CAA (Cerebral amyloid angiopathy)

Cerebral amyloid angiopathy (CAA) is a condition where abnormal proteins called amyloid deposits build up in the walls of blood vessels in the brain. This weakens the blood vessels, increasing the risk of bleeding, small strokes, and brain damage. CAA often occurs with aging and is linked to Alzheimer’s disease. Symptoms may include sudden neurological changes, memory problems, or headaches. Diagnosis involves brain imaging, and there’s no cure, but managing risk factors can help reduce complications. CAA highlights how protein buildup can affect blood vessel health and brain function.
