Through non-invasive treatments, TMS stimulates nerve cells in the area of the brain that regulates mood
The Science of TMS
During TMS therapy, an electromagnetic coil is placed on the head over the left prefrontal cortex, an area of the brain thought to be involved in mood regulation.
The coil then produces a pulsed magnetic field. This passes non-invasively into the head and stimulates the nerve cells in the area of the brain beneath the coil.
TMS therapy is based on knowledge of physical principles dating back nearly 175 years. In 1831, Michael Faraday discovered that a magnetic field could be converted into an electrical current. That basic discovery has been applied to create the powerful and focused electromagnetic coil that stimulates the brain in TMS therapy.
First used in 1985, TMS has been used by researchers around the world to help understand the function of different parts of the brain, and several hundred manuscripts have been published regarding its use in stimulating select regions of the brain.
The History of TMS as Treatment for Depression
In the late 1990’s, physicians began to explore the potential of TMS therapy for the treatment of a variety of diseases, with depression being the most thoroughly studied to date.
More than 75 randomized, controlled trials of TMS therapy as a treatment for depression have been published by investigators around the world. In 2006, the largest randomized, controlled study ever conducted with TMS therapy was completed in patients with major depression, demonstrating its safety and efficacy for this use.
The Mag Vita TMS therapy system is the most recent advanced design in current TMS technology to be cleared by the U.S. F.D.A. (2013) for the treatment of adult patients with major depressive disorder who have failed to receive satisfactory improvement from prior medication antidepressant treatment.
