Abstract
OBJECTIVE: To assess the association between sub-types of bipolar disorder (BD) (types I and II) and sub-types of eating disorders (EDs) (Anorexia Nervosa, Bulimia Nervosa, Binge-eating disorders) as well as their relative order of occurrence. METHODOLOGY: A systematic review of articles estimating prevalence rates for BD among patients with ED and vice versa. We also analysed all articles assessing their relative order of occurrence. RESULTS: Comorbid BD is common among patients with an ED. From 0.6 to 33.3% of bipolar subjects have an eating disorder. Conversely, from 0 to 35.8% of subjects with an ED can present a BD. This co-occurrence has mostly been observed among patients with anorexia of the bulimic/purging type, with bulimia or with binge-eating disorders. The association is less frequent in cases of anorexia of the restrictive type. In contrast, the BD sub-type does not seem to have an impact on the association with EDs. Whilst age at BD onset is earlier in case of a comorbid ED, age at ED onset does not seem to be impacted by the presence of an associated BD. There has been little data on the relative order of occurrence of the two disorders or on the impact of the thymic phase on the expression of EDs. CONCLUSIONS: EDs and BD are frequently comorbid, suggesting the need for crossed screening of these pathologies, in particular for EDs with purging behaviours and for patients with early BD onset.
