Researchers from the University of Pittsburgh have added more evidence to support the link between high blood pressure and Alzheimer's disease. They studied 1,424 women aged 65 or over who had their blood pressure checked every year and who had regular MRI (magnetic resonance imaging) scans of their brains. The women who had high blood pressure at the start of the study had significantly more lesions on the white matter in their brains than those with normal blood pressure. The lesions were more common in the frontal lobe of the brain which controls emotions and plays an important part in people's personality.
