Transcranial magnetic stimulation

Transcranial magnetic stimulation (TMS) is a noninvasive neurostimulation technique in which a changing magnetic field is used to induce an electric current in a targeted area of the brain through electromagnetic induction. A device called a stimulator generates electric pulses that are delivered to a magnetic coil placed against the scalp. The resulting magnetic field penetrates the skull and induces a secondary electric current in the underlying brain tissue, modulating neural activity. Medical devices delivering repetitive transcranial magnetic stimulation (rTMS) have provided reasonably safe and effective treatments for major depressive disorder (MDD), chronic pain, and obsessive-compulsive disorder (OCD). They have shown evidence of effectiveness in the treatment of various neurological and psychiatric conditions—especially depression, neuropathic pain, and stroke recovery—and emerging advancements like intermittent theta burst...
