Objective To analyze the related factors of cognitive impairment in patients with post-traumatic epilepsy. Methods From January 2016 to January 2019, 45 patients with post-traumatic epilepsy (epilepsy group) and 48 patients with physical examination (control group) at the Department of Neurosurgery, the 904th Hospital of PLA were analyzed retrospectively. Cognitive assessment were evaluated by the following scales: Montreal cognitive assessment (MoCA), Mini-mental state examination (MMSE), Audio verbal memory test (AVMT), Rey-osterrieth complex figure test (CFT) and Trail making test (TMT). Then we analyzed the influences of gender, age, course of disease, cause, type, degree and location of injury, seizure frequency and Anti-seizure medications (ASMs) on cognitive impairment. Results The results showed that there were significant differences between the epilepsy group and the control group in all scales (P<0.01). Analysis of influencing factors in epilepsy group showed: MoCA and MMSE scores: there were statistical significance in the comparison of seizure frequency and injury degree (P<0.05); AVMT, CFT and TMT scores: there were statistical significance in the comparison of seizure frequency, injury degree and location, ASMs within the group (P<0.05). Conclusion Post-traumatic epilepsy can cause cognitive impairment. The more frequent epileptic seizures and the more severe the degree of trauma, the more serious the cognitive impairment. Different injury sites affect the scope of cognitive impairment, temporal lobe injury is easy to cause memory function decline, frontal lobe injury is easy to cause spatial structure and executive ability decline, at the same time, the combined use of ASMs has an impact on cognitive function.
