neurology, round 2

Our second meeting with the neurologist was less overwhelming that the first, mostly because we knew more or less what to expect to hear. That's not entirely accurate - I didn't know whether to expect to hear that the white matter lesions had gotten worse. I did my best to prepare to hear that yes, they had gotten worse, though.

The news is basically good: nothing has changed. Iris still has white matter lesions, but the damage hasn't progressed. And the vessels all appear about the same size -- they haven't narrowed. Patients with the ACTA2.r179 mutation have dilated internal carotid arteries and narrower middle cerebral arteries. Her middle cerebral arteries do not look paricularly narrow at this point.

One piece of information I had forgotten, though has been mentioned in the past by various specialists, is that the ACTA2.r179 mutation results in the overproduction of smooth muscle cells. So, over time, the space for blood to flow narrows as the vessel walls become thicker. And at that point the neurologist would tell us that a major stroke is imminent and that it's time for surgical intervention.

Barring any TIA's or other neurological events, I'm hoping to push the next MRI to a year out. It seems that the other ACTA2.r179 folks have MRIs about every 12-24 months...not more frequently than that unless there are major indicators requiring it.

So, overall, good. (Amazing how your bar of what qualifies as "good" changes. We adapt.)
