[en] P300 and contingent negative variation (CNV) were recorded in depressive inpatients with and without history of suicide attempt. The results show a significant reduction of both P300 and CNV in patients who had attempted suicide as compared with patients who had not. Moreover, a significant correlation was found between the suicidal risk scale and CNV amplitude. Psychophysiological and biochemical implications are discussed.
