New research hints that even a simple exercise routine just might help older Americans with mild memory problems.
FILE - High school students run at sunset as they practice for the track and field season Monday, Feb. 28, 2022, in Shawnee, Kan. New research hints that even simple exercise just might help fend off memory problems. 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.After a year, cognitive testing showed overall neither group had worsened, said lead researcher Laura Baker, a neuroscientist at Wake Forest School of Medicine. Nor did brain scans show the shrinkage that accompanies worsening memory problems, she said.
But the results suggest “this is doable for everybody” -- not just seniors healthy enough to work up a hard sweat, said Baker, who presented the data Tuesday at the Alzheimer's Association International Conference. ”Exercise needs to be part of the prevention strategies" for at-risk seniors. While amyloid clearly plays a role, it's important that drugmakers increasingly are targeting many other factors that can lead to dementia, Carrillo said, because effective treatment or prevention likely will require a combination of customized strategies.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.
Hence the social stimulation — which she credited with each participant completing over 100 hours of exercise. Baker suspects that sheer volume might explain why even the simple stretching added up to an apparent benefit. Participants were supposed to exercise without formal support for an additional six months, data Baker hasn't yet analyzed.
