Abstract

Abnormalities in the homeostasis of brain metals in Alzheimer's disease (AD) can contribute to set up environmental conditions where β-amyloid toxicity and deposition are promoted within areas at risk. Recent studies in man have described possible implications of copper in the AD pathogenesis. In particular, evidence collected in our laboratory in the past six years shows that abnormalities in copper distribution originating from blood stream variations correlate with functional and structural brain deficits in AD. Despite these works supporting a damaging role of copper, new studies hypothesize a protective role. In fact, some recent studies have shown that a decrease of serum copper in man correlates with a worse neuropsychological performance. However, this apparent discrepancy concerns the absolute serum copper levels and can be overcome by considering the fraction of non-ceruloplasmin-copper (NCC).
