. The Barthel index was the physical function measure. The study examined 677 individuals with ID, of whom 644 (95.1%) reported taking medication and 78.6% (n = 532) were exposed to medication with anticholinergic and/or sedative activity. 54.2% (n = 367) were exposed to high DBI score (≥1). Adjusted multivariate regression analysis revealed no significant association between DBI score and daytime dozing, constipation or falls. After adjusting for confounders (sex, age, level of ID, comorbidities, behaviours that challenge, history of falls), DBI was associated with significantly higher dependence in the Barthel index (P = 0.002). This is the first time DBI has been described in older adults with ID. Scores were much higher than those observed in the general population and higher scores were associated with higher dependence in Barthel index activities of daily living. © 2017 The British Pharmacological Society.

Brooker, Katie; van Dooren, Kate; McPherson, Lyn; Lennox, Nick; Ware, Robert

Evidence suggests that most adults with intellectual disability do not participate in sufficient amounts of physical activity (PA). A systematic review of peer-reviewed studies that reported an intervention aiming to improve PA levels of adults with intellectual disability was conducted. Keywords related to intellectual disability and physical activity were used to search relevant databases. Studies were excluded if they did not measure PA as an outcome for adults with intellectual disability, were non-English, and were not peer-reviewed. All relevant studies were included in the review regardless of methodological quality and design. Six articles met the inclusion criteria. These included health education or health promotion programs with PA, nutrition, and weight loss components. The quality of studies included in this review was generally poor. Most studies used a prepost design, sample sizes were small, and measurement tools were used that are not valid and reliable for the population assessed. PA interventions have the potential to improve the health and wellbeing of people with intellectual disability, a vulnerable group who require attention from public health practitioners and researchers. Given the health inequities that exist, public health researchers should target efforts to improve PA levels among this group.

Social Cognition in Williams Syndrome: Relations between Performance on the Social Attribution Task and Cognitive and Behavioral Characteristics.

Williams syndrome (WS) is a developmental disorder of genetic origin, with characteristic cognitive and personality profiles. Studies of WS point to an outgoing and gregarious personality style, often contrasted with autism spectrum disorders; however, recent research has uncovered underlying social reciprocity difficulties in people with WS. Social information processing difficulties that underlie these social reciprocity difficulties have been sparsely examined. Participants in the current study included 24 children with WS ages 8 through 15. A lab-based measure of social perception and social cognition was administered (Social Attribution Test), as well as an intellectual functioning measure (KBIT-II) and parent reports of communication and reciprocal social skills (Social Communication Questionnaire, Social Responsiveness Scale). Relations between social cognition, cognitive abilities, and social-communication were examined. Results demonstrated relations between parent-reported social reciprocity and the typicality of the responses provided in the lab-based measure, even once variability in intellectual functioning was taken into account. Specifically, those individuals who produced narratives in response to the social attribution task (SAT) that were more similar to those described in previous studies of typically developing individuals were also reported to have fewer social reciprocity difficulties in the real world setting as reported by parents. In addition, a significant improvement in performance on the SAT was seen with added scaffolding, particularly for participants with stronger intellectual functioning. These findings indicate that difficulties interpreting the social dynamics between others in ambiguous situations may contribute to the social relationship difficulties observed in people with WS, above and beyond the role of intellectual functioning. Exploratory analyses indicated that performance by individuals with stronger intellectual functioning is improved with additional structure to a greater degree than for those with weaker intellectual functioning. Interventions that specifically target these social information processing of individuals with WS would likely be beneficial.

Is intelligence equivalent to executive functions?

PubMed

Ardila, Alfredo

2018-05-01

Since the mid 19th century, cognitive and behavioral neurosciences have attempted to find the neurological bases of intellectual abilities. During the early 20th century the psychometric concept of "intelligence" was coined; and toward the end of the 20th century the neuropsychological concept of "executive functions" was introduced. Controversies, however, remain about the unity or heterogeneity of so-called executive functions. It is proposed that two major executive functions could be separated: metacognitive -or intelectual- and emotional/motivational. A similar distinction has been suggested by several authors. Standard definitions of intelligence implicitly assume that executive functions represent the fundamental components of intelligence. Research has demonstrated that, if considered as a whole, executive functions only partially correspond to the psychometric concept of intelligence; whereas some specific executive functions clearly correspond to intelligence, some others do not involve intelligence. If using a major distinction between metacognitive -or simply "intellectual"-executive functions, and emotional/ motivational -or simply non-intellectual-executive functions, it becomes evident that general intelligence can be equated with metacognitive executive functions but not with emotional/ motivational executive functions.

NDST1 was recently proposed as a candidate gene for autosomal recessive intellectual disability in two families. It encodes a bifunctional GlcNAc N-deacetylase/N-sulfotransferase with important functions in heparan sulfate biosynthesis. In mice, Ndst1 is crucial for embryonic development and homozygous null mutations are perinatally lethal. We now report on two additional unrelated families with homozygous missense NDST1 mutations. All mutations described to date predict the substitution of conserved amino acids in the sulfotransferase domain, and mutation modeling predicts drastic alterations in the local protein conformation. Comparing the four families, we noticed significant overlap in the clinical features, including both demonstrated and apparent intellectual disability, muscular hypotonia, epilepsy, and postnatal growth deficiency. Furthermore, in Drosophila, knockdown of sulfateless, the NDST ortholog, impairs long-term memory, highlighting its function in cognition. Our data confirm NDST1 mutations as a cause of autosomal recessive intellectual disability with a distinctive phenotype, and support an important function of NDST1 in human development. © 2014 Wiley Periodicals, Inc.

Memisevic, Haris; Sinanovic, Osman

2013-12-01

The goal of this study was to assess the relationship between visual-motor integration and executive functions, and in particular, the extent to which executive functions can predict visual-motor integration skills in children with intellectual disability. The sample consisted of 90 children (54 boys, 36 girls; M age = 11.3 yr., SD = 2.7, range 7-15) with intellectual disabilities of various etiologies. The measure of executive functions were 8 subscales of the Behavioral Rating Inventory of Executive Function (BRIEF) consisting of Inhibition, Shifting, Emotional Control, Initiating, Working memory, Planning, Organization of material, and Monitoring. Visual-motor integration was measured with the Acadia test of visual-motor integration (VMI). Regression analysis revealed that BRIEF subscales explained 38% of the variance in VMI scores. Of all the BRIEF subscales, only two were statistically significant predictors of visual-motor integration: Working memory and Monitoring. Possible implications of this finding are further elaborated.

2010-01-01

Individuals with intellectual and developmental disabilities often have difficulties foregoing short-term loss for long-term gain. The Iowa Gambling Task (IGT) has been extensively adopted as a laboratory measure of this ability. In the present study, we undertook the first investigation with people with intellectual disabilities using a two-choice child version of the IGT, with measures of intellectual and executive functioning. Compared to a group of matched controls, people with intellectual disabilities performed advantageously and showed high levels of subjective awareness about the relative goodness and badness of the decks. A symbol labelling intervention, in which participants were taught to label the good and bad decks at regular intervals significantly improved advantageous decision-making to levels approximating that of controls. Factor analysis of executive functioning scores identified working memory and mental flexibility (response initiation and set shifting), with a near-significant inverse correlation between the extent to which the intervention was required and mental flexibility. These findings show, for the first time, that people with intellectual disabilities are capable of performing advantageously on the IGT and add to the growing clinical literature on decision-making.

2017-01-01

By searching a clinical database of over 60,000 individuals referred for array-based CNV analyses and online resources, we identified four males from three families with intellectual disability, developmental delay, hypotonia, joint hypermobility and relative macrocephaly who carried small, overlapping deletions of Xp11.22. The maximum region of overlap between their deletions spanned ~430 kb and included two pseudogenes, CENPVL1 and CENPVL2, whose functions are not known, and two protein coding genes-the G1 to S phase transition 2 gene (GSPT2) and the MAGE family member D1 gene (MAGED1). Deletions of this ~430 kb region have not been previously implicated in human disease. Duplications of GSPT2 have been documented in individuals with intellectual disability, but the phenotypic consequences of a loss of GSPT2 function have not been elucidated in humans or mouse models. Changes in MAGED1 have not been associated with intellectual disability in humans, but loss of MAGED1 function is associated with neurocognitive and neurobehavioral phenotypes in mice. In all cases, the Xp11.22 deletion was inherited from an unaffected mother. Studies performed on DNA from one of these mothers did not show evidence of skewed X-inactivation. These results suggest that deletions of an ~430 kb region on chromosome Xp11.22 that encompass CENPVL1, CENPVL2, GSPT2 and MAGED1 cause a distinct X-linked syndrome characterized by intellectual disability, developmental delay, hypotonia, joint hypermobility and relative macrocephaly. Loss of GSPT2 and/or MAGED1 function may contribute to the intellectual disability and developmental delay seen in males with these deletions.

Evaluation of a group based cognitive behavioural therapy programme for menstrual pain management in young women with intellectual disabilities: protocol for a mixed methods controlled clinical trial

PubMed Central

2014-01-01

Background Menstrual pain which is severe enough to impact on daily activities is very common amongst menstruating females. Research suggests that menstrual pain which impacts on daily functioning may be even more prevalent amongst those with intellectual disabilities. Despite this, little research attention has focused on pain management programmes for those with intellectual disabilities. The aims of this pilot study were to develop and evaluate a theory-based cognitive behavioural therapy (CBT) programme for menstrual pain management in young women with intellectual disabilities. Methods/Design The study utilised a mixed methods controlled clinical trial to evaluate elements from a CBT programme called Feeling Better (McGuire & McManus, 2010). The Feeling Better programme is a modular, manualised intervention designed for people with an intellectual disability and their carers. The programme was delivered to 36 young women aged 12 – 30 years who have a Mild - Moderate Intellectual Disability, split between two conditions. The treatment group received the Feeling Better intervention and the control group received treatment as usual. To evaluate the effectiveness of the programme, measures were taken of key pain variables including impact, knowledge, self-efficacy and coping. Process evaluation was conducted to examine which elements of the programme were most successful in promoting change. Discussion Participants in the intervention group were expected to report the use of a greater number of coping strategies and have greater knowledge of pain management strategies following participation in the intervention and at three month follow-up, when compared to control group participants. A significant advantage of the study was the use of mixed methods and inclusion of process evaluation to determine which elements of a cognitive behavioural therapy programme work best for individuals with intellectual disabilities.

2017-01-01

AMPA-type glutamate receptors (AMPARs), key elements in excitatory neurotransmission in the brain, are macromolecular complexes whose properties and cellular functions are determined by the co-assembled constituents of their proteome. Here we identify AMPAR complexes that transiently form in the endoplasmic reticulum (ER) and lack the core-subunits typical for AMPARs in the plasma membrane. Central components of these ER AMPARs are the proteome constituents FRRS1l (C9orf4) and CPT1c that specifically and cooperatively bind to the pore-forming GluA1-4 proteins of AMPARs. Bi-allelic mutations in the human FRRS1L gene are shown to cause severe intellectual disability with cognitive impairment, speech delay and epileptic activity. Virus-directed deletion or overexpression of FRRS1l strongly impact synaptic transmission in adult rat brain by decreasing or increasing the number of AMPARs in synapses and extra-synaptic sites. Our results provide insight into the early biogenesis of AMPARs and demonstrate its pronounced impact on synaptic transmission and brain function. PMID:28675162

Synaptic target specificity, whereby neurons make distinct types of synapses with different target cells, is critical for brain function, yet the mechanisms driving it are poorly understood. In this study, we demonstrate Kirrel3 regulates target-specific synapse formation at hippocampal mossy fiber (MF) synapses, which connect dentate granule (DG) neurons to both CA3 and GABAergic neurons. Here, we show Kirrel3 is required for formation of MF filopodia; the structures that give rise to DG-GABA synapses and that regulate feed-forward inhibition of CA3 neurons. Consequently, loss of Kirrel3 robustly increases CA3 neuron activity in developing mice. Alterations in the Kirrel3 gene are repeatedly associated with intellectual disabilities, but the role of Kirrel3 at synapses remained largely unknown. Our findings demonstrate that subtle synaptic changes during development impact circuit function and provide the first insight toward understanding the cellular basis of Kirrel3-dependent neurodevelopmental disorders.

Community Involvement of Young Adults with Intellectual Disabilities: Their Experiences and Perspectives on Inclusion.

PubMed

Hall, Sarah A

2017-09-01

Inclusion in the community is essential to enhancing a person's quality of life. Although people with intellectual disabilities have a desire to be more involved in activities, they experience barriers that limit their inclusion. The purpose of this study was to describe the community involvement of young adults with intellectual disability. I interviewed fourteen young adults with intellectual disability to explore their involvement in work, recreation and leisure activities. Four themes emerged from the data: vocational endeavours, leisure pursuits, social inclusion and supports. The contexts of their experiences either facilitated or hindered their community involvement. The community involvement of young adults with intellectual disability varies depending on the opportunities and supports available to them. Their inclusion in the community may be enhanced by additional transportation options, continuing education in vocational and social skills, personalized guidance from group members and environments that are welcoming to people with disabilities. © 2016 John Wiley & Sons Ltd.

Lewis Carroll: a study of mathematical inhibition.

PubMed

Keller, E F

1980-01-01

Carroll's mathematical abilities appear to have been severely constrained--subject simultaneously to inhibition and distortion. Through an analysis of his informal commentary on his relation to mathematical puzzles I have attempted to understand and explain the nature of these inhibitions and distortions. Particular attention to his metaphor of the "mental bun," and his use of this metaphor, has led me to conclude that the mathematical puzzle served, for Carroll, distinctly fetishistic functions. This interpretation dovetails with Greenacre's early intuition about the prevalence in his literary work of fantasies and preoccupations reminescent of clinical experience with fetishism. The connection argued here between inhibitions and distortions in the sexual and intellectual realms suggests, as a domain for further inquiry, the possibility of a more general investigation into the role of sexual fantasies in intellectual activities.

2018-01-01

The prevalence of obesity is higher in those with intellectual disabilities than the general population. The aim of the study was to understand the determinants of physical activity and dietary patterns in this population during their final year of school. Qualitative data were generated from 10 interviews with adolescents with mild-moderate intellectual disabilities. Data were analysed using deductive thematic analysis, employing Self-Determination Theory as a theoretical framework. Adolescents' environment and social interactions play a pivotal role in influencing physical activity and dietary patterns. Three themes emerged from the analysis: situatedness, motivation and wider environmental influences. School structure, high self-efficacy and social connectedness facilitate increased physical activity and healthier diet in adolescents with intellectual disabilities. Home life, low self-efficacy and a lack of social connectedness can serve as a barrier to PA and a healthy diet. © 2017 John Wiley & Sons Ltd.

Looking beyond maternal sensitivity: mother-child correlates of attachment security among children with intellectual disabilities in urban India.

PubMed

John, Aesha; Morris, Amanda Sheffield; Halliburton, Amy L

2012-11-01

This study examined correlates of attachment security among children with intellectual disabilities in urban India. Survey and observational data were gathered from 47 children, mothers, and teachers on children's attachment security, adaptive functioning, and mother-child emotional availability. The data were analyzed to examine whether child emotional availability mediates the links between maternal emotional availability and child attachment security, and between child functioning and attachment security. The results supported full mediation, indicating that children's emotional availability was a primary mechanism through which maternal emotional availability and child functioning were linked to attachment security among children in our sample. The study findings are discussed in the context of implications for family interventions and research on socio-emotional development among children with intellectual disabilities.

It is time to bring borderline intellectual functioning back into the main fold of classification systems

PubMed Central

Wieland, Jannelien; Zitman, Frans G.

2016-01-01

Borderline intellectual functioning is an important and frequently unrecognised comorbid condition relevant to the diagnosis and treatment of any and all psychiatric disorders. In the DSM-IV-TR, it is defined by IQ in the 71–84 range. In DSM-5, IQ boundaries are no longer part of the classification, leaving the concept without a clear definition. This modification is one of the least highlighted changes in DSM-5. In this article we describe the history of the classification of borderline intellectual functioning. We provide information about it and on the importance of placing it in the right context and in the right place in future DSM editions and other classification systems such as the International Classification of Diseases.

2017-05-01

Adapted parenting support may alleviate the high levels of parenting stress experienced by many parents with intellectual disabilities. Parents with mild intellectual disabilities or borderline intellectual functioning were randomized to experimental (n = 43) and control (n = 42) conditions. Parents in both groups received care-as-usual. The experimental group also received an adapted version of video-feedback intervention for positive parenting and learning difficulties (VIPP-LD). Measures of parenting stress were obtained pre-test, post-test and 3-month follow-up. Randomization to the experimental group led to a steeper decline in parenting stress related to the child compared to the control group (d = 0.46). No statistically significant effect on stress related to the parent's own functioning or situation was found. The results of the study suggest the feasibility of reducing parenting stress in parents with mild intellectual disability (MID) through parenting support, to the possible benefit of their children. © 2016 John Wiley & Sons Ltd.

The role of the external personal assistants for children with profound intellectual and multiple disabilities working in the children's home.

PubMed

Axelsson, Anna Karin

2015-05-01

Children with profound intellectual and multiple disabilities need support to function in an optimal way. However, there is a limited knowledge about the role of external personal assistants working in the children's home. A mixed method study was performed including qualitative data from interviews with 11 Swedish parents and nine external personal assistants and quantitative data from questionnaires answered by 60 families. For the child, the assistant's role was one of reinforcing, meaning supportive and empowering, and the child needed a high level of assistance. For the family, the role was one of balancing and the external personal assistant was more often found to assist in activities away from home while parents tended to assist within home and in family unit activities. In planning and implementation of external assistance, the child's needs as well as considerations of the whole family should be regarded. © 2014 John Wiley & Sons Ltd.

Reconsidering reflexivity: introducing the case for intellectual entrepreneurship.

PubMed

Cutcliffe, John R

2003-01-01

In this article, the author reconsiders reflexivity and attempts to examine some unresolved issues by drawing particular attention to the relationship between reflexivity and certain related phenomena/processes: the researcher's a priori knowledge, values, beliefs; empathy within qualitative research; the presence and influence of the researcher's tacit knowledge, and May's "magic" in method. Given the limitations of some reflexive activity identified in this article, the author introduces the case for greater intellectual entrepreneurship within the context of qualitative research. He suggests that excessive emphasis on reflexive activity might inhibit intellectual entrepreneurship. Wherein intellectual entrepreneurship implies a conscious and deliberate attempt on the part of academics to explore the world of ideas boldly; to take more risks in theory development and to move away from being timid researchers.

Engagement in family activities: a quantitative, comparative study of children with profound intellectual and multiple disabilities and children with typical development.

PubMed

Axelsson, A K; Granlund, M; Wilder, J

2013-07-01

Participation is known to be of great importance for children's development and emotional well-being as well as for their families. In the International Classification of Functioning, Disability and Health - Children and Youth version participation is defined as a person's 'involvement in a life situation'. Engagement is closely related to involvement and can be seen as expressions of involvement or degree of involvement within a situation. This study focuses on children's engagement in family activities; one group of families with a child with profound intellectual and multiple disabilities (PIMD) and one group of families with children with typical development (TD) were compared. A descriptive study using questionnaires. Analyses were mainly performed by using Mann-Whitney U-test and Spearman's rank correlation test. Engagement in family activities differed in the two groups of children. The children with PIMD had a lower level of engagement in most family activities even though the activities that engaged the children to a higher or lesser extent were the same in both groups. Child engagement was found to correlate with family characteristics mostly in the children with TD and in the children with PIMD only negative correlations occurred. In the children with PIMD child engagement correlated with cognition in a high number of listed family activities and the children had a low engagement in routines in spite of these being frequently occurring activities. Level of engagement in family activities in the group of children with PIMD was lower compared with that in the group of children with TD. Families with a child with PIMD spend much time and effort to adapt family living patterns to the child's functioning. © 2013 John Wiley & Sons Ltd.

