Diet, exercise and brain training counter cognitive decline

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.

Mis-remembering vs. forgetting – Seniors Study

As a 78-year-old concerned about his cognitive facilities remaining intact, this Penn State study caught my attention.

buddha-buddhism-statue-religion-46177.jpeg

Older adults often complain about forgetting, but Penn State psychologists suggest that another problem may be mis-remembering.

In a study, the researchers found that as people age, they may be more likely to rely on a type of memory — called schematic memory — that helps them remember the gist of an event, but not necessarily the details. This inability to remember details, though, could lead to difficulty in distinguishing between a memory of something that really happened and something that a person thought happened, but did not — a false memory.

You don’t have to lose cognitive function while aging – Study

With Alzheimer’s Disease and dementia on both sides of my family, I can’t tell you how good it makes me feel to run across studies like this that say the wheels don’t have to come off your mental functions as you age.

Gradual and variable change in mental functions that occurs naturally as people age, not as part of a neurological disease such as Alzheimer’s disease, is one of the most challenging health issues encountered by older adults, says a report from the Institute of Medicine. The aging process affects the brain just like any other part of the body. Known as “cognitive aging,” the type and rate of change can vary widely among individuals. Some will experience very few, if any, effects, while others may experience changes in their memory, speed of processing information, problem solving, learning, and decision-making abilities. The committee that carried out the study and wrote the report proposed three top actions individuals can take to help maintain optimal cognitive function with age.

“Changes in mental functions and capabilities are a part of aging and occur with everyone,” said committee chair Dan G. Blazer, the J.P. Gibbons Professor of Psychiatry Emeritus at Duke University Medical Center in Durham, N.C. “The extent and nature of these changes vary widely and are gradual, and aging can have both positive and negative effects on cognition. Wisdom and knowledge can increase with age, while memory and attention can decline.”

Aging can affect cognitive abilities needed to perform daily tasks, such as driving, following recipes, adhering to medication schedules, and paying bills, the committee said. As they get older, individuals of all ages should take the following three steps to help promote cognitive health:

Be physically active.
Reduce and manage cardiovascular disease risk factors, including high blood pressure, diabetes, and smoking.
Regularly discuss and review health conditions and medications that might influence cognitive health with a health care professional. A number of medications can have a negative effect — temporary or long term –on cognitive function when used alone or in combination with other medication.

Other actions that may promote cognitive health: Continue reading

A Lifetime of Regular Exercise Slows Down Aging

Regular readers know that I ride my bike pretty much daily here in Chicago and my 78th birthday occurred in January. I wrote about my physical condition then, but I have to tell you that finding this study was like a wonderful belated birthday present.

According to researchers, older adults who exercised for most of their lives showed signs of slowed down aging. The study reports those who actively cycled into older age had lower cholesterol levels and better immune systems than those who did not partake in regular exercise.

Field Museum

Here I am with my trusty riding companion, Gabi, who just turned 12 in December.

Researchers at the University of Birmingham and King’s College London have found that staying active keeps the body young and healthy.

The researchers set out to assess the health of older adults who had exercised most of their adult lives to see if this could slow down aging. Continue reading

2018 Physical Activity Guidelines Advisory Committee Submits Scientific Report

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.

cycling-bicycle-riding-sport-38296.jpeg

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.

Can you make up for years of poor eating? – Harvard

Our bodies are, in fact, organic machines. We dwell inside them and operate them in society. Sometimes, we forget that our machines need proper fueling and maintenance. When that happens, our bodies, like regular machines, begin to break down. Because they are organic in some cases we can simply correct our bad maintenance habits and revive them with exercise and good nutrition. But decades of neglect are another story.

pexels-photo-139681.jpeg

In your 20s, maybe you sometimes chose fast-food burgers and fries over healthier foods. Perhaps in the decades that followed you pursued a series of fad diets, questionable lifestyle choices, and too many days when you skipped your workout in favor of the couch.

You’re now repenting for the sins of the past, but the question is, can you undo the damage? Can you unclog clogged arteries (otherwise known as atherosclerosis) and reduce your risk of heart disease in the process? Continue reading

Seniors Need to Exercise – NIH

Exercise and physical activity are good for just about everyone, including older adults. Eat less; move more; live longer is the mantra of this blog as regular readers know.

No matter your health and physical abilities, you gain a lot by staying active. In fact, in most cases you have more to lose by not being active, according to The National Institutes of Health (NIH).

Seniors-exercising

This is one of those simple, but not easy ideas. The damning statistics of 60 percent overweight of which 30 percent are obese in the general population hold true for seniors aged 65 and over, too, according to the Centers for Disease Control and Prevention (CDC).

There is a fascinating refinement in those numbers. In the years 65 to 74, the percent of obesity jumps to 41.5 for men and 40.3 percent for women. For the next segment, aged 75 years and older, however, it then drops to 26.5 for men and 28.7 for women. So, that 65 to 74 period is a very dangerous one for our senior population.

My only conclusion is that many of the obese 65-74 year old folks simply died off as a result of their weight leaving only the healthier trimmer ones alive after 75 years old.

