According to the passage, the reason for the characteristic decline in mental capacity occurring in those with Alzheimer's----.
An antibiotic that removes metals from the brain is
emerging as a prime candidate for treating
Alzheimer's. This boosts a controversial theory that
blames the accumulation of metals, rather than the
formation of insoluble plaques, for the disease's
characteristic mental deterioration. The antibiotic,
clioquinol, binds to copper and zinc and is small
enough to get into the brain. It is no longer
manufactured but was last used in the 1970s to
treat intestinal infections. Now, in various medical
schools, efforts are being made to resurrect the
drug to treat Alzheimer's.
