Filter by:This study is being done to look at how well people respond to two very different drug treatments for depression. Clinically, people with depression can respond differently to drug treatments for reasons which are not always clear. Some of our own recent research suggests that people with depression who have a family history of bipolar disorder or completed suicide, may react differently to standard antidepressant medications than those without such a family history. Our data shows that family history of completed suicide, as well as the known predictor of family history of bipolar disorder, may help identify a pre-bipolar high risk group i.e. they currently have depression but at some future date will declare a bipolar illness (manic-depression) by virtue of development of a manic episode also. Our research suggests that treatment- emergent symptoms in response to a trial of antidepressant, such as agitation may be strong predictors of future bipolarity and inherently dangerous particularly as they are not ascribed to the antidepressant treatment. Finally, it is possible that this subgroup of those with depressive illness may respond better and more safely to lithium, a mood stabiliser used in known bipolar depression. The objective of this proposal is to investigate response to acute lithium treatment in subjects who meet the diagnostic criteria for major depression, but who are potentially at risk for bipolar disorder, by virtue of family history of bipolarity or completed suicide.
This study was developed in order to assess the effects of risperidone (Risperdal) as compared with placebo on cognitive-motor performance (attention, memory, and hand steadiness) and body movements. We propose to study the effects of risperidone on cognitive-motor performance in children already medicated for severe conduct problems. We would also like to look at safety by assessing these children for dyskinetic movements. We already have a sizable cohort of children maintained on risperidone. Our hypotheses are as follows: 1. Risperidone will have no adverse effects on cognitive-motor performance in children who have received maintenance therapy for 4 to 20 months. 2. Children tested during placebo will show no more dyskinetic movements than during risperidone treatment (i.e., there will be no unmasking of tardive dyskinesia).
Some people with bipolar disorder who use cannabis (marijuana) claim that it eases the symptoms of depression and mania. There are many chemicals (called cannabinoids) found in cannabis but two particular ones appear to have medicinal (therapeutic) effects. These two compounds are: delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD). These cannabinoids appear to have mood, anxiety, and sedative effects as well as have antipsychotic and anticonvulsant properties. This study will try to find out if these cannabinoids can be of benefit as an add-on treatment in bipolar disorder and what effects it has on thinking power and memory.
The primary objective of this study is to compare the efficacy and tolerability of quetiapine versus divalproex extended-release administered in a rapid oral loading fashion in the treatment of acute episodes of mania or mixed mania in bipolar disorder. Three hypotheses will be tested: Hypothesis 1: treatment ( 3 weeks) of divalproex extended-release is similar to quetiapine in the symptomatic control of mania or mixed mania Hypothesis 2: divalproex extended-release orally loaded may produce significant improvements in symptoms of mania sooner than quetiapine Hypothesis 3: divalproex extended-release may produce significantly less sedation
The primary objective of this study is to examine the efficacy of topiramate in combination with olanzapine for the prevention of weight gain in youth with bipolar disorder. The secondary objective is to examine the tolerability of topiramate in combination with olanzapine for the prevention of weight gain in youth with bipolar disorder.
The objectives of this study are to determine whether this treatment may be useful for reducing cannabis consumption; reducing symptoms of bipolar mania; and weight mitigation therapy for individuals on psychopharmacotherapy.
The aim of this study is to evaluate the effectiveness, safety, and tolerability of metformin treatment in children and adolescents suffering from weight gain secondary to use of atypical antipsychotic medications. In this 12 week, open-label study we will investigate metformin's effects on weight control and/or weight loss. We hypothesize that metformin would prevent further weight gain or lead to weight loss, resulting in amelioration of one of the most significant side effects of atypical antipsychotic use.
Fourteen subjects with bipolar disorder and 14 matching healthy controls, aged 6-13, will receive a magnetic resonance imaging (MRI) scan on a 3 Tesla scanner. They will also have a clinical interview, including the KSADS-PL. All subjects must be right-handed.
The purpose of this randomized, double blind, double dummy, multicenter study was to evaluate the efficacy of risperidone long-acting injectable (LAI) monotherapy in comparison with placebo in the prevention of a mood episode in treatment of patients with bipolar I disorder. Oral olanzapine was used to assess the validity of the study design. The primary objective of this study is to evaluate the efficacy of risperidone LAI versus placebo in the prevention of a mood episode (recurrence event) in patients with bipolar I disorder after a 12-week (3 month) stabilization period on risperidone LAI, as measured by the time to recurrence of any mood episode. Risperidone LAI has been approved by the FDA in the USA for the treatment of patients with schizophrenia and for the prevention of mood recurrences in bipolar I disorder, as monotherapy or add-on treatment. It is approved at EMEA and other European and non-European health authorities for the treatment of patients with schizophrenia, too.
Recently, McLean hospital conducted a 4 month taurine study which showed a reduction in mania ratings. As a follow-up to the preliminary taurine study, and complementary to the currently ongoing double-blind, placebo-controlled trial for taurine in adults with bipolar disorder, this study will target adolescent bipolar subjects (type I) with symptoms of mania or mixed mania. To our knowledge, this would be the first study to evaluate the effects of the novel compound taurine in adolescent subjects with bipolar disorder. We hypothesize there will be a positive response in some adolescents from taurine treatment, and this positive response will be greater than that expected by chance. This study may demonstrate that taurine is a well-tolerated and effective adjunct treatment for mania in bipolar disorder.
