As stated, the most commonly reported side effect related to treatment is mild scalp discomfort. This side effect is temporary and lessens in frequency after the first week of treatment. Mild fatigue or headaches might also occur. Less than 5% of patients treated with NeuroStar TMS Therapy have discontinued treatment due to side effects. There is a small risk of a seizure during treatment which occurs in less than 1 in 30,000 treatments. However, this risk is actually less than what has been observed with most antidepressant medications.
