Bipolar disorder has the highest rate of association with cocaine and other substance use disorders than any other major severe psychiatric syndrome. This comorbidity represents a major treatment challenge and is associated with severe disability, morbidity, and heightened risk for suicide.
The aims of this study are:
1. Examine the efficacy of valproate plus treatment as usual compared to placebo plus treatment as usual in decreasing cocaine use in patients with cocaine dependence and comorbid bipolar disorder.
2. Determine whether primary vs. secondary cocaine dependence, bipolar subtype (depressed vs. manic/mixed) and the presence of additional substance use disorders moderate the association between treatment and cocaine use outcome.
3. Assess the effects of medication compliance and mood symptoms as mediators of cocaine use outcome.