To combat the ravages of a sedentary life and obesity, the NIH recommends exercise.

“Here are just a few of the benefits.

Exercise and physical activity:
• Can help maintain and improve your physical strength and fitness.
• Can help improve your ability to do the everyday things you want to do.
• Can help improve your balance.
• Can help manage and improve diseases like diabetes, heart disease, and osteoporosis.
• Can help reduce feelings of depression and may improve mood and overall well-being.
• May improve your ability to shift quickly between tasks, plan an activity, and ignore irrelevant information.

“The key word in all these benefits is YOU—how fit and active you are now and how much effort you put into being active. To gain the most benefits, enjoy all four types of exercise, stay safe while you exercise, and be sure to eat a healthy diet, too!

“Exercise and physical activity fall into four basic categories—endurance, strength, balance, and flexibility. Each type is different, though. Doing them all will give you more benefits.”

Obesity is a killer. I have written about it in several posts, check out What are Some Obesity Statistics? How Does Obesity Affect You?” Public Largely Ignorant About Obesity Risks. There are more posts on the danger of obesity, but those will give you a start. If you want to read further, type obesity into the SEARCH box at the right.

How did we evolve to live longer?

Eat less; move more; live longer is the mantra of this blog. Now, it seems that our bodies are taking it upon themselves to extend our life span.

Research shows a collection of small adaptations in stress activated proteins, accumulated over millennia of human history, could help to explain our increased natural defenses and longer lifespan.

14%20-%201-114.gif

Publishing in Nature Communications, the team of collaborators from the UK, France and Finland and lead by researchers at Newcastle University, UK explain the importance of a protein called p62.

Many cells in our body, such as those which make up our brain need to last us a lifetime. To do this our cells have developed ways of protecting themselves. One way is through a process called autophagy, which literally means self-eating, where damaged components are collected together and removed from the cell.

This is very important as accumulation of damage in cells has been linked to several diseases including dementia.

Lead author, Dr Viktor Korolchuk from Newcastle University’s Institute for Ageing explains: “As we age, we accumulate damage in our cells and so it is thought that activating autophagy could help us treat older people suffering from dementia. In order to be able to do this we need to understand how we can induce this cell cleaning.”

Some insights into weight and aging – Web MD

I love these WebMD quizzes. I thought this was a particularly germane one for us.

There are only nine questions, but I want to offer a couple of sample. You can take the quiz here.

exercising
I only missed a couple (wheew!). Since I have been writing this blog for nearly 10 years, I expected to crush it.

Here are a couple of examples:

True or False – Thinner is better as you get older. Unlike the majority of our lives, things change as we age. The answer is, “You want to be healthy, not frail. For older adults, what matters most is how active you are and whether you can do all your everyday activities. While it’s important to stay at a healthy weight, how much of your weight ”

I thought that was an excellent insight which many people would not know.

True or False. Gaining weight is a fact of aging. This one is also not obvious. “You can keep your weight steady as you age. It does get harder, but it’s possible. Those corners you cut when you were younger (huge portions, happy hours, little to no exercise)? You can’t   But age doesn’t have to equal weight gain.”

I must admit that the statement, You can’t get away with them anymore, is, I think, no secret to any of us over 50.

Fitness over 50: Overcoming a sedentary lifestyle – Harvard

I remember 20 years ago when I was in the working world, I definitely lived a sedentary lifestyle. Long hours at the office, a child at home and all the aspects of family life made it difficult for me to exercise a lot. Vedging out in the evening in front of the TV proved a welcome relief from daily demands. In addition, my motivation was elsewhere. Now that I am retired that has all changed, but I understand if you may be where I was back then.

btd2-12

Here I am riding with Gabi. Cycling is a super form of exercise for both mind and body.

Blame it on a job change, a chronic health issue, or simply a loss of motivation: whatever took you away from your regular exercise routine has led to a sedentary lifestyle. But don’t assume you can jump back into the same exercise regimen you followed when you were younger. “Your body has aged, and things have changed,” says Dr. Clare Safran-Norton, clinical supervisor of rehabilitation services at Harvard-affiliated Brigham and Women’s Hospital.

What’s different

Age-related physical changes aren’t always obvious. “We lose muscle mass and strength as we get older, and the muscles become less flexible and less hydrated,” says Dr. Safran-Norton. Arthritis weakens joints. And vision changes, neurological disease, joint pain, or problems inside the ear can throw off your balance. Continue reading

Aerobic exercise may ease some Alzheimer’s symptoms

Regular readers how focused I am on the connection between exercise and the brain. I lost three family members to Alzheimer’s Disease or another form of dementia. And, I just turned 78 two weeks ago. So, I was most interested in this report on the benefits of aerobic exercise on Alzheimer’s symptoms. When you finish reading, please check out my Page – Important facts about  your brain (and exercise benefits.)

Alzheimer’s Disease is a brain disorder that destroys memory and thinking skills over time. It is the most common form of dementia in older adults. There is presently no cure for the condition, though treatment options are available. Today, some 5.3 million Americans live with Alzheimer’s Disease, and it is the sixth leading cause of death in the United States. The number of older adults who will develop AD is expected to more than triple by 2050.

