I’m new to this all so back in December my son age 13 started having seizures in the bath and a few outside of bath so about 3/4 weekly. to cut the story short his eeg mri have all come back normal but they think it’s focal epilepsy so they have put him on keppra he’s just about to increase his dose tomorrow we have been seizure free since he started 2 weeks ago but had one yesterday is this normal to still have seizures until he gets up to his biggest dose
