Visual event-related potentials and spline map topography during a discriminative response task (DRT) were studied in 8 obsessive-compulsive disorder (OCD) patients without comorbidity for panic disorder or depression and in 12 age-matched controls. In the DRT task (like in a go/no-go task) the subject had to press a button when the target stimuli appeared(More)
OBJECTIVE The aim of the present study was to evaluate the efficacy and safety of lithium and valproate in nonbipolar pathological gamblers. METHOD Forty-two subjects with DSM-IV-defined pathological gambling entered a 14-week single-blind trial with lithium (N = 23) or valproate (N = 19).

To the authors' knowledge, this is the first placebo-controlled treatment study in pathological gamblers with bipolar spectrum disorders; it(More)
BACKGROUND Pathological gambling is a disabling and highly prevalent impulse-control disorder not otherwise specified (NOS). According to the hypothesis of abnormal serotonin function in the pathophysiology of poor impulse control and pathological gambling, we assessed the efficacy and tolerability of nefazodone, a 5-HT antagonist reported to be effective(More)

METHODS We explored the 5-HT(1D) hypothesis in a 5-day, random, double-blind,(More)
