Covid-19 associated<unk>  was first discovered by Moriguchi T. et al. a Japanese critical care physician in late February 2020 during the pandemic of SARS-CoV-2. Duong L et. reported a case of a young female with COVID-19 who developed meningoencephalitis without respiratory failure in Downtown Los Angeles in early April, 2020. Bernard-Valnet R et al. reported two cases of meningoencephalitis in patients with concomitant SARS-CoV-2 infection. There is no established system for the classification of SARS-CoV-2 related<unk> . There are three mechanisms proposed for pathophysiology of<unk> . SARS-CoV-2 directly reaches brain through cribriform plate which is located in close proximity to olfactory bulb. This is supported by the facts that some patients of COVID-19 present with anosmia and hyposmia. Viral interaction with ACE2 expressed on neurons lead to damage to neurons and inflamation (encephalitis) and inflammation of brain membranes<unk> . SARS-CoV-2 can reach brain via anterograde or retrograde transport with the help of motor proteins kinesin and dynein via sensory nerve endings, especially afferent nerve endings of vagus nerve from lungs.
