It is a brain disorder that typically affects a person’s ability to communicate with others. ASD form of disease generally begins in childhood and last through adulthood.
Types of ASDs are:
• Autistic Disorder (also called “classic” autism): This is what most general form of autism. People with autistic disorder typically have significant language interruption, social and communication challenges, and unusual behaviors and interests. Many people with this disorder may also have intellectual disability.
• Asperger Syndrome: People with Asperger syndrome, have mild symptoms of autistic disorder. They might have social challenges and unusual behaviors and interests. However, they typically do not have problems with language or intellectual disability.
• Pervasive Developmental Disorder(PDD): It is called as “atypical autism”. People who meet some of the criteria for autistic disorder or Asperger syndrome, but not all, may be diagnosed with PDD-NOS. People with PDD usually have fewer and milder symptoms than those with autistic disorder. The symptoms might cause only social and communication challenges.
