Physical activity seemed to influence their brain’s health, their thinking abilities and whether they experienced the memory loss of Alzheimer’s disease. Afterward, the microglia release other chemical messages that calm the inflammation, keeping the brain healthy and tidy and the animal’s thinking intact.But as animals age, recent studies have found, their microglia can start to malfunction, initiating inflammation but not subsequently quieting it, leading to continuous brain inflammation. The researchers also looked for common biological hallmarks of Alzheimer’s disease, like the telltale plaques and tangles that riddle the brain. “But there was a linear relationship” between how still they were and their brain health, she said. Finally, it does not tell us whether we get extra brain benefits from being physically active when we are far younger than 80-plus.
