Does pervasive developmental disorder protect children and adolescents against drug and alcohol use?

Aim The aim of this paper is (1) to compare the rates of reported drug and/or alcohol use (DAU) in treatment seeking adolescents with Pervasive Developmental Disorders (PDD), and those with other psychiatric diagnoses (psychiatric controls) seen in tertiary child and adolescent mental health services and (2) to explore the relationship of psychopathology, environmental stressors, and social communication difficulties to DAU. Method Data from the chart review of children and adolescents aged between 12 and 18 years with psychiatric diagnosis seen in tertiary child and adolescent mental health services between 1992 and 2001 (n=1484) was used to investigate the relationship between DAU, psychopathology, environmental stressors and items related to social communication. Results A total of 97 subjects (7%) met criteria for PDD. Subjects with PDD report significantly lower DAU than psychiatric controls, 3% vs. 17% respectively (P<0.000). Factors reflecting PDD such as speech and language difficulties, developmental difficulties, discordant peer relationships in adolescents are negatively associated with DAU, while conduct problems, affective symptoms, inadequate parental supervision or control have positive association with DAU. DAU was present in PDD only when comorbid with Attention Deficit Hyperactivity Disorder (ADHD). Conclusion Adolescents with speech and language difficulties, developmental difficulties and discordant peer relationships, all reflecting PDD, are less likely to have DAU.     

Pilot evaluation of the Frankfurt Social Skills Training for children and adolescents with autism spectrum disorder

The objective of this pilot study was to evaluate the effectiveness of a group-based intervention aiming at improving social and communication skills in individuals with autism spectrum disorder. Over a period of 11 months, N = 17 children and adolescents received treatment according to the manualised Frankfurt Social Skills Training (KONTAKT). Parent, teacher, expert and blind expert ratings were assessed to judge outcome regarding peer interaction, autistic behaviours, adaptive functioning and family burden. The participants exhibited improvements pre to follow-up treatment, particularly in the area of autistic symptomatology. Effect sizes (partial eta squared) ranged from 0.02 to 0.69. Among other things, regression models showed a positive influence of IQ and language skills on gains in social skills. Findings indicate that KONTAKT might be useful for enhancing social skills and reducing autism-related psychopathology over time in different contexts. Nevertheless, controlled trials are needed to reassure its effectiveness.

Psychosocial issues in a child and adolescent psychiatric clinic population in Nigeria

Abstract Background Psychosocial issues and interventions play a very important role in the aetiology, course and prognosis of several child psychiatric disorders. Psychosocial problems in a child and adolescent psychiatric clinic population in Nigeria were documented as a preliminary step towards the planning and development of this new facility. Methods A standardised assessment procedure was integrated into the routine at the clinic when services commenced. Psychosocial stressors and life events were measured using the interview method so that in–depth information could be obtained. Results Over the 3-year period of study, 79 (62.2%) of the 127 new referrals to the clinic had significant psychosocial stressors in the year preceding presentation. Problems with primary support, such as separation from parents to live with relatives, disruption of the family, abandonment by mother, psychiatric illness in a parent and sexual/physical abuse, occurred in 50 (39.4%) of the subjects. Problems with social environment occurred in 11 (8.7 %), 39 (30.7 %) had educational problems, 5 (3.9%) had economic problems and 15 (11.8%) of the children had other psychosocial stressors. Significantly more children and adolescents with disruptive behaviour disorders and disorders like enuresis, separation anxiety and suicidal behaviour had psychosocial stressors when compared to children with psychotic conditions, autistic disorder and epilepsy (² = 9.6; p = 0.048). Conclusions The importance of the psychosocial diagnostic dimension in routine practice is illustrated in this study. Some psychosocial factors identified are cultural practices. The effects of these practices on child mental health require further study.     

Psychopathology and impairment of quality of life in offspring of psychiatric inpatients in southern Brazil: a preliminary study

Objective

To evaluate the quality of life and risk of psychopathology in the infant and adolescent offspring of psychiatric inpatients from a general hospital unit.

