I had an MRI done about five years ago and it showed some white matter changes. The latest MRI last week showed the white spots had increased both in number and in size. It also showed what may be an old infarction in the right hemisphere. The radiologist also noted in the "Impressions" section "Cerebral Atrophy." My primary care doc said it was nothing to worry about, that we just needed to keep my blood pressure and blood sugars (I'm diabetic) under control. Well, my untrained mind is worried.
