This is wonderful news. I love everything about it. My blog is based on exactly these principles. Eat intelligently and get your exercise and your brain will benefit in your declining years. Well done!
A comprehensive program providing older people at risk of dementia with healthy eating guidance, exercise, brain training, and management of metabolic and vascular risk factors appears to slow down cognitive decline, according to the first ever randomized controlled trial of its kind, published in The Lancet.
In the Finnish Geriatric Intervention Study to Prevent Cognitive Impairment and Disability (FINGER) study, researchers led by Professor Miia Kivipelto from the Karolinska Institutet in Stockholm, Sweden, National Institute for Health and Welfare in Helsinki, and University of Eastern Finland, assessed the effects on brain function of a comprehensive intervention aimed at addressing some of the most important risk factors for age-related dementia, such as high body-mass index and heart health.

Eat less; move more; live longer has been the mantra of this blog for years. I am always gratified to see those sentiments echoed elsewhere. The latest version comes from the government of all places and it dwells particularly on the aspect of exercise.
The 2018 Physical Activity Guidelines Advisory Committee, a group of nationally recognized experts in physical activity and public health, has submitted its recommendations to the U.S. Department of Health and Human Services (HHS) Secretary and disbanded.
The 2018 Scientific Report reinforces the recommendations included in the 2008 Physical Activity Guidelines that physical activity reduces the risk of a large number of diseases and conditions. In addition to disease prevention benefits, the Scientific Report includes findings that regular physical activity provides a variety of benefits that help people sleep better, feel better, and perform daily tasks more easily. The Committee also found that some benefits happen immediately, on the same day a single bout of physical activity is performed.
Expanding on findings from the Advisory Committee Scientific Report, 2008, the 2018 Committee identified health benefits of physical activity that had not been previously identified including:
Improved bone health and weight status for children ages 3 to 5
Improved cognitive function for children ages 6 to 13
Decreased risk of certain cancers, dementia, and excessive weight gain for adults
Improved quality of life and sleep for adults
Reduced feelings of anxiety and depression in adults
Additional benefits for specific population including older adults, women who are pregnant or postpartum, and individuals with pre-existing medical conditions
Additionally, the Committee found strong or moderate evidence that more time spent in sedentary behavior is related to greater all-cause mortality, cardiovascular disease mortality and incidence, type 2 diabetes incidence, and the incidence of certain cancers.
Get Involved: The Department has published the 2018 Physical Activity Guidelines Advisory Committee Scientific Report online and the public is encouraged to view the Scientific Reportand provide written comments to the federal government at https://health.gov/paguidelines/pcd. The comment period will be open until 11:59 pm E.T. April 2, 2018.
Relentless cognitive decline as we age is worrisome, and it is widely thought to be an unavoidable negative aspect of normal aging. Researchers at the Center for Brain Health at The University of Texas at Dallas, however, say their research could provide new hope for extending our brain function as we age.
In a randomized clinical study involving adults age 56 to 71 that recently published in Neurobiology of Aging, researchers found that after cognitive training, participants’ brains were more energy efficient, meaning their brain did not have to work as hard to perform a task.
Dr. Michael Motes, senior research scientist at the Center for BrainHealth and one of the lead authors of the study, said, “Finding a nonpharmacological intervention that can help the aging brain to perform like a younger brain is a welcome finding that potentially advances understanding of ways to enhance brain health and longevity. It is thrilling for me as a cognitive neuroscientist, who has previously studied age-related cognitive decline, to find that cognitive training has the potential to strengthen the aging brain to function more like a younger brain.” Continue reading
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.
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 Liu, Jennifer 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.

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
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 health, 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 lifestyle choices.
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 memory 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 working memory brain network. Our findings can empower people to make informed choices about how best to promote and preserve brain health.”
