Brain scans of healthy people showed signs of shrinkage in Alzheimer's affected areas nearly a decade before the disease was diagnosed, according to a new study.

Researchers studied two groups of healthy people in their 70s who had brain scans and were followed an average of nine years. Fifty participants remained normal, but 15 developed Alzheimer's disease.

Scientists found that people with the highest amount of shrinkage in specific areas of the brain were more likely to develop Alzheimer's.

The study is in the journal Neurology.
