New research hints that even simple exercise just might help seniors with mild memory problems — and while physical activity helps keep healthy brains fit, it's not clear how much it helps once memory starts to slide
Another key component: Participants in both groups were showered with attention by trainers who worked with them at YMCAs around the country -- and when COVID-19 shut down gyms, helped them keep moving at home via video calls.
Those early findings are surprising, and the National Institute on Aging cautioned that tracking non-exercisers in the same study would have offered better proof. But the new study is especially intriguing because the pandemic hit halfway through, leaving already vulnerable seniors socially isolated -- something long known to increase people’s risk of memory problems, Carrillo said.
One example of a new approach: Sometimes in dementia, the brain has trouble processing blood sugar and fats for the energy it needs, John Didsbury of T3D Therapeutics told the Alzheimer's meeting. His company is testing a pill that aims to rev up that metabolism, with results expected next year. How much and what kind of exercise? In Baker’s study, seniors were supposed to get moving for 30 to 45 minutes four times a week, whether it was on a vigorous turn on the treadmill or the stretching exercises. That’s a big ask of anyone who’s sedentary, but Baker said MCI’s effects on the brain make it even harder for people to plan and stick with the new activity.
