Permanent memory loss after seizures?

My main question is can a seizure, series of seizures, or a seizure disorder cause permanent short term memory loss?

I am a 29 year old white male.  I had 3 spells of seizures and blacking out that put put me in the hospital on 3 seperate occasions about 2 years ago.  On one of those occassions, I spent a week in ICU having over 30 seizures in one day.  I had numerous test run and they found electrical activity proving seizures but not in all cases.  They ruled out epilepsy and other seizure related disorders.  I was finally diagnosed with post traumatic stress disorder and began treatment with counseling and medication such as lamictal, anti-deppressants and anti-anxiety meds.  I have been seizure free and doing very well for over a year now with one exception.  Since that whole ordeal, I have noticed a huge change in my short term memory abilities.  I have a very difficult time remembering things that looked at or did any where from 2 minutes ago to 4 hours ago.  I literally have to force myself to remember very simple things by constantly going over them in my head until it becomes locked.  I know this sounds silly, but a fine example is directions.  Most people can be told "turn left on Main St, then right on North Ave" and they can remember it.  After all, those are very simple and clear directions.  With me, I have to say them silently to myself over and over for at least 10-15 minutes or i cannot remember.  Eventually things come back to me. But the lack of maintaining short term memory is really starting to interfere with my life.  Can seizures damage things that could cause memory loss such as this?

I'm having a terrible time with short term memory recall after what I experienced as a series of seizures. My EKG and MRI didn't show anything, and I was sent spiraling into what I know now as bipolar cycling so it's hard to know where the problems are due to, but i've been experiencing the exact symptoms you describe. I am also dealing with difficulties with finding the right words sometimes as well. I was very aphasic for weeks afterwards too, and my docs aren't very helpful when I ask about all this. It *****, and I'm trying to cope but it is so pervasive that it is hard to just ignore.

Anyway, you're not alone. If you figure this out any better, shoot me an email at edisto64 (at) hotmail *******. Take care, brother.
