Epilepsy is defined as a disorder of brain neural function,characterized by the persistent possibility of seizures,which are usually sudden,brief,and recurrent.Cognition is a process of receiving information from the external world and analyzing and processing it,such as memory,language,visual-spatial,executive,calculation,comprehension,and judgement.With the increasing awareness of health,more and more scholars have begun to pay attention to the relationship between cognitive dysfunction and epilepsy.Data shows that over 80%of epilepsy patients have lower cognitive abilities than healthy people,and over 50%of patients have significant cognitive problems,which have a negative impact on their quality of life even greater than the seizures themselves.Cognitive impairment in epilepsy patients not only hinders their own treatment progress,but also has a negative impact on their daily life,academic and job perfor-mance,which brings huge care and economic pressure to their families and a heavy economic burden to the whole society.This review aimed to assess cognitive modules and provide key information for early diagnosis and treatment of patients.
