Meditation and Music May Alter Blood Markers of Cellular Aging and Alzheimer’s Disease in Adults with Early Memory Loss

A research team led by Dr. Kim Innes, a professor in the West Virginia University School of Public Health, has found that a simple meditation or music listening program may alter certain biomarkers of cellular aging and Alzheimer’s Disease in older adults who are experiencing memory loss. Study findings, reported in the Journal of Alzheimer’s Disease, also suggest these changes may be directly related to improvements in memory and cognition, sleep, mood, and quality of life.

Sixty older adults with subjective cognitive decline (SCD), a condition that may represent a preclinical stage of Alzheimer’s disease, participated in the randomized, clinical trial. While SCD has been linked to increased risk for dementia and associated with certain neuropathological changes implicated in Alzheimer’s disease development, including elevated brain levels of beta amyloid, this preclinical period may also provide a critical window for therapeutic intervention.

In this trial, each participant was randomly assigned to either a beginner meditation (Kirtan Kriya) or music listening program and asked to practice 12 minutes/day for 12 weeks. At baseline and 3 months, blood samples were collected. Two markers of cellular aging were measured: telomere length and telomerase activity. (Telomeres serve as protective caps on chromosomes; telomerase is an enzyme responsible for maintaining telomere length). Blood levels of specific beta-amyloid peptides commonly linked to Alzheimer’s Disease were also assessed. In addition, memory and cognitive function, stress, sleep, mood, and quality of life were measured. All participants were followed for a total of 6 months. Continue reading →

Alzheimer’s Genetically Linked to Cardiovascular Disease – Study

Studying DNA from more than 1.5 million people, an international team of researchers — led by Washington University School of Medicine in St. Louis and the University of California, San Francisco — has identified points of DNA that increase the risk of cardiovascular disease and also heighten the risk for Alzheimer’s disease, according to an article in Neuroscience News.

neuroplasticity-aging-neuroscinecneews-public

Scientists have long been aware of connections between variations of the APOE gene, which is involved in cholesterol and lipid metabolism, and Alzheimer’s disease. That gene is known to double the risk for Alzheimer’s disease in some patients and increase risk by up to 12 times in others. But in the new study, the researchers identified other DNA points that also appear to be involved both in cardiovascular disease risk and the risk for Alzheimer’s. Continue reading →

Alzheimer’s symptoms may be predicted during eye exam

With three cases of Alzheimer’s Disease or dementia in my family I have serious interest in all variations of cognitive impairment. Hence, this latest work from Washington University School of Medicine.

It may be possible in the future to screen patients for Alzheimer’s disease using an eye exam.

brain

Using technology similar to what is found in many eye doctors’ offices, researchers at Washington University School of Medicine in St. Louis have detected evidence suggesting Alzheimer’s in older patients who had no symptoms of the disease.

Their study, involving 30 patients, is published Aug. 23 in the journal JAMA Ophthalmology. Continue reading →

The difference between Alzheimer’s and dementia – Mayo Clinic

I have talked a lot about Alzheimer’s Disease and dementia over the past eight years, so when I ran across this explanation from the Mayo Clinic, I thought I would share it with  you.

These terms are often used interchangeably, but they actually have very different meanings. Dementia is not a specific disease. It’s an overall term, sometimes referred to as an umbrella term, which describes a wide range of symptoms. These symptoms impact a person’s ability to perform everyday activities independently. Common symptoms include:

A decline in memory
Changes in thinking skills
Poor judgment and reasoning skills
Decreased focus and attention
Changes in language and communication skills

screen-shot-2016-09-17-at-1-39-03-pm1.png

Alzheimer’s disease is one type of dementia, but it’s not the only one. There are many different types and causes of dementia, including:

Lewy body dementia
Frontotemporal dementia
Vascular dementia
Parkinson’s disease dementia
Creutzfeldt-Jakob disease
Huntington’s disease
Mixed dementia

Alzheimer’s disease, however, is the most well-known and common form of dementia but not everyone with dementia has Alzheimer’s disease.

Obesity Plus Aging Linked to Alzheimer’s Markers in the Brain

A new study reports high sugar and fat based diets that lead to obesity, coupled with the normal aging process, may increase the risk of Alzheimer’s disease. By my reckoning that means the older we get the more we need to pay attention to what we are eating and the amount we are exercising. Eat less; move more; live longer. For heaven’s sake, don’t wait till you are a senior to get on the exercise and good eating regime. Clearly, the earlier you start, the better of you are.

A new study suggests that when a high-fat, high-sugar diet that leads to obesity is paired with normal aging, it may contribute to the development of Alzheimer’s disease. In addition, researchers discovered that certain areas of the brain respond differently to risk factors associated with Alzheimer’s. The study is published in Physiological Reports.

