question: My son is 2.5 years old and weighs 12 kilos. he was diagonosed with seizures (non febrile) slightly over an year ago and was been on Sodium Valproate since. He has not had any seizures in the last 11 months. He has recently started a play group and seems to be very aggressive and hits kids and pulls their hair compared to other kids. Some people tell me aggression is a side effect of valproate. Is that true? What can I do to help?
