10 Brain-saving techniques – Alzheimer’s Association

As regular readers know, I am very sensitive to cognitive impairment, having lost three close family members to Alzheimer’s and dementia. So I was very happy to come across this list of recommendations for building up our mental muscles and reducing our chances of contracting Alzheimer’s from the Alzheimer’s Association.

dementia

“Research on cognitive decline is still evolving,” said Theresa Hocker, president and CEO of the Alzheimer’s Association – North Central Texas Chapter. “But there are actions people can take. Certain healthy behaviors known to combat cancer, cardiovascular disease and diabetes also may reduce the risk of cognitive decline. These include staying mentally active, engaging in regular physical activity, and eating a heart-healthy diet that benefits your body and your brain.”

1. Break a sweat. Engage in regular cardiovascular exercise that elevates your heart rate and increases blood flow to the brain and body. Several studies have found an association between physical activity and reduced risk of cognitive decline.

2. Hit the books. Formal education in any stage of life will help reduce your risk of cognitive decline and dementia. For example, take a class at a local college, community center or online.

3. Butt out. Evidence shows that smoking increases risk of cognitive decline. Quitting smoking can reduce that risk to levels comparable to those who have not smoked. Continue reading

Diets rich in blueberries yield diverse benefits

A collection of new studies in The Journals of Gerontology, Series A: Biological Sciences and Medical Sciences further quantifies how blueberry consumption can contribute to healthy aging.

“Since the 1990s, research on the health benefits of blueberries has grown exponentially,” wrote guest editor Donald K. Ingram, PhD, FGSA, in an opening editorial. “Studies have documented that this fruit ranks highest in antioxidant activity compared to many other popular fruits. Moreover, other mechanisms for the health benefits of blueberries, such as their anti-inflammatory properties, have been identified.”

Ingram’s editorial is followed by four articles in a special section of the journal’s Biological Sciences section. One of the studies found that consuming 200 grams of blueberries (about one cup) daily can improve blood vessel function and decrease systolic blood pressure. As the cause, the authors cited anthocyanins, which are phytochemicals that give blueberries their dark color.

Other studies document the cognitive benefits of eating blueberries. One tied the fruit’s high polyphenol count to improved performance on memory tests by a group of older adults. Likewise, another journal article provides a review of several clinical studies focusing on benefits of blueberry supplementation — with a focus on specific memory effects in children as well as older adults with mild cognitive impairment.

The journal collection also includes a rodent study, which presents data on the improved memory performance of blueberry-supplemented aged rats compared to rats on a control diet.

Left brain vs right brain …

The human brain fascinates me for lots of reasons. I have taken several courses in it from The Great Courses and recommend them for anyone curious about this amazing organ that lives inside our heads. I have written a number of posts on various aspects of the brain which I recommend your chasing down. Just type in b r a i n into the SEARCH BOX at the right. Also, you can check out my Page – Important facts about your brain (and exercise benefits). Last, but not least, of course, there is the specter of dementia in general and Alzheimer’s Disease, in particular. I have lost three family members to these afflictions and, at the age of 79, I am very focused on my mental functions. Which brings us to this wonderful article in Medical News Today on the two hemispheres of the brain – the left and the right.

brain

The two hemispheres or sides of the brain have slightly different jobs. But can one side be dominant and does this affect personality?

Some people believe that a person is either left-brained or right-brained and that this determines the way they think and behave.

In this article, we explore the truth and fallacy behind this claim. Read on to learn more about the functions and characteristics of the left and right brain. Continue reading

Some dementia patients show moments of clarity at end of life – Study

It happens unexpectedly: a person long thought lost to the ravages of dementia, unable to recall the events of their lives or even recognize those closest to them, will suddenly wake up and exhibit surprisingly normal behavior, only to pass away shortly thereafter. This phenomenon, which experts refer to as terminal or paradoxical lucidity, has been reported since antiquity, yet there have been very few scientific studies of it. That may be about to change.

In an article published in the August issue of Alzheimer’s & Dementia , an interdisciplinary workgroup convened by the National Institutes of Health’s (NIH) National Institute on Aging and led by Michigan Medicine’s George A. Mashour, M.D., Ph.D., outlines what is known and unknown about paradoxical lucidity, considers its potential mechanisms, and details how a thorough scientific analysis could help shed light on the pathophysiology of dementia.

Teeth brushing may fight Alzheimer’s

As a person with no less than three cases of Alzheimer’s/dementia in his family, I have serious interest in anything relating to maintaining brain health and function. So, I was most interested in this item from the University of Bergen.

You don’t only avoid holes in your teeth by keeping good oral hygiene, researchers at the University of Bergen have discovered a clear connection between gum disease and Alzheimer’s disease.

The researchers have determined that gum disease (gingivitis) plays a decisive role in whether a person develops Alzheimer’s or not.

“We discovered DNA-based proof that the bacteria causing gingivitis can move from the mouth to the brain,” says researcher Piotr Mydel at Broegelmanns Research Laboratory, Department of Clinical Science, University of Bergen (UiB).

