Is TMS safe? What problems do patients commonly report?
TMS was introduced in the mid 1980s. It is generally agreed to be free from side effects when proper procedures are followed. Over the years since introduction, safety guidelines have been developed which minimize risks. The main complaint from a small percentage of patients is headache during and immediately following the stimulation session. This can be alleviated with over-the-counter pain medications such as aspirin or ibuprofen. It is believed that these headaches are caused by the inadvertent stimulation of nearby muscle groups, which results in tension headaches. Another common problem is ringing in the ears caused by the noise of the stimulating coil, so earplugs are typically worn during the procedure. Seizures are the major possible risk associated with TMS, although they have only been encountered in several patients thus far. While TMS safety guidelines established in 1993 and revised in 1996 go a long way to reducing the chances of seizure, the possibility still exists. It
