Tips on healthy aging – Infographic

44f12c3d100df24527e9bc6e73c487c4.jpg

If you would like more detail on items above, please check out the following posts:

Certainly one of the best concepts I have learned in producing this blog is that the brain benefits from exercise. It is the first item on the infographic above – Stay Active. I have written a Page on it – Important facts about your brain (and exercise benefits.)

Regarding the “Don’t be Salty” entry, it is important to keep in mind that most of the damaging salt we consume comes in the form of processed foods. Pay attention to the salt/sodium content in the foods you consume.

Stress damages us in many ways. I have written about it numerous times. You can search S T R E S S in the tags for more. One of the best posts on it is: Super tools for handling stress that I wrote in 2011. Check it out.

Last, but not least, ‘Be happy.’ I have covered the benefits of happiness in lots of posts. I think my Page – Positive psychology – What’s it all about? will also prove valuable information.

Exercise can boost your memory and thinking skills – Harvard

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

Happy days! More positive information on the benefits to the brain garnered from physical exercise! This time from Harvard Medical School.

brainexercise

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. Continue reading

Brain Detects Disease in Others Even Before it Breaks Out

Because my family history includes both Alzheimer’s Disease and dementia, I am fascinated by every aspect of the brain and its functions. The following is from Neuroscience News.

The human brain is much better than previously thought at discovering and avoiding disease, a new study led by researchers at Karolinska Institutet in Sweden reports. Our sense of vision and smell alone are enough to make us aware that someone has a disease even before it breaks out. And not only aware – we also act upon the information and avoid sick people. The study is published in the scientific journal Proceedings of the National Academy of Sciences (PNAS).

By injecting harmless sections of bacteria, the researchers activated the immune response in participants, who developed the classic symptoms of disease – tiredness, pain and fever – for a few hours, during which time smell samples were taken from them and they were photographed and filmed. The injected substance then disappeared from their bodies and with it the symptoms. NeuroscienceNews.com image is for illustrative purposes only.

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.

Our Better Health

You probably know that exercise and diet are important when it comes to aging well. But there is something else you control that can help you along: a positive attitude.

Research shows more and more that your approach to life may be just as important in making your “golden years” your best years.

Aging: It’s in Your Mind

Growing older brings with it some natural changes (think those creaky knees). But folks who see good years ahead and who don’t accept stereotypes about aging — such as you’re less useful — may actually live longer.

And there’s science to back that up.

One study found that thinking positively about getting older can extend lifespan by 7.5 years. And that’s after accounting for things such as gender, wealth, and overall health. Some 660 women and men in Ohio joined this study, and they were monitored for more than 20 years.

5 Lessons on making a happy life – Harvard

I am all for living a long and healthy life and this blog is filled with suggestions on achieving that. But, besides having a functional brain and body in our senior years, we also want to be happy about it. Harvard has studied a group of men and boys over the past 78 years in what is one of the longest studies of adult life ever done.

“The Harvard Study of Adult Development has tracked the lives of 724 men from the time they were teenagers into old age — 268 Harvard College sophomores, and 456 boys from Boston’s inner city.”

 

1dbf57a5bda004729413fea79f57be11

Here are five of the big lessons they learned about what contributes to a good life.

Lesson 1: Happy childhoods matter

Having warm relationships with parents in childhood predicts that you will have warmer and more secure relationships with those closest to you in adulthood. We found that warm childhoods reached across decades to predict more secure relationships with spouses at age 80. A close relationship with at least one sibling in childhood predicts that people are less likely to become depressed by age 50. And warmer childhood relationships predict better physical health in adulthood all the way into old age. Continue reading

Good every day habits to keep your memory in good shape – Harvard

As a senior citizen, I am aware of the aging process going on in both my body and my brain. I exercise to help preserve both. Here are some super suggestions from Harvard HEALTHbeat on bolstering the memory aspect of your brain.

2-brain

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. Continue reading

Active Gaming Good For Brain Health and Memory – Study

Video games which involve physical activity significantly boost our brain health as we get older, according to new research led by University of Manchester experts.

Study authors Dr Emma Stanmore and Joseph Firth say systems that use physical activity for gaming such as Wii, and Xbox Kinect can boost brain functioning in people with neurological impairment, as well as keeping our minds healthy and active as we age.

DARPA Funds Brain-Stimulation Research to Speed Learning

The Defense Advanced Research Projects Agency  (DARPA) is working with seven U.S. universities and elements of the Air Force and Army on research that seeks to stimulate the brain in a non-invasive way to speed up learning.

DARPA announced the Targeted Neuroplasticity Training, or TNT, program last March, and work now has begun on the effort to discover the safest and most effective ways to activate a natural process called “synaptic plasticity.”

170427-D-ZZ999-999.JPG

Plasticity is the brain’s ability to strengthen or weaken its neural connections to adapt to changes in the environment. For TNT Program Manager Dr. Doug Weber, such plasticity is about learning.

“We’re talking about neural plasticity, or how the neurons, which are the working units in the brain, how their function changes over time as we train on new skills,” he said during a recent interview with Department of Defense News.

Targeted Neuroplasticity Training

TNT research focuses on a specific kind of learning called cognitive skills training. People use cognitive skills to do things like pay attention, process information, do several things at once, detect and understand patterns, remember instructions, organize information and much more.

