What is CAA?

Cerebral amyloid angiopathy (CAA) is a condition where a protein called amyloid-beta builds up in the small blood vessels of the brain, particularly in older people. This can lead to bleeding in the brain which causes hemorrhagic strokes. CAA often happens alongside Alzheimer's disease and can worsen problems with memory and thinking. It seems that the issue lies more in the brain's ability to clear this protein rather than in its production. Unfortunately, there aren't any specific treatments for CAA yet. Right now, doctors focus on managing blood pressure to help reduce the risk of bleeding in the brain.

What is Clearance?

The brain needs a steady flow of nutrients and oxygen to work properly, just like any other part of the body. It also needs to get rid of waste products that build up as it works. This happens through something called the glymphatic system, which includes a network of channels around blood vessels that help clear out waste from the brain's fluid. Think of it like a cleaning crew that keeps the brain tidy.
