Filter by:Serotonin (5-HT) is important in mood regulation and is believed to play a major role in the pathophysiology of major depression (MD). Selective serotonin reuptake inhibitors (SSRIs) are currently the most widely used drugs for the treatment of depression. Patients with bipolar disorder (BD) who are treated for depression with SSRIs might develop mania, which is believed to be triggered by antidepressant treatment. Rapid tryptophan depletion (RTD) has been shown to induce transient depressive symptoms in remitted depressed patients treated with SSRIs. In remitted manic patients treated with lithium, RTD does not seem to have clinical effects. However, RTD was not studied in acutely manic patients and could theoretically have antimanic properties. In this double blind randomized placebo controlled study RTD will be used as a tool to assess the role of 5-HT in mania and will be evaluated for its antimanic properties and potential use as augmentation to drug treatment in acute mania.
This is a randomized, parallel, open-label study of patients who have responded to treatment in the acute phase of their manic or mixed episode, with or without psychotic symptoms, with olanzapine in mono or co-therapy, and who are in syndromic and symptomatic remission at the time of enrollment into the study.
The primary objective of this study is to assess the efficacy of olanzapine and fluoxetine combined on all the visits as compared with the baseline visit in patients with bipolar disorder, measured by the total score of the Montgomery-Asberg Depression Rating Scale (MADRS).
This trial will assess any efficacious benefit and any safety issues associated with the concomitant use of olanzapine and carbamazepine for the treatment of patients with bipolar I disorder, manic or mixed episodes
The primary objective of this study is to assess the efficacy of venlafaxine XR and lamotrigine when each is added to mood stabilizer therapy in patients with acute depressive episodes of bipolar I or Bipolar II disorder. Efficacy of therapy will be evaluated using improvements in clinical symptomatology after 8 weeks of treatment as measured by reductions on the Hamilton Depression Rating Scale (HDRS-29) total score >50% from baseline. We also would like to assess the efficacy of venlafaxine XR and lamotrigine when each is added to mood stabilizer therapy in improving clinical symptomatology after 8 weeks of therapy as well as to evaluate the side effect profile, safety and tolerability of venlafaxine XR and lamotrigine.
To compare antidepressant efficacy of left or right to sham Repetitive Transcranial Magnetic Stimulation (rTMS) to determine if non-responders can become responders if treated on the other side of the hemisphere (rTMS)
We hope to learn whether this stimulation of neurons in the front part of the brain may relieve depression.
The purpose of this study is to examine the safety and efficacy of Depakote ER in bipolar depression and to evaluate metabolic and GABA changes with Depakote ER administration using PET and MRI/MRS brain imaging techniques.
We will assess the effect of olanzapine compared to placebo added to prior treatment on CGI-S in a one-week randomized double-blind study. We will also assess the effect of olanzapine added to prior treatment on CGI-S in an eight-week open treatment study. In addition, we will assess the effect of olanzapine on Young Mania Rating Scale (YMRS), Hamilton and Montgomery-Asberg Depression Rating Scales (HDRS, and MADRS), and Hamilton Anxiety Rating Scales (HARS) in the above paradigms. We will also assess the influence of presentation severity (CGI-S) and polarity (mood elevation versus depression) on olanzapine response. Finally, we will assess safety and tolerability of olanzapine in the above paradigms. We hypothesize that in diverse mild syndromal and subsyndromal exacerbations of BD in outpatients, randomized double-blind flexibly dosed olanzapine added to prior treatment (including no treatment) will yield greater CGI-S improvement than placebo by the end of one week, and that such improvement will persist over one week of open continuation treatment.
The study is based on a hypothesis that there is interaction between the activity in the immune system and in the mind. To study this, the investigators register different measures for activity in the immune system on patients unselectedly admitted to an acute psychiatric ward. The psychiatric statuses and diagnoses of these patients are carefully defined as well.
