Purpose: Brivaracetam is often used as an alternative to levetiracetam in patients with epilepsy (PWE) encountering efficacy issues or adverse events with levetiracetam. This study evaluated the psychological status of PWE who were switched from levetiracetam to brivaracetam due to psychiatric tolerability concerns in comparison to those who remained on levetiracetam.
Methods: We used various psychological assessments including the Symptom Checklist SCL-90-R, the Beck Depression Inventory-II, and the adverse event profile. Eligible participants completed the questionnaires at baseline and again 8 days later. Psychological changes were assessed using standard statistical methods to show differences between a group that immediately switched from levetiracetam to brivaracetam and another group with unchanged levetiracetam.
Results: Between May 2020 and May 2021, 63 patients participated in the study, of whom 34 switched from levetiracetam to brivaracetam. At baseline, participants who switched to brivaracetam had fewer antiseizure medications but experienced more monthly seizures. Baseline scores for anxiety (p = 0.020) and psychoticism (p = 0.046) on SCL-90-R in PWE switched to brivaracetam were higher than in the remaining group. In the subsequent assessment, all psychological scores were reduced and were no longer significantly different between both groups. Using multiple regression, initial treatment with a single antiseizure medication and male gender emerged as predictors of psychological improvement.
Conclusion: Our study found no increased risk of adverse events or psychiatric symptoms after switching from levetiracetam to brivaracetam. Though statistically non-significant, a trend towards improved psychiatric outcomes in the switch group warrants further investigation in future trials with stronger designs for enhanced statistical power.
