From EurekAlert! - Breaking News: A review of epidemiological data has found evidence that people who spend fewer years in school may experience a slight but statistically significant delay in the realization that they're having cognitive problems that could be Alzheimer's disease. Scientists at the Alzheimer's Disease Research Center (ADRC) at Washington University School of Medicine in St. Louis reviewed data on 1,449 Alzheimer's patients from their center and 21,880 patients from the National Alzheimer's Coordinating Center (NACC), a collaboration of approximately 30 Alzheimer's disease research centers nationwide. "We may have a group of people who are at risk for slightly delayed detection of Alzheimer's disease," says lead author Catherine Roe, Ph.D., a neurology research instructor at the ADRC. In an earlier study of patients with a form of Alzheimer's disease linked to a genetic mutation, Roe and other Washington University researchers found patients with more years of education were likely to be diagnosed with Alzheimer's disease earlier. This suggested to the researchers that those with lower education levels may be slower to notice the early signs of disease, only going to see a specialist after their symptoms become impossible to ignore. "People with higher education levels may be more likely to have a job or a hobby that highlights early cognitive impairment as well as better access to medical care," Roe says. The School of Medicine is one of the leading medical research, teaching and patient care institutions in the nation, currently ranked fourth in the nation by U.S. News & World Report.
