Chocolate may improve cognitive function within hours – Study

Here is some good news for chocolate lovers. Researchers have found that cocoa flavanols could boost cognitive function within just a few hours of consumption. Perhaps the best news is that elderly adults reaped the best benefits.

Additionally, researchers found that regular, long-term intake of cocoa flavanols may protect against cognitive decline.

Tea drinking may help prevent dementia – Harvard

Good news for tea drinkers or all stripes. A study in the December 2016 Journal of Nutrition, Health & Aging showed that drinking tea frequently is associated with a lower risk of dementia, especially for people who are genetically predisposed to the disease, Harvard Men’s Health Watch reported.

Researchers followed 957 older adults, average age 65, who were part of the Singapore Longitudinal Aging Study. Of these, 69% drank tea on a frequent basis. After a five-year period, the researchers found that the tea drinkers had a 50% lower risk of dementia. This is consistent with earlier findings that showed tea consumers scored higher on various cognitive tests.

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

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.”

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.

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.

Facts about seniors drinking

What we put into our system counts a lot toward our daily health and ultimate longevity. So, I  thought this study on increasing seniors drinking was relevant.

Most older Americans drink alcohol. Given that this segment of the population is projected to almost double by 2050, reaching 112 million, in the future, there will likely be many more older drinkers in the United States than currently. Importantly, older individuals are more sensitive to alcohol’s effects than their younger counterparts, and are also more likely to take prescription medications that can interact negatively with alcohol, potentially leading to falls and other injuries. This study examined trends in drinking status among U.S. adults 60 years of age and older.

recommandation_alcool_ang_v2-1.jpg

Researchers analyzed data from the 1997-2014 National Health Interview Surveys: 65,303 respondents 60 years of age and older (31,803 men, 33,500 women) were current drinkers; 6,570 men and 1,737 women were binge drinkers. Analysis of respondents by sex, age group, and birth cohort showed differing trends over time. Continue reading

Seniors, It’s not your ears, it’s your brain … Study

I turned 77 in January and while I generally enjoy what I consider to be robust good health, I nonetheless occupy an old and aging body. Sometimes I miss stuff people say, particularly when there is background noise.

“Could you repeat that?” The reason you may have to say something twice when talking to older family members may not be because of their hearing. Researchers at the University of Maryland (UMD) have determined that something is going on in the brains of typical older adults that causes them to struggle to follow speech amidst background noise, even when their hearing would be considered normal on a clinical assessment.

Normal_Hearing.jpg

In an interdisciplinary study published by the Journal of Neurophysiology, researchers Samira Anderson, Jonathan Z. Simon, and Alessandro Presacco found that adults aged 61–73 with normal hearing scored significantly worse on speech understanding in noisy environments than adults aged 18–30 with normal hearing. The researchers are all associated with the UMD’s Brain and Behavior Initiative. Continue reading

Researchers Uncover New Agents That Eliminate Cells Tied to Age-Related Diseases – Mayo Clinic

Mayo Clinic researchers have uncovered three new agents to add to the emerging repertoire of drugs that aim to delay the onset of aging by targeting senescent cells – cells that contribute to frailty and other age-related conditions. A recent study of human cell cultures shows that the drugs, fisetin and two BCL-XL inhibitors – A1331852 and A1155463 – cleared senescent cells in vitro. Findings appear online in Aging.

“Senescent cells accumulate with age and at sites of multiple chronic conditions, such as in fat tissue in diabetes, the lungs in chronic pulmonary diseases, the aorta in vascular disease, or the joints in osteoarthritis,” says James Kirkland, M.D., Ph.D., director of the Robert and Arlene Kogod Center on Aging. “At Mayo Clinic, we discovered the first senolytic drugs – agents that selectively eliminate senescent cells while leaving normal cells unaffected. These senolytic agents alleviated a range of age- and disease-related problems in mice. We used the hypothesis-driven approach that we used to discover the first senolytic drugs, two published in early 2015 and another later in 2015, to discover these three new senolytic drugs.” Continue reading

Delirium could accelerate dementia-related mental decline

It ain’t easy being green, according to Kermit. Turns out it ain’t so easy being old either.

