A study by researchers from the University of Alabama in Birmingham has added more evidence for the link between high blood pressure and cognitive impairment and dementia. They studied 19,836 people. 1,505 of them (7.6%) had cognitive problems and 9,844 (49.6%) were taking medication for high blood pressure. The researchers found a link between high blood pressure and cognitive problems which held true even when other factors such as age, smoking, exercise, education, diabetes and high cholesterol were taken into account. Other research has shown that high blood pressure can weaken small arteries in the brain leading to damage.
