question: I had an MRI recently becasue of a thalamic glioma.  That remains stable but I was also told I had microvascular ischemic disease.  I have never had high blood pressure or diabetes.  Nor do I have MS.  I year ago I was in intensive care for a "brain Bleed" which later after more MRI's they discoved the tumor.I do not understand the this ischemic disease.  What can I do to prevent a full blown stroke?Thank  you.
