Researchers are trying to unravel why some COVID-19 survivors suffer “brain fog” and other problems that can last for months, and new findings suggest some worrisome overlaps with Alzheimer’s disease.
One study of older adults in Argentina found a surprising amount of dementia-like changes in memory and thinking for at least six months after a bout with the coronavirus — regardless of the severity of their infection. Other researchers found Alzheimer’s-related proteins in the blood of New Yorkers whose COVID-19 triggered brain symptoms early on.
The preliminary findings were reported at an Alzheimer’s Association meeting Thursday. Experts stress far more research is needed — and getting underway — to tell if COVID-19 might raise the risk of Alzheimer’s or other brain problems later in life, or if people eventually recover.
The possibilities “are real and troubling,” but it’s too soon to know “whether this is really going to result in
