I was diagnosed in 2010 wit Afib. I was put on an adult aspirin once daily. Then in January2015 I had a brain hemmorage stroke and was diagnosed with cerebral amyloid Angiopathy. I can no longer take any blood thinners of any kind, leaving me in quite a tight spot. I am 67 years old. I understand your concerns and I too have been considering seeing someone at Mayo who is very familiar with CAA.
