Should we screen everyone for dementia?
March 27, 2014 By Leave a Comment
More than 5 million adults in the U.S. suffer from Alzheimer’s disease, and even more suffer from other dementias that result in memory loss and speech difficulties, and interfere with thinking and plans skills.
Most of the time, dementia is diagnosed when a caregiver such as a doctor notices symptoms in a patient, or when a caregiver suspects something is wrong. Experts believe that leaves a vast majority of dementia cases in the primary setting undiagnosed. [Read more…]

Healthy mouths and teeth are an important component in our overall health that enables us to eat healthy foods and keep bacteria at bay. Now there’s new information that older adults – especially those in long-term care facilities – are not getting the oral health care they need. [Read more…]
Does diet impact your brain?
October 28, 2013 By 1 Comment
We all know that the food we eat has an effect on health. There is plenty of evidence that the risks of developing health conditions, like heart disease and diabetes, are directly related to our diets. Now a new systematic review finds evidence that diet effects brain function as well.

The facts on Social Security
October 1, 2012 By Leave a Comment
More than 75 years ago, the U.S. government created Social Security, the federal insurance program that provides benefits to individuals and their families who can no longer work because of disability, retirement or death. The program is complex, and its details are often debated among politicians.
Earlier this year, the Economic Policy Institute and the National Academy of Social Insurance published a guide that explains the facts about the Social Security program to young people. The document includes detailed, evidence-based explanations of Social Security’s history, beneficiaries, financing, and shortfalls. It pulls data from the Office of the Chief Actuary of the Social Security Administration, Congressional Budget Office, the Employee Benefits Research Institute, and the Center for Retirement Research.
Here’s a sampling of interesting facts from the document:
- In 2012, about 159 million individuals or 94% of the American workforce, worked in Social Security-covered employment. (Those not covered include government employees covered by other insurance programs, farm workers who do not meet minimum work requirements and students.)
- Approximately 55 million Americans received Social Security benefits in 2011. Seventy percent were retirees; 19 percent were disability beneficiaries and 11 percent were survivors of deceased workers.
- Without Social Security income, it is estimated that nearly half senior citizens would be living in poverty. Instead, fewer than 10 percent of seniors live in poverty.
- Because the U.S. population is aging and people are living longer, the Social Security program is projected to run up a deficit. The projected shortfall is 2.67% of taxable earnings over the next 75 years.
- There are a variety of ways to compensate for the deficit including raising taxes, expanding coverage, investing in equities, increasing the retirement age and reducing cost-of-living increases.
The guide concludes that Social Security fulfills an important need in our society as an insurance program for American workers. To learn more about Social Security benefits and about how your payroll taxes are used, it’s worth checking out this evidence-based document.
Can we fend off chronic disease? The evidence says yes
September 18, 2012 By 1 Comment
We have all heard that physical fitness is an important factor in health, but how important a factor? And is it ever too late to get fit?
A study published earlier last month in the Archives of Internal Medicine suggests that becoming fit in middle age, even if you haven’t previously exercised, can stave off illness later in life.
In the study, researchers collected medical records for more than 18,000 healthy middle-aged men and women who’d visited the Cooper Institute in Dallas, Texas for a check-up since 1970. Each subject took a treadmill test to determine their aerobic fitness at their first check-up. Then the researchers checked their Medicare records from 1999 through 2009.
The study found that people who were least fit at the time of their initial check-up were the most likely to developed chronic conditions such as heart disease and cancer early in the aging process. Those who were most in middle-age developed the same conditions, but significantly later in life compared to the less fit.
The take-home message of this study actually parallels a lesson shared in Karl’s book 30 Lessons for Living, which shares advice from America’s elders. The lesson is: It’s not dying you should worry about – it’s chronic disease.
This study provides evidence that you can actually do something to help prevent chronic disease later in life – exercise!
The study is backed up by several systematic reviews. One published in the Journal of Science and Medicine in Sport found physical activity helps prevent heart disease, cancer and diabetes. Another published in Obesity Reviews found individual who are overweight but have good aerobic fitness are at lower risk of cardiovascular disease compared with individuals with normal weight and poor fitness.
The bottom line: Physical fitness can help you lead a healthier, happier life no matter what your age.
New evidence: Vitamin D helps prevent falls
August 9, 2012 By 1 Comment
Vitamin D is one of those supplements that makes it into the news media frequently. Here on EBL, we’ve written before about the U.S. Institute of Medicine’s recommendations on Vitamin D intake.
Now there is a new recommendation that taking Vitamin D supplements can help prevent falls in people over 65 years old with a higher risk of falling.
In a review of nine separate studies, the United States Preventative Services Task Force came to the conclusion a daily dose of 800 international units reduced the risk of falling by about 17 percent, compared with those who did not take the vitamin.
“The exact mechanism is not known, but it seems to help muscle strength and balance,” Dr. Al Siu, vice chairman of the task force and chairman of the geriatrics and palliative medicine department at Mount Sinai School of Medicine, told the New York Times.
The panel also made two other recommendations. Doctors should do a comprehensive assessment of patients’ risk of falling – including asking about falling history and observing patients stand up and walk – to identify those at higher risk. And patients’ should exercise to improve strength and balance.
Falls are the leading cause of injury in adults 65 and older. While there’s no sure-fire way to prevent them, we have evidence that some interventions do work. That’s important information for all of us to know.
Evidence of a need: Mental health workers
July 24, 2012 By Leave a Comment
As the U.S. population continues to age, our nation needs to give some serious thoughts to caring for an older population. In 2010, there were 40.3 million adults age 65 and older in the U.S. Over the next 20 years, that number is expected to climb to more than 72 million. With it will come a number of new challenges, many of them for our health care system.
The U.S. government released a new report last week that took an in-depth, systematic look at how the mental health care system is equipped to deal with an aging population. Their review found that there are 5.6 million to 8 million older adults in America today have one or more mental health and substance use conditions, and that number is expected to soar as the population ages.
The report calls for a number of major changes to the U.S. health care system including:
- A redesign of Medicare and Medicaid payment rules to guarantee coverage of counseling, care management, and other types of services crucial for treating mental health conditions and substance use problems so that clinicians are willing to provide this care.
- Health care accrediting organizations should make sure that health care providers who see older adults are trained to recognize signs and symptoms of geriatric mental health conditions, neglect and substance abuse.
- The U.S. Department of Health and Human Services should make it a priority to promote building a work force trained in geriatric mental health and substance abuse care.
The report also details the consequences of inattention to older adults’ mental health conditions clearly leads to include higher costs and poorer health outcomes – an outcome that our senior citizens and our health care system can’t afford.
The link between happiness and health
May 3, 2012 By Leave a Comment
A positive mood can certainly make for a brighter day, but now there’s new evidence that is also m
akes for a healthier heart.
A systematic review by researchers at Harvard University looked at more than 200 studies on cardiovascular risks and emotional state – the largest ever reviewed in one paper. They found that patients who reported a positive mental state were less likely to suffer from heart disease and stroke.
Feeling such as optimism, happiness and hope seemed to protect against cardiovascular disease independently of risk factors like smoking and obesity.
While the link provides an interesting insight, it is difficult to tell whether happiness produces health, or whether healthier people are, by nature, happier. In either case, it’s prudent to cultivate a positive mindset.
At Cornell, psychologist Anthony Ong’s research focuses on how people maintain a positive attitude, even when they experience stressful events like the loss of a loved one. His work has shown that social connectedness – having a supportive relationships with those around you – contributes these daily positive emotions, and leads people to be more resilient in the face of adversity.
The take home message: Get out in your community and cultivate some good feelings!
