Differential improvement of the sleep quality among patients with juvenile myoclonic epilepsy with valproic acid: A longitudinal sleep questionnaire-based study
OBJECTIVES: The aim of this study was to assess the effect of sodium valproic acid (SVA) on the sleep quality of patients with juvenile myoclonic epilepsy (JME). MATERIALS AND METHODS: Standardized sleep questionnaires viz. Epworth Sleepiness Scale (ESS) and Pittsburgh Sleep Quality Index (PSQI) wer...

description | OBJECTIVES: The aim of this study was to assess the effect of sodium valproic acid (SVA) on the sleep quality of patients with juvenile myoclonic epilepsy (JME). MATERIALS AND METHODS: Standardized sleep questionnaires viz. Epworth Sleepiness Scale (ESS) and Pittsburgh Sleep Quality Index (PSQI) were administered to 30 drug-naïve patients with JME (male:female (M:F) = 14:16; age: 21 ± 3.7 years) and the changes following SVA monotherapy was analyzed using t- and chi-squared tests. RESULTS: The mean age at onset of seizures and diagnosis was 15.43 ± 3.8 and 21 ± 5.1, years respectively. All had myoclonic jerks with mean duration of 5.23 ± 2.7 years, aggravated by sleep deprivation (23, 76.7%) and sleep-wake transition (29, 96.7%). Twenty-seven (90%) had generalized tonic-clonic seizures (GTCS), majority (70%) on awakening from sleep. Seizures were controlled in 25 patients (83.33%) with SVA monotherapy. Abnormal ESS was noted in five (16.66%) drug naïve patients compared to six (20%) patients while on SVA (P = 0.782). Mean ESS remained unchanged before and after SVA therapy (6.27 ± 4.4 vs 6.97 ± 4.7, P = 0.262). On the other hand, only four (13.3%) patients had abnormal PSQI scores at follow-up after initiation of SVA, as compared to 14 (46.7%) subjects in the drug naïve state (P = 0.037). Further, we also found significant reduction in mean PSQI scores after initiating SVA monotherapy (6.7 ± 5.6 vs 2.7 ± 2.84, P £ 0.0001). CONCLUSION: This study showed that the mean PSQI as well as the number of patients with abnormal PSQI significantly reduced after initiating SVA therapy, suggesting a significant improvement in night-time sleep quality with SVA treatment. However, SVA therapy did not alter ESS. |
