Hello, this is Dr. David. I am reviewing your question now and will be with you momentarily.
why did you have the brain MRI scan
you most likely have had that basilar aneurysm for years or decades before it was detected now.
chance of the basilar aneurysm progressing to dementia is so super low, less than 1% chance.
most likely it will stay stable and not change for years and you will die from other causes. how big is the aneurysm?
