OBJECTIVE The effects of olanzapine and divalproex for the treatment of mania were compared in a large randomized clinical trial. METHOD A 3-week, randomized, double-blind trial compared flexibly dosed olanzapine (5-20 mg/day) to divalproex (500-2500 mg/day in divided doses) for the treatment of patients hospitalized for acute bipolar manic or mixed(More)
BACKGROUND The present study provides additional data on the psychometric properties of the 30-item Inventory of Depressive Symptomatology (IDS) and of the recently developed Quick Inventory of Depressive Symptomatology (QIDS), a brief 16-item symptom severity rating scale that was derived from the longer form. Both the IDS and QIDS are available in matched(More)

METHOD This 47-week, randomized, double-blind study compared flexibly dosed olanzapine (5-20 mg/day) to divalproex (500-2500 mg/day) for manic or mixed episodes of(More)
OBJECTIVE The purpose of this study was to assess the evidence base for the efficacy of light therapy in treating mood disorders. METHOD The authors systematically searched PubMed (January 1975 to July 2003) to identify randomized, controlled trials of light therapy for mood disorders that fulfilled predefined criteria. These articles were abstracted, and(More)
OBJECTIVE The authors evaluated the efficacy and safety of quetiapine plus lithium or divalproex in the prevention of recurrent mood events in patients with stabilized bipolar I disorder. METHOD A total of 1,953 patients received open-label quetiapine (400-800 mg/day in flexible, divided doses) with either lithium or divalproex (target serum(More)
OBJECTIVE The authors examined the comparative risks of switches in mood polarity into hypomania or mania during acute and continuation trials of adjunctive antidepressant treatment of bipolar depression. METHOD One hundred fifty-nine patients with bipolar I disorder or bipolar II disorder participated in a total of 228 acute (10-week) randomized trials(More)
Episode recurrence in bipolar disorder following discontinuation of stable maintenance treatment with lithium salts was analyzed from 14 studies involving 257 patients with bipolar I disorder. More than 50% of new episodes of illness occurred within 10 weeks of stopping an average of 30 months of treatment. By survival analysis of 124 cases in which the(More)
Bipolar disorder (BPD), probably the most prevalent psychotic disorder in adults, has been relatively neglected or controversial in children and adolescents over the past century. We reviewed the literature on early-onset BPD. Estimates of prevalence, particularly before puberty, are limited by historical biases against pediatric mood disorders and by(More)
