Hamsters with long Covid exhibits a neurodegenerative signature in the brainstem

“Using the golden hamster as a model, we provide further evidence that SARS-CoV-2 is neuroinvasive and can persist in the central nervous system, as we found viral RNA and replicative virus in the brainstem after 80 days of infection.”

COVID survivors may develop dementia

“COVID-19 survivors show signs of significant cognitive deficits which could become dementia even a year after having the virus.. The team [in India] found that more than 80% of people tested reported at least one of four symptoms – depression, anxiety, stress and insomnia – ranging from mild to severe.. At least 6.1% of the patients were diagnosed with mild cognitive impairment and 4% developed dementia. More than 60% of the patients experienced a loss of taste and smell during the active phase of the infection. This could alter the function of brain areas linked to cognitive ability and emotional well-being.."

COVID-19 survivors show signs of significant cognitive deficits which could become dementia even a year after having the virus1. They also have an increased risk of depression, anxiety and disrupted sleep.
