Developmental Disorder (PDD) characterized by severe and sustained impairment in social interaction, development of restricted and repetitive patterns of behavior, interests, and activities. These characteristics result in clinically significant impairment in social, occupational, or other important areas of functioning. In contrast to Autistic disorder (Autism), there are no clinically significant delays in language or cognition or self help skills or in adaptive behavior, other than social interaction. A large number of children are diagnosed between the ages of 5 and 9. Motor delays, clumsiness, social interaction problems, and idiosyncratic behaviors are reported. Adults with Asperger's have trouble with empathy and modulation of social interaction - the disorder follows a continuous course and is usually life long. Aspergers is not easily recognizable - in fact, many children are misdiagnosed with other neurological disorders such as Tourette's
Syndrome or Autism. More frequently, children are misdiagnosed with Attention Deficit (and Hyperactivity) Disorders (ADD & ADHD), Oppositional Defiant Disorder (ODD), or Obsessive-Compulsive Disorder (OCD).
