Active clinical trials for "Bipolar Disorder"

This study looks at the role of a specific brain chemical system in the mood and attention symptoms seen in major depression and bipolar disorders using functional brain imaging.

This study will examine the safety and effectiveness of the antipsychotic drug olanzapine in children and adolescents with bipolar disorder or psychosis.

The purpose of this study is to assess the efficacy and safety of continued combination therapy using Depakote plus olanzapine, vs. Depakote monotherapy and olanzapine monotherapy in stable subjects during the maintenance phase of bipolar illness.

Aripiprazole is a new antipsychotic agent which possesses unique capabilities compared to other antipsychotic agents, especially because of its partial dopaminergic agonistic activity. Moreover, like the other atypical agents, aripiprazole is an antagonist of the 5-HT2a receptor, and an agonist of the 5-HT1a receptor. These pharmacological properties should enable this molecule to provide antidepressant potentiating capabilities based on what has been observed with other compounds sharing similar pharmacological profiles. Aripiprazole is now well recognized for its capacity to potentiate antidepressants in the treatment of unipolar depression. However, two randomized controlled trials of aripiprazole in the treatment of bipolar depression were negative. This surprising result may stem from the fact that the doses of aripiprazole used in these studies were rather high (17.6 ± 8.3 mg/d in study 1 and 15.5 ± 7.5 mg/d in study 2) and could have contributed to inhibit dopaminergic activity in key brain areas involved in the modulation of rewards, motivation and concentration. Bipolar depression is indeed heavily loaded with general symptoms of psychomotor retardation including poor concentration, low energy level, hypersomnolence, and hyperphagia. All these functions are modulated by dopamine and strategies aimed at improving dopaminergic function are used frequently to resolve residual symptoms of bipolar depression. It is expected that aripiprazole used at a more adequate lower dose than in previous studies, should be efficacious in the treatment of bipolar type I depression.

The primary goal of this study is to examine the triglyceride/HDL ratio and the ischemic EKG changes in patients with schizophrenia, schizoaffective disorder or bipolar disorder.

The Canadian Rapid Treatment Center of Excellence (CRTCE) is a healthcare facility principally focused on providing best practices of intravenous ketamine treatment to adult patients suffering from mental health conditions. The center focuses specifically on treating individuals suffering from major depression disorder, bipolar disorder, post-traumatic stress disorder and obsessive compulsive disorder as their primary diagnosis. Herein, this retrospective analysis aims to look at past data in order to further develop our understanding of ketamine in the use of psychiatry.

The COVID-19 pandemic significantly impacted primary care across Canada. Inequities in prevention activities and chronic disease management likely increased but the extent is unknown. Pragmatic interventions are required to prioritize patients and improve the quality of primary care post-COVID. In AFTERMATH, the investigators will conduct a pragmatic cluster randomized controlled trial (cRCT) at the largest primary care Practice-Based Research Network (PBRN) in Ontario, focused on a highly marginalized population: adults living with mental illness and one or more additional chronic diseases. The investigators will test an intervention that builds on the investigators' past work and combines data and supports to primary care providers to improve quality of life, reduce gaps in prevention activities and improve chronic disease management. The investigators' project will result in new evidence on ways to improve access to care and reduce inequities, and inform future efforts to use data beyond COVID-19.

Investigators will study approximately 64 patients with Treatment-Resistant Bipolar Depressive Disorder, defined as a failure of at least 1 antidepressants in the current depressive episode and 2 lifetime medication failures. The study will last approximately 6 to 8 weeks, involving randomization into one of two treatment groups receiving 3 one hour long inhalation treatments over a week.

This is a randomized, double blind, placebo controlled trial of the medication zonisamide for the purpose of reducing heavy drinking and drinking, as well as reducing mood symptoms, in bipolar subjects that drink excessively and heavily. Hypotheses: (Primary aims); Add-on zonisamide compared to placebo will result in: significant reduction in heavy drinking days, drinks per week and per drinking day, and significantly greater increase in abstinent days, ii) greater rates of abstinence and abstinence to heavy drinking, greater reduction in biomarkers of heavy alcohol use such as gamma-glutamyl transferase (GGT), and greater reduction in alcohol urge or "craving", Significant reduction in prevalent mood symptoms on the BRMS and BRMeS, CARS, HAMD, or no worsening of euthymic mood, and significant improvement on the Clinical Global Impressions Scale-Severity. (Secondary aims) Add-on zonisamide compared to placebo will result in significant reduction in weight (kilograms) and other secondary weight-related metabolic factors such as fasting glucose, lipid profile, and blood pressure. (Secondary aims) Add-on zonisamide compared to placebo will result in improved clinical global impression, overall functioning, quality of life, and reduced medical symptoms. 5.) (Exploratory Aims) To will examine interactions between genotype and medication on treatment response for allelic variation in genetic loci related to the major neurotransmitter and neurophysiologic pathways that are relevant to bipolar disorder, alcoholism, and zonisamide mechanism of action.

Bipolar Disorder show cyclic changes of mood between depression (depressive phase) and mania (maniac phase). Vestibular tests have been shown high sensibility and specificity as a biological marker for major depression. This exploratory investigation will measure and compare the vestibular activity of bipolar disorder patients during different phases ( 6 depressed phase, 6 maniac phase, 6 euthimic and 6 control healthy subjects).
