History of TMS for depression
Does TMS sound too new? Unsure if you want to consider TMS? Rest assured, this procedure has literally been well studied for decades! Michael Faraday in 1881, was able to create a magnetic field by running electricity through a coil and this is the physics that TMS takes advantage of. The first TMS device was made in 1985 by Anthony Barker and his colleagues. Research in the use of TMS for depression really picked up in the 1990s. By the 1990’s, there had been 90 clinical trials and several meta-analyses suggesting a moderate effect size. In 2008, that was the first time the FDA approved this treatment for treatment resistant depression. Not too long after, another large study funded by the National Institute of Mental Health (NIMH) again confirmed the effectiveness of TMS for depression. Both studies, the original one funded by Neurostar and the one done by NIMH found approximately a 14% remission rate. Afterwards, deep TMS was researched and also eventually gained FDA approval. This technique was found to have a remission rate of more than double that of the figure of 8 coils used by companies such as Neurostar and Magventure. As TMS has continued to gain more recognition, more and more health insurance companies are now willing to cover this service.
