Objective. We present three cases of elderly women with comorbid severe mental disorders and somatic illnesses, successfully treated with electroconvulsive therapy (ECT).
Case reports. The following cases are discussed: (1) A 78-year-old woman with catatonia and comorbid diabetes, arterial hypertension, atrial fibrillation, endometrial hyperplasia with bleeding, experiencing a state after brain stroke; (2) A 67-year-old woman with catatonia developed after discontinuation of clozapine treatment, refractory to various neuroleptics. Her comorbid somatic conditions included enormous obesity, telescopic fracture of two thoracic vertebraes and chronic urinary tract infection; (3) A 69-year-old woman with profound mental retardation and long-term behaviour disorders involving aggression and self-injuries, refractory to various psychotropic medications. Her comorbid somatic disease was diabetes. In all these cases a good response was obtained to ECT treatment, without any serious adverse events.
Commentary. Comorbidity of psychiatric and somatic diseases in these patients resulted in life-threatening conditions that required ECT. The treatment was effective and with no adverse side effects.