New research by UCL and University of Cambridge shows delirium may have long-lasting consequences, including accelerating the dementia process

brain-sleep-wake-neurosciencenews-public

When hospitalized, people can become acutely confused and disorientated. This condition, known as delirium, affects a quarter of older patients and new research by UCL and University of Cambridge shows it may have long-lasting consequences, including accelerating the dementia process.

The study, published today in the journal JAMA Psychiatry, is the first to show the multiplying effects of delirium and dementia in these patients.

Episodes of delirium in people who are not known to have dementia, might also reveal dementia at its earliest stages, the research found.

While both delirium and dementia are important factors in cognitive decline among the elderly, delirium is preventable and treatable through dedicated geriatric care.

Further research is needed to understand exactly how delirium interacts with dementia, and how this could be blocked.

“If delirium is causing brain injury in the short and long-term, then we must increase our efforts to diagnose, prevent and treat delirium. Ultimately, targeting delirium could be a chance to delay or reduce dementia” said Dr. Daniel Davis (MRC Unit for Lifelong Health and Ageing at UCL), who led the research while at the University of Cambridge.

Scientists looked at three European populations – in Finland, Cambridge and UK-wide – and examined brain specimens in 987 people aged 65 and older. Each person’s memory, thinking and experience of delirium had been recorded over 10 years towards the end of their life.

When these were linked with pathology abnormalities due to Alzheimer’s and other dementias, those with both delirium and dementia-changes had the most severe change in memory.

Dr Davis added: “Unfortunately, most delirium goes unrecognized. In busy hospitals, a sudden change in confusion not be noticed by hospital staff. Patients can be transferred several times and staff often switch over – it requires everyone to ‘think delirium’ and identify that a patient’s brain function has changed.”

Seniors need to get out of that comfort zone – NYT

I have written several posts on why people are discounting in the mainstream media regarding their second rate and slanted coverage of Donald Trump and the recent election. However, I want to point out that this piece from the New York Times is superb reporting. So, the grey lady lives on.

The article was How to become a Superager by Lisa Feldman Barrett. She is the author of the forthcoming “How Emotions Are Made: The Secret Life of the Brain.”

82f56d64ae0f0ceede3ec8853681bfcb

She asks, “Why do some older people remain mentally nimble while others decline? “Superagers” (a term coined by the neurologist Marsel Mesulam) are those whose memory and attention isn’t merely above average for their age, but is actually on par with healthy, active 25-year-olds. ”

In providing the answer, she gets into some labyrinthine details on how the brain functions. If you want to go there just click on the link to the article and enjoy. Continue reading

Seniors’ brains benefit from distraction – Study

While I want to live past 100, I also want to have my brain fully functional. So, any piece of information that satisfies that criterion, is music to my ears.

As you age, you may find it more difficult to focus on certain tasks. But while distractions can be frustrating, they may not be as bad as we think. In a review published November 15 in Trends in Cognitive Sciences, researchers at the University of Toronto and Harvard University suggest that there may be some benefits to reduced focus, especially in people over 50. Using behavioral studies and neuroimaging evidence, the researchers discuss how being easily distracted can help adults with, for example, problem solving and learning new information.

brain-sleep-wake-neurosciencenews-public

“Different types of tasks benefit from a more broad focus of attention, and this is usually seen in tasks that involve thinking creatively or using information that was previously irrelevant,” says first author Tarek Amer, a psychology Ph.D. candidate at the University of Toronto and a graduate student at the Rotman Research Institute. “The literature gives us the impression that older adults are essentially doomed as their cognitive abilities decrease, when, in reality, many older adults get along just fine in their day-to-day lives, and we think that shows that aging adults don’t always need to have high cognitive control.”

When people have high cognitive control, they are able to maintain their focused attention and ignore distractions to get things done. But Amer and his colleagues found that people with reduced cognitive control had an easier time thinking of creative solutions to problems, and they were better at noticing patterns in the world around them. These findings also indicated that older adults could outperform their younger counterparts on certain problem-solving tasks, as they were able to broaden their attention more easily. Additionally, people didn’t require high levels of cognitive control for inherent, day-to-day tasks, like walking down the street or learning new information.

