Intra and inter‐network connectivity in the olfactory network and default mode network across the Alzheimer's disease spectrum: An analysis of COMPASS‐ND cognitive and imaging data

Abstract

Background: Olfactory dysfunction is a prevalent and early symptom of Alzheimer's disease (AD), often preceding the core memory impairment features of AD. Moreover, brain regions integral to olfactory processing are implicated in the early AD pathophysiology.
