Most side effects are mild and improve with time. They include…
- Headache or scalp discomfort
- Tingling, tension, or twitching of facial muscles
During TMS, you’ll sit in a chair with the magnet over your head. The magnet makes a click sound like a loud typewriter.
TMS has one serious risk. Very rarely, it can cause a seizure. These are extremely rare, though people with epilepsy may be at risk. Unlike electroconvulsive therapy (ECT), TMS does not work by inducing seizures.
