Co-occurring disorders

Forty percent of children with TD have attentional problems, and 30 to 40% have academic difficulties which require intervention. The academic problems are generally secondary to attentional problems. Another possible problem area (for possibly as many as 80% of TD children) is preoccupation with obsessions and compulsions. Some (25 to 30%) may experience difficulties in controlling their aggression, which can lead to social problems.
