Every patient is different. Most large TMS research studies provided treatment five days a week for 4-6wks up to 36 sessions for a figure of 8 coil treatment. H-coil treatments have been studied for 5 days a week of treatment followed by 12 weeks of treatment 2 times a week for a total of 44 sessions. There is no demonstrated toxicity from treatment beyond this amount of sessions and, in some situations, it may be reasonable to continue treatments beyond this number. Some people may require a schedule of maintenance treatments to maintain their treatment results.
