Autism is a developmental disorder. The main characteristics of this disorder are one’s inability to socially interact in a proper manner, and one’s restricted and repetitive behavior. Some common behavioral habits of autistic children include stereotyped behaviors, compulsive behaviors, ritualistic behaviors, staying stuck to restricted interests, and self-injury. Autism is a disease with a complex genetic basis. Such complexity arises due to the interaction among multiple genes, epigenetic factors and the environment, which influence gene expression. The diagnosis of autism is based on an examination of behavior. Autism Diagnostic Interview-Revised and Autism Diagnostic Observation Schedule are commonly used diagnostic tools. Increasing functional independence and better quality of care are the focus areas of autism management. Intensive and sustained special education programs, along with speech and behavioral therapies, help autistic individuals to achieve better social skills and communication skills.