2018-05-30

Associations between late-life participation in intellectual activities and decreased odds of developing dementia have been reported. However, reverse causality and confounding effects due to other health behaviors or problems have not been adequately addressed. To examine whether late-life participation in intellectual activities is associated with a lower risk of incident dementia years later, independent of other lifestyle and health-related factors. A longitudinal observational study was conducted at all Elderly Health Centres of the Department of Health of the Government of Hong Kong among 15 582 community-living Chinese individuals age 65 years or older at baseline who were free of dementia, with baseline evaluations performed January 1 to June 30, 2005, and follow-up assessments performed from January 1, 2006, to December 31, 2012. Statistical analysis was performed from January 1, 2015, to December 31, 2016. The main outcome was incident dementia as diagnosed by geriatric psychiatrists in accordance with the International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, or a Clinical Dementia Rating of 1 to 3. At baseline and follow-up interviews, self-reported information on participation in intellectual activities within 1 month before assessment was collected. Examples of intellectual activities, which were described by a local validated classification system, were reading books, newspapers, or magazines; playing board games, Mahjong, or card games; and betting on horse racing. Other important variables including demographics (age, sex, and educational level), physical and psychiatric comorbidities (cardiovascular risks, depression, visual and hearing impairments, and poor mobility), and lifestyle factors (physical exercise, adequate fruit and vegetable intake, smoking, and recreational and social activities) were also assessed. Of the 15 582 individuals in the study, 9950 (63.9%) were women, and the median age at baseline was 74 years (interquartile range, 71-77 years). A total of 1349 individuals (8.7%) developed dementia during a median follow-up period of 5.0 years. Multivariable logistic regression analysis showed that the estimated odds ratio for incident dementia was 0.71 (95% CI, 0.60-0.84; P < .001) for those with intellectual activities at baseline, after excluding those who developed dementia within 3 years after baseline and adjusting for health behaviors, physical and psychiatric comorbidities, and sociodemographic factors. Active participation in intellectual activities, even in late life, might help delay or prevent dementia in older adults.

2014-06-01

To examine intellectual, behavioral, and emotional functioning of children who have syndromic craniosynostosis and to explore differences between diagnostic subgroups. A national sample of children who have syndromic craniosynostosis participated in this study. Intellectual, behavioral, and emotional outcomes were assessed by using standardized measures: Wechsler Intelligence Scale for Children, Third Edition, Child Behavior Checklist (CBCL)/6-18, Disruptive Behavior Disorder rating scale (DBD), and the National Institute of Mental Health Diagnostic Interview Schedule for Children. We included 82 children (39 boys) aged 6 to 13 years who have syndromic craniosynostosis. Mean Full-Scale IQ (FSIQ) was in the normal range (M = 96.6; SD = 21.6). However, children who have syndromic craniosynostosis had a 1.9 times higher risk for developing intellectual disability (FSIQ < 85) compared with the normative population (P < .001) and had more behavioral and emotional problems compared with the normative population, including higher scores on the CBCL/6-18, DBD Total Problems (P < .001), Internalizing (P < .01), social problems (P < .001), attention problems (P < .001), and the DBD Inattention (P < .001). Children who have Apert syndrome had lower FSIQs (M = 76.7; SD = 13.3) and children who have Muenke syndrome had more social problems (P < .01), attention problems (P < .05), and inattention problems (P < .01) than normative population and with other diagnostic subgroups. Although children who have syndromic craniosynostosis have FSIQs similar to the normative population, they are at increased risk for developing intellectual disability, internalizing, social, and attention problems. Higher levels of behavioral and emotional problems were related to lower levels of intellectual functioning.

A framework for the management of intellectual capital in the health care industry.

PubMed

Grantham, C E; Nichols, L D; Schonberner, M

1997-01-01

This article proposes a new theoretical model for the effective management of intellectual capital in the health care industry. The evolution of knowledge-based resources as a value-adding characteristic of service industries coupled with mounting environmental pressures on health care necessitates the extension of current models of intellectual capital. Our theoretical model contains an expanded context linking its development to organizational learning theory and extends current theory by proposing a six-term archetype of organizational functioning built on flows of information. Further, our proposal offers a hierarchical dimension to intellectual capital and a method of scientific visualization for the measurement of intellectual capital. In conclusion, we offer some practical suggestions for future development, both for researchers and managers.

Down syndrome--genetic and nutritional aspects of accompanying disorders.

PubMed

Mazurek, Dominika; Wyka, Joanna

2015-01-01

Down syndrome (DS) is one of the more commonly occurring genetic disorders, where mental retardation is combined with nutritional diseases. It is caused by having a third copy of chromosome 21, and there exist 3 forms; Simple Trisomy 21, Translocation Trisomy and Mosaic Trisomy. Symptoms include intellectual disability/mental retardation, early onset of Alzheimer's disease and the appearance of various phenotypic features such as narrow slanted eyes, flat nose and short stature. In addition, there are other health problems throughout the body, consisting in part of cardiac defects and thyroid function abnormalities along with nutritional disorders (ie. overweight, obesity, hypercholesterolemia and deficiencies of vitamins and minerals). Those suffering DS have widespread body frame abnormalities and impaired brain development and function; the latter leading to impaired intellectual development. Many studies indicate excessive or deficient nutrient uptakes associated with making inappropriate foodstuff choices, food intolerance, (eg. celiac disease) or malabsorption. DS persons with overweight or obesity are linked with a slow metabolic rate, abnormal blood leptin concentrations and exhibit low levels of physical activity. Vitamin B group deficiencies and abnormal blood homocysteine levels decrease the rate of intellectual development in DS cases. Zinc deficiencies result in short stature, thyroid function disorders and an increased appetite caused by excessive supplementation. Scientific advances in the research and diagnosis of DS, as well as preventing any associated conditions, have significantly increased life expectancies of those with this genetic disorder. Early dietary interventions by parents or guardians of DS children afford an opportunity for decreasing the risk or delaying some of the DS associated conditions from appearing, thus beneficially impacting on their quality of life.

Forensic issues in intellectual disability.

PubMed

Søndenaa, Erik; Rasmussen, Kirsten; Nøttestad, Jim Aage

2008-09-01

The present paper reviews some of the most significant findings in the field of forensic issues related to intellectual disability over the last 2 years. Recent publications have explored the prevalence and assessment of intellectual disabilities in the criminal justice system, as well as individual characteristics of intellectual disabled offenders. Service by the criminal justice system and treatment of intellectual disabled offenders have also been explored. New insights into violence and sexual offences have been achieved, however identification and evidence-based treatment of intellectual disabled offenders are not widely explored issues. Progress in treatment studies, studies of the function of the criminal justice system and risk assessments have resulted in improvements in these aspects during recent years. The wide range of services involved in successful initiatives has been addressed, but some crucial aspects still receive too little attention. Differences between countries and cultures have not been emphasized, and the progress that has been achieved seems to be confined to countries with a clear policy and organized services for offenders with intellectual disabilities.

2008-12-01

Epilepsy is the most common non-infectious neurologic disease in developing countries such as Africa, including Nigeria. This study was designed to assess the intellectual performance of patients with epilepsy (PWE) in Nigeria hoping that the result will serve as the basis for educational, vocational, and social counseling. Forty-one PWE were studied along with 41 age-, sex- and education-matched healthy controls. A questionnaire was developed and applied to all subjects and history was taken from patients and eyewitness. The intellectual function of each subject was assessed with the aid of Wechsler Adult Intelligence Scale adapted for Nigerians. All patients subsequently had electroencephalography (EEG) performed and the EEG findings were noted. SPSS statistical package was used to analyze the data. The PWE performed poorly on the verbal IQ, performance IQ, and full scale IQ scores when compared with controls (P < 0.05) and 20% of PWE had mental retardation. Long duration of epilepsy, long duration of antiepileptic drug therapy, younger age at onset of epilepsy, increased frequency of seizures, and low educational status were found to have negative impacts on intellectual performance in PWE (P < 0.05) while seizure types and type of antiepileptic drugs (carbamazepine or phenytoin) did not influence intellectual performance. This study shows that PWE had significant intellectual impairment when compared with controls. In addition, long duration of epilepsy, long duration of AED therapy, earlier age of onset, increased seizure frequency, and low educational status had a negative impact on intellectual functioning in PWE.

2008-01-01

This study tested a path model that included perceptions of social support and self-efficacy for leisure physical activity and leisure physical activity participation among adults with intellectual disabilities. A cross-sectional design was used. Data was collected via oral interview. Community-based group, supported-living settings in one Midwestern state. A total of 152 adults with mild to moderate intellectual disabilities, which provided a 39% response rate. Self-efficacy and social support (from family, residential staff and peers with disabilities) for leisure physical activity were assessed using self-reported scales. Leisure physical activity participation was measured with a self-reported checklist of the frequency of leisure physical activity participation. Path analysis was conducted for the entire sample and was repeated for younger and older age groups. The hypothesized model fit the data from each group. Social support and self-efficacy predicted physical activity participation, and self-efficacy served as a mediator between social support and physical activity. Significant sources of social support differed between groups; among younger participants, social support from family predicted physical activity, whereas, for the older group, social support from staff and peers predicted physical activity. Self-efficacy and social support for leisure physical activity are related to leisure physical activity participation among adults with intellectual disabilities who are receiving supported-living services. The results provide information to guide health promotion programs for this group.

As individuals with intellectual and developmental disabilities become more engaged in community employment, it will be critical to consider how their employment experience changes as they age. Similar to other seniors, individuals will need to consider whether they want to maintain their employment, reduce their work commitment, or retire completely. If they do choose to retire, what activities will they choose to engage in, and what service or supports might be necessary? This article considers the issues faced by all aging workers in regard to retirement planning and active aging as well as specific strategies for individuals with intellectual and developmental disabilities to remain active and engaged. Recommendations for service options, policy consideration, and future research are also discussed.

Heart transplantation in children with intellectual disability is a controversial issue. We sought to describe the prevalence and outcomes of heart transplantation in children with intellectual disability and hypothesized that recipients with intellectual disability have comparable short-term outcomes compared to recipients without intellectual disability. We performed a retrospective cohort analysis of children receiving a first heart-alone transplant in the UNOS STAR database from 2008 to 2013. Recipients with intellectual disability were compared to those without using chi-square tests. Kaplan-Meier curves were constructed for patient and graft survival. Cox proportional hazard models were used to estimate the association between intellectual disability and graft failure and patient survival. Over the study period, 107 children with intellectual disability underwent initial heart transplantation, accounting for 8.9% of first pediatric heart transplants (total=1204). There was no difference in the incidence of acute rejection between groups in the first year after transplant. Mean functional status scores at follow-up improved in both groups after transplantation, but tended to be lower among children with intellectual disability than children without. Log-rank tests did not suggest significant differences in graft survival between those with and without intellectual disability during the first 4 years following transplantation. Children with intellectual disability constitute a significant portion of total heart transplants with short-term outcomes comparable to children without intellectual disability. © 2016 John Wiley & Sons A/S.

2007-01-01

Background We recently reported results of a cross-sectional investigation of intellectual function in 10-year-olds in Bangladesh, who had been exposed to arsenic from drinking water in their home wells. Objectives We present results of a similar investigation of 301 randomly selected 6-year-olds whose parents participated in our ongoing prospective study of the health effects of As exposure in 12,000 residents of Araihazar, Bangladesh. Methods Water As and manganese concentrations of tube wells at each home were obtained by surveying all study region wells. Children and mothers were first visited at home, where the quality of home stimulation was measured, and then seen in our field clinic, where children received a medical examination wherein weight, height, and head circumference were assessed. We assessed children’s intellectual function using subtests drawn from the Wechsler Preschool and Primary Scale of Intelligence, version III, by summing weighted items across domains to create Verbal, Performance, Processing Speed, and Full-Scale raw scores. Children provided urine specimens for measuring urinary As and were asked to provide blood samples for blood lead measurements. Results Exposure to As from drinking water was associated with reduced intellectual function before and after adjusting for water Mn, for blood lead levels, and for sociodemographic features known to contribute to intellectual function. With covariate adjustment, water As remained significantly negatively associated with both Performance and Processing Speed raw scores; associations were less strong than in our previously studied 10-year-olds. Conclusion This second cross-sectional study of As exposure expands our concerns about As neurotoxicity to a younger age group. PMID:17384779

Family functioning in families with a child with Down syndrome: a mixed methods approach.

PubMed

Povee, K; Roberts, L; Bourke, J; Leonard, H

2012-10-01

This study aimed to explore the factors that predict functioning in families with a child with Down syndrome using a mixed methods design. The quantitative component examined the effect of maladaptive and autism-spectrum behaviours on the functioning of the family while the qualitative component explored the impact of having a child with Down syndrome on family holidays, family activities and general family functioning. Participants in this study were 224 primary caregivers of children with Down syndrome aged 4-25 years (57.1% male; 42.9% female) currently residing in Western Australia (74.0% in metropolitan Perth and 26.0% in rural Western Australia). Maladaptive and autism-spectrum behaviour were associated with poorer family functioning. Mean total scores on the measures of family functioning and marital adjustment were comparable to that of families of typically developing children. Consistent with the quantitative findings, normality was the most common theme to emerge in the qualitative data. Child problem behaviours were also identified by parents/carers as having a negative impact on the family. This study has implications for the development of programs to support families with a child with Down syndrome and may dispel some of the myths surrounding the impact of intellectual disability on the family. © 2012 The Authors.

Physical fitness is predictive for a decline in daily functioning in older adults with intellectual disabilities: results of the HA-ID study.

PubMed

Oppewal, Alyt; Hilgenkamp, Thessa I M; van Wijck, Ruud; Schoufour, Josje D; Evenhuis, Heleen M

2014-10-01

A high incidence of limitations in daily functioning is seen in older adults with intellectual disabilities (ID), along with poor physical fitness levels. The aim of this study was to assess the predictive value of physical fitness for daily functioning after 3 years, in 602 older adults with borderline to profound ID (≥ 50 years). At baseline, physical fitness levels and daily functioning (operationalized as basic activities of daily living [ADL] and mobility) were assessed. After 3 years, the measurements of daily functioning were repeated. At follow-up, 12.6% of the participants were completely independent in ADL and 48.5% had no mobility limitations. More than half of the participants (54.8%) declined in their ability to perform ADL and 37.5% declined in their mobility. Manual dexterity, visual reaction time, balance, comfortable and fast gait speed, muscular endurance, and cardiorespiratory fitness were significant predictors for a decline in ADL. For a decline in mobility, manual dexterity, balance, comfortable and fast walking speed, grip strength, muscular endurance, and cardiorespiratory fitness were all significant predictors. This proves the predictive validity of these physical fitness tests for daily functioning and stresses the importance of using physical fitness tests and implementing physical fitness enhancing programs in the care for older adults with ID.

Executive function in children with intellectual disability--the effects of sex, level and aetiology of intellectual disability.

PubMed

Memisevic, H; Sinanovic, O

2014-09-01

Executive function is very important in the children's overall development. The goal of this study was to assess the executive function in children with intellectual disability (ID) through the use of the Behavior Rating Inventory of Executive Function (BRIEF) teacher version. An additional goal was to examine the differences in executive function in relation to child's sex, level and aetiology of ID. The sample consisted of 90 children with ID attending two special education schools in Sarajevo, Bosnia and Herzegovina. There were 42 children with mild ID and 48 children with moderate ID. Of those, 54 were boys and 36 were girls. Children were classified into three etiological categories: 30 children with Down syndrome, 30 children with other genetic cause or organic brain injury and 30 children with unknown aetiology of ID. Special education teachers, who knew the children for at least 6 months filled the BRIEF. Children with ID had a significant deficit in executive function as measured by the BRIEF. There were no statistically significant differences in executive function in relation to the child's sex. Level of ID had a significant effect on executive function. In relation to the aetiology of ID, the only significant difference was on the Shift scale of the BRIEF. Knowing what executive function is most impaired in children with ID will help professionals design better intervention strategies. More attention needs to be given to the assessment of executive function and its subsequent intervention in the school settings. © 2013 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

1998-09-01

To examine the prevalence of intellectual dysfunctioning and its correlates in community-residing elderly people, a randomly selected sample of 1,405 people aged 65 and over living in Settsu, Osaka, were investigated in October 1992. Data for assessing intellectual dysfunctioning were obtained from 1,364 people (97.1%), excluding 21 clinically demented people (1.5%); 17.6/100, 5.6/100, and 3.3/100 of the population showed minor, moderate, and appreciable intellectual dysfunctioning, respectively, and the prevalence of intellectual dysfunctioning increased with age. By multivariate analyses using logistic regression, age over 75, poor general health, including current medical treatment, and psychosocial conditions such as no participation in social activities, no life worth living (no Ikigai), and anxiety about the future were independent risk factors for intellectual dysfunctioning. We conclude that intellectual dysfunctioning is closely associated with health and psychosocial conditions.

Control Beliefs and Cognition Over a 10-year Period: Findings from the ACTIVE Trial

PubMed Central

Parisi, Jeanine M.; Gross, Alden L.; Marsiske, Michael; Willis, Sherry L.; Rebok, George W.

2017-01-01

We examined two facets of control beliefs and cognition over ten-years within the ACTIVE cognitive training program. Intellectual Self-efficacy decreased (β = −0.32 units/year; SE = 0.03) and Concern about Intellectual Aging increased (β = 0.26 units/year; SE = 0.02) over time, with older age being the only predictor of increases in Concern about Intellectual Aging. Although baseline cognitive performance was related to control beliefs over time, the reverse was not supported. Findings were not altered by participation in the ACTIVE training programs, suggesting the need for including intervention components that lead to long-term maintenance or improvements in such beliefs.

2002-01-31

High motivation and belief in a cause have been reported to be protective against posttraumatic stress disorder (PTSD), while below-average intellectual functioning and poor educational achievements have been reported to increase vulnerability to PTSD. The main goal of this study was to assess the effect of education, and intellectual and behavioral functioning on the risk for future PTSD. Data collected before exposure to trauma, on intellectual and behavioral functioning, and educational achievements of 901 male Israeli adolescents who had performed pre-induction screening tests by the Israeli Draft Board, and were later diagnosed with PTSD, were compared with a control group of adolescents who were not later diagnosed with PTSD. Future PTSD patients had significantly lower intelligence, fewer years of formal education and lower scores on a scale assessing motivation to serve in the military, in comparison with the control group, with effect sizes (ES) ranging from 0.14-0.34. In contrast, future PTSD patients scored significantly higher on a scale assessing social functioning, ES=0.13. However, when controlling for the differences in motivation to serve, all of these differences disappeared. In this cohort, although slightly below average intellectual functioning and formal education, and better social functioning, independently increased vulnerability to suffer from PTSD, these associations disappeared when the future PTSD patients' lower motivation to serve in the military was included in the analysis. This suggests that low motivation to serve in the military might increase vulnerability for PTSD.

Fragile X syndrome (FXS) results in intellectual disability (ID) most often caused by silencing of the fragile X mental retardation 1 (FMR1) gene. The resulting absence of fragile X mental retardation protein 1 (FMRP) leads to both pre- and postsynaptic defects, yet whether the pre- and postsynaptic functions of FMRP are independent and have distinct roles in FXS neuropathology remain poorly understood. Here, we demonstrate an independent presynaptic function for FMRP through the study of an ID patient with an FMR1 missense mutation. This mutation, c.413G > A (R138Q), preserves FMRP’s canonical functions in RNA binding and translational regulation, which are traditionally associated with postsynaptic compartments. However, neuronally driven expression of the mutant FMRP is unable to rescue structural defects at the neuromuscular junction in fragile x mental retardation 1 (dfmr1)-deficient Drosophila, suggesting a presynaptic-specific impairment. Furthermore, mutant FMRP loses the ability to rescue presynaptic action potential (AP) broadening in Fmr1 KO mice. The R138Q mutation also disrupts FMRP’s interaction with the large-conductance calcium-activated potassium (BK) channels that modulate AP width. These results reveal a presynaptic- and translation-independent function of FMRP that is linked to a specific subset of FXS phenotypes. PMID:25561520

Neurofeedback training (NFT) has shown to be promising and useful to rehabilitate cognitive functions. Recently, brain-computer interfaces (BCIs) were used to restore brain plasticity by inducing brain activity with an NFT. In our study, we hypothesized that an NFT with a motor imagery-based BCI (MI-BCI) could enhance cognitive functions related to aging effects. To assess the effectiveness of our MI-BCI application, 63 subjects (older than 60 years) were recruited. This novel application was used by 31 subjects (NFT group). Their Luria neuropsychological test scores were compared with the remaining 32 subjects, who did not perform NFT (control group). Electroencephalogram changes measured by relative power (RP) endorsed cognitive potential findings under study: visuospatial, oral language, memory, intellectual and attention functions. Three frequency bands were selected to assess cognitive changes: 12, 18, and 21 Hz (bandwidth 3 Hz). Significant increases (p < 0.01) in the RP of these frequency bands were found. Moreover, results from cognitive tests showed significant improvements (p < 0.01) in four cognitive functions after performing five NFT sessions: visuospatial, oral language, memory, and intellectual. This established evidence in the association between NFT performed by a MI-BCI and enhanced cognitive performance. Therefore, it could be a novel approach to help elderly people.

