Ketamine, TMS and ECT for Bipolar Depression
December 31, 2025 DOI: 10.64239/pi-vl10011
Summary
AI-generated from the abstractKetamine should be used cautiously in bipolar disorder because it can trigger psychosis, and is best limited to short-term (one-month) treatment of severe depression that might otherwise require hospitalization. Electroconvulsive therapy (ECT) and transcranial magnetic stimulation (TMS) are both effective for bipolar depression, but ECT works faster and is preferred for severe cases with psychotic features, with remission rates as high as 95%. For bipolar depression, TMS is more effective when patients arrive in a positive mental state; encouraging enjoyable activities in the hour before treatment can improve response.

Abstract
Ketamines should be used cautiously in bipolar disorder due to its potential to trigger psychosis, and is best reserved for short-term (one-month) treatment of severe depression that might otherwise require hospitalization. While both ECT and TMS are effective for bipolar depression, ECT acts faster and is preferred for more severe cases with psychotic features, with studies showing remission rates as high as 95%. For bipolar depression, TMS is more effective when patients arrive in a positive mental state; encourage enjoyable activities in the hour before treatment to get a better response.
