Vitamin B12 can do all sorts of good things for older folks. It can support everything from brain health to how your nerves function. Some studies suggest it may even help prevent cognitive decline. But Kristin Zimmerman, associate professor in the department of pharmacotherapy and outcomes science at Virginia Commonwealth University’s School of Pharmacy in Richmond, grew suspicious several years ago when her mom, who was in her late 60s and living on Florida’s Gold Coast, qu

Tongue Lashing Few muscles are as hard-working as the tongue. By day, it twists to form the sounds you speak and pushes around the food you eat. While you sleep, your tongue moves saliva down your throat.  Go With Your Gut On average, your intestines are 25 feet long from end to end. Your small intestine is long -- over 20 feet. And while your large intestine is wider around, it stretches out only to 5 feet in length. Dirty Mouth You might think twice before kissing. In one m

Try this: Bend your wrist as far back as you can toward your forearm. How long can you hold it there? Probably not long, maybe a matter of seconds, says Scott Bautch, D.C., a Wisconsin-based chiropractor and president of the American Chiropractic Association’s Council on Occupational Health. Bautch asks people to do this to prove a point. “You wouldn’t watch an entire football game with your wrist stretched as far as possible, your arm way above your head, or your pelvis twis

Age Alzheimer’s disease is the most common form of dementia. About a third of people 85 and older show signs of the disease. The genes you get from your parents play a part at this age, but so do things like diet, exercise, your social life, and other illnesses. Dementia isn't a normal part of getting older. Heart Disease It could lead to a heart attack or stroke, which makes dementia more likely. Heart disease is usually caused by plaque buildup in arteries around your heart

People who have razor-sharp minds in their 80s and 90s — known as “SuperAgers” — produce twice the number of young neurons as cognitively healthy adults and 2.5 times as many as people with Alzheimer’s disease, a new study found. “This shows the aging brain has the capacity to regenerate — that’s huge,” said study coauthor Dr. Tamar Gefen, an associate professor of psychiatry and behavioral sciences at the Mesulam Institute for Cognitive Neurology and Alzheimer’s Disease at N

All the Shades of Gray It’s said a woman’s hair is their crowning glory. Sooner or later, that crown will start to gray. You now face a decision. Banish gray hair with dye, or rock a silver mane? Whichever you pick, know the facts about your gray strands to keep your hair looking and feeling its best. Science of Grays Your hair follicles have pigment cells that make melanin, a chemical that gives your hair its color. As you age, these cells start to die. Without pigment, new

If your knees creak or your hips feel stiff when you get out of bed in the morning, you might blame it on the normal wear and tear that comes with age. But the stiffness could also be something else: a problem with joint lubrication. A natural lubricant called synovial fluid helps your bones glide together without grinding, says Dr. Kenneth Mautner, a sports medicine physician at Emory Healthcare’s Orthopaedics and Spine Center in Atlanta. As we age, our bodies can produce le

Sleep is vitally important at all ages, but a myth persists: older adults simply need less sleep. But in fact, people who are 65 and older are still recommended to get the same amount of sleep as younger adults. “As we age, we still need around 7–9 hours of sleep, but the way we sleep shifts. Sleep tends to become lighter and more fragmented, meaning older adults wake up more during the night. This can be due to natural changes in our internal body clock, certain medications,

It’s normal to feel a bit nervous about visiting the dentist. Things like needles, drills, and sharp tools are enough to unnerve anyone, regardless of their age. But if you’re 65 or older, it can be especially hard to smile when thinking about your teeth. That’s because older adults are at higher risk for certain dental issues. Maybe your mouth feels dryer than it used to. Perhaps your dentist has recommended some procedures you’ve never heard of. And you might find out you h

The “forever chemicals” known as PFAS appear to be aging men faster in their 50s and early 60s, a new study found. Called forever chemicals due to the years it takes for them to break down, perfluoroalkyl and polyfluoroalkyl substances are present in the blood of an estimated 98% of Americans, according to the National Academies of Sciences, Engineering, and Medicine. Epigenetic aging — a measurement of one’s biological age instead of chronological age — was most advanced in