2009-07-01

A functional polymorphism in the promoter of the gene encoding monoamine oxidase A has been associated with problem behavior in various populations. We examined the association of MAOA alleles in adult males with intellectual/developmental disabilities with and without established histories of problem behavior. These data were compared with a gender, ethnicity, and age-matched contrast sample. About 43% (15/35) of adults with intellectual/developmental disabilities and problem behavior possessed the low-efficiency version of the MAOA gene. In comparison, 20% (7/35) of adults with intellectual/developmental disabilities and no problem behavior and 20% (7/35) of the contrast group had the short-allele MAOA polymorphism. Therefore, a common variant in the MAOA gene may be associated with problem behavior in adults with intellectual/developmental disabilities.

Here we examined whether intellectual disability is independently associated with hyperglycaemia. We recruited 233 consecutive young and middle-aged adults with intellectual disability. After exclusion of subjects on medication for metabolic diseases or with severe intellectual disability (IQ < 35), 121 subjects were divided by IQ into a group with moderate intellectual disability (35 ≤ IQ ≤ 50), a mild intellectual disability group (51 ≤ IQ ≤ 70) and a borderline group (IQ > 70). HbA1c level was higher in subjects with moderate intellectual disability (42 ± 9 mmol/mol; 6.0 ± 0.8%) than those in the borderline group (36 ± 4 mmol/mol; 5.5 ± 0.3%) and mild intellectual disability group (37 ± 5 mmol/mol; 5.5 ± 0.5%) groups. HbA1c level was correlated with age, BMI, blood pressure, serum triglycerides and IQ in simple linear regression analysis. Multiple regression analysis indicated that IQ, age, BMI and diastolic blood pressure were independent explanatory factors of HbA1c level. An unfavourable effect of intellectual disability on lifestyle and untoward effect of hyperglycaemia on cognitive function may underlie the association of low IQ with hyperglycaemia. © 2014 The Authors.

Important aspects of participation and participation restrictions in people with a mild intellectual disability.

PubMed

Arvidsson, Patrik; Granlund, Mats; Thyberg, Ingrid; Thyberg, Mikael

2014-01-01

This study explored a possibility to assess the concepts of participation and participation restrictions in the International Classification of Functioning, Disability and Health (ICF) by combining self-ratings of the perceived importance with the actual performance of different everyday activities in people with a mild intellectual disability. Structured interviews regarding 68 items from the ICF activity/participation domain were conducted (n = 69). The items were ranked by perceived importance, performance and by combined measures. Furthermore, the measures were related to a single question about subjective general well-being. Rankings of performance highlighted about the same items as "important participation", while rankings of low performance addressed quite different items compared with "important participation restriction". Significant correlations were found between subjective general well-being and high performance (r = 0.56), high performance/high importance (important participation) (r = 0.56), low performance (r = -0.56) and low performance/high importance (important participation restriction; r = -0.55). The results support the clinical relevance of the ICF and the studied selection of 68 items. Although performance only may sometimes be a relevant aspect, knowledge about the relationship between the perceived importance and the actual performance is essential for clinical interventions and for research aiming to understand specific needs regarding participation. The concepts of participation and participation restriction are highly relevant in people with a mild intellectual disability. Self-rated performance might be sufficient to assess participation at a group level. In clinical practices, the relationship between the perceived importance and the actual performance of an activity is essential to assess.

Jo, Garam; Rossow-Kimball, Brenda; Lee, Yongho

2018-04-01

The current study examined the effects of an exercise program on health related physical fitness, self-efficacy, and physical activity levels in adults with intellectual disability. The study used pre- and posttest experimental research design with a control group. Total of 23 adults with intellectual disability were recruited with 12 assigned for the exercise group and 11 for the control group, separately. The measures of health related physical fitness included cardio pulmonary endurance (step-test), body composition (bioelectrical impedance analysis), flexibility (sit and reach), muscle endurance (sit-up), and strength (hand grip strength). Self-efficacy was measured using the physical self-efficacy scale. Accelerometers were used to measure physical activity levels. All variables were measured and evaluated twice at baseline and at the end of the program. The exercise program consisted of band exercises and rhythmic activity for 90 min, twice per week for 12 weeks. After the intervention, significant improvements were found in the experimental group in muscle endurance, self-efficacy, and physical activity levels. An exercise program may be recommended as a nonpharmaceutical method to improve the health of adults with intellectual disabilities.

Earlier research and clinical practice show that specific language impairment (SLI) is often associated with nonverbal cognitive deficits and weakened skills in executive functions (EFs). Executive deficits may have a remarkable influence on a child's everyday activities in the home and school environments. However, research information is still limited on EFs in school-aged children with SLI, mostly conducted among English- and Dutch-speaking children. To study whether there are differences in EFs between Finnish-speaking children with SLI and typically developing (TD) peers at school age. EFs are compared between the groups with and without controlling for nonverbal intelligence. Parents and teachers of children with SLI (n = 22) and age- and gender-matched TD peers (n = 22) completed The Behavior Rating Inventory of Executive Functions (BRIEF). The mean age of the children was 8,2 years. BRIEF ratings of parents and teachers were compared between the children with SLI and with TD peers by paired analysis using conditional logistic regression models with and without controlling for nonverbal IQ. Intellectual functioning was assessed with the Wechsler Intelligence Scale for Children. Children with SLI had weaker scores in all parent and teacher BRIEF scales compared with TD peers. Statistically significant differences between the groups were found in BRIEF scales Shift, Emotional Control, Initiate, Working Memory, Plan/Organize and Monitor. Differences between the groups were statistically significant also in intellectual functioning. On BRIEF scales some group differences remained statistically significant after controlling for nonverbal IQ. This study provides additional evidence that also Finnish-speaking school-aged children with SLI are at risk of having deficits in EFs in daily life. EFs have been proposed to have an impact on developmental outcomes later in life. In clinical practice it is important to pay attention to EFs in school-aged children with SLI when making diagnostic evaluations and planning interventions for them. © 2016 Royal College of Speech and Language Therapists.

Understanding Intellectual Disability through Rasopathies

Alvaro, San Martín; Rafael, Pagani Mario

2014-01-01

Intellectual disability, commonly known as mental retardation in the International Classification of Disease from World Health Organization, is the term that describes an intellectual and adaptive cognitive disability that begins in early life during the developmental period. Currently the term intellectual disability is the preferred one. Although our understanding of the physiological basis of learning and learning disability is poor, a general idea is that such condition is quite permanent. However, investigations in animal models suggest that learning disability can be functional in nature and as such reversible through pharmacology or appropriate learning paradigms. A fraction of the cases of intellectual disability is caused by point mutations or deletions in genes that encode for proteins of the RAS/MAP Kinase signaling pathway known as RASopathies. Here we examined the current understanding of the molecular mechanisms involved in this group of genetic disorders focusing in studies which provide evidence that intellectual disability is potentially treatable and curable. The evidence presented supports the idea that with the appropriate understanding of the molecular mechanisms involved, intellectual disability could be treated pharmacologically and perhaps through specific mechanistic-based teaching strategies.

p.(Arg320His) mutation in the KCNC1 gene in human 11p15.1 has recently been identified in patients with progressive myoclonus epilepsies, a group of rare inherited disorders manifesting with action myoclonus, myoclonic epilepsy, and ataxia. This KCNC1 variant causes a dominant-negative effect. Here we describe three patients from the same family with intellectual disability and dysmorphic features. The three affected individuals carry a c.1015C>T (p.(Arg339*)) nonsense variant in KCNC1 gene. As previously observed in the mutant mouse carrying a disrupted KCNC1 gene, these findings reveal that individuals with a KCNC1 loss-of-function variant can present intellectual disability without seizure and epilepsy.

Intellectual disability refers to substantial limitations in intellectual functioning, affecting 0.7-1.5% of the population. People with intellectual disability have higher rates of obesity, since caloric values and nutritional status, are deficient. To determine the nutritional habits, analyze the effectiveness of nutritional education and evaluate the possible effect of improvement introducing exercise and nutrition workshops, in a group of people with intellectual disability. Clinical, nutritional and anthropometric (weight, height, body mass index, body fat, waist circumference) assessment was conducted in 47 patients. An ad hoc survey was designed in which exercise habits, medical and dietary history, record of 72 hours (including 2 weekdays and 1 weekend) and the adherence to Mediterranean diet data were collected. The workshops of exercise and nutrition counted with a structure of theoretical-practical explanation and games. 76.1% presented weight excess at baseline. After the intervention values of total body fat (-0.94 ± 4.4%) and visceral fat (-0.86 ± 2%), weight (-0.4 ± 3.3 kg) and body mass index (-0.2 ± 1.6 kg/m2) decreased, more in women than in men. 60.5% of subjects did not meet a high adherence to the Mediterranean diet. After nutritional intervention, a significant difference (p <= 0,001) was observed in the KidMed score. The workshop of physical activity had positive effects on the anthropometry of subjects. Both the intake and the prevalence of obesity in this group of people are inadequate. Nutritional education and physical exercise workshops are useful for working with this group, achieving significant changes to prevent obesity and improve their health.

The 22q11.2 deletion syndrome (22qDS) and schizophrenia have genetic and neuropsychological similarities, but are likely to differ in memory profile. Confirming differences in memory function between the two disorders, and identifying their genetic determinants, can help to define genetic subtypes in both syndromes, identify genetic risk factors for the emergence of psychosis, and develop pharmacological interventions for cognitive dysfunction. However, no study has compared memory function between 22qDS and schizophrenia, while indirect comparisons are confounded by marked differences in IQ between the two populations. We compared verbal and visual memory in 29 children and adolescents with 22qDS and 15 intellectually matched youths with schizophrenia using age-appropriate, directly comparable, Wechsler scales. Verbal memory was markedly superior in the 22qDS group by 21 points. There were no group differences in visual memory. The inherently low COMT activity in 22qDS merits investigation as a potential protective factor for verbal memory. 2010 Elsevier Ltd. All rights reserved.

This study was conducted to describe the functioning of Activities of Daily Living (ADL) and to examine socio-economic effects on ADL functioning among adults with intellectual disabilities (ID) aged 45 years and older (N=480) in Taiwan. The Barthel Index (BI) was used to determine a baseline level of ADL functioning in the study participants. There are five categories of functional impairment using the following cut-off values in Taiwan: total dependence (BI score 0-20), severe (BI score 21-60), moderate (BI score 61-90), mild (BI score 91-99), and total independence (BI score 100) (Taiwan Department of Health, 2012). The results revealed that 2.3% of adults with ID were in total dependence, 11.9% were in severe dependence, 27.9% were in moderate dependence, 8.1% had a mild dependence, and 49.8% were totally independent. In the multiple linear regression model of the ADL score, we determined that educational level, comorbid Down's syndrome, and disability level are the variables able to significantly predict ADL score (R(2)=0.190) after controlling for the factors of age, marital status, and other comorbidity conditions. Those ID adults with a lower education level (primary vs. literate, β=4.780, p=0.031; intermediate vs. literate, β=6.642, p=0.030), with comorbid Down's syndrome (β=-7.135, p=0.063), and with a more severe disability condition (severe vs. mild, β=-7.650, p=0.007; profound vs. mild, β=-19.169, p<0.001) had significantly lower ADL scores. The present study highlights the need to support mobility in older adults with ID as much as possible to optimize independence in this group. Copyright © 2013 Elsevier Ltd. All rights reserved.

To assess the decision-making capacity and variables related to this, in elderly patients in a home care program. A cross-sectional study was conducted on 130 patients assigned to home care program or in social welfare residences of an urban health centre. Demographic variables, as well as comorbidities, social support, institutionalisation, number of drugs used, degree of dependence (Barthel Index), cognitive function (Pfeiffer) were collected. The primary endpoint was the capacity for decision-making about their health assessed using the Aid to Capacity Evaluation (ACE) tool. There was a prevalence of 58.5% capacity. There was an association between ability and independence for activities of daily living (odds ratio (OR): 12.214; Confidence interval 95% (95% CI): 3.90 to 32.29, P <.0001) and function intellectual intact (OR: 282.750, 95% CI 34.0 to 2351.2, P <.0001). Numeric variables associated with the capacity for decision-making that had a more important effect size were the Barthel index (d: -1.398) and Pfeiffer index (d: 3.084). The prevalence of incapacity to make decisions about their health in elderly patients who are cared for in their homes is high. The level of dependence in activities of daily living and the deterioration of intellectual function are factors associated with the presence of this capacity.

People with Intellectual Disability (ID) have cognitive impairments that affect their level of functioning the causes of which are multiple and often unknown. Behavioural difficulties are common among people with ID. Attention Deficit Hyperactivity Disorder (ADHD) is recognised more among people with Intellectual Disability and could be a cause of problem behaviours. Screening and assessing for ADHD in people with ID is difficult because of the paucity of robust assessment tools and diagnostic criteria.

Histamine (HA) acts as a neurotransmitter in the brain, which participates in the regulation of many biological processes including inflammation, gastric acid secretion and neuromodulation. The enzyme histamine N-methyltransferase (HNMT) inactivates HA by transferring a methyl group from S-adenosyl-l-methionine to HA, and is the only well-known pathway for termination of neurotransmission actions of HA in mammalian central nervous system. We performed autozygosity mapping followed by targeted exome sequencing and identified two homozygous HNMT alterations, p.Gly60Asp and p.Leu208Pro, in patients affected with nonsyndromic autosomal recessive intellectual disability from two unrelated consanguineous families of Turkish and Kurdish ancestry, respectively. We verified the complete absence of a functional HNMT in patients using in vitro toxicology assay. Using mutant and wild-type DNA constructs as well as in silico protein modeling, we confirmed that p.Gly60Asp disrupts the enzymatic activity of the protein, and that p.Leu208Pro results in reduced protein stability, resulting in decreased HA inactivation. Our results highlight the importance of inclusion of HNMT for genetic testing of individuals presenting with intellectual disability. PMID:26206890

Adults with intellectual disability experience substantial health inequities. Public health research aiming to improve the lives of this population group is needed. We sought to investigate the extent to which a sample of international public health research includes and identifies people with intellectual disability. In this systematic review, we examined a select number of public health journals to determine (1) how often people with intellectual disability are explicitly included in randomised controlled trials (RCTs) and cohort studies and (2) how the presence of intellectual disability is identified and reported. Among eligible articles in these selected public health journals, it was found that cohort studies passively exclude people with intellectual disability, while RCTs actively exclude this population. Most general population articles that explicitly identified people with intellectual disability did so through self-report or proxy report and databases. A more extensive and adequate evidence base relating to the health of this overlooked population group is needed. A useful first step would be for researchers specialising in intellectual disability to identify how we can best assist mainstream researchers to include and identify people with intellectual disability in their population-level studies. © Royal Society for Public Health 2014.

Changes in Leisure Activities and Dimensions of Depressive Symptoms in Later Life: A 12-Year Follow-Up.

PubMed

Chao, Shiau-Fang

2016-06-01

Although leisure activities benefit the mental health of the elderly population, the effect of changes in leisure activities on dimensions of depressive symptoms remains unclear. This investigation examined the influences of changes in intellectual, social, and physical activities between waves on four dimensions of depressive symptoms at follow-up. Random effects modeling was utilized with data from a nationwide longitudinal study conducted in Taiwan. The study data comprised 6,942 observations from 2,660 older adults over a 12-year period. The results suggested that changes in physical activities contributed to depressive symptoms which reflected positive affect in the later wave. Increased social activities between waves predicted higher positive affect and lower interpersonal difficulties scores at follow-up. Increased intellectual activities between waves did not substantially affect any domain of depressive symptoms. In contrast, declines in intellectual activities between waves predicted higher scores in three depressive symptoms domains, including depressed mood, somatic symptoms, and interpersonal difficulties. Engagement in a varied range of activities benefits mental health among elders more than participation in any single type of activity among elders. Reducing physical activities can lower positive affect, while the adverse effect may be balanced by increasing social activities. Also, the impact of decreasing intellectual activities on the interpersonal difficulties domain of depressive symptoms may be offset by increasing social activities. © The Author 2014.

2014-05-01

The main purpose of this investigation was to identify patterns of intellectual performance in schizophrenia patients suggesting preserved, deteriorated, and premorbidly impaired ability, and to determine clinical, cognitive, and functional correlates of these patterns. We assessed 101 patients with schizophrenia or schizoaffective disorder and 80 non-psychiatric control participants. The "preserved" performance pattern was defined by average-range estimated premorbid and current IQ with no evidence of decline (premorbid-current IQ difference <10 points). The "deteriorated" pattern was defined by a difference between estimated premorbid and current IQ estimates of 10 points or more. The premorbidly "impaired" pattern was defined by below average estimated premorbid and current IQ and no evidence of decline greater than 10 points. Preserved and deteriorated patterns in healthy controls were also identified and studied in comparison to patient findings. The groups were compared on demographic, neurocognitive, clinical and functionality variables. Patients with the preserved pattern outperformed those meeting criteria for deteriorated and compromised intellectual ability on a composite measure of neurocognitive ability as well as in terms of functional competence. Patients demonstrating the deteriorated and compromised patterns were equivalent across all measures. However, "preserved" patients failed to show any advantage in terms of community functioning and demonstrated cognitive impairments relative to control participants. Our results suggest that proposed patterns of intellectual decline and stability exist in both the schizophrenia and general populations, but may not hold true across other cognitive abilities and do not translate into differential functional outcome.

Risk for developing a learning disability (LD) or impaired intellectual functioning by age 7 was assessed in full-term children with prenatal cocaine exposure drawn from a cohort of 476 children born full term and enrolled prospectively at birth. Intellectual functioning was assessed using the Wechsler Intelligence Scale for Children-Third Edition (Wechsler, 1991) short form, and academic functioning was assessed using the Wechsler Individual Achievement Test (WIAT; Wechsler, 1993) Screener by examiners blind to exposure status. LDs were categorized based on ability-achievement discrepancy scores, using the regression-based predicted achievement method described in the WIAT manual. The sample in this report included 409 children (212 cocaine-exposed, 197 non-cocaine-exposed) from the birth cohort with available data. Cumulative incidence proportions and relative risk values were estimated using STATA software (Statacorp, 2003). No differences were found in the estimate of relative risk for impaired intellectual functioning (IQ below 70) between children with and without prenatal cocaine exposure (estimated relative risk = .95; 95% confidence interval [CI] = 0.65, 1.39; p = .79). The cocaine-exposed children had 2.8 times greater risk of developing a LD by age 7 than non-cocaine-exposed children (95% CI = 1.05, 7.67; p = .038; IQ >/= 70 cutoff). Results remained stable with adjustment for multiple child and caregiver covariates, suggesting that children with prenatal cocaine exposure are at increased risk for developing a learning disability by age 7 when compared to their non-cocaine-exposed peers.

RLIM, also known as RNF12, is an X-linked E3 ubiquitin ligase acting as a negative regulator of LIM-domain containing transcription factors and participates in X-chromosome inactivation (XCI) in mice. We report the genetic and clinical findings of 84 individuals from nine unrelated families, eight of whom who have pathogenic variants in RLIM (RING finger LIM domain-interacting protein). A total of 40 affected males have X-linked intellectual disability (XLID) and variable behavioral anomalies with or without congenital malformations. In contrast, 44 heterozygous female carriers have normal cognition and behavior, but eight showed mild physical features. All RLIM variants identified are missense changes co-segregating with the phenotype and predicted to affect protein function. Eight of the nine altered amino acids are conserved and lie either within a domain essential for binding interacting proteins or in the C-terminal RING finger catalytic domain. In vitro experiments revealed that these amino acid changes in the RLIM RING finger impaired RLIM ubiquitin ligase activity. In vivo experiments in rlim mutant zebrafish showed that wild type RLIM rescued the zebrafish rlim phenotype, whereas the patient-specific missense RLIM variants failed to rescue the phenotype and thus represent likely severe loss-of-function mutations. In summary, we identified a spectrum of RLIM missense variants causing syndromic XLID and affecting the ubiquitin ligase activity of RLIM, suggesting that enzymatic activity of RLIM is required for normal development, cognition and behavior.

