To what extent is dementia preventable?

Regular readers know that my family has a history of Alzheimer’s Disease and/or dementia. This is true on both my mother’s and father’s side. So, at 77, I am totally focused on anything that relates to these mental conditions. The following is from the Keck School of Medicine at USC by Erica Rheinschild.

Experts say that one-third of the world’s dementia cases could be prevented by managing lifestyle factors such as hearing loss, hypertension and depression.

This remarkable fact was part of a report by the first Lancet Commission on Dementia Prevention and Care that was presented at the Alzheimer’s Association International Conference (AAIC) 2017 and published in The Lancet. The report also highlighted the beneficial effects of nonpharmacologic interventions such as social contact and exercise for people with dementia. Continue reading

Does walking satisfy cardiovascular exercise needs?

Regular readers know that I am a big fan of the simple exercise of walking. I have called it the Cinderella of the exercise world because it is so unappreciated. Check out my Page – Why you should walk more for further details on this superb form of movement.

No comes Megan Teychenne and Clint Miller writing in The Conversation about the nature and value of walking.

“Walking leads to a remarkable reduction in the risk of heart disease, type 2 diabetes, some cancers, arthritis, depression, anxiety and insomnia, and premature death from all causes.

Stanford professor Michel Serres hikes the Dish on a regular basis.

“The health benefits of walking stem from the changes that occur in our body systems as a result of exercising. For some of these health conditions, fitness has been shown to be a particularly important factor for prevention.

“The term fitness is quite often used to describe , but having a high level of fitness actually refers to all components of health-related physical fitness which includes muscular strength and endurance, flexibility, body composition, and of course aerobic (or heart) fitness. So is walking enough in terms of the we need?

6 Exercises You’ll Want To Do Every Day

As an old retired guy, 17 years, but who’s counting, ‘finding the time’ isn’t something I do any more. For those of you with regular jobs, I apologize for my forgetfulness. I realize that sometimes, when you have a demanding job/career, it can be difficult to impossible to ‘find the time’ to exercise. So, I thought I would share this excellent post from the Professionals Health Connection blog on working in some working out.

Professionals Health Connection

With your total workout taking less than 20 minutes a day (just 12.5 minutes if you follow the guidelines below exactly), you can’tsay no to these movements and even better, your body will love you for it!

Let’s face it, your body wants attention! It wantsto move! And with the amount of sitting in front of a computer most people do every day, ergonomic and even gaming chairs are being designed so you can sit for longer periods of time more comfortably. Unfortunately, that doesn’t mean sitting longer is good for you.

What does it take to be a super-ager? – Harvard

One of the stated aims of this blog is to live past 100. Posts every day touch on that goal, but mostly in a ‘part of the big picture’ way. Herewith some positive ideas from Harvard Health publications directly on the subject of super-aging.

Finding role models who are older than we are gets more difficult as we age. But in the last few years, medical science has identified a new group we can aspire to join — the super-agers. The term refers to people in their 70s and 80s who have the mental or physical capability of their decades-younger counterparts.

Although super-agers’ brains show less cell loss than those of their contemporaries, their IQs and educational levels are similar. What sets them apart might be that they view problem-solving differently, Dr. Dickerson says. “They may approach these tasks as a challenge they can succeed at, in contrast to typical older adults who may give up.” Continue reading

Check out interval walking – Harvard

I have written numerous times about the value of walking as an exercise. I have a Page – Why you should walk more which I hope you will check out for further details on this superb form of exercise. Well, now comes Harvard Health Publications with a fresh look at this old exercise – Interval Walking.

walking-posture

Warm weather is here, and you may be walking more to take advantage of being outside. Why not ramp up your routine with bursts of fast-paced walking? The technique, known as interval walking, “is a great way to get the most exercise bang for your buck,” says Dr. Aaron Baggish, associate director of the Cardiovascular Performance Program at Harvard-affiliated Massachusetts General Hospital.

