At the American Diabetes Association's annual meeting in June 2001, Eve Van Cauter, Ph.D., reported that people who regularly do not get enough sleep can become less sensitive to insulin. This increases their risk for diabetes and high blood pressure – both serious threats to the brain.
Previous work by Dr. Van Cauter, a professor of medicine at the University of Chicago, found that "metabolic and endocrine changes resulting from a significant sleep debt mimic many of the hallmarks of aging. We suspect that chronic sleep loss may not only hasten the onset but could also increase the severity of age-related ailments such as diabetes, hypertension, obesity, and memory loss ."
