Are there any long term risks associated with TMS?
According to The International Society for Transcranial Stimulation, in an article Managing the Risks of Repetitive Transcranial Stimulation published in CNS Spectrums, The long-term risks of rTMS are not known. However, the limited data available at this time (2002) from repeated application of high intensity, time-varying magnetic fields to humans, as in magnetic resonance imaging, do not suggest that they are significant.
