Active Social Life May Preserve Memory and Slow Brain Aging

Eat less; move more; live longer remains the mantra of this blog. However, according to this latest study from Ohio State University – interact with friends more – might also be added.

A new study reveals a positive link between socializing, improved memory and a reduced rate of brain aging in mice. Mice who were housed in pairs showed less sings of inflammation and tissue erosion in the hippocampus, researchers report.

New research from The Ohio State University found that mice housed in groups had better memories and healthier brains than animals that lived in pairs.

social-memory-brain-aging-neurosciencenews-public.jpg

The discovery bolsters a body of research in humans and animals that supports the role of social connections in preserving the mind and improving quality of life, said lead researcher Elizabeth Kirby, an assistant professor of behavioral neuroscience and member of the Center for Chronic Brain Injury at Ohio State.

“Our research suggests that merely having a larger social network can positively influence the aging brain,” said Kirby, who is a member of the Neurological Institute at Ohio State’s Wexner Medical Center. Her research appears in the journal Frontiers in Aging Neuroscience.

“We know that in humans there’s a strong correlation between cognitive health and social connections, but we don’t know if it’s having a group of friends that’s protecting people or if it’s that people with declining brain health withdraw from their human connections,” Kirby said.

This study was designed to answer that hard-to-crack question with an animal model.

Some mice lived in pairs, which Kirby refers to as the “old-couple model.” Others were housed for three months with six other roommates, a scenario that allows for “pretty complex interactions.”

The mice were 15 months to 18 months old during the experiment – a time of significant natural memory decline in the rodent lifespan.

“It’s like mouse post-retirement age. If they drove, they’d be forgetting where the keys are or where they parked the car more often,” Kirby said.

In tests of memory, the group-housed mice fared better.

One test challenged the mice to recognize that a toy, such as a plastic car, had moved to a new location. A mouse with good brain health will gravitate toward the novelty of something that has been relocated.

“With the pair-housed mice, they had no idea that the object had moved. The group-housed mice were much better at remembering what they’d seen before and went to the toy in a new location, ignoring another toy that had not moved,” Kirby said.

In another common maze-based memory test, mice are placed on a well-lit round table with holes, some of which lead to escape hatches. Their natural tendency is to look for the dark, unexposed and “safe” escape routes.

Both groups of mice improved their escape-route search strategies with practice – but the research team was struck by the differences in the groups’ response to repeated tests, Kirby said.

The “couples” mice didn’t get faster at the test when it was repeated over the course of a day.

“But over the course of many days, they developed a serial-searching strategy where they checked every hole as quickly as possible. It’d be like walking as quickly as possible through each row of a parking lot to look for your car rather than trying to remember where your car actually is and walk to that spot,” Kirby said.

The group-housed mice improved with each trial, though.

“They seemed to try to memorize where the escape hatches are and walk to them directly, which is the behavior we see in healthy young mice,” Kirby said. “And that tells us that they’re using the hippocampus, an area of the brain that is really important for good memory function.”

The serial searching employed by the pair-housed mice is simpler, easier and doesn’t use that part of the brain, she said.

In humans, mice and many other animals, brain function in the hippocampus markedly declines with age, even in the absence of dementia. Exercise and social ties are known to preserve memory in this region in people, Kirby said.

After the housing experiment, the researchers examined the brain tissue of the mice and found increased inflammation in the pair-housed mice – biological evidence of eroded cognitive health.

“The group-housed mice had fewer signs of this inflammation, meaning that their brains didn’t look as ‘old’ as those that lived in pairs,” Kirby said.

The researchers also looked for evidence of new neuron growth in the hippocampus and found no differences between the groups.

Previous research in this area has primarily focused on mice that have highly enriched environments with lots of toys and opportunities for exercise and compared them with mice without as much to do.

This study goes further by showcasing differences that appear to be due to socialization alone, Kirby said. Future research should explore the molecular explanations for the connection between socialization and improved memory and brain health, she said.

Kirby said that people who are aging would do well to consider how their choices about where to live might impact their ability to be social.

“Something as basic as how long it takes to drive or walk to a friend’s house can make a big difference as we get older,” she said.

“A lot of people end up isolated not by choice, but by circumstance. ‘Over the river and through the woods’ might be fun for the kids, but it’s probably not so great for Grandma,” Kirby said.

Sitting is Bad for Your Brain, Not Just Your Heart or Metabolism

It’s been a couple of years now since I first learned the dangers of prolonged sitting. Someone even called ‘sitting the new smoking.‘ I thought that might have been excessive – might have been. However, this new information from UCLA researchers certainly adds resonance to the problem for seniors.

sitting-brain-health-neuroscienccenews-public.jpg

 

Sitting too much is linked to changes in a section of the brain that is critical for memory, according to a preliminary study by UCLA researchers of middle-aged and older adults.

