Transcranial magnetic stimulation
DefinitionBy Mayo Clinic staff
Transcranial magnetic stimulation is a procedure that uses magnetic fields to stimulate nerve cells in the brain to improve symptoms of depression. Transcranial magnetic stimulation may be tried when other depression treatments haven't worked.
With transcranial magnetic stimulation, a large electromagnetic coil is placed against your scalp near your forehead. The electromagnet used in transcranial magnetic stimulation creates painless electric currents that stimulate nerve cells in the region of your brain involved in mood control and depression. Because transcranial magnetic stimulation is a relatively new depression treatment, more studies are needed to determine how effective it is, which treatment techniques work best and whether it has any long-term side effects.
