Predictive factors of quality of life in temporal and extratemporal lobe epilepsy: association with affective temperament profiles and psychiatric comorbidities

ABSTRACT

Background: Investigating predictive factors of reduced quality of life (QOL) of patients and their association with focal epilepsy can improve management and treatment strategies. Objective: This study aimed to investigate the relationship between affective temperaments, depression, anxiety, disease characteristics, and QOL and to explore the predictors of QOL in patients with temporal lobe epilepsy (TLE) and extratemporal lobe epilepsy (ETLE). Methods: A total of 50 patients with TLE, 51 patients with ETLE, and 70 controls were enrolled. Affective temperaments were evaluated using the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego-Autoquestionnaire (TEMPS-A). QOL was assessed by the Short-Form Health Survey (SF-36). Beck Depression Inventory and Beck Anxiety Inventory were used to explore depression and anxiety severity, respectively. Results: Compared with the controls, patients with TLE and ETLE had significantly higher scores on all TEMPS-A scales, except on hyperthymic temperament. All the SF-36 subscale scores were lower in the TLE and ETLE groups. Linear regression analysis revealed that depressive symptoms, anxiety, depressive and irritable temperament, and seizure frequency were significant predictors of QOL in TLE. Patients with ETLE with temperamental disturbances, depressive symptoms, and polytherapy had a poorer QOL. Conclusions: Affective temperaments, psychiatric disorders, and clinical factors may predict impaired QOL in patients with TLE and ETLE. Further studies are needed to identify predictors of QOL in various epilepsy subtypes.

RESUMEN

Antecedentes: Explorar los factores asociados y predictivos que reducen la calidad de vida en la epilepsia focal produce un efecto beneficioso en las estrategias de gestión y tratamiento. Objetivo: Investigar la relación entre temperamentos afectivos, depresión, ansiedad, características de la enfermedad y calidad de vida (QOL) y explorar los predictores de QOL en pacientes con epilepsia del lóbulo temporal (TLE) y epilepsia del lóbulo extratemporal (ETLE). Métodos: Se inscribieron un total de 50 pacientes con TLE, 51 pacientes con ETLE y 70 controles. Los temperamentos afectivos se evaluaron mediante el cuestionario de autoevaluación de Temperamento de Memphis, Pisa, París y San Diego (TEMPS-A). La calidad de vida se evaluó mediante la encuesta de salud de formato corto (SF-36). También se realizó a todos los participantes el Inventario de Depresión de Beck (BDI) y el Inventario de Ansiedad de Beck (BAI). Resultados: Los pacientes con TLE y ETLE tuvieron puntuaciones significativamente más altas en todas las escalas TEMPS-A que los controles, excepto la hipertimia . En la comparación de las puntuaciones del SF-36 dentro de cada grupo, todas las subescalas fueron más bajas en los pacientes con TLE y ETLE. El análisis de regresión lineal reveló que la depresión y la ansiedad, el temperamento depresivo e irritable y la frecuencia de las convulsiones fueron predictores significativos de la calidad de vida en el TLE. Además, los pacientes con ETLE con desequilibrios de temperamento afectivo, depresión comórbida y politerapia tenían una peor calidad de vida. Conclusiones: Los temperamentos afectivos, los trastornos psiquiátricos y los factores clínicos pueden predecir el deterioro de la calidad de vida en pacientes con TLE y ETLE. Se necesitan más estudios para descubrir los predictores de la calidad de vida en varios subtipos de epilepsia.
