In the largest observational study to date on 'SuperAgers' — people in their 80s who have brains as sharp as those 30 years younger — researchers in Spain found key differences in lifestyle that may contribute to these older adults' razor-sharp minds.
To be a SuperAger, a term the Northwestern SuperAging program coined, a person must be over 80 and undergo extensive cognitive testing. Acceptance in the study occurs if the person's memory is as good or better than cognitively normal people in their 50s and 60s — only 10% of people who apply qualify.
SuperAgers share similar traits, say experts who study them. They tend to be positive. They challenge their brain every day, reading or learning something new. Many continue to work into their 80s. Brain scans showed SuperAgers had greater gray matter volume than typical older adults in areas of the brain responsible for cognitive functioning, spatial memory and overall memory. In addition, some of the most impressive changes in gray matter volume were in areas of the brain connected to motor activity or movement as well as memory..) — including APOE4, a red flag risk for Alzheimer's disease — as normally aging adults. However, that finding is not new, experts say.
