TMS is one of the most effective procedures available for depression. TMS has been in use since 1985 and has been approved by the Food and Drug Administration (FDA) since 2008. Magstim TMS is the only TMS system with the durability of its effects established over 12 months. In a clinical trial, 2 out of 3 patients who had either responded to treatment or completely remitted their depression symptoms reported 12 months later that they remained at the level they were at the end of the trial. Additionally, after the trial, only 1 in 3 patients needed to return for ‘maintenance’ TMS sessions.
