[Ataxia, Involuntary Movement and Paroxysmal Motor Abnormality Associated with COVID-19 Infection].

The new coronavirus SARS-CoV-2 infection (COVID-19) has caused many casualties, mainly respiratory infections. However, it has also caused several neurological disorders including encephalitis/encephalopathy, demyelinating disease, Gullain-Barré sydrome etc. In addition, it has been clarified that movement disorders develop within a few days to weeks after infection. Vaccination for COVID-19 has progressed, but autoimmune neurological complications have also been reported. Although a causal relationship is suspected over time, this paper describes the pathophysiology of movement disorders such as myoclonus, opsoclonus, parkinsonism, and cerebellar ataxia, which are relatively common in COVID-19 infections, and their relevance to the SARS-CoV-2 vaccine.
