Physical activity associated with slower cognitive decline in people with high levels of tau protein

Engaging in high or medium levels of physical activity was associated with slower rates of cognitive decline in people with high or low levels of tau, compared to those with little physical activity. Led by researchers from the Rush University Medical Center, the findings were published in JAMA Network Open on Aug. 11. The researchers noted that measuring levels of tau, a protein that is a hallmark of Alzheimer’s disease, in the blood could help identify people who might benefit from early intervention to slow cognitive decline.
