In real terms there is no permanent cure with the medicine. However, more than 2/3rd of the patient usually get seizure
free with medication alone. In rest, if a surgically correctable lesion is identified, the cure rate is as high as up to 80%. Please go to the local neurologist
with special interest in epilepsy
who would guide you to few investigations like
SPECT/PET scan to identify the focus.
So please go for them, lots of hopes are there.