The bacteria produces a protein that destroys nerve cells in the brain, which in turn leads to loss of memory and ultimately, Alzheimer’s. Continue reading

Tips on living a longer life – WebMD

Regular readers know that I am a big fan of WebMD. I often quote from them to share ideas with readers. They have just run an item on living longer that has some wonderful suggestions. By no small coincidence, I have also included many of the same suggestions in this blog over the past nine plus years. However, here are a few that were new to me:

Reaching and grasping — Learning fine motor coordination changes the brain

When we train the reaching for and grasping of objects, we also train our brain. In other words, this action brings about changes in the connections of a certain neuronal population in the red nucleus, a region of the midbrain. Researchers at the University of Basel’s Biozentrum have discovered this group of nerve cells in the red nucleus. They have also shown how fine motor tasks promote plastic reorganization of this brain region. The results of the study have been published recently in Nature Communications.

Simply grasping a coffee cup needs fine motor coordination with the highest precision. This required performance of the brain is an ability that can also be learned and trained. Prof. Kelly Tan’s research group at the Biozentrum, University of Basel, has investigated the red nucleus, a region of the midbrain that controls fine motor movement, and identified a new population of nerve cells which changes when fine motor coordination is trained. The more that grasping is practiced, the more the connections between the neurons of this group of nerve cells are strengthened. Continue reading

How to boost brain health and fight Alzheimer’s

At the risk of being repetitious, I just wanted to pass along some good information on keeping your brain intact while you are pursuing a life of healthy eating and regular exercise. That’s why you’re reading this blog, right?

Screen Shot 2019-06-02 at 7.23.43 AM.png

The seven guidelines to reduce risk of Alzheimer’s disease are:

  • Minimize your intake of saturated fats and trans fats. Saturated fat is found primarily in dairy products, meats, and certain oils (coconut and palm oils). Trans fats are found in many snack pastries and fried foods and are listed on labels as “partially hydrogenated oils.”
  • Eat plant-based foods. Vegetables, legumes (beans, peas, and lentils), fruits, and whole grains should replace meats and dairy products as primary staples of the diet.
  • Consume 15 milligrams of vitamin E, from foods, each day. Vitamin E should come from foods, rather than supplements. Healthful food sources of vitamin E include seeds, nuts, green leafy vegetables, and whole grains. Note: The RDA for vitamin E is 15 milligrams per day.
  • Take a B12 supplement. A reliable source of B12, such as fortified foods or a supplement providing at least the recommended daily allowance (2.4 micrograms per day for adults), should be part of your daily diet. Note: Have your blood levels of vitamin B12 checked regularly as many factors, including age, impair absorption.
  • Avoid vitamins with iron and copper. If using multivitamins, choose those without iron and copper, and consume iron supplements only when directed by your physician.
  • Choose aluminum-free products. While aluminum’s role in Alzheimer’s disease remains a matter of investigation, those who desire to minimize their exposure can avoid the use of cookware, antacids, baking powder, or other products that contain aluminum.
  • Exercise for 120 minutes each week. Include aerobic exercise in your routine, equivalent to 40 minutes of brisk walking, three times per week.

Other preventive measures, such as getting a minimum of seven hours of sleep each night and participating in 30 to 40 minutes of mental activity most days of the week, such as completing crossword puzzles, reading the newspaper, or learning a new language, can only help boost brain health.

Before you leave, just wanted to pass on a reminder about my Page – Important facts about your brain – and exercise benefits.

How do you feel about aging?

Asking your opinion on aging is not just an idle query. Does aging mean decline and disability to you? Or do you consider aging to be a time of opportunity and growth?

According to the Wall Street Journal, your attitude about aging plays a key role in how well you actually experience getting older.

“In test after test, researchers are finding that if we think about getting older in terms of decline or disability, our health likely will suffer. If, on the other hand, we see aging in terms of opportunity and growth, our bodies respond in kind,” Anne Tergesen wrote in the WSJ.

d0b979b503d89f99664cd782d8605c57

The good news is that there is a real physical and mental upside to aging with positive attitudes. On the other hand, negative stereotypes which are pervasive in America can do serious harm to all concerned. Continue reading

Does solo living raise mental health risk?

Full disclosure. I am a senior who lives alone. I do have a girlfriend and a dog whom I consider to be constant companions, so that may temper the damage of living solo as reported by Medical News Today.

A new study has concluded that living alone is linked to common mental disorders. The authors have also identified the main driver of this worrying relationship.

Some common mental disorders (CMDs) include mood disorders, anxiety, and substance use disorders.

According to some studies, almost one-third of people will experience a CMD in their lifetime.

These conditions can have a significant impact on the individual, of course, but due to their high prevalence, they also affect society at large.

Due to the widespread influence of CMDs, scientists are keen to understand the full range of risk factors that feed into mental health.

In recent years, scientists have investigated whether living alone might be one such risk factor. Continue reading

Creativity is not just for the young – study

If you believe that great scientists are most creative when they’re young, you are missing part of the story.

