An experimental blood test used in several studies to detect Alzheimer’s disease is reportedly proving highly accurate and boosting hopes that it will soon become a simple way to finally diagnose the form of dementia. 

The testing identified people with Alzheimer’s vs. no dementia or other types of it with accuracy ranging from 89% to 98% and was discussed Tuesday at a medical conference, according to the Associated Press. 

Scientists have long sought a simple, accurate way to detect the disease. Though they said the new method shows much promise, they also warned it still needs more study and is not yet ready for wide use.
