Transcranial magnetic stimulation (TMS) is a noninvasive form of brain stimulation in which a changing magnetic field is used to induce an electric current at a specific area of the brain through electromagnetic induction. An electric pulse generator, or stimulator, is connected to a magnetic coil connected to the scalp. The stimulator generates a changing electric current within the coil which creates a varying magnetic field, inducing a current within a region in the brain itself.[1]: 3 [2]
TMS has shown diagnostic and therapeutic potential in the central nervous system with a wide variety of disease states in neurology and mental health, but has no demonstrated clinical worth for treatment of any other condition.[3]
Adverse effects of TMS appear rare and include fainting and seizure.[4] Other potential issues include discomfort, pain, hypomania, cognitive change, hearing loss, long-lasting or permanent cognitive impairment, long-lasting anxiety and depression, panic attacks, chronic headaches and migraines, dizziness, nausea, fatigue, depersonalization and derealization, and environmental sensitivities inadvertent current induction in implanted devices such as pacemakers or defibrillators.[4][5]
