Cerebral amyloid angiopathy: a cross-sectional study in a single center in Northeastern Brazil.

Background: Cerebral amyloid angiopathy (CAA) is a cerebrovascular disorder caused by progressive deposition of β-amyloid peptides in the walls of small and medium-sized cortical and leptomeningeal vessels. Until today, the prevalence of CAA is unknown in our region.
