Thank you so much for your answer. I don't see the Dr. For several days yet.
Hi!
It is difficult to comment on the exact nature of the hyper-intensities or white regions. However, the three important causes are dilatation of perivascular spaces, demyelination and reduced blood supply. Scattered foci of increased T2/Flair signals indicate small vessel ischemic disease or changes of brain blood vessels. These changes are seen in multiple sclerosis, Alzheimer's or Wilson's Disease, migraine headaches, diabetes, high blood pressure and high cholesterol. Though they are of no immediate threat, all these causes, and the presence of ischemic changes can be a risk factor for future stroke. Hence, prevention methods should include a healthy lifestyle, and a combination of diet, exercise, and medicines. Please discuss with your treating doctors. If you have migraines and a demyelinating disease then these changes are expected. Take care!
