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)

A study examined 391 adult referrals to a mental health clinic serving individuals with mental retardation to explore the relationship between referral source and referral reason. Externalizing behaviors were found to be the most common referral reason; however, referral reason did vary as a function of referral source. (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…

Comparison of community children referred for learning disability evaluation (CR, n=17) with children not-referred in community general education (CGE, n=161), community special education (CSE, n=30), or from outpatient hospital referrals (HR). CR group performance was equivalent to that of CSE and HR groups. Results suggest conceptualizing…

Investigates how disability is discovered, constructed, and performed in a certain type of cultural practice, that is, in a postmodern, undergraduate college classroom. Argues that the implementation of an autobiographical pedagogy must extend beyond the dimensions of race, gender, and sexuality and must include disabled persons in these…

The scores of 15 children (ages 5-10) with learning disabilities on the Test of Visual Perceptual Skills and the Developmental Test of Visual Motor Integration revealed that visual perception and visual motor skills are separate, though related, functions and that visual motor scores were significantly lower than visual perception scores. (JDD)

This study found that 331 Toronto (Ontario, Canada) adolescent and adult subjects with learning disabilities could be grouped into three subtypes: (1) arithmetic disability, (2) reading disability, and (3) reading and arithmetic disabilities. Each group differed significantly from the others on tests of reading, spelling, memory, and other…

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…

Classification of arithmetic disorders is predicated on neuropsychological features and associated learning disabilities. Assesses the compatibility of these classifications on a nonreferred, population-based cohort of children (N=139) with developmental dyscalculia. Concludes that children with dyscalculia and disabilities in reading and/or…

Usable responses from 54% of adult-basic-education providers (n=555) in nine states identified how they determine whether adult clients have disabilities, the number with disabilities, and the total with disabilities in the region. Inner city/urban and smaller programs reported significantly more clients with disabilities. (SK)

Explores use of tests with more- vs. less-precise age norms to identify disabilities in preschool children. Standard scores associated with the same raw score shifted gradually across age groups on tests with more precise norms, and shifted more dramatically on tests with less precise norms. Indicates that many preschool tests have norm tables…

A study involving 18 emergency homeless shelters in Los Angeles screened 169 homeless children (ages 6-12) for behavior disorders, learning disabilities, or mental retardation. Results found almost one half of sheltered homeless children screened positive for at least one disability requiring special education services, with behavior disorders…

A review of the literature finds that the criteria developed by Stark and Tallal (1981) for the selection of children with specific language impairment for research purposes continue to be used, in part or in whole, in current research. Additional information on the use of norm-referenced tests with this population is also provided. (Author/DB)
