This study compared 21 children with pervasive developmental disorders (autism group) with 15 children with fragile X syndrome on the Childhood Autism Rating Scale and the Reiss Scales for Children's Dual Diagnosis. Seven of the fragile X children also scored in the autism range and were more impaired than the other fragile X children. (Contains…

A study examined the validity of the Screening Tool for Autism in Two-Year-Olds (STAT) as a stage 2 screening instrument in a clinic-based sample of two-year-olds with autism (n=12) and with nonautistic developmental disorders (n=21). Results provide preliminary support for the utility of the STAT as an early screening of autism. (Contains…

Diagnostic criteria for autism and background characteristics used by 937 Indian psychiatrists, psychologists, and pediatricians were examined. Generally, the three professions agreed about the characteristics most necessary for a diagnosis and these characteristics were in line with standards of the Diagnostic and Statistical Manual (III and IV).…

At least 60% of children with disabilities have multiple disabilities including visual impairments (VI). Because the visual system is neurologically based, any problems of the neurological system will also likely affect vision. The estimated number of students with VI and additional disabilities has increased significantly over the years. Since…

A study of the development of epilepsy in adolescents with autism investigated the brain dysfunctions in 158 patients (ages 15-28) with autism through the examination of paroxysmal electroencephalographic abnormalities. Results indicated that 47.5% of the individuals with autism had such abnormalities in the frontal region. (CR)

Children (n=132), ages 1-16, were diagnosed for autism using the criteria in the International Classification of Diseases (ICD-10), Childhood Autism Rating Scale, Autistic Behavior Checklist, and third and fourth editions of the Diagnostic and Statistical Manual of Mental Disorders (DSM). Agreement of the DSM-IV and ICD-10 with the other…

A Japanese study measured CSF (cerebrospinal fluid) levels of beta-endorphin in 19 children (ages 4-6) with infantile autism and in 3 children (ages 10-14) with Rett syndrome. In infantile autism, levels did not differ significantly from control participants (n=23). However, levels were significantly higher in those with Rett syndrome. (Author/CR)

This population study of eight California birth cohorts (1987-1994) examined the degree to which improvements in detection and changes in diagnosis contribute to the observed increase in autism prevalence from 5.8 to 14.9 per 10,000. A decreasing prevalence of mental retardation without autism suggests that improvements in detection and changes in…

This study of 102 individuals with autism found that the brainstem and cerebellum increased in size with age but were significantly smaller in autistic patients than in controls. Analysis of the speed of development suggests that brainstem and vermian abnormalities in autism were due to an early insult and hypoplasia rather than to progressive…

A review of 32 epidemiological surveys of autism and pervasive developmental disorders found four surveys yielded estimates for childhood disintegrative disorder (CDD) ranging from 1.1 to 6.4 per 100,000. It is concluded that CDD is very rare and its prevalence is 60 times less than that of autistic disorder. (Contains references.) (Author/CR)

Recent years have seen a surge of interest in assessment instruments for diagnosing autism in children. Instruments have generally been developed and evaluated from a research perspective. The Autism Diagnostic Observation Schedule-Generic (ADOS-G), Autism Diagnostic Interview-Revised (ADI-R), and Gilliam Autism Rating Scale (GARS) have received…

The study investigated the effectiveness of three instruments in discriminating 20 autistic from 20 trainable mentally retarded children (ages 3-12): Autism Screening Instrument for Educational Planning (ASIEP), Childhood Autism Rating Scale (CARS), and Diagnostic Checklist for Behavior Disordered Children. The CARS and ASIEP provided for a…

A study of the status of underidentification of behaviorally disordered children in special education in British Columbia reviews provincial funding categories, identification guidelines for autism and behavior disorders, and data on total school enrollment, estimated and actual enrollment in programs for behavior disorders, district criteria, and…

The case study of a 12-year-old boy, originally diagnosed as hearing impaired and in need of socialization, is reported to demonstrate the effects of misdiagnosis. The child was later diagnosed as autistic and more useful interventions were initiated. (PHR)

This paper offers guidelines to compare the characteristics observed in children with autism and blindness and those observed in children with blindness alone. It distinguishes between stereotypic behaviors (blindisms) in blind individuals and similar stereotypic behaviors of children with autism. A table presents typical behavior patterns of…
