Low-frequency repetitive transcranial magnetic simulation prevents chronic epileptic seizure

摘要

Although low-frequency repetitive transcranial magnetic simulation can potentially treat epilepsy,its underlying mechanism remains unclear.This study investigated the influence of low-frequency repetitive transcranial magnetic simulation on changes in several nonlinear dynamic electroencephalographic parameters in rats with chronic epilepsy and explored the mechanism underlying repetitive transcranial magnetic simulation-induced antiepileptic effects.An epilepsy model was established using lithium-pilocarpine intraperitoneal injection into adult Sprague-Dawley rats,which were then treated with repetitive transcranial magnetic simulation for 7 consecutive days.Nonlinear electroencephalographic parameters were obtained from the rats at 7,14,and 28 days post-stimulation.Results showed significantly lower mean correlation-dimension and Kolmogorov-entropy values for stimulated rats than for non-stimulated rats.At 28 days,the complexity and point-wise correlation dimensional values were lower in stimulated rats.Low-frequency repetitive transcranial magnetic simulation has suppressive effects on electrical activity in epileptic rats,thus explaining its effectiveness in treating epilepsy.
