MRI Scans Reveal Brain Changes in People at Genetic Risk for Alzheimer's

ScienceDaily for December 30, 2010 reported on brain-changes that indicate a susceptibility to
Alzheimer's and Dementia.

"We looked at a group of structures in the brain that make up what's called the default mode network," says lead author Yvette I. Sheline, MD. "In particular, we are interested in a part of the brain called the precuneus, which may be important in Alzheimer's disease and in pre-Alzheimer's because it is one of the first regions to develop amyloid deposits. Another factor is that when you look at all of the structural and functional connections in the brain, the most connected structure is the precuneus. It links many other key brain structures together."
