DeFelice, Magee L; Ruchelli, Eduardo D; Markowitz, Jonathan E; Strogatz, Melissa; Reddy, Krishna P; Kadivar, Khadijeh; Mulberg, Andrew E; Brown, Kurt A

2003-08-01

A relationship between autism and gastrointestinal (GI) immune dysregulation has been postulated based on incidence of GI complaints as well as macroscopically observed lymphonodular hyperplasia and microscopically determined enterocolitis in pediatric patients with autism. To evaluate GI immunity, we quantitatively assessed levels of proinflammatory cytokines, interleukin (IL)-6, IL-8, and IL-1beta, produced by intestinal biopsies of children with pervasive developmental disorders. Fifteen patients, six with pervasive developmental disorders and nine age-matched controls, presenting for diagnostic colonoscopy were enrolled. Endoscopic biopsies were organ cultured, supernatants were harvested, and IL-6, IL-8, and IL-1beta levels were quantified by ELISA. Tissue histology was evaluated by blinded pathologists. Concentrations of IL-6 from intestinal organ culture supernatants of patients with pervasive developmental disorders (median 318.5 pg/ml, interquartile range 282.0-393.0 pg/ml) when compared with controls (median 436.9 pg/ml, interquartile range 312.6-602.5 pg/ml) were not significantly different (p = 0.0987). Concentrations of IL-8 (median 84,000 pg/ml, interquartile range 16,000-143,000 pg/ml) when compared with controls (median 177,000 pg/ml, interquartile range 114,000-244,000 pg/ml) were not significantly different (p = 0.0707). Concentrations of IL-1beta (median 0.0 pg/ml, interquartile range 0.0-94.7 pg/ml) when compared with controls (median 0.0 pg/ml, interquartile range 0.0-60.2 pg/ml) were not significantly different (p = 0.8826). Tissue histology was nonpathological for all patients. We have demonstrated no significant difference in production of IL-6, IL-8, and IL-1beta between patients with pervasive developmental disorders and age-matched controls. In general, intestinal levels of IL-6 and IL-8 were lower in patients with pervasive developmental disorders than in age-matched controls. These data fail to support an association between autism and GI inflammation.

Autism and Related Disorders

2012-01-01

The Pervasive Developmental Disorders are a group of neurodevelopmental disorders that include Autistic Disorder, Asperger’s Disorder, Pervasive Developmental Disorder - Not Otherwise Specified (PDD-NOS), Childhood Disintegrative Disorder (CDD), and Rett’s Disorder. All feature childhood onset with a constellation of symptoms spanning social interaction and communication and including atypical behavior patterns. The first three disorders (Autistic Disorder, Asperger’s Disorder, and PDD-NOS) are currently referred to as Autism Spectrum Disorders, reflecting divergent phenotypic and etiologic characteristics compared to Rett’s Disorder and CDD. This chapter reviews relevant research and clinical information relevant to appropriate medical diagnosis and treatment. PMID:22608634

Children with a pervasive developmental disorder show in addition to core symptoms a variety of genetic syndromes as well as neurological problems, which are relevant for the treatment and the course of the disorder. The objective of our study is to analyse the nature and the frequency of these co-morbid somatic disorders in relation to the level of intellectual functioning of the patients. The sample consists of 601 patients with a pervasive developmental disorder diagnosed at the Department of Developmental Disorders at the Heckscher-Klinikum between 1997 and 2007. In addition to genetic syndromes, we also recorded a variety of neurological disorders. 373 of the patients (62%) had at least one additional diagnosis and 121 (20%) had at least two additional diagnoses on Axis IV of the multi-axial classification scheme. Genetic syndromes were found in 6% of the patients (N = 37). Movement disorders (N = 214; 35.6%) and epilepsy (N = 98; 16.3%) were the most frequent neurological disorders. Children with mental retardation showed significantly more somatic diagnoses than children without mental retardation. Children with pervasive developmental disorders show a wide variety of co-morbid somatic problems, which are relevant for the treatment and the course of the disorder. Children with autism and mental retardation show more co-morbid conditions and are more impaired in their psychosocial adaptation than children with autism without mental retardation.

2002-05-01

Pediatric populations, including those with autistic disorder or other pervasive developmental disorders, increasingly are being prescribed selective serotonin reuptake inhibitors (SSRIs). Little is known about the age-related brain pharmacokinetics of SSRIs; there is a lack of data regarding optimal dosing of medications for children. The authors used fluorine magnetic resonance spectroscopy ((19)F MRS) to evaluate age effects on whole-brain concentrations of fluvoxamine and fluoxetine in children taking SSRIs. Twenty-one pediatric subjects with diagnoses of autistic disorder or other pervasive developmental disorders, 6-15 years old and stabilized with a consistent dose of fluvoxamine or fluoxetine, were recruited for the study; 16 successfully completed the imaging protocol. Whole-brain drug levels in this group were compared to similarly acquired data from 28 adults. A significant relationship between dose and brain drug concentration was observed for both drugs across the age range studied. Brain fluvoxamine concentration in the children was lower, consistent with a lower dose/body mass drug prescription; when brain concentration was adjusted for dose/mass, age effects were no longer significant. Brain fluoxetine concentration was similar between age groups; no significant age effects on brain fluoxetine drug levels remained after adjustment for dose/mass. Observations of brain fluoxetine bioavailability and elimination half-life also were similar between age groups. These findings suggest that fluvoxamine or fluoxetine prescriptions adjusted for dose/mass are an acceptable treatment approach for medicating children with autistic disorder or other pervasive developmental disorders. It must be determined whether these findings can be generalized to other pediatric populations.

2011-09-01

We reviewed the stability of the diagnosis of pervasive developmental disorder not otherwise specified (PDD-NOS). A Medline search found eight studies reiterating a diagnostic assessment for PDD-NOS. The pooled group included 322 autistic disorder (AD) and 122 PDD-NOS cases. We used percentage of individuals with same diagnose at Times 1 and 2 as response criterion. The pooled Relative Risk was 1.95 (p < 0.001) showing that AD diagnostic stability was higher than PDD-NOS. When diagnosed before 36 months PDD-NOS bore a 3-year stability rate of 35%. Examining the developmental trajectories showed that PDD-NOS corresponded to a group of heterogeneous pathological conditions including prodromic forms of later AD, remitted or less severe forms of AD, and developmental delays in interaction and communication.

Understanding the autistic dental patient.

PubMed

Green, Danielle; Flanagan, Dennis

2008-01-01

Autism spectrum disorder (ASD) is one of many pervasive developmental disorders (PDD); others include Rett syndrome, childhood disintegrative disorder (also known as Heller's syndrome), pervasive developmental disorder not otherwise specified (PDD-NOS), and the higher functioning Asperger's syndrome. Because ASD is the most common of the developmental disabilities, it is not unusual for dentists to have ASD patients among their patient population. As the name indicates, ASD varies widely in its clinical manifestations; however, dentists are likely to encounter difficulties with communication and socialization. Although communication may be difficult, it is not impossible. A thorough understanding of this complex neurological disorder and displaying patience are vital for the dentist. This article seeks to familiarize readers with ASD characteristics and co-morbid conditions that may affect dental treatment and provide some management strategies for this unique population.

Left temporal arachnoid cyst and specific learning disorders associated with pervasive developmental disorders - not otherwise specified (PDD-NOS): contributions of an integrative neuro-psychomotor, neuropsychological, psychopathological and neurosurgical approach about a case report in a child (François). With DSM-IV and DSM-IV-TR, the terminology of pervasive developmental disorders (PDD) covers two main categories of infantile disorders: disorders of "strictly" autistic nature and pervasive developmental disorders - not otherwise specified (PDD-NOS). Under the terminology of multiple complex developmental disorder (MCDD), it is proposed to classify children presenting symptoms approaching the psychotic disharmonies and usually diagnosed as PDD-NOS. Such a category of developmental disorders is now included without nosographic distinction in the autistic spectrum in the Diagnostic and Statistical Manual of mental disorders (DSM-V). We are reporting a case report of a 6-year-old boy which shows a PDD-NoS/MCDD complex symptomatology type. This child presents multiple disorders: minor neurological signs (soft signs), neuro-psychomotor disorders, developmental coordination disorder (DCD), communication, thought, and regulation of emotions disorders, attention deficit disorders (ADD); in the presence of a high verbal intellectual potential, which makes it difficult to establish a clear diagnosis. A cerebral magnetic resonance imaging (MRI) was carried out due to the presence of minor neurological signs (soft signs) and of neurodevelopmental multiple disorders. The MRI revealed a voluminous arachnoid temporo-polar left cyst with a marked mass effect on the left temporal lobe. A neurosurgical intervention allowed to observe the gradual disappearance of the specific symptomatology (in particular soft signs, neuro-psychomotor functions and autistic symptoms) secondary to the interference of the cyst's pressure with intracranial areas involving neurological and psychopathological abnormalities, underlying at the same time the reversibility of the disorders after decompression as demonstrated in some studies. There are always, with a quantitative and qualitative decrease, an emotional dysregulation, a DCD, an ADD as well as impairments in the executive functions. This clinical case underlines the necessity of an evaluation in a transdisciplinary way and to follow the developmental evolution of the child in order to focus adapted therapeutics. Furthermore, with neurodevelopmental disorders not specified, it is important to examine the presence of soft signs with standardized neuro-psychomotor assessment, and then, to propose an MRI investigation. To our knowledge, this is the first report in the literature with a school age child of an unusual association between a temporal arachnoid cyst associated with PDD-NOS/MCDD.

We followed 74 children with autistic disorder (AD) and 39 children with pervasive developmental disorder not otherwise specified (PDD NOS) for 17-38 years in a record linkage study. Rates of disability pension award, marital status, criminality and mortality were compared between groups. Disability pension award was the only outcome measure that differed significantly between the AD and PDD NOS groups (89% vs. 72%, p < 0.05). The lower rate of disability pension award in the PDD NOS group was predicted by better psychosocial functioning. The lack of substantial differences in prognosis between the groups supports a dimensional description of autism spectrum disorder, in line with proposed DSM-V revision.

Redefining autism spectrum disorder using DSM-5: the implications of the proposed DSM-5 criteria for autism spectrum disorders.

Young, Robyn L; Rodi, Melissa L

2014-04-01

A number of changes were made to pervasive developmental disorders (PDDs) in the recently released diagnostic and statistical manual of mental disorders (APA, Diagnostic and statistical manual of mental disorders, American Psychiatric Publishing, Arlington, VA, 2013). Of the 210 participants in the present study who met DSM-IV-TR criteria for a PDD [i.e., autistic disorder, Asperger's disorder and pervasive developmental disorder-not otherwise specified (PDD-NOS)], only 57.1% met DSM-5 criteria (specificity = 1.0) for autism spectrum disorder when criteria were applied concurrently during diagnostic assessment. High-functioning individuals (i.e., Asperger's disorder and PDD-NOS) were less likely to meet DSM-5 criteria than those with autistic disorder. A failure to satisfy all three criteria in the social-communication domain was the most common reason for exclusion (39%). The implications of these results are discussed.

A number of studies have reported that parents of autistic children face higher levels of stress, but few studies examined the stress associated with the home care of children with pervasive developmental disorders (PDD) other than autistic disorder. The aims of the present study were therefore to (i) evaluate the emotional stress level of parents caring for their children with PDD; and (ii) explore the correlates of their emotional stress. Participants were 147 families (147 mothers and 122 fathers) of 158 children with PDD (42 with autistic disorder, 35 with Asperger's disorder and 81 with PDD not otherwise specified). K6 was used to measure the stress level of the parents. Marital relationships and personality were assessed with the Intimate Bond Measure and the NEO Five-Factor Inventory, respectively. The parents also rated the characteristics of their children with PDD through the Pervasive Developmental Disorder-Autism Society Japan Rating Scale (PARS). The mean K6 score of the mothers was significantly higher than that of the women in the general population in Japan. Stepwise multiple regression indicated that the emotional stress of the mothers was correlated with the personality traits of Neuroticism and Agreeableness, perceived Control by the husband, and the children's PARS score. Clinicians can deliver better service by paying appropriate attention to the emotional distress of mothers of children with not only autistic disorder but also other PDD.

PubMed

Schuntermann, Peter

2007-01-01

Parents raising a child with significant developmental challenges are profoundly aware of the often sustained impact of that child's special needs upon their other children. Supported by recent research on siblings of developmentally challenged children, clinicians are advocating family-based interventions that take into account the needs of siblings. This article reviews the experience of siblings who live with brothers or sisters diagnosed with pervasive developmental disorder or mental retardation. Contributions from research on typical siblings are drawn upon when appropriate. Six domains of the sibling experience are identified. These domains explore relational shifts within sibling relationships and through the expectable differential parental treatment of each child. Shifts considered in this review include the interrelationships with the extended family, peers, and friendships, all of which contribute to shaping the meaning that siblings give to living with developmentally challenged brothers or sisters across time.

Comorbidity in Pediatric Bipolar Disorder

Joshi, Gagan; Wilens, Timothy

2013-01-01

Synopsis A growing literature shows the pervasiveness and importance of comorbidity in youth with bipolar disorder (BPD). For instance, up to 90% of youth with BPD have been described to manifest comorbidity with attention deficit hyperactivity disorder. Multiple anxiety, substance use, and disruptive behavior disorders are the other most commonly reported comorbidities with BPD. Moreover, important recent data highlights the importance of obsessive compulsive and pervasive developmental illness in the context of BPD. Data suggests that not only special developmental relationships are operant in context to comorbidity, but also that the presence of comorbid disorders with BPD results in a more severe clinical condition. Moreover, the presence of comorbidity has therapeutic implications for the treatment response for both BPD and the associated comorbid disorder. Future longitudinal studies to address the relationship and the impact of comorbid disorders on course and therapeutic response over time are required in youth with BPD. PMID:19264265

[Asperger's syndrome: continuum or spectrum of autistic disorders?].

PubMed

Bryńska, Anita

2011-01-01

Pervasive Developmental Disorders (PPD) refers to the group of disorders characterised by delayed or inappropriate development of multiple basic functions including socialisation, communication, behaviour and cognitive functioning. The term,,autistic spectrum disorders" was established as a result of the magnitude of the intensity of symptoms and their proportions observed in all types of pervasive developmental disorders. Asperger's Syndrome (AS) remains the most controversial diagnosis in terms of its place within autism spectrum disorders. AS if often described as an equivalent of High Functioning Autism (HFA) or as a separate spectrum-related disorder with unique diagnostic criteria. Another important issue is the relationship between AS and speech disorders. Although it is relatively easy to draw a line between children with classical autism and speech disorders, the clear cut frontiers between them still remain to be found. The main distinguishing feature is the lack of stereotypic interests and unimpaired social interaction observed in children with speech disorders, such as semantic-pragmatic disorder.

Beck-Ripp, Julia Christiane; Dressel, Holger

2018-05-22

There is an ongoing discussion on the increasing number of children with mental and developmental disorders, with some even needing long-term care according to the German Social Code XI. This study was performed to identify the main diagnoses justifying such care in children and to analyse their prevalence over time. The diagnoses justifying long-term care were evaluated using care assessments of Bavarian children and adolescents between 2009 to 2014 by the medical service of statutory health insurance. Over the years investigated, the percentage of assessments due to a mental and behavioural disorder rose significantly from 36.2 to 42.2%. Since 2012, the most common diagnose changed from Down's syndrome to pervasive developmental disorders with marked increase of also mixed specific developmental disorders. In new applications for nursing insurance services the proportion of pervasive developmental disorders rose gradually from 151 in 2010 to 254 in 2014. During the whole period of time, the overall care dependency in children seemed to be stable. These observations might rather be influenced by altered awareness of health and illness, increasing readiness to seek help with psychological or developmental impairments as well as changed diagnostic criteria than by a steady increase in affected individuals. © Georg Thieme Verlag KG Stuttgart · New York.

Multiple complex developmental disorder (MCDD) is a well-defined and validated behavioural subtype of pervasive developmental disorder-not otherwise specified (PDD-NOS) and is thought to be associated with a higher risk of developing a schizophrenic spectrum disorder. The question was addressed whether patients with MCDD show the same psychophysiological abnormalities as seen in patients with schizophrenia. Smooth pursuit eye movement (pursuit gain and saccadic parameters) was measured in children with either MCDD (n=18) or autism (n=18), and in age- and IQ-matched controls (n=36), as well as in a group of adult patients with schizophrenia (n=14) and a group of adult controls (n=17). We found the expected effect of lower velocity gain and increased number of saccades in schizophrenic patients. Children with MCDD also showed a lower velocity gain compared to controls children. In contrast, velocity gain was similar in autistic subjects and controls. No differences for velocity gain were found in a direct comparison between MCDD and autism. Saccadic parameters were not significantly different from controls in either MCDD or autistic subjects. Children with MCDD, like schizophrenic adults, show a reduced velocity gain, which could indicate that schizophrenia spectrum disorders and MCDD share (at least to some degree) a common neurobiological background.

In diagnosing high-functioning PDD to adult patients, we should pay much attention to psychological consistency which exists between developmental problems in childhood, developed personality, recent problems in social adjustment, and manifested psychiatric symptoms. In order to understand these relationships, considering the patients' type of ego structure ("PDD ego type") seems to be useful. "PDD ego type" is characterized by their unique self-universe image which takes form of grid one (just like a touch panel), which is decisively different from the form of a radial or concentric circle held by most people (Jung, C.G). This self-universe image characterizes adult PDD patients' psychiatric symptoms, unsuitable social performance, and their "personality."

In the present study we investigated the co-morbidity of pervasive developmental disorder (PDD) in 59 Prader-Willi syndrome (PWS) individuals and in 59 non-specific mentally retarded controls, matched for IQ, gender, and age. The 'Pervasive Developmental Disorder Mentally Retardation Scale' (PDD-MRScale), a screening questionnaire based on the DSM-III-R criteria for PDD, has been applied in the PWS group and in the control group. Results of the present study revealed a striking autistic-like behavioral phenotype in the majority of the PWS individuals, particularly deficits in the quality of language and communication and of imagination and interests. This intersection with autistic symptomatology is an important addition to the behavioral phenotype in PWS persons. A first approach to delineate subtypes of autistic symptomalogy among PWS persons was performed. Nineteen percent of the PWS group did meet the full diagnostic DSM-III-R criteria for PDD in comparison with 15% in the control group. Results revealed that a higher IQ in PWS does not protect to develop genuine PDD and that uniparental disomy/imprinting mutation as genetic origin seems to be an additional risk factor for developing genuine PDD. The results of the present study suggest the importance of reconsidering the commonly recognized obsessive-compulsive like behavior in PWS persons within the broader spectrum of autism disorders.

[The effect of parent training program on children with attention deficit/hyperactivity disorders and/or pervasive developmental disorders].

PubMed

2012-07-01

Mothers of 18 children with attention deficit/hyperactivity disorders (AD/HD) and 6 with pervasive developmental disorders (PDD) underwent a parent training (PT) program. After the program, the Beck Depression Inventory- II (BDI - II) score, which indicates parenting stress, significantly decreased from 15 to 8 (p=0.036). A total of 22 mothers had increased parenting self-esteem, and better parent-child relationships were noted in these cases. An analysis of children's behavior by using Achenbach's Child Behavior Checklist showed that introversion tendency, physical failure, aggressive behavior, and extroversion score improved significantly after PT (p<0.05). After PT, out-of-control behaviors improved in 19 children and continued in 5. We conclude that PT for mothers of children with AD/HD and/or high-functioning PDD is effective in improving both the parenting skills of mothers and adaptive behaviors of children.

Purpose of review In the lead up to and following the recent publication of the DSM-5, the diagnostic construct of autism has received intense scrutiny. Recent findings This article briefly reviews the history of the diagnosis of autism, the changes that have occurred in the diagnosis over time, and the rationale for change. The most significant changes being introduced with the DSM-5 are highlighted, as well as some of the concerns that will be a focus of attention with respect to the potential impacts going forward. Summary The categorical divisions that characterized the pervasive developmental disorders are now collapsed into a single entity, autism spectrum disorder. The final DSM-5 criteria have yet to be formally compared prospectively against prior criteria, but early indications suggest that the boundaries around the pervasive developmental disorders have not been substantially altered.

We provide a systematic review of epidemiological surveys of autistic disorder and pervasive developmental disorders (PDDs) worldwide. A secondary aim was to consider the possible impact of geographic, cultural/ethnic, and socioeconomic factors on prevalence estimates and on clinical presentation of PDD. Based on the evidence reviewed, the median of prevalence estimates of autism spectrum disorders was 62/10 000. While existing estimates are variable, the evidence reviewed does not support differences in PDD prevalence by geographic region nor of a strong impact of ethnic/cultural or socioeconomic factors. However, power to detect such effects is seriously limited in existing data sets, particularly in low-income countries. While it is clear that prevalence estimates have increased over time and these vary in different neighboring and distant regions, these findings most likely represent broadening of the diagnostic concets, diagnostic switching from other developmental disabilities to PDD, service availability, and awareness of autistic spectrum disorders in both the lay and professional public. The lack of evidence from the majority of the world's population suggests a critical need for further research and capacity building in low- and middle-income countries.

Autism is defined as a neurologic developmental disorder affecting brain and behavior, becoming usually apparent before 3 years of age, with stable evolution and no remission. No neurologic morphologic abnormality was associated with the disease. Several types of disease being described, autism is part of a larger spectrum known as autism spectrum disorders (ASD), or pervasive developmental disorders (PDD). The disease was first described long before it was defined and it has received its modern name. Main cause in the development of autism is considered to be genetic, up to 90 %. However, environmental factors could be incriminated, sometimes. The five types included in ASD are: Asperger syndrome, pervasive developmental disorder-not otherwise specified (PDD-NOS), typical autism, Rett syndrome and childhood disintegrative disorder (CDD). The classical triad of symptoms includes: social interaction impairments, communication impairments and repetitive, stereotype behavior. Diagnosis is based on interview of the parents and specialized observation of the suspected children. Main tools used in therapy are the family and the educational system. Well established, specialized programs of therapy were developed in time. Prognosis of autism is severe, since no cure is possible; nevertheless spontaneous recoveries do occur, in some cases.

Hemispheric Processing of Idioms and Irony in Adults With and Without Pervasive Developmental Disorder.

PubMed

Saban-Bezalel, Ronit; Mashal, Nira

2015-11-01

Previous studies on individuals with pervasive developmental disorders (PDD) have pointed to difficulties in comprehension of figurative language. Using the divided visual field paradigm, the present study examined hemispheric processing of idioms and irony in 23 adults with PDD and in 24 typically developing (TD) adults. The results show that adults with PDD were relatively unimpaired in understanding figurative language. While the TD group demonstrated a right hemisphere advantage in processing the non-salient meanings of idioms as well as the ironic endings of paragraphs, the PDD group processed these stimuli bilaterally. Our findings suggest that brain lateralization is atypical in adults with PDD. Successful performance along with bilateral brain activation suggests that the PDD group uses a compensation mechanism.

Brief report: Representational momentum for dynamic facial expressions in pervasive developmental disorder.

PubMed

Uono, Shota; Sato, Wataru; Toichi, Motomi

2010-03-01

Individuals with pervasive developmental disorder (PDD) have difficulty with social communication via emotional facial expressions, but behavioral studies involving static images have reported inconsistent findings about emotion recognition. We investigated whether dynamic presentation of facial expression would enhance subjective perception of expressed emotion in 13 individuals with PDD and 13 typically developing controls. We presented dynamic and static emotional (fearful and happy) expressions. Participants were asked to match a changeable emotional face display with the last presented image. The results showed that both groups perceived the last image of dynamic facial expression to be more emotionally exaggerated than the static facial expression. This finding suggests that individuals with PDD have an intact perceptual mechanism for processing dynamic information in another individual's face.

Koyama, Tomonori; Inada, Naoko; Tsujii, Hiromi; Kurita, Hiroshi

2008-08-01

An original combination score (i.e. the sum of Vocabulary and Comprehension subtracted from the sum of Block Design and Digit Span) was created from the four Wechsler Intelligence Scale for Children-Third Edition (WISC-III) subtests identified by discriminant analysis on WISC-III data from 139/129 children with/without pervasive developmental disorders (PDD; mean, 8.3/8.1 years) and its utility examined for predicting PDD. Its best cut-off was 2/3, with sensitivity, specificity, positive and negative predictive values of 0.68, 0.61, 0.65 and 0.64, respectively. The score seems useful, so long as clinicians are aware of its limitations and use it only as a supplemental measure in PDD diagnosis.

The perisylvian areas, located around the Sylvian fissure, are constituted by frontal, temporal and parietal brain regions. These are connected forming specialized neural networks and play a primary role in the development of linguistic skills and social cognition. These areas are a possible neuronal substrate of cognitive and behavioral impairments in patients with autism spectrum disorders (ASD). To locate and quantify epileptiform activity sources through magnetoencephalography in frontal perisylvian areas in children with idiopathic ASD. Sixty-eight children with idiopathic ASD were studied by magnetoencephalography. The children were classified into two groups: a group of 41 children with autistic disorder and a combined group of 27 children with Asperger syndrome and children with pervasive developmental disorder not otherwise specified. The sources of magnetoencephalografic epileptiform activity detected in the frontal perisylvian were localized and quantified. The amount of epileptiform activity in frontal perisylvian region was significantly higher in children with autistic disorder. The amount of epileptiform activity in frontal perisylvian areas differed significantly between children with autistic disorder and those with Asperger syndrome and pervasive developmental disorder not otherwise specified.

Recognizing the Common Origins of Dystonia and the Development of Human Movement: A Manifesto of Unmet Needs in Isolated Childhood Dystonias

Lin, Jean-Pierre; Nardocci, Nardo

2016-01-01

Dystonia in childhood may be severely disabling and often unremitting and unrecognized. Considered a rare disorder, dystonic symptoms in childhood are pervasive in many conditions including disorders of developmental delay, cerebral palsy (CP), autism, neurometabolic, neuroinflammatory, and neurogenetic disorders. Collectively, there is a need to recognize the role of early postures and movements which characterize phases of normal fetal, infant, and child development as a backdrop to the many facets of dystonia in early childhood neurological disorders and to be aware of the developmental context of dystonic symptoms. The role of cocontraction is explored throughout infancy, childhood, young adulthood, and in the elderly. Under-recognition of pervasive dystonic disorders of childhood, including within CP is reviewed. Original descriptions of CP by Gowers are reviewed and contemporary physiological demonstrations are used to illustrate support for an interpretation of the tonic labyrinthine response as a manifestation of dystonia. Early recognition and molecular diagnosis of childhood dystonia where possible are desirable for appropriate clinical stratification and future precision medicine and functional neurosurgery where appropriate. A developmental neurobiological perspective could also be useful in exploring new clinical strategies for adult-onset dystonia disorders focusing on environmental and molecular interactions and systems behaviors.

Behavior change in a student with a dual diagnosis of deafness and pervasive developmental disorder: a case study.

PubMed

Easterbrooks, Susan R; Handley, C Michele

The broad term pervasive developmental disorder (PPD) describes a set of symptoms that occur along a continuum of severity; these symptoms are often referred to as autism spectrum disorders (ASDs). Little is known about the incidence and prevalence of ASDs among students who are deaf or hard of hearing (DHH). Teachers of DHH students, who must work with individuals with dual diagnoses, are at a loss for guidance from the literature. The authors review the literature on ASDs (also referred to as PDD) within the DHH population, provide results of a single-subject study to reduce PDD-type behaviors in a child with hearing loss, and argue that teachers of students who are DHH must learn about practices associated with applied behavior analysis as an tool for intervening therapeutically with children with dual diagnoses of hearing loss plus an ASD.

2007-10-11

Pervasive Developmental Disorders (PDD) are neurodevelopmental disorders characterized by impairments in social interaction, communication and behavior. Given the diversity and varying severity of PDD, diagnostic tools attempt to identify homogeneous subtypes within PDD. Identifying subtypes can lead to targeted etiology studies and to effective type-specific intervention. Cluster analysis can suggest coherent subsets in data; however, different methods and assumptions lead to different results. Several previous studies applied clustering to PDD data, varying in number and characteristics of the produced subtypes. Most studies used a relatively small dataset (fewer than 150 subjects), and all applied only a single clustering method. Here we study a relatively large dataset (358 PDD patients), using an ensemble of three clustering methods. The results are evaluated using several validation methods, and consolidated through an integration step. Four clusters are identified, analyzed and compared to subtypes previously defined by the widely used diagnostic tool DSM-IV.

2018-03-01

Recent studies have shown that individuals with neurodevelopmental disorders and their relatives have problems expressing and recognizing emotions, but there is a lack of studies on alexithymia, and the relationship between parental alexithymia and depression-anxiety symptoms in these groups. The aim of this study was therefore to measure alexithymia, depression, and anxiety levels in parents of children with pervasive developmental disorders and attention deficit-hyperactivity disorder (ADHD), and determine whether there is a positive correlation between the child's neurodevelopmental problem severity and parent scores. Parents of 29 autistic disorder (AD), 28 pervasive developmental disorder not otherwise specified (PDD-NOS) and 29 ADHD children were recruited into the study, and completed a demographic information form, as well as the Toronto Alexithymia Scale (TAS-20), Beck Depression Inventory, and State-Trait Anxiety Inventory. Alexithymia symptoms were higher in parents of children with AD than in others but unexpectedly, also these symptoms were higher in ADHD parents than in PDD-NOS groups. In addition, there were unexpected differences according to alexithymia subtype, while only the difference in maternal TAS-1 scores (difficulty in describing feelings) were statistically significant. Parental depression and state anxiety scores were increased as the child's symptom severity increased, but trait anxiety symptoms were higher in the AD and ADHD group than in the PDD-NOS group. In all groups, maternal depression and anxiety scores were higher than paternal scores, and differences were significant for depression and anxiety types in AD, and for only anxiety types in ADHD parents. The AD group had the strongest correlation between parental depression-anxiety and alexithymia. The possibility of alexithymia, depression and anxiety should be kept in mind when working with parents of children with neurodevelopmental disorders. © 2017 Japan Pediatric Society.

2008-04-01

The prevalence and pattern of criminal behaviour in a population of 313 former child psychiatric in-patients with pervasive developmental disorders were studied. The patients were divided into three subgroups and compared with 933 matched controls from the general population. Age at follow-up was between 25 years and 59 years. An account of convictions in the nationwide Danish Register of Criminality was used as a measure of criminal behaviour. Among 113 cases with childhood autism, .9% had been convicted. In atypical autism (n=86) and Asperger's syndrome (n=114) the percentages were 8.1% and 18.4%, respectively. The corresponding rate of convictions in the comparison groups was 18.9%, 14.7%, and 19.6% respectively. Particular attention is given to arson in Asperger's syndrome (p= .0009).

[On the benefits to keep using the asperger diagnosis].

PubMed

Delcommenne, M; Francolini, M; Bon, O L

The purpose of this paper is to examine the possible benefits to keep using the diagnosis of Asperger's syndrome. We first describe the evolution of this entity over time and within nomenclature bases such as the ICD- 10, the CFTMEA and the last versions of DSM. Then, we discuss more precisely the impact of the decision made in the DSM-5 to suppress the Asperger syndrome as a differentiated entity within the pervasive developmental disorders (PDD). This disorder chapter by the way also disappears and is replaced by Autism Spectrum Disorder (ASD). We present here three clinical cases encountered in an outpatient general child psychiatry clinic : 1 case was diagnosed as Asperger syndrome, 1 as infantile autism (early infantile autism) and 1 as another pervasive developmental disorder (psychotic disharmony). The objective was to expose the commonali ties and differences between these three entities. We conclude that keeping using the Asperger diagnosis is important for the clinical management of these clinical situations but also for the individual, his or her family and society at large.

Psychiatric diagnostic screening of social maladaptive behaviour in children with mild intellectual disability: differentiating disordered attachment and pervasive developmental disorder behaviour.

PubMed

Giltaij, H P; Sterkenburg, P S; Schuengel, C

2015-02-01

Children with intellectual disability (ID) are at risk for maladaptive development of social relatedness. Controversy exists whether Pervasive Developmental Disorder (PDD) takes precedence over disordered attachment for describing maladaptive social behaviour. The aim of this study was to assess the prevalence of disordered attachment symptoms in children with ID referred for mental health diagnosis, and to study the potential diagnostic overlap between symptoms of disordered attachment and PDD symptoms. Children (n = 102) in the age of 5-11 with IDs (borderline or mild; IQ 50-85) referred for psychiatric consultation were recruited. Parents were administered a screening interview for disturbances of attachment and teachers were administered a screening questionnaire for PDD. Behavioural symptoms of disordered attachment were reported for 42%* of the children, with 16%* showing symptoms of inhibited and 37%* showing symptoms of disinhibited attachment disorder. In 11% both types of symptoms were noted. Attachment disorder symptoms were not significantly associated with gender, ethnic background or age. Positive screening for PDD occurred for 27%. Positive screening for PDD was not significantly associated with symptoms of attachment disorder. Among children with ID referred for psychiatric consultation, Reactive Attachment Disorder (RAD) and PDD symptoms were both highly prevalent. RAD and PDD symptoms appear as distinct, but sometimes comorbid, forms of aberrant social relatedness.

DSM-5 ASD moves forward into the past.

Tsai, Luke Y; Ghaziuddin, Mohammad

2014-02-01

The fifth edition of the diagnostic and statistical manual of mental disorders (DSM-5) (APA in diagnostic and statistical manual of mental disorders, Author, Washington, 2013) has decided to merge the subtypes of pervasive developmental disorders into a single category of autism spectrum disorder (ASD) on the assumption that they cannot be reliably differentiated from one another. The purpose of this review is to analyze the basis of this assumption by examining the comparative studies between Asperger's disorder (AsD) and autistic disorder (AD), and between pervasive developmental disorder not otherwise specified (PDDNOS) and AD. In all, 125 studies compared AsD with AD. Of these, 30 studies concluded that AsD and AD were similar conditions while 95 studies found quantitative and qualitative differences between them. Likewise, 37 studies compared PDDNOS with AD. Nine of these concluded that PDDNOS did not differ significantly from AD while 28 reported quantitative and qualitative differences between them. Taken together, these findings do not support the conceptualization of AD, AsD and PDDNOS as a single category of ASD. Irrespective of the changes proposed by the DSM-5, future research and clinical practice will continue to find ways to meaningfully subtype the ASD.

Proposed changes to the American Psychiatric Association diagnostic criteria for autism spectrum disorder: implications for young children and their families.

PubMed

Grant, Roy; Nozyce, Molly

2013-05-01

The American Psychiatric Association has revised the diagnostic criteria for their DSM-5 manual. Important changes have been made to the diagnosis of the current (DSM-IV) category of Pervasive Developmental Disorders. This category includes Autistic Disorder (autism), Asperger's Disorder, and Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS). The DSM-5 deletes Asperger's Disorder and PDD-NOS as diagnostic entities. This change may have unintended consequences, including the possibility that the new diagnostic framework will adversely affect access to developmental interventions under Individuals with Disabilities Education Act (IDEA) programs, Early Intervention (for birth to 2 years olds) and preschool special education (for 3 and 4 years olds). Changing the current diagnosis of PDD-NOS to a "Social Communication Disorder" focused on language pragmatics in the DSM-5 may restrict eligibility for IDEA programs and limit the scope of services for affected children. Young children who meet current criteria for PDD-NOS require more intensive and multi-disciplinary services than would be available with a communication domain diagnosis and possible service authorization limited to speech-language therapy. Intensive behavioral interventions, inclusive group setting placements, and family support services are typically more available for children with an autism spectrum disorder than with diagnoses reflecting speech-language delay. The diagnostic distinction reflective of the higher language and social functioning between Asperger's Disorder and autism is also undermined by eliminating the former as a categorical diagnosis and subsuming it under autism. This change may adversely affect treatment planning and misinform parents about prognosis for children who meet current criteria for Asperger's Disorder.

Autism and autistic spectrum disorders in the context of new DSM-V classification, and clinical and epidemiological data.

PubMed

Stanković, Miodrag; Lakić, Aneta; Ilić, Neda

2012-01-01

Autism is one of disorders from the autism spectrum, besides Asperger syndrome, atypical autism and pervasive developmental disorder not otherwise specified. They are classified as mental disorders as being manifested by a wide range of cognitive, emotional and neurobehavioural abnormalities. Key categorical characteristics of the disorder are clear impairments of the development of the child's socialisation, understanding and production of verbal and non-verbal communication and restricted and repetitive patterns of behaviour. Demarcation boundaries are not clear, neither within the very group of the disorders from the autistic spectrum, nor with respect to the autistic behavioural features in the general population. For this reason, the term spectrum points out the significance of the dimensional assessment of autistic disorders, which will most likely be the basis of the new diagnostic classification of the disorders belonging to the current group of pervasive developmental disorders in the new DSM-V classification. The understanding, as well as the prevalence of the autistic spectrum disorders has changed drastically in the last four decades. From the previous 4 per 10,000 people, today's prevalence estimates range from 0.6 to around 1%, and the increase of prevalence cannot be explained solely by better recognition on the part of experts and parents or by wider diagnostic criteria. The general conclusion is that the autistic spectrum disorders are no longer rare conditions and that the approach aimed at acknowledging the warning that this is an urgent public health problem is completely justified.

These alterations have not previously been described in the scientific literature on Asperger syndrome.

Emerging Drugs for the Treatment of Symptoms Associated with Autism Spectrum Disorders

PubMed Central

Wink, Logan K.; Plawecki, Martin H.; Erickson, Craig A.; Stigler, Kimberly A.; McDougle, Christopher J.

