Children with intellectual and developmental disabilities are at heightened risk for mental disorders. Using current diagnostic criteria, disruptive behavior disorders, specifically Attention-Deficit/Hyperactivity Disorder (ADHD), appear to be the most prevalent co-occurring disorders. However, the validity of ADHD as a diagnosis for children and…

Chromosomal microarray analysis (CMA) has emerged as a powerful new tool to identify genomic abnormalities associated with a wide range of developmental disabilities including congenital malformations, cognitive impairment, and behavioral abnormalities. CMA includes array comparative genomic hybridization (CGH) and single nucleotide polymorphism…

This article summarizes Canadian research in "dual diagnosis" spanning the past 20 years and places this research within a historical and policy context. Canadian researchers have made important contributions with regard to understanding inpatient and outpatient mental health services, families, autism, specific disorders and behaviors,…

Objective: ADHD is a commonly diagnosed neuropsychological disorder among school-aged children with reported high rates of coexisting or comorbid disorders.

Twenty percent experienced either suicidal ideation, threats of, or attempts at suicide, with hanging being most frequently considered. Suicidality was most often encountered in individuals with oppositional defiant…

In response to a paper on effects of risperidone on behavior in people with developmental disabilities, this paper raises the issue of how clinicians determine whether treatment should target the psychiatric disorder underlying the aberrant behavior (diagnosis-based treatment) or should target the aberrant behavior directly (behavior-based…

This survey of the instruments and methods that are currently available for assessing mental health problems in persons with mental retardation lists formalized instruments and interview techniques and evaluates them from a methodological perspective. Emphasis is on the assessment and classification of disorders rather than on the evaluation of…

A study was conducted of 217 clients with developmental disabilities and behavioral and psychiatric disorders, who had been referred for crisis intervention, to determine what factors predicted their rereferral.
