Filter by:There is sound evidence that quetiapine is effective in the treatment of manic and depressive episodes associated with Bipolar Disorder (BD) (Yatham et al 2006). However, even with the development of effective new treatment options, not all patients respond to treatments available. Biological markers have been investigated as predictors of response to treatment and of remission of symptoms. This would explain in part the individual's differences in the response to treatment, taking into account the genetic variability plus environmental factors influencing specific biological markers. A potential biological marker of response to treatment in BD would be the levels of neurotrophins, as they are, in fact, altered during acute mood episodes (Cunha et al 2006). Among neurotrophins, the Brain-Derived Neurotrophic Factor (BDNF) has been repeatedly and consistently reported to be associated with BD physiopathology (Post 2007). Furthermore, medications that are known to be effective in BD, like lithium and divalproex, increase BDNF levels.
One of the main challenges in the treatment of Bipolar Disorder (BD) is to achieve better functioning outcomes after syndromal recovery. Even treatment-responsive patients, who remain symptomatically well for extended periods of time, frequently demonstrate sub-threshold symptoms and continuing psychosocial morbidity and cognitive impairment. The cognitive impairment that persists during interepisode periods stands out as a major correlate of functional impairment, and may be a core aspect of the BD pathophysiology. In this context, tianeptine stands out as a therapeutic agent with unique properties, which match most of the conditions found in BD. This is an enriched maintenance study of the use of tianeptine as an adjunctive therapy in bipolar depression. All participants will receive tianeptine in an open label manner for a period of two months, following which they will be assigned randomly to the treatment with tianeptine or placebo in a double-blind fashion for six months. All patients will remain on treatment as usual for the duration of the trial. Along with clinical response, the investigators will prospectively evaluate the improvement in working and declarative memory, two cognitive prefrontal- and hippocampus-dependent processes, respectively, and the effects of tianeptine on serum BDNF levels.

This study investigates the effects of Lithium treatment on signal transduction pathways, gene expression and brain neurochemistry and structure in patients with Bipolar disorder. It is hypothesized that specific changes in these markers will correlate with lithium treatment responsiveness.
Among antidepressant treatments, Electroconvulsive therapy (ECT) stands as the most effective in treating acute depression. However, patient concerns with the cognitive side effects of ECT have encouraged the development of new and more focal forms of brain stimulation such as transcranial Direct Current Stimulation (tDCS). The investigators' current study of tDCS as a treatment for depression suggests that this technique has antidepressant effects and is safe, painless and well tolerated. However, not all patients may respond to this treatment and the concern of possible relapse in some patients who respond to tDCS has raised interest in finding treatments that may enhance and prolong the antidepressant effects of tDCS. This study will investigate whether D-Cycloserine, a medication shown to lengthen the effects of tDCS on brain activity, can also enhance/prolong the antidepressant effects of tDCS in people suffering from depression.
Very little is known about the impact of pregnancy and the postpartum period on BPD. As a result, the investigators have little evidence on which to base treatment guidelines. The main goal of this study is to help fill this gap by finding the risk factors for BPD relapse during pregnancy and the postpartum period. The risk factors that the investigators will study include: 1. the severity of illness in the past 2. the type and severity of both recent and past stressors 3. any treatments received during pregnancy and the postpartum period. Other goals of the study are: 1. to see what effect, if any, illness or any medicines taken during pregnancy have on the baby's well-being at delivery 2. to see how pregnancy alters the way the body clears any medicines taken for BPD 3. to see how much of these medicines babies are exposed to during pregnancy or breast-feeding. The investigators believe that the information gathered in this study will lead to new treatment guidelines for BPD during pregnancy and the postpartum period that will improve outcomes for pregnant women with BPD and their babies.
Prospective, open-label, controlled (active comparator), randomized study of 8 weeks follow-up for the evaluation of the efficacy of extended release quetiapine (quetiapine XR) versus Sertraline in addition to previous mood stabilizer treatment (lithium or valproate at stable and clinically therapeutic blood levels) in the treatment of the adult bipolar depression. This multicentric study will be featured in two sites in Spain.
The goal of the proposed clinical trial is to assess the effect of oral cytidine and omega-3 fatty acids (O3FA) on bipolar disorder symptoms. This study is a 4-month, randomized, parallel-group, double-blind, placebo-controlled pilot study of a combination of cytidine and omega-3 fatty acids in 90 recently ill subjects with bipolar disorder. During the 16 week period of the study, subjects are assigned to one of three groups: 1) omega-3 fatty acids + cytidine supplementation, 2) omega-3 fatty acids supplementation alone, and 3) placebo supplementation.
The purpose of this study is to understand the efficacy of light therapy for bipolar depression.
The purpose of this study is to evaluate the efficacy, safety, and tolerability of cariprazine in the treatment of outpatients with bipolar depression.
