Oxidative damage to every class of biological macromolecule has been characterized in Alzheimer's disease. Abnormalities in iron and copper metabolism are also being implicated as playing a crucial role in neurodegenerative disease pathogenesis. Metal homeostasis as it pertains to alterations in brain function in neurodegenerative diseases is reviewed here with its relationship to oxidative stress. While there is documented evidence for alterations in transition metal homeostasis, redox-activity, and localization, it is also important to realize that alterations in specific copper- and iron-containing metalloenzymes also contribute to the neurodegenerative process. These changes offer the opportunity to identify pathways where modification of the disease process can offer new routes for clinical efficacy, from gene therapy to use of antioxidant and chelating drugs.
