@gbiffart Cranial Amyloid Angioplasty I suspect you mean "Cerebral Amyloid Angiopathy" I could not find anything on "Cranial Amyloid Angioplasty", but there is lots on Cerebral Amyloid Angiopathy if you Google it. I say this because it is a part of my Primary Familial Systemic AL Amyloidosis in the cerebral cortex. This runs in my family. Actually, there are a bunch of us that have it. It is an amorphous (without shape) deposit of dead proteins in the brain. It is built up over many years. Usually it starts as a single cell, and it could begin long before birth. Then it divides, and divides again and begins to conquer. By the time one is in their 50's or later, the deposit in the cortex (it is like Alzheimers, but in a different part of the brain) is noticeable on CT. It is a form of Amyloidosis. (see http://www.amyloidosis.org). I leads to dementia, and is always fatal if one lives long enough. This form makes little fibrils, tubes filled with water, which get between the cells of the body, and particularly the cells of the nerves and the artery walls, interrupting the flow of electrical signals. And for @lisalucier, I suspect you might find others under Cerebral Amyloid Angiopathy. There are many centers who deal with this, including Mayo-MN, Brigham and Women's, Stanford, etc. And my own story and situation is posted free at : https://bit.Ly/1w7j4j8 Free, and as accurate as possible.
