A new index–developed by researchers at Columbia and USC–measures how countries are adapting to their aging populations.
Four areas of U.S. policy need immediate attention to improve health care for an aging population, say Columbia aging experts in a new report.
Despite widespread hearing loss among people in their 90s, only 59 percent of individuals in that age group use hearing aids, Columbia researchers found.
When injected into older animals, a hormone made by the skeleton of young animals dramatically improves exercise capacity, a new Columbia study finds.
Older adults who used a hearing aid performed significantly better on cognitive tests than those who did not use a hearing aid, despite having poorer hearing.
Neurologists find that moderate to intense exercise in people over age 65 may slow decline in memory and cognitive function by 10 years.
