Hello, my recovery was remarkably quick. My worst symptom was severe short-term memory disruption, due to the cyst pressure on a nerve-fiber bundle component running out of the hippocampus called the fornix. This apparently plays an important role in memory formation. Once the pressure was removed, the change in my memory test scores was enormous. This happened within days. It was quite remarkable. Of course, the headaches etc. were also relieved. I have had some backsliding on memory function, which is a bit of a mystery as the cyst is basically gone (fenestrated, as they call it), but it is still way better than at the height of the problem. If nothing else, I can say this has been educational...
