Cognitive issues following cyberknife for pituitary adenoma

I had cyberknife 7 years ago for a pituitary adenoma which resulted in acromegaly. I have noticed increasing cognitive issues esp. Problems with Facial recognition which seem to be increasing over the past year. Could this be a result of the cyberknife treatment? Interestingly it took approximately 6 years for my growth hormone to reduce to a normal level after cyberknife treatment.

It could be a problem from treatment, although we have not really seen that. It was a common problem in the days when most of the treatment went through the temporal lobes. There are, of course, multiple other possibilities. I would suggest seeing a good neurologist and a good endocrinologist if you are not already doing so.

Due to radiation therapy, may happen that it has damaged the remaining normal pituitary. Due to that you will lose normal pituitary function over time. You should take treatment with hormones.

Ignore the above from Austin - it is stupid To all on these forums: When you see these postings that have a link to Cancer Support etc, you are being trolled. A series of cancer centers in Nevada is trying to obtain patients with posts that appear to be real but are just an excuse to put in a link to their site. My guess is that if they are that hard up for patients, their quality must be poor, although I have no real way of knowing. Certainly, good centers don't engage in this sort of activity.

Dear Austin - you should also develop at least a passing acquaintance with proper English grammar
