Abstract:【Objective】To explore the relationship of Montreal Cognitive Assessment (MoCA) score with serum levels of protein kinase C (PKC), insulin-like growth factor-1 (IGF-1), and brain-derived neurotrophic factor (BNDF) in epilepsy patients. 【Methods】Based on the MoCA scores, 80 epilepsy patients treated in our hospitals were divided into the cognitive impairment group (group A with MoCA score <26) and the non-cognitive impairment group (Group B with MoCA score ≥26). The basic information, electroencephalogram results, and serum indicators [PKC, IGF-1, BNDF, Interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α)] of the two groups were compared. The relationship of cognitive impairment with serum PKC, IGF-1, and BNDF levels was analyzed using Receiver Operating Characteristic (ROC) curve analysis. Multivariate Logistic regression analysis was used to identify the risk factors for cognitive impairment in epilepsy patients. 【Results】Among the 80 patients, 52 (65.00%) cases had cognitive impairment and were categorized into the group A, while 28 (35.00%) cases did not have cognitive impairment and were categorized into the group B. The proportion of patients with generalized seizures and epileptiform waves on electroencephalogram in Group A was higher than that in Group B. The levels of PKC, IGF-1, and BNDF in Group A were lower than in Group B (P<0.05). There were no significant differences in age, gender, duration of illness, family history of epilepsy, history of febrile seizures, IL-6, and TNF-α levels between the two groups (P>0.05). ROC analysis confirmed that the levels of PKC, IGF-1, and BNDF could be used to predict cognitive impairment, with area under the curve (AUC) values of 0.927, 0.732, and 0.862, respectively (all P<0.05). Multivariate Logistic regression analysis showed that generalized seizures, epileptiform waves on electroencephalogram, PKC<3.015 pg/mL, IGF-1<126.57 μg/L, and BNDF<7.635 μg/L were risk factors for cognitive impairment (P<0.05). 【Conclusion】MoCA scores in epilepsy patients are positively correlated with serum levels of PKC, IGF-1, and BNDF. Lower scores of MoCA indicate more severe cognitive impairment and lower serum levels of PKC, IGF-1 and BNDF. Generalized seizures, epileptiform waves on electroencephalogram, PKC<3.015 pg/mL, IGF-1<126.57 μg/L, and BNDF<7.635 μg/L are all risk factors for cognitive impairment in epilepsy patients, which should be given clinical attention.
