Copper may be a trigger of Alzheimer's disease

Copper, which is found in anything from drinking water to red meats, may be an environmental trigger of Alzheimer’s disease, according to a new study.

It is clear that, over time, copper impairs the systems through which amyloid beta is removed from the brain, said Rashid Deane, a research professor in the University of Rochester Medical Center  Department of Neurosurgery, member of the Center for Translational Neuromedicine, and lead author of the study.  This causes the protein "to accumulate in the brain and form the plaques that are the hallmark of Alzheimer's disease."
