Deep transcranial magnetic stimulation (dTMS)
What is dTMS?
Deep transcranial magnetic stimulation is a type of TMS that uses a specially designed coil to achieve deeper and broader penetration of electromagnetic stimulation into the brain. In people with obsessive-compulsive disorder, stimulation of the medial prefrontal cortex has been found to improve symptoms.
What is symptom provocation?
Research has found that the benefits of dTMS are greater if the targeted areas of the brain are active at the time of treatment. Symptom provocation is designed to activate areas involved in OCD symptoms prior to treatment. The purpose of this is to bring on your symptoms of OCD, but only to a limited degree of severity, immediately before the treatment session.
You have been referred for dTMS therapy for the treatment of your Obsessive compulsive disorder (OCD), because even though you have been receiving treatment, you are still experiencing symptoms.
Sessions typically take 30-45 minute sessions, which means they can easily fit in with your day.
Both TMS and dTMS stimulate targeted areas of the brain, but as the name suggests, dTMS reaches areas that are found deeper in the brain.
Side effects are usually mild, transient (pass quickly) and/or can be easily managed. The most common side effect is headache.
