Electroconvulsive Therapy: Safety and Efficacy Above Age 75 Years

Introduction: Electroconvulsive Therapy (ECT) is a type of brain stimulation therapy used to treat a variety of mental illnesses. ECT is used most commonly to treat severe depression, especially when other treatments have not worked. The safety of electroconvulsive therapy in patients over the age of 75 has been questioned by several American studies, which have reported high complication rates in this age group. Aim and Objectives: To study the safety and efficacy of electroconvulsive therapy in patients over the age of 75 years. Methodology: Retrospective study of all patients over 75 years treated with ECT in three hospitals between January 2014 and December 2016 for a period of 3 years. The Treatment Intensity Scale was used to rate the adequacy of the anti depressant treatment if the index episode. The complication rate was determined by review of medical and nursing notes. Results: A total of 103 ECT courses were administered during the study period. Ten patients (9.71%) suffered complications following ECT. The most common adverse events were prolonged confusion and hypomania, all of which resolved within 2 weeks of the cessation of treatment. Eighty five per cent of patients made a marked or moderate response to treatment. Conclusions: ECT is a very safe treatment and doesn’t cause brain damage or changes in personality because the amount of electricity used is too small. ECT is a relatively safe and effective procedure in patients over age 75.
