Abstract
Central nervous system (CNS) infection is one of the important risk factors for epilepsy. COVID-19 pandemic, which is caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has primarily been considered to involve respiratory system only, but it can also affect the CNS. A wide range of neurological manifestations have been reported in SARS-CoV-2 infected patients including seizures, status epilepticus, stroke, which are considered as important risk factors for the development of epilepsy. In post-mortem, brain tissue samples of COVID-19 patients have shown neuropathological changes and presence of SARS-CoV-2 RNA and viral proteins. In this review, mechanisms of SARS-CoV-2 neuroinvasion like neuronal retrograde trans-synaptic route and vascular route are described along with important neurological manifestations in COVID-19 patients such as seizures and cerebrovascular diseases, which have been found to be associated with the development of epilepsy. Hence, an increased risk of future burden of epilepsy in susceptible COVID-19 survivors has been proposed and preventive measures are suggested. The present review highlights about the possible association between neurological manifestations and future risk of epilepsy in COVID-19 patients.
