Asperger's disorder refers to a Subtype of pervasive developmental disorder that is identical to autism (oddities in social interaction, stereotyped behaviour), with the exception that there is no clinically significant delay in language.
Asperger's disorder is characterized by impairments or difficulties in social relationships and interaction in children witrh relatively intact cognitive and communication skills or without the language delays which is seen in Autism. Children with this disorder also develop restricted, repetitive, and stereotyped patterns of behavior, interests, and activities.
Asperger's Disorder is also called as AD.