2010-01-01

Importance of the Field Autism spectrum disorders, or pervasive developmental disorders (PDDs), are neurodevelopmental disorders defined by qualitative impairment in social interaction, impaired communication, and stereotyped patterns of behavior. The most common forms of PDD are autstic disorder (autism), Asperger's disorder, and pervasive developmental disorder not otherwise specified (PDD NOS). Recent surveillance studies reveal an increase in the prevalence of autism and related PDDs. The use of pharmacologic agents in the treatment of these disorders can reduce the impact of interfering symptoms, providing relief for affected individuals and their families. Areas Covered in this Review This review examines results from neurobiologic research in an attempt to both elucidate the pathophysiology of autism and guide the development of pharmacologic agents for the treatment of associated symptoms. The safety and efficacy data of drugs currently in clinical use for the treatment of these symptoms, as well as pharmaceuticals currently under development, are discussed. What the Reader will Gain This comprehensive review will deepen the reader's current understanding of the research guiding the pharmacologic treatment of symptoms associated with autism and related PDDs. Areas of focus for future research are also discussed. The need for large-scale investigation of some commonly used pharmacologic agents, in addition to the development of drugs with improved efficacy and safety profiles, is made evident. Take Home Message Despite progress in the development of pharmacologic treatments for a number of interfering symptom domains associated with autism and other PDDs, a great deal of work remains.

Pervasive developmental disorders: a 10-year review.

Tanguay, P E

2000-09-01

To summarize recent advances about the nature, diagnosis, and treatment of pervasive developmental disorders. Review of Medline databases, books, and book chapters published between July 1989 and November 1999. Clinical and genetic studies support expansion of the concept of autism to include a broader spectrum of social communication handicaps. The prevalence of autism is approximately 1 per 2,000; the prevalence of autism and Asperger's disorder together is 1 per 1,000. The Checklist for Autism in Toddlers is a useful screening instrument for 18-month-old children; the Autism Diagnostic Interview-Revised and the Autism Diagnostic Observation Schedule are instruments of choice for research. Although twin and family studies clearly support genetic factors as important in autism, linkage analysis studies indicate that many genes may be involved. There is no one treatment of choice. Social-pragmatic approaches, augmented by individualized strategies and social coaching, may be best for teaching social communication skills. Pharmacological interventions have a limited role in improving social communication, but selective serotonin reuptake inhibitors and atypical neuroleptic medications may help ameliorate aggression, hyperactivity, and other secondary problems. Private and government agencies must continue to support basic and applied research.

Extraction and Refinement Strategy for detection of autism in 18-month-olds: a guarantee of higher sensitivity and specificity in the process of mass screening.

For early detection of autism, it is difficult to maintain an efficient level of sensitivity and specificity based on observational data from a single screening. The Extraction and Refinement (E&R) Strategy utilizes a public children's health surveillance program to produce maximum efficacy in early detection of autism. In the extraction stage, all cases at risk of childhood problems, including developmental abnormality, are identified; in the refinement stage, cases without problems are excluded, leaving only cases with conclusive diagnoses. The city of Yokohama, Japan, conducts a routine child health surveillance program for children at 18 months in which specialized public health nurses administer YACHT-18 (Young Autism and other developmental disorders CHeckup Tool), a screening instrument to identify children at risk for developmental disorders. Children who screen positive undergo further observation, and those without disorders are subsequently excluded. To study the efficacy of early detection procedures for developmental disorders, including autism, 2,814 children born in 1988, examined at 18 months of age, and not already receiving treatment for diseases or disorders were selected. In the extraction stage, 402 (14.3%) children were identified for follow-up. In the refinement stage, 19 (.7%) of these were referred to the Yokohama Rehabilitation Center and diagnosed with developmental disorders. The extraction stage produced four false negatives, bringing total diagnoses of developmental disorders to 23 (.8%) - including 5 with autistic disorder and 9 with pervasive developmental disorder - not otherwise specified (PDDNOS). Sensitivity was 60% for autistic disorder and 82.6% for developmental disorders. Specificity for developmental disorders rose to 100% with the E&R Strategy. Picture cards used in YACHT-18 provided a finer screen that excluded some false positive cases. An extraction and refinement methodology utilizing child health surveillance programs achieve high efficacy for early detection of autism.

Autistic spectrum disorder: the challenge for dentists.

PubMed

Berman, Marvin H

2010-10-01

Those who actively work with children are, with increasing frequency, encountering patients who have been diagnosed with autistic disorders. Often, dentists may be the first healthcare providers to recognize that a 1- or 2-year-old child has some type of extraordinary pervasive behavioral disorder that a parent, fearing the worst, may have suspected instinctively and emotionally but never faced objectively. Currently, there are no empirical biological tests (eg, blood tests or brain scans) for ASD that are reliable. The definitive diagnosis of ASD is usually made by pediatricians, psychologists, or psychiatrists who institute a process of analysis which involves a developmental and clinical history, tests for cognitive function, and assessment of receptive and expressive language skills. The etiology of ASD is an enigma. Highly regarded researchers are of the opinion that there is probably more than one cause since the disorder can have such disparate manifestations. Genetics, environmental poisons, neurologic psychopathy, dietary deficiencies, and allergies have all been implicated. Pervasive developmental disorders, Asperger's syndrome, Rett syndrome, and childhood degenerative disorders are all considered a part of the ASD group, but the distinction between the various entities is not always clear. Given the fact that the etiology and the increased incidence of the various ASDs are scientifically puzzling, treatment modalities tend to be wide ranging and very much trial and error, especially since there is no cure. Dental professionals who treat patients with ASDs should be knowledgeable about the special needs of not only these patients, but also of their parents.

Pervasive developmental disorders among children and adolescents attending psychiatric day treatment.

Sverd, Jeffrey; Dubey, Dennis R; Schweitzer, Robert; Ninan, Remani

2003-11-01

This study sought to determine the prevalence of pervasive developmental disorders (PDD) among children admitted to a state hospital day treatment service and to characterize the psychiatric disturbance of patients with PDD. A total of 146 consecutively admitted patients were evaluated for PDD. Patients who had PDD were compared with a sample of age- and sex-matched patients in day treatment who did not have PDD. Psychiatric symptoms, family history, and developmental and educational histories were examined. Of the 146 patients, 20 (14 percent) met criteria for PDD. An additional five patients who had PDD were included, yielding a final sample of 25. Only two of an array of psychiatric symptoms were more prevalent among patients with PDD: engaging in unusual fantasy and talking to themselves, animals, or inanimate objects. Significantly more patients with PDD had a history of speech delay, language abnormalities, and inexplicable or lengthy episodes of crying or screaming. The groups did not differ significantly in IQ or global functioning. Seven patients with PDD (28 percent) met criteria for childhood-onset schizophrenia, and 19 (76 percent) had symptoms of a tic disorder. The study found that PDD is not rare and that children with PDD represent a significant subgroup of children with serious emotional disturbance referred for psychiatric treatment. The findings support the view that PDD may be easily missed because it may be mild and associated with psychiatric disturbances that are present among other severely ill youngsters.

Neurofeedback in autism spectrum disorders.

2011-11-01

To review current studies on the effectiveness of neurofeedback as a method of treatment of the core symptoms of autism spectrum disorders (ASD). Studies were selected based on searches in PubMed, Ovid MEDLINE, EMBASE, ERIC, and CINAHL using combinations of the following keywords: 'Neurofeedback' OR 'EEG Biofeedback' OR 'Neurotherapy' OR 'Mu-Rhythm' OR 'SMR' AND 'Autism' OR 'Autism Spectrum Disorder' OR 'Pervasive Developmental Disorder'. The existing evidence does not support the use of neurofeedback in the treatment of ASD. Studies with outcomes in favour of neurofeedback might be showing an improvement in comorbid attention-deficit-hyperactivity disorder symptoms rather than a true improvement in core ASD symptoms. Limitations of this review are those inherent in the studies available, including small sample size, short duration, variable diagnostic criteria, and insufficient control interventions, all causing a lack of generalizability. © The Authors.

Cosper, Sharon M; Lee, Gregory P; Peters, Susan Beth; Bishop, Elizabeth

2009-12-01

The objective of this study was to examine the efficacy of Interactive Metronome (Interactive Metronome, Sunrise, Florida, USA) training in a group of children with mixed attentional and motor coordination disorders to further explore which subcomponents of attentional control and motor functioning the training influences. Twelve children who had been diagnosed with attention deficit hyperactivity disorder, in conjunction with either developmental coordination disorder (n=10) or pervasive developmental disorder (n=2), underwent 15 1-h sessions of Interactive Metronome training over a 15-week period. Each child was assessed before and after the treatment using measures of attention, coordination, and motor control to determine the efficacy of training on these cognitive and behavioral realms. As a group, the children made significant improvements in complex visual choice reaction time and visuomotor control after the training. There were, however, no significant changes in sustained attention or inhibitory control over inappropriate motor responses after treatment. These results suggest Interactive Metronome training may address deficits in visuomotor control and speed, but appears to have little effect on sustained attention or motor inhibition.

Despite the increase in the incidence and prevalence rates of children and adolescents' mental disorders, there are few works performed with large and representative samples of children and adolescents with psychopathological symptoms. The present work analyses 588 participants referred by first care pediatricians to a specialized unit for children and adolescents' mental health. As a result of the study, a statistically significant relation was found between age and diagnosis: a larger incidence of behavioral disorders, communication disorders, elimination disorders, pervasive developmental disorders, impulse-control disorders from 0 to 5 years; behavioral disorders and attention deficit hyperactivity disorder (ADHD) were more common from 6 to 11 years, behavioral and anxiety disorders were more likely at 12 to 15 years; and, lastly, behavioral disorders were more prevalent from 16 to 18 years. With respect to gender, there was a significant relationship with diagnosis: boys had more behavioral disorders, whereas girl had more anxiety disorders. To conclude, a relationship between mental disorders and developmental achievements could be indicated in the younger group. Additionally, externalizing disorders in boys and internalizing ones n girls were more prevalent across all ages.

Maternal impulse control disability and developmental disorder traits are risk factors for child maltreatment.

Previous work has suggested that maternal developmental disorder traits related to autism spectrum disorder (ASD) and attention-deficit hyperactivity disorder (ADHD) are significantly associated with child maltreatment. However, there may be other important maternal characteristics that contribute to child maltreatment. We hypothesized that maternal impulse control disability may also affect child maltreatment in addition to maternal developmental disorder traits. We aimed to test this hypothesis via a cohort study performed in Tokyo (n = 1,260). Linear regression analyses using the Behavioural Inhibition/Behavioural Activation Scales, the self-administered short version of the Pervasive Developmental Disorders Autism Society Japan Rating Scale, the short form of the Adult Attention-Deficit Hyperactivity Disorder Self-Report Scale, and the Child Maltreatment Scale, revealed that excessive inhibition of behaviour and affect, which is impulse control disability, is significantly associated with child maltreatment (b = 0.031, p = 0.018) in addition to maternal developmental disorder traits (ASD: b = 0.052, p = 0.004; ADHD: b = 0.178, p < 0.001). Logistic regression analyses revealed that ASD (adjusted odds ratio [AOR] = 1.083, p = 0.014) and high behavioural inhibition (AOR = 1.068, p = 0.016) were significantly associated with moderate child maltreatment, while ADHD was associated (AOR = 1.034, p = 0.022) with severe child maltreatment. These maternal characteristics may inform the best means for prevention and management of child maltreatment cases.

The objective of the study was to investigate the associations among maternal prepregnancy BMI, paternal BMI, and the risk of autism spectrum disorders (ASDs) in children. The study sample of 92 909 children was derived from the population-based, prospective Norwegian Mother and Child Cohort Study. The age range was 4.0 through 13.1 (mean 7.4) years. Relative risks of ASDs were estimated by odds ratios (ORs) and 95% confidence intervals (CIs) from logistic regression models. At the end of follow-up on December 31, 2012, 419 children in the study sample had been diagnosed with ASDs: 162 with autistic disorder, 103 with Asperger disorder, and 154 with pervasive developmental disorder not otherwise specified. Maternal obesity (BMI ≥30) was only weakly associated with ASD risk, whereas paternal obesity was associated with an increased risk of autistic disorder and Asperger disorder. The risk of autistic disorder was 0.27% (25 of 9267) in children of obese fathers and 0.14% (59 of 41 603) in children of fathers with normal weight (BMI <25), generating an adjusted OR of 1.73 (95% CI: 1.07-2.82). For Asperger disorder, analyses were limited to children aged ≥7 years (n = 50 116). The risk was 0.38% (18 of 4761) in children of obese fathers and 0.18% (42 of 22 736) in children of normal-weight fathers, and the adjusted OR was 2.01 (95% CI: 1.13-3.57). No associations were found for pervasive developmental disorder not otherwise specified. Paternal obesity is an independent risk factor for ASDs in children. The associations should be investigated further in genetic and epigenetic studies. Copyright © 2014 by the American Academy of Pediatrics.

While conventional wisdom has always affirmed the value of animals in promoting human health and well-being, only recently has their therapeutic role in medicine become a topic for dedicated research. Animal assisted interventions (AAI) can be classified as animal-assisted activities, animal-assisted therapy, and service animal programs. The aim of this review is to analyse original papers addressing AAI and neurological diseases and published in the most influential medical journals between 2001 and 2012, and discuss their findings in the light of what may be of interest in the field of neurology. We selected a total of 23 articles on neurorehabilitation in cerebral palsy, pervasive developmental disorders, multiple sclerosis, spinal cord injury, stroke, and mental disorders. The main therapeutic results were improvement on the Gross Motor Function Classification Scale and in upper limb dexterity (cerebral palsy); improvement in social functioning and interaction; reductions in stress, anxiety, and loneliness (pervasive developmental disorders and mental disorders); and decreased spasticity with improved balance (multiple sclerosis, spinal cord injury, stroke). These interventions, performed with highly specialised animals in very specific neurological populations, deliver an increasing body of scientific evidence suggesting that they are an effective complement to other existing therapies. In these diseases, further high-quality studies are warranted in order to define the most appropriate programmes for therapy. Copyright © 2012 Sociedad Española de Neurología.

2016-10-01

This study compared the number of attention deficit hyperactivity disorder (ADHD) cases defined by Diagnostic and Statistical Manual (DSM)-IV versus DSM-V criterion in children who have learning or behavioral problems with high IQ. The medical records of children ≤15 years of age who presented with learning or behavioral problems and underwent a Wechsler Intelligence Scale for Children (WISC)-III IQ test at the Pediatric Outpatient Clinic unit between 2010 and 2015 were reviewed. Information on DSM-IV and DSM-V criteria for ADHD were derived from computer-based medical records. Twenty-eight children who had learning or behavioral problems were identified to have a full-scale IQ ≥120. Sixteen of these high-IQ children met the DSM-IV criteria diagnosis for ADHD. Applying the extension of the age-of-onset criterion from 7 to 12 years in DSM-V led to an increase of three cases, all of which were the inattentive type ADHD. Including the pervasive developmental disorder criterion led to an increase of one case. The total number of ADHD cases also increased from 16 to 20 in this group. The data supported the hypothesis that applying the extension of the age-of-onset ADHD criterion and enabling the diagnosis of children with pervasive developmental disorders will increase the number of ADHD diagnoses among children with high IQ. © The Author(s) 2016.

Psychomotor development and psychopathology in childhood.

PubMed

de Raeymaecker, Dirk M J

2006-01-01

The sensorimotor developmental phase, leading to a gradual acquisition of skilled actions, is of crucial importance for the young child and its growing sense of competence. Three vital steps in motor development are mentioned: first, the smooth and spontaneous movements of the "graceful and elegant" baby, expression of his well-being and vitality, with their profound effect on the mother-infant relationship; second, the emergence of intentional and goal-oriented acts leading to Funktionslust and playful repetitions; and finally, the development of symbolic acts and increasing technical capacity to use playthings in imaginative play. The psychodynamic significance of the most important motor milestones for the child's ego development is set out. Motility is one of the most important avenues for exercising such functions as mastery, integration, reality testing (self-preservation), and control of impulses. One may consider this early childhood period of rapid motor development as the motor phase of ego and libido development. Hence, many forms of developmental psychopathology are attended with motor impairment or insufficient motor mastery and integration. From that clinical perspective pass in review: perinatal complications and motor disturbance, attention deficit/hyperactivity disorder, dissociated motor development, low birth weight children and their developmental difficulties, developmental coordination disorder, aspects of pervasive developmental disorder, and stereotypic movement disorder.

2016-06-01

Changes to the DSM-5 Autism Spectrum Disorder (ASD) criteria raised concerns among parents and practitioners that the criteria may exclude some children with Pervasive Developmental Disorder (PDD). Few studies have examined DSM-5 sensitivity and specificity in children less than 5 years of age. This study evaluated 185 children aged 20-55 months with DSM-IV PDD or developmental delay. Autism Diagnostic Interview-Revised (ADI-R) and Autism Diagnostic Observation Schedule (ADOS) data was assigned to DSM-5 subdomains. Children displaying the required symptomatology were classified with DSM-5 ASD. DSM-IV clinical diagnoses were compared to DSM-5 classifications. Using combined ADI-R/ADOS information, sensitivity was .84 and specificity was .54. Comorbid behaviour and emotional problems were significantly lower in children with PDD that did not meet DSM-5 criteria.

2012-01-01

The article presents the Polish version of the autism diagnostic observation schedule-generic (ADOS), which together with the autism diagnostic interview-revised (ADI-R) is cited as the "gold standard" for the diagnosis of autism. The ADOS is a standardised, semistructured observation protocol appropriate for children and adults of differing age and language levels. It is linked to ICD-10 and DSM-IV-TR criteria. The ADOS consists of four modules, ranging from module 1 for nonverbal individuals to module 4 for verbally fluent adults. The adequate inter-rater reliability for items has been established. The protocol has high discriminant validity and distinguishes children with pervasive developmental disorders from children, who are outside of the spectrum. Although it does not enable to distinguish individuals with pervasive developmental disorder, unspecified from individuals with childhood autism. The paper presents subsequent steps of the translation process of the original version into Polish, as well as a chosen adaptation strategy of the Polish version. The ADOS is a very useful tool both for clinical diagnosis and for the scientific purpose diagnosis. In this last case it is extremely important to use a standardised method. Until now, there was no standardised diagnostic tool for autism in Poland.

Neurobiological research has implicated the dopamine and serotonin systems in the pathogenesis of autism. Open-label reports suggest that the serotonin2A-dopamine D2 antagonist risperidone may be safe and effective in reducing the interfering symptoms of patients with autism. Thirty-one adults (age [mean+/-SD], 28.1+/-7.3 years) with autistic disorder (n=17) or pervasive developmental disorder not otherwise specified (n=14) participated in a 12-week double-blind, placebo-controlled trial of risperidone. Patients treated with placebo subsequently received a 12-week open-label trial of risperidone. For persons completing the study, 8 (57%) of 14 patients treated with risperidone were categorized as responders (daily dose [mean+/-SD], 2.9+/-1.4 mg) compared with none of 16 in the placebo group (P<.002). Risperidone was superior to placebo in reducing repetitive behavior (P<.001), aggression (P<.001), anxiety or nervousness (P<.02), depression (P<.03), irritability (P<.01), and the overall behavioral symptoms of autism (P<.02). Objective, measurable change in social behavior and language did not occur. Nine (60%) of 15 patients who received treatment with open-label risperidone following the double-blind placebo phase responded. Other than mild, transient sedation, risperidone was well tolerated, with no evidence of extrapyramidal effects, cardiac events, or seizures. Risperidone is more effective than placebo in the short-term treatment of symptoms of autism in adults.

A long delay between the first registered symptoms of autism spectrum disorder and a final diagnosis has been reported. The reasons for this are the spare use of specialized autism instruments, missing clinical expertise, and the late referral to specialized centers in primary care. Previous studies recommending the Child Behavior Checklist 1.5-5 for screening have requested additional research. A total of 183 children aged 25-71 months participated in this study. The Child Behavior Checklist scales of 80 children with autism spectrum disorder were compared with 103 children diagnosed with other psychiatric disorders. In the logistic regression analysis, the Withdrawn and Pervasive Developmental Problems Child Behavior Checklist scales with a significant predictive value of risk for an autism spectrum disorder diagnosis were identified. The optimal cutoff points T = 64.5 on the Pervasive Developmental Problems scale (area under the curve = 0.781, sensitivity = 0.83, specificity = 0.60, positive predictive value = 0.62, negative predictive value = 0.82, odds ratio = 7) and T = 60.5 on the Withdrawn scale (area under the curve = 0.809, sensitivity = 0.88, specificity = 0.63, positive predictive value = 0.65, negative predictive value = 0.87, odds ratio = 12) were evaluated in the receiver operating characteristics analysis. The present study confirms the utility of the German version of the Child Behavior Checklist 1.5-5 as a level 1 screening tool to identify children with a risk of autism spectrum disorder; however, a risk of over-identifying should be considered. The Child Behavior Checklist 1.5-5 can complement the pediatric examination as a quick and cost-effective questionnaire.

Autism Spectrum Disorder Updates - Relevant Information for Early Interventionists to Consider.

PubMed

Allen-Meares, Paula; MacDonald, Megan; McGee, Kristin

2016-01-01

Autism spectrum disorder (ASD) is a pervasive developmental disorder characterized by deficits in social communication skills as well as repetitive, restricted or stereotyped behaviors (1). Early interventionists are often found at the forefront of assessment, evaluation, and early intervention services for children with ASD. The role of an early intervention specialist may include assessing developmental history, providing group and individual counseling, working in partnership with families on home, school, and community environments, mobilizing school and community resources, and assisting in the development of positive early intervention strategies (2, 3). The commonality among these roles resides in the importance of providing up-to-date, relevant information to families and children. The purpose of this review is to provide pertinent up-to-date knowledge for early interventionists to help inform practice in working with individuals with ASD, including common behavioral models of intervention.

Autism is a pervasive developmental disorder, with impairments in reciprocal social interaction and verbal and nonverbal communication. There is often the need of psychopharmacological intervention in addition to psychobehavioral therapies, but benefits are limited by adverse side effects. For that reason, Panax ginseng, which is comparable with Piracetam, a substance effective in the treatment of autism, was investigated for possible improvement of autistic symptoms. There was some improvement, which suggests some benefits of Panax ginseng, at least as an add-on therapy.

The Restricted, Repetitive Behaviours and Interests (RRBIs) are represented in the DSM-IV and measured by the Autism Diagnostic Interview-Revised (ADI-R) as one of the three homogeneous symptom categories of Pervasive Developmental Disorders. Although this conceptualisation is well accepted in the field, the grouping of symptoms is based primarily on clinical judgment rather than on empirical evidence. The objective of this study was to examine the factor structure of the RRBI domain of autism. Eleven items from this domain of the ADI-R were used in a Principal Components Analysis (PCA). Our sample consisted of 339 individuals with a Best Estimate diagnosis of Pervasive Developmental Disorder (PDD). Findings indicate that the RRBI domain is composed of two distinct factors or dimensions: Insistence on Sameness (IS) and Repetitive Sensory and Motor Behaviours (RSMB). RSMB is negatively correlated with adaptive skills; that is, lower functioning individuals tend to have higher levels of repetitive sensory and motor behaviours. On the other hand, IS is positively correlated with autistic symptoms in the communication and language domain. Further analyses suggest moderate familial aggregation among affected sibling pairs within the IS but not the RSMB factor. These results provide evidence for the heterogeneity of the RRBI domain of the ADI-R in terms of both clinical presentation and other correlates. In addition, the IS factor seems to be under familial (presumably genetic) control, while RSMB appears to simply reflect variation in developmental level.

Sleep physiology and sleep disorders in childhood

2011-01-01

Sleep has long been considered as a passive phenomenon, but it is now clear that it is a period of intense brain activity involving higher cortical functions. Overall, sleep affects every aspect of a child’s development, particularly higher cognitive functions. Sleep concerns are ranked as the fifth leading concern of parents. Close to one third of all children suffer from sleep disorders, the prevalence of which is increased in certain pediatric populations, such as children with special needs, children with psychiatric or medical diagnoses and children with autism or pervasive developmental disorders. The paper reviews sleep physiology and the impact, classification, and management of sleep disorders in the pediatric age group. PMID:23616721

As many as six in every 1000 children may be affected by an autistic spectrum disorder. The previous article of this two-part series discussed the distinction between autism, Asperger's syndrome and pervasive developmental disorder, and examined the assessment process. This article looks at potential differential diagnoses that must be considered, as well as conditions associated with autism. Many theories about the causes of autism have been suggested, including the MMR vaccine. Recent research has suggested that there is no link between the vaccine and autism. There is no cure for autism, but intervention and management techniques should be aimed at educating parents and carers about the disorder and behavioural interventions to aid the child's skills development.

[Autism in children. Speech, behavior and motor activity point to diagnosis].

2001-02-01

Austistic disorders characteristically involve specific impairments of social skills, of the language and of stereotyped body movements. L Kanner and H. Asperger were the first to describe these psychopathologic features, which still form the core of the diagnostic criteria of contemporary psychiatric classification systems, ICD-10 and DSM-IV, in the category pervasive developmental disorders. Useful diagnostic tools have been developed to establish the clinical diagnosis. The results of research point to a predominantly genetic pathogenesis involving a complex interaction of multiple genes. While no causal treatments are available for these heterogenic disorders, there are many therapeutic concepts. Although some treatments may achieve significant improvements, autistic disorders usually mean a lifelong individual impairment.

There are currently only two psychotropics approved by the FDA to treat irritability in the autistic population. This drug profile will discuss available studies of aripiprazole in individuals with pervasive developmental disorders, two of which led to its recent FDA approval. We will discuss the efficacy, as well as the safety and tolerability of the drug documented in these studies. In addition, the chemistry, pharmacokinetics, metabolism and mechanism of action of aripiprazole will be reviewed. PMID:21359119

Contradictory studies suggest that some neonatal factors may be associated with a pervasive developmental disorder (PDD) diagnosis, but limited data is available from longitudinal, prospective medical record assessments. The present hypothesis-testing longitudinal, case-control study evaluated birth characteristics among cases diagnosed with a PDD in comparison to controls by examining prospectively collected automated medical records within the Vaccine Safety Datalink (VSD) database. Cases were Health Maintenance Organization (HMO)-enrolled from birth until diagnosed with International Classification of Disease, 9th revision (ICD-9) PDD (299.xx) and controls were HMO-enrolled from birth for at least 4.75 years without a PDD diagnosis. The birth characteristics examined included: gender, gestational age in weeks at birth, mean birth weight in grams, Appearance-Pulse-Grimace-Activity-Respiration (APGAR) scores at 1 minute and 5 minutes, and maternal age in years at birth. Cases had a significantly increased male/female ratio relative to controls. By contrast, mean gestational age at birth, mean birth weight, mean maternal age at birth, and mean APGAR scores at 1 minute and 5 minutes were not statistically different among cases compared to controls. This study indicates that cases diagnosed with a PDD as compared to controls do not have significant differences in neonatal factors.

The focus of this study is using data glove to practice Joint attention skill in virtual reality environment for people with pervasive developmental disorder (PDD). The virtual reality environment provides a safe environment for PDD people. Especially, when they made errors during practice in virtual reality environment, there is no suffering or dangerous consequences to deal with. Joint attention is a critical skill in the disorder characteristics of children with PDD. The absence of joint attention is a deficit frequently affects their social relationship in daily life. Therefore, this study designed the Joint Attention Skills Learning (JASL) systems with data glove tool to help children with PDD to practice joint attention behavior skills. The JASL specifically focus the skills of pointing, showing, sharing things and behavior interaction with other children with PDD. The system is designed in playroom-scene and presented in the first-person perspectives for users. The functions contain pointing and showing, moving virtual objects, 3D animation, text, speaking sounds, and feedback. The method was employed single subject multiple-probe design across subjects' designs, and analysis of visual inspection in this study. It took 3 months to finish the experimental section. Surprisingly, the experiment results reveal that the participants have further extension in improving the joint attention skills in their daily life after using the JASL system. The significant potential in this particular treatment of joint attention for each participant will be discussed in details in this paper. Copyright © 2012 Elsevier Ltd. All rights reserved.

Patterns of Early Skill Attainment and Loss in Young Children with Autism

The purpose of this study was to extend the literature on the ontogeny of autism spectrum disorder (ASD) by examining early attainment and loss of specific sociocommunicative skills in children with autism (AUT; n = 125), pervasive developmental disorder not otherwise specified (PDD-NOS; n = 42), nonspectrum developmental delays (n = 46), and typical development (n = 31). The ages of skill attainment and loss were obtained from a caregiver interview. The findings indicated that children with AUT, PDD-NOS, and developmental delays diverged from typically developing children in attainment of sociocommunicative skills early in the first year of life. Loss of at least one skill was reported in a majority of children with AUT and PDD-NOS. Significant delays in attainment of skills were also reported in children who lost skills. The wide variation in skill attainment and loss reported across children indicates that symptom onset and regression may be best represented continuously, with at least some early delay and loss present for a great majority of children with ASD.

2005-02-01

The origin and developmental course of stereotypic and self-injurious behaviour among individuals with developmental disabilities such as intellectual disability (ID) or pervasive development disorders such as autism is not well understood. Twelve studies designed to document the prevalence, nature, or development of stereotypic and/or self-injurious behaviour in children under 5 years of age and identified as at risk for developmental delay or disability were reviewed. Comparisons were made with similar studies with typically developing children. It appears that the onset of naturally occurring rhythmic motor stereotypies is delayed in young at-risk children, but that the sequencing may be similar. A very small database, differences in samples, measures, and designs limited the degree to which comparisons could be made across studies. Future work is needed based on appropriately designed prospective comparison studies and uniform quantitative measures to provide an empirical basis for new knowledge about the early development of one of the most serious behaviour disorders afflicting children with ID and related problems of development.

Designing affective video games to support the social-emotional development of teenagers with autism spectrum disorders.

PubMed

Khandaker, Mitu

2009-01-01

Autism spectrum disorders (ASD) are a group of developmental neuropsychiatric disorders, comprised of three diagnostic entities - autistic disorder (AD), Asperger's disorder (AS), and Pervasive Developmental Disorder Not Otherwise Specified (including atypical autism) (PDD-NOS). A number of intervention techniques are currently used to reduce some of the associated challenges, with techniques ranging from behavioral therapy to dietary interventions and traditional counseling. This positional paper proposes the use of video games which leverage affective computing technologies as intervention in autism spectrum disorders in the context of the use of traditional play therapy with adolescents, who may feel uncomfortable engaging in traditional play with toys they may be too old for. It aims to explore the potential for greater 'social physics' made possible by affective computing technologies. This involves computationally 'recognizing' emotions in a user, often through the use of multimodal affective sensors, including facial expressions, postural shifts, and physiological signals such as heart rate, skin conductivity, and EEG signals. However, it is suggested that this should be augmented by researching the effect of social game design mechanisms on social-emotional development, particularly for those who experience difficulty with social interaction.

This article gives an overview of the consultant child and adolescent psychiatric services in the region of Upper Bavaria (Germany). The data of 257 children and adolescents with intellectual disability and psychiatric disorders were evaluated. About 14% of the children with ID in special schools or day care centers, and 40% of the children with ID in residential care showed a definite psychiatric disorder. The most frequently diagnosed disorders were adjustment disorders, hyperkinetic disorders and conduct disorders, as well as emotional problems and pervasive developmental disorders. Children with severe intellectual disability had more additional somatic disorders and were more impaired in their psychosocial functions. The results show the need for psychiatric services for children and adolescents with intellectual disability and psychiatric disorders. The development and implementation of integrative and interdisciplinary models is necessary to allow for adequate medical care for these patients.

Due to the recent inclusion of Asperger's Disorder (AD) in the Diagnostic and Statistical Manual of Mental Disorders (APA, 1994) and the International Classification of Diseases (WHO, 1993), concerns regarding diagnosis of AD, particularly in adults, are emerging. Many existing instruments used to assess Pervasive Developmental Disorder are more appropriate for identifying Autistic Disorder (AU) in children, and their usefulness for assessing AD in adults is questionable. We describe and critically review five instruments created specifically for identifying AD in adults. Overall, the normative information provided is limited and evidence of the reliability and validity for each instrument is relatively poor. Further research and development is required before we would recommend one instrument over another for the assessment of AD in adults.

To describe the last 5 years' experience of Child Development Centre (CDC), Kerala Developmental Evaluation Clinic II for children between 2 and 10 y, referred for suspicion of developmental lag in the preschool years and scholastic difficulty in the primary classes with specific focus on developmental profile and the experience of the home based intervention package taught to the mothers. A team of evaluators including developmental therapist, preschool teacher with special training in clinical child development, speech therapist, special educator, clinical psychologist and developmental pediatrician assessed all the children referred to CDC Kerala. Denver Developmental Screening Test (DDST-II), Vineland Social Maturity Scale (VSMS) and Intelligent Quotient (IQ) tests were administered to all children below 6 y and those above 6 with apparent developmental delay. Speech/delay (35.9%), behavior problem (15.4%), global delay/ intellectual disability (15.4%), learning problem (10.9%), pervasive developmental disorders (7.7%), seizure disorder (1.7%), hearing impairment (0.7%), and visual impairment (0.7%) were the clinical diagnosis by a developmental pediatrician. Each child with developmental problem was offered a home based intervention package consisting of developmental therapy and special education items, appropriate to the clinical diagnosis of the individual child and the same was taught to the mother. The experience of conducting the developmental evaluation clinic for children between 2 and 10 y has shown that a team consisting of developmental therapist, speech therapist, preschool teacher, special educator, clinical child psychologist and developmental pediatrician, using appropriate test results of the child could make a clinical diagnosis good enough for providing early intervention therapy using a home based intervention package.

Neurocognitive accounts of developmental dyscalculia and its remediation.

PubMed

Iuculano, T

2016-01-01

Numbers are one of the most pervasive stimulus categories in our environment and an integral foundation of modern society. Yet, up to 20% of individuals fail to understand, represent, and manipulate numbers and form the basis of arithmetic, a condition termed developmental dyscalculia (DD). Multiple cognitive and neural systems including those that serve numerical, mnemonic, visuospatial, and cognitive control functions have independently been implicated in the etiology of DD, yet most studies have not taken a comprehensive or dynamic view of the disorder. This chapter supports the view of DD as a multifaceted neurodevelopmental disorder that is the result of multiple aberrancies at one or multiple levels of the information processing hierarchy, which supports successful arithmetic learning, and suggests that interventions should target all these systems to achieve successful outcomes, at the behavioral and neural levels. © 2016 Elsevier B.V.

To investigate the link between autism disorders and engineering training of parents. All Autistic-Pervasive Developmental Disorders (PDD) children that were diagnosed on the bases of the Diagnostic and Statistical Manual for Mental Disorders (DSM-IV), and met the required criteria for autism, over a defined period (March 2006 to June 2007) were included. We then took all non-PDD developmental disorders cases seen during the same time frame as the autistic children as a control; these included speech delay, mental retardation, and Down's syndrome. Our data covered demographic data, parents and grandparents' education, and profession. Parents' education/professions were classified into 2 groups only, 1-engineering or mathematician; and 2-humanities, neither engineering nor math. The children were divided into 2 groups, autism (57 cases), and developmental disorders (40 cases). Regarding the main question of this study (hypothesized engineering link), the data showed some differences between the 2 groups (x2 = 2.503, degrees of freedom [df] = 1; p = 0.093), but not of major significance. There was no significant difference (x2 = 0.370; df = 2; p = 0.831) between the 2 groups on the variable of consanguinity. We have found that the Saudi Arabian sample, though relatively small, has considerable similarities with both the UK and USA data. There is a possibility of an association between autism and the engineering/math training of fathers. The implication is briefly discussed.

[Specific developmental disorder of speech and language in adulthood].

PubMed

Vlassopoulos, M; Anagnostopoulos, D C

2012-06-01

Specific developmental disorder of speech and language is part of a more general category of neurodevelopmental disorders, which is encountered in 7-10% of the childhood population. These children exhibit a significant impairment in speech and language development, which cannot be justified by hearing impairment, cognitive impairment, neuromuscular or orofacial disorders, as well as by emotional or environmental factors. Specific developmental disorders of speech and language are often comorbid with other neurodevelopmental disorders, such as motor coordination disorder and ADHD. These disorders are usually detected in early childhood and commonly treated during the preschool and school years. Despite this fact clinical and empirical evidence suggest that often these disorders persist beyond the school years, even though the symptomatology may be differentiated. In this literature review, we address the question of whether specific developmental language disorders are encountered only during childhood, and, if they persist, how they are manifested in adulthood. Finally, possible factors which may lead to these manifestations are analyzed. A considerable body of research has shown that even though the symptoms of children with specific developmental language disorders are resolved before the end of childhood, a significant part of this population continues to have persisting difficulties through adolescence and into adulthood. The continuity of this disorder may sometimes be directly linked to language disorder, as in the case of learning impairments or, on the other hand, symptoms may be related with those of conduct disorders, social adjustment disorder, emotional and psychiatric disorders in adolescence and adulthood. It therefore appears that specific developmental language disorder is often an early symptom of other disorders in the future. Even though the precise mechanisms which are responsible for these disorders are not yet known, it is possible that a fragile neurobiological substratum in these disorders may explain why early symptoms are usually manifested as language disorders and later develop into other disorders over time. However, these symptom changes may be linked to other parameters, such as the increasing social and emotional demands made on these individuals with increasing age, which may be a contributing environmental parameter to an already vulnerable system. Despite all of the limitations in the longterm study of these children, it is suggested that in some way, and not in all cases, pathology may continue into adulthood, although with a different symptomatology, which is linked to behavioural and social adjustment, as well as with more pervasive psychiatric disorders. In conclusion, it is suggested that a continuum of services may be necessary for these cases into adulthood.

