This paper reports on six children who all fulfill the criteria for fetal alcohol syndrome and have a history of maternal alcohol abuse during pregnancy, and who also fulfill the criteria for diagnosis of autism. Their behavior and natural history is compared with eight contrast FAS children, of similar ages and functional levels, who were free of autistic behaviors. The autistic FAS children were all moderately or severely retarded. Autistic behavior has not been commonly associated with prenatal alcohol exposure. Clinicians need to be aware of this potential dual diagnosis so that appropriate educational and treatment resources can be employed.

The Aberrant Behavior Checklist (ABC; Aman, Singh, Stewart, & Field, 1985a, 1985b) is a 58-item third-party informant rating scale originally developed for institutionalized, low-functioning adolescents and adults. The present study investigated the appropriateness of the scale for youngsters with dual diagnosis of mental retardation and psychiatric disturbance. Over a period of 2 1/2 years, 204 patients (199 after data reduction) from a child psychiatry unit were rated twice daily by direct care staff. Data analysis addressed internal consistency, interrater reliability, criterion validity, and robustness of the factor structure. Internal consistency was satisfactory with alpha coefficients ranging from .82 to .94. Interrater reliability varied between subscales but was relatively low (Pearson correlations between .39 to .61). In terms of its criterion validity, the ABC was sensitive to psychiatric diagnoses and age and the original 5-factor structure was robust (congruence coefficients ranged between .80 to .89). Yet, only a relatively small proportion of the variance (31.5%) was explained by factor analysis indicating possible limitations of the ABC for this population. Given the paucity of assessment instruments for this particular population and the difficulty involved in developing new population-specific instruments, the ABC can be recommended for children and adolescents with dual diagnosis.

Although autistic-like behaviors were described even in the earliest reports of fetal alcohol syndrome, it was only recently that fetal alcohol syndrome and autism were reported as a dual diagnosis in six school-aged children. The purpose of the present series of case reports is to describe marked autistic characteristics in three much younger children (25-36 months) with histories of prenatal exposure to alcohol and other drugs. The behavioral characteristics of these children are described and compared with current diagnostic criteria for autistic disorder. In addition, longitudinal scores on the Bayley Scales of Infant Development are provided to underscore the marked developmental delays shown by each of the children. Limitations of these case reports are discussed with suggestions for future prospective research.

The recent advent of atypical antipsychotic medications has provided new clinical options and set higher expectations for the treatment of schizophrenia and other psychoses. Two such drugs, clozapine and risperidone, are currently employed in the United States. Researchers continue to fine-tune treatment with these agents and to seek possible new uses for them. For clozapine, refinements in use (optimal duration of trial, optimal dose, use of drug plasma level to optimize efficacy) are described, along with side effects and the specificity (or lack thereof) of the drug's action upon primary negative symptoms. Also discussed is use of clozapine in new subgroups of patients--for example, those with first-episode schizophrenia, polydipsia syndrome, or a dual diagnosis. For risperidone, use in patients with first-episode schizophrenia, affective disorders, autism, and other disorders in described. Cost-benefit considerations are presented for both drugs. The psychosocial needs of patients taking these medications and the potential for synergy between novel antipsychotics and modern psychosocial therapies are also discussed.

Cohen syndrome is a rare, genetic, connective-tissue disorder, with the genetic abnormality linked to chromosome 8q22. Its physical features (particular facial characteristics; body, limb, and visual abnormalities; height and weight problems) have been well documented but little is known about the psychological and behavioural development of individuals with the condition. Suggestion of a dual diagnosis of autism in a small minority of individuals led to a more detailed survey of parents belonging to the Cohen Syndrome Support Group, based in the UK. Thirty-three individuals, 18 males and 15 females, aged from 2 to 45 years (mean age 15 years) were involved in the study. Over half of the participants (n=19) showed a pattern of impairments in social and communication skills, together with rigid and stereotyped behaviours or interests that seemed to meet DSM-IV/ICD-10 criteria for autism. 'Autistic-type' problems were as common in females as in males. In almost all cases, parents had noted difficulties in their child before the child reached the age of 1 year. This study suffers from a number of methodological shortcomings including the fact that it was a postal survey, the sample size was small, and no standardized diagnostic or psychometric data were available. However, the incidence of social, communication, and behavioural problems would seem to warrant further research and a larger-scale study is planned in association with an independent investigation of physical and genetic characteristics in the same group of individuals.

