Objective  To investigate the changes of cognitive function of epileptic patients after antiepileptic drugs (AEDs) therapy. Methods  Twenty eight cases of epileptic patients with new diagnosis and untreatment from March 2015 to February 2016 were collected. According to the seizure type, degree of attack and drug efficacy, patients were divided into three groups and treated with one of three AEDs, including Lamotrigine (LTG), Oxcarbazepine (OXC), and Sodium valproate (VPA). Among them, 11 were LTG group, 12 were OXC group and 5 were VPA group.Then the patients were followed up for 1 year. The clinical memory scale was used to analyze cognitive function of epileptic patients before and after therapy. Results  Compared to 30 cases of healthy volunteers, the scores of memory quotient (P<0.01), directed memory (P<0.05), associative learning (P<0.05) and image free recall (P<0.01) of epileptic patients were obviously decreased before AEDs therapy.AEDs therapy reduced or controlled seizures in new diagnostic epileptic patients, and the total effective rate was 85.7%. In the clinical memory scale tests, the scores of memory quotient (P<0.01), directed memory (P<0.05), associative learning (P<0.05), portrait characteristics contact memory (P<0.05) were improved after therapy. The scores of image free recall and meaningless graphics recognition were also improved, but there was no statistical significance. Besides, there was a statistically significant improvement in the score of portrait characteristics contact memory after LTG treatment (P<0.05), and directed memory after VPA treatment (P<0.05). Conclusions  Epileptic patients accompanied with cognitive deficits before drug intervention. Through standard AEDs treatment, seizures could be better controlled. The cognitive function of epileptic patients was not declined after short-term(within 1 year) intervention of LTG, OCX or VPA. Moreover some parts of the cognitive domain could be improved.
