Brain-derived neurotrophic factor (BDNF) plays a central role in synaptic plasticity and neurogenesis. Bipolar disorder (BD) is among the most disabling of all psychiatric disorders and is associated with poor outcomes. Some studies suggest that BDNF levels decrease during mood states and remain normal during euthymia, but other studies have contradicted(More)
Current literature on the effects of chronic stress in general health converges to the concept of allostatic load (AL). AL is the bodily 'wear and tear' that emerges with sustained allostatic states. In the field of bipolar disorder (BD), AL offers an important clue as to why patients who undergo recurrent mood episodes are clinically perceived as less(More)
OBJECTIVE Bipolar disorder (BD) is associated with significant morbidity and mortality due to comorbid general medical conditions, particularly cardiovascular disease. This study is the first report of the Brazilian Research Network in Bipolar Disorder (BRN-BD) that aims to evaluate the prevalence and clinical correlates of cardiovascular risk factors among(More)
BACKGROUND Glutamate deregulation may be involved in the neuropathology of schizophrenia, mainly through N-methyl-d-aspartate (NMDA) receptor dysfunction. Memantine, a drug approved by the FDA for the treatment of moderate to severe Alzheimer's disease, acts as a weak nonselective NMDA receptor antagonist. The aim of this study was to examine the efficacy(More)
UNLABELLED There is an increasing body of evidence suggesting that oxidative stress may play a role in the pathophysiology of both schizophrenia (SZ) and bipolar disorder (BD). METHODS We compared the antioxidant enzyme, serum superoxide dismutase (SOD) and the lipid peroxidation product, thiobarbituric acid reactive substances (TBARS) as assessed in(More)
OBJECTIVE There is an emerging body of data suggesting that oxidative stress may be associated with the pathophysiology of bipolar disorder (BD). In the present study we investigated the oxidative stress profile in two monozygotic twins during a manic episode. METHODS Two monozygotic twins diagnosed as currently manic by the Structured Clinical Interview(More)
UNLABELLED Gomes FA, Kauer-Sant'Anna M, Magalhães PV, Jacka FN, Dodd S, Gama CS, Cunha Â, Berk M, Kapczinski F. Obesity is associated with previous suicide attempts in bipolar disorder. OBJECTIVE There is a paucity of data about risk factors for suicide attempts in bipolar disorder. The aim of this study is to examine the association between suicide(More)
There has been an increasing interest in the role of the immune and inflammatory systems in mood disorders. Mood episodes are associated with changes in acute phase proteins such as high-sensitivity C-reactive protein (hsCRP). The present study investigated serum hsCRP in manic, depressed, and euthymic BD patients as compared to matched healthy controls.(More)
OBJECTIVE To verify and classify, according to the JNC 7, the blood pressure levels (BPL) of the employees of University of Brasilia, a public university in Brazil, who are older than 40 years of age, and to estimate the prevalence of cardiovascular risk factors in this population. METHODS A cross-sectional study was conducted at the University of(More)
