Repetitive Transcranial Magnetic Stimulation

What is Repetitive Transcranial Magnetic Stimulation Therapy

Repetitive Transcranial Magnetic Stimulation (rTMS) is a form of therapy used to address neurological conditions in the brain, most notably depression. rTMS uses electromagnetic induction to induce weak electric currents in the brain using a rapidly changing magnetic field; this can cause activity in specific or general parts of the brain with minimal discomfort, promoting normal brain function.

 

A total of 289 studies on rTMS were published between 1990 and 2008, testing rTMS as a treatment tool for various neurological and psychiatric disorders including migraines, strokes, Parkinson's disease, dystonia, tinnitus, depression and auditory hallucinations. A meta-analysis in 2008 found rTMS effective for depression, with a greater effect size than antidepressant medication. Interestingly, rTMS was more effective in the absence of antidepressant medication than it was when used in conjunction with antidepressant medication.1


Comparison of effect sizes for depression treatment: antidepressants (0.46) vs rTMS (0.55); rTMS has a higher effect size.