Methods

Offspring (4–17 years old) of psychiatric inpatients were interviewed face-to-face and assessed with the Strengths and Difficulties Questionnaire (SDQ). Interviews with caregivers and the hospitalized parents were also performed. The quality of life of the offspring, psychopathology of their hospitalized parents, and their current caregivers were investigated in order to evaluate any associations between these aspects and psychopathology in the offspring.

Results

Thirty-four children of 25 patients were evaluated, 38.2% of which presented high risk for some type of psychopathology including hyperactivity or attention deficit disorder (38.2%), behavioral disorders (20.6%), and emotional disorders (17.6%). While only the minority of these children (17.6%) were already receiving mental health treatment, another 41.2% of them exhibited some degree of symptoms and were only referred for specialized assessment. Additionally, 61.8% of the children were reported to be suffering from some impairment in their quality of life.

Conclusion

This preliminary study found a high rate of psychopathology in children of psychiatric inpatients. These results corroborate previous evidence that children and adolescents with parents with severe psychopathology are at high risk for developing mental disorders. Public policies and standard protocols of action directed to this population are urgently needed, especially for offspring of parents that are hospitalized in psychiatric in-patient units of general hospitals.

     

Gender dysphoria in pervasive developmental disorders

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.     

Depression in Children with Autism/Pervasive Developmental Disorders: A Case-Control Family History Study

Limited information is available about the occurrence of depression in children with autism and other pervasive developmental disorders (PDD). Although depression has been described in autistic children, questions about its validity have often been raised. One approach to address this issue is to investigate family histories of those autistic children diagnosed with clinical depression. Based on data available in nonautistic children, autistic children with depression would be expected to show an increased family history of depression. Since studies of this nature have not been attempted in autistic children, we compared the family history of 13 autistic/PDD children with depression (11 male; 2 female; M full-scale IQ 86.2, SD 24.2; M age 10.4 years, SD 2.2) with 10 autistic/PDD children without a history of current or previous depression (9 male; 1 female; M full-scale IQ 67, SD 12.9; M age 10.5 years, SD 1.6). Diagnosis of depression was based on the DSM-III-R criteria and confirmed independently by two psychiatrists. Ten (77%) of the depressed children had a positive family history of depression compared to 3 (30%) of the nondepressed group, t(21) = –2.4; p = .02. These findings lend support to the validity of depression as a distinct condition in some children with autism/PDD and suggest that, as in the normal population, autistic children who suffer from depression are more likely to have a family history of depression.     

Pervasive developmental disorders in individuals with cerebral palsy

The aim of the present study was to describe the prevalence and associated factors of pervasive developmental disorders (PDD), including autistic disorder and PDD not otherwise specified (NOS), in a clinical sample of 126 children and adolescents (75 males, 51 females; age range 4–18y, mean 8y 8mo, SD 3y 8mo) with tetraplegic, hemiplegic, diplegic, dyskinetic, or mixed types of cerebral palsy (CP); 28% could not crawl or walk even with support, 29% could move with support, and 43% walked independently. Participants were examined for PDD in two stages. In the first stage, probable participants were determined by direct observation, Autism Behavior Checklist score, and medical reports. In the second stage, those with 'probable' symptoms underwent psychiatric examination and their autistic symptoms were scored on the Childhood Autism Rating Scale. The final diagnosis of autistic disorder or PDD-NOS was given according to DSM-IV criteria. Fourteen (11%) and five (4%) of the participants met the criteria for autistic disorder and PDD-NOS respectively. Children with CP and PDD differed from those without PDD in terms of type of CP ( p =0.02), presence of epilepsy ( p <0.001), intellectual level ( p <0.001), and level of speech ( p <0.001). PDD was more common in children with tetraplegic, mixed, and hemiplegic CP, and in children with epilepsy, learning disability, * and low level of speech. The findings corroborate the notion that CP is a complex disorder, often associated with additional impairments. PDD is not rare in CP and should be considered in patients with comorbid conditions such as epilepsy, learning disability, and language delay and in the presence of tetraplegic, mixed, and hemiplegic CP types.     