Studies show that too much sitting, like smoking, increases the risk of heart disease, diabetes and premature death. Researchers at UCLA wanted to see how sedentary behavior influences brain health, especially regions of the brain that are critical to memory formation.

METHOD

UCLA researchers recruited 35 people ages 45 to 75 and asked about their physical activity levels and the average number of hours per day they spent sitting over the previous week. Each person had a high-resolution MRI scan, which provides a detailed look at the medial temporal lobe, or MTL, a brain region involved in the formation of new memories.

The researchers found that sedentary behavior is a significant predictor of thinning of the MTL and that physical activity, even at high levels, is insufficient to offset the harmful effects of sitting for extended periods.

This study does not prove that too much sitting causes thinner brain structures, but instead that more hours spent sitting are associated with thinner regions, researchers said. In addition, the researchers focused on the hours spent sitting, but did not ask participants if they took breaks during this time.

The researchers next hope to follow a group of people for a longer duration to determine if sitting causes the thinning and what role gender, race, and weight might play in brain health related to sitting.

IMPACT

MTL thinning can be a precursor to cognitive decline and dementia in middle-aged and older adults. Reducing sedentary behavior may be a possible target for interventions designed to improve brain health in people at risk for Alzheimer’s disease, researchers said.

Please check out my Page – Do you know the dangers of too much sitting? for more details on the common practice.

6 Steps to sharpen your brain – Harvard

At the risk of repeating myself I have had three cases of dementia/Alzheimer’s Disease in my family. They occurred on both my mother’s and father’s side, so I am totally paying attention to anything that might help to preserve my cognitive powers. I turned 78 in January. Here is Harvard Healthbeat on the subject.

Everyone has the occasional “senior moment.” Maybe you’ve gone into the kitchen and can’t remember why, or can’t recall a familiar name during a conversation. Memory lapses can occur at any age, but aging alone is generally not a cause of cognitive decline. When significant memory loss occurs among older people, it is generally not due to aging but to organic disorders, brain injury, or neurological illness.

14-1-114

Studies have shown that you can help prevent cognitive decline and reduce the risk of dementia with some basic good health habits:

  • staying physically active
  • getting enough sleep
  • not smoking
  • having good social connections
  • limiting alcohol to one drink a day
  • eating a balanced diet low in saturated and trans fats.

Certain health conditions that can impair cognitive skills include diabetes, high blood pressure, sleep apnea, depression, and hypothyroidism. If you have any of these health issues, you can help protect your memory by following your doctor’s advice carefully.

Memory changes can be frustrating, but the good news is that, thanks to decades of research, you can learn how to get your mind active. There are various strategies we can use to protect and improve memory. Here are several you might try.

1. Keep learning

A higher level of education is associated with better mental functioning in old age. Experts think that advanced education may help keep memory strong by getting a person into the habit of being mentally active. Challenging your brain with mental exercise is believed to activate processes that help maintain individual brain cells and stimulate communication among them. Many people have jobs that keep them mentally active, but pursuing a hobby, learning a new skill, or volunteering for a project at work that involves a skill you don’t usually use can function the same way and help improve memory.

How Do We Lose Memory? A STEP at a Time

Summary: A new study reports increased levels of STEP in the hippocampus is linked to mild cognitive impairment.

 

tumblr_p29g1nRasn1s60oo7o1_400.gif

In mice, rats, monkeys, and people, aging can take its toll on cognitive function. A new study by researchers at Yale and Université de Montréal reveal there is a common denominator to the decline in all of these species — an increase in the level of the molecule striatal-enriched phosphatase, or STEP.

Increased levels of STEP in the hippocampus, a brain structure crucial to the formation of memory, were found in memory-impaired mice and rats, aged rhesus monkeys, and people suffering from mild cognitive impairment, the researchers report March 22 in the journal Current Biology.

High levels of STEP have also been reported in brains of Alzheimer’s patients, the authors note. STEP appears to play a key role in memory consolidation, but too much of it seems to be a bad thing. Young mice and rats with elevated levels of STEP perform more poorly on maze and other memory tests than their peers, and older animals in which STEP is inhibited perform more like young mice.

The scientists hypothesize that as we age we lose ability of to degrade STEP, leading to an unhealthy build up.

