TMS is transcranial magnetic stimulation. A series of impulses are transferred into your brain by taps on your skull. It is not uncomfortable for me and the benefits obviously are worth any inconvenience of daily clinic visits. The effect seems like a reset for me (I get them yearly) enhancing my emotional wellness progress. I feel as tho even my meds are more effective. Mine is available by psych referral and testing. It is paid for by Medicare.
