Blood amyloid-β oligomerization associated with neurodegeneration of Alzheimer's disease.

ABSTRACT:

Introduction

Oligomeric amyloid-ß is a major toxic species associated with Alzheimer's disease pathogenesis. Methods used to measure oligomeric amyloid-β in the blood have increased in number in recent years. The Multimer Detection System-Oligomeric Amyloid-β (MDS-OAβ) is a specific method to measure oligomerization tendencies in the blood. The objective of this study was to determine the association between amyloid-ß oligomerization in the plasma and structural changes of the brain.

Methods

We studied 162 subjects composed of 92 community-based normal healthy subjects, 17 with subjective cognitive decline, 14 with mild cognitive impairment and 39 with Alzheimer's disease dementia. All subjects underwent MDS-OAβ and three-dimensional T1 magnetic resonance imaging. To determi