Scientists have just identified four broad types of medical condition that could help doctors identify the risk of Alzheimer’s disease a decade before symptoms develop—with the potential to help slash incidence rates in half.  Alzheimer’s disease develops over decades, and some health conditions in midlife such as hypertension, hyperlipidemia and stroke have been linked to an increased risk later in life.   However, more medical conditions could predict the development of thi

Glyphosate is an ingredient found in several herbicide products, including those from a major brand that has been in the news for settling a lawsuit around glyphosate’s potential link to cancer. Recent research links glyphosate to Hodgkin’s lymphoma and raises questions about the ingredient’s carcinogenic properties, however, more research is still needed. What is glyphosate? Glyphosate is an herbicide that’s widespread in the environment. “It was initially registered as an

We get it: Absolutely no one wants cancer or even wants to think about getting cancer. The good news is that we’ve come a long way in treatment and prognoses for many types of cancer, especially when doctors catch them early , thanks to research and modern medicine. Yet, despite all we’ve learned about the disease, there are still a bunch of things we don’t know. “We are still trying to figure out risk factors for many types of cancer,” states Dr. David Yashar, MD , a hemato

After a trip, a long day with family or the occasional late night, it’s common to feel tired or a bit sluggish. But fatigue — constant exhaustion, tiredness, and a lack of physical and mental energy — often needs more than just a good night’s sleep to resolve. Often, fatigue is seen as an inevitable part of aging — but this shouldn’t be the case, according to Chris Aakre, M.D., a fatigue specialist at Mayo Clinic in Rochester, Minnesota. “Fatigue at any age is not normal. The

You don’t have to cut the morning caffeine drip to protect your brain against dementia in the future. New research shows that daily coffee or tea –– and yes, the caffeinated kind –– is associated with better cognitive health in the long term. Those who enjoyed two to three cups of coffee or one to two cups of tea a day saw the biggest impact, according to the study published Monday in JAMA. Coffee drinkers in midlife had about an 18% lower chance of developing dementia later

A person’s genes play a far greater role in likely lifespan than previously thought, according to a major new study published Thursday in the journal Science . Using data from human twin studies, an international team of researchers arrived at the conclusion that the genetic contribution to how long we’re likely to live is as high as 55%. This new finding is strikingly higher than previous estimates, which have calculated the role of genetics in lifespan could range from 6% t

There are more than 2 million new cancer cases diagnosed each year in the United States, and cancer is the country’s second leading cause of death. Most cancers are caused by factors outside your control, but at least 42% of new cases are potentially avoidable. Strategies that can lower your risk often improve your overall health. ‘I’ve Been Intentional About Having Fresher Foods’ Research has repeatedly linked ultra-processed foods—generally those with a long shelf life that

It’s likely that you might have taken your health for granted in early adulthood. Maybe you could run a quick mile or stand on your feet all day long at a theme park. However, as you age, you may notice that your body doesn’t usually work as well as it used to. For example, after the age of 50, bone breakdown happens quicker than formation, which results in bone loss. That said, there are daily habits and practices that older adults can engage in to help ease some of the ache

Can you help your brain stay healthy as you age by doing things that challenge your mind? Could that also help you avoid memory loss, or even prevent or delay dementia such as Alzheimer's? Scientists need to do more research to find out for sure. But a number of studies show there are benefits to staying mentally active. Here’s what we know about the impact of exercising your brain. Can brain exercises help delay memory loss or dementia? When people keep their minds active, t

Step into any suburban garage and you’ll see the relics of January resolutions that have fallen by the wayside. Whether it’s a piece of cardio equipment, a label maker, or a spiderweb-covered juicer, these items often stick around far longer than our motivation. Each New Year can feel like the perfect time for dramatic and sweeping changes, but those big shifts don’t always stick, especially when we attempt several at once. In fact, research shows that small goals are far eas
