rTMS

Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive treatment that uses a rapidly changing magnetic field to target neurons, creating a weak electric current. It is used to treat depression, strokes, and other neurological and psychiatric conditions. At the 2013 meeting of the American Psychiatic Association (APA), researcher Linda L. Carpenter reported on new findings about the long-term effects of rTMS.

In the new research, which was led by Mark Andrew Demitrack, 307 patients with unipolar depression who had not responded well to previous antidepressant treatment were given rTMS. They were treated in 43 different clinical practices and administered rTMS according to their evaluating physician, following FDA guidelines. Of the 307 patients who began the study, 264 benefited from initial treatments with rTMS, were tapered off rTMS, and agreed to participate in a one-year follow-up period, by the end of which 68% had improved and 40.4% had achieved complete remission as measured by the Clinical Global Impressions scale for severity of illness.

However, some study participants (30.2%) had worsened by the first follow-up assessment at the 3-month mark, and rTMS had to be re-introduced.
