[Results of electroconvulsive therapy in restrictive indications. A retrospective study of 15 years].

In Tübingen ECT is restricted to severely ill patients who do not respond to other somatic therapies; especially to patients with endogenous depression and pernicious catatonia. Between 1976 and 1990, 45 patients were treated with ECT, of whom 22 suffered from endogenous depression and 10 from pernicious catatonia. Thirteen patients with other diagnoses (schizophrenic and schizoaffective psychoses, borderline schizophrenia and obsessive-compulsive disorder) were treated with ECT for severe depressive states after failure of psychopharmacological therapy. A positive therapeutic response to ECT was observed in 46% of patients with endogenous depression and in all 10 with pernicious catatonia. In the patients with schizophrenia and schizoaffective psychosis, borderline schizophrenia and obsessive-compulsive disorder, an amelioration of the depressive or anxiety syndrome was observed only in individual cases. Side effects of ECT were transit syndromes (20%), reversible amnestic syndromes (20%) and cardiac arrhythmias (6%). According to our results, ECT is highly effective in therapy-resistant endogenous depression and pernicious catatonia, and therefore remains a necessary part of psychiatric therapy.
