It is estimated that up to 80% of children with Asperger Syndrome also experience intense anxiety symptoms. Anxiety Disorders such as Obsessive Compulsive Disorder, Social Anxiety, and Generalized Anxiety Disorder commonly co-occur with Asperger Disorder. Anxiety and depression may be reactive to their condition or may be constitutionally-based. ADHD is commonly diagnosed in children with AS. Nonverbal Learning Disability (NVLD) is a diagnosis which has the most overlap with AS. The characteristics of NVLD—problems with organization, motor planning, problem solving and prioritization, social adaptation, time perception—are also present in children with AS.
