Abstract

PURPOSE:

This study was designed to evaluate the therapeutic effect of low-frequency repetitive transcranial magnetic stimulation (rTMS) on patients with refractory partial epilepsy.

METHODS:

Sixty-four patients with refractory focal epilepsy were screened and 60 patients were randomly divided into two groups by stimulation intensity: 90% (group 1) or 20% (group 2) of resting motor threshold (rMT). Seizure frequency and interictal EEG epileptic discharges were compared between the baseline and follow-up periods.

KEY FINDINGS:

Seizures significantly decreased following 2-weeks high intensity (90% rMT) rTMS treatment compared with baseline level (p < 0.05). rTMS also decreased interictal epilepsy discharges and improved the scales of Symptom Checklist-90 significantly (p < 0.05). Seizures and spikes in the follow-up period in the patients who received low intensity (20% rMT) rTMS did not show any difference compared with baseline data (p > 0.05, respectively).

SIGNIFICANCE:

Low-frequency high intensity rTMS (90% rMT) delivered into the epileptogenic zone had a significant antiepileptic effect on patients with refractory partial seizures. rTMS treatment can also reduce the interictal epileptic discharge frequency and improve the psychological condition of these patients.
