Damage to brain associated with Alzheimer's occurs up to 20 years before symptoms start showing
Poor sleep among older people suggests that it's an indication of increased risk for Alzheimer's
The researchers reviewed data from more than 150 research articles
Clinical trials are expected to begin in the next few years, said researchers
Of particular note was that these brain abnormalities were found in a relatively young group
