CAA facts:

  • CAA is the third leading cause of stroke and is not well publicized.

  • CAA is defined by a type of protein deposit in the wall of blood vessels in the brain.

  • CAA is actually a common process in aging and usually harmless.

  • In some people with CAA, the protein deposits cause the blood vessel walls to crack, in which case blood can leak out and damage the brain.

  • The damage from this process is called a bleeding (or hemorrhagic) stroke.
