Source: What is the key to healthy aging? New gene study sheds light – Medical News Today
A new study may bring us closer to unlocking the secret to healthy aging, after uncovering an array of genetic variants among healthy, elderly individuals that may protect against Alzheimer’s and heart disease.
Researchers have uncovered some of the secrets of healthy aging with their new gene study.
The findings come from the ongoing “Wellderly” study, in which researchers have so far applied whole genome sequencing to the DNA of more than 1,400 healthy individuals from the US aged 80-105 years.
Launched in 2007, the study aims to pinpoint certain genetic variants that may contribute to lifelong health.
“This study is exciting because it is the first large one using genetic sequencing to focus on health,” says Michael Snyder, PhD, chairman of the Department of Genetics at Stanford University in California, who was not involved with the research. Continue reading
Source: What is a Cardiac Risk Calculator? What are the Best Heart Health Predictors? – Medical News Today
There are three considerations about cardiac risk calculators. The first is that, whichever exact approach is taken, the idea is the same – to take measurements of cardiovascular health and analyze them for guidance on future potential heart problems and their prevention.
The second is that while the factors are common to whichever calculator is used, it is often one recommended by a doctor, validated for as much scientific accuracy as possible.
Health care professionals take the cardiac risk measurements and can help understand results and explain what to do about them to help avoid heart attack and stroke.
The third is that a prediction of future chances of heart problems is just that – a prediction. It is not supposed to be as scary or as certain as it might sound.
Risks can be put into perspective, and they would not be calculated unless there was something worthwhile that could be done to reduce them.
For some people, the predicted cardiac risk is so low that there would be no need to worry about further screening.
The reason why medicine has developed cardiovascular risk calculators is for the major effort to take on “the common risk factors fueling the epidemic of cardiovascular disease” Continue reading
Source: Intensive exercise may keep the aging mind sharp – LA Times
Older Americans who engage in strenuous exercise are more mentally nimble, have better memory function and process information more speedily than do their more sedentary peers, new research suggests. And as they continued to age, participants who were very physically active at the start of a five-year study lost less ground cognitively than did couch potatoes, according to the study.
The latest research, published Wednesday in the journal Neurology, is the most recent study to underscore the importance of moderate to intensive exercise in healthy aging. In addition to keeping diabetes, heart disease and osteoporosis at bay or in check, a welter of studies suggests a good workout is powerful medicine for the aging brain, preventing and treating depression and shoring up cognitive function.

Source: Being socially active may boost late-life satisfaction and ease decline – Medical News Today
Well-being at the end of life often declines steeply, with significant differences among individuals that are poorly understood, say researchers who show that staying active socially – despite health challenges – appears to lessen and delay the onset of late-life decline.
The study shows that being socially active and having social goals were linked to higher well-being or life-satisfaction late in life.
The study – published in Psychology and Aging – was led by Dr. Denis Gerstorf, of Humboldt University in Berlin. His colleagues include members of Arizona State University and other research centers in the US and Germany. Dr. Gerstorf notes:
“Our results indicate that living a socially active life and prioritizing social goals are associated with higher late-life satisfaction and less severe declines toward the end of life.” Continue reading
Source: Survey Reveals Beliefs, Behaviors on Alzheimer’s « Inside Health News
People recognize the seriousness of Alzheimer’s disease, but they aren’t taking steps to learn about their personal chances of getting the disease or to prepare for it financially, according to a new survey.
The WebMD and Shriver Report Snapshot: “Insight Into Alzheimer’s Attitudes and Behaviors,” asked more than 4,200 WebMD readers their beliefs and experiences regarding the disease.
“It’s incredibly tough to think about losing your mind or watching a loved one struggle with Alzheimer’s,” says Michael Smith, MD, WebMD’s chief medical editor. “There is great concern about the impact of this disease, but denial, fear or other unknown factors seem to be preventing us from taking the necessary steps to prepare.”
Still, many people say they are taking actions to stay healthy that might benefit their brains as they age.
An estimated 1 in 9 people over 65 (11%) have Alzheimer’s, according to the Alzheimer’s Association. As the population ages, however, those numbers are expected to nearly triple by 2050. Continue reading
Source: Social Groups May Lengthen Retirees’ Lives
Staying socially active by joining book clubs or church groups may add years to your life after retirement, a new study suggests.
The more groups a person belongs to in early retirement, the lower their risk of premature death, Australian researchers found. The chance of dying within six years of stopping work was 2 percent for people who were members of two social groups before retiring and stayed in both. If they left one group, their risk of death increased to 5 percent, and it rose to 12 percent if they left both groups.
“The sense of belonging that social group connections provide helps people sustain a meaningful and healthy life,” said lead researcher Niklas Steffens, a lecturer at the University of Queensland in Brisbane, Australia. Continue reading

