Purpose:Valproic acid (VPA) is frequently used and effective in juvenile myoclonic epilepsy (JME). Recently, levetiracetam (LEV) has been suggested as a monotherapy in JME. This study aimed to evaluate antiseizure medication (ASM) use in patients with JME. Methods: Treatment choices in a total of 257 patients (age range 8–18 years, 152 girls, 105 boys) with JME diagnosed and treated between 2010 and 2020 were evaluated retrospectively. Seizure remission was defined as complete seizure control for at least 12 months. Results: Across the study period and entire patient group, VPA was most commonly chosen as the initial ASM (50.9%), followed by LEV (44.4%), and lamotrigine (4.7%). VPA was also the most frequent first choice in the subgroup of boys (73.3%), while LEV was the commonest first choice in girls (57.9%). The sex difference regarding the ASM of the first choice was statistically significant (p<0.001). While VPA was the most frequent initial ASM in the first 5 years of the study period (2010–2015,n = 66, 64%), LEV had taken over as the most popular first ASM in the last 5 years (n = 83, 53.9%, p = 0.005). The most frequent reasons for discontinuation were inefficacy for LEV and adverse effects for VPA (p = 0.001). During follow-up, 237 patients (92.2%) were seizure-free for at least 12 months, and 159 (61.9%) were also in electrographic remission. Seizure remission occurred earlier than electroencephalographic remission (p<0.001). Conclusion: This study revealed that LEV has become the most frequently chosen initial ASM in the treatment of JME. Although LEV appears to have a better adverse effect profile, VPA seems more likely to be effective in achieving seizure control.
