I had a series of MRI's last May(23) and the report revealed I had an aplastic A1 segment of the left ACA. I found out that the reason why the A1 segment of the ACA is so commonly involved in MS is not fully understood. However, it is thought to be due to the fact that this artery is particularly vulnerable to the inflammatory and demyelinating process that occurs in MS.
Now, I have been to 3 neurologists so far, and no one has been able to put a finger on what's going on. You'd think 12 years of post education would have something to show for it. My wife and I are frustrated, as we don't know WHAT'S going on. Can anyone here give me more of an idea? Thanks, Carl
