Scientists have found that all subtypes of dementia behave like rapidly progressive dementia after being infected with COVID-19.
An international team of scientists investigated the impact of COVID-19 on cognitive impairment in 14 patients with pre-existing dementia (four with Alzheimer's disease, five with vascular dementia, three with Parkinson's disease dementia, and two with a behavioral variant of frontotemporal dementia) who suffered further cognitive decline after COVID-19.
The researchers suggested that COVID-19 should have some -some harmful effect on patients with pre-existing dementia, extrapolating understanding of the cognitive impact of this viral infection on patients without dementia. In addition to finding that all subtypes of dementia behaved like rapidly progressive dementia after COVID-19, scientists found that the demarcation line between different types of dementia became surprisingly blurred after illness.
