Abstract:

The importance of gender on phenomenology and course of bipolar illness has been an increased focus of study over recent years. The purpose of present study was to examine whether gender differences exist in the sociodemographic characterictics, age of onset, severity of disease, number & type of episodes, symptomatology and treatment response of bipolar disorder. The life charts of 300 (193 female; 107 male) patients with BD type-I were evaluated retrospectively. BD diagnosis of patients was given by two experienced clinicians in accordance with DSM-IV-TR criteria. A semi-structured chart which was developed to assess sociodemographic and clinical features of patients and “mirror design” method was utilized for the assessment of patients’ response patterns to maintenance treatment. Bipolar women were significantly more likely to have history of (at least one) any mood episode than bipolar men. However no significant gender differences emerged in number of manic or mix episodes; whereas, women had more depressive episodes. Frequency of psychotic episodes (at least one episode during lifetime) was higher for men than women.. There was also no significant gender difference in terms of response to lithium and anticonvulsant maintenance treatment, mean episode severity and age of onset. The results of the present study show that some gender differences may be evident in patients with BD-I. In the highlight of that investigators studying bipolar disorder may need to consider gender as a variable for assessment and treatment strategies.