Exercise sharpens the mind in over-50s – Study

Eat less; move more; live longer is the mantra of this blog. Of course the most important element in living longer is having  a fully functioning brain. The BBC just filed a wonderful story supporting that outcome.

Doing moderate exercise several times a week is the best way to keep the mind sharp if you’re over 50, research suggests.

Thinking and memory skills were most improved when people exercised the heart and muscles on a regular basis, a review of 39 studies found.

This remained true in those who already showed signs of cognitive decline.

Taking up exercise at any age was worthwhile for the mind and body, the Australian researchers said.

Exercises such as T’ai Chi were recommended for people over the age of 50 who couldn’t manage other more challenging forms of exercise, the study in the British Journal of Sports Medicine said.

Genes Associated With Resilience Against Brain Pathology Identified

Having had three family members who suffered from some form of dementia I am highly motivated to find out all I can about this scourge that devastates mostly seniors. The following is from the Rush Alzheimer’s Disease Center.
Genes help cognition withstand damage in brain from Alzheimer’s, Parkinson’s

The pathologies (damage) in the brain that stroke, Alzheimer’s disease and other neurological conditions cause in older adults only partially explain the memory loss, reduced reasoning ability and other cognitive impairments that result from these conditions. Little is known about why the effects of brain pathology vary between people who develop it.

Senses

Now researchers have discovered two genes, known as UNC5C and ENC1, that are associated with aging individuals having better memory and brain function than would be expected, given the amount of pathologies that accumulated in their brains. They reported their findings in an article published today in the journal PLOS Medicine. Continue reading

Brain’s Power to Adapt Offers Short-Term Gains, Long-Term Strains

There is not necessarily fresh ground broken here, but I think seeing details on how the brain functions can only be helpful. The most important idea for me is one I had going in, namely, you only have one brain so take care of it.

Like air-traffic controllers scrambling to reconnect flights when a major hub goes down, the brain has a remarkable ability to rewire itself after suffering an injury. However, maintaining these new connections between brain regions can strain the brain’s resources, which can lead to serious problems later, including Alzheimer’s Disease, according to researchers.

brainexercise

After a head injury, the brain can show enhanced connectivity by using alternative routes between two previously connected regions of the brain that need to communicate, as well as make stronger connections, said Frank G. Hillary, associate professor of psychology, Penn State. These new connections between damaged areas are often referred to as hyperconnections, he added. Continue reading

Healthy living = a healthy brain as you age – Mayo Clinic

Eat less; move more; live longer is the mantra of this blog. Seems that a healthy lifestyle increases the chances of a healthy brain as we age, according to the Mayo Clinic.

Adopting a healthy lifestyle can protect the brain against several risk factors for Alzheimer’s disease, Mayo Clinic research shows. Controlling blood pressure and cholesterol and avoiding obesity, smoking and diabetes are among the steps that can help preserve brain health, according to the study, published in JAMA Neurology.

100915_fobette-main.jpg

Neurologists believe two aspects make up Alzheimer’s disease:

  • Amyloid deposits: Toxic proteins that build up plaques on the brain.
  • Neurodegeneration: Loss of structure and function of neurons in the brain.

The Mayo research examined whether the risk factors and protective steps against each differ. Continue reading

Mercury in Fish, Seafood May Be Linked to Higher Risk of ALS

We cut down on red meat to reduce the amount of bad fats in our system. Instead, we dive into eating fish to stay healthy longer. Well, it turns out that’s not a totally safe harbor, either.

Eating fish and seafood with higher levels of mercury may be linked to a higher risk of amyotrophic lateral sclerosis (ALS), according to a preliminary study released today that will be presented at the American Academy of Neurology’s 69th Annual Meeting in Boston, April 22 to 28, 2017. However, fish and seafood consumption as a regular part of the diet was not associated with ALS.

2012-11-29-16.30.15.jpg

“For most people, eating fish is part of a healthy diet,” said study author Elijah Stommel, MD, PhD, of Dartmouth College in Hanover, N.H., and a Fellow of the American Academy of Neurology. “But questions remain about the possible impact of mercury in fish.” ‘ 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.

Another Favorite – Visual Mind Games

At the risk or appearing like I am selling out on my idea of protecting my brain by exercising regularly, I would like to suggest this fun pastime as an additional line of defense against cognitive impairment.

I wrote this for another blog I write occasionally and thought it would be of interest to you. I know a lot of folks are doing adult coloring books these days for relaxation. I thought these puzzles would be a nice step up that could be more challenging to the imagination.

Willing Wheeling

I ran across these at an art fair years ago. They are wonderful brightly colored shapes that you get to remake into various geometric visions. You can see more at the website of Kadon Enterprises, Inc. Kadon says that the creation of tiling patterns is an ancient and still very popular art form and recreation. “In quilting designs, floor tiles and wallpaper patterns, we find geometric shapes that fit together in attractive, usually symmetrical arrangements.”

There is a wonderful brochure that comes with each puzzle that explains some of the relationships between the angles and gets into the math of it.

Although I have only pictured two, I hope you can see how multi-faceted this is. I spend many happy hours exploring this and many of their other puzzles.

I used these two shots so you could see the simplest variation. The tiles are acrylic and fit into place perfectly.
