Transcranial magnetic stimulation is shown in the image.
Transcranial magnetic stimulation
- It is a magnetic method used to stimulate small regions of the brain. During a TMS procedure, a magnetic field generator, or “coil”, is placed near the head of the person receiving the treatment.
- The coil produces small electric currents in the region of the brain just under the coil via electromagnetic induction. The coil is connected to a pulse generator, or stimulator, that delivers electric current to the coil.
- TMS is used diagnostically to measure the connection between the brain and a muscle to evaluate damage from stroke, multiple sclerosis, amyotrophic lateral sclerosis, movement disorders, motor neuron disease, and injuries and other disorders affecting the facial and other cranial nerves and the spinal cord.
- For neuropathic pain, for which there is little effective treatment, high-frequency (HF) repetitive TMS (rTMS) appears effective.
- For treatment-resistant major depressive disorder, HF-rTMS of the left dorsolateral prefrontal cortex (DLPFC) appears effective
- Areas of research include:
- Rehabilitation of aphasia and motor disability after the stroke.
- Anxiety disorders, including panic disorder and obsessive-compulsive disorder.
- The most promising areas to target for OCD appear to be the orbitofrontal cortex and the supplementary motor area.
- Amyotrophic lateral sclerosis
- Multiple sclerosis
- Alzheimer’s disease
- Parkinson’s disease
- Substance abuse, addiction, and posttraumatic stress disorder (PTSD).
- Brain death, coma, and other persistent vegetative states.