“The obvious follow up is to look for STEP inhibitors that will work in people,” said co-corresponding author Paul Lombroso, the Elizabeth Mears and House Jameson Professor in the Child Study Center and professor of neuroscience and of psychiatry.

Mis-remembering vs. forgetting – Seniors Study

As a 78-year-old concerned about his cognitive facilities remaining intact, this Penn State study caught my attention.

buddha-buddhism-statue-religion-46177.jpeg

Older adults often complain about forgetting, but Penn State psychologists suggest that another problem may be mis-remembering.

In a study, the researchers found that as people age, they may be more likely to rely on a type of memory — called schematic memory — that helps them remember the gist of an event, but not necessarily the details. This inability to remember details, though, could lead to difficulty in distinguishing between a memory of something that really happened and something that a person thought happened, but did not — a false memory.

Turmeric compound could boost memory and mood

I have eaten and enjoyed Indian food back in the late 1970’s when I lived in London and didn’t eat meat. Those days are long gone, but I do keep hearing good things about turmeric. Here is a nice rundown from Medical News Today on it.

Not a lover of Indian food? A new study might change your mind. Researchers have found that a compound in turmeric — the spice that gives curry its golden color — could help to improve the mood and memory of older adults.

your-expert-guide-to-turmeric-header-v2-830x467.jpg

Turmeric has been linked to a wealth of health benefits. Last year, for example, Medical News Today reported on a study suggesting that turmeric could help to treat pancreatic cancer, while other research claims the popular spice may help to treat stroke and Alzheimer’s disease. Continue reading

Everyday habits can bolster your memory muscles – Harvard

Regular readers know that I have had several members of my family, or both sides, suffer from dementia in general or Alzheimer’s in particular. So, being a guy in his late 70’s I am particularly sensitive to any kind of cognitive kinks that I may be experiencing. I don’t know if it is my imagination or there are simply more people coming on board the cognitive improvement movement. Herewith, Harvard Healthbeat on tips for strengthening your memory.

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. (my emphasis)

ahr0cdovl3d3dy5saxzlc2npzw5jzs5jb20vaw1hz2vzl2kvmdawlza4ns81ntcvb3jpz2luywwvynjhaw4tbmv1cm9ucy5qcgc.jpeg

Exercise

Physical fitness and mental fitness go together. People who exercise regularly tend to stay mentally sharp into their 70s, 80s, and beyond. Although the precise “dose” of exercise isn’t known, research suggests that the exercise should be moderate to vigorous and regular. Examples of moderate exercise include brisk walking, stationary bicycling, water aerobics, and competitive table tennis. Vigorous activities include jogging, high-impact aerobic dancing, square dancing, and tennis.

Exercise helps memory in several ways. It reduces the risk of developing several potentially memory-robbing conditions like high blood pressure, diabetes, and stroke. Exercise is good for the lungs, and people who have good lung function send more oxygen to their brains. There is some evidence that exercise helps build new connections between brain cells and improves communication between them. Finally, exercise has been linked to increased production of neurotrophins, substances that nourish brain cells and help protect them against damage from stroke and other injuries.

 

Here are some ways to build physical activity into your daily routine:

Walk instead of driving when possible.

Set aside time each day for exercise. For extra motivation, ask your spouse or a friend to join you.

Use the stairs instead of the elevator.

6 Ways to a better memory – Infographic

When I was in the working world, my memory was constantly being tested. Now that I am retired my memory concerns have morphed. Being a senior citizen, I feel more aware of and am more concerned about my memory for non-professional, but very personal, reasons. I have suffered from senior moments ever since I was in my fifties. I hope that is all they are and not a prelude to any serious cognitive situations. I thought this little infographic on building up your memory might be useful to you no matter what your age is.

A salad a day may keep memory problems away – Study

If an apple a day keeps the doctor away, perhaps we finally have a follow up for seniors worried about slippage in cognition.

Eating about one serving per day of green, leafy vegetables may be linked to a slower rate of brain aging, according to a study published in the December 20, 2017, online issue of Neurology®, the medical journal of the American Academy of Neurology.

2-brain

The study found that people who ate at least one serving of green, leafy vegetables a day had a slower rate of decline on tests of memory and thinking skills than people who never or rarely ate these vegetables. The difference between the two groups was the equivalent of being 11 years younger in age, according to study author Martha Clare Morris, ScD, of Rush University Medical Center in Chicago. (my emphasis)

“Adding a daily serving of green, leafy vegetables to your diet may be a simple way to foster your brain health,” said Morris. “Projections show sharp increases in the percentage of people with dementia as the oldest age groups continue to grow in number, so effective strategies to prevent dementia are critical.” Continue reading

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.

