Low-fat dairy is often seen as a healthful alternative to the full-fat kind. But according to a new study, consuming higher amounts of low-fat dairy may raise the risk of Parkinson's disease. Researchers found that the risk of Parkinson's disease was greater for adults who consumed at least three servings of low-fat dairy products every day, compared with those who consumed just one serving.
Scientists hope they have found a drug to stop all neurodegenerative brain diseases, including dementia. In 2013, a UK Medical Research Council team stopped brain cells dying in an animal for the first time, creating headline news around the world. But the compound used was unsuitable for people, as it caused organ damage. Now two drugs have been found that should have the same protective effect on the brain and are already safely used in people.
