Abstract
The subject of iron and iron regulation in the body has recently come under scrutiny as neurobiologists attempt to find underlying causes for neurodegenerative diseases such as Alzheimers, Parkinsons, and Huntington s and syndromes such as Hallervorden-Spatz. Each of these disorders includes iron accumulation in affected regions of the brain as a part of their pathogenic profile. Although it has long been known that iron is essential for life, what is not clear is how iron levels are maintained in a healthy nervous system and how these levels can become altered in disease states. The chapter will begin by addressing the normal role of iron in the body, because attempts for therapeutic intervention may begin at the level of iron absorption in the gut. In addition, understanding iron absorption by the gut may help to elucidate the mechanism by which iron is transported across the blood-brain-barrier (BBB). The remainder of the chapter will focus on the proposed role iron may play in Alzheimer s disease (AD) pathogenesis. The chapter will conclude with theories as to how known pathological mechanisms involved in AD may be controlled or at least influenced by a loss of iron regulation in the brain.
