Bupropion effects in attention deficit and conduct disorders.

Children with Attention Deficit and/or Conduct Disorders were treated with bupropion, a new antidepressant, to determine its clinical, cognitive, and EEG effects. Seventeen male patients (age range 7 to 13.4 years; mean 10.4) participated in an open clinical trial consisting of a baseline placebo period (4 weeks), bupropion therapy (8 weeks), and post-drug placebo (2 weeks). Evaluations included clinical assessments, parents, teachers, and self-ratings; cognitive tests and blood level measurements of bupropion. Fifteen patients received a daily maximum of 150 mg, one received 100 mg and one 50 mg. Clinical global improvement with bupropion therapy was marked in 5 patients, moderate in 7, mild in 2, and none in 3. The Children's Psychiatric Rating Scale indicated improvements of hyperactivity, withdrawal, anxiety, hostility/uncooperativeness, sleep disorder, antisocial behaviour, neuroticism, depression and eating disturbance. Parents' Questionnaires indicated significant improvements of conduct disorder, anxiety, hyperactivity, muscle tension and psychosomaticism. While no single cognitive test showed significant improvement, all nine tests changed in the positive direction. Adverse effects were infrequent, transient and mild. There were no clinically significant changes of the laboratory values and vital signs. Two weeks following bupropion discontinuation, clinical global improvement was maintained in 8 patients, 7 showed relapses, while 2 remained unimproved. Analyses of computerized EEG revealed that degree of clinical improvement was indexed by baseline EEG parameters and that there were significant bupropion effects on EEG measures. Double-blind trials of bupropion are recommended in child psychiatry disorders.
