Transcranial Magnetic Stimulation
Transcranial magnetic stimulation (TMS) Treatments
Transcranial magnetic stimulation (TMS) is a noninvasive method that leads to depolarization or hyperpolarization of the neurons in the brain.
It uses electromagnetic induction through a rapidly changing magnetic field to induce weak electric currents. These then causes activity in specific or general parts of the brain with little discomfort, allowing doctors to study the brain's functions and interconnections.
How the process works
Transcranial Magnetic Stimulation is used for therapeutic purposes by applying magnetic fields to stimulate the motor zone of the cerebral cortex and peripheral nervous system in the brain. This improves the symptoms of several conditions such as depression, Alzheimer and migraine.
TMS uses a magnet instead of an electrical current to activate the brain. An electromagnetic coil is held against the forehead and short electromagnetic pulses are administered through the coil. The magnetic pulse passes easily through the skull and causes small electrical currents that stimulate nerve cells in the targeted brain region.
Because this type of pulse generally does not reach further than two inches into the brain, scientists can select specific parts of the brain to treat.
The short duration magnetic pulses can penetrate through clothes, cranium bones and soft tissues without any pain.
Transcranial Magnetic Stimulation can be applied in:
Neurology: neuropathy, myelopathy, Parkinson’s disease, multiple sclerosis, encephalopathy, pain
Psychiatry: Alzheimer disease, depression, schizophrenia
Orthopedics: reducing recovery time in fractures
Neurological and psychiatric disorders: migraine, stroke, Parkinson's disease, dystonia, tinnitus and depression
