An intriguing new study shows how exercise may bolster brain health. The study, which was in mice, found that a hormone produced by muscles during exercise can cross into the brain and enhance the health and function of neurons, improving thinking and memory in both healthy animals and those with a rodent version of Alzheimer’s disease. Earlier research shows that people produce the same hormone during exercise, and together the findings suggest that moving could alter the trajectory of memory loss in aging and dementia.
We have plenty of evidence already that exercise is good for the brain. Studies in both people and animals show that exercise prompts the creation of new neurons in the brain’s memory center and then helps those new cells survive, mature and integrate into the brain’s neural network, where they can aid in thinking and remembering.
