Even if genetics dictate you are at high-risk for Alzheimer’s, exercise might buy you the most valuable of all resources: time. (HealthDay)
Folks with elevated levels of a brain protein called beta amyloid tend to be more likely to develop Alzheimer’s disease and experience rapid brain decline later in life, previous research has found.
But apparently they can delay the onset of Alzheimer’s through regular exercise, scientists report.
“People who had elevated levels of amyloid, which is one of the earliest changes you see with Alzheimer’s disease, had slower rates of cognitive decline and brain volume loss over time if they had greater levels of physical activity,” said lead researcher Jennifer Rabin. She is a scientist with the Hurvitz Brain Sciences Program at the Sunnybrook Research Institute in Toronto.
It didn’t take much exercise to enjoy this protection, either.
Data suggests people who walk 3.5 to 4.5 miles per day “significantly delayed the onset of Alzheimer’s,” according to Rabin.