Attention deficit hyperactivity disorder symptoms in pervasive developmental disorders: association with autistic behavior domains and coexisting psychopathology

BACKGROUND: Symptoms as in attention deficit hyperactivity disorder (ADHD) are frequent among individuals with pervasive developmental disorders (PDD). The aim of the present study was to examine the impact of inattention, hyperactivity and impulsivity on the clinical phenotype of children and adolescents with PDD. SAMPLING AND METHODS: A total of 182 subjects (41 females) diagnosed as having PDD were split into a high (PDD+) and a lower (PDD) attention problem group using the median of the Child Behavior Checklist (CBCL) syndrome scale 'attention problems' (median T score = 75). The groups were compared with regard to the degree of coexisting psychopathology, as measured by the remaining 7 CBCL subscales, and autistic core features assessed by the Autism Diagnostic Interview-Revised (ADI-R) and the Autism Diagnostic Observation Schedule using a multivariate analysis of covariance adjusted for age, IQ and socioeconomic status. RESULTS: The PDD+ subjects exhibited a significantly higher degree of general psychopathology than the subjects in the PDD subgroup, regarding both internalizing and externalizing symptoms. In addition, the PDD+ subgroup tended to exhibit more impairments on the social interaction scale of the ADI-R. CONCLUSIONS: Clinicians should adjust treatment plans to ensure comprehensive and effective treatment for both PDD and associated ADHD. A dual diagnosis may be essential to the implementation of effective treatments.     

Les obsessions et les compulsions retrouvées dans l’autisme: Étude comparative entre des enfants autistes et des enfants trisomiques 21 à l’école spécialisée pour handicap Sesobel au Liban

Purpose

The purpose of this study is to examine the types of thoughts and repetitive behavior manifested by children and adolescents who suffer autistic disorders, and to compare their prevalence to children and adolescents suffering from Down syndrome.

Method

Twenty six patients, for whom their educator had completed the list of symptoms of the Yale Brown Obsessive Compulsive Scale (Y-BOCS SCL), were admitted at Sesobel (a specialized school for the handicapped in Lebanon) with the diagnosis of autistic disorder (DSM-IV). The current or common types of obsessions and compulsions were evaluated. The witness group consisted of thirty persons suffering from Down syndrome with matching age and sex.

Results

The Anova test showed that the prevalence of global thoughts and repetitive behavior was significantly higher in the autistic group than in the Down syndrome group. The obsessions related to fear of self-inflicted suffering, the obsessions of contamination, the compulsions of order, of tidying up, and the need to touch, happened significantly more frequently in the autistic group, while in the witness group no types of obsession or compulsion were noted.

Conclusion

These results suggest that there autistic children and adolescents have a higher level of varied thoughts and of repetitive behaviors than children and adolescents suffering from Down syndrome.     

Sleep–Wake Patterns Reported by Parents in Hyperactive Children Diagnosed According to ICD-10, as Compared to Paired Controls

This study aimed primarily to compare the parent-reported sleep of children with ICD-10 hyperkinetic disorder (HKD) versus community children. Thirty children aged 5–13 years (83.3 % boys) diagnosed with HKD by their child and adolescent psychiatrists took part in this study, plus 30 community children, matched for sex, age, and school year. Compared to the controls, the HKD children showed significantly later bedtimes, stronger bedtime resistance, longer sleep latency, shorter sleep; more frequent behaviors and symptoms concerning falling asleep into parents bed, needing something special to initiate sleep, nightmares, sleep talking, sleep bruxism, fear from darkness, bedwetting, and, most notably, loud snoring (26.7 %); they also tended to show higher daytime somnolence. Attention deficit/hyperactivity disorder (ADHD)/HKD children may thus have more sleep-related problems than typically developing children. Alternatively, our results may reflect misdiagnoses; thus, special attention should be directed to comorbidity and differential diagnosis issues between sleep disturbances and ADHD/HKD.     

