Doctor's Notes on Autism Spectrum Disorders Signs, Symptoms, Causes, Types, Treatment, and Cure

Autism spectrum disorder (ASD) is a developmental disorder with three defining core features: problems with social interactions, impaired verbal and nonverbal communication, and a pattern of repetitive behavior with narrow, restricted interests.

There is a wide range of symptoms and behaviors that comprise autism spectrum disorder (ASD), and these may include impaired reciprocal social interaction (difficulty interacting with others), impaired communication (speech delays, difficulty expressing themselves), and a restricted repertoire of interests, behaviors, and activities. Many people with autism have problems using language, forming relationships, and appropriately interpreting and responding to the external world around them. Other symptoms and behaviors seen in some people with autism may include problems with cognitive function, seizures, problems with fine motor skills, behavioral problems, and variations of mood and affect.
