Over time, psychiatrists have developed a systematic way of describing autism and related conditions. These conditions are placed within a group of conditions called Autism Spectrum Disorder (ASD). Specifically, The American Psychiatric Association in 2013 released its edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) and changed the diagnosis of all autism and associated conditions as Autism Spectrum Disorder (ASD).
Definition of ASD:
ASD includes a group of developmental disabilities that can cause significant social, communication, and behavioral challenges. The disorder is often characterized by impairments in social interaction and communication, as well as restricted, repetitive, and stereotyped patterns of behavior. The impairment and the learning, thinking, and problem-solving abilities of individuals with ASD can vary ranging from gifted to severely challenged. Some individuals with ASD may require considerable help, while others may need less assistance in their daily lives.
