### input:
I had an MRI which showed stable microvascular ischemia white matter changes without demylinization. I am a 34 year old, 284 lb woman with a hx of migraines with aura. The MRI was done because the aura prior to a migraine changed from the electrical current type to seeing tracers. For the past few months I have had chronic headaches, not just the hormonal migraines I typically see. I take Fioricet for my headaches because nothing else has seemed to work. I do not have high blood pressure or cholesterol issues despite being morbidly obese. I do not have pre-diabetes or other blood sugar issues. My mother has a hx of TIA s, diagnosed when she was 40. I am still waiting for a neuro appt because the neurologist wants to review all of my medical files before setting the appointment. 1. How does the radiologist know the changes are stable when I have never had these show up on an MRI before? 2. Could this be migraine related as opposed to TIA s? 3. What can I do to prevent the changes from becoming chronic?

### output:

Hi, Regarding your concern, I would explain that these MRI findings could be related to the migraine attacks, which is known to lead to microvascular dysfunction and brain white matter changes.  The fact that they are stable is related to the fact that they are not enhanced on DWI images (a specific MRI technique), which means that they are older than three months.  The only thing to prevent those changes would be daily baby aspirin and a close monitoring of your blood pressure, fasting glucose and blood lipid profile. Hope I have answered your query. Let me know if I can assist you further.
