Photo micrographs demonstrating the types and semi-quantitative scoring of cerebral amyloid angiopathy (CAA). a Cortical CAA, b leptomeningeal CAA, and c capillary CAA. For this study the Olichney scoring system (41) was used and comprises of 4 grades d Olichney 1 A trace to scattered positivity in leptomeningeal or cortical vessels, e Olichney 2 —some cortical or leptomeningeal vessels circumferentially affected, f Olichney 3 A widespread circumferential CAA, and g Olichney 4— widespread circumferential CAA, with dyshoric changes surrounding the vessel. Scale bar represents 200 μm
