Efficacy and Tolerability of Topiramate in Treatment of Bipolar Mania and Alcohol Use in Adolescents and Young Adults

Specific Aim 1: To collect preliminary data regarding the efficacy and tolerability of topiramate for the treatment of alcohol use disorders (alcohol abuse and dependence) in adolescents with bipolar disorder.

Hypothesis 1: We hypothesize that topiramate in combination with quetiapine will lead to greater reduction in alcohol consumption (number of drinks per day, number of drinks per drinking day, and number of heavy drinking days) and greater abstinence (percentage of days abstinent) compared with quetiapine alone.

Specific Aim 2: To obtain preliminary data regarding the efficacy of topiramate for reducing manic symptoms in adolescents with co-occurring alcohol use and bipolar disorders.

Hypothesis 2: We hypothesize that the topiramate in combination with quetiapine will produce greater reduction in Young Mania Rating Scale (YMRS) scores than quetiapine alone.
