I have been taking keppra for a year now. My current dose is 3,000mg of extended release every day. I have had anywhere from mild seizues to a Grand mal seizure which nearly took my life. I also have advanced alzheimers. I have not had one seizure since starting keppra. My ability to function on my own again is all thanks to keppra. For me it has been a miracle drug ( with side effects). I don't know how much time the drug will buy me but I will enjoy the time I have been given back.
