The ability for TMS to provide relief of symptoms varies greatly from person. Therefore the length of a TMS Therapy course can vary greatly. Your doctor will recommend a schedule of sessions based on your individual need and response to treatment. So while patients typically receive 20-30 treatments over a 4-6 week period, the actual number of treatments can range anywhere from 10-60 treatments over a 4-10 week period. Treatments are performed during the weekdays usually five days a week and each procedure lasts approximately 30-60 minutes.
