title: Repetitive Transcranial Magnetic Stimulation (rTMS)-Induced Trigeminal Autonomic Cephalalgia.
abstract: Repetitive transcranial magnetic stimulation (rTMS) is an effective and novel treatment method that has been approved for the treatment of refractory depression by the U.S. Food and Drug Administration. The most common side effects of rTMS are a transient headache that usually responds to simple analgesics, local discomfort in the stimulation area, dizziness, ipsilateral lacrimation and, very rarely, generalized seizure. TMS is also regarded as a beneficial tool for investigating mechanisms underlying headache. Although rTMS has considerable benefits in terms of headache, there is the potential for rare side effects. In this report, we present the case of a patient with no history of autonomic headache who underwent a course of rTMS for refractory unipolar depression caused by an inadequate response to pharmacotherapy. After his fourth rTMS session, the patient developed sudden headaches with characteristics of trigeminal autonomic cephalalgia on the stimulated side, representing a noteworthy example of the potential side effects of rTMS.
