Super-Agers and Memory Health

Super-Agers and Memory Health

Super-agers are a select group of adults in their 70s, 80s, and older who can match the memory performance of a typical 25 year old, and in some cases these older adults have far superior memory skills compared to people decades younger.

Most people begin to experience a subtle decline in memory in their 50s, with much of this “normal” decline related to cortical thinning and other age dependent changes in the brain.

So what is it about super-agers that help them perform cognitively like someone much younger?

A Super-Ager Brain Looks Like a Young Brain.

Researchers at Massachusetts General Hospital scanned the brains of a group of older adults with extraordinary memory performance and found that certain key areas of their brains important for memory were as healthy and robust as a 20-something brain – there were no signs of atrophy or thinning in the brains of super-agers.

Increasing the Odds on Becoming a Super-Ager

The chances of becoming a super-ager depends on a combination of genetic factors (the DNA lottery we all receive at conception), and a number of modifiable lifestyle factors.

These lifestyle choices include physical exercise, eating a healthy diet, not smoking, getting quality sleep, and having positive social connections.

Staying physically active can help minimize brain changes (such as cortical thinning) that come with aging. Physical activity supports good cardiovascular health, and also stimulates the neurotrophic factor BDNF, which helps the brain grow new neural connections.

Eating foods listed in the MIND diet, a hybrid of the Mediterranean diet (all around good for you) and DASH diet (follow to reduce high blood pressure). The MIND diet highlights the food and nutrients that research indicates is associated a lower risk of Alzheimer’s and dementia. Download the MIND diet list: mybraintest.org/healthy-bra...

Good sleep is necessary for new memory consolidation, aka learning! New memories formed during waking hours are very fragile. If you are studying for an exam, or learning new skills for a job, a good night’s sleep is essential for those memories to be consolidated and stored for later retrieval. Memory consolidation occurs through the sleep cycle, especially during REM sleep. Read the 5 Key Habits for Better Sleep: mybraintest.org/2016/05/fiv...
