Comorbid conditions are frequent in Bipolar disorder (BD) and may complicate the treatment and course of illness.

Abstract

Comorbid conditions are frequent in Bipolar disorder (BD) and may complicate the treatment and course of illness. We investigated the role of Substance use disorder (SUD), axis II Personality disorders (PD) and continuous personality traits on the medium-term outcome (6 months) of treatment for bipolar depression. One-hundred and thirty-nine BD patients meeting criteria for a depressive episode were included in the study. Fifty-six patients were diagnosed for antecedent SUD and 61 for PD. Personality dimensions were evaluated by the Temperament and Character Inventory (TCI-R). Depressive severity over time was evaluated by the Hamilton Rating Scales for Depression (HAMD). Neither PD nor SUD influenced the outcome of depression, though relapse in SUD was concurrent with a slight worsening of depressive symptoms. Variables independently associated with a poor outcome were a high baseline severity and high scores at the temperamental trait of Harm avoidance. Results did not confirm SUD and PD as complicating factors for the medium-term treatment of depression in BD patients. Though several limitations characterize the present study, neurotic personality traits are supposed to be associated with a slower recovery from depressive symptoms in BD, independently from their initial severity.
