Imaging study links key genetic risk for Alzheimer's disease to myelin breakdown

...f the UCLA Alzheimer Disease Research Center. "The quality of the brain's connections is key to its speed, bandwidth, fidelity and overall on-line capability."

Efficiency, not more doctors, is the prescription for aging population

... "We believe that, in fact, less is more, and that quality of care, rather than quantity, is the critical factor" The research focuses on the management of severe chronic illness because it is the area where health care resources are most heavily used--about half of Medicare's budget goes to the care of chr...
