Tourette disorder and bipolar symptomatology in childhood and adolescence.

Three boys with an early history of attention deficit disorder with hyperactivity developed Tourette disorder. At 13, 12 and eight years of age, respectively, each met DSM-III criteria for a manic episode or bipolar disorder. Each of the boys had a family history of affective or affective spectrum disorder. Lithium carbonate in a range of 0.8 to 1.2 meq/L markedly improved their bipolar symptomatology with Tourette symptoms improving in two patients. Further study is suggested to determine the significance of these findings.
