title: Which patients become seizure free with antiepileptic drugs? An observational study in 821 patients with epilepsy.
abstract: OBJECTIVE
  Analysis of factors influencing seizure outcome in antiepileptic drug treatment of epilepsy.
  
  
  METHODS
  Retrospective analysis of 500 patients with complete seizure control and 321 patients with refractory epilepsy (mean ages 33.3 and 32.1 years respectively).
  
  
  RESULTS
  The seizure-free group consisted of 377 patients with symptomatic/cryptogenic epilepsy (SCE; mean seizure control 45 months) and 123 patients with idiopathic generalized epilepsy (IGE; mean seizure control 61 months) (P = 0.02). Of the patients with SCE, 35.7% had achieved seizure control with monotherapy (MT), 29.6% with >or=2 AEDs. No single AED was superior in MT. Of the patients with IGE, 35.9% had become seizure free with MT, 15.6% on combination therapy (CT). Valproate MT was more commonly associated with seizure freedom than lamotrigine (P < 0.05).
  
  
  CONCLUSIONS
  The results indicate that, in SCE, seizures can be controlled with carefully selected CT more commonly than suggested by previous studies. The seizure prognosis of patients with IGE presenting to a specialist in epilepsy may be worse than previously thought.
