I just had an MRI due to having migraines for a week - not like me. I am 67 years old, but am diabetic from an acute case of pancreatitis, take high blood pressure pills and cholestral meds. My blood work was good low blood pressure from meds. My MRI said:

"Brain parenchyma: Numerous small foci and some patchy confluent areas of hyperintense T2/FLAIR signal are present thout the cerebral hemispheric white matter with relative sparing of the temporal lobes and infratentorial brain panchenchyma in a pattern most consistent with chronic microvascular ischemia. There has been significant interval increase in the number of these lesions since the previous examination (which was years ago when they increased my blood pressure meds). The brain parenchyma is otherwise grossly unremarkable. There is no abnormal parenchymal enhancement. Hemorrhage: There is no evidence of intraparenchymal or extra-axial hemorrhage. Ventricles: Ventricles, sulci and cisterns are normal for age without evident of mass effect or shift. Herniation: None.
What is going on and what would be treatment of this? My father died of a heart attack at 72 years of age, but my mother lived til she was 94. Could this be a problem with my heart? I have an irregular heart beat like both my parents. I am a retired teacher, but still substitute often. My brother (an opthemalogist) in his 50's just had open heart surgery to replace a valve.
