NIH-supported trials of testosterone therapy in older men report mixed results
February 21, 2017
In older men with low testosterone, one year of testosterone treatment improved bone density and corrected anemia of both known and unknown causes, but also increased the volume of coronary artery plaque, according to results reported from the...
Putting exercise to the test in people at risk for Alzheimer’s
February 6, 2017
Can exercise slow or prevent cognitive decline in older people who are at increased risk for Alzheimer’s disease? A new clinical trial led by NIA-supported scientists in collaboration with the YMCA aims to find out whether exercise may be an...
Hypothermia: A Cold Weather Hazard
February 2, 2017
With shorter days and dropping temperatures, it is important to keep in mind that older adults are particularly vulnerable to the health risks that can come with cold weather. Hypothermia—a dangerous drop in core body temperature—can...
NIH initiative tests in-home technology to help older adults age in place
January 25, 2017
Many older adults want to live at home independently as they age. Sometimes all they need is a little help from their family and friends—and the right technology. A new initiative led by the National Institutes of Health (NIH) aims to help...
Epigenetic age estimated by changes in DNA methylation predicts mortality
January 19, 2017
A person’s life expectancy is known to vary with chronological age, risk factors such as smoking, and health conditions such as heart disease. Add to that list a person’s “epigenetic age”—an estimate of biological age...
Calorie restriction improves health, survival in rhesus monkeys
January 19, 2017
Studies show that most short-lived species, such as yeast cells, benefit from calorie-restricted diets. Could the same be true for species that live longer? Researchers in two parallel studies—one conducted by the National Institute on Aging...

January 13, 2017
Mark your calendars April 6-7 for the upcoming Cognitive Aging Summit 2017 in Bethesda, Maryland. Researchers from across the country will gather to discuss promising areas of research into age-related brain and cognitive changes, with a special...
Harnessing gamma brain waves to clear Alzheimer’s proteins
December 29, 2016
Animal study tests novel way to influence Alzheimer's-related brain changes Gamma brain waves—electrical charges that help link and process information from all parts of the brain—are known to slow down in the brains of people with...
NIH awards aim to understand molecular changes during physical activity
December 13, 2016
The National Institutes of Health Common Fund announced today the first awards for the Molecular Transducers of Physical Activity in Humans Program, which will allow researchers to develop a comprehensive map of the molecular changes that occur in...
Adaptive brain network change supports healthy cognitive aging in rats
December 9, 2016
Why does our ability to remember fail as we age? Is age-related memory loss normal, or a sign of something worse, like Alzheimer’s disease? A new study in rats suggests that part of the answer may rest on how effectively different parts of the...