Alzheimer’s disease, the most common form of dementia, is a progressive brain disorder that leads to loss of cognitive skills and memory and causes significant changes in behavior. Aging is a significant risk factor for Alzheimer’s. Previous studies suggest that diet-related obesity is also associated with development of the disease. Continue reading →

Researchers Reverse Cognitive Impairment in Mice with Dementia

If you have been reading this blog for a while you are aware that I have a particular focus on the brain afflictions – dementia and its move common manifestation, Alzheimer’s. Three members on both sides of my family suffered from a form of dementia. While there is no cure or preventative for Alzheimer’s, it seems that exercise is our best chance of possessing a functioning brain in our old age. Hence, my focus on movement of every kind. Now, it seems that we may be getting a new arrow in our quiver to fight mental illness.

Researchers report tau pathology can be reversed in Alzheimer’s patients with the help of a drug. Their study reveals reversing tau pathology in mouse models of dementia resulted in a reversal of cognitive deficits in spatial learning.

tau-dementia-cognition-neurosciencenews-public

Compared with untreated animals, tau mice that had received zileuton performed significantly better on the tests. Their superior performance suggested a successful reversal of memory deficiency. NeuroscienceNews.com image is in the public domain.

Reversing memory deficits and impairments in spatial learning is a major goal in the field of dementia research. A lack of knowledge about cellular pathways critical to the development of dementia, however, has stood in the way of significant clinical advance. But now, researchers at the Lewis Katz School of Medicine at Temple University (LKSOM) are breaking through that barrier. They show, for the first time in an animal model, that tau pathology – the second-most important lesion in the brain in patients with Alzheimer’s disease – can be reversed by a drug.

 “We show that we can intervene after disease is established and pharmacologically rescue mice that have tau-induced memory deficits,” explained senior investigator Domenico Praticò, MD, Scott Richards North Star Foundation Chair for Alzheimer’s Research, Professor in the Departments of Pharmacology and Microbiology, and Director of the Alzheimer’s Center at Temple at LKSOM. The study, published online in the journal Molecular Neurobiology, raises new hope for human patients affected by dementia. Continue reading →

Alzheimer’s Disease Redefined

Researchers have published a new study framework that defines Alzheimer’s disease by brain changes, not symptoms.

“NIA-AA Research Framework: Towards a Biological Definition of Alzheimer’s Disease” was published in the April 2018 issue of Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association. First author Clifford R. Jack, Jr., M.D., of Mayo Clinic Rochester, MN and colleagues propose shifting the definition of Alzheimer’s disease in living people – for use in research – from the current one, based on cognitive changes and behavioral symptoms with biomarker confirmation, to a strictly biological construct. This represents a major evolution in how we think about Alzheimer’s.

alzheimers-redefined-neurosciencenews-public.jpg

In 2011, the Alzheimer’s Association (AA) and the National Institute on Aging (NIA) at the U.S. National Institutes of Health convened experts to update the diagnostic guidelines for Alzheimer’s disease. NeuroscienceNews.com image is in the public domain.

Understanding and effectively treating Alzheimer’s disease and other dementias may be the most difficult challenge for the medical/scientific community this century. The field has experienced monumental challenges developing new and effective drug therapies, not the least of which was the discovery that – until recently – clinical trials were conducted where up to 30% of participants did not have the Alzheimer’s disease-related brain change targeted by the experimental drug.

Alzheimer’s in the family – What next? – Harvard

Dementia affects the person diagnosed but also raises fears for siblings and children. Here are the facts.

I have three cases of Alzheimer’s/dementia on both sides of my family, including mother, aunt and grandfather. So, I am extremely sensitive to any information on the subject of cognition and aging. One of the aspects of Alzheimer’s that few people consider, until a loved one becomes afflicted, is that the relatives and people who care about the person suffer greatly as they see a person they loved deteriorate mentally and physically before their eyes. It also raises the specter of – what about me? Will I get it, too?

ae61fa971d0de44729ca768dde1a72d0.gif

Here is a good no nonsense discussion from Harvard Men’s Health Watch.

Alzheimer’s disease represents a personal health crisis, but it’s also a family concern. What does it mean for your children or siblings if you are diagnosed with Alzheimer’s? What does it mean for you if a close relative develops the condition?

“People think that if their dad or aunt or uncle had Alzheimer’s disease, they are doomed. But, no, that’s not true,” says Dr. Gad Marshall, assistant professor of neurology at Harvard Medical School. “Even though family history adds to the overall risk, age still usually trumps it quite a bit. It means your risk is higher, but it’s not that much higher, if you consider the absolute numbers.”

Family history by the numbers

Studies of family history say that if you have a close relative who has been diagnosed with Alzheimer’s disease—the most common form of dementia in older adults—your risk increases by about 30%. This is a relative risk increase, meaning a 30% hike in your existing risk. Continue reading →

Aerobic exercise may ease some Alzheimer’s symptoms

Regular readers how focused I am on the connection between exercise and the brain. I lost three family members to Alzheimer’s Disease or another form of dementia. And, I just turned 78 two weeks ago. So, I was most interested in this report on the benefits of aerobic exercise on Alzheimer’s symptoms. When you finish reading, please check out my Page – Important facts about  your brain (and exercise benefits.)

Alzheimer’s Disease is a brain disorder that destroys memory and thinking skills over time. It is the most common form of dementia in older adults. There is presently no cure for the condition, though treatment options are available. Today, some 5.3 million Americans live with Alzheimer’s Disease, and it is the sixth leading cause of death in the United States. The number of older adults who will develop AD is expected to more than triple by 2050.

