epilepsy
"I had a heart attack and had a stent which led to a stroke and the need for brain surgery.  Miraculously, I was saved by a young neurological surgeon.  Seizures followed but the recovery the first 3 months on a lot of different medication made the outlook positive.  Medication was lowered and I started experiencing what we feared were TIAs but was finally diagnosed as a form of epilepsy.  The first medications did not work well until I have been on Levetiractam for 6 months and everything has improved a lot during that period including memory and mood.  I do have the sleepiness at night but not a problem."
