As a guy in his early 80’s working every day on making it into the ’90’s, I found it kind of disturbing that here in the States elders aren’t necessarily held in very high regard.
Elders are more respected in Japan and China and not so much in more individualistic nations like the United States and Germany, say Michigan State University researchers who conclude in a pair of studies that age bias varies among countries and even states.
“Older adults are one of the only stigmatized groups that we all become part of some day. And that’s always struck me as interesting — that we would treat so poorly a group of people that we’re destined to become someday,” said William Chopik, assistant professor of psychology and author of the studies. “Making more equitable environments for older adults are even in younger people’s self-interests.”
Consumption of chili pepper may reduce the relative risk of cardiovascular disease mortality by 26%, according to an analysis of diet and mortality data from four large, international studies.
Chili pepper consumption was associated with a 25% reduction in death from any cause and 23% fewer cancer deaths, compared to people who never or only rarely consumed chili pepper.
Individuals who consume chili pepper may live longer and may have a significantly reduced risk of dying from cardiovascular disease or cancer, according to preliminary research to be presented at the American Heart Association’s Scientific Sessions 2020. The meeting will be held virtually, Friday, November 13-Tuesday, November 17, 2020, and is a premier global exchange of the latest scientific advancements, research and evidence-based clinical practice updates in cardiovascular science for health care worldwide.
The National Institute on Aging and the Alzheimer’s Association are suggesting changes to the research definition of Alzheimer’s disease. There are new criteria to define what Alzheimer’s disease is and who has it — but only as it relates to clinical trials and research, and not the diagnosis in your doctor’s office, according to Jonathan Graff-Radford, M.D. of the Mayo Clinic.
Previously, Alzheimer’s disease dementia was characterized by symptoms such as memory loss and changes in thinking and cognition. And that’s still the case when your doctor diagnoses Alzheimer’s disease dementia.
The brain controls many aspects of thinking — remembering, planning and organizing, making decisions, and much more. These cognitive abilities affect how well we do everyday tasks and whether we can live independently.
Some changes in thinking are common as people get older. For example, older adults may:
Be slower to find words and recall names
Find they have more problems with multitasking
Experience mild decreases in the ability to pay attention
Aging may also bring positive cognitive changes. For example, many studies have shown that older adults have more extensive vocabularies and greater knowledge of the depth of meaning of words than younger adults. Older adults may also have learned from a lifetime of accumulated knowledge and experiences. Whether and how older adults apply this accumulated knowledge, and how the brain changes as a result, is an area of active exploration by researchers.
We may wish some memories could last a lifetime, but many physical and emotional factors can negatively impact our ability to retain information throughout life.
A new study published in the journal Psychological Science found that people who feel enthusiastic and cheerful—what psychologists call “positive affect”—are less likely to experience memory decline as they age. This result adds to a growing body of research on positive affect’s role in healthy aging.
Balance exercises help prevent falls, a common problem in older adults that can have serious consequences, according to the National Institute on Aging (NIA).
Many lower-body strength exercises also will improve your balance. Exercises to improve your balance include Tai Chi, a “moving meditation” that involves shifting the body slowly, gently, and precisely, while breathing deeply.
Examples of balance exercises
Try standing on one foot, then the other. If at first you need support, hold on to something sturdy. Work your way up to doing this movement without support. Get up from a chair without using your hands or arms.
Try the heel-to-toe walk. As you walk, put the heel of one foot just in front of the toes of your other foot. Your heel and toes should touch or almost touch.
Have a sturdy chair or a person nearby to hold on to if you feel unsteady.
Your muscular strength can make a big difference. Strong muscles help you stay independent and make everyday activities feel easier, like getting up from a chair, climbing stairs, and carrying groceries, according to the National Institute on Aging (NIA).
Keeping your muscles strong can help with your balance and prevent falls and fall-related injuries. You are less likely to fall when your leg and hip muscles are strong. Some people call using weight to improve your muscle strength “strength training” or “resistance training.”
Strength exercises include lifting weights, even your own body weight, and using a resistance band.
Better heart health, as measured by the American Heart Association’s Life’s Simple 7 (LS7) scale, was associated with a significantly lower risk of developing high blood pressure (also known as hypertension) in middle-aged, Black and white adults, according to new research published in the Journal of the American Heart Association.
“High blood pressure is among the most common conditions in the U.S., and it contributes to the greatest burden of disability and largest reduction in healthy life expectancy among any disease,” said Timothy B. Plante, M.D., M.H.S., lead study author and assistant professor in the department of medicine at the Larner College of Medicine at the University of Vermont in Burlington. “Even though high blood pressure causes so much death and disability, we don’t know the root cause of it.”
Free, circulating Vitamin D levels in the blood may be a better predictor of future health risks in aging men, according to a study being presented at e-ECE 2020. These data suggest the free, precursor form of vitamin D found circulating in the bloodstream is a more accurate predictor of future health and disease risk, than the often measured total Vitamin D. Since Vitamin D deficiency is associated with multiple serious health conditions as we get older, this study suggests that further investigation into Vitamin D levels and their link to poor health may be a promising area for further research.
Vitamin D deficiency is common in Europe, especially in elderly people. It has been associated with a higher risk for developing many aging-related diseases, such as cardiovascular disease, cancer and osteoporosis. However, there are several forms, or metabolites, of Vitamin D in the body but it is the total amount of these metabolites that is most often used to assess the Vitamin D status of people. The prohormone, 25-dihydroxyvitamin D is converted to 1,25-dihydroxyvitamin D, which is considered the active form of vitamin D in our body. More than 99% of all Vitamin D metabolites in our blood are bound to proteins, so only a very small fraction is free to be biologically active. Therefore the free, active forms may be a better predictor of current and future health.
