A new study has uncovered how Alzheimer's spreads in the brain; the findings may mean it's possible to stop the disease.
Researchers have discovered that a distorted protein called "tau" that's found in the area of the brain where memories are created, spreads to other areas of the brain, cell by cell. If scientists can stop that from progressing, there's hope researchers can figure out a way to stop the disease.
Health experts said this is good news for Alzheimer's patients and their caretakers.
"It's so exciting, and certainly a lot has to be done, but for us at the association and the things that we're doing right now, we're providing supportive services. This means so much to families who feel so isolated day-by-day, with this disease,” said Laura Holly-Dierbach, from the Alzheimer's Association.
About 5.5 million Americans suffer from Alzheimer's disease.
