Copper Identified as Culprit in Alzheimer's Disease

Monday, August 19, 2013

Copper appears to be one of the main environmental factors that trigger the onset and enhance the progression of Alzheimer's disease by preventing the clearance and accelerating the accumulation of toxic proteins in the brain. That is the conclusion of a study appearing today in the journal Proceedings of the National Academy of Sciences.

It is clear that, over time, copper's cumulative effect is to impair the systems by which amyloid beta is removed from the brain, said Rashid Deane, Ph.D., a research professor in the University of Rochester Medical Center Department of Neurosurgery, member of the Center for Translational Neuromedicine, and the lead author of the study. This impairment is one of the key factors that cause the protein to accumulate in the brain and form the plaques that are the hallmark of Alzheimer's disease.
