Neuromuskuläre Komplikationen einer SARS-CoV-2-Infektion – Teil 1: periphere Nerven

Lehmann, Helmar C.; Schoser, Benedikt; Wunderlich, Gilbert; Berlit, Peter; Fink, Gereon R.

In recent months various disorders and diseases of the peripheral nerves (including cranial nerves) and the musculature have been described in association with the pulmonary disease coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). In the first part of our review the current knowledge about a potential association of a SARS-CoV‑2 infection with dysfunction and diseases of cranial and peripheral nerves is discussed. Anosmia, ageusia, motor cranial nerve involvement and Guillain-Barré syndrome (GBS) were described in a temporal association with a SARS-CoV‑2 infection. Several studies could show that anosmia and ageusia were frequent symptoms of a SARS-CoV‑2 infection. In contrast the failure of other cranial nerves has so far only been sporadically described. A number of case reports and case series indicate a causal association between a SARS-CoV‑2 infection and GBS but epidemiological evidence is still lacking.
