Can Pre Clamptic Fits During Pregnancy Effect Emotions, Memory Later?

I had pre-eclampsia and fitted quite badly when i gave birth to my twin boys over 13 years ago. I had a CT scan recently and i appear to have an area of my brain that has been starved of oxygen at some point. Could the pre-clamptic fits caused this and what effect does that have on me e.g. will it affect emotions, memory etc? I also have discovered from CT scan that i have too much fluid around my brain, i have been referred urgently to a Neurologist.
