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

Summary & key facts

This paper is a review that looks at studies using two treatments for hard-to-treat depression: transcranial magnetic stimulation, which uses magnets on the head to change brain activity, and ketamine, a drug that can reduce depression symptoms quickly. The authors say both treatments can help many people, but some still do not get better. Early research suggests that giving both treatments together might make the benefit stronger or last longer, but the evidence is not yet certain and more research is needed to work out how best to combine them.

Key facts:

• The paper is a review. That means the authors read and summarized recent studies about using transcranial magnetic stimulation and ketamine for depression.
• Transcranial magnetic stimulation, which uses magnetic pulses on the scalp, and ketamine, a fast-acting antidepressant drug, each can reduce the severity of depressive symptoms for many people.
• Some people with depression do not improve enough from either TMS or ketamine when those treatments are used alone.
• Recent studies suggest that combining TMS and ketamine may produce stronger or longer-lasting improvements than either treatment by itself.
• The review aims to explain possible brain mechanisms behind any extra benefit from the combined approach and to guide future research and treatment plans. It also notes that current evidence is preliminary and more studies are needed before the combined approach can be considered proven.

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.
