The efficacy of vortioxetine 10 and 20 mg/d vs. placebo on cognitive function and depression in adults with recurrent moderate-to-severe major depressive disorder (MDD) was evaluated. Patients (18-65 yr, N = 602) were randomized (1:1:1) to vortioxetine 10 or 20 mg/d or placebo for 8 wk in a double-blind multi-national study. Cognitive function was assessed(More)
Contemporary mechanistic models of several psychiatric disorders propose abnormalities in the structure and function of distinct neural networks. The cerebellum has both anatomic and functional connections to the prefrontal cortex, the subcortical limbic structures and monoamine-producing brainstem nuclei. Conspicuously, however, the cerebellum has been(More)
OBJECTIVE To review extant literature implicating inflammation in the pathophysiology of bipolar disorder. Furthermore, we review evidence regarding the anti-inflammatory actions of mood-stabilizing medication, the putative reciprocal association of inflammation with behavioral parameters and medical burden in bipolar disorder, and the potential role of(More)
Incomplete response to monoaminergic antidepressants in major depressive disorder (MDD), and the phenomenon of neuroprogression, suggests a need for additional pathophysiological markers and pharmacological targets. Neuronal zinc is concentrated exclusively within glutamatergic neurons, acting as an allosteric modulator of the N-methyl D-aspartate and other(More)
BACKGROUND Symptomatic remission is the optimal outcome in depression. A brief, validated tool for symptom measurement that can indicate when remission has occurred in mental health and primary care settings is unavailable. We evaluated a 7-item abbreviated version (HAMD-7) of the 17-item Hamilton Depression Rating Scale (HAMD-17) in a randomized controlled(More)
OBJECTIVE Neuroimaging investigations reveal changes in glucose metabolism (fluorine-18-fluorodeoxyglucose positron emission tomography [PET]) associated with response to disparate antidepressant treatment modalities, including cognitive behavior therapy (CBT), antidepressant pharmacotherapies, and deep brain stimulation. Using a nonrandomized design, the(More)
Mood disorders have been recognized by the World Health Organization (WHO) as the leading cause of disability worldwide. Notwithstanding the established efficacy of conventional mood agents, many treated individuals continue to remain treatment refractory and/or exhibit clinically significant residual symptoms, cognitive dysfunction, and psychosocial(More)
METHODS Patients (n=302) with bipolar I disorder (manic episode) were randomised to 12 weeks' double-blind treatment with quetiapine (flexibly dosed up to 800 mg/day), placebo, or haloperidol (up to 8 mg/day). The primary efficacy outcome variable was change from baseline to Day 21 in Young Mania Rating Scale (YMRS) score. RESULTS YMRS score improved with(More)
OBJECTIVE This is the first cross-national population-based investigation exploring the prevalence and functional implications of comorbid general medical disorders in bipolar disorder. METHODS Data were extracted from the Canadian Community Health Survey (N = 36,984). Analyses were conducted to ascertain the prevalence and prognostic implications of(More)
OBJECTIVE A 26-week, double-blind, placebo-controlled relapse prevention study of aripiprazole was designed a priori with a prospective, 74-week, double-blind, placebo-controlled extension phase. Efficacy and tolerability of aripiprazole for relapse prevention in bipolar I disorder was, therefore, evaluated for 100 weeks. METHOD Patients with DSM-IV(More)
