Hi do you get migraine and does anyone in your family have ever had migraine or taken strokes. My family and I have white matter on the brain, migraines and strokes, we are diagnosed with Cadasil, please get back to me to discuss
You are a strong lady and as the MRI had revealed so much the clinician wants to see the progression after 6 months.
In a brain disease the risk of operation is compared to the quality of life you are leading, as you only passed out once he wants to wait for 6 months and if you do not have any symptoms or no growth etc he will not put you into surgery and other difficult treatment modules.
So you can go ahead to Mayo Clinic and take care!
