If You Can't Stand On One Leg For 20 Seconds, Here's What It Could Say About Your Brain

The 20-Second Test To Determine Your Brain Health

What if we told you that trying to stand on one leg for 20 seconds (or more) could help you gauge the health of your brain? You might think we were a bit unbalanced ourselves. But that's exactly what a new study published in the journal Stroke suggests.

Researchers at the Center for Genomic Medicine at Kyoto University in Japan asked about 1,400 people (average age 67) to stand with one leg raised and their eyes open for up to 60 seconds. Everyone tried this twice; best times were used for analysis. Then, using MRI, the researchers scanned everyone's brain. 

They found that those who struggled to balance for 20 seconds had cerebral small-vessel disease (SVD), even though they weren't exhibiting any classic symptoms. SVD is related to stroke, dementia and even Parkinson's. Among the balance-impaired, 15% had one micro-bleed brain lesion (30% had two) and 16% had one arterial brain blockage (35% had two.) In addition, those with the shortest balance times generally had the lowest mental performance scores.


How can standing on one leg provide insight into the brain's health? "Balance is achieved and maintained by 3 main sensory circuits," explains Jose Biller, MD, chair of neurology at Loyola Medicine in Maywood, IL. "Vision, proprioception [your sense of body position] and the vestibular system [inner ear, etc.]." If you were paying attention in high school anatomy, you'll remember that the brain controls all these sensory circuits. So any loss of motor coordination, such as the inability to balance for any length of time, could suggest brain damage.

So take the balance test to see how you do. If you can't break that 20-second threshold then, according to  Biller, you may be at increased risk for brain disease and cognitive decline. Consult with your physician.


8 Seemingly Innocent Habits That Could Take Years Off Your Life

Innocent Habits That Could Take Years Off Your Life
You know the biggies: Don't smoke, stay out of the sun, and go easy on the processed food. But if you really want to maximize your chances of living forever (or, okay, if not forever than just for a really long time—and healthily), you need to pay attention to some lesser-known culprits, too. Here are 8 habits to start avoiding:

Obsessing about your age.

Does the thought of another birthday make you bristle? Believe us, you aren't alone. But it's best to check your attitude, because dwelling on it can have serious implications for the aging process. Fixating on the negative parts of getting older, like mental decline, could actually make you feel older, according to research from Purdue University. The good news? The secret to feeling younger is within your control: it’s as easy as believing that you are younger. (Need age-embracing inspiration?

A nut-free diet.


Unless you're allergic, you may want to add nuts to your snack rotation. Results from two long-term Harvard studies show that daily nut-eaters were less likely to die of cancer, heart disease, and respiratory disease—in a 30-year study follow-up they were found to be 20% less likely to die overall. Whether it's walnuts, almonds, peanuts, pistachios, or another variety (preferably unsalted), a handful or two a day will do the trick.

Acting stingy.

Here's one more reason that it's better to give than receive: Altruistic acts could promote longevity. A study published in the American Journal of Public Health suggests that helping others reduces stress and, ultimately, lowers your risk of dying. Generosity really is the gift that keeps on giving.

Sitting all day long.

If you spend most of the day in the seated position, it's time to take a stand. A study published in journal BMJOpen found that sitting for more than three hours a day can reduce life expectancy by two years. But what if you have a desk job? Do your best to get up periodically throughout the day to take a quick walk, get on your feet while you take phone calls, and see if your company can provide you with a standing desk. Every little bit helps.

Staying up all night.

Whether you work the graveyard shift or just happen to hit your stride when the sun goes down, there's a dark side to rising with the moon. Sleeping too little or consistently sleeping against your body's biological clock raises your risk of type 2 diabetes, obesity, heart attack, and stroke, all to varying degrees. Less sleep is also thought to accelerate the brain’s aging process, according to research from Duke-NUS Graduate Medical School's Center for Cognitive Neuroscience. And the list of reasons to catch more zzzs continues. (If you have trouble sleeping, these 20 simple tips can help.)

Being down in the dumps.

A lingering gloomy attitude isn't just a bummer—it could also endanger your health. Women who are jealous, anxious, or moody and distressed in middle age may be at higher risk for developing Alzheimer's later in life, according to a nearly 40-year study published by the American Academy of Neurology. The silver lining is that reducing your risk is as simple as working on your attitude. If you can't get out of a funk yourself, consider talking to a therapist.

Walking slowly.

Pounding the pavement at any pace is a great form of exercise, but a study of 39,000 walkers from the Lawrence Berkeley National Laboratory found that over a decade, the death rate was highest among the slowest strollers, even if they expended the same amount of energy as someone walking briskly for a shorter time period. You want to aim for 23 minutes per mile or faster to lower your mortality risk; use a pedometer on your next walk to pick up the pace.

Living with sexual frustration.

A study published in Biological Psychology found that people who recently had sexual intercourse had lower blood pressure than those who didn't. And a study from the University of Michigan Health System suggests that sex could be one of the secrets to youth, well-being, and a longer life. In the study, male fruit flies that were exposed to the sexual pheromones of their female counterparts without the opportunity to mate experienced increased stress and ultimately lived shorter lives. Granted, this study was performed on fruit flies, so we can't make any promises. But isn't it worth a try?
