Key results: Biological markers of brain injury, neuroinflammation and Alzheimer’s correlate strongly with the presence of neurological symptoms in COVID-19 patients. Individuals experiencing cognitive decline post-COVID-19 infection were more likely to have low blood oxygen following brief physical exertion as well as poor overall physical condition.
“These new data point to disturbing trends showing COVID-19 infections leading to lasting cognitive impairment and even Alzheimer’s symptoms,” said Heather M. Snyder, Ph.D., Alzheimer’s Association vice president of medical and scientific relations. “With more than 190 million cases and nearly 4 million deaths worldwide, COVID-19 has devastated the entire world. It is imperative that we continue to study what this virus is doing to our bodies and brains. The Alzheimer’s Association and its partners are leading, but more research is needed.”