Do hyperactivity,impulsivity and inattention have an impact on the ability of facial affect recognition in children with autism and ADHD?

Psychopathological, genetic and neuropsychological findings indicate an association between autism and attention deficit/hyperactivity disorder (ADHD). The goal of this study was to assess possible differences in facial affect recognition in children with autism (with and without comorbid ADHD), with ADHD and healthy controls. Children aged 6–18 years old with DSM-IV-diagnosis ADHD (n = 30) or autism (n = 40) were included consecutively in the study. Facial affect recognition was assessed with a computer-based program used for teaching emotion processing called the Frankfurt Test and Training of Social Affect (FEFA) using faces and eye-pairs as target material. Additionally three attention-tasks (Sustained attention, Inhibition, Set-Shifting) were administered. Approximately 52% of the autistic children met the criteria for the comorbid diagnosis of ADHD. A MANOVA with post-hoc Scheffé tests revealed a significant difference in the recognition of faces and eye pairs between the group ADHD and controls (P = 0.009). Children with autism and ADHD also differed significantly from healthy participants in the recognition of eye-pairs (P = 0.009). Neither correlations with PDD nor with ADHD symptom scores were able to explain these results. Sustained attention and inhibition deficits had a significant influence on emotion recognition in children with ADHD. Our findings imply that the ability of facial affect recognition is reduced in children suffering from ADHD symptoms, both in autistic and pure ADHD children. ADHD symptoms need to be taken into account in future studies assessing emotion recognition in autistic children and adolescents.

Brief report: Comorbid psychiatric disorders of autistic disorder

Conclusion The behavioral and/or psychiatric symptoms in autistic people as described above have been viewed by many professionals dealing with autistic populations as associated features of autism that may result from these individuals' inability to cope with the environmental demands and physical discomfort. Traditionally, in treating individuals with autism, special education intervention including behavioral modifications has been the main emphasis. Such an approach has made some progress in milder and uncomplicated cases of autism. However, if many of these behavioral and/or psychiatric symptoms in those with more severe associated features can be viewed as symptoms of various comorbid psychiatric disorders, there are data suggesting that with an appropriate evaluation, predrug workups, a specific diagnosis, and multiple measures of outcome, pharmacotherapy can be a safe and efficacious adjunct treatment for some symptoms in autistic persons. Nevertheless, the data presented here were obtained mainly from autistic children. A great deal of work remains to be done Future research should put more emphasis on developing agreeable, reliable, and valid diagnostic instruments for identifying comorbid psychiatric disorders in autistic people. Future research should also emphasize employing a randomized double-blind placebo-controlled crossover design, as well as involving multicenters and using uniformed diagnostic criteria to study autistic adolescents and adults.     

Effect of Comorbid Psychopathology and Conduct Problem Severity on Response to a Multi-component Intervention for Childhood Disruptive Behavior

This study examined the effects of comorbid ADHD symptoms, internalizing psychopathology, Callous–Unemotional (CU) Traits, and conduct problem severity on children’s response to an evidence-based psychosocial intervention. Clinic-referred children with DBD ages 8–12 years (N?=?76) participated in a 15-week multi-component intervention. Parents provided weekly ratings of children’s oppositionality-defiance, peer problems, and impairment. Oppositionality-defiance, peer problems, and impairment decreased significantly over the course of the intervention; however, there was considerable variability in weekly ratings. Baseline ADHD symptoms, internalizing psychopathology, CU traits, and conduct problem severity were unrelated to rate of change across treatment. However, ADHD symptoms uniquely predicted more oppositionality-defiance, peer problems, and impairment averaged across the 15 weeks of treatment. Follow-up analyses suggested this was driven by hyperactivity-impulsivity rather than inattention. Children with DBD and comorbid symptoms appear to benefit from a multi-component intervention, but those with ADHD symptoms may require additional support to address social and behavioral challenges.     