In order to explore the benefits of cognitive control, many lab-based behavioral experiments require participants to complete a specific set of tasks, limiting the role of distraction. But the researchers say these experiments have shortcomings, as they don’t explore situations when distractions and reduced cognitive control could be helpful, making the conclusions fairly one sided.

“Many of the tasks that we study in classic cognitive psychology are tasks that require high cognitive control, but these assigned tasks might not accurately mirror what people do in the real world because they limit distractions,” says co-author Lynn Hasher, a professor of psychology at the University of Toronto and the Rotman Research Institute. “But a distraction in one setting can actually be useful information in another setting, and the more information you have, the better able you’re going to be to address a current problem.”

Amer and his colleagues hope to use this information to determine exactly what tasks can benefit from reduced control in order to better simulate these experiences in a lab. Although they also hope to expand the research beyond the aging population to examine how distractions can be beneficial for people with a range of cognitive impairments, for now they recognize that this understanding of cognitive control is a step closer to understanding the aging brain.

“There is a question about what really sustains performance in old age, and it’s clear that working memory alone cannot provide us with the answer to that question,” says Hasher. “But we think it’s possible that studying reduced cognitive control can help us understand how older adults can still perform independently and successfully in their lives.”

Aerobic Exercise Preserves Brain Volume / Improves Cognition – RSNA

I seem to remember a line from a Clint Eastwood movie – Go ahead, make my day.  That’s how I feel every time I read something in the press about how exercise helps the brain the function better. It absolutely makes my day.

This is from the Radiological Society of North America (RSNA):

•    Aerobic exercise may increase brain volume and cognitive function in people with mild cognitive impairment.
•    MRI results showed increased local gray matter volume in patients who engaged in either aerobic or stretching exercises for six months, but some white matter atrophy in the stretching group.
•    Cognitive testing revealed the aerobic exercise group also showed improvement in executive function after six months.

brainexercise.jpg

Using a new MRI technique, researchers found that adults with mild cognitive impairment (MCI) who exercised four times a week over a six-month period experienced an increase in brain volume in specific, or local, areas of the brain, but adults who participated in aerobic exercise experienced greater gains than those who just stretched. The study was presented at the annual meeting of the Radiological Society of North America (RSNA). Continue reading

Heart disease and brain health linked – Harvard

I have written time and again about the link between exercise and brain health. The Harvard Heart Letter has a nice post on how heart disease and brain health are tied together.

“Just like in the rest of your body, advancing years can take a toll on your brain function. Much of this slowing down is predictable and can be chalked up to normal aging. However, when thinking skills become increasingly fuzzy and forgetfulness gets to be a way of life, an early form of dementia known as mild cognitive impairment may be setting in,” so writes Julie Corliss, Executive Editor, Harvard Heart Letter.

brainbenefits-01-1

“Often, the first reaction is to attribute these changes to the beginning of Alzheimer’s disease. But blood flow problems may be to blame, as well. “An estimated one-third of all cases of dementia, including those identified as Alzheimer’s, can be attributed to vascular factors,” says Dr. Albert Hofman, chair of the department of epidemiology at the Harvard T.H. Chan School of Public Health. Continue reading

80-year old reshaping views of aging in China

In this blog devoted to living a long healthy life with a fully functional brain at the end, I just had to share this news item on “China’s hottest grandpa.”

Here is a link to the article in today’s New York Times.

I never thought I would be offering you a video with Chinese as the spoken language, but there is a sub-titled translation below it and you will have a chance to meet the sparkling Mr. Deshun for yourself.

“Determined to avoid mental and physical stagnation, Mr. Wang has explored new skills and ideas while devoting ample time to daily exercise. Last year, he walked the runway for the first time, his physique causing a national sensation. He takes obvious joy in subverting China’s image of what it means to be old,” Didi Kirsten Tatlow wrote in the Times.

I was not aware that old age in China begins relatively early. “The legal retirement age for women is 50 for workers and 55 for civil servants, and 60 for most men.”

Besides his healthy mental outlook, he carries on his avid interest in swimming managing a half mile a day. (my emphasis)

He says that he is not picky about food. He eats whatever he wants. Clearly, he is making good choices to be in such wonderful condition.
