Sleeping on hammock
Many seniors’ sleep habits are similar to those of young adults

More than half of all retired people aged 65 and over report sleeping at least 7.5 hours per night, and between the hours of 11 p.m. and 7:30 a.m., contrary to commonly held assumptions that most elderly go to bed early and have trouble sleeping through the night, according to a study by researchers at the University of Pittsburgh’s Sleep and Chronobiology Center (SCC) and University Center for Social and Urban Research (UCSUR).

Alzheimer’s plaques lead to loss of nitric oxide in brain

A researcher at the University of Pittsburgh School of Medicine, in collaboration with scientists from the National Institutes of Health (NIH), has discovered that the deadly plaques of Alzheimer’s disease interact with certain cellular proteins to inhibit normal signals that maintain blood flow to the brain. Their findings, which could lead to new approaches to treat the dementia, were recently published in Public Library of Science One.
