'I thought my daughter had brain fog from long Covid but it was dementia'
Covid and Brain Damage
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.
Millions of people have long COVID brain fog — and there's a shortage of answers
"COVID. That, too, can basically be a cause of a brain injury."
The ‘Brain Fog’ of Long COVID Is a Serious Medical Issue That Needs More Attention
"new research has shown that long COVID can result in neurological damage and neurocognitive dysfunction that may cause lifelong impairment."
