ABSTRACT
Coronavirus disease 2019 (COVID-19) is a primary respiratory disease with an alarming impact worldwide. COVID-19 is caused by severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) and presents various neurological symptoms, including seizures. SARS-CoV-2 shows neuroinvasive and neurotropic capabilities through a neuronal angiotensin-converting enzyme 2 (ACE2), which is also highly expressed in both neuronal and glial cells. Therefore, SARS-CoV-2 can trigger neuroinflammation and neuronal hyperexcitability, increasing the risk of seizures'. Olfactory neurons could be an exceptional neuronal pathway for the neuroinvasion of respiratory viruses to access the central nervous system (CNS) from the nasal cavity, leading to neuronal injury and neuroinflammation. Although neuronal ACE2 has been widely studied, other receptors for SARS-CoV-2 in the brain have been proposed to mediate viral-neuronal interactions with subsequent neurological squeals. Thus, the objective of the present critical review was to find the association and mechanistic insight between COVID-19 and the risk of seizures.
