Cerebral amyloid angiopathy or congophilic amyloid angiopathy can by visualized in frontal cortical sections using Aβ directed immunohistochemistry (a) or Thioflavin S staining (b) similar to that used to detect senile plaques, and they are believed to contribute independently to the Alzheimer’s disease course. Scale bars are 40 μm
