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.
