DISCLOSURE: THIS PAGE IS NOT MEANT TO BE A CLINICAL RESOURCE. FOR CLINICAL QUESTIONS ABOUT CAA, PLEASE CONTACT YOUR DOCTOR. Cerebral Amyloid Angiopathy (CAA) is a neurological disease 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 is usually harmless. In some people with severe CAA, however, the protein deposits cause t

he blood vessel walls to crack, in which case blood can leak out and damage the brain. Damage from this process are called brain bleeds, and can either be small (microbleeds) or large (macrobleeds). This page is intended to be a centralized space for individuals living with CAA, their friends, family, and others interested in the disease to share CAA-related news, resources, and to connect with one another. This page is hosted by the Cerebral Amyloid Angiopathy and Hemorrhagic Stroke research group at the Massachusetts General Hospital. Initiated in 1994, the Hemorrhagic Stroke Research Program has become internationally recognized as a leading authority on the causes, diagnosis, and treatment of cerebral amyloid angiopathy.
