Alzheimer’s Disease: Errors in Gene Expression

Abstract

Hypotheses concerning the etiology of Alzheimer’s disease are numerous but perhaps two of the most probable involve either an unconventional infectious agent of the scrapie, Creutzfeldt-Jakob family or an error in gene expression. Strong circumstantial evidence supports both hypotheses; however, definitive evidence will require an extensive understanding of the molecular biology of this common cause of senile and presenile dementia.
