| Summary: | Abstract Objective The aim of this study was to evaluate the clinical features and treatment outcomes of patients with juvenile myoclonic epilepsy (JME) in western China. Method We continuously reviewed one hundred and five outpatients with JME who were diagnosed and treated at the Epilepsy Registration Center of West China Hospital between October 2012 and July 2014. Seizure control stratified into different seizure types and by antiepileptic drugs (AEDs) was prospectively evaluated every 3‐6 months. Results Among 105 patients with JME, eighty‐five patients (81%) received monotherapy including valproate (VPA, 47%) and levetiracetam (LEV, 43%) treatment. The rates of seizure freedom 1, 3, and 5 years after the initiation of AED treatment were 64.8% (68/105), 29.5% (31/105), and 14.6% (12/82) in JME patients, respectively. Patients with myoclonic seizure (MS) and absence seizure (AS) were less frequently seizure‐free than those with MS and generalized tonic‐clonic seizure (GTCS) (P = 0.012). Patients on VPA monotherapy had better control of GTCS than patients on LEV monotherapy (P = 0.036). There is a trend of lower rates of seizure freedom in patients treated with LEV than in those treated with VPA after the first‐year treatment period. Significance Our data suggest that in JME, seizure control is linked to seizure type, possibly allowing a more individualized approach when counseling JME patients.