Geriatrics experts have suggested that exercising can improve brain health in older adults. The World Health Organization (WHO) has recommendations for how much older adults should exercise. They suggest that older adults perform 150 minutes a week of moderate exercise (such as brisk walking), 75 minutes a week of vigorous aerobic training, or a combination of the two types. The WHO also recommends older adults perform muscle-strengthening exercises on at least two or more days a week. Continue reading →

Massaging Brain Cells to Fight Alzheimer’s

I have written repeatedly about physical exercise benefiting the brain. It seems that now a new study has found a way to actually stimulate the brain cells which may benefit individuals suffering from Alzheimer’s Disease.

Some researchers at Montana State University have a light touch when it comes to unraveling the mysteries of the brain and exploring new ways to treat diseases like Alzheimer’s.

Lack of Sleep Boosts Levels of Alzheimer’s Protein – Study

I wrote about the dangers of sleep deprivation earlier this week. Here is the opening paragraph of that post: Regular readers know that I am an old man and very highly value a good night’s sleep. That is not the way I felt 20 years ago when I was in the working world. In those days I felt strongly that sleep was an intrusion on my life and activities and resented having to do it. I got a little wiser as the years went by. Please check out my Page – How important is a good night’s sleep? for significantly more details on this very important aspect of living a long healthy life.

830c88f78a26b084002c883eb628074e

Have you resolved to take better care of yourself in the new year? Here’s a relatively painless way to do it: Catch a few more zzz’s every night. A third of American adults don’t get enough sleep, according to the Centers for Disease Control and Prevention..

Chronic poor sleep has been linked to cognitive decline, and a new study from Washington University School of Medicine in St. Louis explains why: As a wakeful brain churns away through the night, it produces more of the Alzheimer’s protein amyloid beta than its waste-disposal system can handle. Levels of the protein rise, potentially setting off a sequence of changes to the brain that can end with dementia.

“This study is the clearest demonstration in humans that sleep disruption leads to an increased risk of Alzheimer’s disease through an amyloid beta mechanism,” said senior author Randall Bateman, MD, the Charles F. and Joanne Knight Distinguished Professor of Neurology. “The study showed that it was due to overproduction of amyloid beta during sleep deprivation.” Continue reading →

Can you get Alzheimer’s when you are young?

I used to attend regularly a program at Northwestern Memorial Hospital called ‘Healthy Transions.’ It was for folks over 55 years old and dealt with the situations they would encounter as they aged. The most popular talks by far were the ones on MCI – mild cognitive impairment, and Alzheimer’s Disease. It’s not surprising that as we age we get serious concerns about our brains functioning fully.

8a247afb6a437b3f2aca2337f66d88a9.gif

Here is what Sharecare had to say on the subject: We rightly associate Alzheimer’s disease with an older population. Most people who develop this progressive brain disorder are age 65 and older. Currently some 5.5 million Americans—two-thirds of them women—live with the disease. But hidden within that estimate, a smaller number—approximately 200,000 adults—develop the condition under the age of 65. When this happens, it’s called younger-onset, or early-onset Alzheimer’s. “Alzheimer’s is just one type of dementia, and given the frequency of early-onset it’s somewhat uncommon,” says H. Rai Kakkar, MD, a neurologist at Presbyterian/St. Luke’s Medical Centerin Denver, Colorado.

How is early-onset different?
Early-onset Alzheimer’s disease (EOAD) is the same as Alzheimer’s disease in terms of progressive deterioration of cognitive function, but there are differences in causes. Some cases are the result of familial Alzheimer’s disease (FAD), caused by an inherited change in one of several specific genes. Continue reading →

Winter is coming. Are you ready for it?

I would like to add a personal word here. When I first started taking care of my aunt with Alzheimer’s some years ago I was concerned about her handling winter. We had always been close and I remember that winter’s short and dark days got her down. The doctor had told me that she would be able to live at home if she didn’t become aggressive. I had no idea how to keep her mood up but I stumbled upon an article about these full spectrum lights that mimic the sun’s rays.

So, I thought I would get her a couple of these lamps to fool her body and brain away from dark thoughts and moods. Long story short: it worked. She was able to live out her life in her own house. By the way, this was the house she moved into when she married my uncle more than 60 years earlier.

Our Better Health

Well with the forecast in mind, snow, wind, and all the things associated with it, I have to ask: Are you ready for winter?

The ten foot snow banks, the blizzards, the -38 C wind chills, the bad roads and everything else that I’d rather not even think about right now?

Hold on a second.

You might have assumed I was talking about the physical requirements to get through yet another Winnipeg winter, but I wasn’t. We all go through it every year right? Winter clothes are in good shape? Check. The furnace is in good working order? Check. Got the winter tires on? Check.

Sure all those things are necessary to get by in the six month Manitoba deep freeze, but what about mental preparation?

I never used to think about that very much because you just dealt with it, you handled it. You knew what to expect and…

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 →
