Transcranial magnetic stimulation (TMS) is a noninvasive procedure that uses magnetic fields to stimulate nerve cells in the brain to improve symptoms of major depression. Unlike surgical methods, TMS is performed without cutting the skin or invasive procedures. The U.S. Food and Drug Administration (FDA) has approved TMS for depression when other treatments have been ineffective. It is also approved for obsessive-compulsive disorder (OCD), migraines, and smoking cessation when standard treatments haven’t worked well. Research is ongoing to explore other potential uses for TMS, including epilepsy1.
TMS is known for significantly decreasing depression symptoms and improving mood. Another benefit to TMS is that unlike other brain stimulation methods, such as vagus nerve stimulation or electroconvulsive therapy (ECT), TMS doesn’t cause seizures, memory loss, or require anesthesia.
