I68.0: Cerebral amyloid angiopathy

The brain controls the body’s critical functions such as breathing, blood pressure and heartbeat. The brain is where thinking takes place, actions are planned and movements are coordinated. To carry out all these tasks, the brain needs enough oxygen. This oxygen gets into the brain through the blood vessels.

If the blood vessels are damaged, the supply of oxygen to the brain can deteriorate. This results in the brain no longer being able to carry out its tasks properly. Then you might get bad headaches or be unable to control your movements properly. A blood vessel may also get blocked or tear. This can result in a stroke. That can cause various symptoms. For example, you may no longer be able to move some muscles properly, or to speak properly.

In the blood vessels in your head, proteins have been deposited that should not be there. This may cause the blood vessels that are affected to become narrower than normal. At the same time, the wall of the blood vessels may also become more fragile.
