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
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:

“Be Conscientious – An 80-year study found one of the best predictors of a long life is a conscientious personality. Researchers measured attributes like attention to detail and persistence. They found that conscientious people do more things to protect their health and make choices that lead to stronger relationships and better careers. “
As a person who considers himself to be conscientious I was happy to learn that it may be instrumental in my living longer.
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
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?
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.
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.
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
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
As regular readers know, I have a history of Alzheimer’s Disease or some form of dementia on both sides of my family, so I entertain a strong interest in the subject, particularly since I am a senior citizen.
A brain disorder that mimics symptoms of Alzheimer’s disease has been defined with recommended diagnostic criteria and guidelines for advancing future research on the condition. Researchers at Rush University Medical Center and scientists from several National Institutes of Health-funded institutions, in collaboration with international peers, described the newly named pathway to dementia, limbic-predominant age-related TDP-43 encephalopathy, or LATE, in a report published today in the journal Brain.
“We proposed a new name to increase recognition and research for this common cause of dementia, the symptoms of which mimic Alzheimer’s dementia but is not caused by plaques and tangles (the buildup of beta amyloid proteins that Alzheimer’s produces). Rather, LATE dementia is caused by deposits of a protein called TDP-43 in the brain,” said Dr. Julie Schneider, senior author of the Brain paper and associate director of the Rush Alzheimer’s Disease Center.

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
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.

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.
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.
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
I have spent a lot of time writing about the benefits of exercise for the brain as well as the body. Herewith info from the Tufts Health and Nutrition Letter on what I can only call food for thought.
Currently available medical treatments for age-related cognitive decline and Alzheimer’s disease have had limited success. Adopting a healthy diet and lifestyle has been among the most consistent recommendations to maintain brain health over the long term. Some studies have linked an overall healthy dietary pattern to less chance of experiencing age-related decline in memory and other cognitive skills.
The specifics of “brain protective” diets vary, but tend to have certain elements in common. Dietary patterns associated with lower risk of age-related cognitive decline and dementia are higher in non-starchy vegetables, fruits, whole grains, nuts, legumes and seafood while limited in red and/or processed meats, sugar-sweetened foods and drinks, refined grains and added salt.
But there have been few long-term trials testing overall dietary patterns for protecting the aging brain. Researchers at Rush University Medical Center in Chicago and the Harvard T.H. Chan School of Public Health are currently conducting a clinical trial of a diet specifically optimized for brain health and mild weight loss—the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet.
If successful, the result of the MIND trial will provide older adults with more specific nutritional guidance to maintain their cognitive health. “What they’re doing is logical and I predict will have positive benefits for a disease for which we have few interventions,” notes Dennis Steindler, PhD, senior scientist and director of Tufts’ HNRCA Neuroscience and Aging Laboratory. “Past trials were not home runs, but this study could be it if it bears the kind of findings I think it will.” Continue reading
In the nearly 10 years of writing this blog I have come to believe that use it or lose it is an unassailable law of the body. And what applies to the body often carries over to the brain. As I have mentioned previously, my family has dementia in general and Alzheimer’s in particular on both sides, so keeping a clear head really resonates with me.
Keeping physically and mentally active in middle age may be tied to a lower risk of developing dementia decades later, according to a study published in the medical journal Neurology. Mental activities included reading, playing instruments, singing in a choir, visiting concerts, gardening, doing needlework or attending religious services.
“These results indicate that these activities in middle age may play a role in preventing dementia in old age and preserving cognitive health,” said study author Jenna Najar, MD, from Sahlgrenska Academy, University of Gothenburg.
“It’s exciting as these are activities that people can incorporate into their lives pretty easily and without a lot of expense.” Continue reading
Simple, but not easy, is a common description that I seem to hear all the time. I have accumulated some simple, and I hope easy, tips for successful aging. These are from Dana Corp.’s Brain in the News.
1. Be physically active – 30 minutes a day – three days a week. Easy peasy.
2. Reduce your cardiovascular risk factors – including hypertension, diabetes and smoking.
3. Manage your medications by reviewing them with a clinician and learning about their effects on your cognitive health.
4. Be socially and intellectually active.
5. Get enough sleep. I can’t stress this enough. If you want to know more about this utterly simple step, please check out my Page – How important is a good night’s sleep?
6. Guard against delirium, a decrease in cognitive function that can be triggered by hospitalization, medications and certain illnesses.
As I have written here numerous times, both sides of my family have a history of Alzheimer’s Disease, the most common form of dementia. As a guy in his late 70’s this is a critical subject for me. And I am not the only one. I live near Northwestern Memorial Hospital, a major Chicago health establishment. They have a Healthy Transitions program there for folks over 50 which provides programs explaining the changes we are experiencing and can expect to experience. The most popular are the ones dealing with cognitive impairment, Alzheimer’s and dementia. We are all concerned.
That’s why I hope there is a special place in hell for companies who prey on the fears of seniors about their mental health and capacities. I found this item from the U.S. Food and Drug Administration (FDA) most satisfying. Continue reading
General Douglas MacArthur, Paul Newman, Angela Davis, Wayne Gretzky, Eddie Van Halen, Jules Feiffer and Ellen DeGeneres were all born on January 26.
Oh, yes, and one not so famous. It’s also my birthday. I am now 79 years old. I am happy to say that I feel great and am healthier than I was 20 years ago when I was toiling away in the working world.
This is my birthday picture from a while back. It’s the only one I have that’s decorated. Also, my pup is in it, too.
This is from my birthday blog post last year:
One of the main reasons I feel like I have things so together is this blog. I started writing it in March of 2010 with a partner who has since left for other pursuits. From the beginning, I discovered a focus. At first it was simply trying to keep my weight down. I learned portion control and serving size. This Italian guy was surprised to learn that a “serving” of pasta was not a 10 inch plate heaped with spaghetti noodles smothered in tomato sauce. No, a 200 calorie serving of pasta is about the size of a baseball. Incredibly, that was a revelation to me. I put the information to use. I began to reduce my portions accordingly. I am not going to recount all the lessons I learned in the past nearly nine years, but if you want to get control of your weight, check out my Page – How to Lose Weight – and Keep it Off.
