Phases of Aβ-deposition in the human brain and its relevance for the development of AD

Abstract

Abeta-deposition in the entire brain follows a distinct sequence in which the regions are hierarchically involved. Abeta-deposition, thereby, expands anterogradely into regions that receive neuronal projections from regions already exhibiting Abeta. There are also indications that clinically proven AD cases with full-blown beta-amyloidosis may be preceded in early stages by nondemented cases exhibiting AD-related Abeta pathology.
