Abstract:
Objective At present, there is no study on effect of levetiracetam(LEV) on the gray matter structure remodeling in benign epilepsy children with central temporal spikes(BECTS).The purpose of this study was to study the influence of LEV on the gray matter structure in BECTS and to evaluate the mechanism of LEV on the brain structure of BECTS through using voxel-based MRI morphological(VBM) methods.Methods From January 2014 to September 2016, twenty-four BECTS treated with LEV(LEV group), twenty-four drug-na?ve BECTS(untreated group) and twenty-four normal children(normal group) consulted in department of Neurology, Nanjing Children′s Hospital and the Nanjing Military Region, Nanjing General Hospital were continuously included to receive three-dimensional T1-weighted imaging with 3T MRI and the gray matter volume was calculated by VBM.We compared the difference of grey matter volumes of the three groups and analyzed their correlation with epilepsy duration, age of onset and medication time and other clinical index.Results Compared with the normal group, the grey matter volume of bilateral thalamus were decreased, and the volume of bilateral Rolandic areas, anterior insula/frontal operculum/frontal triangle, left supplementary motor area, paracentral lobule, precentral gyrus, superior frontal gyrus and right middle frontal gyrus were increased in the untreated group, but the grey matter volume of the bilateral Rolandic areas, frontal operculum and left supplementary motor area were decreased in the LEV group.Compared with the untreated group, the grey matter volume of bilateral supplementary motor, left paracentral lobule, precentral gyrus, bilateral anterior insula/frontal operculum/frontal triangle, left superior frontal gyrus and right middle frontal gyrus in the LEV group were decreased.The grey matter volume of left anterior insula/frontal operculum areas was negatively correlated with the medication time in LEV group(r=-0.527, P<0.01).Conclusion T The mainly representations of BECTS are thalamic gray matter damage and epileptic-related cortical area irritation structural abnormalities, but the LEV could reshape the epilepsy-related cortical area and the gray matter in the brain area associated with clinical symptoms.