Testosterone treatment in the form of a topical gel boosts sexual function, mood and walking ability for older men with low levels of the hormone. This is the conclusion of new research published in The New England Journal of Medicine.
Researchers found that testosterone therapy improved the sexual function, mood and walking ability of older men.
The study – co-led by Dr. Ronald Swerdloff, a researcher at the Los Angeles Biomedical Research Institute (LA Biomed) in California – reveals the results of the first three trials that form part of the Testosterone Trials (TTrials).
The TTrials are a set of seven double-blind, placebo-controlled studies that aim to determine the safety and effectiveness of testosterone treatment among men aged 65 and older.
The initial results suggest that over a 1-year period, daily application of a testosterone gel boosted blood testosterone levels of older men to levels normally seen in younger men, which improved their sexual function, mood and walking ability. Continue reading

Source: Leslie Beck: How to maintain a healthy diet on a tight food budget – The Globe and Mail
If you’re dedicated to eating healthily, rising food costs can make meal planning and grocery shopping a challenge. Research suggests that when our food budget is stretched, fresh fruits and vegetables, meat and fish appear less often in our shopping cart – and with that go many essential nutrients, including vitamins A, C and K, folate, B12, potassium, iron and omega-3 fatty acids.
For those on a fixed income, such as seniors, it can be tricky to find affordable, nutritious food. Many key nutrients needed to maintain health as we get older, in particular brain health, are found in increasingly pricey foods, the very foods that can get squeezed out of a tight food budget.
A weak dollar, climate change and consumer trends are expected to continue to push up the price of our grocery bill this year. The University of Guelph’s Food Institute anticipates our food bill will rise as much as 4 per cent in 2016, costing the average Canadian household an additional $345. Continue reading

A study by Simon Fraser University researchers suggests that the number of children born to a woman influences the rate at which her body ages.
The study led by health sciences professor Pablo Nepomnaschy and postdoctoral researcher Cindy Barha found that women who give birth to more surviving children exhibited longer telomeres. Telomeres are the protective tips found at the end of each DNA strand and are indicative of cellular aging. Longer telomeres are integral to cell replication and are associated with longevity.

August last year saw the passing of much-loved actor and comedian Robin Williams. At the time, friends and colleagues of the star claimed that depression led him to take his own life. But earlier this week, his widow Susan said this was not the case; his death was the result of a debilitating brain disease known as Lewy body dementia.
It was recently revealed that late actor Robin Williams had Lewy body dementia, which his widow believes was responsible for his death.
“Lewy body dementia is what killed Robin,” Susan told ABC News. “It’s what took his life and that’s what I spent the last year trying to get to the bottom of, what took my husband’s life.”
Susan explained that it was during Williams’ autopsy that a coroner found signs of Lewy body dementia (LBD), and doctors who analyzed the autopsy report told her it was one of the most severe cases they had ever seen. Continue reading

Structural deterioration of the brain associated with old age can be eased by long-term aerobic exercise starting in mid-life, according to research published in PLOS Biology.
Exercise from middle age can help prevent dementia later in life.
Frailty and cognitive decline tend to accompany aging, and exercise is known to combat them. How this works is not completely understood, but the development of dementias such as Alzheimer’s disease has been linked with physical inactivity.
The risk of dementia increases with age. Age-related cognitive deficits result partly from changes in neuronal function, but also correlate with deficiencies in the blood supply to the brain and with low-level inflammation. Continue reading

My dad, Bernie, was a collector. Bernie passionately lectured me on the many uses of paper grocery bags as he carefully grouped them into stacks of 10, tied them with twine and filed them in the furnace room. He collected pens as if one day there might be a global ink shortage. The pens were grouped meticulously and filed in a special drawer.
After my mother died, Bernie lived by himself. I visited him regularly and felt that, at 85 years old, he was doing well. I did notice a few changes, but I attributed them to age. His love of collecting paper bags and pens strengthened, but the neat and tidy nature of his collection started to slip, and the house became cluttered. Continue reading

Source: Long-Term Study Finds The Hearts Of Women And Men Age Differently | IFLScience
The health of your heart is impacted by a number of different factors, from smoking to diabetes, meaning that depending on lifestyle choices, people’s hearts age at different rates. A new study has found out, however, that its aging rate also depends on your sex.
By following close to 3,000 patients over a period of 10 years, the researchers were able to track how patients’ hearts changed during this period using MRI scans. This tracking over time was important, because previous studies looking into the differences in aging of hearts had simply compared those of young and old people at a single point in time, which couldn’t therefore account for differences in lifestyles or medical history. Checking up on the same individuals periodically, they found that there were surprising differences between the aging of hearts in both men and women. Continue reading