PubMed

Martinez, G; Cook-Darzens, S; Chaste, P; Mouren, M-C; Doyen, C

2014-04-01

Anorexia nervosa is a serious psychiatric disorder, for which very few validated therapeutic strategies exist. The specific sociocognitive style of anorexic patients has already been described in the 1960s: it involves a concrete style with abstraction difficulties. Current neuropsychological tests have contributed to a more precise definition of these difficulties. IS THERE A SPECIFIC COGNITIVE PROFILE?: Contrary to common beliefs, these patients' intellectual performances are not superior to those of the general population. However, detailed comparisons of profiles on the Weschler Scales suggest difficulties in synthesizing information and better abilities in concrete problem solving. The dominant hypothesis concerning the attentional dimension is the existence of a weakness in central coherence, resulting in superior detail processing and a weakness in global integration. This trend appears to be stable even after the normalization of nutritional status. The impairment of set-shifting abilities leads to rigidity, expressed by inflexibility and perseveration, both in reasoning and behaviour. This reduced cognitive flexibility appears to persist after recovery, and may constitute a familial trait. In addition, this likely endophenotype seems to be independent from obsessional traits. Alexithymia is frequently described in anorexic individuals. It is the verbal description of feelings which seems to be particularly impaired. It may explain underlying difficulties in empathy. Indeed, these subjects have lower scores on emotional tests drawn from the theory of mind. These cognitive abnormalities are well documented in pervasive developmental disorders. NEUROANATOMICAL DATA: NEUROIMAGING IN SUPPORT OF LIMBIC AND FRONTO-STRIATAL ABNORMALITIES: Evidence from neuroimaging suggests abnormalities in cortical and subcortical structures, involving the temporal and orbito-frontal lobes. Various functional hypotheses are formulated, involving fronto-striatothalamic circuits, amygdala or insula. IS ANOREXIA NERVOSA A DEVELOPMENTAL DISORDER?: Pervasive developmental disorders are over-represented among anorexic subjects in comparison to the general population. Conversely, restrictive and selective eating disorders are more frequent among individuals presenting an autistic spectrum disorder. In view of the common cognitive and neuroanatomical data that are found in anorexia nervosa and neurodevelopmental disorders, we adhere to the hypothesis that anorexia nervosa may be similar to a neurodevelopmental disorder. Clinical observations suggest that this hypothesis may be especially relevant in the early forms of anorexia nervosa. These cognitive data confirm the potential relevance of new therapeutic modalities such as cognitive remediation. Initial results from its application to anorexia nervosa seem promising. A review of the recent literature highlights the possible existence of a developmental impairment of cortical and subcortical structures, associated with specific abnormalities in cognitive development such as a weakness in central coherence, reduced set-shifting ability and poor social skills. On this basis, cognitive remediation may be a promising therapeutic innovation. Copyright © 2013. Published by Elsevier Masson SAS.

Parent Report of Community Psychiatric Comorbid Diagnoses in Autism Spectrum Disorders

2011-01-01

We used a national online registry to examine variation in cumulative prevalence of community diagnosis of psychiatric comorbidity in 4343 children with autism spectrum disorders (ASD). Adjusted multivariate logistic regression models compared influence of individual, family, and geographic factors on cumulative prevalence of parent-reported anxiety disorder, depression, bipolar disorder, and attention deficit/hyperactivity disorder or attention deficit disorder. Adjusted odds of community-assigned lifetime psychiatric comorbidity were significantly higher with each additional year of life, with increasing autism severity, and with Asperger syndrome and pervasive developmental disorder—not otherwise specified compared with autistic disorder. Overall, in this largest study of parent-reported community diagnoses of psychiatric comorbidity, gender, autistic regression, autism severity, and type of ASD all emerged as significant factors correlating with cumulative prevalence. These findings could suggest both underlying trends in actual comorbidity as well as variation in community interpretation and application of comorbid diagnoses in ASD. PMID:22937248

We investigated a consecutive series of children with chronic enterocolitis and regressive developmental disorder. 12 children (mean age 6 years [range 3-10], 11 boys) were referred to a paediatric gastroenterology unit with a history of normal development followed by loss of acquired skills, including language, together with diarrhoea and abdominal pain. Children underwent gastroenterological, neurological, and developmental assessment and review of developmental records. Ileocolonoscopy and biopsy sampling, magnetic-resonance imaging (MRI), electroencephalography (EEG), and lumbar puncture were done under sedation. Barium follow-through radiography was done where possible. Biochemical, haematological, and immunological profiles were examined. Onset of behavioural symptoms was associated, by the parents, with measles, mumps, and rubella vaccination in eight of the 12 children, with measles infection in one child, and otitis media in another. All 12 children had intestinal abnormalities, ranging from lymphoid nodular hyperplasia to aphthoid ulceration. Histology showed patchy chronic inflammation in the colon in 11 children and reactive ileal lymphoid hyperplasia in seven, but no granulomas. Behavioural disorders included autism (nine), disintegrative psychosis (one), and possible postviral or vaccinal encephalitis (two). There were no focal neurological abnormalities and MRI and EEG tests were normal. Abnormal laboratory results were significantly raised urinary methylmalonic acid compared with age-matched controls (p=0.003), low haemoglobin in four children, and a low serum IgA in four children. We identified associated gastrointestinal disease and developmental regression in a group of previously normal children, which was generally associated in time with possible environmental triggers.

Developmental amnesia: a new pattern of dissociation with intact episodic memory.

PubMed

Temple, Christine M; Richardson, Paul

2004-01-01

A case of developmental amnesia is reported for a child, CL, of normal intelligence, who has intact episodic memory but impaired semantic memory for both semantic knowledge of facts and semantic knowledge of words, including general world knowledge, knowledge of word meanings and superordinate knowledge of words. In contrast to the deficits in semantic memory, there are no impairments in episodic memory for verbal or visual material, assessed by recall or recognition. Lexical decision was also intact, indicating impairment in semantic knowledge of vocabulary rather than absence of lexical representations. The case forms a double dissociation to the cases of Vargha-Khadem et al. [Science 277 (1997) 376; Episodic memory: new directions in research (2002) 153]; Gadian et al. [Brain 123 (2000) 499] for whom semantic memory was intact but episodic memory was impaired. This double dissociation suggests that semantic memory and episodic memory have the capacity to develop separately and supports models of modularity within memory development and a functional architecture for the developmental disorders within which there is residual normality rather than pervasive abnormality. Knowledge of arithmetical facts is also spared for CL, consistent with adult studies arguing for numeracy knowledge distinct from other semantics. Reading was characterised by difficulty with irregular words and homophones but intact reading of nonwords. CL has surface dyslexia with poor lexico-semantic reading skills but good phonological reading skills. The case was identified following screening from a population of normal schoolchildren suggesting that developmental amnesias may be more pervasive than has been recognised previously.

The transition from DSM-IV to DSM-5 criteria for autism spectrum disorder (ASD) sparked considerable concern about the potential implications of these changes. This study was designed to address limitations of prior studies by prospectively examining the concordance of DSM-IV and final DSM-5 criteria on a consecutive sample of 439 children referred for autism diagnostic evaluations. Concordance and discordance were assessed using a consistent diagnostic battery. DSM-5 criteria demonstrated excellent overall specificity and good sensitivity relative to DSM-IV criteria. Sensitivity and specificity were strongest for children meeting DSM-IV criteria for autistic disorder, but poor for those meeting criteria for Asperger's disorder and pervasive developmental disorder. Higher IQ, older age, female sex, and less pronounced ASD symptoms were associated with greater discordance.

Neuropsychological functioning of 30 siblings of children with autism (AU-S), 28 siblings of children with mental retardation of (MR-S), and 30 siblings of children with developmental language delay (DLD-S) was compared. Two siblings, both AU-S, received diagnoses of pervasive developmental disorder (PDD). More siblings with cognitive disabilities were found in DLD-S than in AU-S. However, these differences disappeared after excluding diagnosed siblings or after accounting for family membership. In sum, despite the elevated incidence of PDD among AU-S, the neuropsychological functioning of the remaining siblings did not convey specific characteristics related to the genetic risk associated with autism, in contrast to the cognitive functioning of the DLD-S, which did reflect a genetic risk.

Despite recent interest in the pathogenesis of the autism spectrum disorders (pervasive developmental disorders), neuropathological descriptions of brains of individuals with well documented clinical information and without potentially confounding symptomatology are exceptionally rare. Asperger syndrome differs from classic autism by lack of cognitive impairment or delay in expressive language acquisition. We examined the 1,570 g brain of a 63 year old otherwise healthy mathematician with an Autistic Spectrum Disorder of Asperger subtype. Except for an atypical gyral pattern and megalencephaly, we detected no specific neuropathologic abnormality. Taken together, the behavioral data and pathological findings in this case are compatible with an early neurodevelopmental process affecting multiple neuroanatomic networks, but without a convincing morphologic signature detectable with routine neuropathologic technology.

Silberg, Judy L; Bulik, Cynthia M

2005-12-01

We investigated the role of genetic and environmental factors in the developmental association among symptoms of eating disorders, depression, and anxiety syndromes in 8-13-year-old and 14-17-year-old twin girls. Multivariate genetic models were fitted to child-reported longitudinal symptom data gathered from clinical interview on 408 MZ and 198 DZ female twin pairs from the Virginia Twin Study of Adolescent Behavioural Development (VTSABD). Model-fitting revealed distinct etiological patterns underlying the association among symptoms of eating disorders, depression, overanxious disorder (OAD), and separation anxiety disorder (SAD) during the course of development: 1) a common genetic factor influencing liability to all symptoms - of early and later OAD, depression, SAD, and eating symptoms; 2) a distinct genetic factor specifically indexing liability to early eating disorders symptoms; 3) a shared environmental factor specifically influencing early depression and early eating disorders symptoms; and 4) a common environmental factor affecting liability to symptoms of later eating disorders and both early and later separation anxiety. These results suggest a pervasive genetic effect that influences liability to symptoms of over-anxiety, separation anxiety, depression, and eating disorder throughout development, a shared environmental influence on later adolescent eating problems and persistent separation anxiety, genetic influences specific to early eating disorders symptoms, and a shared environmental factor influencing symptoms of early eating and depression.

Comorbidity of Asperger's syndrome and Bipolar disorder

PubMed Central

2008-01-01

Background and objective Asperger's Syndrome (AS) is a pervasive developmental disorder that is sometimes unrecognized, especially in the adult psychiatric setting. On the other hand, in patients with an AS diagnosis, comorbid psychiatric disorders may be unrecognized in the juvenile setting. The aim of the paper is to show and discuss some troublesome and complex problems of the management of patients with AS and comorbid Bipolar Disorder (BD). Methods The paper describes three patients affected by AS and bipolar spectrum disorders. Results and conclusion Mood stabilizers and 2nd generation antipsychotics were effective in the treatment of these AS patients with comorbid BD, while the use of antidepressants was associated with worsening of the mood disorder. It is of importance to recognize both the psychiatric diagnoses in order to arrange an exhaustive therapeutic program and to define specific and realistic goals of treatment. PMID:19014623

Pervasive Developmental Disorder (PDD) is characterized by peculiar psycho-behavioral patterns. Youths with PDD who commit delinquent acts often exhibit strange behavior beyond ordinary comprehension. In order to fully understand and identify PDD it is important to take a comprehensive psychosocial history. Here we report on a 19-year-old delinquent male from a juvenile detention home who was exhibiting PDD. Both the psycho-behavioral patterns of the subject and the dysfunctional family background were key factors in this case. The subject persistently stalked and harassed an elementary school girl despite repeated intervention by police and the girl's parents to stop doing so. This behavior culminated in the subject being arrested and put on probation. While on probation his behavior continued, leading to his arrest and confinement to a correctional facility for juveniles with medical needs. Several features that included sustained impairment in social interaction and repetitive patterns of behavior that are often identified in delinquents with PDD were found to exist in the subject and he was diagnosed with PDD (probably Asperger's disease). The subject presented with a superficial understanding of the consequences his behavior had on others and for himself. Also, impaired family function was found to be a major contributing factor to his delinquency. Together theses factors hindered the subject from acquiring appropriate social skills. The major responsibility for providing care and support of an individual with PDD is within the family. Failure of the family to undertake such responsibilities can lead to ineffective treatment even after a specialist has identified the disorder. Given the slow decline of the nuclear family in Japan, it is important to understand the role of the family in caring for a child with PDD. Also, public recognition of PDD and social support for individuals with the disorder is important.

Purpose This study assessed medication use and associated costs among 8- and 15-yearold children with autism spectrum disorders (ASD) identified by the South Carolina Autism and Developmental Disabilities Monitoring (SCADDM) Network. Methods All Medicaid-eligible SCADDM-identified children with ASD from surveillance years 2006 and 2007 were included (n=263). Children were classified as ASD cases when documented behaviors consistent with the DSM-IV-TR criteria for autistic disorder, Asperger disorder, or pervasive developmental disorder- not otherwise specified (PDD-NOS) were present in health and education evaluation records. Medication and cost data were obtained by linking population-based and Medicaid data. Results All 263 SCADDM-identified children had Medicaid data available; 56% (n=147) had a prescription of any type, 40% (n=105) used psychotropic medication, and 20% (n=52) used multiple psychotropic classes over the study period. Common combinations were (1) attention deficit hyperactivity disorder (ADHD) medications and an antihypertensive, antidepressant or antipsychotic; and (2) antidepressants and an antipsychotic. Multiple psychotropic classes were more common among older children. Both the overall distribution of the number of prescription claims and medication costs varied significantly by age. Conclusions Results confirm that medication use in ASD, alone or in combination, is common, costly, and may increase with age. PMID:22153288

In clinical practice, pharmacological treatment is mostly focused on behavioral symptoms in everyday life. Nevertheless, persistent effort continues to develop medication for causal treatment. Recent changes in diagnostic criteria from Diagnostic and Statistical Manual of Mental Disorders, 4th edition, text revision (DSM-IV-TR) to DSM-5 would affect not only diagnosing approaches, but also therapeutic approaches. Because previous pervasive developmental disorders have been integrated into a single entity, the autism spectrum disorder (ASD), we have to prepare for what medications are valuable for the ASD. In this article, we reviewed the following etiological treatment: acetylcholine and glutamate related medicine; amino acid medicine such as secretin, endogenous opioid, and oxytocin; complementary and alternative medicine such as chelating agents, vitamins, and omega-3; promising drugs related to the scope of pharmacogenetics currently under study.

PubMed

Aussilloux, C; Baghdadli, A

2008-05-01

Although Asperger syndrome is described by international classifications as a category of pervasive developmental disorder (PDD), its validity as a specific entity distinct from autistic disorders remains controversial. The syndrome, first described by Hans Asperger, could not be distinguished from high functioning autism (onset, symptoms, outcome...). However, international classifications propose a distinction between the two syndromes based on a delayed onset, the absence of speech delay, the presence of motor disorders and a better outcome in Asperger syndrome. This categorical differentiation is not confirmed by current studies and in the absence of biological markers, no clinical, neuropsychological or epidemiological criteria makes it possible to distinguish high functioning autism from Asperger syndrome. From a clinical perspective, it is nevertheless of interest to isolate Asperger syndrome from other autistic disorders to propose specific assessment and therapy.

Early development in males with Fragile X syndrome: a review of the literature.

This article reviews the current bibliographic knowledge on early neurobehavioral development and milestones in Fragile X syndrome (FraX), with emphasis on males affected by the condition. Three broad areas of early development were examined: (1) gross and fine motor, (2) speech and language, and (3) social. The result of the current review indicates very limited information on the developmental milestones in all three areas. The scarce literature on motor development shows that in FraX there is an early developmental delay. Research on speech and language demonstrates pervasive deficits in conversational skills and severe developmental delay, with increasing discrepancy between language level and chronological age in young males with FraX. Finally, deficits in social development in FraX include abnormal gaze, approach and avoidance conflict, and high incidence of autistic spectrum disorders. Copyright 2002 Wiley-Liss, Inc.

[Gender dysphoria in pervasive developmental disorders].

PubMed

Tateno, Masaru; Ikeda, Hiroshi; Saito, Toshikazu

2011-01-01

Pervasive developmental disorders (PDD) are characterized by two essential symptoms: impairment in social interaction, and restricted, repetitive, and stereotyped patterns of behavior, interests, and activities. PDD include autistic disorder, Asperger's disorder, and PDD-Not Otherwise Specified (PDD-NOS). These three disorders are sometimes termed autism spectrum disorders. A recent epidemiological survey demonstrated that the rate of PDD may be almost 1% and that many PDD cases might not be diagnosed properly in childhood. Erik Erikson described eight stages of psychosocial development through which a normally developing human should pass from infancy to adulthood. In the theory, an adolescent shows 'Identity vs. Role Confusion'. It has been reported that individuals with PDD often have identity crises which sometimes include gender dysphoria. This phenomenon might be related to the so-called identity diffusion in youth. When they reach their young youth, it has been said that subjects with PDD realize their uniqueness and differences compared to others, and, as a result, they may develop confusion of identity which could be exhibited as gender identity disorder. A recent study demonstrated that, amongst 204 children and adolescents who visited a GID clinic in the Netherlands, 7.8% were diagnosed with autism spectrum disorders after a careful diagnostic procedure by a multi-disciplinary team. Taken together, PDD and GID seem closely related to each other. In this paper, we present four PDD cases with gender dysphoria and related symptoms: 1) a girl with PDD who repeatedly asserted gender identity disorder (GID) symptoms in response to social isolation at school, 2) a junior high school boy with PDD and transvestism, 3) a boy diagnosed with Asperger's disorder who developed a disturbance of sexual orientation, and 4) a boy with Asperger's disorder and comorbid childhood GID. Many of the clinical symptoms related to gender dysphoria might be explained by the cognitive characteristics and psychopathology of PDD. The Japanese Society of Psychiatry and Neurology published guidelines for the assessment and treatment of GID in 1997, and revised them in 2006. As a result, GID has become well known as a clinical entity in Japan, and there have been an increasing number of Japanese patients complaining of gender dysphoria. It is important to consider an underlying diagnosis of PDD when encountering patients with gender dysphoria.

Post-traumatic Stress in Children and Adolescents Exposed to Family Violence: I. Overview and Issues

Exposure to child physical abuse and parents’ domestic violence can subject youth to pervasive traumatic stress and lead to Post-traumatic Stress Disorder (PTSD). The often repeating and ongoing nature of family violence exposure may result in youth exhibiting problems in multiple domains of functioning and meeting criteria for multiple disorders in addition to PTSD. These characteristics as well as unique factors related to children’s developmental level and symptom presentation complicate a PTSD diagnosis. This paper describes evolving conceptualizations in the burgeoning field of trauma related to family violence exposure, and reviews considerations that inform assessment and treatment planning for this population.

The case of a 5-year-old child diagnosed as having pervasive developmental disorder (PDD), autistic type, from age 1 is reported. After surgery of vegetation in middle ear for repetitive otitis, the child presented an improvement in autistic behaviours, previously expressed as impaired social interactions, qualitative abnormalities in communication, a marked delay in language development, echolalia, stereotypies and self-aggressive behaviours. The aim of this paper is to bring attention to occurrences of misdiagnosis of PDD, which can occur when an adequate screening of the autistic syndrome is not realised. The result of the surgery was an improvement in autistic behaviours, despite the persistence of less severe autistic traits that may be more closely related to Asperger’s syndrome. PMID:22736729

The first experiment involved 143 individuals with severe and profound mental retardation. Individuals with Stereotypic Movement Disorder, Self-Injurious Behavior (SIB), and Stereotypic movement disorder with self-injurious behavior as assessed by the Diagnostic Assessment for the Severely Handicapped-II DASH-II were validated against Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV; American Psychiatric Association, 1994) criteria. In a second study DASH-II scores for 1480 individuals with severe and profound mental retardation were compared on demographic variables, core and associated features of each disorder. Characteristics of persons in each group were reviewed. Persons with profound mental retardation were more likely to evince stereotypies or self-injury compared to their severely impaired counterparts. Also, those with stereotypies were more likely to present with Pervasive Developmental Disorder (PDD)/autism, organicity, and eating disorders, while persons with SIB were more likely to evince sleep, sexual, and eating disorders.

To examine various pre-, peri-, and neonatal factors in autistic participants and in pervasive developmental disorder-not otherwise specified (PDD-NOS) participants and to compare the incidence of each factor to that of the normal population. Seventy-four participants (66 males, 8 females) were diagnosed with autism at 2.5 through 4 years of age using the most accurate and up-to-date methods, including the Diagnostic and Statistical Manual of Mental Disorders and the Autism Diagnostic Interview-Revised. At age 5, all participants were reevaluated using the Diagnostic and Statistical Manual of Mental Disorders, the Autism Diagnostic Interview-Revised, the Childhood Autism Rating Scale, and the Autism Diagnostic Observation Schedule-Revised, resulting in 61 autistic and 13 PDD-NOS participants. Twenty-eight pre-, peri-, and neonatal factors were examined in these 2 groups using both medical records and parental interviews. Incidences were compared with those of the US population as reported in the Report of Final Natality Statistics, 1995. This grand scale population group was used to closely approximate comparison to a normal, unbiased population. Results were analyzed using the binomial probability test, with a P value of <.05, constituting a significant difference in incidence. A Bonferroni correction was applied to the data to adjust for the number of factors investigated. Although most of the factors showed comparable incidences between the index and control groups, several factors showed statistically significant differences. Following the Bonferroni correction, the autism group was found to have a significantly higher incidence of uterine bleeding, a lower incidence of maternal vaginal infection, and less maternal use of contraceptives during conception when compared with the general population. Similarly, the PDD-NOS group showed a higher incidence of hyperbilirubinemia when compared with the general population. The results of this study support previous findings suggesting a consistent association of unfavorable events in pregnancy, delivery, and the neonatal phase and the pervasive developmental disorders. However, interpretation of the meaningfulness of these results is difficult, as the specific complications that carried the highest risk of autism and PDD-NOS represented various forms of pathologic processes with no presently apparent unifying feature. Additional studies are needed to corroborate and strengthen these associations, as well as to determine the possibility of an underlying unifying pathological process. This study's analysis of obstetric and neonatal complications in combination with the use of participants diagnosed at an early age provides some interesting concepts to consider. Perhaps future research will confirm certain pre-, peri-, and neonatal associations that could be used to generate a high-risk historical profile with which to use in conjunction with currently employed diagnostic tools. This may, in turn, help to determine the reliability of a diagnosis of autism in younger children, leading to earlier intervention and assistance for an improved outcome in long-term functionality and quality of life.

Personality disorder across the life course.

PubMed

Newton-Howes, Giles; Clark, Lee Anna; Chanen, Andrew

2015-02-21

The pervasive effect of personality disorder is often overlooked in clinical practice, both as an important moderator of mental state and physical disorders, and as a disorder that should be recognised and managed in its own right. Contemporary research has shown that maladaptive personality (when personality traits are extreme and associated with clinical distress or psychosocial impairment) is common, can be recognised early in life, evolves continuously across the lifespan, and is more plastic than previously believed. These new insights offer opportunities to intervene to support more adaptive development than before, and research shows that such intervention can be effective. Further research is needed to improve classification, assessment, and diagnosis of personality disorder across the lifespan; to understand the complex interplay between changes in personality traits and clinical presentation over time; and to promote more effective intervention at the earliest possible stage of the disorder than is done at present. Recognition of how personality disorder relates to age and developmental stage can improve care of all patients. Copyright © 2015 Elsevier Ltd. All rights reserved.

The first aim of this study was to evaluate the association between different subgroups of autism spectrum disorders (ASDs) (childhood autism, Asperger syndrome, and pervasive developmental disorder/pervasive developmental disorder - not otherwise specified [PDD/PDD-NOS]) and congenital anomalies. Second, we assessed the association among intellectually disabled children with ASDs in the subgroups of childhood autism and PDD/PDD-NOS. Nationwide population-based register data for children with a diagnosis of ASD (n=4449; 3548 males, 901 females) were collected during years 1987-2000 from the Finnish Hospital Discharge Register. Data on congenital anomalies were derived from the National Register of Congenital Malformations. Conditional logistic regression models were used as a statistical method. The association between ASD subgroups and congenital anomalies was stratified by the presence or absence of intellectual disability. Congenital anomalies occurred more frequently in all subgroups of ASD than in comparison participants (adjusted odds ratio [OR] for major congenital anomalies 1.8, 95% confidence interval [CI] 1.5-2.2, p<0.001). The association between congenital anomalies and childhood autism (OR 2.4, 95% CI 1.6-3.6, p<0.001) and between congenital anomalies and PDD/PDD-NOS (OR 3.7, 95% CI 2.4-5.7, p<0.001) among children with an intellectual disability was strong but remained significant also without intellectual disability (childhood autism: OR 1.7, 95% CI 1.3-2.3, p<0.001; PDD/PDD-NOS: OR 2.3, 95% CI 1.9-2.8, p<0.001). The results suggest a significant association between ASDs and congenital anomalies regardless of the ASD subgroup. The association between childhood autism and PDD/PDD-NOS and congenital anomalies is stronger among children with intellectual disability is stronger than among those without intellectual disability. These results may have relevance in examining early risk factors in autism during fetal neurodevelopment. © 2014 Mac Keith Press.

To evaluate the results of the Pervasive Developmental Disorders (PDD) screening program currently ongoing in the public health services in the health area of Salamanca and Zamora, Spain, in terms of feasibility, reliability and costs, with the purpose of extending the program at regional and national levels. A total of 54 paediatric teams (nurses and paediatricians) from the provinces of Salamanca and Zamora participated in the training sessions for the PDD Screening Programme in September 2005, and agreed to administer the questionnaire M-CHAT(1) to all parents attending their clinics in any of these two visits: 18 months and/or 24 months within the Well-baby Check-up Program. A total of 9,524 children have participated up to December 2012. Additionally, we evaluated the participation and opinions of the paediatric teams using questionnaires, and costs per positive case have estimated. Out of a total of 852 (8.9%) children determined as PDD high-risk with the M-CHAT questionnaire results, 61 (7.1%) were confirmed as positive with the M-CHAT follow-up interview. Of these, 22 were diagnosed with a PDD and 31 other disorders of childhood onset according to DSM-IV-TR(2). Almost three-quarters (74%) of respondents felt the program was totally feasible, and 22% viable, but with reservations (n=54). This study has been able to show for the first time in Spain, the feasibility of a population-based PDD screening program within the public health system. Training in social and communicative development, and dissemination of the early signs of PDD among paediatricians, as well as the use of the M-CHAT, is essential for progress in the early detection of these disorders.

Abstract Objective The aim of this study was to determine the effectiveness and tolerability of aripiprazole for irritability in pervasive developmental disorder not otherwise specified (PDD-NOS) and Asperger's disorder. Method This is a 14-week, prospective, open-label investigation of aripiprazole in 25 children and adolescents diagnosed with PDD-NOS or Asperger's disorder. Primary outcome measures included the Clinical Global Impressions–Improvement (CGI-I) scale and the Irritability subscale of the Aberrant Behavior Checklist (ABC-I). Results Twenty-five subjects, ages 5–17 years (mean 8.6 years) received a mean final aripiprazole dosage of 7.8 mg/day (range 2.5–15 mg/day). Full-scale intelligence quotient (IQ) scores ranged from 48 to 122 (mean 84). Twenty-two (88%) of 25 subjects were responders in regard to interfering symptoms of irritability, including aggression, self-injury, and tantrums, with a final CGI-I of 1 or 2 (very much or much improved) and a 25% or greater improvement on the ABC-I. The final mean CGI-I was 1.6 (p ≤ 0.0001). ABC-I scores ranged from 18 to 43 (mean 29) at baseline, whereas scores at week 14 ranged from 0 to 27 (mean 8.1) (p ≤ 0.001). Aripiprazole was well tolerated. Mild extrapyramidal symptoms (EPS) were reported in 9 subjects. Age- and sex-normed body mass index (BMI) increased from a mean value of 20.3 at baseline to 21.1 at end point (p ≤ 0.04). Prolactin significantly decreased from a mean value of 9.3 at baseline to 2.9 at end point (p ≤ 0.0001). No subject exited the study due to a drug-related adverse event. Conclusions These preliminary data suggest that aripiprazole may be effective and well tolerated for severe irritability in pediatric patients with PDD-NOS or Asperger's disorder. Larger-scale placebo-controlled studies are needed to elucidate the efficacy and tolerability of aripiprazole in this understudied population. PMID:19519261

[A case of pervasive developmental disorder with chromosomal translocation (X; 4) (p11; q13)].

PubMed

Azzoni, A; Raja, M

2006-01-01

Chromosomal aberrations, with or without congenital physical abnormalities, have been frequently found associated with neuropsychiatric disorders, including mental retardation, psychosis, autism, and criminal behaviour. The meaning of the association frequently remains unclear. However, consistent findings of association between specific chromosomal abnormalities and clinical phenotype may provide evidence of a causal relationship and shed light on the pathogenesis of obscure disorders. Here, we present the case of a 28 year-old, Caucasian male affected by pervasive developmental disorder, associated with chromosomal translocation 46, XY, t (X; 4) (p11; q13), and abnormal facial features. A few days after birth, the patient was taken away from his parents and adopted for unknown reasons. No information is available about his biological relatives. Mild delay in the development of spoken language was reported. Since early childhood, the patient's behaviour was characterized by troublesome relationship with his parents and his fellows, and persistent violation of norms and rules at home and at school. Consequently, social and school functioning was poor. When he was eight, verbal and motor stereotypy appeared for the first time. As an adolescent, he was more and more aggressive. He exhibited countless episodes of rage and verbal and physical aggressiveness. After he had completed secondary school, his way of life was chaotic. He got into the habit of staying away from home, sleeping in the day and vagabonding at night. He began to abuse alcohol. Grandiosity and persecutory delusions became evident. He claimed to hate the Vatican, the Pope, and the Polish people and to be the Devil, the Antichrist. He feared that his food was poisoned by his mother and refused to eat at home any more. He loved to remain in a cage with two wild dogs, accumulating and keeping bottles full of his urine. He often engaged in violent fights in the street with tramps and foreigners. Finally, he was involuntary admitted to a psychiatric intensive care unit. He was hostile, uncooperative, and violent. Magnetic resonance imaging of brain was normal, Wechsler Adult Intelligence Scale IQ score was 96 (total), 108 (verbal), 80 (non verbal), and Standard Progressive Matrices score was 44/60, chromosomal examination [banding R (RBG)] revealed an apparently balanced translocation 46, XY, t (X; 4) (p11; q13). The patient was treated with risperidone (8 mg/day) and valproate (1500-2000 mg/day) with improvement. Psychotic symptoms, hostility and violence vanished. Amazingly, his behaviour and attitude became normal. Very early onset of symptoms, absence of negative signs, and dysmorphic features suggesting an underlying medical disease do not support the diagnosis of schizophrenia. The diagnosis of pervasive developmental disorder, not otherwise specified, could be made, considering the delay in the development of spoken language, the large discordance between verbal and non verbal WAIS IQ score, the presence of stereotypy, abnormal facial features, and motor clumsiness. The late onset of symptoms precludes the diagnosis of autism, while the delay in language does not permit the diagnosis of Asperger's disorder. The lack of information on his biological relatives did not permit us to assess the presence of genetic, physical or mental abnormalities in his family. Therefore, the causal relationship between the chromosomal translocation and the psychiatric disorder is uncertain in this patient. Similar genetic abnormalities found in patients affected by neuropsychiatric disorders could confirm an etiological link.

Autistic-like findings associated with a urea cycle disorder in a 4-year-old girl

2005-01-01

A 4-year-old girl presented at our clinic with autistic-like symptoms, aggressivity and occasional hyperactivity. She had no history of neurologic or physical symptoms. Her condition was diagnosed as pervasive developmental disorder not otherwise specified, according to the criteria of the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV). She received pharmacologic (thioridazine), educational and speech therapy. During this process, a urea cycle disorder was also identified, namely, ornithine transcarbamylase deficiency and arginase deficiency, because of the high level of ammonia in the patient's bloodstream, the high level of organic acids in the 24-hour urine collection and the constant presence of slow multifocal epileptic discharges on the electroencephalograms.

A 4-year-old girl presented at our clinic with autistic-like symptoms, aggressivity and occasional hyperactivity. She had no history of neurologic or physical symptoms. Her condition was diagnosed as pervasive developmental disorder not otherwise specified, according to the criteria of the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV). She received pharmacologic (thioridazine), educational and speech therapy. During this process, a urea cycle disorder was also identified, namely, ornithine transcarbamylase deficiency and arginase deficiency, because of the high level of ammonia in the patient's bloodstream, the high level of organic acids in the 24-hour urine collection and the constant presence of slow multifocal epileptic discharges on the electroencephalograms. The patient's protein intake was restricted, and she was treated with sodium benzoate and arginine. After 1 year of treatment, the autistic-like findings and hyperactivity were no longer apparent.

Neuronal glucose transporter (GLUT) isoform 3 deficiency in null heterozygous mice led to abnormal spatial learning and working memory but normal acquisition and retrieval during contextual conditioning, abnormal cognitive flexibility with intact gross motor ability, electroencephalographic seizures, perturbed social behavior with reduced vocalization and stereotypies at low frequency. This phenotypic expression is unique as it combines the neurobehavioral with the epileptiform characteristics of autism spectrum disorders. This clinical presentation occurred despite metabolic adaptations consisting of an increase in microvascular/glial GLUT1, neuronal GLUT8 and monocarboxylate transporter isoform 2 concentrations, with minimal to no change in brain glucose uptake but an increase in lactate uptake. Neuron-specific glucose deficiency has a negative impact on neurodevelopment interfering with functional competence. This is the first description of GLUT3 deficiency that forms a possible novel genetic mechanism for pervasive developmental disorders, such as the neuropsychiatric autism spectrum disorders, requiring further investigation in humans.

Study of the relationship between tuberous sclerosis complex and autistic disorder.

There has been increasing awareness that there are behavioral phenotypes in tuberous sclerosis complex with neuropsychiatric symptom complex such as autistic disorder and attention-deficit hyperactivity disorder (ADHD). However, the neurobiologic basis of autistic disorder in tuberous sclerosis complex is still unknown. We studied two cohorts of children followed up since 1986 until 2003, one cohort with tuberous sclerosis complex and another cohort with autistic disorder, to determine the incidence of autistic disorder in tuberous sclerosis complex and the incidence of tuberous sclerosis complex in autistic disorder respectively. We established a Tuberous Sclerosis Complex Registry in 1985 at the University of Hong Kong. In 2004, 44 index cases (the male to female ratio was 0.75:1) were registered. Three had a positive family history of tuberous sclerosis complex. Thus, the total number of tuberous sclerosis complex cases was 47. We adopted the diagnostic criteria of tuberous sclerosis complex for case ascertainment. The period prevalence rate of tuberous sclerosis complex for children and adolescents aged < 20 years is 3.5 per 10,000 (on Hong Kong island, excluding the eastern region with 125,100 aged < 20 years in 2003). Of 44 cases with tuberous sclerosis complex, 7 had autistic disorder. Thus, the incidence of autistic disorder in tuberous sclerosis complex is 16%. During the 17-year period (1986-2003), we collected a database of 753 children (668 boys and 84 girls; male to female ratio 8:1) with autistic disorder and pervasive developmental disorders. For all children with autistic disorder or pervasive developmental disorders, we routinely examined for any features of tuberous sclerosis complex by looking for neurocutaneous markers such as depigmented spots, which appear in 50% of children with tuberous sclerosis complex by the age of 2 years. For those with infantile spasm or epilepsy, the clinical features of tuberous sclerosis complex were monitored regularly during follow-up. Of these, seven had tuberous sclerosis complex. Thus, the incidence of tuberous sclerosis complex in autistic disorder is 0.9%. All of these children are mentally retarded, with moderate to severe grades in an intellectual assessment conducted by a clinical psychologist. Future studies should be directed toward looking at the various behavioral phenotypes in tuberous sclerosis complex and defining these with standardized criteria to look for any real association with the underlying genetic mutation of TSC1 or TSC2 gene or even the site of tubers in the brain.

Cochlear implantation was effective for deaf children with congenital cytomegalovirus (CMV) infection, but their cochlear implant (CI) outcomes were often impaired, depending on the types of CMV-associated psycho-neurological disorders. Evaluation of cognitive development and autistic tendency of implantees might be useful to predict their CI outcomes. To reveal the influence of CMV-associated psycho-neurological disorders on CI outcomes. This was a retrospective evaluation of 11 implantees with congenital CMV infection (CMV-CIs) and 14 implantees with autosomal recessive hearing loss (genetic-CIs). Nine of 11 CMV-CIs suffered from psycho-neurological disorders; one from attention deficit hyperactivity disorder, two from pervasive developmental disorder, and six from mental retardation. Aided hearing thresholds with CIs in the two groups did not differ, but two autistic and two mentally retarded CMV-CIs showed significantly low scores in speech discrimination tests. Language-Social (L-S) developmental quotients (DQs) evaluated by the Kyoto Scale of Psychological development were improved after the implantation in both groups, but the postoperative increase of L-S DQs was significantly smaller in the CMV-CIs than that of genetic-CIs. Interestingly, the postoperative L-S and Cognitive-Adaptive (C-A) DQs showed statistically significant correlation in all cases except for two autistic CMV-CIs whose L-S DQs were much lower than those expected from their C-A DQs.

Adult head-banging and stereotypic movement disorders.

Mendez, M F; Mirea, A

1998-09-01

Stereotypic movement disorders (SMD) such as head-banging, which are common among children with mental retardation or pervasive developmental disorders, may also occur in intellectually normal adults. We report a 27-year history of daily head-banging with self-injury in a 49-year-old man with normal cognition. The patient had no personal or family history of Tourette's syndrome, tic disorder, obsessive-compulsive disorder (OCD), or mental retardation. The frequency of his stereotypical head-banging increased with anxiety, loud noises with startle, and boredom. He reported a sense of pleasure from his head-banging, and the frequency of this behavior decreased when he was treated with the opioid antagonist naltrexone. Although not diagnostic, the self-stimulatory or pleasurable component of head-banging, body-rocking, thumb-sucking, and other SMD may help distinguish them from tics, Tourette's syndrome, OCD, and deliberate self-harming behavior. This report reviews the disorders associated with SMD and discusses the potential mechanisms for these behaviors. The treatment of SMD includes drugs that work through opioid, serotonergic, or dopaminergic systems.

Autism Spectrum Disorder: Primary Care Principles.

PubMed

Sanchack, Kristian E; Thomas, Craig A

2016-12-15

Autism spectrum disorder is characterized by difficulty with social communication and restricted, repetitive patterns of behavior, interest, or activities. The Diagnostic and Statistical Manual of Mental Disorders, 5th ed., created an umbrella diagnosis that includes several previously separate conditions: autistic disorder, Asperger syndrome, childhood disintegrative disorder, and pervasive developmental disorder not otherwise specified. There is insufficient evidence to recommend screening for autism spectrum disorder in children 18 to 30 months of age in whom the disorder is not suspected; however, there is a growing body of evidence that early intensive behavioral intervention based on applied behavior analysis improves cognitive ability, language, and adaptive skills. Therefore, early identification of autism spectrum disorder is important, and experts recommend the use of a validated screening tool at 18- and 24-month well-child visits. Medications can be used as adjunctive treatment for maladaptive behaviors and comorbid psychiatric conditions, but there is no single medical therapy that is effective for all symptoms of autism spectrum disorder. Prognosis is heavily affected by the severity of diagnosis and the presence of intellectual disability. Children with optimal outcomes receive earlier, more intensive behavioral interventions and less pharmacologic treatment.