Our aim was to investigate the correlations between patterns of head growth and intellectual disability among distinct aetiological presentations of microcephaly. 3,269 head circumference (HC) charts of patients from a tertiary neuropediatric unit were reviewed and 136 microcephalic participants selected. Using the Z-scores of registered HC measurements we defined the variables: HC Minimum, HC Drop and HC Catch-up. We classified patients according to the presence or absence of intellectual disability (IQ below 71) and according to the cause of microcephaly (idiopathic, familial, syndromic, symptomatic and mixed). Using Discriminant Analysis a C-function was defined as C=HC Minimum + HC Drop with a cut-off level of C=-4.32 Z-score. In our sample 95% of patients scoring below this level, severe microcephaly, were classified in the disabled group while the overall concordance was 66%. In the symptomatic-mixed group the concordance between HC function and outcome reached 82% in contrast to only 54% in the idiopathic-syndromic group (P-value=0.0002). We defined a HC growth function which discriminates intellectual disability of microcephalic patients better than isolated HC measurements, especially for those with secondary and mixed aetiologies.

Borderline intellectual functioning and sleep: the role of cyclic alternating pattern.

PubMed

Esposito, Maria; Carotenuto, Marco

2010-11-19

In the clinical literature there are few specific studies about the relationship between cognition processes and sleep during childhood. In addition, milder deficits in general intellectual capacity have received less attention relative to major cognitive dysfunctions (such as the genetic or environmental basis of mental retardation), especially concerning the low normal and borderline status. Sleep could play a key role in multiple intellectual abilities such as memory, executive functions, and school performances. Aim of our study is to assess the sleep macrostructure and NREM instability (cyclic alternating pattern) and their relationship with IQ in a sample of subjects with borderline intellectual functioning (BIF). The DSM-IV defines BIF as a total intelligence quotient (TIQ) ranging between 71 and 84. Intellective functioning was assessed using the Italian version of Wechsler Intelligence Scale for Children-Revised (WISC-R), a well validated test for the developmental age between 6 and 16. For this study, 12 BIF and 17 healthy children, matched for sex and age, underwent an overnight PSG recording. Macrostructural sleep and CAP analysis were also performed. To our knowledge, this study represents the first attempt to evaluate sleep architecture and NREM instability organization in children with BIF. Findings from this investigation evidence that BIF presents alterations in both macro- and microstructural sleep architecture, with an interesting statistical significant correlation with IQ.

Background Autosomal-recessive non-syndromic intellectual disability (ARNS-ID) is an aetiologically heterogeneous disorder. Although little is known about the function of human cereblon (CRBN), its relationship to mild cognitive deficits suggests that it is involved in the basic processes of human memory and learning. Objectives We aim to identify the genetic cause of intellectual disability and self-mutilation in a consanguineous Saudi family with five affected members. Methods Clinical whole-exome sequencing was performed on the proband patient, and Sanger sequencing was done to validate and confirm segregation in other family members. Results A missense variant (c. 1171T>C) in the CRBN gene was identified in five individuals with severe intellectual disability (ID) in a consanguineous Saudi family. The homozygous variant was co-segregating in the family with the phenotype of severe ID, seizures and self-mutilating behaviour. The missense mutation (p.C391R) reported here results in the replacement of a conserved cysteine residue by an arginine in the CULT (cereblon domain of unknown activity, binding cellular ligands and thalidomide) domain of CRBN, which contains a zinc-binding site. Conclusions These findings thus contribute to a growing list of ID disorders caused by CRBN mutations, broaden the spectrum of phenotypes attributable to ARNS-ID and provide new insight into genotype–phenotype correlations between CRBN mutations and the aetiology of ARNS-ID.

Intelligence quotient (IQ) is a standardized measure of human intellectual capacity that takes into account a wide range of cognitive skills. IQ is generally considered to be stable across the lifespan, with scores at one time point used to predict educational achievement and employment prospects in later years. Neuroimaging allows us to test whether unexpected longitudinal fluctuations in measured IQ are related to brain development. Here we show that verbal and non-verbal IQ can rise or fall in the teenage years, with these changes in performance validated by their close correlation with changes in local brain structure. A combination of structural and functional imaging showed that verbal IQ changed with grey matter in a region that was activated by speech, whereas non-verbal IQ changed with grey matter in a region that was activated by finger movements. By using longitudinal assessments of the same individuals, we obviated the many sources of variation in brain structure that confound cross-sectional studies. This allowed us to dissociate neural markers for the two types of IQ and to show that general verbal and non-verbal abilities are closely linked to the sensorimotor skills involved in learning. More generally, our results emphasize the possibility that an individual's intellectual capacity relative to their peers can decrease or increase in the teenage years. This would be encouraging to those whose intellectual potential may improve, and would be a warning that early achievers may not maintain their potential.

Intellectual developmental disorders: towards a new name, definition and framework for "mental retardation/intellectual disability" in ICD-11.

Although "intellectual disability" has widely replaced the term "mental retardation", the debate as to whether this entity should be conceptualized as a health condition or as a disability has intensified as the revision of the World Health Organization (WHO)'s International Classification of Diseases (ICD) advances. Defining intellectual disability as a health condition is central to retaining it in ICD, with significant implications for health policy and access to health services. This paper presents the consensus reached to date by the WHO ICD Working Group on the Classification of Intellectual Disabilities. Literature reviews were conducted and a mixed qualitative approach was followed in a series of meetings to produce consensus-based recommendations combining prior expert knowledge and available evidence. The Working Group proposes replacing mental retardation with intellectual developmental disorders, defined as "a group of developmental conditions characterized by significant impairment of cognitive functions, which are associated with limitations of learning, adaptive behaviour and skills". The Working Group further advises that intellectual developmental disorders be incorporated in the larger grouping (parent category) of neurodevelopmental disorders, that current subcategories based on clinical severity (i.e., mild, moderate, severe, profound) be continued, and that problem behaviours be removed from the core classification structure of intellectual developmental disorders and instead described as associated features.

2015-01-01

Intellectual giftedness is associated with strong strategic verbal memory while attention-deficit hyperactivity disorder (ADHD) is associated with strategic verbal memory deficits; however, no previous research has explored how this contradiction manifests in gifted populations with diagnoses of ADHD. The purpose of this study was to explore strategic verbal memory processes among intellectually gifted youth with and without ADHD to provide clarification regarding this specific aspect of neuropsychological functioning within this population. One hundred twenty-five youth completed neuropsychological evaluations including the Wechsler Intelligence Scale for Children-Fourth Edition and California Verbal Learning Test-Children's Version (CVLT-C). Results revealed significant differences between groups, with intellectually gifted youth with ADHD achieving lower T scores on CVLT-C Trials 1 through 5 compared with intellectually gifted youth without ADHD, and intellectually gifted youth with ADHD achieving higher T scores than youth of average intellectual abilities with ADHD. Additionally, repeated-measures analysis of variance revealed a main effect improvement among gifted youth with ADHD in short-delay recall when provided with organizational cues. Findings revealed new evidence about the role of twice exceptionality (specifically intellectual giftedness and ADHD) in strategic verbal memory and have important implications for parents, educators, psychologists and neuropsychologists, and other mental health professionals working with this population.

Music for All: Including young people with intellectual disability in a university environment.

PubMed

Rickson, Daphne; Warren, Penny

2017-01-01

We investigated a continuing education course in creative music making, initiated to promote the inclusion of young people with intellectual disability in a university setting. Despite organizers' attempts to foster diversity within the student cohort, enrolments were almost exclusively from students who had intellectual disability. Being in the university environment, and in a place of higher learning, seemed to be valued by some. However, students' main focus was on group musicking in a dedicated music room rather than interacting with the wider university community. Those who did not identify as disabled believed it was important to continue to address the barriers to wider inclusion. While acknowledging the risks around mediating the social interactions of young people with intellectual disability, we argue that future courses should include activities specifically designed to bring them to classes with typical students and to the wider activities of the university.

To examine the association of job characteristics and intelligence to cognitive status in members of the National Academy of Sciences-National Research Council Twins Registry of World War II veterans. Participants (n = 1,036) included individuals with an assessment of intelligence based on Armed Services testing in early adulthood. In late adulthood, these individuals completed the modified Telephone Interview for Cognitive Status (TICS-m) and occupational history as part of an epidemiologic study of aging and dementia. Occupational history was coded to produce a matrix of job characteristics. Based on factor analysis, job characteristics were interpreted as reflecting general intellectual demands (GI), human interaction and communication (HC), physical activity (PA), and visual attention (VA). Based on regression analysis of TICS-m score covarying for age, intelligence, and years of education, higher levels of GI and HC were independently associated with higher TICS-m performance, whereas higher PA was independently associated with lower performance. There was an interaction of GI and intelligence, indicating that individuals at the lower range of intellectual aptitude in early adulthood derived greater cognitive benefit from intellectually demanding work. Intellectually demanding work was associated with greater benefit to cognitive performance in later life independent of related factors like education and intelligence. The fact that individuals with lower intellectual aptitude demonstrated a stronger positive association between work and higher cognitive performance during retirement suggests that behavior may enhance intellectual reserve, perhaps even years after peak intellectual activity.

2018-04-01

Although individuals with intellectual and developmental disabilities (IDD) are living longer lives, fewer than half of parents of individuals with IDD conduct future planning. The correlates and barriers to future planning must be identified to develop targeted interventions to facilitate future planning. In this study, 388 parents of individuals with IDD responded to a national, web-based survey. Participants who were older, more educated, attended more parent training and support activities, and had children with fewer functional abilities, were more likely to engage in future planning. Reported barriers to future planning included: (a) lack of available services, (b) financial challenges, (c) reluctance of family members, (d) lack of time, (e) the emotional nature of future planning, (f) inertia, and (g) a lack of family members to be caregivers. Implications for policy, practice, and future research are discussed.

GATA zinc finger domain-containing 2B (GATAD2B) is a subunit of the methyl-CpG-binding protein-1 complex (MECP1), which deacetylates methylated nucleosomes and regresses transcriptional activity. Recently, GATAD2B has been elucidated as a candidate gene in patients with intellectual disability (ID). In this study, we identified two novel heterozygous frameshift mutations of GATAD2B in two unrelated ID cases through next-generation sequencing (NGS). Both of the mutations c.80_81insGATGT and c.552_555delGAAA cause truncated proteins that might be detrimental to neurodevelopment. We performed western blotting and observed a reduction in the target protein compared with normal controls. This is the first report of GATAD2B in Chinese ID patients. Our findings will broaden the spectrum of GATAD2B mutations and facilitate genetic diagnosis and counseling.

Slack, Slick, and Sodium-Activated Potassium Channels

PubMed Central

Kaczmarek, Leonard K.

2013-01-01

The Slack and Slick genes encode potassium channels that are very widely expressed in the central nervous system. These channels are activated by elevations in intracellular sodium, such as those that occur during trains of one or more action potentials, or following activation of nonselective cationic neurotransmitter receptors such as AMPA receptors. This review covers the cellular and molecular properties of Slack and Slick channels and compares them with findings on the properties of sodium-activated potassium currents (termed KNa currents) in native neurons. Human mutations in Slack channels produce extremely severe defects in learning and development, suggesting that KNa channels play a central role in neuronal plasticity and intellectual function.

2017-10-01

This study investigates the differential functioning of cultural and intellectual openness (the two aspects of Openness to Experience) in relation to social cognitive processes by examining how they influence people's perceptions and interpretations of social information when deciding to initiate working relationships. Using a policy-capturing design, 681 adult participants were asked to rate their similarity to and preference to work with potential work partners characterized by varying nationalities and levels of work-related competence. Multilevel moderated mediation was conducted to simultaneously evaluate whether the indirect effects of potential work partners' characteristics (i.e., nationalities and levels of work-related competence) on work partner preference through perceived similarity were moderated by cultural and intellectual openness. Perceived similarity mediated the relationships between work partner nationality and work-related competence and participants' work partner preferences. Furthermore, the negative indirect effect of work partner nationality on work partner preference via perceived similarity was attenuated by cultural openness, and the positive indirect effect of work partner work-related competence on work partner preference via perceived similarity was strengthened by intellectual openness. Cultural and intellectual openness may have distinct functions that influence how people perceive, evaluate, and appreciate social information when making social judgments. © 2016 Wiley Periodicals, Inc.

Language in low-functioning children with autistic disorder: differences between receptive and expressive skills and concurrent predictors of language.

Maljaars, Jarymke; Noens, Ilse; Scholte, Evert; van Berckelaer-Onnes, Ina

2012-10-01

Language profiles of children with autistic disorder and intellectual disability (n = 36) were significantly different from the comparison groups of children with intellectual disability (n = 26) and typically developing children (n = 34). The group low-functioning children with autistic disorder obtained a higher mean score on expressive than on receptive language, whereas both comparison groups showed the reverse pattern. Nonverbal mental age, joint attention, and symbolic understanding of pictures were analyzed in relation to concurrent receptive and expressive language abilities. In the group with autistic disorder and intellectual disability, symbol understanding and joint attention were most strongly related to language abilities. Nonverbal mental age was the most important predictor of language abilities in the comparison groups.

2015-05-01

The aim of this study was to support the growing evidence suggesting that Prader-Willi Syndrome (PWS) might present with an impairment of executive functions (EFs) and to investigate whether this impairment is specific to patients with PWS or due to their intellectual disability (ID). Six tasks were administered to assess EFs (inhibition, switching, updating, cognitive estimation, and planning) to 17 patients with PWS and 17 age-matched healthy individuals. Performance was significantly impaired in the PWS group on all EFs and after controlling for IQ level, intergroup differences remained only for switching and cognitive estimation. In conclusion, PWS seems to be associated with a global impairment of EFs that appears to be closely linked with intellectual impairment but also with the PWS itself.

Pedophiles: mental retardation, maternal age, and sexual orientation.

1999-04-01

Intellectual functioning, parental age, and sexual orientation in 991 male sexual offenders were investigated. Sources of data included semistructured interviews, clinical charts, phallometric tests, and self-administered questionnaires. The results suggest two main conclusions: (i) Among pedophiles in general, erotic preference moves away from adult women along two dimensions: age and sex. The extent of this movement is greater, along both dimensions, for pedophiles with lower levels of intellectual functioning. (ii) High maternal age (or some factor it represents) increases the likelihood of exclusive sexual interest in boys. Intellectual deficiency (or some factor it represents) decreases the likelihood of exclusive sexual interest in girls. These two factors summate, so that a pedophile with both factors is more likely to be sexually interested in boys than a pedophile with only one.

2010-08-12

Instigation of proper measures in case of intellectual disability is often conditioned by a diagnosis. Our aim was to assess whether the Hayes Ability Screening Index (HASI) is a suitable screening instrument for intellectual disability among adults. The article is based on three former studies aimed at validating HASI for use among patients referred for neuropsychological examination, prison inmates and psychiatric inpatients in community mental health centres. The sample consisted of 264 persons. The HASI correlated with the more comprehensive scales of assessing intellectual functioning (Wechsler tests) (r = 0.73, p < 0.001). With a cut-off value of 85, HASI had a sensitivity of 0.97 and a specificity of 0.61 in relation to an IQ < 70. HASI is associated with few false negatives, but a large number of false positives. This implies that an intellectual disability is concluded in too many cases; a positive screening should be followed up with a more thorough assessment.

Little is known about the experience of growing up with a mother with intellectual disability. The aim of this study was to explore this experience from the perspective of adult children. In-depth interviews with 23 adult children brought up by mothers with moderate-to-severe intellectual disability. The interview data were analysed using grounded theory methods. The childhood experiences of the interviewees and the role their mothers played in their upbringing varied, depending in part on the involvement of extended family. It was the stigma of maternal intellectual disability, rather than their mother's functional limitations, that posed the greatest challenge. Interviewees characterized their mothers and childhoods as different, yet ordinary. Understanding the social context, including but not limited to the availability of informal support, is critical to understanding the experience of children growing up with mothers with intellectual disability. © 2017 John Wiley & Sons Ltd.

Social cognition dysfunction in adolescents with 22q11.2 deletion syndrome (velo-cardio-facial syndrome): relationship with executive functioning and social competence/functioning.

PubMed

Social difficulties are often noted among people with intellectual disabilities. Children and adults with 22q.11.2 deletion syndrome (22q11DS) often have poorer social competence as well as poorer performance on measures of executive and social-cognitive skills compared with typically developing young people. However, the relationship between social functioning and more basic processes of social cognition and executive functioning are not well understood in 22q11DS. The present study examined the relationship between social-cognitive measures of emotion attribution and theory of mind with executive functioning and their contribution to social competence in 22q11DS. The present cross-sectional study measured social cognition and executive performance of 24 adolescents with 22q11DS compared with 27 age-matched typically developing controls. Social cognition was tested using the emotion attribution task (EAT) and a picture sequencing task (PST), which tested mentalising (false-belief), sequencing, cause and effect, and inhibition. Executive functioning was assessed using computerised versions of the Tower of London task and working memory measures of spatial and non-spatial ability. Social competence was also assessed using the parent-reported Strengths and Difficulties Questionnaire. Adolescents with 22q11DS showed impaired false-belief, emotion attribution and executive functioning compared with typically developing control participants. Poorer performance was reported on all story types in the PST, although, patterns of errors and response times across story types were similar in both groups. General sequencing ability was the strongest predictor of false-belief, and performance on the false-belief task predicted emotion attribution accuracy. Intellectual functioning, rather than theory of mind or executive functioning, predicted social competence in 22q11DS. Performance on social-cognitive tasks of theory of mind indicate evidence of a general underlying dysfunction in 22q11DS that includes executive ability to understand cause and effect, to logically reason about social scenarios and also to inhibit responses to salient, but misleading cues. However, general intellectual ability is closely related to actual social competence suggesting that a generalised intellectual deficit coupled with more specific executive impairments may best explain poor social cognition in 22q11DS. © 2015 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

The Borderline Intellectual Functioning (BIF) is conceptualized as the frontier that delimits "normal" intellectual functioning from intellectual disability (IQ 71-85). In spite of its magnitude, its prevalence cannot be quantified and its diagnosis has not yet been defined. To elaborate a conceptual framework and to establish consensus guidelines. A mixed qualitative methodology, including frame analysis and nominal groups techniques, was used. The literature was extensively reviewed in evidence based medical databases, scientific publications, and the grey literature. This information was studied and a framing document was prepared. Scientific publications covering BIF are scarce. The term that yields a bigger number of results is "Borderline Intelligence". The Working Group detected a number of areas in which consensus was needed and wrote a consensus document covering the conclusions of the experts and the framing document. It is a priority to reach an international consensus about the BIF construct and its operative criteria, as well as to develop specific tools for screening and diagnosis. It is also necessary to define criteria that enable its incidence and prevalence. To know what interventions are the most efficient, and what are the needs of this population, is vital to implement an integral model of care centred on the individual. Copyright © 2011 SEP y SEPB.

The recent identification of multiple dominant mutations in the gene encoding β-catenin in both humans and mice has enabled exploration of the molecular and cellular basis of β-catenin function in cognitive impairment. In humans, β-catenin mutations that cause a spectrum of neurodevelopmental disorders have been identified. We identified de novo β-catenin mutations in patients with intellectual disability, carefully characterized their phenotypes, and were able to define a recognizable intellectual disability syndrome. In parallel, characterization of a chemically mutagenized mouse line that displays features similar to those of human patients with β-catenin mutations enabled us to investigate the consequences of β-catenin dysfunction through development and into adulthood. The mouse mutant, designated batface (Bfc), carries a Thr653Lys substitution in the C-terminal armadillo repeat of β-catenin and displayed a reduced affinity for membrane-associated cadherins. In association with this decreased cadherin interaction, we found that the mutation results in decreased intrahemispheric connections, with deficits in dendritic branching, long-term potentiation, and cognitive function. Our study provides in vivo evidence that dominant mutations in β-catenin underlie losses in its adhesion-related functions, which leads to severe consequences, including intellectual disability, childhood hypotonia, progressive spasticity of lower limbs, and abnormal craniofacial features in adults.

