I had Polio when I was a young child; I am now 78 years old and had a hemorrhagic stroke about 15 months ago. The Neurologist at the local hospital said they had no idea what caused the brain bleed ; so I consulted a Neurological Team (consisting of a Neurologist, a Vascular Specialist & a Neurological Surgeon) at Shands Hospital in Gainesville, Florida. This is the highly respected teaching hospital for the University of Florida. The neurologist diagnosed my problem as CAA. I have fallen 8 times and injured my head 3 times (one time resulting in 7 staples to close the wound in the back of my head & subdural hematoma (sp), and another time 5 stitches in my forehead). Each of the 8 times I fell I required assistance in getting to an upright position, something that was unknown to me before my stroke of 15 months ago. Before the stroke I was described by wife as disgustingly healthy , a term with which my personal physician also agreed. I would appreciate your answer to the similarities & differences between CAA, Post Polio Syndrome & Parkinson Disease. With Kind Regards Robert Moger
