Parallel electrophysiological abnormalities due to COVID‐19 infection and to Alzheimer's disease and related dementia
Parallel electrophysiological abnormalities due to COVID‐19 infection and to Alzheimer's disease and related dementia
“Resting-state EEG abnormalities include EEG slowing (reduced alpha rhythm; increased slow waves) and epileptiform activity. An expert panel conducted a systematic review to present compelling evidence that cognitive deficits due to COVID-19 and to Alzheimer's disease and related dementia (ADRD) are driven by overlapping pathologies and neurophysiological abnormalities. EEG abnormalities seen in COVID-19 patients resemble those observed in early stages of neurodegenerative diseases, particularly ADRD”

A groundbreaking study aims to determine if long COVID-19 could lead to another type of dementia

“‘…there is evidence of fragments or an inflammatory kind of a massive inflammatory response that occurs triggered by COVID. And those inflammatory markers we tend to notice in the brain.’

And that could cause something called COVID-19 Cognitive Impairment.

‘And we are going to compare people with COVID cognitive impairment. To be clear on this, I think that COVID can cause cognitive impairment and maybe even dementia…’”

Study uncovers the basis of COVID-19-related brain fog | University of Minnesota

EXTREME and incomplete oversimplification of the many complex neurological issues caused by SarsCov2, but important facet of the vaguely defined “brain fog” of Long Covid and post-acute Covid lingering symptoms.

“Neurological symptoms have been widely observed in COVID-19 patients, with many survivors exhibiting persistent neurological and cognitive impairment. New research from the University of Minnesota found that COVID-19 triggers inflammation in the brain, which is linked to many COVID-related symptoms such as fatigue and ‘brain fog.’”

Long COVID and Dementia: The Link Is Still Elusive | ALZFORUM
154,000 veterans who had COVID were 1.4 times likelier to have a neurologic condition--memory problems, stroke, neuropathy, mental health disorders, migraines, or seizures--in year following illness. This was true for all COVID cases, from mild to severe.