Mental health needs in adolescents with intellectual disabilities: cross-sectional survey of a service sample.

PubMed

Hassiotis, A; Turk, J

Little research has been conducted on the mental health needs of adolescents with intellectual disability, despite the severity and rates of such needs being high throughout childhood and in adulthood. We have investigated the prevalence and predictors of mental health needs and service use in adolescents with intellectual disabilities. Service-based sample (n = 75) in one catchment area. Individual assessments were carried out. The main outcome was the presence of mental health needs measured by the Developmental Behaviour Checklist. Prevalence of mental health needs increased from 51% as reported by parents to 67% as judged by clinical interviews. Caseness was associated with low adaptive functioning, diagnosis of autism and family history of mental illness. High scores on parent reports of participant mental ill-health showed negative correlations with adaptive functioning scores. Most individuals were in receipt of social and health care. Half of the participants had sought help for mental health needs. Almost half of those receiving medication were on psychiatric medication. Adolescents with intellectual disabilities may have considerable mental health problems which are functionally impairing yet frequently unidentified and hence untreated. Identification of those at risk and undertaking of a comprehensive needs assessment are essential to maximize potential and quality of life and to reduce further deficits and social exclusion. © 2012 Blackwell Publishing Ltd.

Intellectual disability is a common neurodevelopmental disorder characterized by impaired intellectual and adaptive functioning. Both environmental insults and genetic defects contribute to the etiology of intellectual disability. Copy number variations of SORBS2 have been linked to intellectual disability. However, the neurobiological function of SORBS2 in the brain is unknown. The SORBS2 gene encodes ArgBP2 (Arg/c-Abl kinase binding protein 2) protein in non-neuronal tissues and is alternatively spliced in the brain to encode nArgBP2 protein. We found nArgBP2 colocalized with F-actin at dendritic spines and growth cones in cultured hippocampal neurons. In the mouse brain, nArgBP2 was highly expressed in the cortex, amygdala, and hippocampus, and enriched in the outer one-third of the molecular layer in dentate gyrus. Genetic deletion of Sorbs2 in mice led to reduced dendritic complexity and decreased frequency of AMPAR-miniature spontaneous EPSCs in dentate gyrus granule cells. Behavioral characterization revealed that Sorbs2 deletion led to a reduced acoustic startle response, and defective long-term object recognition memory and contextual fear memory. Together, our findings demonstrate, for the first time, an important role for nArgBP2 in neuronal dendritic development and excitatory synaptic transmission, which may thus inform exploration of neurobiological basis of SORBS2 deficiency in intellectual disability. SIGNIFICANCE STATEMENT Copy number variations of the SORBS2 gene are linked to intellectual disability, but the neurobiological mechanisms are unknown. We found that nArgBP2, the only neuronal isoform encoded by SORBS2, colocalizes with F-actin at neuronal dendritic growth cones and spines. nArgBP2 is highly expressed in the cortex, amygdala, and dentate gyrus in the mouse brain. Genetic deletion of Sorbs2 in mice leads to impaired dendritic complexity and reduced excitatory synaptic transmission in dentate gyrus granule cells, accompanied by behavioral deficits in acoustic startle response and long-term memory. This is the first study of Sorbs2 function in the brain, and our findings may facilitate the study of neurobiological mechanisms underlying SORBS2 deficiency in the development of intellectual disability.

To explore internal consistency and correlations between perceived ability, performance and perceived importance in a preliminary selection of self-reported items representing the activity/participation component of the International Classification of Functioning, Disability and Health (ICF). Structured interview study. Fifty-five Swedish adolescents and adults with a mild intellectual disability. Questions about perceived ability, performance and perceived importance were asked on the basis of a 3-grade Likert-scale regarding each of 68 items representing the 9 ICF domains of activity/participation. Internal consistency for perceived ability (Cronbach's alpha for all 68 items): 0.95 (values for each domain varied between 0.57 and 0.85), for performance: 0.86 (between 0.27 and 0.66), for perceived importance: 0.84 (between 0.27 and 0.68). Seventy-two percent of the items showed correlations >0.5 (mean=0.59) for performance vs perceived importance, 41% >0.5 (mean=0.47) for perceived ability vs performance and 12% >0.5 (mean=0.28) for perceived ability vs perceived importance. Measures of performance and perceived importance may have to be based primarily on their estimated clinical relevance for describing aspects of the ICF participation concept. With a clinimetric approach, parts of the studied items and domains may be used to investigate factors related to different patterns and levels of participation, and outcomes of rehabilitation.

Autistic spectrum disorders are a group of neurological and developmental disorders associated with social, communication, sensory, behavioral and cognitive impairments, as well as restricted, repetitive patterns of behavior, activities, or interests.The aim of this study was a) to analyze QEEG findings of autistic patients and to compare the results with data base; and b) to introduce the calculation of spectrum weighted frequency (brain rate) as an indicator of general mental arousal in these patients. Results for Q-EEG shows generally increased delta-theta activity in frontal region of the brain. Changes in QEEG pattern appeared to be in a non-linear correlation with maturational processes.Brain rate measured in CZ shows slow brain activity (5. 86) which is significantly lower than normal and corresponds to low general mental arousal.Recent research has shown that autistic disorders have as their basis disturbances of neural connectivity. Neurofeedback seems capable of remediating such disturbances when these data are considered as part of treatment planning. Prognosis of this pervasive disorder depends on the intellectual abilities: the better intellectual functioning, the possibilities for life adaptation are higherQEEG shows generally increased delta-theta activity in frontal region of the brain which is related to poor cognitive abilities.Brain rate measured in CZ shows slow brain activity related to under arousal.Pharmacotherapy combined with behavior therapy, social support and especially neurofeedback technique promise slight improvements.

Effects of video-feedback intervention on harmonious parent-child interaction and sensitive discipline of parents with intellectual disabilities: A randomized controlled trial.

2018-03-01

This study tested whether video-feedback intervention based on attachment and coercion theory increased harmonious parent-child interaction and sensitive discipline of parents with mild intellectual disabilities or borderline intellectual functioning. Observer ratings of video-recorded structured interaction tasks at home formed pretest, post-test, and 3-month follow-up outcome data in a randomized controlled trial with 85 families. Repeated measures analyses of variance and covariance were conducted to test for the intervention effect and possible moderation by IQ and adaptive functioning. The intervention effect on harmonious parent-child interaction was conditional on parental social adaptive behaviour at pretest, with lower adaptive functioning associated with stronger intervention benefit at post-test and follow-up compared to care as usual. Intervention effects were not conditional on parental IQ. Intervention effects for sensitive discipline were not found. Although the video-feedback intervention did not affect observed parenting for the average parent, it may benefit interaction between children and parents with lower parental adaptive functioning. © 2017 John Wiley & Sons Ltd.

Examination of the communication interface between students with severe to profound and multiple intellectual disability and educational staff during structured teaching sessions.

PubMed

Bunning, K; Smith, C; Kennedy, P; Greenham, C

2013-01-01

Individuals with severe to profound and multiple intellectual disability (S-PMID) tend to function at the earlier stages of communication development. Variable and highly individual means of communicating may present challenges to the adults providing support in everyday life. The current study aimed to examine the communication interface between students with S-PMID and educational staff. An in-depth, observational study of dyadic interaction in a class within the secondary part of a special school was conducted. The designated educational level was Key Stage 3 under the National Curriculum of England, which is typically for children from age 11 to 14 years attending a state school. There were four student-teacher dyads in the class. The students had multiple impairments with severely limited communication skills. Video capture of dyadic interaction was conducted during five English lessons and sampled to 2.5 min per dyad per lesson. The video footage was transcribed into standard orthography, detailing the vocal and non-vocal aspects. A coding framework guided by the principles of structural-functional linguistics was used to determine the nature of dyadic interaction, comprising linguistic moves, functions and communicative modalities. The relative contributions of student and teacher to the interaction were examined. Significant differences were found between the students and educational staff on the majority of the measures. The teachers dominated the interaction, occupying significantly more turns than the students. Teacher turns contained significantly more initiations and follow-up moves than the students, who used more response moves. Teacher communication mainly served the functions of requesting and information giving. Feedback and scripted functions were also significantly greater among teacher turns, with only limited occurrence among the students. Self- or shared-expression was greatest among the students. The modalities of speech, touch, singing and objects were used by the teachers for the purpose of communication, whereas vocalisation and gesture were used by the students. Despite differences in the availability of communication skills, both student and teacher were able to make their respective contributions to the interaction during classroom activity. Features of the student-teacher interface retained critical features seen in studies of more able individuals with intellectual disability. Scaffolding provided by teachers appears to be relevant to the communicative contributions of individuals functioning at the earliest stages of communication. The coding framework based on structural-functional linguistics provides some new potential for examining and enhancing the communication interface between individuals with S-PMID and the people who support them. © 2011 The Authors.

Conflict control of children with different intellectual levels: an ERP study.

PubMed

Liu, Tongran; Xiao, Tong; Shi, Jiannong; Zhao, Daheng; Liu, Jizhong

2011-02-25

Conflict control is an important cognitive ability in human behavioral regulation. The Eriksen flanker task was employed to explore the neural correlation between conflict control and intelligence with the aid of event-related potential (ERP) techniques. Two groups of early adolescents with different intellectual levels participated in the current study (an intellectually gifted group of 20 children vs. an intellectually average group of 21 children, with mean scores of 43 vs. 35.7 in Cattell's Culture Fair Test, respectively). Behavioral results indicate that the gifted children had better conflict control performances, with increased accuracy and faster response speeds than the intellectually average children. Electrophysiological results further show that the gifted children had more efficient N2 activations during conflict monitoring processing, faster P3 responses over frontal regions, and stronger P3 activations over central-parietal regions during attentional control processing. The difference waveform analysis showed that the gifted children had the weakest N2d activations when elicited by multiple conflicts. N2d amplitudes can be used to distinguish a stimulus conflict from a response conflict, and P3d amplitudes can be used to separate multiple conflicts from a single conflict. The results support the neural efficiency hypothesis of intelligence and shed light on the close relationship between conflict control ability and human intelligence.

Relating children's attentional capabilities to intelligence, memory, and academic achievement: a test of construct specificity in children with asthma.

PubMed

Annett, Robert D; Bender, Bruce G; Gordon, Michael

2007-01-01

The relationship between attention, intelligence, memory, achievement, and behavior in a large population (N = 939) of children without neuropsychologic problems was investigated in children with mild and moderate asthma. It was hypothesized that different levels of children's attentional capabilities would be associated with different levels of intellectual, memory, and academic abilities. Children ages 6-12 at the eight clinical centers of the Childhood Asthma Management Program (CAMP) were enrolled in this study. Standardized measures of child neuropsychological and behavioral performance were administered to all participants, with analyses examining both the developmental trajectory of child attentional capabilities and the associations between Continuous Performance Test (CPT) scores and intellectual functioning, and measures of memory, academic achievement, and behavioral functioning. Findings demonstrated that correct responses on the CPT increase significantly with age, while commission errors decrease significantly with age. Performance levels on the CPT were associated with differences in child intellectual function, memory, and academic achievement. Overall these findings reveal how impairments in child attention skills were associated with normal levels of performance on measures of children's intelligence, memory, academic achievement, and behavioral functioning, suggesting that CPT performance is a salient marker of brain function.

Visual perception and frontal lobe in intellectual disabilities: a study with evoked potentials and neuropsychology.

Muñoz-Ruata, J; Caro-Martínez, E; Martínez Pérez, L; Borja, M

2010-12-01

Perception disorders are frequently observed in persons with intellectual disability (ID) and their influence on cognition has been discussed. The objective of this study is to clarify the mechanisms behind these alterations by analysing the visual event related potentials early component, the N1 wave, which is related to perception alterations in several pathologies. Additionally, the relationship between N1 and neuropsychological visual tests was studied with the aim to understand its functional significance in ID persons. A group of 69 subjects, with etiologically heterogeneous mild ID, performed an odd-ball task of active discrimination of geometric figures. N1a (frontal) and N1b (post-occipital) waves were obtained from the evoked potentials. They also performed several neuropsychological tests. Only component N1a, produced by the target stimulus, showed significant correlations with the visual integration, visual semantic association, visual analogical reasoning tests, Perceptual Reasoning Index (Wechsler Intelligence Scale for Children Fourth Edition) and intelligence quotient. The systematic correlations, produced by the target stimulus in perceptual abilities tasks, with the N1a (frontal) and not with N1b (posterior), suggest that the visual perception process involves frontal participation. These correlations support the idea that the N1a and N1b are not equivalent. The relationship between frontal functions and early stages of visual perception is revised and discussed, as well as the frontal contribution with the neuropsychological tests used. A possible relationship between the frontal activity dysfunction in ID and perceptive problems is suggested. Perceptive alteration observed in persons with ID could indeed be because of altered sensory areas, but also to a failure in the frontal participation of perceptive processes conceived as elaborations inside reverberant circuits of perception-action. © 2010 The Authors.

Mucopolysaccharidosis type III (MPS III, Sanfilippo syndrome) is a lysosomal storage disorder, caused by a deficiency in one of four enzymes involved in the catabolism of the glycosaminoglycan heparan sulphate. It is a degenerative disorder, with a progressive decline in children's intellectual and physical functioning. There is currently no cure for the disorder. To date there is a paucity of research on how this disorder impacts parents psychological functioning. Specifically, research in the area has failed to employ adequate control groups to assess if the impact of this disorder on parents psychological functioning differs from parenting a child with intellectual disability (ID). The current study examined child behaviour and parental psychological functioning in 23 parents of children with MPS III and 23 parents of children with ID. Parents completed postal questionnaires about their child's behaviour and abilities and their own psychological functioning. Parents of children with MPS III reported fewer behavioural difficulties as their child aged, more severe level of intellectual disability, and similar levels of perceived social support, coping techniques, stress, anxiety and depression levels as parents of children with ID. Both groups of parents scored above the clinical cut off for anxiety and depression. Parents of children with MPS III rated themselves as significantly less future-orientated and goal directed than parents of children with ID. Services should develop support packages for parents of children with MPS III that incorporate an understanding of the unique stressors and current-difficulty approach of this population. Future research should examine gender differences between parental psychological functioning, using mixed qualitative and quantitative approaches, and utilise matched developmental level and typically developing control groups.

Intellectual disability (ID) is characterized by limitation in intellectual function and adaptive behavior, with onset in childhood. Frequent identifiable causes of ID originate from chromosomal imbalances. During the last years, array-CGH has successfully contributed to improve the diagnostic detection rate of genetic abnormalities in patients with ID. Most array-CGH studies focused on patients with moderate or severe intellectual disability. Studies on genetic etiology in children with mild intellectual disability (ID) are very rare. We performed array-CGH analysis in 66 children with mild intellectual disability assessed in a population-based study and for whom no genetic etiology was identified. We found one or more copy number variations (CNVs) in 20 out of 66 (~30 %) patients with a mild ID. In eight of them (~12 %), the CNVs were certainly responsible for the phenotype and in six they were potentially pathogenic for ID. Altogether, array-CGH helped to determine the etiology of ID in 14 patients (~21 %). Our results underscore the clinical relevance of array-CGH to investigate the etiology of isolated idiopathic mild ID in patients or associated with even subtle dysmorphic features or congenital malformations.

School dysfunction is observed in youths with autism spectrum disorder (ASD), but the factors moderating their school dysfunction have not been well explored. This study investigated school functions in youths with ASD in Taiwan, stratified by personal characteristics including demographics, ASD subtypes, intelligence profiles, and the presence of attention-deficit hyperactivity disorder (ADHD). We recruited 160 youths (aged 6-18 years, 87.5% boys) with a clinical diagnosis of ASD and 160 age and gender-matched typically developing (TD) youths. Their parents received a semi-structured psychiatric interview for their ASD and ADHD diagnoses and reported their school functions. Youths with ASD were further grouped into low-functioning autism (LFA, ASD with intellectual disability and developmental language delay, n = 44), high-functioning autism (HFA, ASD with no intellectual disability, n = 55) and Asperger's syndrome (AS, ASD with neither language delay nor intellectual disability, n = 61). Compared to TD, ASD had worse school functions in the domains of academic performance, attitude toward schoolwork, social interaction, and behavioral problems except for no academic differences from TD in HFA and ASD without ADHD. Subgroup analysis revealed that HFA and AS had better academic performance but showed worse attitude toward school than LFA. Comorbidity of ADHD negatively impacted all domains of school functions. Besides autistic and ADHD symptoms, oppositional symptoms, lower intelligence, older age, and female gender in youths also predicted school dysfunction. Although youths with ASD have school dysfunction in several domains, this study specifically addresses the role of intelligence and comorbid ADHD on their school dysfunction. Autism Res 2018, 11: 857-869. © 2018 International Society for Autism Research, Wiley Periodicals, Inc. Impaired school functions varied in ASD youths with different characteristics. Youths with autism spectrum disorder (ASD) encounter varying levels and domains of impaired performance at schools, such as lower academic performance, negative attitude toward school work, fewer reciprocal friendships, and more behavioral problems. Our results indicate that ASD youths without intellectual disability had better academic performance, but worse attitude toward school than those with intellectual disability. Co-occurrence with ADHD is associated with school dysfunction. In summary, intelligence and comorbid ADHD influences several domains of school functions. © 2018 International Society for Autism Research, Wiley Periodicals, Inc.

Investigations around ageing with an intellectual disability have increased substantially in the past three decades. A research gap continued to exist regarding the detection of ageing issues in this cohort of people, particularly in rural areas where access to specialist support continued to be limited. The purpose of this study was to identify the main signs of ageing in rural people with intellectual disabilities. A multi-round Delphi design was used to examine what signs of ageing were observed by disability support staff, who assisted people with intellectual disability. The project was conducted across nine of the ten rural regions (as defined by the government funding body) in New South Wales (NSW). There were 31 participants representing 14 non-government organisations. The group was composed of 26 women and 5 men, with a mean age of 47 years, who averaged 10-year experience with people with intellectual disabilities. The objective was to gain the direct input of rurally based disability workers to identify the main signs of ageing in people with intellectual disabilities. Thirty-two specific signs of ageing, including emerging mental health issues, grief, loss of identity and aggression, were identified. A thematic analysis indicated two main categories: mental/emotional functioning and physical functioning. When carers have the information and skills needed to identify the main signs of ageing, they can more accurately recognise and address potential problems in a timely manner. Such understandings have the potential to reduce premature admissions to residential aged-care. © 2016 National Rural Health Alliance Inc.

The aim of the study was to define the intellectual profile of Polish children suffering from autism. Our study was based on the results of previous research, mostly conducted in English-speaking countries. Although these earlier studies documented the intellectual profile of an autistic child, they also identified some discrepancies. Therefore, we decided to complement the discussion on autism with our data on intellectual functioning of autistic Polish children examined with a translated version of the intelligence test. The study followed a matching design. From among 191 children with autism and 1 400 without this diagnosis, we selected 34 pairs based on gender and age, and not differing by more than 10 points in terms of intelligence quotient. The intellectual profile of the studied children was determined with the WISC-R scale. As expected, the intellectual profile of children with autism proved more variable than that of healthy controls. Children with autism scored lower on "Comprehension" scale and (at a threshold of statistical significance) on "Object assembly" scale, and achieved higher results on "Information" and "Block design" scales. The results of our study confirmed the most typical observations from previous research conducted among an English-speaking population of autistic children. Polish autistic children did not differ significantly in terms of their quotients of verbal and non-verbal intelligence. However, the intellectual profile of autistic children showed higher variance compared to normally developing controls. Children with autism were more likely to score the lowest in the "Comprehension" subtest and the highest in the "Block design" subtest.

Although “intellectual disability” has widely replaced the term “mental retardation”, the debate as to whether this entity should be conceptualized as a health condition or as a disability has intensified as the revision of the World Health Organization (WHO)’s International Classification of Diseases (ICD) advances. Defining intellectual disability as a health condition is central to retaining it in ICD, with significant implications for health policy and access to health services. This paper presents the consensus reached to date by the WHO ICD Working Group on the Classification of Intellectual Disabilities. Literature reviews were conducted and a mixed qualitative approach was followed in a series of meetings to produce consensus-based recommendations combining prior expert knowledge and available evidence. The Working Group proposes replacing mental retardation with intellectual developmental disorders, defined as “a group of developmental conditions characterized by significant impairment of cognitive functions, which are associated with limitations of learning, adaptive behaviour and skills”. The Working Group further advises that intellectual developmental disorders be incorporated in the larger grouping (parent category) of neurodevelopmental disorders, that current subcategories based on clinical severity (i.e., mild, moderate, severe, profound) be continued, and that problem behaviours be removed from the core classification structure of intellectual developmental disorders and instead described as associated features.

