What to Expect With TMS Therapy: Before, During, and After
Starting transcranial magnetic stimulation (TMS) therapy can be a little anxiety-inducing if you’re not sure what the process actually looks like. TMS is an FDA-approved, noninvasive treatment for depression and certain other mental health concerns. It uses targeted magnetic pulses to stimulate specific areas of the brain involved in mood regulation, and is most commonly used when other treatments, such as therapy or medication, haven’t been effective. From your first consultation to each treatment session and the weeks that follow, understanding what to expect with TMS therapy before, during, and after can help you feel more comfortable, prepared, and confident as you begin the process.
Before
Before starting TMS, you’ll have a consultation where a provider will review your symptoms, treatment history, and overall health to determine whether TMS is actually a good fit for you. This is also when they decide which type of TMS approach is most appropriate, since different protocols can be used to target different conditions, most commonly depression, but also OCD and other disorders in certain cases. Your provider will map the area of your brain to be treated and explain what your schedule will look like. While many people follow a standard regimen of weekday daily sessions over several weeks, some clinics offer alternative approaches like accelerated TMS, which delivers multiple sessions in a much shorter time frame. The goal is to tailor the treatment plan to your needs while making the process as manageable and effective as possible.
During
During each TMS session, you’ll sit in a comfortable chair while a helmet-like device, or magnetic coil, is positioned against your scalp. As the treatment begins, the device delivers a series of magnetic pulses that often feel like a light tapping sensation on the head. It can feel unusual at first, but it’s not painful and is generally well-tolerated. You’ll remain awake and alert the entire time, and you can talk with the technician or relax during the session. Depending on the specific protocol, appointments can last anywhere from 20 to 40 minutes, though some newer or accelerated approaches may involve shorter or multiple sessions in a single day. Once the session is over, you can typically get right back to your normal activities.
After
After starting TMS, most patients follow a treatment course of about 5 sessions per week over 4 to 6 weeks, though this can vary depending on the specific protocol and condition being treated. Some people begin to notice subtle improvements like better sleep, increased energy, or a slight lift in mood within the first couple of weeks, while for others, changes build more gradually over the full course of treatment. By the end of the regimen, many patients report a significant reduction in symptoms, though results can differ from person to person. In some cases, providers may recommend additional “maintenance” sessions to help sustain the benefits over time, especially if symptoms begin to return.
