| Creutzfeldt-Jakob disease (CJD) is a rare rapidly progressive neurodegenerative disease.
The diagnosis of CJD is based on magnetic resonance imaging (MRI) findings, electroencephalography
(EEG), or 14-3-3 protein detection. We report a case of a previously-healthy
72 year-old woman, with evidence of coronavirus disease 2019 (COVID-19), who complained
of behavioral changes and rapidly progressive dementia. While hospitalized, she did not have
orientation to time and place and repeated an irrelevant sentence in response to questions.
Also, anomia and impaired comprehension was observed. Myoclonic jerks, abnormal signal
intensity at bilateral parieto-occipital cortices in MRI, periodic sharp wave complexes in EEG,
and increased lactate dehydrogenase in cerebrospinal fluid (CSF) highly recommended CJD as
the diagnosis. This is the second case of CJD after COVID-19 during this pandemic, which can
be an alarm to clinicians about the silent impact of COVID-19 on the central nervous system. |