The study presents neuropsychiatric profiles of children aged 11 with autism spectrum disorder, assessed before 4.5 years, and after interventions. The original group comprised a community sample of 208 children with ASD. Parents of 128 participated-34 with average intellectual function, 36 with borderline intellectual function and 58 with intellectual disability. They were interviewed using the Autism-Tics, AD/HD and other Comorbidities interview. Criteria for a clinical/subclinical proxy of ASD were met by 71, 89 and 95 %, respectively. Criteria for at least one of ASD, AD/HD, Learning disorder or Developmental Coordination Disorder were met by 82, 94 and 97 %. More than 90 % of children with a preschool diagnosis of ASD have remaining neuropsychiatric problems at 11, despite early intervention.

Rescue of Learning and Memory Deficits in the Human Nonsyndromic Intellectual Disability Cereblon Knock-Out Mouse Model by Targeting the AMP-Activated Protein Kinase-mTORC1 Translational Pathway.

A homozygous nonsense mutation in the cereblon ( CRBN ) gene results in autosomal recessive, nonsyndromic intellectual disability that is devoid of other phenotypic features, suggesting a critical role of CRBN in mediating learning and memory. In this study, we demonstrate that adult male Crbn knock-out ( Crbn KO ) mice exhibit deficits in hippocampal-dependent learning and memory tasks that are recapitulated by focal knock-out of Crbn in the adult dorsal hippocampus, with no changes in social or repetitive behavior. Cellular studies identify deficits in long-term potentiation at Schaffer collateral CA1 synapses. We further show that Crbn is robustly expressed in the mouse hippocampus and Crbn KO mice exhibit hyperphosphorylated levels of AMPKα (Thr172). Examination of processes downstream of AMP-activated protein kinase (AMPK) finds that Crbn KO mice have a selective impairment in mediators of the mTORC1 translation initiation pathway in parallel with lower protein levels of postsynaptic density glutamatergic proteins and higher levels of excitatory presynaptic markers in the hippocampus with no change in markers of the unfolded protein response or autophagy pathways. Acute pharmacological inhibition of AMPK activity in adult Crbn KO mice rescues learning and memory deficits and normalizes hippocampal mTORC1 activity and postsynaptic glutamatergic proteins without altering excitatory presynaptic markers. Thus, this study identifies that loss of Crbn results in learning, memory, and synaptic defects as a consequence of exaggerated AMPK activity, inhibition of mTORC1 signaling, and decreased glutamatergic synaptic proteins. Thus, Crbn KO mice serve as an ideal model of intellectual disability to further explore molecular mechanisms of learning and memory. SIGNIFICANCE STATEMENT Intellectual disability (ID) is one of the most common neurodevelopmental disorders. The cereblon ( CRBN ) gene has been linked to autosomal recessive, nonsyndromic ID, characterized by an intelligence quotient between 50 and 70 but devoid of other phenotypic features, making cereblon an ideal protein for the study of the fundamental aspects of learning and memory. Here, using the cereblon knock-out mouse model, we show that cereblon deficiency disrupts learning, memory, and synaptic function via AMP-activated protein kinase hyperactivity, downregulation of mTORC1, and dysregulation of excitatory synapses, with no changes in social or repetitive behaviors, consistent with findings in the human population. This establishes the cereblon knock-out mouse as a model of pure ID without the confounding behavioral phenotypes associated with other current models of ID.

We studied a group of individuals with elevated urinary excretion of 3-methylglutaconic acid, neutropenia that can develop into leukemia, a neurological phenotype ranging from nonprogressive intellectual disability to a prenatal encephalopathy with progressive brain atrophy, movement disorder, cataracts, and early death. Exome sequencing of two unrelated individuals and subsequent Sanger sequencing of 16 individuals with an overlapping phenotype identified a total of 14 rare, predicted deleterious alleles in CLPB in 14 individuals from 9 unrelated families. CLPB encodes caseinolytic peptidase B homolog ClpB, a member of the AAA+ protein family. To evaluate the relevance of CLPB in the pathogenesis of this syndrome, we developed a zebrafish model and an in vitro assay to measure ATPase activity. Suppression of clpb in zebrafish embryos induced a central nervous system phenotype that was consistent with cerebellar and cerebral atrophy that could be rescued by wild-type, but not mutant, human CLPB mRNA. Consistent with these data, the loss-of-function effect of one of the identified variants (c.1222A>G [p.Arg408Gly]) was supported further by in vitro evidence with the mutant peptides abolishing ATPase function. Additionally, we show that CLPB interacts biochemically with ATP2A2, known to be involved in apoptotic processes in severe congenital neutropenia (SCN) 3 (Kostmann disease [caused by HAX1 mutations]). Taken together, mutations in CLPB define a syndrome with intellectual disability, congenital neutropenia, progressive brain atrophy, movement disorder, cataracts, and 3-methylglutaconic aciduria.

Impact of the Educational Boost Your Brain and Memory Program Among Senior Living Residents.

PubMed

Nicholson, Roscoe; O'Brien, Catherine

2017-12-01

This random assignment waitlist control intervention study examined an implementation of the educational Boost Your Brain and Memory cognitive fitness intervention in 12 senior living organizations. Older adult participants ( n = 166) completed measures of brain health knowledge, use of memory techniques, physical and intellectual activity, and mindfulness, at baseline and after the intervention group's completion of the course. Changes in knowledge scores and in self-reported physical and intellectual activity increased significantly more for intervention participants than for waitlist controls at the conclusion of the course. There were no significant changes between the groups in mindfulness or use of memory techniques. This suggests that in senior living settings Boost Your Brain and Memory is effective in educating participants about brain healthy behaviors and in motivating behavioral change in the areas of physical and intellectual activity.

Survivors of pediatric brain tumors and acute lymphoblastic leukemia (ALL) are at increased risk for neurocognitive deficits, but few empirically supported treatment options exist. We examined the feasibility and preliminary efficacy of a home-based, computerized working memory training program, CogmedRM, with survivors of childhood cancer. Survivors of brain tumors or ALL (n = 20) with identified deficits in attention and/or working memory were randomized to either the success-adapted computer intervention or a non-adaptive, active control condition. Specifically, children in the adaptive condition completed exercises that became more challenging with each correct trial, whereas those in the non-adaptive version trained with exercises that never increased in difficulty. All participants were asked to complete 25 training sessions at home, with weekly, phone-based coaching support. Brief assessments were completed pre-intervention and post-intervention; outcome measures included both performance-based and parent-report measures of working memory and attention. Eighty-five percent of survivors were compliant with the intervention, with no adverse events reported. After controlling for baseline intellectual functioning, survivors who completed the intervention program evidenced significant post-training improvements in their visual working memory and in parent-rated learning problems compared with those in the active control group. No differences in verbal working memory functioning were evident between groups, however. Home-based, computerized cognitive training demonstrates good feasibility and acceptability in our sample. Children with higher intellectual functioning at baseline appeared to benefit more from the training, although further study is needed to clarify the strength, scope, and particularly the generalizability of potential treatment effects.

There is limited large-scale empirical research into the working lives of adults who have an autism spectrum disorder with no co-occurring intellectual disability. Drawing on data from a national survey, this report describes the employment activities and experiences of 130 adults with Asperger's Disorder (AD) and high functioning autism (HFA) in Australia. Outcome measures include current occupation; occupational skill level and alignment with educational attainment; type of job contract; hours of work; support received to find work; support received in the workplace; and positive and negative experiences of employment. The findings confirm and expand upon existing evidence that adults with AD and HFA, despite their capacity and willingness to work, face significant disadvantages in the labour market and a lack of understanding and support in employment settings.

The bioethicist as public intellectual.

PubMed

Parsi, Kayhan P; Geraghty, Karen E

2004-01-01

Public intellectuals have long played a role in American culture, filling the gap between the academic elite and the educated public. According to some commentators, the role of the public intellectual has undergone a steady decline for the past several decades, being replaced by the academic expert. The most notable cause of this decline has been both the growth of the academy in the twentieth century,which has served to concentrate intellectual activity within its confines, and the changing nature of the media, which has framed the way in which information is conveyed to the public. We argue that although bioethics has developed primarily within the academic tradition and utilized the role of expert when dealing with the public, bioethicists are well suited to don the mantle of the public intellectual. Indeed, because they address issues in medicine and science of great relevance for the general public, bioethicists have a duty to revitalize the tradition of public intellectuals as a necessary complement to the important, but narrower role of the expert.

Balance and motor impairments are most evident among inactive individuals with ID that might be particularly susceptible to a loss of basic functioning and further limit the person's autonomy in activities of daily living. The aim of the study was to assess the effect of a 12-week trampoline exercise intervention program on motor and balance ability of school aged children with intellectual disability (ID). Eighteen healthy schools aged children (mean age=10.3 ± 1.6 years) with moderate ID were assigned either to an experimental group (n=9) or a control group (n=9). The experiment group attended a 12 weeks trampoline training intervention program consisting of daily individualized 20-min sessions, while the control group followed the regular school schedule. Balance was assessed using three tasks of increased difficulty (double-leg stance with eyes opened or closed, and one-leg stance with eyes opened) performed while standing on an electronic pressure platform (EPS). Motor performance of all participants was tested using sit and reach test and long and vertical jump tests all derived from the Eurofit Test Battery of physical fitness. Trampoline intervention resulted in significant improvements of participants' performance in all motor and balance tests. In conclusion, trampoline training can be an effective intervention for improving functional outcomes and can be recommended as an alternative mode of physical activity programming for improving balance and motor performance. Furthermore, it also supports the idea that individuals with ID require enjoyable and interesting intervention programs such as the trampoline program used in this study so as to remain active and consequently to facilitate their overall development and promote a more active and healthier way of life.

WISC-IV Intellectual Profiles in Italian Children With Specific Learning Disorder and Related Impairments in Reading, Written Expression, and Mathematics.

PubMed

Poletti, Michele

2016-01-01

The fifth edition of theDiagnostic and Statistical Manual of Mental Disordersgrouped specific learning disabilities in the single diagnostic category of specific learning disorder (SLD), with specifiers for impairments in reading, written expression, and mathematics. This study aimed at investigating the intellectual profile, assessed with the fourth edition of theWechsler Intelligence Scale for Children(WISC-IV), of 172 children with a diagnosis of SLD, compared to 74 clinical referral controls. WISC-IV intellectual functioning in children with SLD was characterized by a significant discrepancy between general ability and cognitive proficiency (General Ability Index [GAI] > Cognitive Proficiency Index [CPI]), and worse performances on the Similarities, Digit Span, Letter-Number Sequencing, and Coding subtests, supporting models of multiple cognitive deficits at the basis of neurodevelopmental disorders as SLD. GAI was the best and more conservative measure provided by the WISC-IV to identify intellectual functioning in children with SLD, and the intellectual discrepancy between GAI and CPI could be considered a "cognitive sign" for the presence of SLD in a single diagnostic category. Cognitive deficits differed in subtypes of impairment (reading, written expression, and mathematics), supporting their distinction for empirical, educational, and rehabilitative purposes. These findings need further replication in larger samples and in comparison to typically developing children. © Hammill Institute on Disabilities 2014.

Histamine (HA) acts as a neurotransmitter in the brain, which participates in the regulation of many biological processes including inflammation, gastric acid secretion and neuromodulation. The enzyme histamine N-methyltransferase (HNMT) inactivates HA by transferring a methyl group from S-adenosyl-l-methionine to HA, and is the only well-known pathway for termination of neurotransmission actions of HA in mammalian central nervous system. We performed autozygosity mapping followed by targeted exome sequencing and identified two homozygous HNMT alterations, p.Gly60Asp and p.Leu208Pro, in patients affected with nonsyndromic autosomal recessive intellectual disability from two unrelated consanguineous families of Turkish and Kurdish ancestry, respectively. We verified the complete absence of a functional HNMT in patients using in vitro toxicology assay. Using mutant and wild-type DNA constructs as well as in silico protein modeling, we confirmed that p.Gly60Asp disrupts the enzymatic activity of the protein, and that p.Leu208Pro results in reduced protein stability, resulting in decreased HA inactivation. Our results highlight the importance of inclusion of HNMT for genetic testing of individuals presenting with intellectual disability. © The Author 2015. Published by Oxford University Press.

The relationship between cognitive dysfunction and coping abilities in schizophrenia.

Wilder-Willis, Kelly E; Shear, Paula K; Steffen, John J; Borkin, Joyce

2002-06-01

Cognitive dysfunction is a core feature of schizophrenia [Psychiatr. Clin. North Am., 16 (1993) 295; Psychopharmacology: The fourth generation of progress, Raven Press, New York (1995) 1171; Clinical Neuropsychology, Oxford University Press, New York (1993) 449] and is related to psychosocial functioning in this population [Am. J. Psychiatry, 153 (1996) 321]. It is unclear whether cognitive dysfunction is related to specific areas of functioning in schizophrenia, such as coping abilities. Individuals with schizophrenia have deficient coping skills, which may contribute to their difficulties dealing with stressors [Am. J. Orthopsychiatry, 62 (1992) 117; J. Abnorm. Psychol., 82 (1986) 189]. The current study examined the relationship between coping abilities and cognitive dysfunction in a community sample of individuals with schizophrenia. It was hypothesized that executive dysfunction and mnemonic impairments would be positively related to deficiencies in active coping efforts involving problem solving and self-initiation (e.g. advocating for oneself and others with mental illness and becoming involved in meaningful activities, such as work), independent of the contributions of the general intellectual deficits associated with the disorder and psychiatric symptoms. The results indicated that both executive dysfunction and mnemonic impairments were related to decreased usage of active coping mechanisms after controlling for general intellectual deficits. Further, recognition memory made independent contributions to the prediction of coping involving action and help seeking after controlling for the effects of negative symptoms. These findings suggest that individuals with schizophrenia may be less flexible in their use of coping strategies, which may in turn contribute to their difficulties in coping with mental illness and its consequences.

Animal models of intellectual disability: towards a translational approach

Intellectual disability is a prevalent form of cognitive impairment, affecting 2–3% of the general population. It is a daunting societal problem characterized by significant limitations both in intellectual functioning and in adaptive behavior as expressed in conceptual, social and practical adaptive skills. Intellectual disability is a clinically important disorder for which the etiology and pathogenesis are still poorly understood. Moreover, although tremendous progress has been made, pharmacological intervention is still currently non-existent and therapeutic strategies remain limited. Studies in humans have a very limited capacity to explain basic mechanisms of this condition. In this sense, animal models have been invaluable in intellectual disability investigation. Certainly, a great deal of the knowledge that has improved our understanding of several pathologies has derived from appropriate animal models. Moreover, to improve human health, scientific discoveries must be translated into practical applications. Translational research specifically aims at taking basic scientific discoveries and best practices to benefit the lives of people in our communities. In this context, the challenge that basic science research needs to meet is to make use of a comparative approach to benefit the most from what each animal model can tell us. Intellectual disability results from many different genetic and environmental insults. Taken together, the present review will describe several animal models of potential intellectual disability risk factors. PMID:21779723

The ubiquitin pathway is an enzymatic cascade including activating E1, conjugating E2, and ligating E3 enzymes, which governs protein degradation and sorting. It is crucial for many physiological processes. Compromised function of members of the ubiquitin pathway leads to a wide range of human diseases, such as cancer, neurodegenerative diseases, and neurodevelopmental disorders. Mutations in the thyroid hormone receptor interactor 12 (TRIP12) gene (OMIM 604506), which encodes an E3 ligase in the ubiquitin pathway, have been associated with autism spectrum disorder (ASD). In addition to autistic features, TRIP12 mutation carriers showed intellectual disability (ID). More recently, TRIP12 was postulated as a novel candidate gene for intellectual disability in a meta-analysis of published ID cohorts. However, detailed clinical information characterizing the phenotype of these individuals was not provided. In this study, we present seven novel individuals with private TRIP12 mutations including two splice site mutations, one nonsense mutation, three missense mutations, and one translocation case with a breakpoint in intron 1 of the TRIP12 gene and clinically review four previously published cases. The TRIP12 mutation-positive individuals presented with mild to moderate ID (10/11) or learning disability [intelligence quotient (IQ) 76 in one individual], ASD (8/11) and some of them with unspecific craniofacial dysmorphism and other anomalies. In this study, we provide detailed clinical information of 11 TRIP12 mutation-positive individuals and thereby expand the clinical spectrum of the TRIP12 gene in non-syndromic intellectual disability with or without ASD.

Children with intellectual disabilities show deficits in both reasoning ability and working memory (WM) that impact everyday functioning and academic achievement. In this study we investigated the feasibility of cognitive training for improving WM and non-verbal reasoning (NVR) ability in children with intellectual disability. Participants were randomized to a 5-week adaptive training program (intervention group) or non-adaptive version of the program (active control group). Cognitive assessments were conducted prior to and directly after training and 1 year later to examine effects of the training. Improvements during training varied largely and amount of progress during training predicted transfer to WM and comprehension of instructions, with higher training progress being associated with greater transfer improvements. The strongest predictors for training progress were found to be gender, co-morbidity, and baseline capacity on verbal WM. In particular, females without an additional diagnosis and with higher baseline performance showed greater progress. No significant effects of training were observed at the 1-year follow-up, suggesting that training should be more intense or repeated in order for effects to persist in children with intellectual disabilities. A major finding of this study is that cognitive training is feasible in this clinical sample and can help improve their cognitive performance. However, a minimum cognitive capacity or training ability seems necessary for the training to be beneficial, with some individuals showing little improvement in performance. Future studies of cognitive training should take into consideration how inter-individual differences in training progress influence transfer effects and further investigate how baseline capacities predict training outcome.

Autosomal-recessive non-syndromic intellectual disability (ARNS-ID) is an aetiologically heterogeneous disorder. Although little is known about the function of human cereblon (CRBN), its relationship to mild cognitive deficits suggests that it is involved in the basic processes of human memory and learning. We aim to identify the genetic cause of intellectual disability and self-mutilation in a consanguineous Saudi family with five affected members. Clinical whole-exome sequencing was performed on the proband patient, and Sanger sequencing was done to validate and confirm segregation in other family members. A missense variant (c. 1171T>C) in the CRBN gene was identified in five individuals with severe intellectual disability (ID) in a consanguineous Saudi family. The homozygous variant was co-segregating in the family with the phenotype of severe ID, seizures and self-mutilating behaviour. The missense mutation (p.C391R) reported here results in the replacement of a conserved cysteine residue by an arginine in the CULT (cereblon domain of unknown activity, binding cellular ligands and thalidomide) domain of CRBN, which contains a zinc-binding site. These findings thus contribute to a growing list of ID disorders caused by CRBN mutations, broaden the spectrum of phenotypes attributable to ARNS-ID and provide new insight into genotype-phenotype correlations between CRBN mutations and the aetiology of ARNS-ID.

French, Brigittine M

2004-01-01

This paper discusses the development Mayan linguistics as an authoritative field of knowledge in Guatemala. In particular, it links missionary linguists' and Maya linguists' activities with shifting nationalist agendas from the 1920s in to the late 1980s. It is argued that during the historical and intellectual moment that linguistics becomes an authoritative epistemology, phonetic analysis functions as a creative index that constitutes "expert" knowledge for particular semiotic and ideological reasons tied to competing versions of the Guatemalan imagined community.

We analyzed the role of a heterotrimeric G-protein, Gi2, in the development of the cerebral cortex. Acute knockdown of the α-subunit (Gαi2) with in utero electroporation caused delayed radial migration of excitatory neurons during corticogenesis, perhaps because of impaired morphology. The migration phenotype was rescued by an RNAi-resistant version of Gαi2. On the other hand, silencing of Gαi2 did not affect axon elongation, dendritic arbor formation or neurogenesis at ventricular zone in vivo. When behavior analyses were conducted with acute Gαi2-knockdown mice, they showed defects in social interaction, novelty recognition and active avoidance learning as well as increased anxiety. Subsequently, using whole-exome sequencing analysis, we identified a de novo heterozygous missense mutation (c.680C>T; p.Ala227Val) in the GNAI2 gene encoding Gαi2 in an individual with periventricular nodular heterotopia and intellectual disability. Collectively, the phenotypes in the knockdown experiments suggest a role of Gαi2 in the brain development, and impairment of its function might cause defects in neuronal functions which lead to neurodevelopmental disorders. © 2016 International Society for Neurochemistry.

