What is Deep TMS?
Deep TMS, also known as dTMS, refers to a form of Transcranial Magnetic Stimulation that more deeply penetrates the brain. The procedure uses a special H1 coil that produces a magnetic pulse that can stimulate a larger area than the traditional figure 8 coils used in regular TMS. It’s commonly used to treat treatment-resistant depression.
The benefit of dTMS is that there is a more thorough stimulation to the targeted area of the brain, as well as the surrounding area that interconnects with the targeted spot. A treatment session consists of repeated pulses delivered over a span of approximately 20 minutes. Deep TMS yields higher rates of response and remission for treatment-resistant depression.
The risks of dTMS are minimal. The most common side effects are headaches and scalp discomfort. Both subside after a short period of time. In very rare instances, dTMS may cause seizures. The risk is extremely low though and is less likely than if a patient took common depression medications.