About interval training

Interval walking is a form of interval training, which describes any form of exercise in which you purposely speed up or slow down at regular intervals throughout the session. The benefits of interval training in athletes and people in cardiac rehabilitation are well studied. Dr. Baggish says interval walking hasn’t been examined as much, but he believes the same benefits apply. “Something about strenuous exercise is good for the body. It improves endurance, reduces blood pressure, and helps with weight loss,” he explains. Continue reading

Weight and Alzheimer’s risk – Tufts

With both Alzheimer’s and dementia in my family, I am interested in all research on the subject.

100915_fobette-main

Tufts reported the following in its Health and Nutrition Letter.

Could a trimmer waistline in middle age help you avoid Alzheimer’s later in life? That’s the suggestion of a study, published in Molecular Psychiatry, from the National Institute on Aging. Researchers analyzed data on 1,394 participants in a long-running study of aging, followed for an average of 14 years, who regularly underwent cognitive testing. A total of 142 participants developed Alz­heimer’s disease during the study.

After adjusting for other factors, each additional point of body-mass index (BMI) at age 50 was associated with an earlier onset of Alzheimer’s of 6.7 months. “Our findings clearly indicate that higher adiposity at midlife is associated with a long-lasting effect on accelerating the clinical course of Alzheimer’s disease,” Madhav Thambisetty, MD, PhD, and colleagues concluded.

The study was not designed to prove cause and effect, however, and it’s not clear whether the association between obesity and Alzheimer’s risk might begin even earlier. It’s also true that newly diagnosed Alzheimer’s patients tend to weigh less than normal, not more.

The Joys and Benefits of Bike Riding – May is National Bicycle Month

There will be lots of celebrations of the bicycle in the coming four weeks because May is National Bicycle Month. As regular readers know, I ride around 7000 miles a year, an average of over 20 miles per day. So cycling is a labor of love for me.

I have tried to explain to myself first as well as others who asked, why I love to ride my bike. Until recently, the best I could come up with is that I feel like I am flying. Not soaring high, just flying along several feet above the bike path.

I know that when I ride, I am at once totally in the moment of propelling the bike forward and at the same time I experience a very enjoyable feeling of expansion – an almost out of body sensation.

This has been wonderfully explained by former University of Chicago professor, Mihaly Csikszentmihalyi in his book Flow. Continue reading

Is there an ‘exercise pill’ in our future?

Suppressing production of the protein myostatin enhances muscle mass and leads to significant improvements in markers of heart and kidney health, according to a study conducted in mice. Joshua T. Butcher, PhD, a postdoctoral fellow at the Vascular Biology Center at Augusta University, will present the work at the American Physiological Society’s annual meeting during the Experimental Biology 2017 meeting, held April 22–26 in Chicago.

The researchers zeroed in on myostatin because it is known as a powerful inhibitor of skeletal muscle growth, meaning that people with more myostatin have less muscle mass and people with less myostatin have more muscle mass. Studies suggest obese people produce more myostatin, which makes it harder to exercise and harder to build muscle mass.

“Given that exercise is one of the most effective interventions for obesity, this creates a cycle by which a person becomes trapped in obesity,” Butcher said. Continue reading

Exercise benefits Parkinson’s suffers – Study

I would like to thank reader, Garry, for tipping me off to this study on Parkinson’s disease and exercise.

From an analysis of more than 3,400 patients with Parkinson’s disease, researchers found that those who engaged in a minimum of 150 minutes of physical activity a week experienced much slower declines in health-related quality of life (HRQL) and mobility over 2 years, compared with patients who exercised less than 150 minutes weekly.

dscf6189

Note: This recommendation exactly equals that of the U.S. Dept of Health and Human Services. Which states: Adults 18 to 64 should get:
2.5 hours/wk of moderate intensity exercise.
OR 1.25 hours a week of vigorous aerobic physical activity
Or Some combination of the above – equivalent episodes of at least 10 minutes spread throughout the week. Continue reading

Is Physical Exercise Better Than Brain Exercise for Seniors?

The split between mind and body seems clearest in the realm of exercise. Each is good for us, but is one better?

Professor Sam Wang, Ph.D. Molecular Molecular Biology and Neuroscience, Princeton University covers the subject extensively in Lecture 23 of his course The Neuroscience of Everyday Life which I took from The Great Courses.

Opinion has been split on the subject.

