Covid-19 is associated with different neurological manifestations. About one third of Covid-19 patients have some neurological disorders as paresthesia, headache, cold extremities and disturbances of consciousness, which are more evident in severely affected patients. These neurological manifestations may coexist or precede the onset of respiratory manifestations by about 2-3 weeks. Acute ischaemic stroke (AIS) and associated brain damage may develop due to acute respiratory distress syndrome (ARDS) induced-hypoxia. Prolonged hypoxia in late-stage Covid-19 leads to vasodilatation, intracranial hypertension, brain oedema, and AIS. In view of substantial evidence, this perspective explores the potentially direct or indirect effect of SARS-CoV-2 on the Central Nervous System of patients with COVID-19 pneumonia. The AIS is the end of most Covid-19-induced neurological complications. Covid-19 can lead to various neurological manifestations due to involvement of CNS directly through olfactory neurons or indirectly through induction of cytokine storm.
