[Comorbidity of eating disorders and bipolar affective disorders].
Eating disorders--anorexia nervosa, bulimia nervosa and eating disorders not otherwise specified (EDNOS) occur usually in young females. The significant pathogenic differences between patients who only restrict food, and patients with binge eating and compensatory behaviours, such as vomiting and purging were described. The prevalence of bipolar affective disorders--especially bipolar II and bipolar spectrum disorders (BS) may reach 5% in the general population. About half of the depressive episodes are associated with a "mild" bipolar disorder, and such a diagnosis is suggested by impulsivity and mood-instability. Previously, majority of research on the comorbidity between eating and affective disorders focused on depressive symptomatology, however difficulties in the reliable assessment of hypomania may obfuscate the estimation of the co-occurrence of eating disorders with BS. Epidemiological studies suggest the association between BS and eating disorders with binge episodes (bulimia nervosa, anorexia- bulimic type and EDNOS with binge episodes). Co-occurrence of such disorders with depressive symptoms probably suggests the diagnosis of BS, not recurrent depression. Bulimic behaviours, impulsivity and affective disorders might be related to the impairment of the serotonergic neurotransmission, which may result from the genetic vulnerability and early life trauma. Currently, the first-line pharmacological treatment of co-occurring eating disorders with binge episodes and BS are selective serotonin reuptake inhibitors. However in some cases, the use of mood-stabilising agents as monotherapy or in combination with serotonergic drugs may be helpful.
