(University of Southern California) Older adults with elevated levels of brain-clogging plaques -- but otherwise normal cognition -- experience faster mental decline suggestive of Alzheimer's disease. This study presents the toxic, sticky amyloid protein as part of Alzheimer's disease -- the earliest precursor before symptoms arise. If Alzheimer's prevalence estimates were to include this "preclinical stage" before symptoms arise, the number of those affected would more than double from the current estimate of 5.4 million Americans, the study stated.
