seizures
"I had my first seizure at age 56.  Reason still unknown.  The doctors had a terrible time getting them under control.  My husband and I didn't know what was going on.  Zonisamide gave me back my life!  I had some side effects at first, but they passed after about a month.  The side effects I had were drowsiness and a feeling of confusion....but all of this passed.  Then things slowly got back to normal.  Now I have been on the Zonisamide for 3 years and have been seizure free...completely....for 2 years.  This is a good med.  It saved me."