This study examined the effectiveness of using a weighted vest for increasing attention to a fine motor task and decreasing self-stimulatory behaviors in preschool children with pervasive developmental disorders (PDD). Using an ABA single-subject design, the duration of attention to task and self-stimulatory behaviors and the number of distractions were measured in five preschool children with PDD over a period of 6 weeks. During the intervention phase, all participants displayed a decrease in the number of distractions and an increase in the duration of focused attention while wearing the weighted vest. All but 1 participant demonstrated a decrease in the duration of self-stimulatory behaviors while wearing a weighted vest; however, the type of self-stimulatory behaviors changed and became less self-abusive for this child while she wore the vest. During the intervention withdrawal phase, 3 participants experienced an increase in the duration of self-stimulatory behaviors, and all participants experienced an increase in the number of distractions and a decrease in the duration of focused attention. The increase or decrease, however, never returned to baseline levels for these behaviors. The findings suggest that for these 5 children with PDD, the use of a weighted vest resulted in an increase in attention to task and decrease in self-stimulatory behaviors. The most consistent improvement observed was the decreased number of distractions. Additional research is necessary to build consensus about the effectiveness of wearing a weighted vest to increase attention to task and decrease self-stimulatory behaviors for children with PDD.

We report on the case of an infant who was hospitalized because of failure to thrive, megaloblastic anemia, and delayed psychomotor development. He was 10 months old and had been exclusively breast-fed by his vegan mother. Investigations showed vitamin B(12) deficiency with hematocytopenia and pervasive developmental disorders as well as vitamin K and vitamin D deficiencies. The infant's mother presented the same deficiencies. Introduction of vitamin supplementation normalized the biological disorders, and the infant showed weight gain and neurological improvement. This case highlights that a vegan diet during pregnancy followed by exclusive breast-feeding can induce nutritional deficiencies in the newborn, with clinical consequences. Detecting mother and child vitamin deficiencies and preventing them is essential.

Cognitive performance and the relationship between theory of mind (TOM), weak central coherence and executive function were investigated in a cohort of young people with additional learning needs. Participants were categorized by social communication questionnaire score into groups of 10 individuals within the autistic spectrum disorder (ASD) range, 14 within the pervasive developmental disorder range and 18 with few autistic traits. The ASD group were significantly poorer than the other groups on a test of cognitive flexibility. In the ASD group only, there was a strong relationship between executive performance and TOM which remained after controlling for IQ. Our findings suggest that the relationship between cognitive traits may more reliably distinguish autism than the presence of individual deficits alone.

The Wisconsin card sorting test (WCST) is applied to various types of neurological disorders. Since WCST requires the examinee's sustained efforts, it is not readily applicable to children with developmental disorders. In order to overcome this weakness, Keio version WCST (KWCST) was developed by reducing the number of cards from 128 to 48 and presenting them in two steps separated by a short pause. During which a brief instruction was given. This study was performed to clarify the changes with age in indices of KWCST and to obtain the normative value. Three hundred thirty five normal subjects, ranging from 5 to 82 years of age were examined. A simple regression analysis showed a significant age-related changes. Subjects between the middle thirties and the middle forties showed the best score in such indices as the categories achieved, perseverative errors of Nelson, difficulties of maintaining set, numbers of response cards until the first category achieved, and total errors. Most of the scores were improved in the second step across the all age groups, which might have resulted from learning during the first step and the instruction provided before the second step. KWCST can be performed briefly, and is suitable for cases with attention deficit/hyperactivity disorder and pervasive developmental disorder.

Should the DSM V drop Asperger syndrome?

PubMed

Ghaziuddin, Mohammad

2010-09-01

The DSM IV defines Asperger syndrome (AS) as a pervasive developmental (autistic spectrum) disorder characterized by social deficits and rigid focused interests in the absence of language impairment and cognitive delay. Since its inclusion in the DSM-IV, there has been a dramatic increase in its recognition both in children and adults. However, because studies have generally failed to demonstrate a clear distinction between AS and autism, some researchers have called for its elimination from the forthcoming DSM V. This report argues for a modification of its diagnostic criteria and its continued retention in the diagnostic manual.

I have described the corresponding method for bullying, independence and interpersonal relationships of company/opposite sex, thinking disorders caused by suffering damage or victimization and withdrawal and violence in the family among the problems in and in response to Asperger syndrome in adolescent cases. Psychotherapy is used for bullying and interpersonal relationship problems. Cognitive therapy and protective correspondence are more effective in bullying than the exposure method. It seems to be more effective to teach and instruct the corresponding principle as well as supportive response because interpersonal relationships are likely to involve failures. Pharmacological therapy was valid in feelings of paranoia and violence. Since the disorder has been recently conceptualized in pervasive developmental disorder, the scope of the subject has increased whereas Asperger syndrome used to be diagnosed in compliance with its classic examples. Therefore, it needs to clarify diagnostic examples based on new concepts, accumulate subject examples and verify the corresponding method with evidence.

The association between the social and communication elements of autism, and repetitive/restrictive behaviours and activities: a review of the literature.

Research continues to try and pinpoint the etiological role of particular genes and brain structure in autistic spectrum disorder (ASD), but despite a host of biological, genetic and neuropsychological research, the symptom profile of pervasive developmental disorders (PDDs) are not yet linked to etiological theory. Debate continues around whether or not there is one single dimension that incorporates the three criteria domains of social difficulties, communication deficits and repetitive or restrictive interests and behaviours as a unitary 'ASD' concept, or whether PDD as they are currently described represent the co-occurrence of separate sub-domains of developmental difficulties. Although the three criteria need to be met for a diagnosis of PDD to be made, the association between them remains unclear. This review highlights that the majority of the literature that looks at the triad of impairments suggests the symptom structure does not match that proposed by diagnostic manuals, and that the triad may no longer fit as the best way to conceptualize ASD.

We aimed to determine whether there was a decrease in the number of children diagnosed on the autism spectrum after the implementation of the new diagnostic criteria as outlined in the Diagnostic and Statistical Manual of Mental Health Disorders Fifth Edition published in May 2013. We reviewed 1552 charts of children evaluated at the Women and Children's Hospital of Buffalo, Autism Spectrum Disorders Clinic. A comparison was made of children diagnosed with autism spectrum disorder (autism, Asperger disorder, pervasive developmental disorder-not otherwise specified) from 2010 to May 2013 using the Diagnostic and Statistical Manual of Mental Health Disorders Fourth Edition, Text Revision criteria with children diagnosed from June 2013 through June 2015 under the Diagnostic and Statistical Manual of Mental Health Disorders Fifth Edition. Using χ(2) analysis, the 2013-2015 rate of autism spectrum disorder diagnosis (39%) was significantly lower (P < 0.01) than the 2010 to May 2013 sample years rate (50%). The rate of autism spectrum disorder diagnosis was significantly lower under the recently implemented Diagnostic and Statistical Manual of Mental Health Disorders Fifth Edition criteria.

Objective Children with Pervasive Developmental Disorders (PDDs) have deficits in social interaction, delayed communication and repetitive behavior as well as impairments in adaptive functioning. Many children actually show decline in adaptive skills compared to age mates over time. Method This 24-week, three-site, controlled clinical trial randomized 124 children (4 through 13 years of age) with PDDs and serious behavior problems to medication alone (MED; N=49; risperidone 0.5 to 3.5 mg/day (if ineffective, switch to aripiprazole was permitted) or medication plus parent training (PT) (COMB; N=75). Parents of children in COMB received an average of 11.4 PT sessions. Standard scores and Age Equivalent scores on Vineland Adaptive Behavior Scales were the outcome measures of primary interest. Results Seventeen subjects did not have a post-randomization Vineland. Thus, we used a mixed model with outcome conditioned on the baseline Vineland scores. Both groups showed improvement over the 24-week trial on all Vineland domains. Compared to MED, Vineland Socialization and Adaptive Composite Standard scores showed greater improvement in the COMB group (p = 0.01 and 0.05; effect sizes = 0.35.and 0.22, respectively). On Age Equivalent scores, Socialization and Communication domains showed greater improvement in COMB versus MED (p=0.03, 0.05; effect sizes = 0.33 and 0.14 respectively). Using logistic regression, children in the COMB group were twice as likely to make at least 6 months gain (equal to the passage of time) in the Vineland Communication Age Equivalent score compared to MED (p = 0.02). After controlling for IQ, this difference was no longer significant. Conclusion Reduction of serious maladaptive behavior promotes improvement in adaptive behavior. Medication plus PT shows modest additional benefit over medication alone. PMID:22265360

Background/Aim The Questionnaire: Children with Difficulties (QCD) is a parent-assessed questionnaire designed to evaluate child’s difficulties in functioning during specific periods of the day. This study aimed to evaluate difficulties in daily functioning of children and adolescents with pervasive developmental disorder (PDD) using the QCD. Results were compared with those for a community sample. Methods A case–control design was used. The cases comprised elementary school students (182 males, 51 females) and junior high school students (100 males, 39 females) with PDD, whereas a community sample of elementary school students (568 males, 579 females) and junior high school students (180 males, 183 females) was enrolled as controls. Their behavior was assessed using the QCD, the Tokyo Autistic Behavior Scale (TABS), the ADHD-rating scale (ADHD-RS), and the Oppositional Defiant Behavior Inventory (ODBI) for elementary and junior high school students, respectively. Effects of gender and diagnosis on the QCD scores were analyzed. Correlation coefficients between QCD and TABS, ADHD-RS, and ODBI scores were analyzed. Results The QCD scores for the children with PDD were significantly lower compared with those from the community sample (P < 0.001). Significantly strong correlations were observed in more areas of the ADHD-RS and ODBI scores compared with the TABS scores. Conclusions Children with PDD experienced greater difficulties in completing basic daily activities; moreover, their QCD scores revealed stronger associations with their ADHD-RS and ODBI scores in comparison with their TABS scores. The difficulties of PDD, ADHD and OBDI symptoms combined in children makes it necessary to assess all diagnoses before any therapy for PDD is initiated in order to be able to evaluate its results properly.

Patients with pervasive developmental disorders (PDD) often have difficulty reading facial expressions and deciphering their implied meaning. We focused on semantic encoding related to face cognition to investigate event-related potentials (ERPs) to the subject's own face and familiar faces in children with and without PDD. Eight children with PDD (seven boys and one girl; aged 10.8+/-2.9 years; one left-handed) and nine age-matched typically developing children (four boys and five girls; aged 11.3+/-2.3 years; one left-handed) participated in this study. The stimuli consisted of three face images (self, familiar, and unfamiliar faces), one scrambled face image, and one object image (e.g., cup) with gray scale. We confirmed three major components: N170 and early posterior negativity (EPN) in the occipito-temporal regions (T5 and T6) and P300 in the parietal region (Pz). An enhanced N170 was observed as a face-specific response in all subjects. However, semantic encoding of each face might be unrelated to N170 because the amplitude and latency were not significantly different among the face conditions. On the other hand, an additional component after N170, EPN which was calculated in each subtracted waveform (self vs. familiar and familiar vs. unfamiliar), indicated self-awareness and familiarity with respect to face cognition in the control adults and children. Furthermore, the P300 amplitude in the control adults was significantly greater in the self-face condition than in the familiar-face condition. However, no significant differences in the EPN and P300 components were observed among the self-, familiar-, and unfamiliar-face conditions in the PDD children. The results suggest a deficit of semantic encoding of faces in children with PDD, which may be implicated in their delay in social communication.

Numerous medications have been tested on patients with pervasive developmental disorder not otherwise specified (PDD-NOS) and Asperger's disorder. Although many of these medications have been demonstrated to be useful, no clear primary treatment for PDD-NOS and Asperger's disorder has emerged. Despite the efficacy of some of the medicines, the acceptability and side effects have proven to be barriers to their use. Recent studies indicate that the traditional Japanese herbal medicine yokukansan (TJ-54) may be safe and useful in treating behavioral and psychological symptoms in dementia and some neuropsychiatric disorders. We aimed at evaluating both the efficacy and safety of TJ-54 in patients with well-defined PDD-NOS and Asperger's disorder. This was a 12-week prospective, open-label investigation of TJ-54 in 40 children, adolescents, and adults diagnosed with PDD-NOS or Asperger's disorder. Primary outcome measures included the Clinical Global Impressions-Severity of Illness Scale (CGI-S) and the Aberrant Behavior Checklist-Iritability subscale score (ABC-I). Forty subjects, ages 8-40 years (mean 22.7 ± 7.3 years) received a mean final TJ-54 dosage of 6.4 ± 1.3 g/day (range 2.5-7.5 g/day). Full-scale intelligence quotient (IQ) scores ranged from 70 to 110 (mean 88.9 ± 13.2). Thirty-six (90%) of 40 subjects showed fewer interfering symptoms of irritability, including aggression, self-injury, and tantrums, with a final CGI-S of 1 or 2 (normal, not at all ill or borderline mentally ill) and a 80% or greater improvement on the ABC-I. The mean CGI-S score at baseline was 6.8 ± 0.8 whereas scores at end point was 1.9 ± 0.1 (< 0.0001). ABC-I scores ranged from 11 to 29 (mean 17.4 ± 3.66) at baseline, whereas scores at week 12 ranged from 0 to 5 (mean 0.93 ± 0.97) (p <0.0001). TJ-54 was well tolerated. No subject exited the study due to a drug-related adverse event. These preliminary data suggest that TJ-54 may be effective and well tolerated for treatment of severe irritability, lethargy/withdrawal, stereotypic behavior, hyperactivity/noncompliance, and inappropriate speech in patients with PDD-NOS or Asperger's disorder. However, given the characteristics of this trial, the present findings should be taken cautiously, and larger-scale placebo-controlled studies are needed to elucidate the efficacy and tolerability of TJ-54 in this understudied population.

An examination of social interaction profiles based on the factors measured by the screen for social interaction.

2014-10-01

Deficits in the capacity to engage in social interactions are a core deficit associated with Autistic Disorder (AD) and Pervasive Developmental Disorder-Not Otherwise Specified (PDD-NOS). These deficits emerge at a young age, making screening for social interaction deficits and interventions targeted at improving capacity in this area important for early identification and intervention. Screening and early intervention efforts are particularly important given the poor short and long term outcomes for children with Autism Spectrum Disorders (ASDs) who experience social interaction deficits. The Screen for Social Interaction (SSI) is a well-validated screening measure that examines a child's capacity for social interaction using a developmental approach. The present study identified four underlying factors measured by the SSI, namely, Connection with Caregiver, Interaction/Imagination, Social Approach/Interest, and Agreeable Nature. The resulting factors were utilized to compare social interaction profiles across groups of children with AD, PDD-NOS, children with non-ASD developmental and/or psychiatric conditions and typically developing children. The results indicate that children with AD and those with PDD-NOS had similar social interaction profiles, but were able to be distinguished from typically developing children on every factor and were able to be distinguished from children with non-ASD psychiatric conditions on every factor except the Connection with Caregiver factor. In addition, children with non-ASD developmental and/or psychiatric conditions could be distinguished from typically developing children on the Connection with Caregiver factor and the Social Approach/Interest factor. These findings have implications for screening and intervention for children with ASDs and non-ASD psychiatric conditions. Copyright © 2014 Elsevier Ltd. All rights reserved.

Individuals with autism spectrum disorders (ASDs) often display symptoms from other diagnostic categories. Studies of clinical and psychosocial outcome in adult patients with ASDs without concomitant intellectual disability are few. The objective of this paper is to describe the clinical psychiatric presentation and important outcome measures of a large group of normal-intelligence adult patients with ASDs. Autistic symptomatology according to the DSM-IV-criteria and the Gillberg & Gillberg research criteria, patterns of comorbid psychopathology and psychosocial outcome were assessed in 122 consecutively referred adults with normal intelligence ASDs. The subjects consisted of 5 patients with autistic disorder (AD), 67 with Asperger's disorder (AS) and 50 with pervasive developmental disorder not otherwise specified (PDD NOS). This study group consists of subjects pooled from two studies with highly similar protocols, all seen on an outpatient basis by one of three clinicians. Core autistic symptoms were highly prevalent in all ASD subgroups. Though AD subjects had the most pervasive problems, restrictions in non-verbal communication were common across all three subgroups and, contrary to current DSM criteria, so were verbal communication deficits. Lifetime psychiatric axis I comorbidity was very common, most notably mood and anxiety disorders, but also ADHD and psychotic disorders. The frequency of these diagnoses did not differ between the ASD subgroups or between males and females. Antisocial personality disorder and substance abuse were more common in the PDD NOS group. Of all subjects, few led an independent life and very few had ever had a long-term relationship. Female subjects more often reported having been bullied at school than male subjects. ASDs are clinical syndromes characterized by impaired social interaction and non-verbal communication in adulthood as well as in childhood. They also carry a high risk for co-existing mental health problems from a broad spectrum of disorders and for unfavourable psychosocial life circumstances. For the next revision of DSM, our findings especially stress the importance of careful examination of the exclusion criterion for adult patients with ASDs.

Effect of a single neonatal oxytocin treatment (hormonal imprinting) on the biogenic amine level of the adult rat brain: could oxytocin-induced labor cause pervasive developmental diseases?

Perinatal single-hormone treatment causes hormonal imprinting with lifelong consequences in receptor-binding capacity, hormone production as well as in social and sexual behavior. In the present experiments, newborn rats were treated with a single dose of oxytocin, and the levels of biogenic amines and their metabolites were studied in 8 different brain regions and in the sera when the male and female animals were 4 months old. Both dopaminergic and serotonergic neurotransmission was found to be significantly influenced. The levels of 3,4-dihydroxyphenylacetic acid, homovanillic acid, and 5-hydroxyindole acetic acid metabolites decreased in the hypothalamus and striatum. Dopamine, serotonin, norepinephrine, and 5-hydroxytryptophol levels were hardly altered, and there was no difference in the epinephrine levels. The results show that dopamine and serotonin metabolism of hypothalamus and striatum are deeply and lifelong influenced by a single neonatal oxytocin treatment Oxytocin imprinting resulted in decreased dopamine turnover in the hypothalamus and decreased serotonin turnover in the hypothalamus, medulla oblongata, and striatum of females. As the disturbance of brain dopamine and serotonin system has an important role in the development of pervasive developmental diseases (eg, autism) and neuropsychiatric disorders (eg, schizophrenia), the growing number of oxytocin-induced labor as a causal factor, cannot be omitted.

To contribute to the dearth of literature on the prevalence rates of psychiatric disorders in deaf adults, this study examined the diagnostic and clinical characteristics of deaf psychiatric outpatients in comparison to hearing psychiatric outpatients. Archival clinical data for deaf adults (N=241), treated at a specialized, linguistically and culturally affirmative outpatient community mental health program from 2002 to 2010, was compared to data from a random sample of hearing adult outpatients (N=345) who were treated at the same community mental health center. In various diagnostic categories, significant differences were seen between the deaf and hearing groups: bipolar disorders (3.7% versus 14.2%), impulse control disorders (15.8% versus 5.2%), anxiety disorders (18.7% versus 30.1%), attention deficit hyperactivity disorder (11.2% versus 4.9%), pervasive developmental disorders (3.3% versus 0.3%), substance use disorders (27.8% versus 48.4%), and intellectual disabilities (10.4% versus 2.9%). The deaf outpatient group evidenced a different diagnostic profile than the hearing sample. It is suggested that the use of culturally competent and fluent ASL-signing clinicians provides more diagnostic clarity and is encouraged as a best practice for the care of deaf individuals.

Eighteen children (13 males, five females) who had severe developmental language delay/disorder and some features of autism (although insufficient in severity and combination to meet ICD-10 diagnostic criteria for childhood autism) at preschool age (Time 1; mean age 4 years 4 months) were followed up 4 years later (Time 2; mean age 8 years 7 months). At the initial assessment the diagnostic dilemma was how much the social communication impairments and behavioural problems were secondary to the language problem and how much they constituted a genuine case of a pervasive developmental disorder. It was anticipated that at follow-up some children would continue to show social impairments but that in others social impairments would have receded as language competence improved. Follow-up assessments included the Wechsler Intelligence Scale for Children, the Clinical Evaluation of Language Fundamentals, the Children's Communication Checklist, and the Social Communication Questionnaire. At follow-up, five children had continuing language disorder and were considered to fulfil diagnostic criteria for childhood autism, four children had continuing language disorder and met criteria for atypical autism, and nine met criteria for atypical autism but had somewhat recovered language skills. Thus, even in the subgroup of children whose language ability had improved the features of autism had not dissipated. Severity of social communication impairments and repetitive behaviours at Time 1, rated retrospectively from case notes, were associated with severity of autism symptoms and pragmatic competence at Time 2. The findings are discussed in relation to the unclear boundary between autism spectrum disorders and language delay/disorder.

The aim of this study was to determine the role that birth order, sibship size and family structure have as risk factors in the development of common childhood mental disorders. A case-control study design was conducted (N = 16,823). The group under study consisted of all those subjects who had consulted with a psychiatrist/psychologist and had received a clinical diagnosis at public mental health centres within the Region of Madrid (Spain), between 1980 and 2008. A multiple logistic regression was used to explore the independent association with each diagnosis: emotional disorders (ED) with onset specific to childhood, attention deficit hyperactivity disorder (ADHD), conduct disorder (CD), mental retardation (MR), and pervasive developmental disorder (PDD). Birth order and family structure significantly predicted the risk of being diagnosed with ED or ADHD. In addition, sibship size and sex predicted the risk of being diagnosed with a childhood mental disorder. We concluded that being the middle child and living with both biological parents appear to be protective factors against the development of ED or ADHD. Living in large families appears to increase the risk of receiving a CD, MR, or PDD diagnosis. Further research is warranted.

Why is joint attention a pivotal skill in autism?

Charman, Tony

Joint attention abilities play a crucial role in the development of autism. Impairments in joint attention are among the earliest signs of the disorder and joint attention skills relate to outcome, both in the 'natural course' of autism and through being targeted in early intervention programmes. In the current study, concurrent and longitudinal associations between joint attention and other social communication abilities measured in a sample of infants with autism and related pervasive developmental disorders at age 20 months, and language and symptom severity at age 42 months, were examined. Extending the findings from previous studies, joint attention ability was positively associated with language gains and (lower) social and communication symptoms, and imitation ability was also positively associated with later language. Some specificity in the association between different aspects of joint attention behaviours and outcome was found: declarative, triadic gaze switching predicted language and symptom severity but imperative, dyadic eye contact behaviours did not. Further, although joint attention was associated with later social and language symptoms it was unrelated to repetitive and stereotyped symptoms, suggesting the latter may have a separate developmental trajectory. Possible deficits in psychological and neurological processes that might underlie the impaired development of joint attention in autism are discussed. PMID:12639329

Adults with autism spectrum disorder as behavior technicians for young children with autism: Outcomes of a behavioral skills training program.

2015-01-01

Adults with autism spectrum disorder (ASD), who were interested in working as behavior technicians for young children with autism, participated in 2 experiments. Participants included 5 adults with Asperger syndrome or pervasive developmental disorder not otherwise specified, 19 to 23 years old, and 11 children with autism, 3 to 7 years old. In Experiment 1, training of the adults focused on the implementation of mand training via incidental teaching. Experiment 2 focused on teaching participants to use discrete-trial training (DTT) with children who exhibited problem behavior. Both experiments showed that behavioral skills training was effective for teaching the adult participants the behavioral procedures needed to teach children with autism. In addition, the children acquired skills as a result of training. Results of Experiment 2 further demonstrated that the DTT skills generalized across untrained targets and children. Social validity ratings suggested that some participants' teaching was indistinguishable from that of individuals without ASD. © Society for the Experimental Analysis of Behavior.

Neurodevelopmental disorders: cluster 2 of the proposed meta-structure for DSM-V and ICD-11.

Andrews, G; Pine, D S; Hobbs, M J; Anderson, T M; Sunderland, M

2009-12-01

DSM-IV and ICD-10 are atheoretical and largely descriptive. Although this achieves good reliability, the validity of diagnoses can be increased by an understanding of risk factors and other clinical features. In an effort to group mental disorders on this basis, five clusters have been proposed. We now consider the second cluster, namely neurodevelopmental disorders. We reviewed the literature in relation to 11 validating criteria proposed by a DSM-V Task Force Study Group. This cluster reflects disorders of neurodevelopment rather than a 'childhood' disorders cluster. It comprises disorders subcategorized in DSM-IV and ICD-10 as Mental Retardation; Learning, Motor, and Communication Disorders; and Pervasive Developmental Disorders. Although these disorders seem to be heterogeneous, they share similarities on some risk and clinical factors. There is evidence of a neurodevelopmental genetic phenotype, the disorders have an early emerging and continuing course, and all have salient cognitive symptoms. Within-cluster co-morbidity also supports grouping these disorders together. Other childhood disorders currently listed in DSM-IV share similarities with the Externalizing and Emotional clusters. These include Conduct Disorder, Attention Deficit Hyperactivity Disorder and Separation Anxiety Disorder. The Tic, Eating/Feeding and Elimination disorders, and Selective Mutisms were allocated to the 'Not Yet Assigned' group. Neurodevelopmental disorders meet some of the salient criteria proposed by the American Psychiatric Association (APA) to suggest a classification cluster.

Characteristics of REM Sleep Behavior Disorder in Childhood

2012-01-01

Study Objective: To describe our experience regarding the clinical and polysomnographic features of REM sleep behavior disorder (RBD) in childhood. Methods: This was a retrospective chart review of children and adolescents with RBD and REM sleep without atonia. Demographics, and clinical and polysomnographic information were tabulated. Our findings were compared with those in the existing literature. Results: The 15 subjects identified (13 RBD and 2 having REM sleep without atonia) had a mean age at diagnosis of 9.5 years (range 3-17 years); 11/15 (73%) were male. Nightmares were reported in 13/15 and excessive daytime sleepiness in 6/15. Two children had caused bodily harm to bedmate siblings. Comorbidities, which were multiple in some subjects, included anxiety (8/15), attention deficit disorder (10/15), nonspecific developmental delay (6/15), Smith-Magenis syndrome (1/15), pervasive developmental disorder (1/15), narcolepsy (1/15), idiopathic hypersomnia (1/15), and Moebius Syndrome (1/15). Abnormal MRI scans were seen in 5/8 evaluated subjects. Treatments consisted of clonazepam (10/15), melatonin (2/15), and discontinuation of a tricyclic agent (1/15), with a favorable response in 11 of 13. Two of 15 patients with REM sleep without atonia did not require pharmacotherapy. Conclusions: RBD in children may be associated with neurodevelopmental disabilities, narcolepsy, or medication use. It seems to be modestly responsive to benzodiazepines or melatonin. The etiology is distinct from that of common childhood arousal parasomnias and RBD in adults; congenital and neurodevelopmental disorders, medication effect, and narcolepsy coexisted in some, but none had an extrapyramidal neurodegenerative disorder.

To conduct a randomized, controlled trial to evaluate the efficacy of the Early Start Denver Model (ESDM), a comprehensive developmental behavioral intervention, for improving outcomes of toddlers diagnosed with autism spectrum disorder (ASD). Forty-eight children diagnosed with ASD between 18 and 30 months of age were randomly assigned to 1 of 2 groups: (1) ESDM intervention, which is based on developmental and applied behavioral analytic principles and delivered by trained therapists and parents for 2 years; or (2) referral to community providers for intervention commonly available in the community. Compared with children who received community-intervention, children who received ESDM showed significant improvements in IQ, adaptive behavior, and autism diagnosis. Two years after entering intervention, the ESDM group on average improved 17.6 standard score points (1 SD: 15 points) compared with 7.0 points in the comparison group relative to baseline scores. The ESDM group maintained its rate of growth in adaptive behavior compared with a normative sample of typically developing children. In contrast, over the 2-year span, the comparison group showed greater delays in adaptive behavior. Children who received ESDM also were more likely to experience a change in diagnosis from autism to pervasive developmental disorder, not otherwise specified, than the comparison group. This is the first randomized, controlled trial to demonstrate the efficacy of a comprehensive developmental behavioral intervention for toddlers with ASD for improving cognitive and adaptive behavior and reducing severity of ASD diagnosis. Results of this study underscore the importance of early detection of and intervention in autism.

Anxiety in Children and Adolescents with Autism Spectrum Disorders

2009-01-01

Anxiety and poor stress management are common concerns in clinical samples of children with autism spectrum disorders (ASD). Anxiety may worsen during adolescence, as young people face an increasingly complex social milieu and often become more aware of their differences and interpersonal difficulties. This review summarizes the state of research on the prevalence, phenomenology, and treatment of anxiety in youth with autism and related conditions such as Asperger’s disorder. Using search words autism, asperger(s), or pervasive developmental disorder and anxiety or anxious to find reports published between 1990 and 2008, this review identified 40 papers. The results of the review suggest that anxiety, whether measured categorically or dimensionally, is indeed common in children and adolescents with autism spectrum disorders and may be a source of additional morbidity. The assessment of anxiety disorders in ASD should be conducted using multiple informants and modalities, as children with ASD often do not display age-typical symptoms of anxiety. To date, relatively few controlled intervention studies using well-characterized samples have been conducted despite preliminary evidence for efficacy of select pharmacological and psychosocial approaches. Recommendations for future applied research are presented and clinical implications are explored. PMID:19223098

Autism spectrum disorders (ASDs) also known as pervasive developmental disorders (PDD) are a behaviorally defined group of neurodevelopmental disorders that are usually diagnosed in early childhood. ASDs disproportionately affect male children. Mercury (Hg) a heavy metal, is widespread and persistent in the environment. Mercury is a ubiquitous source of danger in fish, drugs, fungicides/herbicides, dental fillings, thermometers, and many other products. Elevated Hg concentrations may remain in the brain from several years to decades following exposure. This is important because investigators have long recognized that Hg is a neurodevelopmental poison; it can cause problems in neuronal cell migration and division, and can ultimately cause cell degeneration and death. Case-reports of patients have described developmental regressions with ASD symptoms following fetal and/or early childhood Hg exposure, and epidemiological studies have linked exposure to Hg with an elevated risk of a patient being diagnosed with an ASD. Immune, sensory, neurological, motor, and behavioral dysfunctions similar to traits defining or associated with ASDs were reported following Hg intoxication with similarities extending to neuroanatomy, neurotransmitters, and biochemistry. The sexual dimorphism of ASDs may result from synergistic neurotoxicity caused by the interaction of testosterone and Hg; in contrast, estrogen is protective, mitigating the toxicity of Hg. Mercury exposure may significantly increase androgen levels, and as a result, patients diagnosed with an ASD may significantly benefit from anti-androgen therapy. Finally, the clinical geneticist has a wealth of biomarkers to evaluate and treat patients diagnosed with an ASD.

Yokukansan (TJ-54) for treatment of pervasive developmental disorder not otherwise specified and Asperger’s disorder: a 12-week prospective, open-label study

PubMed Central

2012-01-01

Background Numerous medications have been tested on patients with pervasive developmental disorder not otherwise specified (PDD-NOS) and Asperger’s disorder. Although many of these medications have been demonstrated to be useful, no clear primary treatment for PDD-NOS and Asperger’s disorder has emerged. Despite the efficacy of some of the medicines, the acceptability and side effects have proven to be barriers to their use. Recent studies indicate that the traditional Japanese herbal medicine yokukansan (TJ-54) may be safe and useful in treating behavioral and psychological symptoms in dementia and some neuropsychiatric disorders. We aimed at evaluating both the efficacy and safety of TJ-54 in patients with well-defined PDD-NOS and Asperger’s disorder. Methods This was a 12-week prospective, open-label investigation of TJ-54 in 40 children, adolescents, and adults diagnosed with PDD-NOS or Asperger’s disorder. Primary outcome measures included the Clinical Global Impressions-Severity of Illness Scale (CGI-S) and the Aberrant Behavior Checklist-Iritability subscale score (ABC-I). Results Forty subjects, ages 8–40 years (mean 22.7 ± 7.3 years) received a mean final TJ-54 dosage of 6.4 ± 1.3 g/day (range 2.5-7.5 g/day). Full-scale intelligence quotient (IQ) scores ranged from 70 to 110 (mean 88.9 ± 13.2). Thirty-six (90%) of 40 subjects showed fewer interfering symptoms of irritability, including aggression, self-injury, and tantrums, with a final CGI-S of 1 or 2 (normal, not at all ill or borderline mentally ill) and a 80% or greater improvement on the ABC-I. The mean CGI-S score at baseline was 6.8 ± 0.8 whereas scores at end point was 1.9 ± 0.1 (< 0.0001). ABC-I scores ranged from 11 to 29 (mean 17.4 ± 3.66) at baseline, whereas scores at week 12 ranged from 0 to 5 (mean 0.93 ± 0.97) (p <0.0001). TJ-54 was well tolerated. No subject exited the study due to a drug-related adverse event. Conclusions These preliminary data suggest that TJ-54 may be effective and well tolerated for treatment of severe irritability, lethargy/withdrawal, stereotypic behavior, hyperactivity/noncompliance, and inappropriate speech in patients with PDD-NOS or Asperger’s disorder. However, given the characteristics of this trial, the present findings should be taken cautiously, and larger-scale placebo-controlled studies are needed to elucidate the efficacy and tolerability of TJ-54 in this understudied population.

Aim of this study was to compare children diagnosed with Pervasive Developmental Disorder (PDD) according to DSM-IV-TR and DSM-5 diagnostic systems. One hundred fifty children aged between 3 and 15 years diagnosed with PDD by DSM-IV-TR were included. PDD symptoms were reviewed through psychiatric assessment based on DSM-IV-TR and DSM-5 criteria. Clinical severity was determined using Childhood Autism Rating Scale (CARS) and Autism Behavior Checklist (ABC). A statistically significant decrease (19.3 %) was detected in the diagnostic ratio with DSM-5. Age and symptom severity differed significantly between those who were and were not diagnosed with PDD using DSM-5. B4 criteria in DSM-5 was most common criterion. Results indicate that individuals diagnosed with PDD by DSM-IV-TR criteria may not be diagnosed using DSM-5 criteria.

Asperger's syndrome and autism: comparison of early history and outcome.

The authors compared children with Asperger syndrome (AS) with high-functioning autistic children and psychiatric outpatient controls on measures of early history and outcome. In terms of their early history, the autistic probands showed more social impairment, a higher frequency of echolalia and pronoun reversal, and a more restricted range of activities than the AS group. Cluster analysis suggested refinements to the diagnostic criteria, which resulted in larger differences between the groups on these early history measures. In terms of their outcome, the autistic probands spent more time in special education classes but developed fewer accessory psychiatric symptoms than the AS children. It was clear, however, that there were no substantive, qualitative differences between the AS and autistic groups, indicating that AS should be considered a mild form of high-functioning autism. The inclusion of AS among the autistic spectrum of disorders has implications both for aetiological studies and for prevalence estimates of the pervasive developmental disorders.

Comparison of direct observational methods for measuring stereotypic behavior in children with autism spectrum disorders.

2004-01-01

We compared partial-interval recording (PIR) and momentary time sampling (MTS) estimates against continuous measures of the actual durations of stereotypic behavior in young children with autism or pervasive developmental disorder-not otherwise specified. Twenty-two videotaped samples of stereotypy were scored using a low-tech duration recording method, and relative durations (i.e., proportions of observation periods consumed by stereotypy) were calculated. Then 10, 20, and 30s MTS and 10s PIR estimates of relative durations were derived from the raw duration data. Across all samples, PIR was found to grossly overestimate the relative duration of stereotypy. Momentary time sampling both over- and under-estimated the relative duration of stereotypy, but with much smaller errors than PIR (Experiment 1). These results were replicated across 27 samples of low, moderate and high levels of stereotypy (Experiment 2).

A random walk model to evaluate autism

A common test administered during neurological examination in children is the analysis of their social communication and interaction across multiple contexts, including repetitive patterns of behavior. Poor performance may be associated with neurological conditions characterized by impairments in executive function, such as the so-called pervasive developmental disorders (PDDs), a particular condition of the autism spectrum disorders (ASDs). Inspired in these diagnosis tools, mainly those related to repetitive movements and behaviors, we studied here how the diffusion regimes of two discrete-time random walkers, mimicking the lack of social interaction and restricted interests developed for children with PDDs, are affected. Our model, which is based on the so-called elephant random walk (ERW) approach, consider that one of the random walker can learn and imitate the microscopic behavior of the other with probability f (1 - f otherwise). The diffusion regimes, measured by the Hurst exponent (H), is then obtained, whose changes may indicate a different degree of autism.

This research aims to investigate differences in speech comprehension between children with specific language impairment (SLI) and their developmentally normal peers, and the relationship between speech comprehension and emotional/behavioral problems on Achenbach's Child Behavior Checklist (CBCL) and Caregiver Teacher's Report Form (C-TRF) according to the DSMIV The clinical sample comprised 97preschool children with SLI, while the peer sample comprised 60 developmentally normal preschool children. Children with SLI had significant delays in speech comprehension and more emotional/behavioral problems than peers. In children with SLI, speech comprehension significantly correlated with scores on Attention Deficit/Hyperactivity Problems (CBCL and C-TRF), and Pervasive Developmental Problems scales (CBCL)(p<0.05). In the peer sample, speech comprehension significantly correlated with scores on Affective Problems and Attention Deficit/Hyperactivity Problems (C-TRF) scales. Regression analysis showed that 12.8% of variance in speech comprehension is saturated with 5 CBCL variables, of which Attention Deficit/Hyperactivity (beta = -0.281) and Pervasive Developmental Problems (beta = -0.280) are statistically significant (p < 0.05). In the reduced regression model Attention Deficit/Hyperactivity explains 7.3% of the variance in speech comprehension, (beta = -0.270, p < 0.01). It is possible that, to a certain degree, the same neurodevelopmental process lies in the background of problems with speech comprehension, problems with attention and hyperactivity, and pervasive developmental problems. This study confirms the importance of triage for behavioral problems and attention training in the rehabilitation of children with SLI and children with normal language development that exhibit ADHD symptoms.