Neurophysiological basis of creativity in healthy elderly people: a multiscale entropy approach.

Creativity, which presumably involves various connections within and across different neural networks, reportedly underpins the mental well-being of older adults. Multiscale entropy (MSE) can characterize the complexity inherent in EEG dynamics with multiple temporal scales. It can therefore provide useful insight into neural networks. Given that background, we sought to clarify the neurophysiological bases of creativity in healthy elderly subjects by assessing EEG complexity with MSE, with emphasis on assessment of neural networks. We recorded resting state EEG of 20 healthy elderly subjects. MSE was calculated for each subject for continuous 20-s epochs. Their relevance to individual creativity was examined concurrently with intellectual function. Higher individual creativity was linked closely to increased EEG complexity across higher temporal scales, but no significant relation was found with intellectual function (IQ score). Considering the general "loss of complexity" theory of aging, our finding of increased EEG complexity in elderly people with heightened creativity supports the idea that creativity is associated with activated neural networks. Results reported here underscore the potential usefulness of MSE analysis for characterizing the neurophysiological bases of elderly people with heightened creativity.

2017-09-01

The benefits of autonomy support with the general population have been demonstrated numerous times. However, little research has been conducted to verify if these benefits apply to people with special needs. The goal of the study was to examine whether autonomy support (AS) can foster the sense of autonomy of people with a mild intellectual disabilities (MIDs) and improve their experience while engaging in an important but unpleasant learning activity. This experiment compares the effects of two contexts: with and without AS. All participants (N = 51) had a mild intellectual disability and were recruited from rehabilitation centres. Compared to participants in the control group, participants in the AS group tended to experience greater autonomy satisfaction and tended to perceive more value to the activity. They were also significantly more engaged in it, and they experienced a steeper decrease in anxiety over time. This study suggests that the benefits of AS extend to individuals with mild intellectual disability. © 2016 John Wiley & Sons Ltd.

Exploitation of rights from the US space program by NASA: Review of the process

The legal environment, and some observations on the policies, procedures, and practices developed and instituted by NASA with regard to the treatment of intellectual property rights arising out of NASA support, are presented. The allocation, protection, and exercise (or exploitation) of such rights are considered. Focus is on the exercise (or exploitation) of intellectual property rights in a manner that provides an incentive to achieve beneficial or commercial use by the private sector of technology resulting from the U.S. space program. While some emphasis is on matters unique to the U.S. space program, many of the policies, procedures, and practices supported research and development activities. The process of making the results of U.S. government supported research and development activities available to the private sector for beneficial or commercial use, whether or not subject to intellectual property rights protection, is commonly known as technology transfer. Consequently, the consideration of intellectual property rights is in the context of the broader technology transfer objectives of NASA.

The NONO protein has been characterized as an important transcriptional regulator in diverse cellular contexts. Here we show that loss of NONO function is a likely cause of human intellectual disability and that NONO-deficient mice have cognitive and affective deficits. Correspondingly, we find specific defects at inhibitory synapses, where NONO regulates synaptic transcription and gephyrin scaffold structure. Our data identify NONO as a possible neurodevelopmental disease gene and highlight the key role of the DBHS protein family in functional organization of GABAergic synapses.

Social support and intellectual disabilities: a comparison between social networks of adults with intellectual disability and those with physical disability.

PubMed

Lippold, T; Burns, J

2009-05-01

Social support has been identified as a major protective factor in preventing mental health problems and also as a major contributor to quality of life. People with intellectual disabilities (ID) have been identified as having limited social support structures. Interventions have been focused on promoting their social presence and integration. However, previous studies have shown that this does not always lead to the formation of social relationships. To date few studies have looked at how having an ID leads to impoverished social networks. This study aimed to do this by contrasting the social relationships of people with physical disabilities (PD) and people with ID. Two groups of participants were recruited; 30 people with mild ID and 17 people with PD. Social and functional support networks were assessed, in addition to life experiences. Between and within group differences were then explored statistically. Adults with ID had more restricted social networks than PD, despite being involved in more activities. Social support for adults with ID was mainly provided by family and carers and few relationships with non-disabled people were identified. In contrast adults with PD had larger social networks than had been reported in the mainstream literature and had a balance of relationships with disabled and non-disabled people. The results suggest that there are additional processes attached to having an ID, which lead to continued impoverished lifestyles. The findings also endorse other work that suggests being physically integrated and engaged in a wide range of activities does not guarantee good social and emotional support.

Treating Individuals With Intellectual Disabilities and Challenging Behaviors With Adapted Dialectical Behavior Therapy

2013-01-01

Approximately one third of adults with intellectual and developmental disabilities have emotion dysregulation and challenging behaviors (CBs). Although research has not yet confirmed that existing treatments adequately reduce CBs in this population, dialectical behavior therapy (DBT) holds promise, as it has been shown to effectively reduce CBs in other emotionally dysregulated populations. This longitudinal single-group pilot study examined whether individuals with impaired intellectual functioning would show reductions in CBs while receiving standard DBT individual therapy used in conjunction with the Skills System (DBT-SS), a DBT emotion regulation skills curriculum adapted for individuals with cognitive impairment. Forty adults with developmental disabilities (most of whom also had intellectual disabilities) and CBs, including histories of aggression, self-injury, sexual offending, or other CBs, participated in this study. Changes in their behaviors were monitored over 4 years while in DBT-SS. Large reductions in CBs were observed during the 4 years. These findings suggest that modified DBT holds promise for effectively treating individuals with intellectual and developmental disabilities. PMID:23914278

The impact of behavioural executive functioning and intelligence on math abilities in children with intellectual disabilities.

Little is known about the role of behavioural executive functioning (EF) skills and level of intelligence (IQ) on math abilities in children with mild to borderline intellectual disabilities. Teachers of 63 children attending a school for special education (age: 10 to 13 years; IQ: 50 to 85) filled out a Behaviour Rating Inventory for Executive Function for each student. Furthermore, students took a standardised national composite math test and a specific math test on measurement and time problems. Information on level of intelligence was gathered through school records. Multiple regression analyses were performed to test direct, moderating and mediating effects of EF and IQ on math performance. Behavioural problems with working memory and flexibility had a direct negative effect on math outcome, while concurrently, level of intelligence had a positive effect. The effect of IQ on math skills was moderated by problems with inhibition: in children with a clinical level of inhibition problems, there was no effect of level of intelligence on math performance. Findings suggest that in students with mild to borderline intellectual disabilities and math difficulties, it is important to address their strengths and weaknesses with respect to EF and adjust instruction and remedial intervention accordingly. © 2016 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

Can cerebral MRI at age 1 year predict motor and intellectual outcomes in very-low-birthweight children?

1998-04-01

This follow-up study reports on cerebral MRI findings in 20 very-low-birthweight (VLBW) infants without disabilities at age 1 year in relation to motor, intellectual, and perceptual function at age 6 years. MRI findings, anthropometrics, and Bayley Scales of Infant Development scores at age 1 year as predictors of psychomotor status at age 6 years are also evaluated and compared. Outcome parameters were the Peabody Developmental Motor Scales and the Wechsler Preschool and Primary Scale of Intelligence. The results show that infants with myelin hyperintensities including the centrum semiovale or with occipital hyperintensities with associated ventricular dilatation at age 1 scored lower on the Peabody Gross Motor Locomotion Scale at age 6 than infants with normal myelination or with isolated occipital hyperintensities. This may indicate damage to motor fibers caused by perinatal periventricular leukomalacia. No relation was found between abnormal MRI findings at age 1 and later fine motor, intellectual, and perceptual function. Comparing different age 1-year predictors, an abnormality score defined by MRI was used as an independent predictor of gross motor locomotion function at age 6 years. However, the Bayley Mental Development Index scores and weight at age 1 were more important predictors of later motor and intellectual outcome, respectively, than MRI findings. It is recommended that cerebral MRI should not be used routinely to examine VLBW infants without disabilities at 1 year of age.

2013-08-01

Thirty-six children between 9 and 12 years of age were invited to share their ideas on how to socially include classmates with learning or intellectual disabilities at school. Participants generated 80 strategies which were categorized into seven major themes. Thematic categories focused on the need for teachers to intervene in academic and social situations, child-to-child instructional strategies, being supportive, focusing on similarities between children with and without disabilities, modelling appropriate behaviors and intervening in negative interactions, structured inclusive activities, and noninclusive activities. Participants were aware of the challenges experienced by classmates with disabilities, and recognized the need to work with classmates and teachers towards the social inclusion of children with intellectual and learning disabilities. Educational implications are addressed.

Findings may reflect better daily functioning among Black youth with ASD and/or cultural differences in parent response to questionnaires. Regardless, these findings raise concern about the sensitivity of commonly used measures for Black children with ASD and the impact of culture on daily functioning and symptom manifestation.

Aciego, Ramón; García, Lorena; Betancort, Moisés

2012-07-01

This paper examines the benefits of regularly playing chess for the intellectual and social-emotional enrichment of a group of 170 schoolchildren from 6-16 years old. It is based on a quasi-experimental design, where the independent variable was the extracurricular activity of chess (n = 170) versus extracurricular activities of soccer or basketball (n = 60). The dependent variable was intellectual and socio-affective competence, which was measured by an IQ test (WISC-R), a self-report test (TAMAI) and a hetero-report questionnaire (teacher-tutor's criterion) applied at the beginning and the end of the academic year. In contrast to the comparison group, it was found that chess improves cognitive abilities, coping and problem-solving capacity, and even socioaffective development of children and adolescents who practice it. The results are modulated, particularly in the area socioaffective, by the personal profile of students who choose practice this activity.

'It's our everyday life' - The perspectives of persons with intellectual disabilities in Norway.

Witsø, Aud Elisabeth; Hauger, Brit

2018-01-01

This study illuminates how adults with intellectual disabilities understand and describe their everyday life and its shortcomings when it comes to equal rights in the context of Norwegian community living. An inclusive research design, including nine persons with mild intellectual disability, two university researchers and two intellectual disability nurses from the municipality, was undertaken. An inductive thematic analysis of data identified three key themes: everyday life - context, rhythm and structure, social participation and staff - an ambiguous part of everyday life. Results show that service provision had institutional qualities; participants experienced lack of information and reduced possibilities for social inclusion and community participation like everyone else. More attention on the role of policy development, support staff and leadership, in relation to facilitating an everyday life with more user involvement, social inclusion and community participation of people needing support, is essential. Participatory, appreciative, action and reflection in workshops for persons with intellectual disabilities and support staff represent a promising approach to promote the voices and interests of persons with intellectual disabilities. Accessible abstract This article tells you about the everyday life of people with intellectual disabilities living in Norway. Nine people with intellectual disabilities worked together with two university researchers and two intellectual disability nurses in the community, in workshops. The people with intellectual disabilities liked to have their own apartment and going to work every day. They said that they wanted more social participation with friends and more participation in activities in the community, just like everyone else. They wanted to be treated with more respect by their staff. All participants in the project saw great value in working together and some of them are working together in a new project about involvement in the improvement of support services for people with intellectual disabilities.

Premorbid intellectual functioning and risk of schizophrenia and spectrum disorders.

2006-02-01

Evidence from longitudinal studies indicates that lower IQ score in childhood and early adolescence increases risk of schizophrenia and schizophrenia spectrum disorders (SSD). This study investigated the association between premorbid IQ and risk of SSD in a population-based cohort of 17-year-old conscripts. Fifty four thousand males assessed by the Israeli Draft Board during two consecutive years were followed by means of the Israeli National Psychiatric Hospitalization Case Registry for up to 11 years. Tests of verbal and non-verbal reasoning, mathematical knowledge and instructions comprehension and several psychosocial variables were recorded by the Draft Board. Risk for SSD increased with decreasing IQ score. Only poorer non-verbal reasoning conferred a significant increased risk for SSD after taking into account general intellectual ability. IQ was not associated with age of onset. These results confirm the importance of low intellectual functioning as a risk factor for SSD. This is unlikely to be due to prodrome.

Physical inactivity and high rates of chronic conditions is a public health concern for adults with intellectual disability. Few health promotion programs target the group home setting which is the pre-dominant form of residential accommodation for persons with intellectual disability. A process evaluation of a physical activity health promotion program, Menu-Choice, was conducted with five group home sites for adults with intellectual and developmental disabilities. Menu-Choice assists group home staff in including physical activity goals within resident schedules. The physical activity program was designed based on theoretical frameworks, community-based participatory approaches, and established health promotion guidelines for adults with disabilities. Fourteen program coordinators (age M 39; 77% females), 22 staff (age M 39; 82% females), and 18 residents (age M 59; 72% females; 56% ambulatory) participated. Results from the fidelity survey and program completion highlight potential challenges with implementation. Findings will assist with the refinement of the program for continued implementation trials in the group home community. Published by Elsevier Ltd.

This article provides a systematic analysis of how health promotion is being conceptualised for people with intellectual disabilities and how health promotion can work best in the light of this group's specific needs and limitations. Rodgers' evolutionary concept analysis. MEDLINE, PsycINFO, CINAHL and SocINDEX were searched using the search terms 'health promotion', 'people with intellectual disabilities' and 'developmental disabilities'. This review includes studies published between 1992 and 2014. A total of 52 articles were included. Health promotion for people intellectual disabilities, as discussed in the literature, focuses on four aspects, namely supporting a healthy lifestyle, providing health education, involving supporters and being person-centred. Antecedents of the concept 'health promotion for people with intellectual disabilities' were healthcare access and sensitised healthcare providers. The outcomes were improved health, being empowered, enhanced quality of life and reduced health disparities. This analysis provides a solid foundation for healthcare stakeholders' planning, implementing and evaluating health-promotion activities for people with intellectual disabilities at the policy level and in the community. © 2017 Nordic College of Caring Science.

Mid-hindbrain malformations can occur during embryogenesis through a disturbance of transient and localized gene expression patterns within these distinct brain structures. Rho guanine nucleotide exchange factor (ARHGEF) family members are key for controlling the spatiotemporal activation of Rho GTPase, to modulate cytoskeleton dynamics, cell division, and cell migration. We identified, by means of whole exome sequencing, a homozygous frameshift mutation in the ARHGEF2 as a cause of intellectual disability, a midbrain-hindbrain malformation, and mild microcephaly in a consanguineous pedigree of Kurdish-Turkish descent. We show that loss of ARHGEF2 perturbs progenitor cell differentiation and that this is associated with a shift of mitotic spindle plane orientation, putatively favoring more symmetric divisions. The ARHGEF2 mutation leads to reduction in the activation of the RhoA/ROCK/MLC pathway crucial for cell migration. We demonstrate that the human brain malformation is recapitulated in Arhgef2 mutant mice and identify an aberrant migration of distinct components of the precerebellar system as a pathomechanism underlying the midbrain-hindbrain phenotype. Our results highlight the crucial function of ARHGEF2 in human brain development and identify a mutation in ARHGEF2 as novel cause of a neurodevelopmental disorder.

Intellectual disability is a common neurodevelopmental disorder characterized by impaired intellectual and adaptive functioning. Both environmental insults and genetic defects contribute to the etiology of intellectual disability. Copy number variations of SORBS2 have been linked to intellectual disability. However, the neurobiological function of SORBS2 in the brain is unknown. The SORBS2 gene encodes ArgBP2 (Arg/c-Abl kinase binding protein 2) protein in non-neuronal tissues and is alternatively spliced in the brain to encode nArgBP2 protein. We found nArgBP2 colocalized with F-actin at dendritic spines and growth cones in cultured hippocampal neurons. In the mouse brain, nArgBP2 was highly expressed in the cortex, amygdala, and hippocampus, and enriched in the outer one-third of the molecular layer in dentate gyrus. Genetic deletion of Sorbs2 in mice led to reduced dendritic complexity and decreased frequency of AMPAR-miniature spontaneous EPSCs in dentate gyrus granule cells. Behavioral characterization revealed that Sorbs2 deletion led to a reduced acoustic startle response, and defective long-term object recognition memory and contextual fear memory. Together, our findings demonstrate, for the first time, an important role for nArgBP2 in neuronal dendritic development and excitatory synaptic transmission, which may thus inform exploration of neurobiological basis of SORBS2 deficiency in intellectual disability. Copy number variations of the SORBS2 gene are linked to intellectual disability, but the neurobiological mechanisms are unknown. We found that nArgBP2, the only neuronal isoform encoded by SORBS2, colocalizes with F-actin at neuronal dendritic growth cones and spines. nArgBP2 is highly expressed in the cortex, amygdala, and dentate gyrus in the mouse brain. Genetic deletion of Sorbs2 in mice leads to impaired dendritic complexity and reduced excitatory synaptic transmission in dentate gyrus granule cells, accompanied by behavioral deficits in acoustic startle response and long-term memory. This is the first study of Sorbs2 function in the brain, and our findings may facilitate the study of neurobiological mechanisms underlying SORBS2 deficiency in the development of intellectual disability.

The aim of this study was to evaluate the effect of prenatal and postnatal malnutrition on the intellectual functioning of early school-aged children. We followed the offspring of women who had participated in a trial of prenatal supplementation with different combinations of micronutrients and who remained resident in the study field. We measured their intellectual functioning using the Wechsler intelligence scale for children (WISC-IV). Height-for-age, weight-for-age, and body mass index (BMI)-for-age were used as anthropometric nutritional status indices. Four of the 5 composite scores derived from the WISC-IV, except for working memory index (WMI), were significantly lower in low birth weight children after adjusting for confounds. All 5 composite scores, including full-scale intelligence quotient (FSIQ), verbal comprehension index (VCI), WMI, perceptual reasoning index (PRI), and processing speed index (PSI) were significant lower in stunted and underweight children. The differences in the means of WISC-IV test scores were greatest between stunted and nonstunted children. The means for FSIQ, VCI, WMI, PRI, and PSI were as follows: 5.88 (95% confidence interval [CI]: 2.84-8.92), 5.08 (95% CI: 1.12-8.41), 4.71 (95% CI: 1.78-7.66), 6.13 (95% CI: 2.83-9.44), and 5.81 (95% CI: 2.61-9.00). These means were lower in stunted children after adjusting for confounds. Our results suggest the important influences of low birth weight and postnatal malnutrition (stunting, low body weight) on intellectual functioning in early school-aged children.

Although obesity has been related to measures of academic achievement and cognition in children, the influence of fat distribution, specifically visceral adiposity, on select aspects of achievement and cognitive function remains poorly characterized among preadolescent children. The aim of this study was to evaluate the relation of adiposity, particularly visceral adipose tissue, on achievement and cognitive function among children. Children with obesity (ages 7-9 years old, N= 55, 35 females) completed cognitive and academic tests. Normal weight children (N= 55, 35 females) were matched to this group on demographic characteristics and aerobic fitness. Covariate analyses included age, Brief Intellectual Ability (BIA), SES, and fat free VO2 (VO2 peak adjusted for lean mass; ml/kg lean/min). Adiposity (i.e., whole body percent fat, subcutaneous abdominal adipose tissue (SAAT), and visceral adipose tissue (VAT)) was assessed using dual energy X-ray absorptiometry. The results of this study revealed that, relative to their normal weight counterparts, children with obesity had significantly lower performance on tests of reading and math. Analyses revealed that among children with obesity, %Fat and SAAT were not related to cognitive abilities. However, higher VAT was associated with poorer intellectual abilities, p's≤0.04; and cognitive performance (i.e. Thinking Ability and Cognitive Efficiency), p's≤0.04. However, among normal weight children, VAT was positively associated with intellectual abilities and cognitive efficiency. In conclusion, the results suggest that VAT was selectively and negatively related with cognition among children with obesity. Along with the dangerous metabolic nature of VAT, its detrimental relationship with obese children's intellectual and cognitive functioning is concerning.

