It appears that the frequency of neurological symptoms is associated with COVID-19 disease severity. In the aforementioned study of 214 hospitalized patients with COVID-19 infection (41% severe and 59% non-severe disease), severe patients were more likely than non-severe patients to have neurologically related manifestations (45.5% vs. 30.2%, respectively). In this study, the most frequently reported neurological manifestations for severe and non-severe patients, respectively, were acute cerebrovascular disease (5.7% vs. 0.8%), impaired consciousness (14.8% vs. 2.4%) and skeletal muscle injury (19.3% vs. 4.8%) [52]. This does not take into account more diffuse symptoms, such as confusion or headache, which may also be neurological [51].