2014-06-01

Heterogeneity in the presentation, antecedents, prognosis and treatment response of antisocial behaviour has long provided a challenge to developmental psychopathology researchers. As illustrated in the incisive Frick and colleagues' Annual Research Review, there is growing evidence that the presence of high callous-unemotional (CU) traits identifies a subgroup of antisocial young people with a particularly aggressive and pervasive form of disorder. Frick and colleagues extend their developmental psychopathology approach to CU traits by linking in theories of conscience development and considering evidence on the stability of CU traits. This commentary addresses these themes and the area more generally, considering (1) comparison of a CU specifier to alternative approaches to antisocial heterogeneity (2) high CU traits in the absence of antisocial behaviour and (3) aspects of the measurement of CU traits. © 2014 The Author.

The heterogeneity in financial and time burden of caregiving to children with chronic conditions.

Zan, Hua; Scharff, Robert L

2015-03-01

We examine the financial and time burdens associated with caring for children with chronic conditions, focusing on disparities across types of conditions. Using linked data from the 2003 to 2006 National Health Interview Survey and 2004-2008 Medical Expenditure Panel Survey, we created measures of financial burden (out-of-pocket healthcare costs, the ratio of out-of-pocket healthcare costs to family income, healthcare costs paid by insurance, and total healthcare costs) and time burden (missed school time due to illness or injury and the number of doctor visits) associated with 14 groups of children's chronic conditions. We used the two-part model to assess the effect of condition on financial burden and finite mixture/latent class model to analyze the time burden of caregiving. Controlling for the influences of other socio-demographic characteristics on caregiving burden, children with chronic conditions have higher financial and time burdens relative to caregiving burdens for healthy children. Levels of financial burden and burden sharing between families and insurance system also vary by type of condition. For example, children with pervasive developmental disorder or heart disease have a relatively low financial burden for families, while imposing a high cost on the insurance system. In contrast, vision difficulties are associated with a high financial burden for families relative to the costs borne by others. With respect to time burden, conditions such as cerebral palsy and heart disease impose a low time burden, while conditions such as pervasive developmental disorder are associated with a high time burden. This study demonstrates that differences exist in caregiving burden for children by type of chronic condition. Each condition has a unique profile of time and financial cost burden for families and the insurance system. These results have implications for policymakers and for families' savings and employment decisions.

2012-01-01

In this study socio-demographic, deafness-related and diagnostic characteristics of hearing impaired children and adolescents referred to a national mental health service for deaf and hard of hearing children and adolescents were examined. Socio-demographic and diagnostic characteristics were compared to corresponding characteristics of hearing referred peers with identified mental health problems. The difference in characteristics between them and hearing referred peers with identified mental health problems was analyzed. A total of 389 deaf and hard of hearing and 3361 hearing children and adolescents was extracted from a database, all first referrals of patients of a center for child and adolescent psychiatry over a 15-year period. With deaf and hard of hearing patients we found higher rates of environmental stress, as indicated by conditions such as more one parent families (38.6% versus 25.8%), and more parents with a low educational level (44.2% versus 31.1%). Moreover, deaf and hard of hearing patients were older at their first referral (10.8 versus 9.4 years) and had higher rates of pervasive developmental disorders (23.7% versus 12.3%) and mental retardation (20.3% versus 3.9%). Within the target group of deaf and hard of hearing patients, most patients were deaf (68.9%; 22.3% was severely hard of hearing), relatively few (13.7%) had a non-syndromal hereditary hearing impairment, and more (21.3%) had a disabling physical health condition, especially those with a pervasive developmental disorder (42.6%). These findings illustrate both the complexity of the problems of deaf and hard of hearing children and adolescents referred to specialist mental health services, and the need for preventive interventions aimed at early recognition.

2008-12-01

Challenging behaviours are frequently a problem for people with autism spectrum disorders (ASD) and intellectual disability (ID). A better understanding of which individuals display which behaviours, at what rates, and the relationship of these behaviours to comorbid psychopathology would have important implications. A group of 161 adults with ASD (autistic disorder or Pervasive Developmental Disorder--Not Otherwise Specified [PDD-NOS]) and 159 matched controls with ID only residing in two large residential facilities in Southeastern United States, were studied using the Autism Spectrum Disorders--Behavior Problems for Adults (ASD-BPA). In all four categories of challenging behaviour measured by the ASD-BPA (Aggression/Destruction, Stereotypy, Self-Injurious Behavior, and Disruptive Behavior), frequency of challenging behaviours increased with severity of autistic symptoms. The greatest group differences were found for Stereotypy (repeated/unusual vocalisations/body movements and unusual object play), Self-Injurious Behavior (harming self and mouthing/swallowing objects), Aggression/Destruction (banging on objects), and Disruptive Behavior (elopement). Challenging behaviours in people with ASD and ID are barriers to effective education, training, and social development, and often persist throughout adulthood. Thus, programs designed to remediate such behaviours should continue across the life-span of these individuals.

To highlight the harmfulness and pervasive of early and repeated exposure to family violence from the theoretical perspective of complex trauma as a developmental disorder. A study carried out on a sample of 22 adolescents between the ages of 15 and 18, who have been entrusted to Il Faro Bologna, a Specialist Centre for child abuse and neglect. Specific areas of psychological functioning were examined. According to the NCTSN these areas are considered vulnerable to violence in primary relationships and crucial for future mental health. They are attachment, self-concept, affect regulation, cognition and behavioural control. The data was correlated with the different forms of maltreatment and the main risk factors detected in the family environment and was collected by means of clinical interviews, family and social histories, structured interviews and self-reports recommended by the NASMHPD. The data highlights a correlation between the psychic functions examined and exposure to family violence, distortion of parental empathy and parental responsibility failure. The study indicates the need: a) to raise clinical awareness of the consequences of complex trauma on development; b) to adopt specific diagnostic tools for evaluating post-traumatic outcomes; c) to carry out regular screening in order to explore histories of maltreatment in patients cared for by mental health services.

With the purpose of obtaining this information, a screening test, the Prueba Nacional de Pesquisa (PRUNAPE) for PPD was implemented in three health centres in San Isidro, a city near Buenos Aires, attended by different socio-economic groups: centres A and B were located in the inner city, and C in a middle-class area. The test was administered by three previously trained paediatricians to 839 apparently healthy children aged 0-5 years. The failure rates were 24%, 19% and 16% in centres A, B and C respectively (20% in total). Out of the 170 children failing the test and referred to hospital for diagnosis and treatment, only 96 complied and went through a series of studies carried out by a previously prepared multidisciplinary team. With the exception of children who failed the Battelle test [classified as Global Developmental Delay (GDD)], final diagnoses were classified according to Diagnostic and Statistical Manual of Mental Disorders, 4th edition: GDD (60 children), pervasive developmental disorders (11), communication disorders (10), motor disorders (6, of whom 2 were with cerebral palsy), attention deficit disorders (5), attachment disorders (2), normal children (3). Co-morbidity was present in 22 affected children. Forty-three per cent of children failing the test did not attend hospital or did not complete studies because of major social and family problems, the family not living in the area, or the parents preferring to consult their own paediatrician. Health centres and children not selected in a randomised way, and a significant proportion of them not complying with the indication of hospital referral were major sources of bias, so that PPD prevalences, positive and negative predictive values should be interpreted with great caution. Further studies accounting for these sources of bias are needed to confirm the observed prevalence of PPD. Training of health personnel, at hospital and health centre level, priority settings, and operational research to evaluate effectiveness of treatments and care delivery systems at field level are necessary in Argentina for optimal use of limited healthcare resources.

Mental health in the United States: parental report of diagnosed autism in children aged 4-17 years--United States, 2003-2004.

PubMed

2006-05-05

Autism is a lifelong neurodevelopmental disorder characterized by early onset of impairments in social interaction and communication and unusual, stereotyped behaviors. Autism (i.e., autistic disorder) often is classified with two related, although less severe, developmental disorders: Asperger disorder and pervasive developmental disorder--not otherwise specified. These three constitute the autism spectrum disorders (ASDs). Diagnosis of ASDs is based exclusively on developmental pattern and behavioral observation. Two population-based studies conducted by CDC in selected U.S. locations reported ASD prevalence of 3.4 and 6.7 per 1,000 children, respectively. CDC also conducts two nationally representative surveys, the National Health Interview Survey (NHIS) and the National Survey of Children's Health (NSCH), in which parents are asked whether their child ever received a diagnosis of autism. Because of similarities in methodology used by the two surveys, CDC analyzed 2003-2004 data from NHIS and data from the first-ever NSCH (collected during January 2003-July 2004) to 1) estimate the population-based prevalence of parental report of diagnosed autism in the United States and 2) assess parental reporting of child social, emotional, and behavioral strengths and difficulties and special-health care needs among children with and without reported autism. This report describes the results of that analysis, which indicated that the prevalence of parent-reported diagnosis of autism was 5.7 per 1,000 children in NHIS and 5.5 per 1,000 children in NSCH. Prevalence estimates in the two studies were similar across age, sex, and racial/ethnic populations. The consistency in estimates between the two surveys suggests high reliability for parental report of autism. These estimates suggest that, as of 2003-2004, autism had been diagnosed in at least 300,000 U.S. children aged 4-17 years. In addition, parental reports of autism were associated with reported social, emotional, and behavioral symptoms and specialized needs. Thus, these surveys might be useful to assess health, education, and social service needs of children with autism.

Attention-deficit hyperactivity disorder (ADHD) is a complex developmental neuropsychiatric disorder, characterized by inattentiveness, impulsivity, and hyperactivity. Recent literature suggests a potential core deficit underlying these behaviors may involve inefficient processing when contextual stimulation is low. In order to specify this inefficiency, the aim of the present study was to disentangle perceptual and response-based deficits of attention by supplementing classic reaction time (RT) measures with an accuracy-only test. Moreover, it was explored whether ADHD symptom severity was systematically related to perceptual and response-based processes. We applied an RT-independent paradigm (Bundesen, 1990) and a sustained attention task (Dockree et al., 2006) to test visual attention in 24 recently diagnosed, medication-naïve children with ADHD, 14 clinical controls with pervasive developmental disorder, and 57 healthy controls. Outcome measures included perceptual processing speed, capacity of visual short-term memory, and errors of commission and omission. Children with ADHD processed information abnormally slow (d = 0.92), and performed poorly on RT variability and response stability (d's ranging from 0.60 to 1.08). In the ADHD group only, slowed visual processing speed was significantly related to response lapses (omission errors). This correlation was not explained by behavioral ratings of ADHD severity. Based on combined assessment of perceptual and response-dependent variables of attention, the present study demonstrates a specific cognitive profile in children with ADHD. This profile distinguishes the disorder at a basic level of attentional functioning, and may define subgroups of children with ADHD in a way that is more sensitive than clinical rating scales.

Recent neuroimaging studies suggest that autism spectrum disorder results from abnormalities in the cortical folding pattern. Usual morphometric measurements have failed to provide reliable neuroanatomic markers. Here, we propose that sulcal pits, which are the deepest points in each fold, are suitable candidates to uncover this atypical cortical folding. Sulcal pits were extracted from a magnetic resonance imaging database of 102 children (1.5-10 years old) distributed in three groups: children with autistic disorder (n = 59), typically developing children (n = 22), and children with pervasive developmental disorder not otherwise specified (n = 21). The geometrical properties of sulcal pits were compared between these three groups. Fold-level analyses revealed a reduced pit depth in the left ascending ramus of the Sylvian fissure in children with autistic disorder only. The depth of this central fold of Broca's area was correlated with the social communication impairments that are characteristic of the pathology. Our findings support an atypical gyrogenesis of this specific fold in autistic disorder that could be used for differential diagnosis. Sulcal pits constitute valuable markers of the cortical folding dynamics and could help for the early detection of atypical brain maturation. Copyright © 2016 Society of Biological Psychiatry.

Autism Spectrum Disorder: Classification, diagnosis and therapy.

Sharma, Samata R; Gonda, Xenia; Tarazi, Frank I

Autism Spectrum Disorder (ASD) refers to a group of neurodevelopmental disorders including autism, Asperger's syndrome (AS) and pervasive developmental disorder-not otherwise specified (PDD-NOS). The new diagnostic criteria of ASD focuses on two core domains: social communication impairment and restricted interests/repetitive behaviors. The prevalence of ASD has been steadily increasing over the past two decades, with current estimates reaching up to 1 in 36 children. Hereditary factors, parental history of psychiatric disorders, pre-term births, and fetal exposure to psychotropic drugs or insecticides have all been linked to higher risk of ASD. Several scales such as the Childhood Autism Rating Scale (CARS), The Autism Spectrum Disorder-Observation for Children (ASD-OC), The Developmental, Dimensional, and Diagnostic Interview (3di), are available to aid in better assessing the behaviors and symptoms associated with ASD. Nearly 75% of ASD patients suffer from comorbid psychiatric illnesses or conditions, which may include attention-deficit hyperactivity disorder (ADHD), anxiety, bipolar disorder, depression, Tourette syndrome, and others. Both pharmacological and non-pharmacological interventions are available for ASD. Pharmacological treatments include psychostimulants, atypical antipsychotics, antidepressants, and alpha-2 adrenergic receptor agonists. These medications provide partial symptomatic relief of core symptoms of ASD or manage the symptoms of comorbid conditions. Non-pharmacological interventions, which show promising evidence in improving social interaction and verbal communication of ASD patients, include music therapy, cognitive behavioral therapy and social behavioral therapy. Hormonal therapies with oxytocyin or vasopressin receptor antagonists have also shown some promise in improving core ASD symptoms. The use of vitamins, herbal remedies and nutritional supplements in conjunction with pharmacological and behavioral treatment appear to have some effect in symptomatic improvement in ASD, though additional studies are needed to confirm these benefits. Developing novel disease-modifying therapies may prove to be the ultimate intervention for sustained improvement of symptoms in ASD. Copyright © 2018 Elsevier Inc. All rights reserved.

[Psychomotor re-education--movement as therapeutic method].

PubMed

Golubović, Spela; Tubić, Tatjana; Marković, Slavica

2011-01-01

Psychomotor re-education represents a multidimensional therapeutic approach in dealing with children and adults with psychomotor disorders. Therapeutic programs should be based on individual differences, abilities and capabilities, relationships, feelings and individual developmental needs as well as emotional condition of a child. BODY AND MOVEMENT AS THE Bases OF THE TREATMENT: A movement, glance, touch, voice and word, all being an integral part of a process of psychomotor re-education, are used with a purpose of helping children to discover their own body, their feelings, needs, behaviour. When moving, children discover the space of their own bodily nature, and, subsequently, gestural space and objective space. The body represents a source of pleasure and the freedom of movement, as well as one's own existence, are soon to be discovered. An adequate assessment is a precondition to design a work plan, select the best exercises for each child individually and direct the course of therapy. This is the most suitable method for treating children with slow or disharmonious development, mentally challenged children, children with speech and behaviour disorders. It is also used in the treatment of children with dyspraxic difficulties, difficulties in practognostic and gnostic development, pervasive developmental disorder and children with lateral dominance problems. Therefore, a systematic observation seems to be necessary as well as an increased number of research projects aimed at assessing results obtained by exercises in order to get a more precise insight into the process of re-education, selection of exercises, duration period and possible outcomes.

The Many Faces of Dissociation: Opportunities for Innovative Research in Psychiatry

PubMed Central

2014-01-01

It has been claimed that the progress of psychiatry has lagged behind that of other medical disciplines over the last few decades. This may suggest the need for innovative thinking and research in psychiatry, which should consider neglected areas as topics of interest in light of the potential progress which might be made in this regard. This review is concerned with one such field of psychiatry: dissociation and dissociative disorders. Dissociation is the ultimate form of human response to chronic developmental stress, because patients with dissociative disorders report the highest frequency of childhood abuse and/or neglect among all psychiatric disorders. The cardinal feature of dissociation is a disruption in one or more mental functions. Dissociative amnesia, depersonalization, derealization, identity confusion, and identity alterations are core phenomena of dissociative psychopathology which constitute a single dimension characterized by a spectrum of severity. While dissociative identity disorder (DID) is the most pervasive condition of all dissociative disorders, partial representations of this spectrum may be diagnosed as dissociative amnesia (with or without fugue), depersonalization disorder, and other specified dissociative disorders such as subthreshold DID, dissociative trance disorder, acute dissociative disorders, and identity disturbances due to exposure to oppression. In addition to constituting disorders in their own right, dissociation may accompany almost every psychiatric disorder and operate as a confounding factor in general psychiatry, including neurobiological and psycho-pharmacological research. While an anti- dissociative drug does not yet exist, appropriate psychotherapy leads to considerable improvement for many patients with dissociative disorders. PMID:25598819

The purpose of this study was to investigate the clinical characteristics of children with mental retardation (MR) of unknown etiology for early recognition and intervention. In this study, we defined children with MR of unknown etiology as those without clear etiologies for MR despite extensive evaluation and were not associated with pathological behavioral problems such as pervasive developmental disorders and attention-deficit/hyperactivity disorder. The clinical characteristics of children with MR of unknown etiology were as follows. 1) MR of unknown etiology was 48.8% of all MR. 2) MR of unknown etiology was more common in males. 3) Delayed language development was a leading factor that made the parents of children with MR of unknown etiology seek help from physicians. However, most of the children with MR of unknown etiology showed a relatively uniform delay in several areas of development. 4) Most children with MR of unknown etiology were delayed walkers. 5) Most children with MR of unknown etiology were mild cases.

'DSM-V is taking away our identity': the reaction of the online community to the proposed changes in the diagnosis of Asperger's disorder.

PubMed

Giles, David C

2014-03-01

This article considers the fate of Asperger's disorder in the light of proposals for the Diagnostic and Statistical Manual of Mental Disorders (5th ed.) to collapse Asperger's disorder along with other pervasive developmental disorders into a general spectrum of autism. It is argued that a powerful lay and scientific culture has evolved around the concept of Asperger's disorder, which has found a particularly compelling voice over the last decade in the online Asperger community, with websites such as Wrong Planet recruiting tens of thousands of members. In order to assess the impact of these proposed changes on the online Asperger community, 19 threads on the topic of Diagnostic and Statistical Manual of Mental Disorders (5th ed.) are analysed according to the arguments that community members put forward in favour of, or in opposition to, the proposals. Many members embrace the notion of the spectrum and have already coined a new identity - 'spectrumite' - to adapt to the diagnostic shift. Others, however, are suspicious of the motives behind the absorption of Asperger's disorder, and potential threats to the provision of services as well as the strong 'aspie' identity that reflects the large literature and the online public sphere around Asperger's disorder. To what extent this culture poses a challenge to the authority of the Diagnostic and Statistical Manual of Mental Disorders is uncertain at present.

Children with autism spectrum disorders (ASD) face pervasive challenges in symbolic and social play development. The Integrated Play Groups (IPG) model provides intensive guidance for children with ASD to participate with typical peers in mutually engaging experiences in natural settings. This study examined the effects of a 12-week IPG intervention on the symbolic and social play of 48 children with ASD using a repeated measures design. The findings revealed significant gains in symbolic and social play that generalized to unsupported play with unfamiliar peers. Consistent with prior studies, the outcomes provide robust and compelling evidence that further validate the efficacy of the IPG model. Theoretical and practical implications for maximizing children's developmental potential and social inclusion in play are discussed.

2006-09-01

Parents of children with pervasive developmental disorders (n = 494) were surveyed to determine their level of satisfaction with the process of getting an autism spectrum diagnosis. Participants in this web-based study (mean age = 37.8 years) came from five countries and reported on children with an average age of 8.3 years (range = 1.7 to 22.1). All children had a diagnosis of either autism (59.9%), Asperger syndrome (23.5%), or PDD-NOS (16.6%). Higher levels of parental education and income were associated with earlier diagnosis and greater satisfaction with the diagnostic process. Parents were more satisfied with the diagnostic process when they saw fewer professionals to get the diagnosis and when the children received the diagnoses at younger ages.

Background Organophosphate (OP) pesticides are widely used in agriculture and homes. Animal studies suggest that even moderate doses are neurodevelopmental toxicants, but there are few studies in humans. Objectives We investigated the relationship of prenatal and child OP urinary metabolite levels with children’s neurodevelopment. Methods Participating children were from a longitudinal birth cohort of primarily Latino farm-worker families in California. We measured six nonspecific dialkylphosphate (DAP) metabolites in maternal and child urine as well as metabolites specific to malathion (MDA) and chlorpyrifos (TCPy) in maternal urine. We examined their association with children’s performance at 6 (n = 396), 12 (n = 395), and 24 (n = 372) months of age on the Bayley Scales of Infant Development [Mental Development (MDI) and Psychomotor Development (PDI) Indices] and mother’s report on the Child Behavior Checklist (CBCL) (n = 356). Results Generally, pregnancy DAP levels were negatively associated with MDI, but child measures were positively associated. At 24 months of age, these associations reached statistical significance [per 10-fold increase in prenatal DAPs: β = −3.5 points; 95% confidence interval (CI), −6.6 to −0.5; child DAPs: β = 2.4 points; 95% CI, 0.5 to 4.2]. Neither prenatal nor child DAPs were associated with PDI or CBCL attention problems, but both prenatal and postnatal DAPs were associated with risk of pervasive developmental disorder [per 10-fold increase in prenatal DAPs: odds ratio (OR) = 2.3, p = 0.05; child DAPs OR = 1.7, p = 0.04]. MDA and TCPy were not associated with any outcome. Conclusions We report adverse associations of prenatal DAPs with mental development and pervasive developmental problems at 24 months of age. Results should be interpreted with caution given the observed positive relationship with postnatal DAPs. PMID:17520070

Porphyrinuria in childhood autistic disorder is not associated with urinary creatinine deficiency.

2008-08-01

Urinary metabolite measurements are often normalized to levels of the ubiquitous metabolite creatinine (CRT) to take account of variations in fluid export. Following CRT normalization, excesses of porphyrins and isoprostanes have been reported in the urines of children with neurodevelopmental disorders. It was suggested (Whiteley et al., 2006, Pediatr. Int. 2006; 48: 292-297) that urinary CRT levels may be depressed in children with autism spectrum disorders. This prompted re-evaluation of CRT levels in such children. First matinal urinary CRT levels were compared between subjects in different diagnostic categories including autistic disorder, pervasive developmental disorder not otherwise specified (PDD-NOS) and hyperactivity, before and after correction for age and gender. A larger reference group, consisting of subjects with unrelated disorders and Asperger disorder, with no reported porphyrin excess, was also compared to the group with autistic disorder, both for CRT and for porphyrin (coproporphyrin, COPRO) excess. No significant difference in CRT was observed between any of the categories analyzed, also when corrected for age and gender. In contrast, urinary COPRO levels were significantly higher in autistic disorder versus reference groups, either when expressed as absolute values (independent of CRT levels) or when normalized to CRT. These data do not support a systematic reduction in urinary CRT levels in subjects with autism spectrum disorders including autistic disorder and PDD-NOS. Urinary COPRO excess in autistic disorder was not associated with or consequent upon urinary CRT deficiency. Differences between affected and control subjects in age and sampling time, as reported by Whiteley et al., may underlie the apparent CRT reduction.

Investigating sleep in mental disorders has the potential to reveal both disorder-specific and transdiagnostic psychophysiological mechanisms. This meta-analysis aimed at determining the polysomnographic (PSG) characteristics of several mental disorders. Relevant studies were searched through standard strategies. Controlled PSG studies evaluating sleep in affective, anxiety, eating, pervasive developmental, borderline and antisocial personality disorders, ADHD, and schizophrenia were included. PSG variables of sleep continuity, depth, and architecture, as well as rapid-eye movement (REM) sleep were considered. Calculations were performed with the “Comprehensive Meta-Analysis” and “R” softwares. Using random effects modeling, for each disorder and each variable, a separate meta-analysis was conducted if at least 3 studies were available for calculation of effect sizes as standardized means (Hedges’g). Sources of variability, i.e., sex, age, and mental disorders comorbidity, were evaluated in subgroup analyses. Sleep alterations were evidenced in all disorders, with the exception of ADHD and seasonal affective disorders. Sleep continuity problems were observed in most mental disorders. Sleep depth and REM pressure alterations were associated with affective, anxiety, autism and schizophrenia disorders. Comorbidity was associated with enhanced REM sleep pressure and more inhibition of sleep depth. No sleep parameter was exclusively altered in one condition; however, no two conditions shared the same PSG profile. Sleep continuity disturbances imply a transdiagnostic imbalance in the arousal system likely representing a basic dimension of mental health. Sleep depth and REM variables might play a key role in psychiatric comorbidity processes. Constellations of sleep alterations may define distinct disorders better than alterations in one single variable. PMID:27416139

Social Communication Questionnaire scoring procedures for autism spectrum disorder and the prevalence of potential social communication disorder in ASD.

In analyzing data from the National Database for Autism Research, we utilized Mokken scaling techniques as a means of creating a more effective and efficient screening procedure for autism spectrum disorder (ASD) via the Social Communication Questionnaire (SCQ). With a sample of 1,040, approximately 80% (n = 827) of the sample were males while approximately 20% (n = 213) were females. In regard to ethnicity, approximately 68% of the sample were White/Caucasian, while 7% were African American, 16% were Hispanic, 4% were Asian, and 1% were Native American or American Indian. As the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) states that, "individuals with a well-established DSM-IV diagnosis of autistic disorder, Asperger's disorder, or pervasive developmental disorder not otherwise specified should be given the diagnosis of autism spectrum disorder," (American Psychiatric Association, 2013, p. 51), the primary labeling difference between the DSM-IV and the DSM-5 would appear to be in identifying social communication disorder as a newly introduced disorder in the DSM-5, which we discuss. Though school psychologists are not dependent on the DSM to the same extent as clinical psychologists to provide services, school psychology is invested in the effective and efficient assessment of ASD. The current study demonstrates how Mokken scaling procedures may be utilized with respect to ASD identification via the SCQ as well as providing information regarding the prevalence of potential social communication disorder as a new disorder and its discrimination with ASD.

Can i have a second child? dilemmas of mothers of children with pervasive developmental disorder: a qualitative study

PubMed Central

2010-01-01

Background Pervasive developmental disorder (PDD) has an uncertain etiology, no method of treatment, and results in communication deficiencies and other behavioral problems. As the reported recurrence risk is 5%-10% and there are no methods of either prevention or prenatal testing, mothers of PDD children may face unique challenges when contemplating second pregnancies. The purpose of this study was to explore the mothers' lived experiences of second child-related decision-making after the birth of a child with PDD. Methods The participants for this study were restricted to mothers living within the greater Tokyo metropolitan area who had given birth to a first child with PDD within the past 18 years. The ten participants were encouraged to describe their experiences of second-child related decision-making after the birth of a child with PDD on the basis of semi-structured interviews. Data analysis was performed by using Interpretive Phenomenological Analysis (IPA), which is concerned with understanding what the participant thinks or believes about the topic under discussion. Results We identified two superordinate themes. The first was balancing hopes and fears, in which hope was the potential joy to be gained by the birth of a new child without PDD and fears were characterized as uncertainty of PDD and perception of recurrence risk, burden on later-born children, and negative effects on a child with PDD. The second superordinate theme was assessing the manageability of the situation, which was affected by factors as diverse as severity of PDD, relationship between mother and father, and social support and acceptance for PDD. Our 10 participants suffered from extreme psychological conflict, and lack of social support and acceptance for PDD created numerous practical difficulties in having second children. Conclusions Our participants faced various difficulties when considering second pregnancies after the birth of children with PDD in the Japanese society. As lack of social support and acceptance for PDD also played a large role in second child-related decision-making, creating a social environment that more fully accepts those disabled and providing flexible support systems for families of children with PDD are crucial.

It was examined how juvenile psychiatric disorders and adult schizotypal symptoms are associated. 731 patients of the Department of Child and Adolescent Psychiatry of the University Medical Centre Utrecht, the Netherlands, with mean age of 12.1 years (SD = 4.0) were reassessed at the mean age of 27.9 years (SD = 5.7) for adult schizotypal symptoms using the Schizotypal Personality Questionnaire-Revised (Vollema, Schizophr Bull 26(3):565-575, 2000). Differences between 13 juvenile DSM categories and normal controls (n = 80) on adult schizotypal total and factor scores were analyzed, using (M)ANCOVA. Pervasive developmental disorders (PDD), attention deficit hyperactivity disorders (ADHD), deferred diagnosis, sexual and gender identity disorders and depressive disorders had higher SPQ total scores when compared to normal controls (p < 0.001). Higher levels of disorganized schizotypal symptoms were found for PDD, ADHD, and deferred diagnosis (p < 0.001). The same diagnostic groups showed higher level of negative schizotypal symptoms, which was likewise true for sexual and gender identity disorders, depressive disorders, disruptive disorders, and the category of 'Other conditions that may be a focus of clinical attention' (p < 0.001). No differences with normal controls were found for adult positive schizotypal symptoms (p < 0.110). The current findings are suggestive of the idea that psychiatric disorders in childhood or adolescence are a more general expression of a liability to schizophrenia spectrum pathology in future life. In addition, specific patterns of adult schizotypal symptomatology are associated with different types of juvenile psychiatric disorder.

Language and emotional abilities in children with Williams syndrome and children with autism spectrum disorder: similarities and differences

Lacroix, Agnès; Famelart, Nawelle; Guidetti, Michèle

2016-01-01

Williams syndrome (WS) is a genetic disease with a relatively homogeneous profile: relatively well-preserved language, impaired cognitive activities, and hypersociability. Autism spectrum disorder (ASD) refers to a group of individuals with impairments in aspects of communication and a particular pattern of language acquisition. Although ASD and WS are polar opposites when it comes to communication abilities (language and emotion) and social behavior, comparisons between WS and ASD are still rare in the literature. ASD and WS are both associated with general language and developmental delays. Difficulties in social interaction and general pragmatic difficulties are reported in both ASD and WS, but are more pervasive in ASD. Regarding facial emotion recognition, the two syndromes differ markedly in sensitivity to human faces. Despite the heterogeneity of these two groups, only a few studies with children have paid sufficient attention to participant recruitment and study design. A number of aspects need to be taken into account (eg, small age range, homogeneity of the subgroups, matching with typically developing children) if scientific results are to inform the design of intervention programs for children with neurodevelopmental disorders such as ASD and WS.

Strahan, Brandy E; Elder, Jennifer H

2015-01-01

Adolescent obesity has tripled in the past two decades, and adolescents with disabilities, specifically autism spectrum disorders (ASD), may be at greater risk for obesity due to the behavioral, physical, and psychosocial complications related to their disorder. This case study reports the effects of video game playing on an obese adolescent with ASD and illustrates the use of a multiple baseline single subject design. Over 12 weeks, the participant played inactive (6 weeks) and active video games (6 weeks) on the Wii console. Physiological data were evaluated weekly at home. Stress and anxiety were measured via the Stress Survey Schedule for Individuals with Autism and Other Pervasive Non-Developmental Disorders (SSS) and the Behavior Assessment System for Children Second Edition (BASC-2) pre- and postintervention. The Therapy Attitude Inventory (TAI) was used to determine parental perception of video game playing as a socially valid intervention to reduce stress and anxiety. Results demonstrated that active video game playing slowed and/or reduced weight and BMI with minimal changes to waist-to-hip ratios, triceps skinfolds, and stress and anxiety. This study demonstrates how alternative methods for physical activity may be used to improve health outcomes of overweight/obese adolescents with ASD and suggests directions for future research.

In a geographical area of Stockholm, with a relatively large Somali immigrant population, parents as well as teachers in special schools and staff at habilitation centres have raised concerns over whether children with a Somali background are over-represented in the total group of children with autism. The aim of the study was, therefore, to investigate the prevalence of autism in children with parents from Somalia, living in Stockholm county, and to compare the prevalence in children of Somali background with that in the non-Somali group. We reviewed the records of 17 children (13 males, four females), born between 1988 and 1998 (age range 7-17y) and with a Somali background, who had a diagnosis of autistic disorder or pervasive developmental disorder not otherwise specified (PDDNOS) and were registered at either of the two autism habilitation centres for school-aged children. The prevalence of autistic disorder or PDDNOS was found to be three to four times higher than in the non-Somali group (0.7% vs 0.19%). All children also had learning disability.* Our findings warrant further investigations of possible aetiological factors behind the increased prevalence of autistic disorders in children of Somali origin found in this area in Sweden.

Second-generation Holocaust survivors: Psychological, theological, and moral challenges.

PubMed

Juni, Samuel

2016-01-01

Drawing from trauma theory, psychodynamic conceptualization, developmental psychology, clinical data, and personal experience, this article portrays a life haunted by tragedy predating its victims. Healthy child development is outlined, with particular attention to socialization and theological perspectives. Key characteristics of trauma are delineated, highlighting the nuances of trauma that are most harmful. As is the case with general trauma, Holocaust survivors are described as evincing survivor's guilt and paranoia in response to their experiences. Divergent disorders resulting from the Holocaust are described for 1st-generation and 2nd-generation survivors, respectively. Primary trauma responses and pervasive attitudes of survivors are shown to have harmful ramifications on their children's personality and worldview as well as on their interpersonal and theistic object relations. These limitations translate into problems in the adult lives of second generation survivors.

Pharmacologic treatment of autism.

Autism is a chronic and lifelong pervasive developmental disorder for which there is yet no effective cure, and medical management remains a major challenge for clinicians. In spite of the possible similarities with conditions that have an established pharmacotherapy, and despite improvements in some associated "problematic behaviors" following the use of available medications, effective medical treatment for the core symptoms involving language and social cognition remains elusive. The purpose of the present article is to review current biologic knowledge about autism in an attempt to correlate clinical trials with known mechanisms of disease. In addition, the need for controlled studies and for the creation of homogeneous subgroups of patients based on clinical and genetic characteristics is emphasized. The application of molecular genetic investigations and pharmacogenetics in the diagnostic work-up of autistic patients can lead to more effective individualized medical care.

Autism is a pervasive developmental disorder that affects a growing number of children in the United States each year. It is characterized by substantive differences in brain structure and function that lead to long-term cognitive and social deficits. These differences, combined with the increasing prevalence of autism in children, warrant the need for development of innovative, cost-effective and widely available alternative and complementary therapies. Motion gaming has the potential to be highly efficacious as a therapeutic technique to aid in developing memory, facial recognition, motor skills and social integration in the pediatric autistic population. This paper outlines the major deficits in the brains of individuals with autism and describes how the use of motion gaming could capitalize on the individual strengths of each patient, leading to improvements in a variety of deficits.

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.

People with autism spectrum disorder (ASD) typically have deficits in the working memory (WM) system. WM is found to be an essential chain in successfully navigating in the social world. We hypothesize that brain networks for WM have an altered network integrity in ASD compared to controls. Thirteen adolescents (one female) with autistic disorder (n = 1), Asperger's disorder (n = 7), or pervasive developmental disorder not otherwise specified (n = 5), and 13 typically developing healthy control adolescents (one female) participated in this study. Functional magnetic resonance imaging (MRI) was performed using an n-back task and in resting state. The analysis of the behavioral data revealed deficits in WM performance in ASD, but only when tested to the limit. Adolescents with ASD showed lower binary global efficiency in the WM network than the healthy control group with n-back and resting-state data. This correlated with diagnostic scores for total problems, reciprocity, and language. Adolescents with higher-functioning autism have difficulty with the WM system, which is typically compensated. Functional MRI markers of brain network organization in ASD are related to characteristics of autism as represented in diagnostic scores. Therefore, functional MRI provides neuronal correlates for memory difficulties in adolescents with ASD. © 2017 The Authors.

Many studies have focused on specific motor signs in autism and Asperger's syndrome, but few has been published on the complete range of neurological soft signs (NSS) in children with pervasive developmental disorder (PDD). Scarce are the studies evaluating NSS in children suffering from PDD not otherwise specified (PDDNOS). This study compared performance of 11 autistic children (AD) and 10 children with PDDNOS, with controls matched on age, sex and cognitive performance on Krebs et al.'s NSS scale. Because of the duration of the assessments and specific difficulties encountered in managing some items, an adaptation of the scale had to be made during a pilot study with the agreement of the author. To be eligible, patients had to meet the following inclusion criteria: an age range of 6-16 years, a diagnosis of autistic disorder or PDDNOS based on the DSM IV criteria (American Psychiatric Association 1994). The autism diagnostic interview-revised (ADI-R) was used in order to confirm the diagnosis and to evaluate the association of the symptoms to the severity of the NSS. The childhood autism rating scale (CARS) was completed for the patients in order to evaluate symptoms at the time of the NSS examination. Cognitive ability was assessed with Raven's progressive matrices. Were excluded patients with: history of cerebral palsy, congenital anomaly of the central nervous system, epilepsy, known genetic syndrome, tuberous sclerosis, neurofibromatosis, antecedent of severe head trauma, Asperger's syndrome, obvious physical deformities or sensory deficits that would interfere with neurological assessment, deep mental retardation and recent or chronic substance use or abuse. Healthy controls shared the same exclusion criteria, with no personal history of neurological, psychiatric disorder or substance abuse, no family history of psychiatric disorder and normal or retardation in schooling. All study procedures were approved by the local Ethics Committee (Comité d'éthique, Razi Hospital), according to the declaration of Helsinki. There was no difference between patients and controls with respect to sex, age and cognitive function. All children had an IQ higher than 81. Significant differences were found between AD children and control group in the motor integration function and sensory integration function. Different NSS scores were significantly higher in the PDDNOS group than in controls: the total scores, motor coordination, motor integration function, sensory integration and abnormal movements. Lower performance in motor coordination skills was associated with higher ADI-R communication score in the AD group. No relationship was found between NSS and CARS' total sore. This study confirms the impaired neurological functioning in autistic as well as PDDNOS children. The association of motor impairment with autistic symptoms highlights the argument that motor control problems can be part of the autism spectrum disorders. The lack of relationship between NSS and intellectual aptitude in the clinical sample provides new elements for the neurodevelopment model of the autism spectrum. Copyright © 2010 L’Encéphale, Paris.

