Cerebral amyloid angiopathy (CAA) is characterized by the deposition of congophilic material in the vessels of the cortex and leptomeninges. Although CAA most commonly appears in a sporadic form associated with aging, several familial forms of CAA reported to date. Hereditary cystatin C amyloid angiopathy (HCCAA) is a rare, fatal amyloid disease in young people in Iceland caused by a mutation in cystatin C, which is an inhibitor of several cysteine proteinases. It has also been reported that mutations in APP are linked to CAA.
