INTRODUCTION: Bipolar disorder causes substantial morbidity including cognitive impairment. The objective of the study was to evaluate memory performance of acutely mania bipolar I disorder (BD-I) patients with and without psychosis. We also aimed to assess the mood congruence phenomenon upon memory.
METHODS: A cross-sectional study was developed with BD-I patients (19 with, and 12 without psychotic symptoms), and 27 age- and education-paired healthy controls. Memory tests were selected to evaluate memory/attention performance. A verbal episodic memory task with affective content (word span) was also applied.
RESULTS: A significant difference was observed in the scores of the word span task with positive tone among the three groups, controlling for number of mania episodes (p=.042). Nonpsychotic BD patients presented higher scores. There was a statistical tendency for BD-I patients with and without psychotic symptoms to perform poorer than healthy controls in the delayed recall of the logical memory test (p=.069).
CONCLUSION: Psychotic and nonpsychotic mania BD-I patients showed mood congruence phenomenon in a verbal memory task with positive tone in relation to the healthy group. Evidence of mood congruence was found in the nonpsychotic group suggesting a purer manifestation of the disease.
