Filter by:The purpose of this study is to assess adolescents with Insulin Resistance Syndrome for quality of life and altered health related issues.
The purpose of this study is to determine whether treatment with AZD6765 will have an antidepressant effect with patients who have treatment resistant depression.
Mixed states in bipolar disorder have long been recognized. Over a century ago, it was argued that mixed states were the most common episodes in manic-depressive illness. A mixed state is defined as a person who is experiencing symptoms of both depression and mania. Currently, a person must have depression plus 3 or more manic symptoms for the episode to be diagnosed mixed. Using this narrow view, less than 10% of episodes in patients with bipolar disorder would meet criteria for a mixed episode. A broader view requires that the person have at least 2 manic symptoms. Using this broader view, data suggest that about 50% of episodes in bipolar disorder would be diagnosable as mixed states. Studies suggest that the majority of persons with a depressive mixed state have bipolar disorder type II. Many people who have a mixed state will also have major depression. Even with such high potential rates of mixed episodes in both bipolar disorder and major depression, there have been few studies addressing the issue. The purpose of this study is to look at how effective Geodon is in treating the depressive mixed state in people with bipolar or major depression. This will be the first clinical trial that is both double-blind and randomized.
To determine if duloxetine works just as well as paroxetine in the treatment of major depressive disorder.
The study is to show the new salt formulation of GSK372475 is equivalent to the old salt formulation of GSK372475.
The study aim is to explore the effect of a comprehensive Internet-based disease management program for bipolar disorder and recurrent or chronic major depression on clinical outcomes and satisfaction with care.
The purpose of this study is to determine if a treatment regimen of ziprasidone plus a mood stabilizer is safe and effective in the short term treatment of Bipolar I Depression. Ziprasidone will be added to lithium, valproate or lamotrigine after the patient has been on a therapeutic dose of one of these mood stabilizers for at least 4 weeks.
The purpose of this study is to see if transcranial direct current stimulation may improve the symptoms of depression.
The primary objective of the study is to determine if armodafinil treatment, at a dosage of 150 mg/day, is more effective than placebo treatment as adjunctive therapy for adults who are experiencing a major depressive episode associated with Bipolar I Disorder and who are inadequately responsive to their current treatment for a current major depressive episode.
The project will investigate the use of a novel technique, transcranial direct current stimulation (tDCS) in the treatment of patients with schizophrenia and patients with depression. tDCS involves the application of an extremely weak continuous electrical current to the brain through the placement of anode and a cathode on the scalp. The electrical current is generally completely imperceptible after initial period of tingling which takes about 30 seconds. Stimulation under the anode appears to increase brain activity where as stimulation under the cathode has the opposite effect. This research plan involves two clinical trials: 1. A study using tDCS to treat both the positive and negative symptoms of schizophrenia. The negative symptoms of schizophrenia such as lack of motivation and energy appear to arise due to a lack of activity in frontal brain areas. Positive symptoms such as hallucinations and confused thoughts may arise through over activity of brain areas more on the side and towards the back of the brain called the temporal cortex. We plan to apply tDCS such that it can simultaneously increased activity in these frontal brain areas and reduce activity over temporal cortex. We will compare active stimulation to a placebo condition which involves turning the stimulator off after 30 seconds. The capacity to target multiple symptom clusters is unique with this type of brain stimulation. 2. The study using tDCS in treatment resistant depression builds on a work with transcranial magnetic stimulation (TMS). TMS techniques in depression seem to work which increased left frontal brain activity or decrease right frontal brain activity. tDCS will be used to do the same thing with the anode used to increase left-sided brain activity and the cathode used to simultaneously decreased right-sided brain activity. tDCS is potentially a better tolerated procedure than TMS and does not appear to have the same risk of seizure induction. Importantly, the equipment is quite inexpensive and this may prove to be an extremely safe and effective low-cost treatment for psychiatric disorders in Third World countries.
