title: Response to prophylactic lithium in bipolar disorder may be associated with a preservation of executive cognitive functions.
abstract: We assessed performance on the Wisconsin Card Sorting Test (WCST), measuring executive functions, in 30 patients showing different prophylactic effect of lithium (excellent lithium responders-ER, partial responders-PR and non-responders-NR), and in fifty persons of their offspring (12 of ER, 26 of PR, and 12 of NR). Age- and gender head-to-head matched population consisted of 30 subjects for lithium group and 50 subjects for the offspring of lithium patients. In lithium patients, NR had significantly worse results compared to the remaining groups and to control subjects on perseverative errors (WCST-P) and conceptual responses (WCST-%conc). No differences were observed in the offspring of patients with different effect of lithium, however, they showed an impairment on WCST-P and WCST-%conc compared to matched healthy controls. Therefore, the favorable effect of lithium prophylaxis may be associated with a preservation of executive cognitive functions and the offspring of bipolar patients shows an impairment of such functions.
