High blood pressure and the aging brain

From "High blood pressure hard on the aging brain" by Will Boggs, MD:

High blood pressure is associated with more deterioration in brain function than normal blood pressure in people aged 60 and older, according to a report by doctors at Howard University Hospital in Washington, DC.

"Optimal control of blood pressure may be beneficial in attenuating the risk of cognitive decline as the population ages," they conclude.
