Objectives: To assess state and trait anger, adjusted by epilepsy type, seizure control, anxiety-depression status and quality of life, in patients treated with brivaracetam (BRV) from an open study.
Methods: We evaluated prospectively consecutive patients with partial onset seizures in an open-label study. Patients had 5 years or longer of epilepsy and were taking between 1 and 3 antiepileptic drugs. They were treated with BRV and compared with a control group selected from outpatients attending our epilepsy unit who met the following criteria: age ≥16 years and diagnosis of epilepsy with focal-onset seizures at least 1 year before inclusion in the study. The following tests were assessed: State-Trait Anger with the Expression Inventory-2, Hospital Anxiety and Depression Scale, and Quality of Life in Epilepsy Inventory.
Results: We recruited 39 patients, 17 treated with BRV and 22 with other drugs, including 13 with levetiracetam (LEV). Mean age was 47.3 years, 43.6% were men. Symptomatic cases, 66% and 52% temporal lobe epilepsy. Antiepileptic drug polytherapy was present in 82.1% of the cases (100% BRV vs 68.2% control group). Demographic and clinical characteristics, as well as Quality of Life in Epilepsy Inventory and Hospital Anxiety and Depression Scale scores were similar in both groups. When compared with the subgroup of LEV groups did not differ significantly on their Hospital Anxiety and Depression Scale scores.
Conclusions: This small, open study suggests that BRV increases anger measures less than LEV in epilepsy patients. However, larger, blinded control studies are required to establish whether this apparent difference can be confirmed.
