Selenium is an essential micronutrient to mammals and plays its role through selenoproteins characterized by the presence of the 21st amino acid selenocysteine. Although these proteins are of low abundance in the brain, they participate in different mechanisms required for brain homeostasis, such as neutralization of reactive oxygen species and modulation of Ca2+ channels and mitochondrial function. Selenium has been identified as playing a role against Alzheimer's disease by minimizing amyloid β aggregation, hyperphosphorylation of tau protein, and preventing neuronal death. This chapter discusses the current literature investigating how selenium may be involved in Alzheimer's disease pathogenesis.