As we age, the strength and size of our muscles tend to decrease. This loss of muscle mass and function, called sarcopenia, is associated with decreased independence and reduced quality of life. Staying active (and purposefully incorporating muscle-strengthening exercises) is essential, but emerging data suggest that nourishing our gut microbes could be important as well.
The Gut-Muscle Connection: The trillions of bacteria and other microbes that live in our guts are intimately intertwined with our metabolism. These microscopic inhabitants play roles in digestion, nutrient absorption, and amino acid synthesis, and are also involved in maintaining the integrity of the intestinal lining so invading organisms, unwanted food components, and the wrong microbial products cannot slip through. Studying the role of the gut microbiome in health is challenging, but research suggests that the make-up of our personal inner world of tiny organisms could play a role in our risk for a number of common diseases and conditions, including obesity, diabetes, and cardiovascular disease. “Emerging research in mice and preliminary human studies suggest there may also be a connection between our gut microbiome and our muscles,” says Michael Lustgarten, PhD, a scientist in the Nutrition, Exercise Physiology, and Sarcopenia laboratory at the Human Nutrition Research Center on Aging.
A new analysis published in the journal Psychological Science in the Public Interest (PSPI), however, reveals that even though a more extensive formal education forestalls the more obvious signs of age-related cognitive deficits, it does not lessen the rate of aging-related cognitive declines. Instead, people who have gone further in school attain, on average, a higher level of cognitive function in early and middle adult adulthood, so the initial effects of cognitive aging are initially less obvious and the most severe impairments manifest later than they otherwise would have.
“The total amount of formal education that people receive is related to their average levels of cognitive functioning throughout adulthood,” said Elliot M. Tucker-Drob, a researcher with the University of Texas, Austin, and coauthor on the paper. “However, it is not appreciably related to their rates of aging-related cognitive declines.”Continue reading →
The National Institute on Aging offered the following infographic on living a healthy and long life. There is nothing new in it, but I think it is good to see simple rules like this that we all know and refresh them in our minds.
Cognitive decline is a major concern of the aging population. Already, Alzheimer’s disease affects approximately 5.4 million Americans and 30 million people globally. Without effective prevention and treatment, the prospects for the future are bleak. By 2050, it is estimated that 160 million people globally will have the disease, including 13 million Americans, leading to potential bankruptcy of the Medicare system. Unlike several other chronic illnesses, Alzheimer’s disease is on the rise–recent estimates suggest that Alzheimer’s disease has become the third leading cause of death in the United States behind cardiovascular disease and cancer. Since its first description over 100 years ago, Alzheimer’s disease has been without effective treatment.
While researchers continue to seek out a cure, it is becoming clear that there are effective treatment options. More and more research supports the conclusion that Alzheimer’s disease is not a disease of only Beta Amyloid plaques and Tao tangles but a complex and systemic disease. In this study of patients with varying levels of cognitive decline, it is demonstrated how a precision and personalized approach results in either stabilization or improvement in memory.
Affirmativ Health sought to determine whether a comprehensive and personalized program, designed to mitigate risk factors of Alzheimer’s disease could improve cognitive and metabolic function in individuals experiencing cognitive decline. Findings provided evidence that this approach can improve risk factor scores and stabilize cognitive function.
People with lower household wealth (or socioeconomic status) have a higher risk of many diseases, including heart disease, diabetes, and depression. They also have shorter lifespans. Some lifestyle factors may play a role. For example, people with lower incomes have higher rates of smoking. However, other factors—including chronic stress and reduced access to resources—also likely contribute, according to the National Institute on Aging (NIA).
Less is known about how socioeconomic status influences the general aging process. To look more closely at this question, Drs. Andrew Steptoe and Paola Zaninotto from University College London followed more than 5,000 adults, aged 52 and older, for 8 years beginning in 2004. The team broke the study participants into four groups based on household wealth. Continue reading →
Do you know that feeling you get in your gut? It turns out your gut may really be trying to tell you something. Our microbiome – the 100 trillion bacteria and organisms living in our gut – appears to have a profound influence on our health and risk of disease. And early scientific studies show there may be a link between the microbiome and the brain that could impact the risk of Alzheimer’s and other brain diseases.
The microbiome is a collection of bacteria, viruses and fungi that live mostly in our intestinal system. They play an important role in digestion and the production of certain vitamins, and they support our immune system. Researchers around the world study the gut microbiome, especially those bacteria unique to individuals, to learn more about their influence on our overall health.
It’s never too late to lace up some sneakers and work up a sweat for brain health, according to a study published in the May 13, 2020, online issue of Neurology®, the medical journal of the American Academy of Neurology. The study suggests older adults, even couch potatoes, may perform better on certain thinking and memory tests after just six months of aerobic exercise.
“As we all find out eventually, we lose a bit mentally and physically as we age. But even if you start an exercise program later in life, the benefit to your brain may be immense,” said study author Marc J. Poulin, Ph.D., D.Phil., from the Cumming School of Medicine at the University of Calgary in Alberta, Canada. “Sure, aerobic exercise gets blood moving through your body. As our study found, it may also get blood moving to your brain, particularly in areas responsible for verbal fluency and executive functions. Our finding may be important, especially for older adults at risk for Alzheimer’s and other dementias and brain disease.”
