Alberta Education provides funding to school authorities to support the development and implementation of programming for students with severe disabilities. The Handbook for the Identification and Review of Students with Severe Disabilities presents case studies to assist school authorities in identifying students who may be eligible for special…

This paper explores issues and implications for diagnosis and treatment, stemming from the growing number of children identified with autism spectrum disorders (ASDs). Recent developments and innovations in special education and Medicaid programs are emphasized. Eligibility determination policies, innovations in diagnostic practices, the cost and…

The reliability, validity, and clinical utility of the Asperger Syndrome Diagnostic Scale in the diagnosis of pervasive developmental disorders are reviewed. While the measure holds promise as a research tool, there appears little evidence that it can distinguish among the variety of types of pervasive developmental disorders, or diagnose Asperger…

This study investigated early clinical differences between 27 children (ages 0-4) with pervasive developmental disorder not otherwise specified and 27 children with attention deficit disorder. Results revealed almost no differences between both groups with respect to pregnancy or birth complications and suggest that differences become more…

A two-stage protocol for screening for autistic spectrum disorders (ASD) was evaluated in a random population of 31,724 children aged 14-15 months. Children were first pre-screened by physicians at well-baby clinics using a 4-item screening instrument. Infants that screened positive were then evaluated during a 1.5-h home visit by a trained…

The objective of this review is to clarify the role of matching in family genetic studies of autism as a way of defining endophenotypes for linkage analysis. The concept of a confounding variable is reviewed and the importance of considering these in family studies of three endophenotypes in autism are considered: cognitive/language impairments,…

Diagnosis of pervasive developmental disorders relies on the detection of deficits in social, play, and communication skills relative to the child's mental age. A case example illustrates the multidisciplinary process of making the diagnosis in very young children. Psychiatric evaluation criteria are examined, and a developmental framework for…

An approach to the diagnosis of pervasive developmental disorders is presented that considers the difficulties in relationships and communication secondary to sensory and motor processing deficits. These difficulties are conceptualized as Multisystem Developmental Disorder (MSDD), and case vignettes illustrate typical patterns of MSDD and…

Although it is generally accepted that the proportion of children diagnosed with pervasive developmental disorders (PDDs) has increased in the past two decades, there is no consensus on the prevalence of these conditions. The accompanying large rise in demand for services, together with uncertainty regarding the extent to which the observed…

Special education is now an established part of public education in the United States--by law and by custom. However, it is still widely misunderstood and continues to be dogged by controversies related to such things as categorization, grouping, assessment, placement, funding, instruction, and a variety of legal issues. The purpose of this…

This monograph addresses common misconceptions about developmental disabilities, describes the conditions that child welfare workers are most likely to see, provides examples of effective interventions, and stresses the importance of early intervention to promote healthy development. Specific chapters include: (1) "Understanding Developmental…

Children with autism present unique challenges related to communication, behavior, and social skills. Each child with an autistic spectrum disorder (ASD) exhibits individual characteristics of the disorder. Early identification of autistic spectrum disorder has been shown to improve the child's benefit from educational interventions. There may be…
