Single-pulse TMS related syncopal spell in a healthy subject.

We report the following TMS-related seizure or spell. The subject was a 22-year-old healthy woman who had no risk factors and was not taking any medications. She was screened using a self-report questionnaire for contraindications for TMS, including past or present neurologic, cardiac, and psychiatric conditions, family history of epilepsy, sleep deprivation, medicinal or recreational drug use, and recent use of alcohol or high doses of caffeine. Written informed consent was then obtained.
