My wife and personality change

My wife has had a car accident when she was 2 years of age. She suffered brain damage and als was in a coma for about 14 days. Now she is 45. I live with her 20 years now and in the beginning of my relationship with her i noticed that she suffered minor seizures when she was tensr or stressed. It were sz of about 1 or 2 sec. She took very little medication occasionally for it. Only if she had to do some stressfull thing, like talking in public. I dont know the name of the medication, but it helped her for those couple of hours. She lived a normal and happy live all those years, until about 5 years ago. In a stressed situation at home (tired and doing something stressfull (filling in papers)) she got a big attack/sz. It was her first and only big attack/sz ever. She had to go to hospital for 1 night, and it seems she recovered fully after it. She was put on depakinr after it. That seems to work for her. Untill about 15months ago. She suffered some annoying side-affects of the depakine so she asked her doctor for other medication. Her doc asked her to do some brainresearch so he can prescribe the right dosis of new medication. This research of my wifes brain showed that she suffers now every 7 minutes minor seizures, and there is a huge possibilitt she will get an big attack/sz again if not on good medication. My wife told me this was more confronting her then when she heard she was diagnosed with cancer some years ago (fully recovered). Her doc prescribed levetiracetam also known as Keppra because it should have less side-effects. After starting taking Keppra i recognised (as her husband (very close to her)) a change of her personality. Soon after taking Keppra she was full of rage against me. Sometimes out of the blue she was extremely angry at me. Simple discussions where/are difficult. She even threw a glass of wine against the wall out of sudden rage. I mentioned then to her that i didnt see herself anymore. She is since then blaming me of all our relation-problems. Broke up our marriage several times (in words). She says she was not taken serious and respected for years, even not worth living perhaps etc etc. At the same time, i was suffering a minor burn-out and ended loosing my job around that period. All the years before all this happened, i tried to be a loving and caring husband. As i still try now. In an effort of knowing what was going on in her mind, i started some research about keppra etc. When she found out i was doing that she was so angry at me......she felt disrespected etc. In an attempt to try to control our situation i asked her if i could see her doctor. She agreed after long argeuing, and under protest. Finally: no less keppra because her rage could also be out of relationship-problems. This was leaving me desperate. In the months on my wife suffered some more side-effects like being very tense, depressed feelings, very tired, easily aggitated (towards me especially, and not the kids), crying very easily. After a discussion with her doctor she started taking less keppra. Then after a while she told me she felt less tense overall and agreed slowly it could be the Keppra. In the meanwhile our marriage is nearly over, because she found another guy who understands her MUCH better and she fell in love with him. She cheated on me twice with him. This is something she would never ever do, being herself. She even agrees on that and says she cant explain why she does it, because she hates people who do those things (she even wrote this down to me). But nearly all of our relationship problems she blames on me. I still tryaronstayystrongybecauseecasee a kind of personality change since she started taking Keppra. Since ently i nearly command her to stop the Keppra right away (knowing it is a difficult way to change medication again). She agreed to it and is trying to talk to her doctor now to take het of Keppra. Does anyone recognise her behaviour in relation to epilepsy, seizures or keppra / levetiracetam? Or could it just be me who is getting crazy?
