Abstract: ［Abstract］Objective　To investigate the cognitive function and influencing factors in patients with status epilepticus．Methods　We collected 20 cases of patients with status epilepticus，and compared them with the control group．We asscessed the cognitive function of them and analyzed the related influencing factors of cognitive function．Mini-mental state（MMSE），Digital span test（DST），Digital symbol test（DST），Trail making test（TMT），Verbal fluency test（VFT）were applied to evaluate the cognitive function of patients with status epilepticus．Results（1）Cognitive features：Neuropsychologic test scores of patients with status epilepticus were lower than normal control group by applying with MMSE，DST of WAIS-R，DST，TMT and VFT，and the differences were statistically significant（P＜0.01）. （2）Influencing factors of congnitive function：Level of education， age and the number of medication were the main factors affecting cognitive function of patients with status epilepticus by multivariate stepwise regression analysis，particular level of education was the most evident． Conclusions　Patients with status epilepticus have cognitive impairment. Level of education，age and the number of drugs have an impact on cognitive function，and education level is the major influencing factor of cognitive function.
