The cholesterol-lowering drugs statins have been linked to a reduced risk of dementia (see below) and now researchers have found that angiotensin receptor blockers (ARBs) can also reduce the risk of the condition. Using data on more than 5 million people scientists from Boston University School of Medicine compared those people taking ARBs with those of similar health status who were taking different medication. Patients taking ARBs had about a 35-40% lower chance of developing Alzheimer disease or dementia. In patients already suffering from these illnesses people taking ARBs had a 45% lower chance of developing delirium, being admitted to a nursing home or dying.
