Toward a comprehensive theory for Alzheimer's disease. Hypothesis: Alzheimer's disease is caused by the cerebral accumulation and cytotoxicity of amyloid beta-protein

Abstract

A central challenge of research on Alzheimer's disease (AD) is to assemble the enormous body of scientific observations about the disorder, some of them seemingly in conflict with others, into a coherent and credible mechanism of pathogenesis. In this article, I attempt to synthesize the disparate findings on AD into a unified sequence that essentially begins with alterations in the production or clearance of the amyloid beta-protein (A beta). Mounting evidence from many laboratories supports an A beta accumulation in limbic and association cortices as the fundamental initiator of the disease, with attendant therapeutic implications.