Detecting the early emergence of childhood risk for adult mental disorders may lead to interventions for reducing subsequent burden of these disorders. We set out to determine classes of children who may be at risk for later mental disorder on the basis of early patterns of development in a population cohort, and associated exposures gleaned from linked administrative records obtained within the New South Wales Child Development Study. Intergenerational records from government departments of health, education, justice and child protection were linked with the Australian Early Development Census for a state population cohort of 67,353 children approximately 5 years of age. We used binary data from 16 subdomains of the Australian Early Development Census to determine classes of children with shared patterns of Australian Early Development Census-defined vulnerability using latent class analysis. Covariates, which included demographic features (sex, socioeconomic status) and exposure to child maltreatment, parental mental illness, parental criminal offending and perinatal adversities (i.e. birth complications, smoking during pregnancy, low birth weight), were examined hierarchically within latent class analysis models. Four classes were identified, reflecting putative risk states for mental disorders: (1) disrespectful and aggressive/hyperactive behaviour, labelled 'misconduct risk' ( N = 4368; 6.5%); (2) 'pervasive risk' ( N = 2668; 4.0%); (3) 'mild generalised risk' ( N = 7822; 11.6%); and (4) 'no risk' ( N = 52,495; 77.9%). The odds of membership in putative risk groups (relative to the no risk group) were greater among children from backgrounds of child maltreatment, parental history of mental illness, parental history of criminal offending, socioeconomic disadvantage and perinatal adversities, with distinguishable patterns of association for some covariates. Patterns of early childhood developmental vulnerabilities may provide useful indicators for particular mental disorder outcomes in later life, although their predictive utility in this respect remains to be established in longitudinal follow-up of the cohort.

Avoidant/Restrictive Food Intake Disorder (ARFID) is a "new" diagnosis in the recently published DSM-5, but there is very little literature on patients with ARFID. Our objectives were to determine the prevalence of ARFID in children and adolescents undergoing day treatment for an eating disorder, and to compare ARFID patients to other eating disorder patients in the same cohort. A retrospective chart review of 7-17 year olds admitted to a day program for younger patients with eating disorders between 2008 and 2012 was performed. Patients with ARFID were compared to those with anorexia nervosa, bulimia nervosa, and other specified feeding or eating disorder/unspecified feeding or eating disorder with respect to demographics, anthropometrics, clinical symptoms, and psychometric testing, using Chi-square, ANOVA, and post-hoc analysis. 39/173 (22.5%) patients met ARFID criteria. The ARFID group was younger than the non-ARFID group and had a greater proportion of males. Similar degrees of weight loss and malnutrition were found between groups. Patients with ARFID reported greater fears of vomiting and/or choking and food texture issues than those with other eating disorders, as well as greater dependency on nutritional supplements at intake. Children's Eating Attitudes Test scores were lower for children with than without ARFID. A higher comorbidity of anxiety disorders, pervasive developmental disorder, and learning disorders, and a lower comorbidity of depression, were found in those with ARFID. This study demonstrates that there are significant demographic and clinical characteristics that differentiate children with ARFID from those with other eating disorders in a day treatment program, and helps substantiate the recognition of ARFID as a distinct eating disorder diagnosis in the DSM-5.

TARGETED TREATMENTS IN AUTISM AND FRAGILE X SYNDROME

Autism is a neurodevelopmental disorder consisting of a constellation of symptoms that sometimes occur as part of a complex disorder characterized by impairments in social interaction, communication and behavioral domains. It is a highly disabling disorder and there is a need for treatment targeting the core symptoms. Although autism is accepted as highly heritable, there is no genetic cure at this time. Autism is shown to be linked to several genes and is a feature of some complex genetic disorders, including fragile X syndrome (FXS), fragile X premutation involvement, tuberous sclerosis and Rett syndrome. The term autism spectrum disorders (ASDs) covers autism, Asperger syndrome and pervasive developmental disorders (PDD-NOS) and the etiologies are heterogeneous. In recent years, targeted treatments have been developed for several disorders that have a known specific genetic cause leading to autism. Since there are significant molecular and neurobiological overlaps among disorders, targeted treatments developed for a specific disorder may be helpful in ASD of unknown etiology. Examples of this are two drug classes developed to treat FXS, Arbaclofen, a GABAB agonist, and mGluR5 antagonists, and both may be helpful in autism without FXS. The mGluR5 antagonists are also likely to have a benefit in the aging problems of fragile X premutation carriers, the fragile X –associated tremor ataxia syndrome (FXTAS) and the Parkinsonism that can occur in aging patients with fragile X syndrome. Targeted treatments in FXS which has a well known genetic etiology may lead to new targeted treatments in autism. PMID:23162607

Selective serotonin reuptake inhibitors (SSRIs) are considered safe and are frequently used during pregnancy. However, two case-control studies suggested an association between prenatal SSRI exposure with childhood autism. To prospectively determine whether intra-uterine SSSRI exposure is associated with childhood autistic symptoms in a population-based study. A total of 376 children prenatally exposed to maternal depressive symptoms (no SSRI exposure), 69 children prenatally exposed to SSRIs and 5531 unexposed children were included. Child pervasive developmental and affective problems were assessed by parental report with the Child Behavior Checklist at ages 1.5, 3 and 6. At age 6, we assessed autistic traits using the Social Responsiveness Scale (n = 4264). Prenatal exposure to maternal depressive symptoms without SSRIs was related to both pervasive developmental (odds ratio (OR) = 1.44, 95% CI 1.07-1.93) and affective problems (OR = 1.44, 95% CI 1.15-1.81). Compared with unexposed children, those prenatally exposed to SSRIs also were at higher risk for developing pervasive developmental problems (OR = 1.91, 95% CI 1.13-3.47), but not for affective problems. Children prenatally exposed to SSRIs also had more autistic traits (B = 0.15, 95% CI 0.08-0.22) compared with those exposed to depressive symptoms only. Our results suggest an association between prenatal SSRI exposure and autistic traits in children. Prenatal depressive symptoms without SSRI use were also associated with autistic traits, albeit this was weaker and less specific. Long-term drug safety trials are needed before evidence-based recommendations are possible. Royal College of Psychiatrists.

Investigating sleep in mental disorders has the potential to reveal both disorder-specific and transdiagnostic psychophysiological mechanisms. This meta-analysis aimed at determining the polysomnographic (PSG) characteristics of several mental disorders. Relevant studies were searched through standard strategies. Controlled PSG studies evaluating sleep in affective, anxiety, eating, pervasive developmental, borderline and antisocial personality disorders, attention-deficit-hyperactivity disorder (ADHD), and schizophrenia were included. PSG variables of sleep continuity, depth, and architecture, as well as rapid-eye movement (REM) sleep were considered. Calculations were performed with the "Comprehensive Meta-Analysis" and "R" software. Using random effects modeling, for each disorder and each variable, a separate meta-analysis was conducted if at least 3 studies were available for calculation of effect sizes as standardized means (Hedges' g). Sources of variability, that is, sex, age, and mental disorders comorbidity, were evaluated in subgroup analyses. Sleep alterations were evidenced in all disorders, with the exception of ADHD and seasonal affective disorders. Sleep continuity problems were observed in most mental disorders. Sleep depth and REM pressure alterations were associated with affective, anxiety, autism and schizophrenia disorders. Comorbidity was associated with enhanced REM sleep pressure and more inhibition of sleep depth. No sleep parameter was exclusively altered in 1 condition; however, no 2 conditions shared the same PSG profile. Sleep continuity disturbances imply a transdiagnostic imbalance in the arousal system likely representing a basic dimension of mental health. Sleep depth and REM variables might play a key role in psychiatric comorbidity processes. Constellations of sleep alterations may define distinct disorders better than alterations in 1 single variable. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

microRNA and Autism.

Autism is a complex neurodevelopmental disorder characterized by deficiencies in social interaction and communication, and by repetitive and stereotyped behaviors. According to a recent report, the prevalence of this pervasive developmental disorder has risen to 1 in 88. This will have enormous public health implications in the future, and has necessitated the need to discover predictive biomarkers that could index for autism before the onset of symptoms. microRNAs (miRNAs) are small, noncoding RNAs that regulate gene expression at the posttranscriptional level. They have recently emerged as prominent epigenetic regulators of various cellular processes including neurodevelopment. They are abundantly present in the brain, and their dysfunction has been implicated in an array of neuropathological conditions including autism. miRNAs, previously known to be expressed only in cells and tissues, have also been detected in extracellular body fluids such as serum, plasma, saliva, and urine. Altered expression of cellular and circulating miRNAs have been observed in autistic individuals compared to healthy controls. miRNAs are now being considered as potential targets for the development of novel therapeutic strategies for autism.

Rett syndrome (RTT) is a pervasive developmental disorder, primarily affecting girls with a prevalence of 1 in every 10,000 births; it represents the second most common cause of intellectual disability in females. Mutations in the gene encoding methyl-CpG-binding protein 2 (MECP2) have been identified as clear etiological factors in more than 90% of classical RTT cases. Whereas the mechanisms leading to the severe, progressive and specific neurological dysfunctions when this gene is mutated still remain to be elucidated, a series of different mouse models have been generated, bearing different Mecp2 mutation. Neurobehavioural analysis in these mouse lines have been carried out and phenotyping analysis can be now utilised to preclinically evaluate the effects of potential RTT treatments. This review summarizes the different results achieved in this research field taking into account different key targets identified to ameliorate RTT phenotype in mouse models, including those not directly downstream of MeCP2 and those limited to the early phases of postnatal development.

Adolescent psychotic experiences (PEs) are common, and are associated with both psychotic and non-psychotic illnesses. In order to examine psychopathological and cognitive antecedents of adolescent PEs, we have conducted a longitudinal study of common childhood psychiatric disorders and subsequent adolescent PEs in the population-based prospective ALSPAC birth cohort. Depression, anxiety, attention deficit hyperactivity disorder, oppositional defiant or conduct disorder, and pervasive developmental disorder were diagnosed according to DSM-IV criteria in 8253 participants at age 8years. IQ was assessed by WISC-III also at 8years. PEs, depressive and anxiety symptoms were assessed at 13years. Logistic regression calculated odds ratio (OR) for PEs at 13years associated with psychiatric disorders at 8years. Linear regression calculated mean difference in IQ between groups with and without psychiatric disorder. Mediating effects of IQ, mood and anxiety symptoms on the psychiatric disorder-PEs relationship were examined. In total, 599 children were assessed to have a DSM-IV psychiatric disorder at 8years (7.2%). These children compared with those without any psychiatric disorder performed worse on all measures of IQ; adjusted mean difference in total IQ -6.17 (95% CI, -7.86, -4.48). Childhood psychiatric disorders were associated with PEs subsequently in adolescence; adjusted OR 1.96 (95% CI, 1.47-2.68). The association between psychiatric disorder and subsequent PEs was partly mediated by, independently, IQ deficit at 8years and depressive and anxiety symptoms at 13years. The findings indicate that adolescent PEs are associated with general cognitive ability and past and present psychopathological factors. Copyright © 2016 The Authors. Published by Elsevier Inc.

Knowledge about the presentation of psychopathology in preschool age and associated risk factors is fundamental to preventive intervention before schooling. To investigate the full spectrum of psychiatric diagnoses in general population children at the period of transition from preschool to school. A sample of 1585 children from the Copenhagen Child Cohort, CCC2000 aged 5-7 years was assessed using the Development and Well-Being Assessment (DAWBA) with diagnostic classification by experienced clinicians. Perinatal, sociodemographic and socio-economic data was obtained from Danish national registries. The prevalence of any ICD-10 psychiatric disorder was 5.7% (95%CI: 4.4-7.1). Pervasive developmental disorders (PDD) were found in 1.3% (95%CI: 0.8-1.8) and behavioural and hyperkinetic disorders were found in 1.5% (95%CI: 0.9-2.1) and 1.0% (95%CI: 0.4-1.6), respectively. Emotional disorders were found in 2.9% (95%CI: 1.9-40). More boys were diagnosed with PDD, behavioural disorders and tics. No gender differences were found in hyperactivity disorders (HD) and emotional disorders. Co-morbidity was frequent, in particular between HD and PDD, but also between HD and emotional disorder and behavioural disorder. Teenage mothers, single parents and low household income the first two years after the child's birth were associated with a three-to fourfold increased risk of psychiatric disorder in the child at age 5-7 years. The study results point to two "windows of opportunity" for prevention. In the earliest postnatal years, prevention should target families at socio-economic risk; and in the years before schooling, intervention should focus on children with symptoms of PDD, HD, and behavioural disorders.

ICD-10 classification in Danish child and adolescent psychiatry--have diagnoses changed after the introduction of ICD-10?

The aim was to test this in a nationwide register study of diagnoses used in child and adolescents psychiatry in Denmark. A larger number of different diagnoses were expected to be applied after the introduction of the 10th version of the International Classification of Diseases (ICD-10). Reflecting the time trend, we particularly expected an increase in the number of neuropsychiatric diagnoses. From the Danish Psychiatric Central Register data were drawn on clinical discharge diagnoses. All patients aged 0-15 years examined at psychiatric hospitals from 1995-2002 were included; 22,469 children and adolescents with a first contact were registered. The most frequent discharge diagnoses were pervasive development disorders (PDD; 11.9%), adjustment disorders (10.6%), conduct disorder (9.5%), emotional and anxiety disorders (7.6%), hyperkinetic disorders (7.3%), and specific developmental disorders (7.3%). We found a significant increase in the number of neuropsychiatric and affective diagnoses and a significant decrease in the number of adjustment, conduct and anxiety diagnoses during the study period. Of the 22,469 diagnoses, 45% were only partly specified according to ICD-10. Thirty-four per cent had diagnoses unspecified on the four-character level (Fxx.9) and 11% had Z-diagnoses. A larger number of different diagnoses and an increase in the use of neuropsychiatric diagnoses were seen after the introduction of ICD-10. Many diagnoses were only partly specified; consequently, a more detailed specification of the ICD-10 is still required.

The Parent-Child Play Scale was developed as a scale that complements the Parent-Child Feeding Scale, created by I. Chatoor et al. (1997), to evaluate mother-infant/toddler interactions in two different caregiving contexts of a young child's everyday life, specifically play and feeding. This Play Scale can be used with infants and toddlers ranging in age from 1 month to 3 years and provides reliable global ratings of mother-child interactions during 10 min of videotaped free-play in a laboratory setting. The scale consists of 32 mother and infant/toddler interactive behaviors which are rated by trained observers from videotaped observations. Four subscales are derived: Dyadic Reciprocity, Maternal Unresponsiveness to Infant's/Toddler's Cues, Dyadic Conflict, and Maternal Intrusiveness. Construct validity and interrater and test-retest reliability of the Play Scale have been demonstrated. This Play Scale discriminates between children with and without feeding disorders as well as between children with different subtypes of feeding disorders as defined by the Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood, Revised (DC:0-3R) (Feeding Disorder of State Regulation, Feeding Disorder of Caregiver-Infant Reciprocity, and Infantile Anorexia). It can be used for research or clinical practice in the diagnosis and treatment of early feeding problems, to assess the pervasiveness of mother-infant/toddler difficulties and to monitor changes following therapy. © 2018 Michigan Association for Infant Mental Health.

Autism spectrum disorders (ASDs) include autistic disorder, Asperger's disorder and pervasive developmental disorder. The manifestations of ASDs can have an important impact on learning and social functioning that may persist during adulthood. The aim here was to summarize the evidence from Cochrane systematic reviews on interventions for ASDs. Review of systematic reviews, conducted within the Discipline of Evidence-Based Medicine, Escola Paulista de Medicina, Universidade Federal de São Paulo. We included and summarized the results from Cochrane systematic reviews on interventions for ASDs. Seventeen reviews were included. These found weak evidence of benefits from acupuncture, gluten and casein-free diets, early intensive behavioral interventions, music therapy, parent-mediated early interventions, social skill groups, Theory of Mind cognitive model, aripiprazole, risperidone, tricyclic antidepressants and selective serotonin reuptake inhibitors (SSRI); this last only for adults. No benefits were found for sound therapies, chelating agents, hyperbaric oxygen therapy, omega-3, secretin, vitamin B6/magnesium and SSRI for children. Acupuncture, gluten and casein-free diets, early intensive behavioral interventions, music therapy, parent-mediated early interventions, social skill groups and the Theory of Mind cognitive model seem to have benefits for patients with autism spectrum disorders (very low to low-quality evidence). Aripiprazole, risperidone, tricyclic antidepressants and SSRI (this last only for adults) also showed some benefits, although associated with higher risk of adverse events. Experimental studies to confirm a link between probable therapies and the disease, and then high-quality long-term clinical trials, are needed.

Predictors of sense of coherence in typically developing adolescent siblings of individuals with autism spectrum disorder.

Children with autism spectrum disorder (ASD) may be a stressor for family members yet there is little published research on the impact of having a child with ASD on their typically developing (TD) adolescent siblings. According to Antonovsky's salutogenic model, a strong sense of coherence leads to the view that the stressor is a manageable challenge rather than a burden and promotes healthier adaptation. This study examines the relationship between stress, TD sibling resources and the sense of coherence in TD siblings. This quantitative mail-based study uses a survey methodology, analysing the responses of TD adolescent siblings (n = 96) of individuals with autism, Asperger's syndrome, or pervasive developmental disorder - not otherwise specified to several rating scales. Adolescent siblings, ages 11 to 18 years, completed the Adolescent Coping Orientation for Problem Experience (ACOPE), Network of Relationship Inventory - Social Provision Version (NRI-SPV), Youth Self Report (YSR), and Sense of Coherence (SOC) instruments; parents completed the Child Autism Rating Scale - 2nd Edition (CARS-2). The salutogenesis model was used to guide and inform this research. Findings suggested the following: (a) the stress of ASD severity and resource of adjustment are related in TD adolescent siblings; (b) TD sibling adjustment has a strong relationship with sense of coherence levels; and (c) a greater number of positive coping strategies buffer TD sibling coherence levels when ASD severity scores are high. ASD severity and TD adolescent sibling resources influence sense of coherence in adolescent TD siblings of individuals with ASD. © 2014 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

Atypical brain activation patterns during a face-to-face joint attention game in adults with autism spectrum disorder.

Joint attention behaviors include initiating one's own and responding to another's bid for joint attention to an object, person, or topic. Joint attention abilities in autism are pervasively atypical, correlate with development of language and social abilities, and discriminate children with autism from other developmental disorders. Despite the importance of these behaviors, the neural correlates of joint attention in individuals with autism remain unclear. This paucity of data is likely due to the inherent challenge of acquiring data during a real-time social interaction. We used a novel experimental set-up in which participants engaged with an experimenter in an interactive face-to-face joint attention game during fMRI data acquisition. Both initiating and responding to joint attention behaviors were examined as well as a solo attention (SA) control condition. Participants included adults with autism spectrum disorder (ASD) (n = 13), a mean age- and sex-matched neurotypical group (n = 14), and a separate group of neurotypical adults (n = 22). Significant differences were found between groups within social-cognitive brain regions, including dorsal medial prefrontal cortex (dMPFC) and right posterior superior temporal sulcus (pSTS), during the RJA as compared to SA conditions. Region-of-interest analyses revealed a lack of signal differentiation between joint attention and control conditions within left pSTS and dMPFC in individuals with ASD. Within the pSTS, this lack of differentiation was characterized by reduced activation during joint attention and relative hyper-activation during SA. These findings suggest a possible failure of developmental neural specialization within the STS and dMPFC to joint attention in ASD. Copyright © 2012 Wiley Periodicals, Inc.

Background We report on the validity of the computerized diagnoses of autism in a large case-control study investigating the possible association between autism and the measles, mumps and rubella vaccine in the UK using the General Practitioner Research Database (GPRD). We examined anonymized copies of all relevant available clinical reports, including general practitioners' (GP) notes, consultant, speech therapy and educational psychologists reports, on 318 subjects born between 1973 and 1997 with a diagnosis of autism or a related disorder recorded in their electronic general practice record. Methods Data were abstracted to a case validation form allowing for the identification of developmental symptoms relevant to the diagnosis of pervasive developmental disorders (PDDs). Information on other background clinical and familial features was also abstracted. A subset of 50 notes was coded independently by 2 raters to derive reliability estimates for key clinical characteristics. Results For 294 subjects (92.5%) the diagnosis of PDD was confirmed after review of the records. Of these, 180 subjects (61.2%) fulfilled criteria for autistic disorder. The mean age at first recording of a PDD diagnosis in the GPRD database was 6.3 years (SD = 4.6). Consistent with previous estimates, the proportion of subjects experiencing regression in the course of their development was 19%. Inter-rater reliability for the presence of a PDD diagnosis was good (kappa = .73), and agreement on clinical features such as regression, age of parental recognition of first symptoms, language delay and presence of epilepsy was also good (kappas ranging from .56 to 1.0). Conclusions This study provides evidence that the positive predictive value of a diagnosis of autism recorded in the GPRD is high. PMID:15113435

Tangled webs: tracing the connections between genes and cognition.

Fisher, Simon E

2006-09-01

The rise of molecular genetics is having a pervasive influence in a wide variety of fields, including research into neurodevelopmental disorders like dyslexia, speech and language impairments, and autism. There are many studies underway which are attempting to determine the roles of genetic factors in the aetiology of these disorders. Beyond the obvious implications for diagnosis, treatment and understanding, success in these efforts promises to shed light on the links between genes and aspects of cognition and behaviour. However, the deceptive simplicity of finding correlations between genetic and phenotypic variation has led to a common misconception that there exist straightforward linear relationships between specific genes and particular behavioural and/or cognitive outputs. The problem is exacerbated by the adoption of an abstract view of the nature of the gene, without consideration of molecular, developmental or ontogenetic frameworks. To illustrate the limitations of this perspective, I select two cases from recent research into the genetic underpinnings of neurodevelopmental disorders. First, I discuss the proposal that dyslexia can be dissected into distinct components specified by different genes. Second, I review the story of the FOXP2 gene and its role in human speech and language. In both cases, adoption of an abstract concept of the gene can lead to erroneous conclusions, which are incompatible with current knowledge of molecular and developmental systems. Genes do not specify behaviours or cognitive processes; they make regulatory factors, signalling molecules, receptors, enzymes, and so on, that interact in highly complex networks, modulated by environmental influences, in order to build and maintain the brain. I propose that it is necessary for us to fully embrace the complexity of biological systems, if we are ever to untangle the webs that link genes to cognition.

Behavioural and emotional disorders in childhood: A brief overview for paediatricians

Mental health problems in children and adolescents include several types of emotional and behavioural disorders, including disruptive, depression, anxiety and pervasive developmental (autism) disorders, characterized as either internalizing or externalizing problems. Disruptive behavioural problems such as temper tantrums, attention deficit hyperactivity disorder, oppositional, defiant or conduct disorders are the commonest behavioural problems in preschool and school age children. The routine Paediatric clinic or Family Medicine/General Practitioner surgery presents with several desirable characteristics that make them ideal for providing effective mental health services to children and adolescents. DSM-5 and ICD-10 are the universally accepted standard criteria for the classification of mental and behaviour disorders in childhood and adults. The age and gender prevalence estimation of various childhood behavioural disorders are variable and difficult to compare worldwide. A review of relevant published literature was conducted, including published meta-analyses and national guidelines. We searched for articles indexed by Ovid, PubMed, PubMed Medical Central, CINAHL, EMBASE, Database of Abstracts and Reviews, and the Cochrane Database of Systematic reviews and other online sources. The searches were conducted using a combination of search expressions including “childhood”, “behaviour”, “disorders” or “problems”. Childhood behaviour and emotional problems with their related disorders have significant negative impacts on the individual, the family and the society. They are commonly associated with poor academic, occupational, and psychosocial functioning. It is important for all healthcare professionals, especially the Paediatricians to be aware of the range of presentation, prevention and management of the common mental health problems in children and adolescents.

To evaluate whether early folic acid supplementation during pregnancy prevents diagnosis of autism spectrum disorders in offspring. Information on autism spectrum disorder diagnosis was obtained from the National Hospital Register and the Central Psychiatric Register. We estimated risk ratios for autism spectrum disorders for children whose mothers took folate or multivitamin supplements from 4 weeks prior from the last menstrual period through to 8 weeks after the last menstrual period (-4 to 8 weeks) by three 4-week periods. We did not find an association between early folate or multivitamin intake for autism spectrum disorder (folic acid-adjusted risk ratio: 1.06, 95% confidence interval: 0.82-1.36; multivitamin-adjusted risk ratio: 1.00, 95% confidence interval: 0.82-1.22), autistic disorder (folic acid-adjusted risk ratio: 1.18, 95% confidence interval: 0.76-1.84; multivitamin-adjusted risk ratio: 1.22, 95% confidence interval: 0.87-1.69), Asperger's syndrome (folic acid-adjusted risk ratio: 0.85, 95% confidence interval: 0.46-1.53; multivitamin-adjusted risk ratio: 0.95, 95% confidence interval: 0.62-1.46), or pervasive developmental disorder-not otherwise specified (folic acid-adjusted risk ratio: 1.07, 95% confidence interval: 0.75-1.54; multivitamin: adjusted risk ratio: 0.87, 95% confidence interval: 0.65-1.17) compared with women reporting no supplement use in the same period. We did not find any evidence to corroborate previous reports of a reduced risk for autism spectrum disorders in offspring of women using folic acid supplements in early pregnancy. © The Author(s) 2015.

Autistic disorder is a neuropsychiatric syndrome characterized by deficits in social interaction; qualitative impairments in communication; and restricted, repetitive, and stereotyped patterns of behavior, interests, or activities. It is classified as a type of pervasive developmental disorder (PDD). All PDDs have a qualitative impairment in social relatedness. However, many individuals with PDDs have interfering symptoms, including irritability (aggression, self-injurious behavior, and severe tantrums). Behavioral therapy is often helpful in decreasing these behaviors; however, sometimes adjunctive medications are needed, because of the intensity and severity of irritability. Numerous medications have been tested on patients with PDDs. Although many of these medications have been demonstrated to be useful, no clear main treatment for PDD has emerged. Despite the efficacy of some of the medicines, acceptability and side effects have proven to be barriers to their use. Yokukansan (TJ-54), a traditional Japanese medicine, is composed of seven kinds of dried herbs. It is widely prescribed in clinical situations for treating psychiatric disorders by acting mainly on the glutamatergic and serotonergic nervous system. Recent studies indicate that TJ-54 may be safe and useful in treating behavioral and psychological symptoms in dementia patients. We aimed at evaluating both the efficacy and the safety of TJ-54 in patients with PDDs. This was a 12 week prospective, open-label investigation of TJ-54 in 20 children and adolescents ages 6-17 years diagnosed with PDDs. Primary outcome measures included the Clinical Global Impressions-Improvement of Illness Scale (CGI-I), Children's Global Assessment Score (CGAS), and the Aberrant Behavior Checklist (ABC) irritability subscale. Twenty subjects, ages 6-17 years, received TJ-54 in the dosage range of 2.5-7.5 g/day. The CGI-I was significantly improved from 8 weeks (p<0.001). The mean CGAS was 31.92 at baseline, whereas the mean final score at 12 weeks was 54.52 (p<0.001). The ABC irritability/agitation subscale (subscale 1) was significantly improved from 8 weeks, and the hyperactivity/noncompliance subscale (subscale 4) was significantly improved in 12 weeks. TJ-54 was well tolerated. No subject left the study because of a drug-related adverse event. These preliminary data suggest that TJ-54 may be effective and well tolerated for the treatment of severe irritability/agitation and hyperactivity/noncompliance in children and adolescents ages 6-17 years with PDD. However, given the characteristics of this trial, the present findings should be taken cautiously, and larger-scale placebo-controlled studies are needed to elucidate the efficacy and tolerability of TJ-54 in this understudied population.

The number of cases diagnosed with developmental disorders is rapidly increasing among those consulting psychiatry clinics for the first time in their adulthood. The author presents the concept of developmental disorders, discusses how they can be differentiated from other psychiatric disorders, and proposes some treatments. From now on, all psychiatrists should know the difference between developmental disorders and other psychiatric disorders, and diagnose them multi-axially, including the dimension of development. They should always keep in mind how developmental disorders lead to difficulties in everyday life, and treat developmental disorders in conjunction with adequate environmental modifications along with the treatment of other comorbid psychiatric disorders.

Quantifying narrative ability in autism spectrum disorder: a computational linguistic analysis of narrative coherence.

PubMed

Losh, Molly; Gordon, Peter C

2014-12-01

Autism is a neurodevelopmental disorder characterized by serious difficulties with the social use of language, along with impaired social functioning and ritualistic/repetitive behaviors (American Psychiatric Association in Diagnostic and statistical manual of mental disorders: DSM-5, 5th edn. American Psychiatric Association, Arlington, 2013). While substantial heterogeneity exists in symptom expression, impairments in language discourse skills, including narrative (or storytelling), are universally observed in autism (Tager-Flusberg et al. in Handbook on autism and pervasive developmental disorders, 3rd edn. Wiley, New York, pp 335-364, 2005). This study applied a computational linguistic tool, Latent Semantic Analysis (LSA), to objectively characterize narrative performance in high-functioning individuals with autism and typically-developing controls, across two different narrative contexts that differ in the interpersonal and cognitive demands placed on the narrator. Results indicated that high-functioning individuals with autism produced narratives comparable in semantic content to those produced by controls when narrating from a picture book, but produced narratives diminished in semantic quality in a more demanding narrative recall task. This pattern is similar to that detected from analyses of hand-coded picture book narratives in prior research, and extends findings to an additional narrative context that proves particularly challenging for individuals with autism. Results are discussed in terms of the utility of LSA as a quantitative, objective, and efficient measure of narrative ability.

We reported the results of the 3-week summer treatment program (STP) for children with attention deficit hyperactivity disorder (ADHD) in 2006. The STP was based on methods established by Professor Pelham in Buffalo, NY and has been used in a number of studies and at a number of sites in the U.S. This is the first STP outside North America. Thirty-six children age 6-12 years with ADHD participated. The collection of evidence-based behavioral modification techniques that comprises the STP's behavioral program (e.g., point system, daily report card, positive reinforcement, time out) was used. Most children showed positive behavioral changes in multiple domains of functioning, demonstrated by significant improvement in points earned daily, which reflect behavior frequencies. Only one child with ADHD co-morbid with pervasive developmental disorder required an individualized program for excessive time outs. The ADHD rating scale, symptoms of oppositional defiant disorder, and hyperactivity/inattention in Strength and Difficulties Questionnaires evaluated by parents significantly improved after STP. Although the 3-week STP was much shorter than most STPs run in the U.S., the program is more intensive than typical outpatient treatment, providing 105h of intervenion in 3 weeks. The short-term effect of the STP was demonstrated for Japanese children with ADHD. 2008 Elsevier B.V. All rights reserved.

On the basis of the most recent epidemiologic research, Autism Spectrum Disorder (ASD) affects approximately 1% to 2% of all children. (1)(2) On the basis of some research evidence and consensus, the Modified Checklist for Autism in Toddlers isa helpful tool to screen for autism in children between ages 16 and 30 months. (11) The Diagnostic Statistical Manual of Mental Disorders, Fourth Edition, changes to a 2-symptom category from a 3-symptom category in the Diagnostic Statistical Manual of Mental Disorders, Fifth Edition(DSM-5): deficits in social communication and social interaction are combined with repetitive and restrictive behaviors, and more criteria are required per category. The DSM-5 subsumes all the previous diagnoses of autism (classic autism, Asperger syndrome, and pervasive developmental disorder not otherwise specified) into just ASDs. On the basis of moderate to strong evidence, the use of applied behavioral analysis and intensive behavioral programs has a beneficial effect on language and the core deficits of children with autism. (16) Currently, minimal or no evidence is available to endorse most complementary and alternative medicine therapies used by parents, such as dietary changes (gluten free), vitamins, chelation, and hyperbaric oxygen. (16) On the basis of consensus and some studies, pediatric clinicians should improve their capacity to provide children with ASD a medical home that is accessible and provides family-centered, continuous, comprehensive and coordinated, compassionate, and culturally sensitive care.

Cholinergic abnormalities in autism: is there a rationale for selective nicotinic agonist interventions?

PubMed

Deutsch, Stephen I; Urbano, Maria R; Neumann, Serina A; Burket, Jessica A; Katz, Elionora

2010-05-01

The core dysfunctions of autism spectrum disorders, which include autistic disorder, Asperger disorder, and pervasive developmental disorder not otherwise specified, include deficits in socialization and communication and a need for the preservation of "sameness;" intellectual impairment and epilepsy are common comorbidities. Data suggest that pathological involvement of cholinergic nuclei and altered expression of acetylcholine receptors, particularly nicotinic acetylcholine receptors, occur in brain of persons with autistic disorder. However, many of these studies involved postmortem tissue from small samples of primarily adult persons. Thus, the findings may reflect compensatory changes and may relate more closely to intellectual impairment and the confounding effects of seizures and medications, as opposed to the core dysfunctions of autism. Nonetheless, because of the roles played by acetylcholine receptors in general, and nicotinic acetylcholine receptors in particular, in normal processes of attention, cognition, and memory, selective cholinergic interventions should be explored for possible therapeutic effects. Additionally, there are electrophysiological data that complement the clinical observations of frequent comorbid seizure disorders in these patients, suggesting a disturbance in the balance of excitatory and inhibitory tone in the brains of persons with autistic disorders. Conceivably, because the alpha7 nicotinic acetylcholine receptor is located on the surface of gamma-aminobutyric acid inhibitory neurons, selective stimulation of this receptor would promote gamma-aminobutyric acid's release and restore diminished inhibitory tone. The development of agonists and partial agonists for nicotinic acetylcholine receptors and positive allosteric modulators that enhance the efficiency of coupling between the binding of agonist and channel opening should facilitate consideration of clinical trials.

Our aim was to examine the characteristics of EEG findings and epilepsy in autistic spectrum disorders (ASD) and the associated clinical and familial risk factors. Fifty-seven children (86% male) with ASD, mean age 82+/-36.2 months, were included in the study. Thirty-nine (68.4%) children had the diagnosis of autism, 15 (26.3%) had Pervasive Developmental Disorder Not Otherwise Specified, and 3 (5.3%) had high-functioning autism. One hour of sleep and/or awake EEG recordings was obtained for each child. All patients were evaluated with respect to clinical and familial characteristics and with the Childhood Autism Rating Scale, the Autism Behavior Checklist, and the Aberrant Behavior Checklist. The frequency of interictal epileptiform EEG abnormalities (IIEAs) was 24.6% (n=14), and the frequency of epilepsy was 14.2% (n=8). IIEAs were associated with a diagnosis of epilepsy (P=0.0001), Childhood Autism Rating Scale Activity scores (P=0.047), and a history of asthma and allergy (P=0.044). Epilepsy was associated with a family history of epilepsy (P=0.049) and psychiatric problems in the mother during pregnancy (P=0.0026). Future studies with larger samples will help to clarify the possible associations of epilepsy/IIEAs with asthma/allergy, hyperactivity, and familial factors in ASD. (c) 2009 Elsevier Inc.

A gluten- and casein-free diet is often given to children with autism spectrum disorder (ASD). We aimed to determine the effect of gluten and casein supplementation on maladaptive behaviour, gastrointestinal symptom severity and intestinal fatty acids binding protein (I-FABP) excretion in children with ASD. A randomised, controlled, double-blind trial was performed on 74 children with ASD with severe maladaptive behaviour and increased urinary I-FABP. Subjects were randomised to receive gluten-casein or a placebo for seven days. We evaluated maladaptive behaviour before and after supplementation, using I-FABP excretion, the approach withdrawal problem composite subtest of the Pervasive Developmental Disorder Behavior Inventory and the Gastrointestinal Symptom Severity Index. The mean approach withdrawal problem composite score was significantly higher before supplementation than after, both in the placebo and in the gluten-casein group. However, the mean difference was not significant and may have been caused by additional therapy. There was no significant difference in gastrointestinal symptoms and urinary I-FABP excretion. Administrating gluten-casein to children with ASD for one week did not increase maladaptive behaviour, gastrointestinal symptom severity or urinary I-FABP excretion. The effect of prolonged administration or other mechanisms of enterocyte damage in ASD should be explored. ©2015 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

Autism spectrum disorders: head circumference and body length at birth are both relative.

Although the body length and weight of an infant are related to head circumference, little research on ASDs has examined these factors. Our study compared the head circumferences of neonates who were later diagnosed with ASD with a control group. Additional comparisons on morphological disproportions at birth included the head circumference-to-height and head circumference-to-weight ratios. We recruited 422 children with ASD and 153 typically developing children. Head circumference, body length and weight at birth were collected and standardized as percentile scores according to gestational age and gender. Our results revealed that genuine macrocephaly was significantly higher in children with other pervasive developmental disorders compared with the control group. This difference was not observed with regard to genuine microcephaly. Relative macrocephaly and relative microcephaly were significantly more frequent in children with autism disorder compared with the control group with regard to body length. The differences in relative macrocephaly and microcephaly, as well as in other parameters, between diagnostic subgroups suggest that the presence of several neurological mechanisms plays a role in the later expression of different phenotypes. An increased head circumference-to-body length ratio in newborns may be a factor to follow that could be related to ASD. ©2013 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

Characteristic symptoms of autistic disorder (AD) can be the result of cognitive impairment which can be produced by specific neurological irregularities. Up until now a specific cognitive deficit in autism has not been found, although the majority of people with autism show intellectual impairment, verbal scores lower than manipulative measures and executive dysfunctions. A neuropsychological evaluation of children with AD was planned. These children had intellectual abilities in the normal range. They were compared with two other groups, one with pervasive developmental disorder not otherwise specified (PDD-NS), and the other from the general population. A battery of neuropsychological tests was carried out on five boys AD, five boys PDD-NS, and five boys of the general population. All of them were between 9 and 15 years old and their intellectual abilities were within the normal range. The children AD obtained verbal scores lower than their visual-perception scores. They also showed good dynamic coordination of movement. Scores in episodic memory tasks where executive strategies are needed were low. The characteristics described in the paper do not demonstrate a specific profile of the AD, but they can be useful in diagnoses and in planning treatment.

Parent and family impact of autism spectrum disorders: a review and proposed model for intervention evaluation.

