Changes in paroxysmal brainwave patterns of epileptics by weak-field magnetic stimulation

Bioelectromagnetics. 2000 Feb;21(2):94-9. doi: 10.1002/(sici)1521-186x(200002)21:2<94::aid-bem3>;2-7.


In order to assess the effects of weak-field magnetic stimulation on brain electrical activity in epileptics, three patients suffering from mesial temporal lobe epilepsy (MTLE) were exposed to DC magnetic fields of 0.9 and 1.8 millitesla (mT). The EEG activity was recorded simultaneously from intracranial electrodes inserted through the foramen ovale (FO) and scalp electrodes. Significant enhancement of interictal epileptiform activity was observed in two patients, while in one patient, magnetic stimulation resulted in the cessation of interictal spike/wave trains.