A new study of winners of the Nobel Prize in economics finds that there are two different life cycles of creativity, one that  hits some people early in their career and another that more often strikes later in life.

In this study, the early peak was found for laureates in their mid-20s and the later peak for those in their mid-50s.

The research supports previous work by the authors that found similar patterns in the arts and other sciences.

“We believe what we found in this study isn’t limited to economics, but could apply to creativity more generally,” said Bruce Weinberg, lead author of the study and professor of economics at The Ohio State University. Continue reading

Is it possible to supercharge memories back to life? – BU Study

As a 79 year old bike rider, I know how much I am counting on exercise to keep my brain intact as I age. So, I was nothing less than amazed to run across the Boston University (BU) study on electrically stimulating brain function in seniors.

BU brain scientist shows electrostimulation can restore a 70-year-old’s working memory to that of a 20-year-old.

As you read the words stretched across this page, your brain is doing something magnificent. Each sentence lingers in your mind for a fleeting moment, the letters melding into a symphony of neural signals. These intricate electrical rhythms form the language of the brain, a language we have only begun to understand within the last century.

Rob Reinhart, an assistant professor of psychological and brain sciences at Boston University, says we’ve reached a point where we not only understand this language—we can speak it and harness it to enhance the functioning of the mind. In a groundbreaking study published April 2019 in Nature Neuroscience, Reinhart and BU doctoral researcher John Nguyen demonstrate that electrostimulation can improve the working memory of people in their 70s so that their performance on memory tasks is indistinguishable from that of 20-year-olds.

Reinhart and Nguyen’s research targets working memory—the part of the mind where consciousness lives, the part that is active whenever we make decisions, reason, recall our grocery lists, and (hopefully) remember where we left our keys. Working memory starts to decline in our late 20s and early 30s, Reinhart explains, as certain areas of the brain gradually become disconnected and uncoordinated. By the time we reach our 60s and 70s, these neural circuits have deteriorated enough that many of us experience noticeable cognitive difficulties, even in the absence of dementias like Alzheimer’s disease.

Brain health connects to heart health – CDC

Eat less; move more; live longer is the mantra here. Apparently, it also leads to think better, too. The Centers for Disease Control and Prevention (CDC) seems to think so.

Did you know that the health of your brain and your heart are connected? By keeping your heart healthy, you also lower your risk for brain problems such as stroke and dementia. Learn more about the connection between the heart and brain and steps to take to keep both healthy.

Heart disease, stroke, and vascular dementia are preventable. Take steps to reduce your risk.

 

  • Control your blood pressure. High blood pressure is a leading cause of heart disease and stroke. Over time, high blood pressure puts too much stress on blood vessels. Scientists now know that having uncontrolled high blood pressure in midlife also raises your risk for dementia later in life. Know your numbers by getting your blood pressure checked regularly. If your blood pressure is high, work with your doctor, nurse, or health care team to manage it. One way to manage your blood pressure is to take your medicines as prescribed. Learn more ways to manage blood pressure.
  • Eat healthy foods and limit alcohol. Eat plenty of vegetables, fruits, whole grains, and low-fat dairy, and include seafood rich in omega-3 fatty acids (such as salmon) each week. Limit foods with added sugars and saturated fats, and lower your sodium (salt) intake. If you drink alcohol, drink in moderation. Drinking too much alcohol raises blood pressure, which can lead to stroke and increase the risk of some kinds of heart disease.
  • Get diabetes under control. Diabetes causes high blood sugar, which can damage blood vessels and nerves. This damage raises the risk for heart disease, stroke, and dementia.
  • Don’t smoke. Smoking damages blood vessels and makes blood more likely to clot, which can lead to heart disease and stroke. Smoking is the leading cause of preventable death in the United States. If you don’t smoke, don’t start. If you do smoke, learn how to quit.
  • Stay active. Lack of physical activity can lead to high blood pressure and obesity. Most Americans don’t meet guidelines of getting at least 150 minutes of moderate-intensity exercise each week. Find ways to get your heart pumping for at least 150 minutes per week. Take the stairs, schedule a walk at lunch, or do jumping jacks during commercial breaks. Learn more about how to get enough physical activity.

Physics explains why time flies as we age

Time flies when you’re having fun. As an old timer, I have responded countless times that “Time flies even when you’re not having fun.” So I was most gratified to find this research on exactly that.

A Duke University researcher has a new explanation for why those endless days of childhood seemed to last so much longer than they do now–physics.

According to Adrian Bejan, the J.A. Jones Professor of Mechanical Engineering at Duke, this apparent temporal discrepancy can be blamed on the ever-slowing speed at which images are obtained and processed by the human brain as the body ages.

Screen Shot 2019-03-21 at 5.06.54 PM.png

The end result is that, because older people are viewing fewer new images in the same amount of actual time, it seems to them as though time is passing more quickly. 

The theory was published online on March 18 in the journal European Review. Continue reading
