Active clinical trials for "Bipolar Disorder"

This twelve month, open-label study considers the effect of Risperdal (risperidone) versus Zyprexa (olanzapine) on weight gain, physical health, and outcome in a population of those diagnosed with schizophrenia, schizoaffective disorder, major depression or bipolar disorder with psychotic features. This study evaluates symptom response as well as general health indicators such as body mass index, glucose, prolactin, and cholesterol levels at baseline, month (M)1, M3, M6 and M12.

This study will evaluate a family intervention program for individuals with bipolar disorder, schizophrenia, or schizoaffective disorder and co-occurring substance use disorders.

The purpose of this research study is to confirm the safety and effectiveness of aripiprazole therapy over 12 weeks in subjects with bipolar disorder experiencing symptoms of mania.

The purpose of this study is to evaluate the effectiveness and tolerability of an investigational drug for the treatment of manic episodes of bipolar disorder. The investigational drug will be given as additional treatment with either lithium or valproate, which are already FDA (Food and Drug Administration)-approved treatments for mania.

The purpose of this study is to evaluate the effectiveness and tolerability of an investigational drug for the treatment of manic episodes of bipolar disorder. The investigational drug will be given as additional therapy to one of the five following medications: risperidone, olanzapine, quetiapine, ziprasidone, or aripiprazole. These medications are already FDA (Food and Drug Administration)-approved treatments for mania.

A long-term study of current treatments for bipolar disorder, including medications and psychosocial therapies.

This study will explore the possible effectiveness of levetiracetam in patients with bipolar illness who have not responded adequately to standard treatments. Levetiracetam was recently approved to treat seizures. Other drugs in the same class as levetiracetam, including carbamazepine and valproate, are widely recognized as substitute medications for lithium or are used as an adjunct to it, and other anticonvulsants have also shown promise in improving bipolar symptoms. Patients with bipolar illness whose manic, depressed or unstable moods are not adequately controlled by their current treatment and who have not responded previously to two standard treatments (i.e., lithium, valproate, carbamazepine or neuroleptics) may be eligible for this study. Participants will take levetiracetam starting at 500 mg daily. If this dose is well tolerated, it will be increased to 500 mg twice a day. Every 3 days, doses may be increased until the target dose of 3000 mg/day is reached. Higher doses, not to exceed 4000 mg/day, may be tried in patients who do not respond fully to the lower doses. Patients and observers will use standard ratings to evaluate the patients' response to therapy during the 8-week study. If, after 8 weeks, the results appear promising, patients may continue treatment for an additional 6 months to evaluate longer-term effects.

There is a scarcity of clinical trials assessing the effects of medications in children with bipolar disorder. This study aims to assess the efficacy of Aripiprazole (a novel anti-psychotic drug) for the treatment of children and adolescents with bipolar disorder comorbid with ADHD. The study design is a 8-week randomized, double blind, parallel group trial. Patients were randomized to either aripiprazole or placebo. The main hypotheses are: Aripiprazole will significantly reduce maniac scores compared to placebo Aripiprazole will significantly reduce ADHD scores compared to placebo

The purpose of this study is to evaluate the safety and effectiveness of clozapine as a treatment for the manic phase of bipolar disorder. A significant proportion of manic patients either do not respond adequately to conventional treatment or cannot tolerate the adverse effects associated with therapeutic doses of these agents. Clozapine may be a safe and effective treatment for mania. However, the efficacy of clozapine as an alternative therapy in treatment-resistant bipolar disorder mania has not been extensively researched. The study will be conducted in three phases. Phase 1 is a screening phase that will take place for 2 to 7 days. Participants will undergo a baseline positron emission tomography (PET) scan of the brain at the end of this period. In Phase 2, participants will be randomly assigned to receive either clozapine or placebo (an inactive pill) for 3 weeks. They may also receive lorazepam for the first 10 days of Phase 2. After 3 weeks, patients treated with clozapine will undergo a second PET scan. During Phase 3, participants who received placebo and did not improve will be offered clozapine for 3 weeks. Those who received clozapine and did not improve will receive other treatment for 3 weeks. At the end of Phase 3, participants who were treated with clozapine will have another PET scan.

The purpose of this study is to evaluate the safety and effectiveness of the drug felbamate for treating depression in patients with bipolar disorder that has not responded to standard treatments. Bipolar disorder is a severe, chronic, and often life-threatening illness. Despite the availability of a wide range of antidepressant drugs, a proportion of patients fail to respond to first-line antidepressant treatment despite adequate dosage, duration, and compliance. Studies suggest that the glutamatergic system may play a role in the pathophysiology and treatment of depression. Felbamate and other agents which reduce glutamatergic neurotransmission may represent a novel class of antidepressants. Participants in this study will be admitted to the Clinical Center for up to 10 weeks. At study entry, participants will have a 7-day washout period in which they will be tapered off all psychiatric medications, with the possible exception of lithium, and will be given a placebo (an inactive pill). After the washout period, participants will be randomly assigned to receive either felbamate or placebo for 8 weeks. Participants whose depression symptoms worsen by more than 30% or those for whom study continuation is considered potentially harmful will be taken off the study and offered open-label treatment. Participants who received felbamate and responded well to treatment will have the option of continuing treatment.
