A Boost for Aging Brains

Johns Hopkins Health Review, 2016 (EXERCISE)
Exercise energizes the brain, and understanding how this happens may lead to therapies for age-related neurological degeneration and diseases. As we age, our brain cells may stop producing enough energy to remain fully functional, and diseases like Alzheimer’s can complicate matters. A team of scientists at Johns Hopkins Medicine and the National Institute on Aging’s Intramural Research Program studied mice as they ran on wheels and found that the rodents had increased levels of a protective enzyme in their brains, which may subsequently boost energy levels in brain cells.
