There's new research that suggests brain training with computer exercises can cut the risk of Alzheimer's disease. In array of new research findings is showing how a rich mental life, and potentially a specific type of brain exercise, may act as bulwarks against the onset of dementia. The results are being presented this week at the Alzheimer’s Association International Conference, the world’s largest gathering of researchers in the field that kicked off in Toronto on Sunday. Among the most intriguing data to emerge at the meeting are those coming from a long-running and randomized controlled experiment called the ACTIVE study, which, for the first time, appears to show that a particular form of brain training may confer a level of protection from dementia as subjects age. The idea is a controversial one because of the proliferation of computer-based “brain games” whose claimed effectiveness against cognitive decline is generally not supported by the scientific literature. But Jerri Edwards, the University of South Florida researcher who presented the result, said that a task specifically tailored to boost mental processing speed appears to have a lasting effect. “The idea is that you improve a very basic ability and that is going to have broader transfer,” she said.
They’re the go to shoes of summer. You can get in and out of them quickly. But experts say many disregard the long-term injuries flip flops can cause. Global News spoke to a chiropractor to understand how flip flops are bad for you. You wear them on vacation, when you’re grocery shopping, even when you’re out with friends on a hot summer day. Flip flops are a summertime wardrobe staple but should you be wearing them while you’re on your feet all day? “They can have such fun designs on them and it’s a quick kind of footwear…because it’s so enticing, people don’t look at the injury you can get from them,” Dr. Katherine Tibor, a Toronto-based chiropractor and Ontario Chiropractic Association spokeswoman, told Global News. Here’s a handful of ways flip flops tamper with your feet:
Have you ever used the phrase “My feet are killing me?” There may be something to it. Our feet bear the weight of our whole bodies. They contain 25 percent of the body’s bones, 33 joints and 100 tendons, muscles and ligaments. They also contain countless nerves and blood vessels that link to your heart, spine and brain. Problems with the feet can indicate a more serious condition in another part of your body. Here are four of the issues that may mean you should go see a doctor:
An Israeli start-up says it has developed a personality prediction program that could help police and security services spot people with malign intentions, but an independent security expert says it could harm individual freedom. Counter-terror experts say the firm must improve its 86 percent successful detection rate for it to be useful in airports. Civil liberties campaigners might say it shouldn't be used at all.
When the dental hygienist asks “Have you been flossing?” – what do you say?
It turns out a lot of Americans aren’t picking up the floss, according to new survey data from the Centers For Disease Control.
A British medical journal says women are still widely under-represented in medical research studies. Women are badly underrepresented in health research, including sport and exercise studies and even drug trials, and a big reason for the potentially dangerous disparity is their monthly period, experts say. An editorial in the British Journal of Sports Medicine looked at the gender gap in sports and exercise research and found menstruation is the major barrier. Dr. Jerilynn Prior, a professor of endocrinology at the University of British Columbia, says men are not adequate replacements for women in research. "Not scientifically correct. Period. Full stop," she told CBC News. Excluding women from drug trials creates an imbalance, she says. Millions of women and men are prescribed the same drugs every day. Yet some of those drugs were tested only on men. "Half the human race doesn't have accurate information about the response to whatever the intervention is," Prior said. "It's like comparing apples and oranges."
Changing residences frequently in childhood may be bad for your health.
Using Danish government health data, researchers cataloged various adverse events — suicides or suicide attempts, violent criminality, mental illness, substance abuse, psychiatric diagnoses and premature death — in 1,475,030 Danes born from 1971 to 1997. Then they correlated these problems with the number of times each person had moved before age 15.
We spend two full years of our lives washing ourselves. How much of that time (and money and water) is a waste? As we learn more about the relationship between the microbiome and our health, some scientists and journalists have begun weaning themselves from cosmetic products like soap and shampoo. In taking away the bad bacteria, we could be losing too much of the good. Applying detergents (soaps) to our skin and hair every day disrupts a sort of balance between skin oils and the bacteria that live on our skin. When you shower aggressively, you obliterate the ecosystems. They repopulate quickly, but the species are out of balance and tend to favor the kinds of microbes that produce odor.
Many people have used them at least once, those car air fresheners that dangle from your rear view mirror, but researchers have found chemicals used in air fresheners can also be bad for your health. Because many of the car air fresheners are made overseas, it is hard for consumers to tell exactly what is in them, but anecdotal evidence indicates, they can lead to respiratory irritation. Research on the Internet turned up other instances of damage from air fresheners in contact with car interiors, and it turns out many of the fragrance oils used for the cardboard air fresheners–and the liquid varieties–are derived from petroleum.
Some deodorant commercials make men appear to be irresistible to women if they put on a certain product. A new study shows there may be scientific truth to these cheesy advertisements. Researchers in the United Kingdom say wearing deodorant could make women perceive men as more masculine. Scientists have known for a long time that natural human body odor can influence how attracted we are to someone, but this research looks at how we conceal our natural body odor, and the impact it can have.
