Attentional ERPs Distinguish Aging and Early Alzheimer ’s Dementia

The early detection of Alzheimer ’s disease requires our distinguishing it from cognitive aging. Here we test whether spatial attentional changes might support that distinction. We engaged young (YN) and older (ON) normals, and patients with early Alzheimer’s dementia (EAD) in an attentionally cued, self-movement heading discri mination task while we recorded push-button RTs and ERPs. YNs and ONs show the behavioral effects of attentional shifts from the cue to the target, whereas EADs did not (p
