Three studies released at the annual Alzheimer’s Association International Conference in Denver last month presented data suggesting that COVID-19 in Alzheimer’s patients caused further deterioration of their dementia, and could be provoking dementia symptoms in others.
A USA Today report from July 29 on the studies says that “scientists have found changes in brain biology after hospitalization with COVID-19, problems lingering months after infection, and a link between smell loss and mental sharpness in older adults.... Researchers are concerned about the possibility that lingering brain symptoms might lead to dementia years or decades later. With many people complaining about brain fog, attention problems and confusion after COVID-19, researchers are exploring whether infections could have long-term consequences for the brain. Early studies are not reassuring.”
