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 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.

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

Memory loss reversed in early Alzheimer’s – Study

Researchers have successfully reversed memory loss in a small number of people with early-stage Alzheimer’s disease using a comprehensive treatment program, which involves a combination of lifestyle changes, brain stimulation, and medication.

Researchers suggest the MEND program is highly effective for reversing memory loss.

2-brain

Memory improvements as a result of the treatment program have so far been sustained for 2 years, the researchers report, and some patients have even been able to return to work as a result.

Study co-author Dr. Dale Bredesen, of the Buck Institute on Research and Aging in Novato, CA, and colleagues recently published their findings in the journal Aging.

While the study only involved 10 patients, the researchers believe their findings may open the door to an effective therapy for cognitive decline.

“The magnitude of improvement in these 10 patients is unprecedented, providing additional objective evidence that this programmatic approach to cognitive decline is highly effective,” says Dr. Bredesen.

There are currently around 5.4 million people in the United States living with Alzheimer’s disease. Continue reading

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.

Does Eating Fish Help Memory?

A diet lacking in omega-3 fatty acids, nutrients commonly found in fish, may cause your brain to age faster and lose some of its memory and thinking abilities, according to a study published in the print issue of Neurology®, the medical journal of the American Academy of Neurology.

“People with lower blood levels of omega-3 fatty acids had lower brain volumes that were equivalent to about two years of structural brain aging,” said study author Zaldy S. Tan, MD, MPH, of the Easton Center for Alzheimer’s Disease Research and the Division of Geriatrics, University of California at Los Angeles.

For the study, 1,575 people with an average age of 67 and free of dementia underwent MRI brain scans. They were also given tests that measured mental function, body mass and the omega-3 fatty acid levels in their red blood cells.

SelfNutrition Data lists the following foods as high in Omega-3 fatty acids: In order of importance: based on 200 calorie serving:
Flaxseed oil is the highest with 12,059 mg.
Flax seeds have 8,543 mg.
Fish oil, salmon contains 7828 mg.
Chia seeds yields 7164 mg.
Agutuk, fish with shortening has 6851 mg.

Physical Activity Improves Memory in Seniors – Boston University Study

There are few things more gratifying than seeing some authoritative source come out with findings that confirm something that I have been saying for some time. Just two days ago I posted Does Prevagen Really Improve Memory?

This was my attempt to protect innocent senior citizens who might have experienced senior moments and feared they had to run to the drugstore and buy this drug to protect their aging brains.

Now comes this press release from Boston University:

“Could staying physically active improve quality of life by delaying cognitive decline and prolonging an independent lifestyle? A new study has found that older adults who take more steps either by walking or jogging perform better on memory tasks than those who are more sedentary.

“The study examines the relationship between physical activity, memory and cognition in young and old adults. It appears online in the Journal of the International Neuropsychological Society.

“The study included 29 young adults (ages 18-31) and 31 older adults (ages 55-82) who wore a small device called an ActiGraph, which recorded information including how many steps each took, how vigorous the steps were and how much time it involved.

Participants also completed neuropsychological testing to assess their memory, planning and problem-solving abilities. In addition to standardized neuropsychological tasks of executive function (planning and organization abilities) and long-term memory, participants engaged in a laboratory task in which they had to learn face-name associations.

“The researchers found that older adults who took more steps per day had better memory performance. The association between the number of steps taken was strongest with a task that required recalling which name went with a person’s face—the same type of everyday task that older adults often have difficulty with. In young adults, the number of steps taken was not associated with memory performance.

“According to the researchers these findings demonstrate that the effects of physical activity extend to long-term memory—the same type of memory that is negatively impacted by aging and neurodegenerative dementias such as Alzheimer’s disease. ‘’Our findings that physical activity is positively associated with memory is appealing for a variety of reasons. Everyone knows that physical activity is a critical component to ward off obesity and cardiovascular-related disease. Knowing that a lack of physical activity may negatively impact one’s memory abilities will be an additional piece of information to motivate folks to stay more active,” explained corresponding author Scott Hayes, PhD, assistant professor of psychiatry at Boston University School of Medicine and the Associate Director of the Neuroimaging Research for Veterans Center at the VA Boston Healthcare System.

Dietary Flavanols Reverse Age-Related Memory Decline

“When we imaged our research subjects’ brains, we found noticeable improvements in the function of the dentate gyrus in those who consumed the high-cocoa-flavanol drink,” says lead author Adam M. Brickman, PhD, an associate professor of neuropsychology at the Taub Institute.

Cooking with Kathy Man

Dietary cocoa flavanols—naturally occurring bioactives found in cocoa—reversed age-related memory decline in healthy older adults, according to a study led by Columbia University Medical Center (CUMC) scientists. The study, published in the advance online issue of Nature Neuroscience, provides the first direct evidence that one component of age-related memory decline in humans is caused by changes in a specific region of the brain and that this form of memory decline can be improved by a dietary intervention.

As people age, they typically show some decline in cognitive abilities, including learning and remembering such things as the names of new acquaintances or where one parked the car or placed one’s keys. This normal age-related memory decline starts in early adulthood but usually doesn’t have any noticeable impact on quality of life until people reach their fifties or sixties. Age-related memory decline is different from the often-devastating memory impairment that occurs with…

A Memory Aid for Seniors: Laughter

“It’s simple, the less stress you have, the better your memory,” one of the study’s authors, Lee Berk, said in a Federation of American Societies for Experimental Biology news release. “Humor reduces detrimental stress hormones like cortisol that decreases memory [brain cells], lowers your blood pressure and increases blood flow and your mood state. The act of laughter — or simply enjoying some humor — increases the release of endorphins and dopamine in the brain, which provides a sense of pleasure and reward.

Cooking with Kathy Man

Humor and laughter may help combat memory loss in the elderly, a new study suggests.

Previous research has found that the stress hormone cortisol can harm memory and learning ability in older adults. This new study examined whether mirth might reduce the damage caused by cortisol.

Researchers showed a 20-minute humorous video to a group of healthy seniors and a group of seniors with diabetes. These groups were compared with a group of seniors who didn’t see the video.

The two groups that watched the funny video showed significant decreases in cortisol levels and greater improvements on memory tests, compared to the group that didn’t see the video. The diabetes group showed the largest decrease in cortisol levels, while the healthy group had the greatest improvement on memory tests.

The study was to be presented Sunday at the Experimental Biology meeting in San Diego. Research presented at meetings should be…

Green tea is said to have many putative positive effects on health. Now, researchers at the University of Basel are reporting first evidence that green tea extract enhances the cognitive functions, in particular the working memory. The Swiss findings suggest promising clinical implications for the treatment of cognitive impairments in psychiatric disorders such as dementia. The academic journal Psychopharmacology has published their results.

In the past the main ingredients of green tea have been thoroughly studied in cancer research. Recently, scientists have also been inquiring into the beverage’s positive impact on the human brain. Different studies were able to link green tea to beneficial effects on the cognitive performance. However, the neural mechanisms underlying this cognitive enhancing effect of green tea remained unknown.
