I recently had an MRI done w & w/ out contrast of the brain as I was complaining of some blurred vision turns out they discovered 2 cerebral infracts. My Dr said for a lack of a better word that i had to very minor strokes & that I was OK now as I passed all the neurological tests in his office. My question is this finding make a risk to have surgery ? I'm 41 yrs old my other health signs all are f=good i.e blood pressure , no diabetes & cholesterol.
