Frailty as a comprehensive health measure beyond seizure control in patients with epilepsy: A cross-sectional study.

OBJECTIVE: Due to the high clinical heterogeneity of epilepsy, there is a critical need for novel metrics aimed at capturing its biological and phenotypic complexity. Frailty is increasingly recognized in various medical disciplines as a useful construct to understand differences in susceptibility to adverse outcomes. Here, we develop a frailty index (FI) for patients with epilepsy (PwE) and explore its association with demographic and clinical features. METHODS: In this cross-sectional study, we consecutively enrolled 153 PwE from an outpatient epilepsy clinic. Participants were assessed for various health deficits to calculate the FI. Associations between FI and demographic/clinical features, antiseizure medications (ASMs), and patient-reported outcomes were analyzed using general linear models and Spearman correlation. RESULTS: The median age at the time of study visit was 47 years (interquartile range = 33-60), and 89 (58.2%) patients were females. Multiple linear regression revealed that the developed 33-item FI showed an independent association with age, female sex, higher body mass index, family history of epilepsy, intellectual disability, and the number of ASMs used. A robust analysis of covariance showed higher FI levels in patients using cytochrome P450 3A4-inducer ASMs. We found a moderate positive correlation between FI and psychological distress, lower quality of life, and physical frailty, measured by the Hospital Anxiety and Depression Scale, Quality of Life in Epilepsy Inventory-10, and handgrip strength, respectively. Finally, a weak association was observed between higher FI scores and an increased number of epileptic falls. SIGNIFICANCE: This study highlights the significance of frailty as a comprehensive health measure in epilepsy. It suggests that frailty in this specific population is not only a manifestation of aging but is inherently linked to epilepsy and treatment-related factors. Future research is warranted to validate and refine the FI in diverse epilepsy populations and investigate its impact on specific adverse outcomes in longitudinal studies.

Cognitive behavioral therapy in adults with functional seizures: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Randomized controlled clinical trials (RCTs) investigating cognitive-behavioral therapy (CBT) among adults with functional seizures (FS) have become increasingly available, prompting the opportunity to critically appraise the efficacy and safety of CBT in this population. METHODS: We conducted a systematic review and meta-analysis including RCTs comparing CBT in addition to standardized medical treatment (SMT) versus SMT alone for adults with FS. The primary outcome was seizure freedom at the end of treatment. Secondary outcomes included measures of quality of life, anxiety and depression assessed via standardized clinical questionnaires. RESULTS: Three RCTs were included comprising 228 participants treated with CBT and 222 with SMT. The intervention was significantly associated with seizure freedom (Odds Ratio [OR] 1.98; 95 % confidence interval [CI] 1.14, 3.46; p = 0.02; I2 = 0 %), reductions in anxiety (standardized mean difference [SMD] -0.21; 95 % CI -0.41, -0.003; p = 0.047; I2 = 0 %) and improvements in quality of life (SMD 0.34; 95 % CI 0.12, 0.57; p = 0.003; I2 = 0 %) at the end of treatment. Conversely, no significant differences between groups were observed in depression symptoms (SMD -0.19; 95 % CI -0.39, 0.02; p = 0.08; I2 = 0 %). There was no statistically significant increase in the risk of suicidal ideation and self-harm with CBT (OR 2.11; 95 % CI 0.81, 5.48; p = 0.13; I2 = 0 %) nor were there differences in terms of discontinuation rates during follow-up (OR 0.92; 95 % CI 0.49, 1.72; p = 0.79; I2 = 7 %). CONCLUSIONS: There is high-quality evidence supporting the efficacy and safety of CBT in treating FS. Future research should investigate whether combining CBT with other therapeutic methods could potentially enhance treatment efficacy.
