Seniors who suffer from chronic health conditions like high blood pressure or heart disease often develop a host of other, seemingly unrelated health problems, including cognitive impairment like memory loss and dementia, according to a new study based on data collected by the National Center for Health Statistics.
For the study, the researchers analyzed the medical records of hundreds of thousands of seniors residing in assisted-living facilities and found that most had at least one chronic health condition. What was more alarming, however, was that many had overlapping ailments. While high blood pressure and heart disease were most common, nearly half of the assisted-living residents showed signs of dementia.
“These findings suggest a vulnerable population with a high burden of functional and cognitive impairment,” the authors of the study report wrote.
Many studies have suggested a link between vascular disease and dementia, particularly Alzheimer’s, said Dr. P. Murali Doraiswamy, a professor for psychiatry and behavioral sciences at Duke University’s Institute for Brain Sciences (DIBS). Therefore it may not be possible to treat dementia without treating vascular problems, he added.
But that may be easier said than done. “We don’t universally do a great job of how we treat conditions that overlap, for example Alzheimer’s and high blood pressure,” said Dr. Cythia M. Boyd, an associate professor of geriatric medicine at the John Hopkins University Center on Aging and Health, to the New York Times. “Much of the way we practice medicine is looking at disease by disease. We aren’t doing enough thinking about how to add them together and really integrate care.”
What makes things more complicated is that most doctors are not sufficiently trained in preventing or reducing lifestyle-related illnesses – not in the general public and certainly not in older patients – other than through medicating. For instance, the importance of nutrition as a part of preventive care is rarely ever mentioned in medical schools. The approximate time devoted to nutrition science over the first two years of medical education is six hours, which is clearly inadequate, according to the National Academy of Sciences. The same goes for other health-promoting measures such as exercise, especially for the aging population.
Yet many studies have provided compelling evidence that diet and exercise play a significant role for physical and mental health at any time in life but increasingly so as we age.
For example, a more recent study from Britain concluded that the so-called “Western diet,” which typically includes fried, sweet and processed foods, red meat, refined grains and high-fat dairy products, increases the risk of chronic diseases, which in turn can adversely affect both physical and mental health in later years. Eating a Western diet makes it less likely to have an ideal aging process, says Dr. Tasnime Akbaraly, a researcher at the University College of London and lead author of the study report. Conversely, making dietary improvements can yield multiple benefits in this regard.
There is also further evidence that exercise can give a boost to the aging brain. Scientists at the University of British Columbia found that older women who suffered from mild cognitive impairment could improve their memory through weight training and brisk walking.
The connections between physical and mental decline may not yet be completely understood, but it seems clear that chronic diseases play a major role in the process. While these are widespread, the encouraging news is that many, if not all, are preventable by healthier lifestyle choices.

It shouldn’t come as a big surprise. On average, Americans are in poorer health and have shorter lifespans than the citizens of other affluent countries, including most Western European nations, Australia, Canada and Japan. Considering that close to 50 million people, almost 20 percent of the population, are without health insurance and many more with only limited access to medical services, a decline in public health would seem inevitable. Still, the findings of a recent study by the U.S. government are quite shocking.
According to the Institute of Medicine (IOM), America currently ranks at or near the bottom among the 17 richest nations in the world in terms of life expectancy and chronic diseases like heart disease, lung disease, obesity and diabetes as well as injuries and death from violence and sexually transmitted diseases.
What’s even more disturbing is that these statistics not only apply to the poor and the elderly, as experts long expected, but across all demographics, including young adults and those who can afford health care coverage.
“We are struck by the gravity of these findings,” said Dr. Steven Woolf, professor of medicine at Virginia Commonwealth University and chairman of an expert panel that was tasked with the study. “What concerns [us] is why, for decades, we have been slipping behind.”
Even first generation immigrants coming to the U.S. show negative health effects within a relatively short time due to diet and lifestyle changes. According to the National Institute of Health (NIH), obesity rates among immigrants roughly equal those of U.S.-born adults within 10 to 15 years after taking up residence here. One study found that migrants from comparatively poor countries like Mexico or Guatemala are especially prone to develop diseases like obesity, diabetes and heart problems because of dietary changes.
