Both rTMS and dTMS treatments are administered over a time period of between 4-6 weeks. Twenty minute dTMS sessions are generally shorter than the circa 37 minute sessions for rTMS.nnFollowing treatment, many patients feel better for many months afterward, with the average duration noted to be about a year. Among the 50-60% of patients who do find relief, about one-third experience full remission, meaning that they do not experience any symptoms.