“It is exercise alone that supports the spirits and keeps the mind in vigor.” – Marcus Tullius Cicero – 65 BC.

“Exercise invigorates and enlivens all the faculties of body and mind…. It spreads a gladness and a satisfaction over our minds and qualifies us for every sort of business, and every sort of pleasure.” – John Adams, Second President of the U.S.

On the other hand, that curmudgeon, Mark Twain said, “I take my only exercise acting as pallbearer at the funeral of my friends who exercise regularly.”

Brain

The business of brain-training is a multi-million dollar operation. It includes software and games we can play on our computers, Nintendo, smart phones as well as specialized machines. Also, there are the puzzles, like Sudoku, crosswords and other pattern recognition games.

How to sneak exercise into your day

Eat less; move more; live longer. Let’s be more specific about that moving part.

According to the U.S. Dept of Health and Human Services:

Adults 18 to 64 should get:
2.5 hours/wk of moderate intensity exercise.
OR 1.25 hours a week of vigorous aerobic physical activity
Or Some combination of the above – equivalent episodes of at least 10 minutes spread throughout the week.

That is really not a lot of exercise to sneak into a seven-day week. But, this is an old guy who has been retired for 17 years talking. What about the guy/gal who is clocking 50 or more hours a week on a demanding job with after work dinners and out of town travel assignments. All of a sudden a total of 2.5 hours a week becomes difficult to downright impossible.

Consider a desk that allows you to stand to protect yourself from the damage of prolonged sitting.

Well, WebMD has some really good ideas on how to squeeze some exercise into each day – even with a demanding job. You can check them all out at the link, but here are some that particularly impressed me. Continue reading

More exercise, less weight cut heart attack risk – Study

Lifestyle patterns, including regular exercise and staying slim, are associated with a risk of overall heart failure but are more strongly associated with the heart failure subtype HFpEF, according to a study published today in the Journal of the American College of Cardiology.

Before getting into the study, I want to reiterate the mantra of this blog: eat less; move more; live longer. Certainly words to live by.

Heart failure is a medical condition defined by the inability of the heart to meet the demands of the body, particularly during exertion. Heart failure with preserved ejection fraction (HFpEF) is a subtype of heart failure that involves the heart and other organs and is characterized a stiff heart muscle that is unable to fill adequately with blood, resulting in fluid backing up into the lungs and body.

78484731_t670x470

Heart failure with preserved ejection fraction accounts for up to 50 percent of heart failure cases and is associated with poor outcomes. It has also proven to be resistant to available therapies, leading to prevention being a critical part of controlling the growing burden of this disease.

“We consistently found an association between physical activity, BMI and overall heart failure risk,” said Jarett D. Berry, MD, associate professor in the department of internal medicine and clinical sciences and director of cardiac rehabilitation at the University of Texas Southwestern Medical Center in Dallas, and the study’s senior author. “This was not unexpected, however the impact of these lifestyle factors on heart failure subtypes was quite different.”(my emphasis)

Exercise can boost your memory and thinking skills

Eat less; move more; live longer. That is the mantra of this blog. moving more keeps the organic machines we know as our bodies in tip top shape. As it turns out exercise is also good for the old cabeza.

Moderate-intensity exercise can help improve your thinking and memory in just six months.

You probably already know that exercising is necessary to preserve muscle strength, keep your heart strong, maintain a healthy body weight, and stave off chronic diseases such as diabetes. But exercise can also help boost your thinking skills. “There’s a lot of science behind this,” says Dr. Scott McGinnis, an instructor in neurology at Harvard Medical School.

Exercise boosts your memory and thinking skills both directly and indirectly. It acts directly on the body by stimulating physiological changes such as reductions in insulin resistance and inflammation, along with encouraging production of growth factors — chemicals that affect the growth of new blood vessels in the brain, and even the abundance, survival, and overall health of new brain cells.

dscf6189

It also acts directly on the brain itself. Many studies have suggested that the parts of the brain that control thinking and memory are larger in volume in people who exercise than in people who don’t. “Even more exciting is the finding that engaging in a program of regular exercise of moderate intensity over six months or a year is associated with an increase in the volume of selected brain regions,” says Dr. McGinnis.
