hi my son is 28 yrs old, hes had 2 seizures at work last month and last week in my home he had a seizure then an hour later had another,he spent night in hospital and had an mri which showed a cyst on left side of brain,he was put on seizure medicine but does not have insurance for more testing to be done,will this medicine help the seizures or will he continue to have more seizures on the meds because of cyst?? is it major surgery to have it removed? thank you,deb russell
