Abstract
OBJECTIVE
To assess the frequency and severity of cognitive impairment as well as its correlations with clinical characteristics in remitted patients with bipolar disorder (BD).
MATERIAL AND METHODS
Eighty-five patients with BD type I (64 patients) and BD type II (21 patients) in remission were examined (average age 36.6±5.7). Affective symptoms were assessed using the Hamilton Depression Rating Scale (HDRS) and Young's Mania Rating Scale (YMRS). Cognitive impairment was assessed using the Brief Neuropsychological Cognitive Examination (BNCE).
RESULTS
Cognitive impairment was revealed in 43.5% of the patients. The frequency and structure of cognitive impairment in patients with BD type I and type II did not differ. The patients with cognitive impairment were characterized by decreased speed of mental processes, decreased working memory and attention deficit. The correlation of the total BNCE score with the age of the patients, duration of the disease, total HDRS and YMRS scores was revealed.
CONCLUSION
The results demonstrate the affective nature of cognitive deficit in the patients. Cognitive impairment in remitted patients with BD is a significant therapeutic target.