Although the DSM-IV diagnostic criteria for Attention Deficit/Hyperactivity Disorder (AD/HD) exclude Pervasive Developmental Disorder (PDD), some clinicians find that the two disorders can be comorbid and, in fact, make a dual diagnosis. Nevertheless, few empirical studies have investigated the clinical necessity for this practice. In the first of our two studies, children with high-functioning PDD were selected from among 520 outpatients. Of these, children also meeting the DSM-IV criteria for AD/HD were identified through a psychologist's observation, the completion of the ADHD-Rating Scale by parents and/or teachers, and a child psychiatrist's examination. We then examined the impact of PDD subtype and age on the co-occurrence rate. Study 2 analyzed comorbidity in two cases taken from Study 1. Of the 53 subjects in Study 1, 36 children also met the DSM-IV criteria for AD/HD. The co-occurrence rate for Asperger's Disorder (AS)/Pervasive Developmental Disorder, Not Otherwise Specified (PDDNOS) (85%) was significantly higher than for Autistic Disorder (57.6 %), and AD/HD symptoms were more common in younger children. Study 2 demonstrated the existence of comorbidity of PDD and AD/HD as separate disorders. We conclude not only that AD/HD symptoms occur frequently in children with PDD, but also that in some cases a dual diagnosis is essential to the implementation of effective treatment.

To examine the behavioral and emotional difficulties of 73 children and adolescents with Prader-Willi Syndrome (PWS), mental retardation-only, and dual diagnosis (i.e., mental retardation and psychiatrically disordered) on the Devereux Scales of Mental Disorders (DSMD: Naglieri, LeBuffe, & Pfeiffer, Devereux Scales of Mental Disorders (DSMD) San Antonio, TX: PsychCorp 1994). Multivariate analyses and "Italic">d-ratios were computed to assess the statistical and clinically meaningful differences between pairs of samples. The PWS sample exhibited statistically significant higher levels of psychopathology than the mentally-retarded-only sample on the Total, Externalizing, Internalizing, Attention/Delinquency, Conduct, Anxiety, and Acute Problems Scales. When compared to the dually-diagnosed sample, children with PWS Syndrome had comparable levels of psychopathology, but lower levels of depression. Results revealed that PWS represents a highly unique and complex psychological disorder with multiple areas of disturbances.

In this investigation, the socio-communicative skills of 29 children with Williams syndrome aged 2 (1/2) to 5 (1/2) years were examined using the Autism Diagnostic Observation Schedule (ADOS) Module 1. Most of the participants showed socio-communicative difficulties. Approximately half of the participants were classified by the ADOS algorithm as "autism spectrum." Three participants were classified "autism." Difficulties with pointing, gestures, giving, showing, and eye contact were present for more than half of the participants, with many also showing difficulties with initiation and response to joint attention and with integration of gaze with other behaviors. Expressive and receptive language abilities of the children with Williams syndrome classified "autism spectrum" were weaker than for children classified nonspectrum, but expressive and receptive language level did not account for the socio-communicative difficulties. Implications for our understanding of the socio-communicative abilities of young children with Williams syndrome and diagnostic practices regarding dual diagnosis are discussed.

Obsessive Compulsive Disorder (OCD) involves exaggerated or excessive worry about threatening and non-threatening stimuli coupled with impairing rituals believed to reduce anxiety. Autism Spectrum Disorders (ASD) are characterized by impairment in social and communicative activities as well as restricted and repetitive behaviors. Approximately 2% of children with ASD are also diagnosed with OCD. Although there is extensive research demonstrating the effectiveness of behavioral interventions for pediatric OCD, little is known about how effective these treatments are for children who have a dual diagnosis of OCD and ASD. This report describes a 12-year-old male with Autism who was treated successfully with cognitive behavioral therapy with exposure and response prevention. This case study provides initial support that cognitive-behavioral therapy is effective in symptom reduction for children with comorbid autism and OCD.

Construct validity of the Motivation Assessment Scale (MAS) (Durand, Crimmins, The Motivation Assessment Scale 1988) was studied using Rasch analysis data from 67 children (246 MASs), with dual diagnosis of autism and intellectual disability or with intellectual disability only. Results failed to support the proposed unidimensional construct or the original 4-factor structure. Some motivators appear to form a unidimensional construct: "to gain attention", "to gain a tangible object", and "to escape". There was evidence that sensory stimulation represents a different construct. Children with intellectual disability were more apt to be motivated by desire to gain a tangible item or attention. Children with the dual diagnoses were more apt to have sensory stimulation or escape from task demand as a motivator for stereotypic and repetitive behavior.
