Alzheimer’s may begin with a silent drop in brain blood flow
Keck School of Medicine of USC researchers report that subtle drops in brain blood flow and oxygen use closely track amyloid plaques and memory-related atrophy, suggesting cerebrovascular dysfunction appears early in Alzheimer’s disease; authors propose that simple, noninvasive vascular imaging could help detect risk before clinical symptoms.
Why it mattersUSC study links cerebrovascular decline to amyloid and atrophy, prompting earlier vascular MRI screening.
