According to Health Day News, copper may be contributing to Alzheimer's disease. "Copper appears to be one of the main environmental factors that cause Alzheimer's disease and contribute to its progression, according to a study of mice and, in some phases, human brain cells.
The common metal prevents the clearance and accelerates the accumulation of toxic proteins in the brain, the researchers said.
"It is clear that, over time, copper's cumulative effect is to impair the systems by which amyloid beta is removed from the brain," study author Rashid Deane, a research professor in the department of neurosurgery at the University of Rochester Medical Center, said in a medical center news release.
"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," Deane said." read more
