Intraneuronal A beta Accumulation, Amyloid Plaques, and Synapse Pathology in Alzheimer's Disease
Background: beta-Amyloid (A beta) plaques are a pathological hallmark of Alzheimer's disease (AD) and multiple lines of evidence have linked A beta with AD. However, synapse loss is known as the best pathological correlate of cognitive impairment in AD, and intraneuronal A beta accumulation has been shown to precede plaque pathology. The progression of A beta accumulation to synapse loss and plaqu
