Transcranial magnetic stimulation (TMS) is a procedure that uses magnetic fields to stimulate nerve cells in the brain to improve symptoms of major depression. It's called a "noninvasive" procedure because it's done without using surgery or cutting the skin. Approved by the U.S. Food and Drug Administration (FDA), TMS usually is used only when other depression treatments haven't been effective.

How it works

During an rTMS session for depression, an electromagnetic coil is placed against the scalp of your head. This coil delivers magnetic pulses that stimulate nerve cells in the region of your brain involved in mood control and depression. It's thought to activate regions of the brain that have decreased activity during depression.

You also may hear the term "deep transcranial magnetic stimulation" or "deep TMS." The difference between rTMS and deep TMS has to do with the type of coil used. The deep TMS coil stimulates deeper and wider areas of the brain, compared with rTMS. Deep TMS coils have been FDA-approved for OCD and to stop smoking.

Although the biology of why TMS works isn't completely understood, the stimulation appears to affect how the brain is working. It seems to ease depression symptoms and improve mood.

There are different ways to perform TMS. Methods may change as experts learn more about the most effective ways to perform treatments.
