Late-life high blood pressure may harm the brain

How might high pressure do harm?

“Lower blood pressure reduces the risk of those blood vessel blockages” that can cause a silent stroke, said another independent expert, the Mayo Clinic’s Dr. David Knopman. The work shows that “treating blood pressure throughout the lifespan is important.”

Knopman is a spokesman for the American Academy of Neurology, whose journal, Neurology, published the study. Federal grants paid for the work.
