Filter by:Theory of mind (TOM), a main component of social cognition processes, refers to the capacity to infer one's own and other person's mental states. Deficits in social cognition are found in patients with schizophrenia and bipolar disorder. The purpose of this study is to compare the neurofunctional profiles of schizophrenic patients, bipolar patients and healthy participants during the performance of a TOM task. Results may help to understand the neural bases of the impairments in social cognition in schizophrenia and bipolar disorder, which may in turn help to propose potential new psychosocial therapeutic approaches in these disorders.

Bipolar disorder (BD) is characterized by extreme changes in mood and emotion dysregulation. Mood changes are episodic in nature, with distinct periods of mania, depression, and asymptomatic periods of euthymia. In addition to impairments in mood, cognitive impairments are a common feature of the disorder. These cognitive impairments persist during periods of euthymia and are associated with negative clinical and psychosocial outcomes. Specifically, individuals with BD show impairments in executive functions. Recent studies show that emotion regulation can be down-regulated by taxing executive functions, and it can be improved with working memory training, a specific component of executive functions. These initial studies show that emotion regulation is under executive control in healthy individuals; however, the nature of this relationship is not well understood in populations that are affected by impairments in both executive control and emotion regulation. Previous work on cognitive training has not targeted specific cognitive domains with an emphasis on understanding the underlying mechanisms that promote change. Moreover, well-controlled randomized control trial (RCT) studies are needed in order to provide high quality evidence to inform the efficacy of cognitive training interventions for psychiatric populations. The aim of the proposed study is to use a commercially available cognitive training program to study the effects of working memory training on cognitive, clinical, and psychosocial outcomes in patients with BD. We hypothesize that training working memory will lead to improvements in cognitive and emotional functioning, leading to downstream changes that will positively impact untrained outcomes, such as mood and community functioning.
Bipolar disorder (BPD) is often misdiagnosed as unipolar depression. This leads to inadequate treatment and can have negative impact on the course of the disease. There is now preliminary evidence that patients with unipolar and bipolar depression as well as healthy individuals with a heightened risk of BPD can be distinguished from each other based on their brain activity patterns and functional connectivity during resting state. However, the impact of pharmacological treatment on these functional brain measures have not yet been clarified. For common antidepressants it has been shown that they seem to normalise aberrant brain activity patterns and functional connectivity. The problem is that some antidepressants can induce mania or accelerate pathological cycling in depressive patients with unrecognised BPD. Therefore, pharmacological drugs with mood-stabilising properties such as quetiapine are more and more prescribed. Although the effectiveness and tolerability have been proven, the neuronal effects of these adjunctive treatments are not clear. The aim of the study is thus to investigate the impact of quetiapine on measures of brain activity in depressive patients with a heightened risk of BPD. Moreover, the investigators want to examine whether the investigators can distinguish depressive patients with a heightened risk of BPD from depressive patients without a heightened risk of BPD using neuroimaging techniques, and whether these measures can predict the course of the disease.
Background: . Bipolar disorders and tobacco use disorder are top of the causes of disability and mortality worldwide Objective: The aim of this study was to evaluate N-acetyl-cysteine (NAC) as an adjunctive treatment in patients with bipolar .disorders and tobacco use disorder (TUD) , to determine whether NAC reduces alterations in biomarkers of inflammatory and oxidative stress Methods: This study will be conducted as a double-blind, randomized, placebo controlles add NAC or placebo for .bipolar disorders and tobacco use disorder at Londrina State University, Brazil.
This is a parallel 3-group, multicenter, prospective, randomized, single-blind (evaluator) controlled pilot trial, with a 38- week follow-up. Patients diagnosed with bipolar disorder (BD) according to DSM -5 criteria for mild depression or subsyndromal depressive symptoms are assigned to one of the following 3 treatment groups: 1) psychopharmacological treatment plus Mindfulness Based Cognitive Therapy (MBCT); 2) psychopharmacological treatment plus structured group psychoeducation; 3) treatment as usual (TAU), including standard psychiatric care with standard pharmacologic treatment.
The purpose of the study is to explore the effect of MPH on working memory, attention and decision making in adults with BD in remission or in depressed state. The results will be compared to findings in healthy adults and adults with ADHD. The investigators hypothesize that MPH will incur improved performance in all measures.
The purpose of this study is to evaluate whether repetitive transcranial magnetic stimulation (rTMS) treatment is an effective adjunct treatment to mood stabilizers and Bupropion.
