Step-by-Step: What to Expect During Your First TMS Session
If you’re new to Transcranial Magnetic Stimulation (TMS) and wondering what to expect during a TMS session, you’re not alone. Many people feel a mix of curiosity and nervousness before starting this FDA-approved depression treatment. Let’s walk through it step-by-step so you know exactly how it works, how it feels, and what happens before, during, and after.
Understanding the Basics of TMS
TMS is a non-invasive therapy that uses magnetic pulses to stimulate nerve cells in the brain. It’s commonly recommended for individuals who haven’t found relief from traditional antidepressants. The key benefit is that it targets specific brain regions linked to mood regulation without the need for surgery or anesthesia.
Step 1 — Pre-Session Consultation
Before your first appointment, your provider will review your medical history, current symptoms, and any medications you’re taking. They’ll also explain TMS therapy side effects (which are usually mild, like scalp discomfort or headaches). This step ensures the treatment is safe and tailored to your needs.
Step 2 — Measuring and Mapping Your Brain
On your first day, the technician uses a process called “motor threshold mapping.” This determines the exact spot and intensity for the magnetic coil placement. It might sound high-tech, but it’s painless and only takes a few minutes.
Step 3 — The Treatment Session
You’ll be seated in a comfortable chair. A magnetic coil will be placed gently against your head. During the session, you might hear clicking sounds and feel light tapping on your scalp — this is completely normal. The stimulation usually lasts about 20–40 minutes depending on your personalized plan.
Step 4 — After the Session
One of the biggest advantages of TMS is that there’s no downtime. You can drive yourself home, return to work, or continue your day as usual. Some people report feeling a bit fatigued after the first few sessions, but this usually improves as the body adjusts.
How Many Sessions Are Needed?
A typical TMS course involves 5 sessions per week for about 4–6 weeks. Your provider will adjust the plan based on your progress and comfort level.
