MRI report for migraine says minimal microvascular changes. What does it mean?

Hello doctor,

I am 52 years old and had an magnetic resonance imaging (MRI) for worsening migraines for the last six months. I have had migraines for 31 years. The finding was a few foci of T2 and 3 mm T2 prolongation within the left frontal subcortical white matter. No associated restricted diffusion or abnormal enhancement. No additional parenchymal signal abnormality. The ventricles and midline structures are of normal appearance. Impression or conclusion: Minimal left frontal chronic microvascular ischemic changes. No findings of an acute intracranial process or abnormal enhancement. What does all this mean? My neurologist said to take seizure medicine for the migraines and my brain is fine. Currently, I am taking 12.5 mg of Amitriptyline every day and Sumatriptan when needed.

Thank you doctor,

I am not taking the seizure medicine. I am going through perimenopause, so I think that is what is making them worse. My migraine starts very fast now, usually on right side of head over eyebrow. I have to take 100 mg of Sumatriptan and six Tylenol to stop. I used to have two in a month, and last month had 13. How is the magnetic resonance imaging (MRI) normal? Do many 52 year olds have the same findings? Does it mean I have had small strokes on the left side, and something is wrong with white matter?
