Creutzfeldt-Jakob Disease in a Patient with Previous COVID-19 Infection: “The Virus Caused the Derangement in My Brain”

Abstract

Recent studies have speculated a link between Creutzfeldt-Jakob disease (CJD) and COVID-19, following the description of CJD cases after COVID-19 infection. We report the case of a 71-year-old female patient who developed neuropsychiatric and neurological symptoms after COVID-19 infection and was later diagnosed with CJD. Cerebrospinal fluid (CSF) total tau levels were slightly increased. She resulted prion protein gene (PRNP) M129V heterozygous. We aim to emphasize the role of the polymorphism at codon 129 of PRNP gene on the clinical phenotype and duration of CJD, and the CSF total tau levels that likely correlate with the rate of disease progression.
