title: Seizure with single-pulse transcranial magnetic stimulation in a 35-year-old otherwise-healthy patient with bipolar disorder.
abstract: This case report describes a patient who developed a seizure with single-pulse transcranial magnetic stimulation during motor threshold estimation. The patient had no history of seizures in the past and no gross neurologic deficits. The only possible seizure-provoking factors were modest doses of lithium and chlorpromazine, which the patient was on, and family history of seizure in a brother. This report aims to highlight the fact that single-pulse transcranial magnetic stimulation may provoke a seizure even in the absence of gross neurologic abnormality.
