"Eating disorders, including anorexia and bulimia nervosa, are characterised by abnormal eating behaviour and typical psychopathological features, including fear of fatness, drive for thinness, and body image disturbance. In most patients, there is no detectable focal brain abnormality. Nonetheless, associations of anorexia and bulimia nervosa with history of perinatal complications and head injuries suggest a role of cerebral pathology in some cases. A number of case studies describe eating disorders with intracranial tumours, injuries, or epileptogenic foci. However, many clinical descriptions are limited to changes in appetite and lack psychopathological features characteristic of eating disorders. A previous review of 21 anorexia cases associated with brain tumours found that only three of them fulfilled formal diagnostic criteria. In the present paper, we provide a systematic review of published case reports and highlight those relatively rare cases where typical eating disorders appear to be causally associated with localised brain damage."
