Individuals with Developmental Disabilities

Persons with developmental disabilities (DD), such as autism spectrum disorder and intellectual disability, are at substantially greater risk of having comorbid mental illness compared to the general population. Their mental health care needs, however, are vastly undertreated. Contributors to this situation include the challenges of evaluating mental illness in individuals with DD; stigma associated with and systematic barriers against people with DD; communication barriers; inadequate training of health care workers; insufficient availability of community mental health services; and the complexity of the available social services and legal systems at the federal, state, and community levels. This chapter uses a case to review the different factors that contribute to irritability and problem behavior in a person who has autism spectrum disorder with intellectual and language impairment. Also reviewed is the complicated system of services and statutes that may be of assistance when working with this population.
