Abstract:

Objective Regional homogeneity(ReHo) method of resting state functional MRI was applied to study abnormal brain activity of childhood generalized tonic seizures,and detect pathophysiological mechanisms of it. Methods Resting state fMRI scanning were performed to 8 patients with childhood generalized tonic seizures and 30 healthy children.The MRI data were compared and analyzed by using ReHo analysis method, the ReHo value were calculated between two groups and the correlation were studied between the ReHo value and seizure duration. Result   Compared with control group, the brain regions of increased ReHo value in experimental group are located in deep brain nuclei(cingulate gyrus,precuneus,thalamus,et al.),motor related brain region, inferior frontal gyrus, occipital lobe,temporal gyrus,cerebellum;the brain regions of decreased ReHo value in experimental group are bilateral middle frontal gyrus, right middle temporal gyrus, left superior temporal gyrus, bilateral posterior central gyrus, lingual gyrus.The positive correlation between ReHo and epilepsy duration was found in the following brain regions: left precuneus, left superior parietal lobe, right precentral lobule, right postcentral lobule.At the same time negative correlation was found in the right precuneus, right angular gyrus, paracentral lobule. Conclusion ReHo analytical method can effectively reflect abnormal neurological functional change of the epilepsy patients, and help to investigate and explain the pathophysiology of idiopathic generalized tonic seizures.
