Does Gleevec cause memory loss?

I have not experienced any memory loss that I can associate with Gleevec/Imatinib nor have I heard about it, thankfully. However, I am 70 and I’ve notice that I lose words once in a while. Additionally, this is my third cancer (and I have other medical problems) so I do consider myself under stress which I believe I manage pretty well. That said, I believe stress can cause all sorts of side issues and perhaps if you are experiencing some memory loss, it can be the stress of the diagnosis.