Participation in leisure activities is a fundamental human right and an important factor of quality of life. Adults with intellectual disabilities (ID) and physical disabilities often experience limited opportunities to participate in leisure activities, virtual reality (VR) technologies may serve to broaden their repertoire of accessible leisure activities. Although the use of VR in rehabilitation has grown over the past decade, few applications have been reported for people with ID. Thirty-three men and women with moderate ID and severe cerebral palsy participated in the study. Each participant in the experimental group (n=17) took part in VR activity two to three times weekly for 12 weeks. Virtual games were provided via GestureTek's Gesture Xtreme video capture VR system. The VR-based activities were perceived by the participants to be enjoyable and successful. Moreover, participants demonstrated clear preferences, initiation and learning. They performed consistently and maintained a high level of interest throughout the intervention period. VR appears to provide varied and motivating opportunities for leisure activities among young adults with intellectual and physical disabilities. Its ease of use and adaptability make it a feasible option for this population.

QEEG characteristics and spectrum weighted frequency for children diagnosed as autistic spectrum disorder

PubMed Central

2010-01-01

Background Autistic spectrum disorders are a group of neurological and developmental disorders associated with social, communication, sensory, behavioral and cognitive impairments, as well as restricted, repetitive patterns of behavior, activities, or interests. The aim of this study was a) to analyze QEEG findings of autistic patients and to compare the results with data base; and b) to introduce the calculation of spectrum weighted frequency (brain rate) as an indicator of general mental arousal in these patients. Results Results for Q-EEG shows generally increased delta-theta activity in frontal region of the brain. Changes in QEEG pattern appeared to be in a non-linear correlation with maturational processes. Brain rate measured in CZ shows slow brain activity (5. 86) which is significantly lower than normal and corresponds to low general mental arousal. Recent research has shown that autistic disorders have as their basis disturbances of neural connectivity. Neurofeedback seems capable of remediating such disturbances when these data are considered as part of treatment planning. Conclusions Prognosis of this pervasive disorder depends on the intellectual abilities: the better intellectual functioning, the possibilities for life adaptation are higher QEEG shows generally increased delta-theta activity in frontal region of the brain which is related to poor cognitive abilities. Brain rate measured in CZ shows slow brain activity related to under arousal. Pharmacotherapy combined with behavior therapy, social support and especially neurofeedback technique promise slight improvements PMID:20920283

Longitudinal trajectories of intellectual and adaptive functioning in adolescents and adults with Williams syndrome.

PubMed

Fisher, M H; Lense, M D; Dykens, E M

2016-10-01

Williams syndrome (WS) is associated with a distinct cognitive-behavioural phenotype including mild to moderate intellectual disability, visual-spatial deficits, hypersociability, inattention and anxiety. Researchers typically characterise samples of individuals with WS by their intellectual functioning and adaptive behaviour. Because of the low prevalence of the syndrome, researchers often include participants with WS across a broad age range throughout childhood and adulthood and assume participants demonstrate consistent cognitive development across ages. Indeed, IQ scores are generally stable for children and adolescents with WS, although there are significant individual differences. It is less clear whether this pattern of stable intellectual ability persists into adulthood. Furthermore, while adaptive behaviour is an important indicator of an individual's ability to apply their conceptual skills to everyday functioning, conflicting findings on the trajectories of adaptive behaviour in adolescents and adults with WS have been reported. The current study examined longitudinal profiles of cognitive and adaptive functioning in adolescents and adults with WS. To examine cognitive functioning, participants included 52 individuals with WS (51.9% men) who were assessed with the Kaufman Brief Intelligence Test, 2nd edition (KBIT-2) between two and seven times. At their first assessment, participants had a mean age of 25.4 years (SD = 8.4), ranging in age from 14.2 to 48.9 years. To assess adaptive behaviour, participants included a subset of 28 individuals with WS whose parents completed the Vineland Adaptive Behavior Scale, 2nd edition (VABS-II) between two and five times. At their initial administration, participants ranged from 17.1-40.2 years of age, with a mean age of 26.5 years (SD = 7.3). A series of multilevel models were used to examine changes in KBIT-2 Composite IQ, Verbal IQ and Nonverbal IQ standard scores over time, as well as the Adaptive Behavior Composite, and the Communication, Daily Living Skills and Socialization subdomains of the VABS-II. Consistent with the WS cognitive profile, IQ scores were significantly lower than the general population IQ score of 100, and there was significant variability in individual IQ scores and slopes. KBIT-2 IQ scores were generally stable across adolescents and adults with WS. Adaptive behaviour scores were significantly lower than the population mean score of 100, and there was significant variability in individuals' adaptive behaviour scores but not trajectories. However, in contrast to the findings with the KBIT-2, VABS-II scores were observed to significantly decrease over time. Findings suggest that while intellectual functioning remains stable, adaptive functioning does not remain stable across adolescence and adulthood in individuals with WS. Implications for the relation between cognitive and adaptive functioning across development are discussed, with a focus on how this relates to specific aspects of the WS phenotype. © 2016 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

Introduction Individuals with intellectual disabilities are rarely targeted by the current human immunodeficiency virus (HIV) response, thereby reducing their access to HIV information and services. Currently, little is known about the HIV knowledge and sexual practices of young Nigerians with intellectual disabilities. Thus, this study sought to compare the HIV knowledge and sexual practices of learners with mild/moderate intellectual disabilities and non-disabled learners (NDL) in Nigeria. Findings could help in the development of HIV interventions that are accessible to Nigerian learners with intellectual impairments. Methods This cross-sectional, comparative study utilized a survey to investigate HIV knowledge and sexual practices among learners with mild/moderate intellectual disabilities and NDL in Nigeria. Learners with mild/moderate intellectual disabilities (n=300) and NDL (n=300) within the age range of 12 to 19 years drawn from schools across Oyo State, Nigeria, completed a structured questionnaire to assess their knowledge of HIV transmission and sexual practices. Results Significantly more learners with mild/moderate intellectual disabilities (62.2%) than NDL 48 (37.8%) reported having sexual experience (p=0.002). Of the sexually experienced female learners with mild/moderate intellectual disabilities, 28 (68.3%) reported history of rape compared with 9 (2.9%) of female NDL (p=0.053). Intellectual impairment was significantly associated with lower HIV transmission knowledge scores (p<0.001). Learners with mild/moderate intellectual disabilities were less likely than NDL (p<0.001) to have heard about HIV from most of the common sources of HIV information. In addition, when compared with non-disabled learners, learners with mild/moderate intellectual disabilities were significantly more likely to have reported inconsistent condom use with boyfriends/girlfriends (p<0.001), with casual sexual partners (p<0.001) and non-use of condom during last sexual activity (p<0.001). Conclusions Findings suggest that adolescents with intellectual impairments are at higher risk of HIV infection than their non-disabled peers. This gap could be addressed through interventions that target Nigerians with intellectual impairments with accessible HIV information and services. PMID:23394898

BACKGROUND Our goal was to specify the relationship between the level of activity (intellectual, physical, and social) in persons diagnosed with mild cognitive impairment (MCI) and the further progression of cognitive dysfunction. MATERIAL AND METHODS We examined 193 patients diagnosed with MCI (according to the criteria of the Working Group on Mild Cognitive Impairment) and under treatment at our Mental Disorders Clinic. It was assumed that these persons would remain under systematic psychiatric observation until dementia was diagnosed. The present study results from a seven-year observation period. The mini-mental state examination (MMSE), the Activity Scale (with the intellectual, physical, and social subscales), and the Instrumental Activities of Daily Living (IADL) scale were used to evaluate the participants' status at baseline. The MMSE was re-administered after one year and again at the end of the observation (either upon diagnosis of dementia or after seven years). At each meeting with the participant, the clinical diagnosis was verified to determine if the patient had dementia or not. Of the 193 people initially qualified for the study, 75 were available for the final analysis. RESULTS It was found that there was no statistically significant difference in the baseline MMSE scores between the persons with stable MCI and the persons who had progressed to dementia. However, statistically significant differences in the level of activity at baseline on both the global IADL scale and the Activity Scale between those with stable MCI and those who had progressed to dementia were found. These differences were manifested in the IADL subscales for telephone use, shopping, transportation, and personal finances, and in the physical activity subscale. CONCLUSIONS An evaluation of intellectual, physical, and social activity can be useful in determining the prognosis for the future course of MCI.

Lifelong Brain Health is a Lifelong Challenge: From Evolutionary Principles to Empirical Evidence

Although the human brain is exceptional in size and information processing capabilities, it is similar to other mammals with regards to the factors that promote its optimal performance. Three such factors are the challenges of physical exercise, food deprivation/fasting, and social/intellectual engagement. Because it evolved, in part, for success in seeking and acquiring food, the brain functions best when the individual is hungry and physically active, as typified by the hungry lion stalking and chasing its prey. Indeed, studies of animal models and human subjects demonstrate robust beneficial effects of regular exercise and intermittent energy restriction/fasting on cognitive function and mood, particularly in the contexts of aging and associated neurodegenerative disorders. Unfortunately, the agricultural revolution and the invention of effort-sparing technologies have resulted in a dramatic reduction or elimination of vigorous exercise and fasting, leaving only intellectual challenges to bolster brain function. In addition to disengaging beneficial adaptive responses in the brain, sedentary overindulgent lifestyles promote obesity, diabetes and cardiovascular disease, all of which may increase the risk of cognitive impairment and Alzheimer’s disease. It is therefore important to embrace the reality of the requirements for exercise, intermittent fasting and critical thinking for optimal brain health throughout life, and to recognize the dire consequences for our aging population of failing to implement such brain-healthy lifestyles.

CNNM2 Mutations Cause Impaired Brain Development and Seizures in Patients with Hypomagnesemia

Intellectual disability and seizures are frequently associated with hypomagnesemia and have an important genetic component. However, to find the genetic origin of intellectual disability and seizures often remains challenging because of considerable genetic heterogeneity and clinical variability. In this study, we have identified new mutations in CNNM2 in five families suffering from mental retardation, seizures, and hypomagnesemia. For the first time, a recessive mode of inheritance of CNNM2 mutations was observed. Importantly, patients with recessive CNNM2 mutations suffer from brain malformations and severe intellectual disability. Additionally, three patients with moderate mental disability were shown to carry de novo heterozygous missense mutations in the CNNM2 gene. To elucidate the physiological role of CNNM2 and explain the pathomechanisms of disease, we studied CNNM2 function combining in vitro activity assays and the zebrafish knockdown model system. Using stable Mg2+ isotopes, we demonstrated that CNNM2 increases cellular Mg2+ uptake in HEK293 cells and that this process occurs through regulation of the Mg2+-permeable cation channel TRPM7. In contrast, cells expressing mutated CNNM2 proteins did not show increased Mg2+ uptake. Knockdown of cnnm2 isoforms in zebrafish resulted in disturbed brain development including neurodevelopmental impairments such as increased embryonic spontaneous contractions and weak touch-evoked escape behaviour, and reduced body Mg content, indicative of impaired renal Mg2+ absorption. These phenotypes were rescued by injection of mammalian wild-type Cnnm2 cRNA, whereas mammalian mutant Cnnm2 cRNA did not improve the zebrafish knockdown phenotypes. We therefore concluded that CNNM2 is fundamental for brain development, neurological functioning and Mg2+ homeostasis. By establishing the loss-of-function zebrafish model for CNNM2 genetic disease, we provide a unique system for testing therapeutic drugs targeting CNNM2 and for monitoring their effects on the brain and kidney phenotype.

Facilitating the use of public transportation enhances opportunities for independent living and competitive, community-based employment for individuals with intellectual and developmental disabilities (IDD). Four young adults with IDD were taught through total-task chaining to use the Google Maps application, a self-prompting, visual navigation system, to take the bus to locations around a college campus and the community. Three of four participants learned to use Google Maps to independently navigate public transportation. Google Maps may be helpful in supporting independent travel, highlighting the importance of future research in teaching navigation skills. Learning to independently use public transportation increases access to autonomous activities, such as opportunities to work and to attend postsecondary education programs on large college campuses.Individuals with IDD can be taught through chaining procedures to use the Google Maps application to navigate public transportation.Mobile map applications are an effective and functional modern tool that can be used to teach community navigation.

[Hygiene requirements for the level of intellectual intensivity loads in foreign language learning].

2013-01-01

The material of this article provides information about the basics of hygiene conditions and nature of intellectual loads of students of secondary schools in the perception of information in a foreign language. Are the most favorable conditions for the successful training of perception and assimilation of information supplied in the course of the learning process in one foreign language or some more different ones? It was found that the process of perception and assimilation of educational information in foreign languages is associated with some degree of mental and emotional stress of students. At the same time, the effectiveness of the learning process depends on the degree of stress. Certain parameters of the psychological and emotional stress students usually have a stimulating effect on their central nervous system. Another level, the psychological and emotional stress of students on the contrary, causes a braking effect of functional activity of the relevant structures of the central nervous system of students and reduces the effectiveness of training.

population ageing will lead to a leap in the dementia population in Asia. However, information about potentials for low-cost and low-risk interventions is limited. to study the associations between lifestyle activities and global cognition from the Cognitive and Lifestyle Activity Study for Seniors in Asia (CLASSA). a cross-sectional study. we studied the association between global cognition and lifestyle activity participation in community living older adults (60 years or over) across nine sites in East Asia. A standardised lifestyle activity questionnaire exploring activities from four categories (intellectual, physical, social and recreational) was used to measure the pattern. Global cognition was categorised by locally validated versions of Mini-mental state examination (MMSE) or Montreal Cognitive Assessment (MoCA) (good cognition, GC-scored at the top 25% among participants with no significant cognitive deficit (SCD); normal cognition, NC-middle 50% among participants with no SCD; mild cognitive deficit, MCD-lowest 25% among participants with no SCD; SCD-below local cut-offs for dementia). two thousand four hundred and four (1,009 men; 1,395 women) participants were recruited. The mean age was 71.0 (7.2) years. A higher variety of intellectual and physical activities were associated with GC; more social activities were associated with higher risks of having impaired cognition (multinomial logistic regression). The same association was found in participants with no SCD and had regular activities for over 10 years (n = 574). intellectual activity and physical exercise were associated with better cognitive states in Asian older adults. Community-based intervention may take considerations into specific types of activities to optimise cognition. © The Author 2015.

Background/Aims Little is known about the relationship between cognitive functions and higher-level functional capacity (e.g. intellectual activity, social role, and social participation) in Parkinson's disease (PD). The purpose of this study was to clarify neuropsychological characteristics and their association with higher-level functional capacity in PD patients. Methods Participants were 31 PD patients and 23 demographically matched healthy controls. Neuropsychological tests were conducted. One year later, a questionnaire survey evaluated higher-level functional capacity in daily living. Results The PD group scored significantly lower than the control group in all cognitive domains, particularly executive function and processing. Executive function, processing speed, language, and memory were significantly correlated with higher-level functional capacity in PD patients. Stepwise regression showed that only executive function (Trail Making Test-B), together with disease severity (HY stage), predicted the higher-level functional capacity. Conclusion Our findings provide evidence of a relationship between executive function and higher-level functional capacity in patients with PD. PMID:26273243

Hall v. Florida: defining intellectual disability in the shadow of the death penalty.

PubMed

Appelbaum, Paul S

2014-10-01

When the U.S. Supreme Court held that persons with mental retardation (now called intellectual disability) could not be sentenced to death, it left the question of how to define the condition to the states. That issue was raised in Hall v. Florida, which challenged one state's "bright-line rule" barring consideration of defendants with IQs over 70. In an endorsement of the professional consensus, the justices ruled that a more flexible approach that takes into account both intellectual and adaptive functioning is required. The Court's posture may bode well for its acceptance of mental health expertise in future cases.

Space Shuttle, private enterprise and intellectual properties in the context of space manufacturing

It is a national policy to make the capabilities of the Space Transportat ion System available to a wide range of potential users. This includes its availability as a space manufacturing facility for commercial activities, which may be carried out on a reimbursable basis or as a joint endeavor with NASA, but with substantial private investment. In any high risk, long lead-time research and development activity directed towards commercialization, the protection afforded the results of the research and development under the laws relating to intellectual property rights may provide an important incentive for private investment. The paper reviews NASA's policies and practices for the protection of privately-established intellectual property rights involved in STS use, with particular emphasis on reimbursable launch agreements and joint endeavor agreements.

Previous experiences with people with both physical and intellectual functional diversity around palaeontological issues have demonstrated the important value of science outreach directed to people with disabilities. The aforementioned practices act twofold: as a learning tool and also improving the quality of life of the participants and thus, their self-image. All these pioneer experiences were the first step in a process of developing new attitudes contributing the 2030 Agenda for Sustainable Development of United Nations, where among the 17 goals proposed an effective social inclusion of people with disabilities is required. For this, real inclusive practices in geological outreach are imperious. A close cooperation with all the parts (researchers and participants), in a kind of coworking attitude is needed. This Inclusive-Coworking is considered in the sense of social gathering in order to share equal values and look for the synergy that this different outlook implies. And what is more important: the change of role of the previously learners into an active part of the scientific outreach, providing the adequate methodology for that. The offer of non-formal learning activities normally includes the participation of university professors and researchers in Science Week editions. During the 2016 session in Madrid, four adults with intellectual disability who were participants in the previous edition, contributed in the palaeontological workshop. They were in charge of four of the eight modules explaining the origin of fossils and how to collect them, the evolution of equids' limbs, and the main dentition types in vertebrates to the twenty 16 year old secondary students who attended the workshop. During the development of the experience all the students were pleased with the inclusive approach, and the interaction of all participants was fruitful. Although the explanations took a bit more time when made by our functional diverse fellows, all the abstracts concepts were correctly described and the social perspective of the experience had an excellent reception. This activity was prepared and designed with expert educators and other professionals related to disability in order to guide the scientists with regard to the learning strategies and specific needs of the attendees. Most of our previous activities dealing with palaeontology were targeted either towards people with, or without disabilities, but never mixing them. So far, successful lab-based activities adapted to people with both intellectual and sensory disabilities have been developed, but this is the first experience in which functional diversity people act as teachers themselves. This is an important step forward in eliminate barriers to non-formal education. We hope that our actions, based on the Agenda for Sustainable Development more Inclusive model, can inspire other actions and programs dealing Accessible Geoscience. This work was funded by the project INNOVA-DOCENCIA 2 (2016-17) "Geodivulgar: Geología y Sociedad" of the Universidad Complutense de Madrid. We want to thank the non-profit association Ciencia sin Barreras for their valuable help during the development of Geodivulgar activities, as well as all the students volunteers.

Nearly half of children with intellectual disability (ID) have comorbid affective disorders. These problems are chronic if left untreated and can significantly impact upon future vocational, educational, and social opportunities. Despite this, there is a paucity of research into effective treatments for this population. Notably, one of the most supported of psychological therapies, cognitive behaviour therapy (CBT), remains largely uninvestigated in children with ID. The current review considers the neuropsychological profile of children and adolescents with mild to moderate ID, with a view to informing how CBT might best be adapted for children and adolescents with ID. Narrative review of literature considering the neuropsychological profiles of children and adolescents with ID, with specific focus upon attention, memory, learning, executive functioning, and communication. Studies were identified through SCOPUS, PsycINFO, and PubMed databases, using combinations of the key words 'intellectual disability', 'learning disability', 'neuropsychology', 'attention', 'learning', 'memory', 'executive function', 'language', and 'reading'. Children with ID have significant deficits in attention, learning, memory, executive functions, and language. These deficits are likely to have a negative impact upon engagement in CBT. Suggestions for adapting therapy to accommodate these wide ranging deficits are proposed. There are multiple cognitive factors which need to be considered when modifying CBT for children who have ID. Furthermore, research is required to test whether CBT so modified is effective in this population. Clinical implications Effective ways of providing cognitive behavioural therapy (CBT) to children with intellectual disability (ID) is unclear. This study provides a framework of potential adaptations for clinical practice As rates of mental illness for children with intellectual disability are high, and rates of treatment provision low, it is hoped that the recommendations provided in this study will encourage more mental health practitioners to provide CBT to children with ID. Limitations These recommendations are based only upon neuropsychological literature. Trialling the effectiveness of an adapted form of CBT for children and adolescents with ID is required. There are varying causes of intellectual disability, with differences in cognitive profiles. The utility of the recommendations made here may vary according to specific aetiologies. © 2017 The British Psychological Society.
