White Matter Hyperintensities Linked to Alzheimer's Disease: A new study adds to a growing body of evidence pointing to small-vessel cerebrovascular disease as an important contributor to Alzheimer's disease (AD).
The study shows that increased total white matter hyperintensities (WMHs) as seen on MRI independently predicted AD diagnosis, as did the brain amyloid tracer Pittsburgh compound B (PIB) measured by positron emission tomography (PET).