PubMed

Karst, Jeffrey S; Van Hecke, Amy Vaughan

2012-09-01

Raising a child with an autism spectrum disorder (ASD) can be an overwhelming experience for parents and families. The pervasive and severe deficits often present in children with ASD are associated with a plethora of difficulties in caregivers, including decreased parenting efficacy, increased parenting stress, and an increase in mental and physical health problems compared with parents of both typically developing children and children with other developmental disorders. In addition to significant financial strain and time pressures, high rates of divorce and lower overall family well-being highlight the burden that having a child with an ASD can place on families. These parent and family effects reciprocally and negatively impact the diagnosed child and can even serve to diminish the positive effects of intervention. However, most interventions for ASD are evaluated only in terms of child outcomes, ignoring parent and family factors that may have an influence on both the immediate and long-term effects of therapy. It cannot be assumed that even significant improvements in the diagnosed child will ameliorate the parent and family distress already present, especially as the time and expense of intervention can add further family disruption. Thus, a new model of intervention evaluation is proposed, which incorporates these factors and better captures the transactional nature of these relationships.

Concern has been raised about possible increases in the prevalence of autism. However, few population-based studies have been conducted in the United States. To determine the prevalence of autism among children in a major US metropolitan area and to describe characteristics of the study population. Study of the prevalence of autism among children aged 3 to 10 years in the 5 counties of metropolitan Atlanta, Ga, in 1996. Cases were identified through screening and abstracting records at multiple medical and educational sources, with case status determined by expert review. Autism prevalence by demographic factors, levels of cognitive functioning, previous autism diagnoses, special education eligibility categories, and sources of identification. A total of 987 children displayed behaviors consistent with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria for autistic disorder, pervasive developmental disorder-not otherwise specified, or Asperger disorder. The prevalence for autism was 3.4 per 1000 (95% confidence interval [CI], 3.2-3.6) (male-female ratio, 4:1). Overall, the prevalence was comparable for black and white children (black, 3.4 per 1000 [95% CI, 3.0-3.7] and white, 3.4 per 1000 [95% CI, 3.2-3.7]). Sixty-eight percent of children with IQ or developmental test results (N = 880) had cognitive impairment. As severity of cognitive impairment increased from mild to profound, the male-female ratio decreased from 4.4 to 1.3. Forty percent of children with autism were identified only at educational sources. Schools were the most important source for information on black children, children of younger mothers, and children of mothers with less than 12 years of education. The rate of autism found in this study was higher than the rates from studies conducted in the United States during the 1980s and early 1990s, but it was consistent with those of more recent studies.

This study aimed at investigating the use of psychosocial interventions and psychotropic co-medication among stimulant-treated children with attention-deficit hyperactivity disorder (ADHD) in relation to the presence of psychiatric co-morbidity. Stimulant users younger than 16 years were identified in 115 pharmacies and a questionnaire was sent to their stimulant prescribing physician. Of 773 questionnaires sent out, 556 were returned and were suitable for analysis (72%). The results are based on 510 questionnaires concerning stimulant-treated children for whom a diagnosis of ADHD was reported. Of the 510 children diagnosed with ADHD, 31% had also received one or more other psychiatric diagnoses, mainly pervasive developmental disorder or oppositional defiant disorder/conduct disorder. We found an association between the presence of co-morbidity and the use of psychosocial interventions for the child (P < 0.001) and the parents (P < 0.001). In the ADHD-only group, 26% did not receive any form of additional interventions, while psychosocial interventions varied from 8 to 18% in children with ADHD and psychiatric co-morbidity. The presence of diagnostic co-morbidity was also associated with the use of psychotropic co-medication (overall, P = 0.012) and antipsychotics (P < 0.001). Stimulant-treated youths with ADHD and psychiatric co-morbidity received more psychosocial interventions and psychotropic co-medication than children with ADHD-only. The type of psychosocial interventions and psychotropic co-medication received by the children and their parents, depended on the specific co-morbid psychiatric disorder being present.

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

Within the new DSM-5, the currently differentiated subgroups of "Autistic Disorder" (299.0), "Asperger's Disorder" (299.80) and "Pervasive Developmental Disorder" (299.80) are replaced by the more general "Autism Spectrum Disorder". With regard to a patient-oriented and expedient advising therapy planning, however, the issue of an empirically reproducible and clinically feasible differentiation into subgroups must still be raised. Based on two Autism-rating-scales (ASDS and FSK), an exploratory two-step cluster analysis was conducted with N=103 children (age: 5-18) seen in our social-pediatric health care centre to examine potentially autistic symptoms. In the two-cluster solution of both rating scales, mainly the problems in social communication grouped the children into a cluster "with communication problems" (51 % and 41 %), and a cluster "without communication problems". Within the three-cluster solution of the ASDS, sensory hypersensitivity, cleaving to routines and social-communicative problems generated an "autistic" subgroup (22%). The children of the second cluster ("communication problems", 35%) were only described by social-communicative problems, and the third group did not show any problems (38%). In the three-cluster solution of the FSK, the "autistic cluster" of the two-cluster solution differentiated in a subgroup with mainly social-communicative problems (cluster 1) and a second subgroup described by restrictive, repetitive behavior. The different cluster solutions will be discussed with a view to the new DSM-5 diagnostic criteria, for following studies a further specification of some of the ASDS and FSK items could be helpful.

This review evaluates the DSM-IV criteria of social anxiety disorder (SAD), with a focus on the generalized specifier and alternative specifiers, the considerable overlap between the DSM-IV diagnostic criteria for SAD and avoidant personality disorder, and developmental issues. A literature review was conducted, using the validators provided by the DSM-V Spectrum Study Group. This review presents a number of options and preliminary recommendations to be considered for DSM-V. Little supporting evidence was found for the current specifier, generalized SAD. Rather, the symptoms of individuals with SAD appear to fall along a continuum of severity based on the number of fears. Available evidence suggested the utility of a specifier indicating a "predominantly performance" variety of SAD. A specifier based on "fear of showing anxiety symptoms" (e.g., blushing) was considered. However, a tendency to show anxiety symptoms is a core fear in SAD, similar to acting or appearing in a certain way. More research is needed before considering subtyping SAD based on core fears. SAD was found to be a valid diagnosis in children and adolescents. Selective mutism could be considered in part as a young child's avoidance response to social fears. Pervasive test anxiety may belong not only to SAD, but also to generalized anxiety disorder. The data are equivocal regarding whether to consider avoidant personality disorder simply a severe form of SAD. Secondary data analyses, field trials, and validity tests are needed to investigate the recommendations and options.

Previous studies in three independent cohorts have shown that the rs1858830 C allele variant in the promoter region of the MET gene on chromosome 7q31 is associated with autism. Another study has found correlations between other alterations in the MET gene and autism in two unrelated cohorts. This study screened two cohorts, an Autistic Disorder cohort from South Carolina and a Pervasive Developmental Disorder (PDD) cohort from Italy, for the presence of the C allele variant in rs1858830. A significant increase in the C allele variant frequency was found in the South Carolina Autistic Disorder patients as compared to South Carolina Controls (chi(2)=5.8, df=1, P=0.02). In the South Carolina cohort, a significant association with Autistic Disorder was found when comparing the CC and CG genotypes to the GG genotype (odds ratio (OR)=1.64; 95% confidence interval (CI)=1.12-2.40; chi(2)=6.5, df=1, P=0.01) in cases and controls. In the Italian cohort, no significant association with PDD was found when comparing the CC or CG genotype to the GG genotype (OR=1.20; 95% CI=0.56-2.56; chi(2)=0.2, df=1, P=0.64). This study is the third independent study to find the rs1858830 C variant in the MET gene promoter to be associated with autism.

Pervasive, Coordinated Protein-Level Changes Driven by Transcript Isoform Switching during Meiosis.

To better understand the gene regulatory mechanisms that program developmental processes, we carried out simultaneous genome-wide measurements of mRNA, translation, and protein through meiotic differentiation in budding yeast. Surprisingly, we observed that the levels of several hundred mRNAs are anti-correlated with their corresponding protein products. We show that rather than arising from canonical forms of gene regulatory control, the regulation of at least 380 such cases, or over 8% of all measured genes, involves temporally regulated switching between production of a canonical, translatable transcript and a 5' extended isoform that is not efficiently translated into protein. By this pervasive mechanism for the modulation of protein levels through a natural developmental program, a single transcription factor can coordinately activate and repress protein synthesis for distinct sets of genes. The distinction is not based on whether or not an mRNA is induced but rather on the type of transcript produced. Copyright © 2018 Elsevier Inc. All rights reserved.

Genetic Influence on the Expression of Hand Preferences in Chimpanzees (Pan Troglodytes): Evidence in Support of the Right-Shift Theory and Developmental Instability

PubMed Central

Hopkins, William D.; Dahl, Jeremy F.; Pilcher, Dawn

2007-01-01

Genetic mechanisms have been proposed to explain the pervasive representation of right-handedness in humans, whereas random, nongenetic factors have been posited to explain the lack of population-level right-handedness in nonhuman primates. We report evidence that hand preferences in chimpanzees are heritable, even among related individuals raised in different environments. Furthermore, we report that the degree of heritability is modified by factors associated with developmental instability, notably, offspring parity. The data are interpreted to reconcile both genetic models for handedness and hypotheses suggesting that developmental instability influences variation in handedness. PMID:11476096

Onto-clust--a methodology for combining clustering analysis and ontological methods for identifying groups of comorbidities for developmental disorders.

Children with developmental disorders usually exhibit multiple developmental problems (comorbidities). Hence, such diagnosis needs to revolve on developmental disorder groups. Our objective is to systematically identify developmental disorder groups and represent them in an ontology. We developed a methodology that combines two methods (1) a literature-based ontology that we created, which represents developmental disorders and potential developmental disorder groups, and (2) clustering for detecting comorbid developmental disorders in patient data. The ontology is used to interpret and improve clustering results and the clustering results are used to validate the ontology and suggest directions for its development. We evaluated our methodology by applying it to data of 1175 patients from a child development clinic. We demonstrated that the ontology improves clustering results, bringing them closer to an expert generated gold-standard. We have shown that our methodology successfully combines an ontology with a clustering method to support systematic identification and representation of developmental disorder groups.

[Autism spectrum disorder and suicidality].

Huguet, G; Contejean, Y; Doyen, C

Most studies on suicide exclude subjects with autism spectrum disorders, yet there is a risk group. The purpose of this article is to present the data in the literature regarding the clinical and epidemiological characteristics of suicidality in subjects with autism spectrum disorders and to identify the factors that promote the transition to action. This review was carried out using the data set collected in Medline PubMed, items with "autism spectrum disorder", "pervasive developmental disorder", "Asperger's syndrome", "suicide", "suicide attempt", and "suicide behavior". In all subjects from our research on PubMed, 21.3% of subjects with autism spectrum disorder reported suicidal ideation, have attempted suicide or died by suicide (115 out of 539 subjects) and 7.7% of subjects supported for suicidal thoughts or attempted suicide exhibited an autism spectrum disorder (62 out of 806 subjects), all ages combined. Suicidal ideation and morbid preoccupation are particularly common in adolescents and young adults. Suicide attempts are accompanied by a willingness for death and can lead to suicide. They are more common in high-functioning autism and Asperger subjects. The methods used are often violent and potentially lethal or fatal in two cases published. Suicide risk depends on many factors that highlight the vulnerability of these subjects, following autistic and developmental symptoms. Vulnerability complicating the diagnosis of comorbid depressive and anxiety disorders are major factors associated with suicidality. Vulnerability but also directly related to suicidality, since the origin of physical and sexual abuse and victimization by peers assigning them the role of "scapegoat" are both responsible for acting out. Given the diversity of factors involved in the risk of suicide in this population, this does not validate "a" program of intervention, but the intervention of "customized programs". Their implementation should be as early as possible in order to treat while the brain has the greatest plasticity. The aim is to provide the necessary access to the greatest possible autonomy. Hence, including working communication skills and interaction, these subject will have independent means of protection, an essential complement to measures to protect vulnerable subjects; the vulnerability of direct and indirect suicidality. Comorbid diagnoses must take into account the specificities of these patients, their difficulties in communicating their mental state, and adapted and innovative therapeutic strategies must be offered and validated.

Autism spectrum disorder (ASD) is a lifelong neurodevelopmental disorder. The authors conducted a study to evaluate the demographics, caries experience and behavior of patients with ASD and compare these characteristics with those of patients without ASD (unaffected patients). The authors reviewed patients' charts and identified a group of 395 patients with ASD and a group of 386 unaffected patients. They obtained the following patient data for analysis: primary diagnosis, age, sex, residence (home versus institution or group home), presence of seizure disorder, additional diagnosis (mental retardation, cerebral palsy, self-injurious behavior or pica), medications, caries prevalence, caries severity and behavior. The ASD group had a male:female ratio of 4:1, and patients had a diagnosis of autism, pervasive developmental disorder-not otherwise specified or Asperger syndrome. Sex distribution was equal in the unaffected group, which was younger and had a higher decayed, missing and filled teeth (DMFT) score than did the ASD group. When the authors controlled for age and sex, they noted a statistically significant association between ASD and dental caries prevalence. A significantly higher percentage of patients with ASD than unaffected patients were uncooperative and required dental treatment to take place under general anesthesia. Caries prevalence and severity in patients with ASD were not associated with institutionalization, presence of seizure disorder or additional diagnosis. People with ASD were more likely to be caries-free and had lower DMFT scores than did their unaffected peers. Significantly more patients with ASD than unaffected patients were uncooperative and required general anesthesia to undergo dental treatment.

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by behavioral impairment in social interactions. Although theoretical and empirical evidence suggests that impairment in the social brain network could be the neural underpinnings of ASD, previous structural magnetic resonance imaging (MRI) studies in adults with ASD have not provided clear support for this, possibly due to confounding factors, such as language impairments. To further explore this issue, we acquired structural MRI data and analyzed gray matter volume in adults with ASD (n = 36) who had no language impairments (diagnosed with Asperger’s disorder or pervasive developmental disorder not otherwise specified, with symptoms milder than those of Asperger’s disorder), had no comorbidity, and were not taking medications, and in age- and sex-matched typically developing (TD) controls (n = 36). Univariate voxel-based morphometry analyses revealed that regional gray matter volume was lower in the ASD than in the control group in several brain regions, including the right inferior occipital gyrus, left fusiform gyrus, right middle temporal gyrus, bilateral amygdala, right inferior frontal gyrus, right orbitofrontal cortex, and left dorsomedial prefrontal cortex. A multivariate approach using a partial least squares (PLS) method showed that these regions constituted a network that could be used to discriminate between the ASD and TD groups. A PLS discriminant analysis using information from these regions showed high accuracy, sensitivity, specificity, and precision (>80%) in discriminating between the groups. These results suggest that reduced gray matter volume in the social brain network represents the neural underpinnings of behavioral social malfunctioning in adults with ASD. PMID:28824399

Gene-Environment Interplay between Parent-Child Relationship Problems and Externalizing Disorders in Adolescence and Young Adulthood

Background Previous studies have shown that genetic risk for externalizing (EXT) disorders is greater in the context of adverse family environments during adolescence, but it is unclear whether these effects are long-lasting. The current study evaluated developmental changes in gene-environment interplay in the concurrent and prospective associations between parent-child relationship problems and EXT at ages 18 and 25. Method The sample included 1,382 twin pairs (48% male) from the Minnesota Twin Family Study, participating in assessments at ages 18 (M = 17.8 years, SD = 0.69) and 25 (M = 25.0 years, SD = 0.90). Perceptions of parent-child relationship problems were assessed using questionnaires. Structured interviews were used to assess symptoms of adult antisocial behavior and nicotine, alcohol, and illicit drug dependence. Results We detected a gene-environment interaction at age 18, such that the genetic influence on EXT was greater in the context of more parent-child relationship problems. This moderation effect was not present at age 25, nor did parent-relationship problems at age 18 moderate genetic influence on EXT at age 25. Rather, common genetic influences accounted for this longitudinal association. Conclusions Gene-environment interaction evident in the relationship between adolescent parent-child relationship problems and EXT is both proximal and developmentally limited. Common genetic influence, rather than a gene-environment interaction, accounts for the long-term association between parent-child relationship problems at age 18 and EXT at age 25. These results are consistent with a relatively pervasive importance of gene-environmental correlation in the transition from late adolescence to young adulthood. PMID:25066478

Objective Changes in autism diagnostic criteria found in DSM5 may affect Autism Spectrum Disorder (ASD) prevalence, research findings, diagnostic processes and eligibility for clinical and other services. Utilizing our published, total-population Korean prevalence data, we compute DSM5 ASD and Social Communication Disorder (SCD) prevalence and compare them to DSMIV Pervasive Developmental Disorder (PDD) prevalence estimates. We also describe individuals previously diagnosed with DSMIV PDD when diagnoses change with DSM-5 criteria. Method The target population was all 7-12-year-old children in a South Korean community (N= 55,266), those in regular and special education schools and a disability registry. We utilized the Autism Spectrum Screening Questionnaire for systematic, multi-informant screening. Parents of screen-positive children were offered comprehensive assessments using standardized diagnostic procedures, including the Autism Diagnostic Interview-Revised and Autism Diagnostic Observation Schedule. Best estimate clinical diagnoses were made using DSMIV PDD and DSM5 ASD and SCD criteria. Results DSM5 ASD estimated prevalence is 2.20% (CI: 1.77-3.64). Combined DSM-5 ASD and SCD prevalence is virtually same as DSM-IV PDD prevalence (2.64%). Most children with Autistic Disorder (99%), Asperger Disorder (92%), and PDD NOS (63%) met DSM-5 ASD criteria, whereas 1%, 8% and 32%, respectively, met SCD criteria. All remaining children (2% ) had other psychopathology, principally Attention Deficit Hyperactivity Disorder and anxiety disorder. Conclusion Our findings suggest that most individuals with a prior DSMIV PDD meet DSM5 diagnostic criteria for ASD and SCD. PDD, ASD or SCD, extant diagnostic criteria identify a large, clinically meaningful group of individuals and families who require evidence-based services. PMID:24745950

Objective To provide the first longitudinal characterization of mood and psychosocial functioning in youth with comorbid bipolar (BD) and autism spectrum (ASD) disorders. Method The Course and Outcome of Bipolar Youth study followed 368 youth (7–17 years) with DSM-IV bipolar I (BP-I), -II, or Not Otherwise Specified (NOS) for, on average, 9 years using the Longitudinal Interval Follow-up Evaluation. This subgroup analysis compared youth with and without ASD on clinical presentation, percentage of time with mood symptomatology, and psychosocial functioning. Results Thirty youth (~8%) met DSM-IV criteria for Asperger disorder or pervasive developmental disorder-NOS (referred to here as ASD). Lifetime worst episode severity was similar in both groups, but youth with both BD and ASD (BD+ASD) had elevated rates of comorbid attention-deficit/hyperactivity and obsessive-compulsive disorders, were younger at intake, and had an earlier onset of mood symptoms. Over time, in both groups, the proportion of predominantly euthymic youth increased, and episode recurrence decreased. Compared to youth with BD, the clinical presentation of youth with BD+ASD more frequently involved distractibility, racing thoughts, depressed mood, social withdrawal, and low reactivity of negative mood states. ASD-related symptomatic differences were generally strongest early and decreased over time. Youth with BD+ASD had significantly greater impairment in friendships throughout follow-up. Conclusion Youth with BD+ASD exhibit typical BD mood symptoms but with earlier onset, mixed symptom presentation, and additive functional impairments. Significant amelioration of clinical symptoms occurred over time, suggesting that early recognition and treatment of mood disorders in youth with ASD may improve clinical outcomes. PMID:27871641

To determine the profile of children and adolescents diagnosed with autism spectrum disorder (ASD) in a comprehensive care centre in Bogota, Colombia. A descriptive-correlational study with a sample of patients who had attended the institution from 2003 to 2009. Demographic and clinical aspects were evaluated and a correlation between the diagnosis and severity being analysed in search for risk factors. A total of 138 patients were studied. The average age of onset was 21 months, and diagnosis had been made at 45 months. There was a male predominance (6.15:1). The predominant diagnosis was autistic syndrome (83%), followed by pervasive developmental disorder not otherwise specified (17%). There was no pathological background in the family history, during pregnancy or during the neonatal period. Motor development during the first year was normal but acquisition of language skills was compromised. The specific signs of ASD as regards the disorder in itself, communication skills, spontaneous speech, verbal comprehension, attention, imitation, use of objects, self-care and symbolic play were significantly related to the severity of the disease. Diagnosis of ASD is still delayed in our population and usually after referral from someone other than a health professional. The most important problems were found in communication skills and relationships with peers. The study did not show significant associated risk factors.

In this study, we prospectively examined developmental trajectories of five anxiety disorder symptom dimensions (generalized anxiety disorder, panic disorder, school anxiety, separation anxiety disorder, and social anxiety disorder) from early to late adolescence in a community sample of 239 adolescents, assessed annually over 8 years. Latent growth modeling indicated different developmental trajectories from early into late adolescence for the different anxiety disorder symptoms, with some symptoms decreasing and other symptoms increasing over time. Sex differences in developmental trajectories were found for some symptoms, but not all. Furthermore, latent class growth analysis identified a normal developmental profile (including a majority of adolescents reporting persistent low anxiety disorder symptoms over 8 years) and an at-risk developmental profile (including a minority of adolescents reporting persistent high anxiety disorder symptoms over 8 years) for all of the anxiety disorder symptom dimensions except panic disorder. Additional analyses longitudinally supported the validity of these normal and at-risk developmental profiles and suggested differential associations between different anxiety disorder symptom dimensions and developmental trajectories of substance use, parenting, and identity development. Taken together, our results emphasize the importance of examining separate dimensions of anxiety disorder symptoms in contrast to a using a global, one-dimensional approach to anxiety.

Autism spectrum disorders (ASD) affect approximately 1 in 150 children across the U.S., and are characterized by abnormal social actions, language difficulties, repetitive or restrictive behaviors, and special interests. ASD include autism (autistic disorder), Asperger syndrome, and Pervasive Developmental Disorder not otherwise specified (PDD-NOS or atypical autism). High-functioning individuals may communicate with moderate-to-high language skills, although difficulties in social skills may result in communication deficits. Low-functioning individuals may have severe deficiencies in language, resulting in poor communication between the individual and others. Behavioral intervention programs have been developed for ASD, and are frequently adjusted to accommodate specific individual needs. Many of these programs are school-based and aim to support the child in the development of their skills, for use outside the classroom with family and friends. Strides are being made in understanding the factors contributing to the development of ASD, particularly the genetic contributions that may underlie these disorders. Mutant mouse models provide powerful research tools to investigate the genetic factors associated with ASD and its co-morbid disorders. In support, the BTBR T+tf/J mouse strain incorporates ASD-like social and communication deficits and high levels of repetitive behaviors. This commentary briefly reviews the reciprocal relationship between observations made during evidence-based behavioral interventions of high- versus low-functioning children with ASD and the accumulating body of research in autism, including animal studies and basic research models. This reciprocity is one of the hallmarks of the scientific method, such that research may inform behavioral treatments, and observations made during treatment may inform subsequent research.

Although several previous studies have been conducted, the neural basis of autism spectrum disorder (ASD) is poorly understood. The objective of the present study was to determine whether individuals with ASD have altered brain chemical metabolites and whether such alterations are related to their autistic symptoms. N-acetylaspartate (NAA)/creatine (Cr) and choline/Cr ratios in the right medial temporal lobe (MTL), medial prefrontal cortex, and cerebellar vermis were measured in 38 individuals with ASD (mean age = 12.9 years), including 12 with autism, 15 with Asperger's Disorder, and 11 with pervasive developmental disorder not otherwise specified (PDD-NOS), and 16 matched healthy control subjects (mean age = 11.5 years) with proton magnetic resonance spectroscopy. Autistic symptoms were assessed by the Childhood Autistic Rating Scale-Tokyo Version. There was a significant group difference for NAA/Cr ratio in the right MTL between the autism, Asperger's Disorder, PDD-NOS, and control groups (p < .001), and the autism group had a significantly lower NAA/Cr ratio compared with the PDD-NOS (p < .001) and control (p < .001) groups. In the ASD group, there was a significant negative correlation between NAA/Cr ratio in the right MTL and their Childhood Autistic Rating Scale-Tokyo Version total scores (r = -.44, p = .01) and subscales of emotional response (r = -.38, p = .02) and listening response (r = -.54, p = .001). The results of the present study suggest that subjects with ASD have abnormalities of neural integrity in the amygdala-hippocampus region that are related to their severity and social impairments.

Prader-Willi syndrome (PWS) is a neuro-genetic disorder caused by the absence/loss of expression of one or more paternally expressed genes on chromosome 15 (q11-13). In this study, a comparative analysis of intelligence level and autistic traits was conducted between children with PWS (n = 30; 18 males, 12 females; age = 10.6 ± 2.8 years) and those with Asperger disorder (AD; n = 31; 24 males, 7 females; age = 10.5 ± 3.1 years). The children were compared by age group: lower elementary school age (6-8 years), upper elementary school age (9-12 years), and middle school age (13-15 years). As results, the intelligence levels of children with PWS were significantly lower than those with AD across all age groups. Autistic traits, assessed using the Pervasive Developmental Disorders Autism Society Japan Rating Scale (PARS), revealed that among elementary school age children, those with PWS had less prominent autistic traits than those with AD, however, among middle school age children, those with PWS and AD showed similar prominence. An analysis of the PARS subscale scores by age group showed that while the profiles of autistic traits for children with PWS differed from those of children with AD at elementary school age, the profiles showed no significant differences between the groups at middle school age. The findings suggest that autistic traits in PWS become gradually more prominent with increasing of age and that these autistic traits differ in their fundamental nature from those observed in AD. © 2014 Wiley Periodicals, Inc.

Autism spectrum disorder (ASD) is a perplexing and pervasive developmental disorder characterized by social difficulties, communicative deficits, and repetitive behavior. The increased rate of ASD diagnosis has raised questions concerning the genetic and environmental factors contributing to the development of this disorder; meanwhile, the cause of ASD remains unknown. This study surveyed mothers of ASD and non-ASD children to determine possible effects of labor and delivery (L&D) drugs on the development of ASD. The survey was administered to mothers; however, the results were analyzed by child, as the study focused on the development of autism. Furthermore, an independent ASD dataset from the Southwest Autism Research and Resource Center was analyzed and compared. Indeed, L&D drugs are associated with ASD (p = .039). Moreover, the Southwest Autism Research and Resource Center dataset shows that the labor induction drug, Pitocin, is significantly associated with ASD (p = .004). We also observed a synergistic effect between administrations of L&D drugs and experiencing a birth complication, in which both obstetrics factors occurring together increased the likelihood of the fetus developing ASD later in life (p = .0003). The present study shows the possible effects of L&D drugs, such as Pitocin labor-inducing and analgesic drugs, on children and ASD. © The Author(s) 2016.

Autism spectrum disorders (ASDs) are a group of complex pervasive developmental disorders characterized by impairments in communication, social interaction and behavior. In most cases autism is caused by a combination of genetic factors and environmental risk factors. In 10% to 20% of cases it has been shown that the cause of ASD is genetic. We are describing a 2-year-old boy who was referred to genetic counseling because of speech delay and certain autism-like behavior. By cytogenetic analysis the karyotype 46, inv(X),Y was obtained. The boy was a carrier of a paracentric inversion of the short arm of the chromosome X. After cytogenetic analysis of parental blood, it was detected that mother was a carrier of identical aberration, but had no clinical signs. The method of fluorescent in situ hybridization (FISH) yielded the precise breakpoint in the region (p21.2p11.23). Mother and son were carriers of identical X chromosome. Breakpoints are located in the regions that have already been linked to autism, which indicates that the positional effect of the gene could have been a possible cause of the patient's genotype. In addition to positional effects, in order to better understand the etiology of autism other genetic and environmental factors should be always taken into consideration.

Background: Nuclear distribution E homolog 1 (NDE1), located within chromosome 16p13.11, plays an essential role in microtubule organization, mitosis, and neuronal migration and has been suggested by several studies of rare copy number variants to be a promising schizophrenia (SCZ) candidate gene. Recently, increasing attention has been paid to rare single-nucleotide variants (SNVs) discovered by deep sequencing of candidate genes, because such SNVs may have large effect sizes and their functional analysis may clarify etiopathology. Methods and Results: We conducted mutation screening of NDE1 coding exons using 433 SCZ and 145 pervasive developmental disorders samples in order to identify rare single nucleotide variants with a minor allele frequency ≤5%. We then performed genetic association analysis using a large number of unrelated individuals (3554 SCZ, 1041 bipolar disorder [BD], and 4746 controls). Among the discovered novel rare variants, we detected significant associations between SCZ and S214F (P = .039), and between BD and R234C (P = .032). Furthermore, functional assays showed that S214F affected axonal outgrowth and the interaction between NDE1 and YWHAE (14-3-3 epsilon; a neurodevelopmental regulator). Conclusions: This study strengthens the evidence for association between rare variants within NDE1 and SCZ, and may shed light into the molecular mechanisms underlying this severe psychiatric disorder.

Seizure disorder and developmental disorder are two of the most common chronic disorders in childhood. Data on perceived parental burden and specific effects on daily life is scarce. We performed a structured interview, consecutively talking to all parents of pediatric outpatients of our university hospital diagnosed with seizure or developmental disorder. Three hundred seven parents (of 317 affected children: 53 with seizure disorder, 44 with specific developmental disorder, 35 with learning disorder, 71 with intellectual disability, 15 with seizure + specific developmental disorder, 23 with seizure + learning disorder, 76 with seizure disorder + intellectual disability) were interviewed. Parents of children with both seizure disorder and intellectual disability stated the highest constraints in daily life, regarding friends, hobbies, emotional pressure, occupation, partnership, habitation, and financial burden. Due to diagnosis of seizure or developmental disorder, 155/307 (51%) parents reduced their working hours/stopped working, 62/307 (20%) changed their habitation, and 46/307 (15%) broke up. As judged by parents, 148/317 (47%) children are being discriminated against, even own family/friends and educators are held responsible. Parents perceive changes in their daily life and discrimination of their children due to their children's seizure and developmental disorders. An intellectual disability combined with seizure disorder caused the highest constraint. What is Known: • Seizure and/or developmental disorders of children may adversely influence quality of life for affected parents. • Caring for a child with special health care needs can take complete attention and own parental needs may therefore be difficult to meet. What is New: • Two out of three parents stated changes of their daily life such as quitting work, change of habitation, or breakup of partnership due to their child's diagnosis. • As judged by the parents, one in two children with developmental disorder of any kind is being discriminated against, even teachers and own family are held responsible.

Abstract Background Second-generation antipsychotics (SGAs) are associated with weight gain, metabolic abnormalities, sedation/sleep disturbance, and prolactin abnormalities, especially in youths. Although stimulants have opposing dopamine receptor and adverse effects, it is unclear whether stimulant co-treatment counteracts the therapeutic or side effects of antipsychotics. Methods This was a naturalistic cohort study including 153 antipsychotic trials in youths aged 4–19 (mean, 11.3 ± 3.0) years, started on an SGA for clinically significant aggression or oppositionality associated with oppositional defiant disorder, conduct disorder, disruptive behavior disorder not otherwise specified (NOS), impulse control disorder NOS, intermittent explosive disorder, Tourette's disorder, autistic disorder, and pervasive developmental disorder NOS. Patients underwent fasting assessments of body composition, lipids, glucose, insulin, prolactin, sedation, and general efficacy at baseline, weeks 4, 8, and 12, comparing patients co-prescribed stimulants (n = 71) with those not co-prescribed stimulants (n = 82). Results Patients received risperidone (33.3%), aripiprazole (29.4%), quetiapine (18.4%), olanzapine (11.8%), ziprasidone (5.9%), or clozapine (0.7%). With and without adjustment for differences in baseline variables (sex, prior stimulant use, primary Diagnostic and Statistical Manual of Mental Disorders, 4th edition [DSM-IV] disorders, co-morbid attention-deficit/hyperactivity disorder [ADHD], present in 46.3% of youths not receiving stimulants, and some body composition parameters), patients on versus off stimulants did not differ on any of the assessed outcomes (all p values ≥ 0.1). Conclusions In contrast to guidelines, stimulant use did not precede or accompany antipsychotic use during the current episode of aggression/oppositionality in almost half of those youths who had aggressive/oppositional behavior and a DSM-IV diagnosis of ADHD. At the clinically prescribed doses, stimulant co-treatment of SGAs did not seem to significantly reduce antipsychotic effects on body composition, metabolic parameters, prolactin, sedation, and broad efficacy.

Parental criminal offending is an established risk factor for offending among offspring, but little evidence is available indicating the impact of offending on early childhood functioning. We used data from a large Australian population cohort to determine associations between exposure to parental offending and a range of developmental outcomes at age 5 years. Multi-generation data in 66 477 children and their parents from the New South Wales Child Development Study were combined using data linkage. Logistic and multinomial regressions tested associations between any and violent offending histories of parents (fathers, mothers, or both parents) obtained from official records, and multiple measures of early childhood developmental functioning (social, emotional-behavioural, cognitive, communication and physical domains) obtained from the teacher-reported 2009 Australian Early Development Census. Parental offending conferred significantly increased risk of vulnerability on all domains, particularly the cognitive domain. Greater risk magnitudes were observed for offending by both parents and by mothers than by fathers, and for violent than for any offending. For all parental offending exposures, vulnerability on multiple domains (where medium to large effects were observed) was more likely than on a single domain (small to medium effects). Relationships remained significant and of comparable magnitude following adjustment for sociodemographic covariates. The effect of parental offending on early childhood developmental outcomes is pervasive, with the strongest effects on functioning apparent when both parents engage in violent offending. Supporting affected families in early childhood might mitigate both early developmental vulnerability and the propensity for later delinquency among these offspring.

Time perspective is a fundamental dimension of the psychological time construct, with a pervasive and powerful influence on human behavior. However, the developmental trajectory of time perspective across a human lifespan remains unclear. The current study aimed to portray the developmental trajectory of all dimensions of time perspectives from children to older adults in a large sample. A total of 1,901 individuals (aged 9-84 years) completed measures of time perspective. They were then divided into five age groups: children, teenagers, young adults, middle-aged adults, and older adults. Results suggested that each time perspective showed a unique developmental pattern across the lifespan. Moreover, perceived economic situation and education were related to some dimensions of time perspective. © 2016 The Institute of Psychology, Chinese Academy of Sciences and John Wiley & Sons Australia, Ltd.

The prevalence of autism spectrum disorders (ASD) has increased 10-fold in recent years. We have assessed the prevalence of high functioning autism spectrum disorders in a clinical sample in a Norwegian county. Medical records from the health specialist services were assessed for children (0-18 years of age) with a diagnosis of Asperger syndrome or pervasive developmental disorder not otherwise specified (PDD-NOS) in South Trøndelag county at two time-points (1.1.2005 and 1.1.2008). We also estimated the prevalence of high functioning children with autism (HFA) 1.1.2008. The number of children and adolescents with the diagnosis Asperger syndrome increased from 70 in 2005 to 121 in 2008 and that for children with PDD-NOS increased from 22 to 44 in the same period. In the child mental health service, the number of patients with Asperger syndrome increased from 51 in 2005 to 99 in 2008 and in the habilitation services there were 32 such patients in both years assessed. Some patients were registered in both services: 13 in 2005 and 10 in 2008. In 2008, the prevalence of all high functioning autism spectrum disorders together was 0.35 % of the population in the age 5-18 years. Almost none of the children were below 5 years at the time of assessment. In South Trøndelag the prevalence of children with high functioning autism spectrum disorders are in the same size order as that reported from international surveys. This can be explained by increased awareness on such disorders and that more able people are diagnosed. The difference in prevalence between the health services reflects different diagnostic traditions and changed referral routines.

Assessing Autism-like Behavior in Mice: Variations in Social Interactions Among Inbred Strains.

Autism is a pervasive developmental disorder, with characteristics including impairments in reciprocal social interaction, impaired communication, and repetitive/stereotyped behaviors. Despite decades of research, the etiology of autism remains elusive. Thus, it is important that we pursue all avenues, in attempting to understand this complicated disorder. One such avenue is the development of animal models. While autism may be uniquely human, there are behavioral characteristics of the disorder that can be established in animal models. Evidence supports a genetic component for this disorder, and over the past few decades the mouse has been a highly valuable tool for the elucidation of pathways involved in many human disorders (e.g., Huntington’s disease). As a first step toward establishing a mouse model of autism, we studied same-sex social behavior in a number of inbred mouse strains. In Study 1, we examined intra-strain social behavior of male pairs after one mouse had 15 minutes prior exposure to the testing chamber. In Study 2, we evaluated intra-strain and inter-strain social behavior when both mice were naive to the testing chamber. The amount and type of social behavior seen differed between these studies, but overall there were general inbred strain differences in social behavior. Some strains were highly social (e.g., FVB/NJ, while others displayed low levels of social behavior (e.g., A/J, BTBR T+ tf/J). These strains may be useful in future genetic studies to determine specific genes involved in mouse social behavior, the findings of which should in turn help us to determine some of the genes involved in human social behavior and its disorders (e.g., autism).

To review the diagnostic criteria for autism spectrum disorder (ASD) from the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-V), and to develop an approach to managing ASD using the CanMEDS- Family Medicine (CanMEDS-FM) framework. The DSM-V from the American Psychiatric Association, published in May 2013, provides new diagnostic criteria for ASD. The College of Family Physicians of Canada's CanMEDS-FM framework provides a blueprint that can guide the complex management of ASD. We used data from the Centers for Disease Control and Prevention to determine the prevalence of ASD, and we used the comprehensive systematic review and meta-analysis completed by the UK National Institute for Health and Care Excellence for their guidelines on ASD to assess the evidence for more than 100 interventions. The prevalence of ASD was 1 in 88 in 2008 in the United States according to data from the Centers for Disease Control and Prevention. The ASD classification in the fourth edition of the DSM included autism, Asperger syndrome, pervasive developmental disorder, and childhood disintegrative disorder. The new DSM-V revision incorporates all these disorders into one ASD umbrella term with different severity levels. The management of ASD is complex and requires a multidisciplinary team effort and continuity of care. The CanMEDS-FM roles provide a framework for management. Family physicians are the key leaders of the multidisciplinary care team for ASD, and the CanMEDS-FM framework provides a comprehensive guide to help manage a child with ASD and to help the child's family.

