Abstract:Objective To explore the therapeutic effect of oxcarbazepine combined with magnesium valproate on post-stroke epilepsy in the elderly and its impact on oxidative stress.Methods A total of 92 elderly patients with post-stroke epilepsy admitted to the First Affiliated Hospital of Heilongjiang University of Chinese Medicine from August 2021 to September 2022 were randomly divided into a study group and a control group, with 46 patients in each group. The control group was treated with oral sustained-release magnesium valproate, while the study group received oxcarbazepine in addition to the treatment in the control group. The treatment was maintained for 3 months. The frequency of seizures, duration of individual seizures, daily activity ability, cognitive level, oxidative stress response, drug toxicity, and recurrence outcomes were compared between the two groups before and after treatment and at a 6-month follow-up.Results The differences in seizure frequency, duration of individual seizures, daily activity ability scores, Chinese Revised Wechsler Intelligence Scale scores, serum superoxide dismutase, and serum lipid peroxide between the two groups before and after treatment were higher in the study group than in the control group (P < 0.05). There was no statistically significant difference in the incidence of adverse reactions between the two groups (P > 0.05). The recurrence rate in the study group at 6 months was lower than that in the control group (P < 0.05).Conclusion Oxcarbazepine combined with magnesium valproate in the treatment of post-stroke epilepsy in the elderly helps improve the anti-epileptic effect, enhance cognitive function, alleviate oxidative stress damage, and is safe.
