Washington: A 65-year-old woman, who has routine hip surgery, develops memory loss six months later and is diagnosed with Alzheimer`s. Just a coincidence? Researchers at the University of South Florida (USF) and Vanderbilt University don`t think so. They suspect that the culprit precipitating Alzheimer`s disease in the elderly women may be a routine administration of high concentrations of oxygen for several hours during, or following surgery - a hypothesis borne out in a recent animal model study.
