Angiotensin receptor blockers (ARBs) are drugs used to treat high blood pressure but they could also help to stave off and slow down Alzheimer's disease. Researchers from Boston University School of Medicine studied the records of five million people on the database of the U.S. Department of Health (Veterans Affairs) and compared those who were taking ARBs with those who had similar blood-pressure problems but who were taking different drugs. They found that patients taking ARBs had up to a 50% lower chance of getting Alzheimer's disease or dementia, and those who took another kind of drug, angiotensin converting enzyme (ACE) inhibitors, as well had a 55% lower risk. Those who already had Alzheimer's disease or dementia had a 67% lower chance of being admitted to nursing homes or dying if they were taking both types of drugs.
