Cognitive, physiological, and personality correlates of recurrence of depression

Background sk of recurrence in depressive disorder is high and increases with the number of episodes. We investigated whether individuals with a history of recurrent depression deviate from individuals with a single episode, as regards risk-related variables in 3 different domains of depression research. s ipants were 102 outpatients with major depressive disorder remitted from an episode (60 recurrent, 42 nonrecurrent). We assessed the perception of emotions from vocal stimuli, 24-h urinary free cortisol, and neuroticism. s current group had higher cortisol levels than the nonrecurrent group, and recurrent women also had a more negative perception than nonrecurrent women. These results were independent of each other, and could also not be accounted for by neuroticism or residual symptoms. Gender differences were found in all 3 domains. tions oss-sectional design limits the possibility to draw conclusions on the causality of the observed effects. sions ed outpatients with recurrent depression deviate from remitted outpatients with single episode depression as regards physiology and social cognition, in a way that may increase their risk of the development of subsequent episodes. The results may have implications for prophylactic treatment strategies.
