I had a subarachnoid tumor pressing on the fornix which was fenestrated in summer 2017.

I seemed to make a good recovery, and my badly impinged memory got better. Since then, I have had recurrent memory loss. The doctor things the surgery was successful, so has suggested that I may have a kind of silent epilepsy. He says it might have started from the effect of the tumor. I am going for brainwave scanning tomorrow. The doc also tells me that 1% of people have some form of epilepsy, so nothing too much to worry about.

Does anyone have experience with this kind of quiet epilepsy that mainly damages memory formation?
