HealthDay (1/10, Thompson) reports, “Older folks who are more physically active have higher levels of a protein that promotes better communication between the brain’s synapses,” investigators concluded in an autopsy study that “involved more than 400 elderly people who” had during their lifetimes “agreed to wear monitors that tracked their amount of daily physical activity.” The study revealed that the brains of more active people “contained higher levels of…synaptic proteins.” Such proteins “are involved with the production and release of neurotransmitters, the biochemicals in the brain that promote communication between nerve cells.” The findings were published online in Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association.
