Lifting the mask on neurological manifestations of COVID-19

Abstract

As the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) epidemic spreads, it is becoming increasingly evident that coronavirus disease 2019 (COVID-19) is not limited to the respiratory system, and that other organs can be affected. In particular, virus-related neurological manifestations are being reported more and more frequently in the scientific literature. In this article, we review the literature on the association between COVID-19 and neurological manifestations, present evidence from preclinical research suggesting that SARS-CoV-2 could be responsible for many of these manifestations, and summarize the biological pathways that could underlie each neurological symptom. Understanding the mechanisms that lead to neurological manifestations in patients with COVID-19 and how these manifestations correlate with clinical outcomes will be instrumental in guiding the optimal use of targeted therapeutic strategies.

  • Neurological manifestations affect between 4.2 and 100% of studied COVID-19 patients.

    “As reviewed by Pezzini and Padovani, neurological manifestations affect between 4.2 and 100% of studied patients: dizziness (prevalent in 7.6–46.1%), headache (5.1–77.1%), impaired consciousness (9.5–64.1%), and seizures (1.2–26%) [22].”
  • In COVID-19 patients presenting at least one neurological symptom, the prevalence of acute stroke (2.9-76.8%), confusion (14.2-65%), and encephalitis (0-27.9%) stands out.

    “Noteworthy, in COVID-19 patients presenting at least one neurological symptom, the prevalence of acute stroke (2.9–76.8%), confusion (14.2–65%), and encephalitis (0–27.9%) stands out.”
  • COVID-19 patients also present impaired taste (10-19.2%), smell (6-21.7%), dysautonomia (4.3-12%), and acute inflammatory demyelinating polyneuropathy (0-16,2%).

    “COVID-19 patients also present other nervous system symptoms, such as impaired taste (10–19.2%) and smell (6–21.7%), dysautonomia (4.3–12%), and acute inflammatory demyelinating polyneuropathy (0–16,2%) [22].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
