6 Ways to a better memory – Infographic

When I was in the working world, my memory was constantly being tested. Now that I am retired my memory concerns have morphed. Being a senior citizen, I feel more aware of and am more concerned about my memory for non-professional, but very personal, reasons. I have suffered from senior moments ever since I was in my fifties. I hope that is all they are and not a prelude to any serious cognitive situations. I thought this little infographic on building up your memory might be useful to you no matter what your age is.

Eating Fish every week linked to better sleep, higher IQ – Study

Children who eat fish at least once a week sleep better and have IQ scores that are 4 points higher, on average, than those who consume fish less frequently or not at all, according to new findings from the University of Pennsylvania published in Scientific Reports, a Nature journal.

Previous studies showed a relationship between omega-3s, the fatty acids in many types of fish, and improved intelligence, as well as omega-3s and better sleep. But they’ve never all been connected before. This work, conducted by the School of Nursing’s​​​​​​​ Jianghong LiuJennifer Pinto-Martin and Alexandra Hanlon and Penn Integrates Knowledge Professor Adrian Raine, reveals sleep as a possible mediating pathway, the potential missing link between fish and intelligence.

A salad a day may keep memory problems away – Study

If an apple a day keeps the doctor away, perhaps we finally have a follow up for seniors worried about slippage in cognition.

Eating about one serving per day of green, leafy vegetables may be linked to a slower rate of brain aging, according to a study published in the December 20, 2017, online issue of Neurology®, the medical journal of the American Academy of Neurology.

The study found that people who ate at least one serving of green, leafy vegetables a day had a slower rate of decline on tests of memory and thinking skills than people who never or rarely ate these vegetables. The difference between the two groups was the equivalent of being 11 years younger in age, according to study author Martha Clare Morris, ScD, of Rush University Medical Center in Chicago. (my emphasis)

“Adding a daily serving of green, leafy vegetables to your diet may be a simple way to foster your brain health,” said Morris. “Projections show sharp increases in the percentage of people with dementia as the oldest age groups continue to grow in number, so effective strategies to prevent dementia are critical.” Continue reading

Exercise helps brain functions – Study

As regular readers know, I think we should all exercise regularly to keep our bodies and brains functioning at their best levels. It’s nice to see that the phrase use it or lose it has value on more than one level.

Mount Sinai researchers have found a positive relationship between the brain network associated with working memory—the ability to store and process information relevant to the task at hand—and healthy traits such as higher physical endurance and better cognitive function.

These traits were associated with greater cohesiveness of the working memory brain network while traits indicating sub-optimal cardiovascular and metabolic , and sub-optimal health habits including binge drinking and regular smoking, were associated with less cohesive working memory networks.

This is the first study to establish the link between working memory and physical health and .

The results of the study were published online in Molecular Psychiatry on Tuesday, December 5, 2017.

The research team took brain scans of 823 participants in the Human Connectome Project (HCP), a large brain imaging study funded by the National Institutes of Health, while they performed a task involving working memory, and extracted measures of brain activity and connectivity to create a brain map of working memory. The team then used a statistical method called sparse canonical correlation to discover the relationships between the working memory brain map and 116 measures of cognitive ability, physical and mental health, personality, and lifestyle choices. They found that cohesiveness in the working memory brain map was positively associated with higher physical endurance and better cognitive function. Physical traits such as high body mass index, and suboptimal lifestyle choices including binge alcohol drinking and regular smoking, had the opposite association.

“Working memory accounts for individual differences in personal, educational, and professional attainment,” said Sophia Frangou, MD, PhD, Professor of Psychiatry at the Icahn School of Medicine at Mount Sinai. “Working is also one of the brain functions that is severely affected by physical and mental illnesses. Our study identified factors that can either support or undermine the brain network. Our findings can empower people to make informed choices about how best to promote and preserve health.”
