choice of anti seizure meds

A relative had a syncope episode two months ago - skull fracture and severe head trauma.  recovering fine.  Neurologist is determined that it was caused by a seizure even though hospital neurologist and neuro=surgeon felt there were no clues to determine cause.
Neurologist choice of AEM is keppra even though cost is prohibitive = $15.+ plus per day, not covered by his insurance.
Neurologist keeps repeat EEG, would the TTT with EEG or a holter monitor be a choice.?

The medication Keppra was perscribed because it fits the criteria for treating  certain types of seizures. You failed to report if the medication was working.  The repeat EEg's are to see the progress of the medication, a holter monitor is used for the heart and the only other option would be a long term ambulatory EEg. These are hard to find in many areas. It hardly seems necessary if the neurologist if doing serial EEg's.  It would not show anything different. If the medication isn't working then the neurologist should be told and a medication adjustment can be made. Keppra is the  one of the newest medications available and very highly thought of, despite the cost.