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.

Exercise can boost your memory and thinking skills

Eat less; move more; live longer. That is the mantra of this blog. moving more keeps the organic machines we know as our bodies in tip top shape. As it turns out exercise is also good for the old cabeza.

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

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.

Exercise boosts your memory and thinking skills both directly and indirectly. It acts directly on the body by stimulating physiological changes such as reductions in insulin resistance and inflammation, along with encouraging production of growth factors — chemicals that affect the growth of new blood vessels in the brain, and even the abundance, survival, and overall health of new brain cells.

dscf6189

It also acts directly on the brain itself. Many studies have suggested that the parts of the brain that control thinking and memory are larger in volume in people who exercise than in people who don’t. “Even more exciting is the finding that engaging in a program of regular exercise of moderate intensity over six months or a year is associated with an increase in the volume of selected brain regions,” says Dr. McGinnis.

5 Ways to keep your memory sharp – Harvard

Regular readers know that I am a senior citizen; will be 77 in January. So, I have a lot of senior friends. We have all experienced ‘senior moments’ when we find our memory becoming slightly elusive. Because my family has had Alzheimer’s and other forms of dementia I am particularly sensitive to any brain stuff. So I was impressed with the suggestions that Harvard brought forward regarding enhancing our memory.

The way you live, what you eat and drink, and how you treat your body can affect your memory just as much as your physical health and well-being. Here are five things you can do every day to keep both your mind and body sharp.

1. Manage your stress. The constant drumbeat of daily stresses such as deadline pressures or petty arguments can certainly distract you and affect your ability to focus and recall. But the bigger problem is an ongoing sense of anxiety — that can lead to memory impairment. If you don’t have a strategy in place for managing your stress, protecting your memory is one reason to get one. Deep breathing, meditation, yoga, and a “mindful” approach to living can all help.

I have posted a number of times on stress. You can find them by searching s t r e s s in the box at the right. If you want one excellent example check out: Super tools for handling stress.

9 Reasons To Eat Honey Daily

I was lucky enough to be exposed to some of these facts about honey years ago. Been using it ever since.

Honey

Tony

Our Better Health

 The possible health benefits of honey have been documented in early Greek, Roman, Vedic, and Islamic texts and healing qualities of honey were referred to by philosophers and scientists all the way back to ancient times, such as Aristotle (384-322 BC) and Aristoxenus (320 BC). – Joseph Nordqvist, Medical News Daily
For something that tastes so good, honey isn’t consumed all that often. Besides being delicious, honey is also densely packed with valuable nutrition, such as nutrients. Honey is also quite healthy: a tablespoon of raw, unadulterated honey contains 64 calories, and is free from cholesterol, fat, and sodium.
The ideal nutritional composition of honey almost assuredly helps give the natural sweeter its health-promoting properties. Here, we’re going to discuss nine such health benefits of this sweet nectar.

“Super-aging” seniors retain healthy memory abilities – Study

Because I have both Alzheimer’s and dementia in my family, I am extremely sensitive to this kind of news about the aging brain and memory. Check out my Page – Important facts about your brain (and exercise benefits) to read further.

Some loss of memory is often considered an inevitable part of aging, but new research reveals how some people appear to escape that fate. A study by Massachusetts General Hospital (MGH) investigators examines a remarkable group of older adults whose memory performance is equivalent to that of younger individuals and finds that certain key areas of their brains resemble those of young people.

muscle_brain.jpg

The study published in The Journal of Neuroscience is the first step in a research program aimed at understanding how some older adults retain youthful thinking abilities and the brain circuits that support those abilities. The program is led by Bradford Dickerson, MD, director of the Frontotemporal Disorders Unit in the MGH Department of Neurology and Lisa Feldman Barrett, PhD, MGH Department of Psychiatry, who are co-senior authors of the new study.

080816 Protect your memory by staying at a healthy weight

New research recently published in the Journal of the American Geriatrics Society found a link between weight and memory loss in older women. An analysis of data gathered from 8,745 women, aged 65-79, showed no signs of dementia at the beginning of this study. Things changed.

Throughout the study, periodic body mass index (BMI) measurements were taken on the participants.

The researchers found that for every increase in the BMI unit, memory loss also increased when measured from the memory test. This is not unexpected.

Clearly, from all the scientific studies conducted over the years, there is a direct link between excess body fat and heart disease. The fact is that for every risk for cardiovascular disease there is also a risk for Alzheimer’s disease. Therefore, the findings were not inconsistent with other data gathered relating to weight gain, cardiovascular…
