摘要：Background:Besides seizures,a myriad of overlapping neuropsychiatric and cognitive comorbidities occur in patients with epilepsy,which further debilitates their quality of life.This study provides an in-depth characterization of the impact of brivaracetam and rufinamide individually and in combination at 10 and 20 mg/kg doses,respec-tively,on corneal kindling-induced generalized seizures and behavioral alterations.Furthermore,observed convulsive frequency and behavioral changes were corre-lated to post-kindling-induced changes in the activity of markers of oxidative stress.
Methods:Adult C57BL/6 mice were kindled via twice-daily transcorneal 50-Hz elec-trical stimulations(3 mA)for 3 s for 12 days until animals reached a fully kindled state.After the kindling procedure,animals were tested using a set of behavioral tests,and neurochemical alterations were assessed.
Results:Corneal-kindled animals exhibited intense generalized convulsions,altered behavioral phenotypes typified by positive symptoms(hyperlocomotion),negative symptoms(anxiety and anhedonia),and deficits in semantic and working memory.BRV 10+RFM 20 dual regime increased convulsive threshold and propensity toward the start of stage 4-5 seizures and improved phenotypical deficits,that is,anxiety,depression,and memory impairments.Moreover,this combination therapy mitigated kindling-induced redox impairments as evidenced by reduced malondialdehyde and acetylcholinesterase levels and increased glutathione antioxidant activity in the brain of animals subjected to repetitive brain insult.
Conclusion:Based on our outcomes,this dual therapy provides supporting evidence in alleviating epilepsy-induced neurobehavioral comorbidities and changes in redox homeostasis.
