Abstract
Introduction. It has recently been observed that some cognitive deficits in bipolar disorders persist even after the subsidence of active symptoms. The authors aim to study the cognitive functioning of patients with bipolar disorder, currently in euthymia and compare them with normal healthy controls.
Methods. Fifteen patients having bipolar-I disorder and currently in euthymia were compared with fifteen age- and education-matched controlled subjects. Cognitive assessments were done using three computer-based tests, i.e., Wisconsin's Card Sorting Test (WCST), Spatial Working Memory Test (SWMT), and Continuous Performance Test (CPT).
Results. Euthymic bipolar patients showed significant deficits in executive functions. Subtle deficits were present in attention and working memory that were not statistically significant.
Conclusions. Executive deficits may be trait markers in bipolar disorder and may have clinical implications in patient rehabilitation.
