One of the most common questions people ask before starting TMS therapy is simple: does it hurt? In most cases, patients do not describe TMS as painful in the way they expected before treatment. The more common description is a tapping, knocking, or pulsing sensation on the scalp while the magnetic pulses are being delivered.
What does a TMS session feel like?
During a TMS session, you stay awake and alert. You sit in a chair, the coil is positioned against your scalp, and the treatment begins. You may hear clicking sounds from the machine, and you may feel repeated taps on the head in the treatment area. The sensation can feel unusual during the first few sessions, especially for people who are anxious before starting, but many patients find that it becomes easier to tolerate as they get used to it.
What are the common side effects?
Side effects of TMS are generally mild to moderate and improve shortly after a session. They may include:
- Mild scalp discomfort, especially at the beginning of treatment
- A mild, temporary headache after a session
- Brief facial muscle twitching during treatment, caused by stimulation of nearby nerves and muscles
- Lightheadedness that passes quickly
These effects usually lessen over the course of treatment, and the treatment team can adjust stimulation settings to reduce discomfort.
Is TMS safe?
TMS is generally considered very safe when done under proper medical supervision. It is non-invasive, drug-free, and does not require anesthesia. Unlike electroconvulsive therapy (ECT), TMS does not involve sedation and does not usually cause memory problems. That is one of the main reasons many people consider it a more approachable option when they are looking for a treatment beyond medication – see our comparison: TMS vs medication vs ECT.
What are the rare risks?
The most serious known risk with TMS is seizure, but this is rare. That is why screening is such an important part of the process. Before treatment starts, the psychiatrist and treatment team carefully review your medical history, medications, seizure history, and whether you have metal implants or medical devices (such as pacemakers, cochlear implants, or aneurysm clips) that may affect safety.
Will TMS change my personality?
Many people worry that because TMS acts on the brain, it might somehow change their personality or make them feel unlike themselves. In reality, the aim of treatment is not to change who you are. The goal is to improve the brain circuits involved in depression and emotional regulation so that you can feel more like yourself again.
Nervous about your first session?
For most patients, it is more accurate to say that TMS may feel uncomfortable or unfamiliar at first, rather than truly painful. The sensation is real, but it is usually manageable, temporary, and easier than many people expect.
