Development of behavioral and emotional problems in Tourette syndrome.

Tourette syndrome is a movement disorder with multiple neuropsychiatric features. Using the parent form of the Child Behavior Checklist by Achenbach and Edelbrock, we identified behavioral and emotional difficulties in 78 males, 6-16 years of age, with Tourette syndrome. Symptoms most often identified included obsessive-compulsive behavior, aggressiveness, hyperactivity, immaturity, withdrawal, and somatic complaints. Abnormal checklist scores were most prevalent in adolescents with Tourette syndrome. Tic severity was not a statistically significant predictor of behavioral disturbance, although a suggestive relationship between tic severity and behavioral disturbance was observed in the 12- to 16-year-old group. Dividing Tourette syndrome patients into those with or without hyperactivity failed to identify whether hyperactivity had a major impact on abnormal behaviors. Our results illustrate the relative frequency of psychopathology in Tourette syndrome and emphasize the need for a comprehensive approach to this syndrome.