Background A subgroup of persons with anorexia nervosa (AN) have been proposed to have sociocommunicative problems corresponding to autism spectrum disorders [ASDs, i.e. DSM-IV pervasive developmental disorders (PDDs): autistic disorder, Asperger's disorder, PDD not otherwise specified (NOS)]. Here, clinical problems, personality traits, cognitive test results and outcome are compared across 16 subjects (32%) with teenage-onset AN who meet or have met ASD criteria (AN+ASD), 34 ASD-negative AN subjects and matched controls from a longitudinal Swedish study including four waves of independent assessments from the teens to the early thirties. Method The fourth wave included the Structured Clinical Interview for DSM-IV (SCID)-I and the SCID-II (cluster C, i.e. ‘anxious’ PDs) interviews, the Asperger Syndrome Diagnostic Interview, self-assessments by the Autism Spectrum Quotient and the Temperament and Character Inventory, neurocognitive tests by subscales from the Wechsler scales, continuous performance tests, Tower of London, and Happé's cartoons. Results The ASD assessments had substantial inter-rater reliability over time (Cohen's κ between 0.70 and 0.80 with previous assessments), even if only six subjects had been assigned a diagnosis of an ASD in all four waves of the study, including retrospective assessments of pre-AN neurodevelopmental problems. The AN+ASD group had the highest prevalence of personality disorders and the lowest Morgan–Russell scores. The non-ASD AN group also differed significantly from controls on personality traits related to poor interpersonal functioning and on neurocognitive tests. Conclusions A subgroup of subjects with AN meet criteria for ASDs. They may represent the extreme of neurocognitive and personality problems to be found more generally in AN. PMID:22186945

Social communication disorder outside autism? A diagnostic classification approach to delineating pragmatic language impairment, high functioning autism and specific language impairment.

Developmental disorders of language and communication present considerable diagnostic challenges due to overlapping of symptomatology and uncertain aetiology. We aimed to further elucidate the behavioural and linguistic profile associated with impairments of social communication occurring outside of an autism diagnosis. Six to eleven year olds diagnosed with pragmatic language impairment (PLI), high functioning autism (HFA) or specific language impairment (SLI) were compared on measures of social interaction with peers (PI), restricted and repetitive behaviours/interests (RRBIs) and language ability. Odds ratios (OR) from a multinomial logistic regression were used to determine the importance of each measure to diagnostic grouping. MANOVA was used to investigate differences in subscale scores for the PI measure. Greater degrees of PI difficulties (OR = 1.22, 95% CI = 1.05-1.41), RRBI (OR = 1.23, 95% CI = 1.06-1.42) and expressive language ability (OR = 1.16, 95% CI = 1.03-1.30) discriminated HFA from PLI. PLI was differentiated from SLI by elevated PI difficulties (OR = 0.82, 95% CI = 0.70-0.96) and higher expressive language ability (OR = 0.88, 95% CI = 0.77-0.98), but indistinguishable from SLI using RRBI (OR = 1.01, 95% CI=0.94-1.09). A significant effect of group on PI subscales was observed (θ = 1.38, F(4, 56) = 19.26, p < .01) and PLI and HFA groups shared a similar PI subscale profile. Results provide empirical support for a conceptualisation of PLI as a developmental impairment distinguishable from HFA by absence of RRBIs and by the presence of expressive language difficulties. PI difficulties appear elevated in PLI compared with SLI, but may be less pervasive than in HFA. Findings are discussed with reference to the proposed new category of 'social communication disorder' in DSM-5. © 2013 The Authors Journal of Child Psychology and Psychiatry © 2013 Association for Child and Adolescent Mental Health.

Autism, oxytocin and interoception

PubMed Central

Quattrocki, E.; Friston, Karl

2014-01-01

Autism is a pervasive developmental disorder characterized by profound social and verbal communication deficits, stereotypical motor behaviors, restricted interests, and cognitive abnormalities. Autism affects approximately 1% of children in developing countries. Given this prevalence, identifying risk factors and therapeutic interventions are pressing objectives—objectives that rest on neurobiologically grounded and psychologically informed theories about the underlying pathophysiology. In this article, we review the evidence that autism could result from a dysfunctional oxytocin system early in life. As a mediator of successful procreation, not only in the reproductive system, but also in the brain, oxytocin plays a crucial role in sculpting socio-sexual behavior. Formulated within a (Bayesian) predictive coding framework, we propose that oxytocin encodes the saliency or precision of interoceptive signals and enables the neuronal plasticity necessary for acquiring a generative model of the emotional and social ‘self.’ An aberrant oxytocin system in infancy could therefore help explain the marked deficits in language and social communication – as well as the sensory, autonomic, motor, behavioral, and cognitive abnormalities – seen in autism.

A macroepigenetic approach to identify factors responsible for the autism epidemic in the United States

PubMed Central

2012-01-01

The number of children ages 6 to 21 in the United States receiving special education services under the autism disability category increased 91% between 2005 to 2010 while the number of children receiving special education services overall declined by 5%. The demand for special education services continues to rise in disability categories associated with pervasive developmental disorders. Neurodevelopment can be adversely impacted when gene expression is altered by dietary transcription factors, such as zinc insufficiency or deficiency, or by exposure to toxic substances found in our environment, such as mercury or organophosphate pesticides. Gene expression patterns differ geographically between populations and within populations. Gene variants of paraoxonase-1 are associated with autism in North America, but not in Italy, indicating regional specificity in gene-environment interactions. In the current review, we utilize a novel macroepigenetic approach to compare variations in diet and toxic substance exposure between these two geographical populations to determine the likely factors responsible for the autism epidemic in the United States.

Mothers of young children with Pervasive Developmental Disorders (PDD) and other disabilities (DD) have been reported to experience high levels of stress. This investigation examined the effects of parental stress on mothers' participation in a Relationship Focused intervention (RFI). Mothers and young children who had either PDD (n = 18) or DD (n = 26) received weekly RF intervention for one year. Pre-post comparisons indicated significant increases in mothers' responsiveness and children's development and social emotional functioning. Intervention effects were greater for mothers of children with PDD than for mothers of children with DD. There were three findings related to the role parenting stress. First, high levels of parenting stress did not interfere with mothers' ability to learn RFI strategies; second, there were non-significant decreases in parenting stress during intervention; third, parenting stress enhanced the effects of mothers' responsiveness on children. High levels of parenting stress does not appear to interfere with parent participation in RFI. © 2015 John Wiley & Sons Ltd.

Although sense of coherence (SOC) moderates parental stress, the relationship between SOC, parental mental health and physical punishment of children with intellectual disabilities remains uncertain. The present authors describe parental physical punishment towards children with intellectual disabilities and investigate its related demographic characteristics, SOC and parental mental health. With the cooperation of Tokyo's 10 special needs schools, the present authors obtained 648 questionnaire responses from parents of children with intellectual disabilities. Of the parents, 69.7% reported having physically punished their children with intellectual disabilities. This was positively associated with parents' younger age, poorer mental health, lower SOC, children's younger age, birth order (firstborns) and disability type (autism/pervasive developmental disorder). This is the first study supporting the relationship between SOC, mental health and physical punishment use among parents of children with intellectual disabilities. It may assist the development of strategies to prevent physical abuse of children with disabilities. © 2015 John Wiley & Sons Ltd.

The handicapped child: psychological effects of parental, marital, and sibling relationships.

PubMed

Fisman, S; Wolf, L

1991-03-01

Although the nature and severity of a handicapping condition are not the sole determinants of family functioning, the presence of a child with a pervasive developmental disorder has a significant effect on family members. Maternal mental health suffers, and the resulting depression affects her role as mother and marriage partner. Unlike other handicapping conditions with obvious physical stigmata, the invisible handicap of the autistic child and the frequent delay in diagnosis contribute to the mother's self-doubt about her parental competence. While the impact on paternal psychological health is less, the fathers of autistic children are nevertheless highly stressed and appear to be particularly vulnerable to the stress generated by these difficult children. Living within this family climate, the risks for emotional and behavioral problems for siblings must be evaluated, along with their intrinsic strengths, to plan preventive interventions for these children. Effective work with these families requires an understanding of the evolution of family system problems and their dynamic and reciprocal interaction over time.

Theoretical aspects of autism: causes--a review.

PubMed

Ratajczak, Helen V

2011-01-01

Autism, a member of the pervasive developmental disorders (PDDs), has been increasing dramatically since its description by Leo Kanner in 1943. First estimated to occur in 4 to 5 per 10,000 children, the incidence of autism is now 1 per 110 in the United States, and 1 per 64 in the United Kingdom, with similar incidences throughout the world. Searching information from 1943 to the present in PubMed and Ovid Medline databases, this review summarizes results that correlate the timing of changes in incidence with environmental changes. Autism could result from more than one cause, with different manifestations in different individuals that share common symptoms. Documented causes of autism include genetic mutations and/or deletions, viral infections, and encephalitis following vaccination. Therefore, autism is the result of genetic defects and/or inflammation of the brain. The inflammation could be caused by a defective placenta, immature blood-brain barrier, the immune response of the mother to infection while pregnant, a premature birth, encephalitis in the child after birth, or a toxic environment.

Few longitudinal studies have explored lifetime criminality in adults with a childhood history of severe mental disorders. In the present study, we wanted to explore the association between adult delinquency and several different childhood diagnoses in an in-patient population. Of special interest was the impact of disturbance of activity and attention (ADHD) and mixed disorder of conduct and emotions on later delinquency, as these disorders have been variously associated with delinquent development. Former Norwegian child psychiatric in-patients (n = 541) were followed up 19-41 years after hospitalization by record linkage to the National Register of Criminality. On the basis of the hospital records, the patients were re-diagnosed according to ICD-10. The association between diagnoses and other baseline factors and later delinquency were investigated using univariate and multivariate Cox regression analyses. At follow-up, 24% of the participants had been convicted of criminal activity. In the multivariate Cox regression analysis, conduct disorder (RR = 2.0, 95%CI = 1.2-3.4) and hyperkinetic conduct disorder (RR = 2.7, 95% CI = 1.6-4.4) significantly increased the risk of future criminal behaviour. Pervasive developmental disorder (RR = 0.4, 95%CI = 0.2-0.9) and mental retardation (RR = 0.4, 95%CI = 0.3-0.8) reduced the risk for a criminal act. Male gender (RR = 3.6, 95%CI = 2.1-6.1) and chronic family difficulties (RR = 1.3, 95% CI = 1.1-1.5) both predicted future criminality. Conduct disorder in childhood was highly associated with later delinquency both alone or in combination with hyperactivity, but less associated when combined with an emotional disorder. ADHD in childhood was no more associated with later delinquency than the rest of the disorders in the study population. Our finding strengthens the assumption that there is no direct association between ADHD and criminality.

The association between diagnoses and other baseline factors and later delinquency were investigated using univariate and multivariate Cox regression analyses. Results At follow-up, 24% of the participants had been convicted of criminal activity. In the multivariate Cox regression analysis, conduct disorder (RR = 2.0, 95%CI = 1.2-3.4) and hyperkinetic conduct disorder (RR = 2.7, 95% CI = 1.6-4.4) significantly increased the risk of future criminal behaviour. Pervasive developmental disorder (RR = 0.4, 95%CI = 0.2-0.9) and mental retardation (RR = 0.4, 95%CI = 0.3-0.8) reduced the risk for a criminal act. Male gender (RR = 3.6, 95%CI = 2.1-6.1) and chronic family difficulties (RR = 1.3, 95% CI = 1.1-1.5) both predicted future criminality. Conclusions Conduct disorder in childhood was highly associated with later delinquency both alone or in combination with hyperactivity, but less associated when combined with an emotional disorder. ADHD in childhood was no more associated with later delinquency than the rest of the disorders in the study population. Our finding strengthens the assumption that there is no direct association between ADHD and criminality. PMID:21481227

Autism is a pervasive developmental disorder of childhood characterised by disturbances in both social interactions and communication as well as stereotyped patterns of activities and behaviour. The increase in estimates of the prevalence of autism has raised the question of an "epidemic" of autism. More active case assessment and changes in diagnostic criteria probably account in large part for such increase. Investigators have attempted to define the neural pathophysiology of autism ever since the hypothesis of "refrigerator mother" as its cause was replaced by the view that it is a developmental disorder of the immature brain. However consensus is yet to be reached concerning the brain regions implicated. Psychoanalysis, cognitive psychology, neurophysiology, neuropharmacology, and genetics propose restricted view of the major issues leaving extensive areas unexplored. Therapeutic approaches induce only partial and uncertain results. There is no cure for autism but substantial evidence indicates that early, intensive, individualised education is beneficial for children. All modern intervention programs for autism affected children share a high degree of environmental structuring and predictability and an extensive individual approach. Autism being a behaviourally defined syndrome, it gave rise to a number of controversies concerning definition, classification, etiopathogenesis and therapeutics. In the 1990s a crisis has occurred in France with a loss of confidence between parents and psychiatrists with a problem concerning the means and ways of care of the autistic individual. The aim of this paper is to point out the different questions raised by autism in order to better understand this syndrome which touches upon essential behaviour-related aspects such as self consciousness, reality perception, the functioning of the thought and communication, as well as the role of hereditary and acquired influences in normal and pathological development.

2014-02-01

This study examines whether parents of children with developmental disorders are at risk of elevated allostatic load relative to control parents and whether positive affect moderates difference in risk. In all, 38 parents of children with developmental disorders and 38 matched comparison parents were analyzed. Regression analyses revealed a significant interaction between parent status and positive affect: parents of children with developmental disorders had lower allostatic load when they had higher positive affect, whereas no such association was evident for comparison parents. The findings suggest that promoting greater positive affect may lower health risks among parents of children with developmental disorders.

Developmental variations in the impact of intimate partner violence exposure during childhood

Abstract: Background: Intimate partner violence (IPV) is a pervasive problem impacting individuals around the globe. The consequences of IPV extend beyond the adults in the relationship, as children witness a significant proportion of such violence. Exposure to IPV during childhood has devastating effects across multiple domains of functioning. Methods: This article reviews empirical studies of the effects of exposure to IPV by developmental stage. Results: The psychological, social, physical, and cognitive consequences of witnessing IPV are examined across development; from the impact of prenatal exposure to effects in infancy and toddlerhood, the preschool years, school-aged children, and adolescence. Conclusions: The review concludes by providing suggestions for future research based on the identified developmental variations, recommendations for developmentally-sensitive interventions for children who have witnessed IPV, and directions for policy to address the issue of violence exposure early in the lives of children.

The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) was published in May 2013. Autism spectrum disorder (ASD) has been structured for the three subtypes of pervasive developmental disorder (PDD), but the number of impairment in social and communication dimension is not stated. The subjects were 68 children who visited the Department of Psychology and Development at Nagoya City University Hospital for the first time between the ages of 6 and 15 years old. We retrospectively re-examined the subjects using DSM-IV-TR criteria and DSM-5 criteria with two rules (two of three and one of three on the social and communication dimension) and examined the concordance rate. Forty subjects were diagnosed with PDD, and 28 were not. The mean PDD subject age was 9.4 years, and mean IQ was 84.0 on the Wechsler Intelligence Scale for Children III or 62.7 on the Tanaka-Binet test. Twenty-seven (68%) of the PDD subjects were classified with ASD using DSM-5 criteria when the two of three rule was applied, while 32 (80%) were classified with ASD when the one of three rule was applied. All subjects without PDD were not diagnosed with ASD on DSM-5 criteria. DSM-5 criteria may exclude high functioning and older subjects from ASD because they tend to be atypical. The diagnostic procedure for DSM-5 criteria is ambiguous, especially in high functioning subjects and those diagnosed at an older age. © 2015 Japan Pediatric Society.

Features of attention deficit hyperactivity disorder (ADHD) and impairments on neuropsychological, tests of attention have been documented in children with autism spectrum disorders (ASDs). To date, there has been a lack of research comparing attention in adults with ASD and adults with ADHD. In study 1, 31 adults with ASD and average intellectual function completed self-report measures of ADHD symptoms. These were compared with self-report measures of ADHD symptoms in 38 adults with ADHD and 29 general population controls. In study 2, 28 adults with a diagnosis of ASD were compared with an age- and intelligence quotient-matched sample of 28 adults with ADHD across a range of measures of attention. Study 1 showed that 36.7% of adults with ASD met Diagnostic and Statistical Manual-IV criteria for current ADHD "caseness" (Barkley Current self-report scores questionnaire). Those with a diagnosis of pervasive developmental disorder-not otherwise specified were most likely to describe ADHD symptoms. The ASD group differed significantly from both the ADHD and control groups on total and individual symptom self-report scores. On neuropsychological testing, adults with ASD and ADHD showed comparable performance on tests of selective attention. Significant group differences were seen on measures of attentional switching; adults with ADHD were significantly faster and more inaccurate, and individuals with Asperger's syndrome showed a significantly slower and more accurate response style. Self-reported rates of ADHD among adults with ASD are significantly higher than in the general adult population and may be underdiagnosed. Adults with ASD have attentional difficulties on some neuropsychological measures. © 2013 International Society for Autism Research, Wiley Periodicals, Inc.

Autism spectrum disorder (ASD) has both genetic and environmental origins, including potentially maternal effects. Maternal effects describe the association of one or more maternal phenotypes with liability to ASD in progeny that are independent of maternally transmitted risk alleles. While maternal effects could play an important role, consistent with association to maternal traits such as immune status, no study has estimated maternal, additive genetic, and environmental effects in ASD. Using a population-based sample consisting of all children born in Sweden from 1998 to 2007 and their relatives, we fitted statistical models to family data to estimate the variance in ASD liability originating from maternal, additive genetic, and shared environmental effects. We calculated sibling and cousin family recurrence risk ratio as a direct measure of familial, genetic, and environmental risk factors and repeated the calculations on diagnostic subgroups, specifically autistic disorder (AD) and spectrum disorder (SD), which included Asperger's syndrome and/or pervasive developmental disorder not otherwise specified. The sample consisted of 776,212 children of whom 11,231 had a diagnosis of ASD: 4554 with AD, 6677 with SD. We found support for large additive genetic contribution to liability; heritability (95% confidence interval [CI]) was estimated to 84.8% (95% CI: 73.1-87.3) for ASD, 79.6% (95% CI: 61.2-85.1) for AD, and 76.4% (95% CI: 63.0-82.5) for SD. There was modest, if any, contribution of maternal effects to liability for ASD, including subtypes AD and SD, and there was no support for shared environmental effects. These results show liability to ASD arises largely from additive genetic variation. Copyright © 2017 Society of Biological Psychiatry. Published by Elsevier Inc. All rights reserved.

Second generation antipsychotics in Asperger's Disorder and high functioning autism: a systematic review of the literature and effectiveness of meta-analysis.

Sochocky, Natalie; Milin, Robert

2013-11-01

Second generation antipsychotics (SGA) have gained increased evidence for the treatment of irritability and aggression in children and adolescents with lower functioning autistic disorder. Individuals with Asperger's Disorder (AD) and High Functioning Autism (HFA) experience significant emotional and behavioral problems and psychiatric comorbidity. There is a need to review the published literature on SGA treatment efficacy in the AD and HFA populations to provide more effective treatment choices for these subgroups. We conducted a systematic review and meta-analysis of the recent English literature on SGA use in children and adolescents (ages 0-24 years) with AD and HFA using the Medline/PubMed and PsychINFO computerized databases. Key search words were 'Asperger', 'high functioning autism', 'autism spectrum disorders (ASD)', and 'pervasive developmental disorder (PDD)' in combination with 'second generation antipsychotics', 'aripiprazole; 'olanzapine', 'quetiapine', 'risperidone', or 'ziprasidone'. Our search yielded 214 citations, however only open-label or randomized-controlled trials (RCT) with ≥25% of their subjects having an IQ≥71 were included in our review. Eleven original studies met our inclusion parameters for review; eight studies for the meta-analysis. These studies, although limited in methodological rigor, and the meta-analytic results suggest that SGAs provide improvement in behavioral symptoms associated with AD and HFA. The majority of the studies reported weight gain as a potentially concerning adverse effect. There is a lack of robustly conducted trials on the use of SGAs in the management of AD and HFA. More research in pharmacological and psychosocial treatments is warranted. Clinicians are cautioned to approach pharmacological treatment prudently balancing benefit with potential cardiometabolic risk.

Rossignol, Daniel A; Frye, Richard E

2011-09-01

The aim of this study was to investigate melatonin-related findings in autism spectrum disorders (ASD), including autistic disorder, Asperger syndrome, Rett syndrome, and pervasive developmental disorders, not otherwise specified. Comprehensive searches were conducted in the PubMed, Google Scholar, CINAHL, EMBASE, Scopus, and ERIC databases from their inception to October 2010. Two reviewers independently assessed 35 studies that met the inclusion criteria. Of these, meta-analysis was performed on five randomized double-blind, placebo-controlled studies, and the quality of these trials was assessed using the Downs and Black checklist. Nine studies measured melatonin or melatonin metabolites in ASD and all reported at least one abnormality, including an abnormal melatonin circadian rhythm in four studies, below average physiological levels of melatonin and/or melatonin derivates in seven studies, and a positive correlation between these levels and autistic behaviors in four studies. Five studies reported gene abnormalities that could contribute to decreased melatonin production or adversely affect melatonin receptor function in a small percentage of children with ASD. Six studies reported improved daytime behavior with melatonin use. Eighteen studies on melatonin treatment in ASD were identified; these studies reported improvements in sleep duration, sleep onset latency, and night-time awakenings. Five of these studies were randomized double-blind, placebo-controlled crossover studies; two of the studies contained blended samples of children with ASD and other developmental disorders, but only data for children with ASD were used in the meta-analysis. The meta-analysis found significant improvements with large effect sizes in sleep duration (73 min compared with baseline, Hedge's g 1.97 [95% confidence interval {CI} CI 1.10-2.84], Glass's Δ 1.54 [95% CI 0.64-2.44]; 44 min compared with placebo, Hedge's g 1.07 [95% CI 0.49-1.65], Glass's Δ 0.93 [95% CI 0.33-1.53]) and sleep onset latency (66 min compared with baseline, Hedge's g-2.42 [95% CI -1.67 to -3.17], Glass's Δ-2.18 [95% CI -1.58 to -2.76]; 39 min compared with placebo, Hedge's g-2.46 [95% CI -1.96 to -2.98], Glass's Δ-1.28 [95% CI -0.67 to -1.89]) but not in night-time awakenings. The effect size varied significantly across studies but funnel plots did not indicate publication bias. The reported side effects of melatonin were minimal to none. Some studies were affected by limitations, including small sample sizes and variability in the protocols that measured changes in sleep parameters. Melatonin administration in ASD is associated with improved sleep parameters, better daytime behavior, and minimal side effects. Additional studies of melatonin would be helpful to confirm and expand on these findings. © The Authors. Developmental Medicine & Child Neurology © 2011 Mac Keith Press.

Study Objectives: (1) Compare sleep behaviors of children with autism spectrum disorders (ASD) with sleep behaviors of typically developing (TD) children using the Children's Sleep Habits Questionnaire (CSHQ); (2) compare sleep quality—defined as mean activity, sleep latency, number of awakenings, sleep efficiency and total sleep time—of the cohort of children with ASD and TD, as measured by 10 nights of actigraphy; and (3) estimate the prevalence of sleep disturbances in the ASD and TD cohorts. Design: Descriptive cross-sectional study. Setting: The Children's Hospital of Philadelphia. Participants: Randomly selected children from the Regional Autism Center. The ASD cohort of 59 children, aged 4 to 10 years, (26 with autism, 21 with pervasive developmental disorder-not otherwise specified [PDD-NOS], and 12 with Asperger disorder) were compared with 40 TD control subjects. Measurements and Results: The CSHQ, sleep diaries, and 10 nights of actigraphy using the Sadeh algorithm of children with ASD and TD control subjects were compared. CSHQ showed 66.1% of parents of children with ASD (62.5% autism, 76.2% PDD-NOS, 58.3% Asperger disorder) and 45% of parents of the control subjects reported that their children had sleep problems. Actigraphic data showed that 66.7% of children with ASD (75% autism, 52.4% PDD-NOS, 75% Asperger disorder) and 45.9% of the control subjects had disturbed sleep. Conclusions: The prevalence estimate of 45% for mild sleep disturbances in the TD cohort highlights pediatric sleep debt as a public health problem of concern. The prevalence estimate of 66% for moderate sleep disturbances in the ASD cohort underscores the significant sleep problems that the families of these children face. The predominant sleep disorders in the ASD cohort were behavioral insomnia sleep-onset type and insomnia due to PDD.

Sibling Caregivers of People With Intellectual and Developmental Disabilities: Sociodemographic Characteristics and Material Hardship Prevalence.

PubMed

Sonik, Rajan A; Parish, Susan L; Rosenthal, Eliana S

2016-10-01

In growing numbers, people with intellectual and developmental disabilities are outliving their parents, or at least their parents' ability to care for them. Consequently, adult siblings without intellectual and developmental disabilities are increasingly taking on primary caregiving responsibilities. However, adult siblings have received little study generally, and sibling caregivers have received even less. We used nationally representative data from the Survey of Income and Program Participation (SIPP) to describe the social characteristics and material hardship levels of sibling caregivers, in comparison to the general working age adult population. This study finds moderate material hardship to be pervasive among sibling caregivers, though extreme levels of hardship are possibly being abated somewhat through public benefit programs. Implications for greater service needs are discussed.

Autism spectrum disorder (ASD) is a pervasive developmental disorder characterized by deficits in social interaction, language, stereotyped behaviors, and restricted range of interests. In previous studies low frequency repetitive transcranial magnetic stimulation (rTMS) has been used, with positive behavioral and electrophysiological results, for the experimental treatment in ASD. In this study we combined prefrontal rTMS sessions with electroencephalographic (EEG) neurofeedback (NFB) to prolong and reinforce TMS-induced EEG changes. The pilot trial recruited 42 children with ASD (~14.5 years). Outcome measures included behavioral evaluations and reaction time test with event-related potential (ERP) recording. For the main goal of this exploratory study we used rTMS-neurofeedback combination (TMS-NFB, N = 20) and waitlist (WTL, N = 22) groups to examine effects of 18 sessions of integrated rTMS-NFB treatment or wait period) on behavioral responses, stimulus and response-locked ERPs, and other functional and clinical outcomes. The underlying hypothesis was that combined TMS-NFB will improve executive functions in autistic patients as compared to the WTL group. Behavioral and ERP outcomes were collected in pre- and post-treatment tests in both groups. Results of the study supported our hypothesis by demonstration of positive effects of combined TMS-NFB neurotherapy in active treatment group as compared to control WTL group, as the TMS-NFB group showed significant improvements in behavioral and functional outcomes as compared to the WTL group.

2003-10-01

Autism is a heterogeneous pervasive developmental disorder with a poorly defined aetiology and pathophysiology. There are indications that the incidence of the disease is rising but still no definitive diagnostic biochemical markers have been isolated. Here we have addressed the hypothesis that urinary levels of trans -indolyl-3-acryloylglycine (IAG) are abnormal in patients diagnosed with autism spectrum disorders (ASD) compared to age-matched controls. Urine samples were collected on an opportunistic basis and analysed for IAG concentration (normalised against creatinine content to account for changes in urinary volume) using reversed phase HPLC with UV detection. Statistical analysis (Mann-Whitney tests) showed highly significant increases (p=0.0002) in the levels of urinary IAG in the ASD group (median 942 microV per mmol/L of creatinine [interquartile range 521-1729], n=22) compared to asymptomatic controls (331 [163-456], n=18). Detailed retrospective analysis showed that gender (boys 625 microV per mmol/L of creatinine [294-1133], n=29; girls 460 [282-1193], n=11: P=0.79) and age (control donor median 10 years [8-14], n=15; ASD median 9 years [7-11] n=22: P=0.54) were not significantly correlated with IAG levels in this non-blinded volunteer study. Our results strongly suggest that urinary titres of IAG may constitute an objective diagnostic indicator for ASD. Mechanisms for the involvement of IAG in ASD are discussed together with future strategies to address its specificity.

Autism spectrum disorders (ASD) are pervasive developmental disorders characterized by impairments in language development and social interaction, along with restricted and stereotyped behaviors. These behaviors often include atypical responses to sensory stimuli; some children with ASD are easily overwhelmed by sensory stimuli, while others may seem unaware of their environment. Vision and audition are two sensory modalities important for social interactions and language, and are differentially affected in ASD. In the present study, 16 children and adolescents with ASD and 16 typically developing (TD) participants matched for age, gender, nonverbal IQ, and handedness were tested using a mixed event-related/blocked functional magnetic resonance imaging paradigm to examine basic perceptual processes that may form the foundation for later-developing cognitive abilities. Auditory (high or low pitch) and visual conditions (dot located high or low in the display) were presented, and participants indicated whether the stimuli were "high" or "low." Results for the auditory condition showed downregulated activity of the visual cortex in the TD group, but upregulation in the ASD group. This atypical activity in visual cortex was associated with autism symptomatology. These findings suggest atypical crossmodal (auditory-visual) modulation linked to sociocommunicative deficits in ASD, in agreement with the general hypothesis of low-level sensorimotor impairments affecting core symptomatology.

Prevalence and architecture of de novo mutations in developmental disorders.

PubMed

2017-02-23

The genomes of individuals with severe, undiagnosed developmental disorders are enriched in damaging de novo mutations (DNMs) in developmentally important genes. Here we have sequenced the exomes of 4,293 families containing individuals with developmental disorders, and meta-analysed these data with data from another 3,287 individuals with similar disorders. We show that the most important factors influencing the diagnostic yield of DNMs are the sex of the affected individual, the relatedness of their parents, whether close relatives are affected and the parental ages. We identified 94 genes enriched in damaging DNMs, including 14 that previously lacked compelling evidence of involvement in developmental disorders. We have also characterized the phenotypic diversity among these disorders. We estimate that 42% of our cohort carry pathogenic DNMs in coding sequences; approximately half of these DNMs disrupt gene function and the remainder result in altered protein function. We estimate that developmental disorders caused by DNMs have an average prevalence of 1 in 213 to 1 in 448 births, depending on parental age. Given current global demographics, this equates to almost 400,000 children born per year.

Context Multiple studies have reported an overgrowth in head circumference (HC) in the first year of life in autism. However, it is unclear whether this phenomenon is independent of overall body growth and whether it is associated with specific social or cognitive features. Objectives To examine the trajectory of early HC growth in autism compared with control groups; to assess whether HC growth in autism is independent of height and weight growth during infancy; and to examine HC growth from birth to 24 months in relationship to social, verbal, cognitive, and adaptive functioning levels. Design Retrospective study. Setting A specialized university-based clinic. Participants Boys diagnosed as having autistic disorder (n=64), pervasive developmental disorder–not otherwise specified (n=34), global developmental delay (n=13), and other developmental problems (n=18) and typically developing boys (n=55). Main Outcome Measures Age-related changes in HC, height, and weight between birth and age 24 months; measures of social, verbal, and cognitive functioning at age 2 years. Results Compared with typically developing controls, boys with autism were significantly longer by age 4.8 months, had a larger HC by age 9.5 months, and weighed more by age 11.4 months (P=.05 for all). None of the other clinical groups showed a similar overgrowth pattern. Boys with autism who were in the top 10% of overall physical size in infancy exhibited greater severity of social deficits (P=.009) and lower adaptive functioning (P=.03). Conclusions Boys with autism experienced accelerated HC growth in the first year of life. However, this phenomenon reflected a generalized process affecting other morphologic features, including height and weight. The study highlights the importance of studying factors that influence not only neuronal development but also skeletal growth in autism. PMID:21969460

Sleep Problems and Early Developmental Delay: Implications for Early Intervention Programs

ERIC Educational Resources Information Center

Bonuck, Karen; Grant, Roy

2012-01-01

Sleep disorders negatively impact behavior, cognition, and growth--the same areas targeted by early intervention. Conversely, developmental delays and disabilities may themselves precipitate sleep disorders. Young children with developmental delays experience sleep disorders at a higher rate than do typically developing children; the most common…

2016-08-01

Despite initiatives supporting young adults with intellectual and developmental disabilities (IDD) to engage in post-secondary education and integrated employment, those with more intensive support needs are not as easily involved in these post-school experiences. In an effort to learn from positive examples, we examined parent involvement in meaningful post-school experiences by eight young adults with IDD and pervasive support needs. Secondary analysis of data from a prior interview study yielded this smaller sample of eight young adults with meaningful post-school experiences. Their parents were actively involved as fierce advocates and creative problem solvers. The active involvement of parents included: a) attitudinal facilitators, b) advocacy efforts and perceptions, and c) strategic actions. Implications for future research and practice are described.

Developmental and benign movement disorders are a group of movement disorders with onset in the neonatal period, infancy, or childhood. They are characterized by the absence of associated neurological manifestations and by their favorable outcome, although developmental abnormalities can be occasionally observed. Knowledge of the clinical, neurophysiological, and pathogenetic aspects of these disorders is poor. Based on a comprehensive review of the literature and our practical experience, this article summarizes current knowledge in this area. We pay special attention to the recognition and management of these movement disorders in children. (c) 2010 Movement Disorder Society.

This study identifies the outcomes and documents the longitudinal life experiences of adults who attended a specialist residential school for children with pervasive and complex developmental communication impairments. Semistructured interviews were carried out with 26 adult ex-pupils who had attended the school and the parents of 15 of the ex-pupils. Seven key themes were identified from the data, including (a) lack of appropriate support and the impact of this in early childhood, (b) advantages and disadvantages of specialist educational provision compared to mainstream and other provision, (c) changing impact of developmental communication impairments over time, (d) challenging transition away from specialist educational provision, (e) absence of appropriate support for adults with developmental communication impairments, (f) persisting impact of developmental communication impairments on social and emotional functioning in adult life, and (g) differences in perspective between the adult ex-pupils and their parents. Across the adult ex-pupils and their parents, the perceived reported benefits of early intervention, parental support, specialist educational provision, and guidance at times of transitions should inform current service provision for this vulnerable group of individuals and their families.

Some patients with pervasive developmental disorders develop unusual talents, which are characterized as savant syndrome. Herein we present neuropsychological examination and brain imaging (fMRI and brain SPECT) findings of an 18-year-old male with Asperger syndrome and highly unusual calendar memory. Neuropsychological evaluation of the case indicated mild attention, memory, and problem solving deficits, and severe executive function deficits that included conceptualization, category formation, and abstraction. Functional MRI findings showed activation above the baseline level (P<0.05) in the bilateral inferior parietal lobule, precuneus, superior and middle frontal gyri, and medial frontal cortex. Brain SPECT findings, in comparison to rest-SPECT findings, showed that there was hypoperfusion in some brain regions, including the right frontal cortex and right parietal cortex. Baseline blood perfusion in the left frontal cortex was also observed, as well as hypoperfusion in the right parietal-occipital cortex and in the right basal ganglion (compared to the left side). The results of the present study and further research will contribute to our understanding of calendar memory and savant syndrome.

Perspectives on mobile robots as tools for child development and pediatric rehabilitation.

Mobile robots (i.e., robots capable of translational movements) can be designed to become interesting tools for child development studies and pediatric rehabilitation. In this article, the authors present two of their projects that involve mobile robots interacting with children: One is a spherical robot deployed in a variety of contexts, and the other is mobile robots used as pedagogical tools for children with pervasive developmental disorders. Locomotion capability appears to be key in creating meaningful and sustained interactions with children: Intentional and purposeful motion is an implicit appealing factor in obtaining children's attention and engaging them in interaction and learning. Both of these projects started with robotic objectives but are revealed to be rich sources of interdisciplinary collaborations in the field of assistive technology. This article presents perspectives on how mobile robots can be designed to address the requirements of child-robot interactions and studies. The authors also argue that mobile robot technology can be a useful tool in rehabilitation engineering, reaching its full potential through strong collaborations between roboticists and pediatric specialists.

The Origins of Neuroticism.

Barlow, David H; Ellard, Kristen K; Sauer-Zavala, Shannon; Bullis, Jacqueline R; Carl, Jenna R

2014-09-01

In this article, we provide a fresh perspective on the developmental origins of neuroticism--a dimension of temperament marked by elevated stress reactivity resulting in the frequent experience of negative emotions. This negative affectivity is accompanied by a pervasive perception that the world is a dangerous and threatening place, along with beliefs about one's inability to manage or cope with challenging events. Historically, neuroticism has been viewed as a stable, genetically based trait. However, recent understanding of ongoing gene-environment interactions that occur throughout the life span suggests there may be a more complex and dynamic etiology. Thus, the purpose of this article is to offer a theory for understanding the development of neuroticism that integrates genetic, neurobiological, and environmental contributions to this trait. Given the strong correlation between neuroticism and the development of negative health outcomes--most notably, the full range of anxiety and mood disorders--an enhanced understanding of how neuroticism originates has implications for the treatment and prevention of a broad range of pathologies and, perhaps, even for the prevention of neuroticism itself. © The Author(s) 2014.

This study measured gender differences in Prader-Willi syndrome (PWS) in regard to the severity of behavioral symptoms. The Food Related Problem Questionnaire (FRPQ), the Aberrant Behavior Checklist Japanese Version, the Childhood Routines Inventory, the Pervasive Developmental Disorders Autism Society Japan Rating Scale, and Japanese ADHD-RS were administered to PWS patients (45 males aged 6 to 58 and 37 females aged 6 to 45). To examine the effects that gender and genotype have on the severity of each symptom, two-way ANOVAs were conducted. Significant interactions were found only in regard to FRPQ scores, such as FRPQ total score (F(1, 78) = 8.43, p < 0.01). The FRPQ of male deletion (DEL) individuals was higher than that of female DEL and male mUPD. The FRPQ of male maternal uniparental disomy (mUPD) was lower than that of female mUPD. In terms of problem behaviors, routines, autistic behaviors, and hyperactivity, no significant differences were found. Food-related behaviors in DEL were more severe in males, although those in mUPD were less severe in males.