Autistic Traits and Symptoms of Social Anxiety are Differentially Related to Attention to Others’ Eyes in Social Anxiety Disorder

Autism spectrum disorder (ASD) and social anxiety disorder (SAD) have partly overlapping symptoms. Gaze avoidance has been linked to both SAD and ASD, but little is known about differences in social attention between the two conditions. We studied eye movements in a group of treatment-seeking adolescents with SAD (N?=?25), assessing SAD and ASD dimensionally. The results indicated a double dissociation between two measures of social attention and the two symptom dimensions. Controlling for social anxiety, elevated autistic traits were associated with delayed orienting to eyes presented among distractors. In contrast, elevated social anxiety levels were associated with faster orienting away from the eyes, when controlling for autistic traits. This distinction deepens our understanding of ASD and SAD.     

Parent and teacher agreement in the assessment of pervasive developmental disorders

Although it is well known that informants often disagree about the degree of psychopathology in children, this issue has not been systematically evaluated in children with autism. The objective of this paper is to estimate the extent of agreement between parents and teachers on the assessment of autistic symptoms and adaptive behavior skills. We assessed 83 children, 4–6 years of age, with a diagnosis of pervasive developmental disorder (PDD), using the Autism Behavior Checklist (ABC) and the Vineland Adaptive Behavior Scales (VABS). Parents and teachers rated each child on each measure. While there was good agreement between informants on the VABS, teachers tended to rate the PDD children higher that parents. In contrast, there was virtually no agreement on the ABC. High levels of stress experienced by parents appeared to be associated with parents reporting more autistic behaviors and less adaptive skills than teachers. As with other child psychiatric disorders, caution must be exercised in combining information from several informants.This grant was supported by awards from the Ontario Mental Health Foundation, the Vellum foundation, and Health and Welfare Canada. The authors express their gratitude to the families and clinicians who participated in the project.     

Mental development and autistic behavior in children with pervasive developmental disorders

The aim of this study was to clarify the features of mental development and autistic behavior in children with pervasive developmental disorders (PDD) from the viewpoint of remedial therapy. The Tokyo Child Development Schedule (TCDS) and the Tokyo Autistic Behavior Scale (TABS), designed to be completed by children's caregivers, were used. A comparison was made of 36 children with PDD, 36 children with AD/HD, and 36 children with other diagnoses (OTHERS), who were matched about IQ and age. Although there were no significant differences between the three groups in terms of their overall scores on the TCDS and TABS, there were significant differences in specific areas on the tests. On the TCDS, the PDD group scored significantly lower than the AH/HD group and OTHERS group in Area V (Socialization). The PDD group also scored significantly lower than the AD/HD group in Area VII (Comprehension/Cognition). On the TABS, the PDD group had significantly higher scores than the AH/HD group in Area 2 (Language-Communication) and Area 3 (Habits-Mannerisms), and displayed significantly more autistic behavior. These findings suggest that children with PDD not only suffer from impairments in “qualitative impairment in social interaction” and “adapting to change,” but also have underdeveloped use of pointing, and impairments in “joint visual attention,” conceptualizing spatial relationships and language functions. They also suggest that in addition to general evaluations of development and autistic behavior, remedial therapies need to include more detailed assessments of children with PDD.     

Psychopathological features during childhood and adolescence among adult bipolar patients: A retrospective study

Objective

There are still several concerns regarding the inconsistency in the diagnosis of Bipolar Disorder (BD) in children and adolescents. This study reviews the symptoms of youth admitted to The University of Texas Harris County Psychiatric Center (UT-HCPC) prior to a confirmed diagnosis of BD to elucidate patterns and target symptoms which may facilitate early recognition of BD.

Methods

This is a retrospective review of charts of adult patients with a discharge diagnosis of BD for three consecutive admissions who were also admitted to UT-HCPC as children or adolescents (N = 26). The Kiddie SADS was completed based on each patient’s first admission as a child and last admission as an adult.

Results

Most of the symptoms found in adult BD were present in the child/adolescent subjects at equivalent rates, except for mood elevation, which was less common during childhood and adolescence. In spite of the psychopathological similarity, only 6 (23%) of the subjects were diagnosed with BD as youth.

