Transcranial magnetic stimulation and ketamine: implications for combined treatment in depression

Summary & key facts

This paper reviews research on using transcranial magnetic stimulation (TMS) together with ketamine to treat people whose depression does not improve with usual treatments. Both TMS and ketamine can lower depressive symptoms on their own. Some recent studies suggest that giving them together might create bigger or longer-lasting improvements. The review summarizes the existing studies, discusses possible brain mechanisms for combined effects, and highlights that more research is needed to work out the best ways to combine these treatments.

Key facts:

• The review focuses on treatment-resistant depression, which means depressive illness that does not respond to standard treatments.
• Both transcranial magnetic stimulation (TMS) and ketamine have been shown in studies to reduce the severity of depressive symptoms when used separately.
• Some recent studies report that combining TMS with ketamine can produce stronger and possibly longer-lasting reductions in depressive symptoms compared with each treatment alone.
• The paper is a review article: it summarizes and interprets existing studies rather than reporting a new clinical trial.
• The authors state that evidence is still emerging and that optimal combined treatment protocols (timing, dosing, stimulation parameters) are not yet established.

Abstract

Drug-resistant mental disorders, particularly treatment-resistant depression, pose a significant medical and social problem. To address this challenge, modern psychiatry is constantly exploring the use of novel treatment methods, including biological treatments, such as transcranial magnetic stimulation (TMS), and novel rapid-acting antidepressants, such as ketamine. While both TMS and ketamine demonstrate high effectiveness in reducing the severity of depressive symptoms, some patients still do not achieve the desired improvement. Recent literature suggests that combining these two methods may yield even stronger and longer-lasting results. This review aims to consolidate knowledge in this area and elucidate the potential mechanisms of action underlying the increased efficacy of combined treatment, which would provide a foundation for the development and optimization of future treatment protocols.
