Background: Disturbances in thought, speech, and linguistic processing are frequently observed in bipolar manic patients, but the underlying neurophysiological mechanisms are not well understood. P600 is a distinct, positive event-related potential component elicited by syntactic violations. Using the P600 ERP, we examined neural processing of syntactic language comprehension in patients with b...

Acute Mania Quetiapine XR (FDA approved for the treatment of acute mania) monotherapy has been shown to be more effective than placebo in treating acute mania with improvement starting at day 4. Aripiprazole adjunctive therapy was more effective than placebo adjunctive therapy in treating manic symptoms in BD manic patients with inadequate response to lithium or divalproex in a 6 week trial. Ol...

Background and Objectives: Aggressiveness is a common component of manic symptoms. The aim of this study was to determine the clinical characteristics associated with aggressive behaviour in bipolar patients with acute manic episodes. Methods: A study was carried out with 173 patients who met the DSM-IV criteria for manic or mixed bipolar disorder. Clinical and demographic variables were evalua...

Higher numbers of manic episodes in bipolar patients has, in cross-sectional studies, been associated with less grey matter volume in prefrontal brain areas. Longitudinal studies are needed to determine if manic episodes set off progressive cortical changes, or if the association is better explained by premorbid brain conditions that increase risk for mania. We followed patients with bipolar di...

BACKGROUND Sibutramine, used in obesity treatment, has been associated with many neuropsychiatric side effects including hypomanic and manic episodes. Hypomanic/manic episodes related to sibutramine treatment were earlier reported in patients who had previous history of bipolar disorder, after sibutramine overdose, after over-the-counter product illegally containing very high dose of sibutramin...

OBJECTIVE Bipolar disorder is a severe, recurrent, and often chronic psychiatric illness associated with significant functional impairment, morbidity, and mortality. Creatine kinase is an important enzyme, particularly for cells with high and fluctuating energy requirements, such as neurons, and is a potential marker of brain injury. The aim of the present study was to compare serum creatine ki...

BACKGROUND Bipolar I Disorder (BID) considered as the sixth leading cause of disability worldwide. After remission of a manic episode, most of patients spend about 50% of the following time with mood or cognitive symptoms. The aim of this study was to investigate the 6-month outcome of BID patients following their single manic episode. METHODS Adult bipolar patients (n = 13) with single manic...
