Alzheimer's: brains change before symptoms show

Researchers from Harvard Medical School have found that people's brains can start to go bad ways even before they have any symptoms of Alzheimer's disease.

Using brain scans the researchers found that a significant number of older people without dementia showed amyloid deposition and abnormal neural activity in important areas of the brain network thought to be involved in memory.
