Alternate Names : Amyloidosis – cerebral, CAA
Cerebral amyloid angiopathy is a neurological condition in which amyloid protein builds up on the walls of the arteries in the brain. The condition increases one’s risk of hemorrhagic stroke.
Overview, Causes, & Risk Factors
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.

Amyloidosis on the fingers
Amyloidosis refers to the extracellular deposition of a protein called amyloid. This protein deposition can affect multiple organs. The deposition of amyloid may be a by-product of normal aging, or may occur with several other conditions. In this picture, we see how amyloidosis can affect the skin as nodular deposits on the fingers.
Arteries of the brain
The internal carotid arteries and the vertebral arteries supply blood to the brain.
