Autism Spectrum Disorders and Their Clinical Management

Abstract

Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder marked by impairments in social behavior and difficulties with repetitive and restrictive behaviors. In 2012, the prevalence of ASD in the United States was estimated to be one in 68 among children age 8 years. Although the etiology of ASD is poorly understood, many researchers have identified genetic, epigenetic, and environmental factors likely involved in the disorder. In approximately 10% of cases, a definitive association with a specific genetic defect can be identified. A diagnosis of ASD is best performed through an interdisciplinary assessment and is based on diagnostic criteria. The DSM-5 criteria on the clinical features of ASD fall into two core domains: impaired social communication and interaction and restricted, repetitive behaviors, interests, or activities. Today, although no definitive “cure” for ASD exists, state-of-the-art therapies and learning environments, along with medications, have resulted in reducing disease burden and quality of life for individuals affected by ASD.
