A new study now shows that the size of a person's brain can indicate risk for getting Alzheimer's disease..

The study found that the elderly were more likely to develop symptoms of early Alzheimer's if certain regions of their brain were small.

Researchers studied the brain scans of 159 people.

Over the course of three years, the individuals were given tests to measure memory, problem solving and attention span.

Twelve percent were classified as high risk of developing early dementia based on MRI results and test scores..