“If you go with the flow in America today, you will end up overweight or obese, as two-thirds of all adults do,” said Dr. Thomas Frieden, director of the Centers for Disease Control and Prevention (CDC) in an interview with USA TODAY. “Obesity is one of the few things that has gotten worse quickly. It really is a very serious health problem,” he added.
The obesity epidemic is also one of the main reasons why it is so hard to get health care costs under control in this country. It costs $1,400 more per year to treat an obese patient compared to someone who is normal-weight and $6,600 more to treat a diabetic, said Dr. Frieden.
What changed in the U.S. more profoundly than in other countries – although similar trends are now emerging worldwide – is a dramatic shift in our eating habits. We eat more conveniently prepared but highly processed foods and enjoy fewer healthy meals made from scratch. Our portion sizes have gone through the roof. We also have become more sedentary due to progressive automation in the workplace, longer commutes and lack of safe outlets for physical activity.
“What has happened is that the structure of our society has changed in ways that make it difficult to maintain a healthy weight,” said Dr. Frieden. It’s a fertile ground for the diseases we now see on an epidemic scale.
Obviously, there is not one solution that could undo all of these regrettable developments. Multiple measures will have to be put in place and made to work together. Personal responsibility is certainly part of the equation, but so are numerous other components such as better health and nutrition education for the public, further improvements to school lunch programs, reintroduction of mandatory physical education (PE), more effective safety and disclosure regulations of agricultural and food manufacturing industries, to name just a few.
The current deterioration of our public health is not irreversible. On the contrary. Most of our ailments are self-inflicted and therefore in our control if we only muster the will to address them in meaningful ways.

There are multiple causes for the so-called lifestyle-related diseases that plague us today. Obesity, diabetes, heart disease and hypertension can mostly be blamed on poor nutrition, lack of exercise, stress and, as scientists increasingly find out, sleep deprivation.
Over the last few decades, Americans have kept cutting back on their sleep as their lives have become busier. Long hours spent on work, commutes, kids’ activities and household chores leave less and less time for rest. While a few generations ago people slept for eight hours or more, most Americans have to get by on six hours or less today.
And it’s not only the difference in the amount of time but also the quality of the rest we get that has turned us into a nation of chronically sleep-deprived zombies.
“Sleep deprivation is reaching epidemic proportions and may soon be our nation’s number one health problem,” says Cindy Heroux, a Registered Dietitian and author of “The Manual That Should Have Come With Your Body.”
“When you don’t get enough sleep, you are more likely to suffer from certain chronic illnesses, including diabetes and heart disease. You are also more likely to gain weight or become obese,” she says.
What is the connection? Sleep deprivation can lead to disruption of your metabolism, which in turn can make the cells in your body more insulin resistant. Insulin resistance causes the cells to think they are being starved and, as a result, urgent hunger signals are dispatched to the brain, making you want to eat. That is one of the reasons why people reach for food when they are overtired or stressed out.
A recent study published in the “Journal of Clinical Endocrinology and Metabolism” concluded that even short-term sleep deprivation can activate the appetite-controlling part of the brain, increasing hunger levels. Researchers have calculated that for each hour a person cuts back on sleep, he or she consumes an average of 360 additional calories. If extra calories are not burned off, they are stored as fat and insulin resistance increases even further. It’s a vicious cycle and the negative health effects can be multiple.
Some experts say that it’s not just the perpetual lack of sleep that makes Americans sick but also the ways we are trying to cope with being chronically sleep deprived. Too many people just muddle through their tiredness, says Dr. Matthew Edlund, author of “The Power of Rest.” He believes that the widespread reliance on energy drinks like “Red Bull,” “Monster” and “5-Hour Energy” does potentially more harm than users realize.
“We don’t use our bodies the way they’re built to be used,” he says. “We guzzle energy drinks and then can’t sleep at night. We sit all day and then read e-mails at 3 a.m. It’s no wonder we walk around like zombies and treat these drinks like liquid life support. It’s a good time to question these trends and find healthier ways to power up.”
Instead of using energy boosters that work short-term but eventually only add to the exhaustion resulting from sleep deprivation, nutrition experts recommend protein-rich snacks like low-fat yogurt or cheese or peanut butter. In the end, however, there is only one solution and that is getting regularly a good night’s sleep.
