| Regular exercise can help keep your brain healthy as you age Posted: 23 Oct 2012 08:41 AM PDT EDINBURGH, Oct 23 —As we get older, one of the best ways to keep our brains sharp is by moving our bodies, researchers claim in a new study. University of Edinburgh researchers found that for people over 70 years old, regular exercise slowed down brain shrinkage — which is associated with memory and cognitive problems — over a period of three years, compared to people who did little exercise. Plus the exercisers had fewer "damaged" areas in their brain's white matter and more grey matter, the parts of the brain with nerve cell bodies, than those subjects who weren't as active. To reach their findings, the team used MRI scans to measure the volume of brain tissue and the health of the brain's white matter in nearly 700 people, according to a press release on Monday. "Our results suggest that to maintain brain health, physical activity may be more beneficial than choosing more sedentary activities," says lead researcher Dr. Alan Gow. Until more work can be done to further understand the effect of exercise on the brain, Gow adds that for now, "increasing physical activity — even a short walk each day — can only be encouraged." "We already know that exercise is important in reducing our risk of some illnesses that come with ageing, such as cardiovascular disease and cancer," adds Dr. James Goodwin, head of research at Age UK, which funded the project. "This research reemphasises that it really is never too late to benefit from exercise, so whether it's a brisk walk to the shops, gardening or competing in a fun run, it is crucial that those of us who can, get active as we grow older." The findings were published Tuesday, October 23, in the journal Neurology. http://www.neurology.org/content/79/17/1802 — AFP-Relaxnews

| Chew on this: gum cures motion sickness Posted: 23 Oct 2012 05:59 AM PDT NEW YORK, Oct 23 — Suffer from travel-related nausea and sickness? Researchers out of Iran have created a medicated chewing gum that can help alleviate all that ails you. Presented at the 2012 American Association of Pharmaceutical Scientists annual meeting in Chicago last week, the prototype was developed to enable faster absorption through the cheek and act quickly to cure symptoms like nausea, dizziness and vomiting. It's estimated that about 33 per cent of people are susceptible to travel sickness in mild circumstances and 66 per cent are affected in more severe conditions, researchers say. Motion sickness occurs when there's a conflict between what the eyes see and what the inner ears, muscles and joints sense, particularly common when traveling by car, train, airplanes and boats. The new gum, created out of the Islamic Azad University School of Pharmaceutical Sciences in Tehran, is made with dimenhydrinate, among the best drug candidates for treating the condition, researchers say. The drug is also marketed under brand names like Gravol, Dramamine, Vomex and Gravamin. Researchers say delivering the drug as a chewing gum is a faster and more effective way to tackle motion sickness. Meanwhile, here are a few other non-medicinal ways to avoid travel-related sickness: · Choose a seat at the front of cars, trains, or the upper deck on a boat. On a plane, try to sit by the wings. · Fix your gaze on a stable object in the distance and avoid reading or playing games. · Keep your head as still as possible with the aid of a pillow if possible · Try closing your eyes and listening to music · Avoid eating large meals or drinking alcohol before traveling · If possible, open the window or move to the top deck of a ship to get fresh air --Source: National Health Service UK — AFP-Relaxnews |
