[Abstract] Objective: To study the changes of the level of brain function in patients with temporal lobe epilepsy (TLE), and to explore the relationship between them and the executive function using degree centrality (DC).Materials and Methods: The executive function of 21 patients with disease duration≤5 years, 19 cases of disease> 5 years of TLE patients and 30 healthy controls were studied by using attention network test (ANT). At the same time, the DC values of resting-state functional magnetic resonance imaging (rs-fMRI) were calculated, and the correlation between the DC values of the extracted brain regions and the efficiency of the control reaction was analyzed.Results: The efficiency of the control group was significantly lower than that of the control group (P<0.05). Compared with the control group, the brain area of the patients with less than 5-year-old group was located in the right hippocampus, and the brain area in the 5-year-old group was located in the right caudate nucleus, the left frontal lobe and the DC increased brain area was located on the left side of the central anterior, central posterior; course of disease> 5 years of patients than the course of ≤5 years of patients with DC increased brain area in the left island leaves. (cluster threshold at P<0.01, Alphasim corrected). The DC value of the right caudate nucleus in the 5-year group was negatively correlated with the efficiency of the control network (P<0.05).Conclusions: TLE patients with impaired function, different course of patients with brain area connection intensity (node) are different, different course of patients with executive function and different brain connection, only found in patients with longer course of the brain part of the existence of compensatory effect, and the functional connection intensity of the caudate nucleus is related to the execution function.
