Welcome to Connect, @jo1016. Thank you for sharing your son’s history – he’s so young, and I can imagine it must be quite scary and stressful! Oxcarbazepine is in a class of medications called anticonvulsants. It works by decreasing abnormal electrical activity in the brain. You may also appreciate this additional information about Trileptal: https://medlineplus.gov/druginfo/meds/a601245.html

May I ask if your son is ‘aware’ when he has an episode? I read that there are 2 types of focal seizures: simple partial and complex partial seizures. Is this something that he may outgrow with age, and with the help of medications?
