Transcranial magnetic stimulation (TMS) seems to be effective for the treatment of migraines with aura. “Spring TMS” device which delivers a jolt of such stimulation has been on the market in Europe since 2011. The American company that manufactures this device, eNeura Therapeutics hopes to obtain approval to sell it in the US in the near future. The approval of this device in Europe was based on a multi-center study results of which were published in Lancet Neurology. Unfortunately, the device is fairly bulky and needs to be carried around constantly because it seems to work only if used during the aura phase of the migraine. Auras usually begin unpredictably and last 20-60 minutes. Migraine with aura affects only 15-20% of all migraine sufferers, further limiting the potential market for this device.
