Abstract
ObjectiveThe objective of the study was to investigate the effects of slow repetitive transcranial magnetic stimulation (rTMS) on patients with refractory juvenile myoclonic epilepsy (JME). MethodsOne thousand pulses with the intensity of 120% active motor threshold (AMT) at 0.2 Hz frequency were applied on 5 consecutive days in 10 patients with refractory JME. Sham rTMS was performed after 3 months. Electroencephalography (EEG) examinations were performed before rTMS, on the 5th day, and 1, 2, 4, and 8 weeks after rTMS. Resting motor threshold (RMT), AMT, and cortical silent periods (CSPs) were recorded before the application and at the end of day 5. The changes in the quality of life were evaluated using the Quality of Life in Epilepsy Inventory (QOLIE-31). ResultsNo adverse effects were observed. The number of seizures decreased by 29–50%, and interictal discharge durations decreased 2 weeks after the real rTMS. No significant difference was observed between the AMT and RMT values recorded before and after the stimulations. Statistically significant increases in CSP duration and quality of life scores were found following real rTMS. Repetitive transcranial magnetic stimulation may be considered as a safe treatment option in refractory JME. ConclusionThis study provides some positive evidence that rTMS may be effective in resistant JME.
