Scientists at UCLA may have discovered a way to spot early stages of Alzheimer's Disease years before symptoms show up.
The study in Thursday's edition of the New England Journal of Medicine shows the use of brain scanning technology may help identify abnormalities that may cause the disease.
"If we can make diagnosis much of it before clinical diagnosis occurs, then we have a chance to change the course of the disease," said Dr. Jorge Barrio, of the David Geffen School of Medicine at UCLA.
Alzheimer's is a disease that slowly destroys someone's ability to reason, remember and communicate.
In this video provided by UCLA, scientists injected study patients with a chemical molecule that attaches to abnormal brain proteins. Then, doctors use pet scanning technology to actually see problems in the brain that could lead to memory loss in the years to come.
