A Trial of Cognitive Training in Euthymic Bipolar Disorder

Status Not yet recruiting

Clinical Trial Summary

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.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