Conclusion

BD is poorly diagnosed among children and adolescents. Difficulties in the assessment of the youth, as well as particularities in the psychopathology of mood among children and adolescents may account for the low diagnostic rate.     

The Comorbidity of Pervasive Developmental Disorder and Attention Deficit Hyperactivity Disorder: Results of a Retrospective Chart Review

Objective: To determine if a sample of children meeting diagnostic criteria for a Pervasive Developmental Disorder (PDD) display symptoms and impairment related to Attention Deficit Hyperactivity Disorder (ADHD) sufficient to warrant a comorbid diagnosis of ADHD. Further, do children with PDD displaying such symptoms demonstrate more impairment in daily life activities than those children only having PDD? Method: A retrospective chart review was conducted on children (N = 57) diagnosed with the PDD's of Autism or PDD-Not Otherwise Specified (PDD-NOS), or ADHD. Comparative analysis of questionnaire and neuropsychological test data was completed to determine the severity of ADHD-like symptoms presenting among children with PDD. Results: From the pool of subjects having PDD with sufficient data (N = 27), 7 or 26% met DSM-IV criteria for the combined type of ADHD. Nine or 33% met diagnostic criteria for the Inattentive Type of ADHD and 11 or 41% did not demonstrate a significant number of ADHD symptoms to warrant a comorbid diagnosis of ADHD. Results indicate that a subgroup of children with PDD displaying significant ADHD-like symptoms may in fact have ADHD thus warranting a comorbid diagnosis of ADHD. Current data did not suggest children with PDD and the combined type of ADHD demonstrated significantly more impairment in daily life functioning than those children only having PDD. However, this appeared likely the result of small sample size. The data, however, does indicate such children experience more difficulties in daily situations as rated by parents and teachers. Conclusion: These findings reinforce clinical observations indicating that some children with PDD may also experience an independent comorbid condition of ADHD, suggesting that a comorbid diagnosis of ADHD with PDD be considered in such cases. If further findings are replicated, the current exclusionary DSM-IV-TR criteria of making such a comorbid diagnosis should be re-considered.     

Suicidal behavior in adolescents and adults with bulimia nervosa

Background

Recent evidence suggests increased risk for mortality in bulimia nervosa (BN). However, little is yet known about suicidal behavior in BN.

Aims

To examine frequency and correlates of suicidal ideation and attempts in adolescents and adults with BN in two population-based samples.

Method

A total of 10,123 adolescents and 2980 adults in two nationally representative surveys of mental disorder were queried regarding eating disorder symptoms and suicidal ideation and attempts.

Results

Less than 1 percent (0.9%) of adolescents and 1.0% of adults met the criteria for BN. Suicidal ideation was more common among adolescents with BN (53.0%) compared with those with binge eating disorder (BED) (34.4%), other psychopathology (21.3%) or no psychopathology (3.8%). Similar trends emerged for the association between BN and self-reported suicidal plans or attempts. Among adults, suicidality was more common in BN than in the no psychopathology group, but not significantly different from the anorexia nervosa (AN), BED, or other psychopathology subgroups.

Conclusion

There is a high risk of suicidal ideation and behavior among those with BN. These results underscore the importance of addressing suicide risk in adolescents and adults with eating disorder symptoms.     

The presence or absence of certain behaviors associated with infantile autism in severely retarded autistic and nonautistic retarded children and very young normal children

The modified Behavior Observation Scale adapted from Freeman et al. was used to compare normal, retarded, and autistic children with very low developmental ages and to determine the types of behavior that could differentiate these three diagnostic categories of children. Examination of the data revealed that there was much more overlap between autistic and retarded children than between autistic and normal children. However, a behavioral pattern of autism could be delineated and very retarded autistic children could be distinguished from the nonautistic retarded children. The autistic behavioral pattern included subclusters of symptoms that might be interpreted as disturbances of sensory modulation and motility.This study was supported by C.N.R.S.
