Active clinical trials for "Mental Disorders"

The purpose of this study is to compare the effectiveness of divalproex sodium (Depakote) versus placebo in treating disruptive behavior disorder and explosive tempers in adolescents and adults.

The purpose of this study is to determine the effects of psychoeducation for relatives to patients with serious mental illness.

This study evaluates the safety and tolerability of Asenapine in elderly patients with psychosis.

Ketamine, an FDA approved anesthetic agent, is becoming the sedative/analgesic of choice for emergency sedation in children because it causes deep sedation with minimal respiratory depression in comparison to other available agents. However, emergence reactions are an important adverse effect of ketamine, characterized by transient changes in cognitive function, dissociation and mild schizophrenia-like symptoms. These cognitive and behavioral effects are dose-dependently induced by ketamine and other antagonists of the N-methyl-D-aspartate (NMDA) glutamate receptor. NMDA receptor hypofunction can disinhibit excitatory (cholinergic/glutamatergic) projections in key areas of the brain, and this has been proposed to explain key features of schizophrenia. Several treatments that block excessive excitatory transmitter release have also been shown to prevent cognitive and behavioral effects of ketamine-induced NMDA receptor hypofunction in humans. Alpha-2 adrenergic agonists, which can presynaptically inhibit acetylcholine release, can prevent mild ketamine-induced behavioral and cognitive symptoms in healthy human adults. However, this prevention strategy has not been evaluated in children. Children currently receive clinically-indicated treatment with the NMDA antagonist, ketamine, and this age group is an important target for pharmacological strategies aimed at the prevention of schizophrenia. This application proposes a double-blind, placebo-controlled, randomized trial to test the safety and effectiveness of dexmedetomidine, an FDA approved alpha-2 adrenergic agonist, in preventing ketamine-induced mental symptoms in children. Planned primary analyses will evaluate effects of the hypothesized prevention treatment on clinical and cognitive variables using analysis of variance (ANOVA). The proposed experiments are relevant to future prevention trials for individuals at risk for schizophrenia, and to preventing adverse effects of NMDA antagonist anesthetic agents (ketamine, nitrous oxide).

Corlux (mifepristone) is a new medication that modulates the body's use of a hormone called cortisol. Under normal conditions, cortisol and other hormones are created by the body in response to physical and emotional stress, triggering a healthy stress response. People who suffer from psychotic major depression may have unusually high levels of cortisol circulating within them or abnormal patterns of cortisol levels, overloading the stress response mechanism and causing symptoms of psychosis such as delusional thoughts or hallucinations. If Corlux can keep the body's cortisol receptors from being overloaded, the stress response system may return to normal function, which may result in improvement of symptoms. The purpose of this study is to allow patients who have already participated in an earlier 8 week study of Corlux versus placebo (an inactive pill) to receive additional courses of treatment with Corlux periodically if a psychotic episode should reappear during a period of one year.

This study investigates the neuroprotective properties of low-dose lithium in young individuals at ultra-high risk of developping a first psychotic episode. Fourty individuals having some symptoms of an emerging psychotic disorders (without meeting the threshold for a full-blown mental illness) will be treated with a low dose of lithium (about a third of the dose that is usually used to treat acute mania). We will assess the progression of the conditions of these individuals on a montly bases for a year. We will do behavioural, cognitive and imaging assessments prior start of the treatment, after three months and one year. We hope to demonstrate that low dose lithium will stop or even reverse the progression of disease. We expect that behavioral, cognitive and in vivo brain imaging parameters in those individuals treated with low dose lithium improve, compared to the monitoring group.

The purpose of this study is to evaluate the efficacy of homeopathic treatment in pregnant women with overweight and class I obesity with suspicion of a mental disorder.

The primary purpose of the study is to assess the efficacy of Quetiapine extended release 600mg per day either as monotherapy or combined therapy in the treatment of patients with mania associated to Bipolar disorder. This trial will also assess the life quality and productivity loss improvement for patients from baseline to day 21.

The purpose of this study is to examine whether an intensive computerized intervention targeted on improving central auditory and visual processing and executive functioning can be implemented in youths aged 10-19 with psychotic spectrum disorders, what developmental modifications are needed particularly for the younger participants, and whether it is possible to develop an appropriate, blinded control intervention.

The purpose of this study is to determine the safety and efficacy of sustained-release quetiapine fumarate (Seroquel®) in the treatment of patients with Acute Bipolar Depression for 8 weeks. PLEASE NOTE: Seroquel SR and Seroquel XR refer to the same formulation. The SR designation was changed to XR after consultation with FDA.
