Objectives. Prevalence of two types of symptoms was assessed in the study: firstly, of bipolar spectrum disorders among female patients hospitalized for eating disorders, and secondly, of eating disorders in female patients with bipolar affective disorders.
Methods. Participants in the study were 98patients diagnosed with eating disorders, 48 with bipolar affective disorders, and 113 healthy women as controls. The Mood Disorder Questionnaire and Eating Attitude Test (EAT-26) were used for the assessment of bipolar spectrum and eating disorders symptoms, respectively.
Results. The prevalence of bipolar spectrum symptoms was significantly higher in patients with eating disorders than in the healthy controls. In patients with bulimia and the bulimic type of anorexia nervosa bipolar spectrum symptoms were significantly more frequent than in those with the restrictive type anorexia. In patients with bipolar affective disorders symptoms of eating disorders were found more often than in the healthy controls.
Conclusions. Eating disorders with binge episodes show a high comorbidity with the bipolar spectrum disorders. This may suggest a common pathogenic and temperamental background of both the disorders.
