Cenobamate Improves Emotional Dysregulation, Impulsivity, and Apathy in Drug-Resistant Focal Epilepsy: A Longitudinal Neuropsychological Study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionAlthough effects on cognitive function have been reported during cenobamate (CNB) treatment, far less is known about how it may affect neuropsychological domains such as apathy, emotion dysregulation, and impulsivity. This prospective longitudinal study aims to assess psychopathological and cognitive changes after CNB introduction in adults with drug-resistant focal epilepsy, accounting for seizure outcome and burden of concomitant anti-seizure medication (ASM).
methodsWe consecutively recruited adults with drug-resistant focal epilepsy who had undergone a comprehensive neuropsychological evaluation at baseline, before starting CNB, and at follow-up, 12 months after treatment introduction. The psychopathological battery included Beck Depression Inventory-II (BDI-II), State-Trait Anxiety Inventory, Difficulties in Emotion Regulation Scale (DERS-36), Barratt Impulsiveness Scale (BIS-11), Apathy Evaluation Scale (AES), and Quality of Life in Epilepsy Inventory (QoLIE-31). The cognitive assessment comprised Rey Auditory Verbal Learning Test (RAVLT), Digit-Span, Rey-Osterrieth Complex Figure Test, WEIGL, FAS, Stroop Color and Word Test, and Symbol Digit Modalities Test (SDMT). We applied linear mixed-effects models adjusted for responder status and total concomitant ASM defined daily dose (DDD) ratio.
resultsOur cohort included 27 individuals (16 female; mean age 42.4 ± 16.7 years) showing a 74% responder rate with 30% achieved seizure freedom at follow-up. CNB treatment was associated with favorable changes in BDI-II (q = 0.009), DERS-36 (q = 2.36 × 10
conclusionAdjunctive CNB was correlated with psychopathological improvements alongside domain-specific cognitive changes, independent of seizure outcome and concomitant ASM burden. These findings further expand current knowledge on CNB impact and tolerability profile.
