title: [Neuroprogression and cognition in Bipolar Disorders: A systematic review of cognitive performance in euthymic patients].
abstract: In recent years, investigators have begun to consider the possibility of explaining the physiopathology of bipolar disorder from a neuroprogressive perspective. The evidence that supports the feasibility of such an approach is varied, and arises from neuroimaging studies, batteries of neurocognitive evaluations, and tests to identify the specific biomarkers of the disorder. The present article seeks to perform a review of the research that investigates the cognitive deficits in bipolar disorder. A bibliographic revision was performed of articles published between 1990 and 2015. Levels of cognitive performance were explored in both cross-sectional and longitudinal studies. The compiled studies signal the presence of altered cognitive function, even during periods of euthymia. However, there are contradictory results as to whether bipolar disorder presents a degenerative course. New lines of investigation suggest that only a percentage of individuals with bipolar disorder are affected in a progressive manner. It is of paramount importance to perform new longitudinal studies in high-risk populations, so as to validate or refute a neuroprogressive model of cognitive deficits in patients with bipolar disorder.
