Cerebral amyloid angiopathy is a neurological condition in which proteins called amyloid build up on the walls of the arteries in the brain. The condition increases the risk of hemorrhagic stroke and dementia.

Amyloidosis - cerebral; CAA

The cause of cerebral amyloid angiopathy is unknown. Persons with this condition have deposits of amyloid protein in the walls of the brain arteries. The protein is usually not deposited anywhere else in the body.

The major risk factor is increasing age. The rate of the condition is much greater in those older than 60.
