I too have white matter and small vessel disease.I have started taking statins,not because I have high cholesterol,but because there is evidence that lowering the LDL can slow progression.My BP is normal,so no need to treat.I am scheduled for a cardiac stress test,because this also can affect the heart,But the rythmn of my heart is normal.My advice,in view of the symptoms you are having,is to be seen by a neurologist.A vascular neurologist would be best,if you can manage that.BTW I had 2 radiologists view my MRI scan.Terms like,"mild" "moderate" "severe" are subjective.Another opinion of the scan itself might also be of use to put focus on the degree of white matter there is.You can write me anytime.I don't know if its OK on this forum to give out personal emails. *** I live in Montreal Canada.