Geriatrics experts have suggested that exercising can improve brain health in older adults. The World Health Organization (WHO) has recommendations for how much older adults should exercise. They suggest that older adults perform 150 minutes a week of moderate exercise (such as brisk walking), 75 minutes a week of vigorous aerobic training, or a combination of the two types. The WHO also recommends older adults perform muscle-strengthening exercises on at least two or more days a week. Continue reading

HOW TO LIVE A LONGER AND HEALTHIER LIFE

There are some excellent insights here on the eating aspects of living a long and healthy life.

venitism

Biochemist Valter Longo has devoted decades to discovering connections between nutrition and successful aging. He runs the Longevity Institute at the USC Leonard Davis School of Gerontology, where the focus is on extending healthy life spans and finding ways to prevent and treat conditions like cancer and cardiovascular disease that growing older makes us more susceptible to developing. Longo is also a professor of biological science at the USC Dornsife College of Letters, Arts and Sciences.

Armed with results from the lab — including clinical trials showing that cycles of a five-day fasting-mimicking diet can reduce risk factors for many life-threatening diseases — Longo is calling for change in the kitchen. In this Q&A, he reveals the role that food can play in keeping us youthful and tackles some common misconceptions related to how, what and when we should eat.

Turmeric compound could boost memory and mood

I have eaten and enjoyed Indian food back in the late 1970’s when I lived in London and didn’t eat meat. Those days are long gone, but I do keep hearing good things about turmeric. Here is a nice rundown from Medical News Today on it.

Not a lover of Indian food? A new study might change your mind. Researchers have found that a compound in turmeric — the spice that gives curry its golden color — could help to improve the mood and memory of older adults.

your-expert-guide-to-turmeric-header-v2-830x467.jpg

Turmeric has been linked to a wealth of health benefits. Last year, for example, Medical News Today reported on a study suggesting that turmeric could help to treat pancreatic cancer, while other research claims the popular spice may help to treat stroke and Alzheimer’s disease. Continue reading

Everyday habits can bolster your memory muscles – Harvard

Regular readers know that I have had several members of my family, or both sides, suffer from dementia in general or Alzheimer’s in particular. So, being a guy in his late 70’s I am particularly sensitive to any kind of cognitive kinks that I may be experiencing. I don’t know if it is my imagination or there are simply more people coming on board the cognitive improvement movement. Herewith, Harvard Healthbeat on tips for strengthening your memory.

Your daily habits and lifestyle — what you eat and drink, whether you exercise, how stressed you are, and more — affect your mental health every bit as much as your physical health. A growing body of research indicates that regular exercise and a healthful diet can help protect your memory from aging-related decline. (my emphasis)

ahr0cdovl3d3dy5saxzlc2npzw5jzs5jb20vaw1hz2vzl2kvmdawlza4ns81ntcvb3jpz2luywwvynjhaw4tbmv1cm9ucy5qcgc.jpeg

Exercise

Physical fitness and mental fitness go together. People who exercise regularly tend to stay mentally sharp into their 70s, 80s, and beyond. Although the precise “dose” of exercise isn’t known, research suggests that the exercise should be moderate to vigorous and regular. Examples of moderate exercise include brisk walking, stationary bicycling, water aerobics, and competitive table tennis. Vigorous activities include jogging, high-impact aerobic dancing, square dancing, and tennis.

Exercise helps memory in several ways. It reduces the risk of developing several potentially memory-robbing conditions like high blood pressure, diabetes, and stroke. Exercise is good for the lungs, and people who have good lung function send more oxygen to their brains. There is some evidence that exercise helps build new connections between brain cells and improves communication between them. Finally, exercise has been linked to increased production of neurotrophins, substances that nourish brain cells and help protect them against damage from stroke and other injuries.

 

Here are some ways to build physical activity into your daily routine:

Walk instead of driving when possible.

Set aside time each day for exercise. For extra motivation, ask your spouse or a friend to join you.

Use the stairs instead of the elevator.

Cognitive Training Helps Regain a Younger-Working Brain

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.

830c88f78a26b084002c883eb628074e

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

Why older men should do more housework – Study

As an older guy, I turn 78 in less than two weeks, I am interested in my health and certainly my longevity. So, the subject of older men doing more housework caught my attention. Also, housework does not rank high on my list of fun stuff to do.

The following is what Medical News Today reported:

According to a new study, it seems that elderly adults are stuck in a time when housework was the woman’s job. Researchers have found that every day, older women spend an average of 2 hours more doing household chores than men.

pexels-photo-278312.jpeg

But it’s not all bad. Older men and women who engage in more housework might have better health. Though if women get too much or too little sleep, the health benefits of housework diminish.

The new study — which was recently published in the journal BMC Public Health — was led by Nicholas Adjei and Tilman Brand, of the University of Bremen in Germany.

The research was designed to get a better idea of how adults spend their time in later life, and how certain day-to-day activities impact their health.

“The percentage of those aged 65 years and above,” explains study co-leader Adjei, “is increasing globally due to higher life expectancy. It is important to understand how older adults spend their time in these later years and the possible positive and negative implications for their health.” Continue reading
