PURPOSE OF REVIEW: The treatment of epilepsy in children is highly individualized at each and every major step in the management. This review examines various factors that modify the treatment from the point of initiation of therapy to the decision to stop an antiepileptic drug (AED).

RECENT FINDINGS: AED therapy leads to seizure freedom in about 70% of all children with epilepsy. AED initiation could be delayed until a second seizure in most children and may be avoided altogether in many children with self-limited childhood focal epilepsies. Three key factors influence the choice of AED: seizure type(s), efficacy of the drug for the seizure type, and the side effect profile of the drug(s). For epileptic spasms, steroids and vigabatrin are the most effective treatment options. For absence seizures, ethosuximide and valproic acid are superior to lamotrigine. For focal seizures, many newer AEDs have favorable side effect profiles with efficacy comparable to older-generation drugs. For generalized epilepsies, valproic acid remains the most effective drug for a broad range of seizure types. Genetic and metabolic etiologies may guide unique treatment choices in some children. After 2 years or more of seizure freedom, if the recurrence risk after AED withdrawal is acceptable, slow weaning of AEDs should be done over the span of 6 weeks or longer. After discontinuation, about 70% of patients remain seizure free, and of those with recurrence, the majority achieve seizure control with restarting an AED. When treatment with two or more AEDs fails, other treatment opportunities for drug-resistant epilepsy, including epilepsy surgery, vagal nerve stimulation, and dietary therapies should be considered.

SUMMARY: Carefully selected medical therapy guided by seizure type and AED characteristics is effective in more than two-thirds of children with epilepsy.
