降压药或可治痴呆

   Medicines used to treat high blood pressure and heart disease may cut the risk of developing Alzheimer’s disease and dementia. Researchers from Boston found that older people taking a certain type of blood pressure medication known as angiotensin receptor blockers were significantly less likely to develop the brain-wasting illnesses. Dementia affects some 35 million people around the world and the number of cases is set to grow dramatically as global populations age.
