Autism Spectrum Disorder (ASD) is a condition related to brain development that influences how a person comprehends and socializes with others. ASD causes problems in social interaction, communication and repetitive patterns of behaviour. The term "spectrum" in ASD refers to a wide range of symptoms and severity.
Autism spectrum disorder includes conditions such as — Autism, Asperger's Syndrome, Childhood Disintegrative Disorder, and an unspecified form of Pervasive Developmental Disorder.
Autism Spectrum Disorder begins in early childhood, causing problems — socially, in school and at work. Symptoms start to develop in the first year and then go through a period of regression between 18 and 24 months of age. There is no absolute cure for autism spectrum disorder, but early intervention can make a vast difference in the lives of many children.
