title: [Transcranial magnetic stimulation: review of accidental seizures].
abstract: Transcranial magnetic stimulation (TMS) is a new technique that has been used for the treatment of neuropsychiatric disorders, specially depression. It uses a magnetic stimulator that generates a magnetic field that is applied over the patient's skull with a coil. Possible seizures may be induced accidentally by TMS. TMS is usually used with sub threshold stimuli and seizures may occur by chance, especially when over the safety parameters. This article reviews the eight cases of undesirable seizures occurred with rTMS The possible mechanisms of seizure induction and the patients profile with a higher risk of convulsion are also described.
