Cerebral amyloid angiopathy in a patient with Alzheimer disease (photomicrograph)

Cerebral amyloid angiopathy (and senile plaques with amyloid cores) can be demonstrated using Congo red staining with polarization microscopy. Micrograph shows a Congo red-stained section from the brain of a patient with severe Alzheimer disease-related cerebral amyloid angiopathy. (Contributed by Dr. Jeffrey L Saver.)
