Abstract

INTRODUCTION: The impairment of neurocognitive functioning in bipolar disorder is well-documented in the literature. Beside the acute phase of the illness, to a certain extent cognitive impairment can also be observed during euthymia, and there is an increasing number of search results reporting on alterations in the cognitive functioning of asymptomatic relatives of patients with bipolar disorder. All these suggest the role of neurocognitive functions as an endophenotypic marker of bipolar disorder.

METHODS: The purpose of this article was to review the existing studies conducted among first-degree relatives of patients with bipolar disorder that focused on the exploration of possible neurocognitive deficits.

RESULTS: One review, two meta-analyses and 43 studies met the search criteria. The results of the reviewed studies are inconsistent, both positive and negative results can be found among them. Those with positive results report on dysfunctions of different cognitive domains.

CONCLUSION: Overall, the available data suggest that neurocognitive functioning in first-degree relatives of bipolar patients is affected. To clarify the issue, further research is needed.
