Abstract

Sporadic cerebral amyloid angiopathy is a small vessel disorder defined pathologically by progressive amyloid deposition in the walls of cortical and leptomeningeal vessels resulting from disruption of a complex balance between production, circulation, and clearance of amyloid-β peptide (Aβ) in the brain. Cerebral amyloid angiopathy is a major cause of lobar symptomatic intracerebral hemorrhage, transient focal neurologic episodes, and a key contributor to vascular cognitive impairment. The mechanisms and consequences of amyloid-β deposition at the pathological level and its neuroimaging manifestations, clinical consequences, and implications for patient care are addressed in this review.
