Comorbilidades neurocognitivas y psicológicas en pacientes con epilepsia de la infancia con puntas centrotemporales. Un estudio de casos y controles

Abstract

Introduction. Self-limited epilepsy with centrotemporal spikes (SeLECTS) is the most frequent self-limited focal epilepsy. This study aimed to assess the cognitive, behavioral, and other neuropsychological aspects of children with SeLECTS, and compare them with a control group. Subjects and methods. A case-control study was carried out between January and May 2022. Patients with SeLECTS, aged between 6 and 18 years, and followed-up at our hospital were selected for inclusion in the study. For each case, two age-matched controls were opportunistically recruited. All the participants performed the EpiTrack Junior® test, and their parents filled out the Child Behavior Checklist (CBCL). Results. Eighteen patients were included (mean age: 8.7 ± 1.7 years). At SeLECTS’ diagnosis, 83% of cases had adequate psychomotor development, and 17% had a neurodevelopmental disorder. The EpiTrack-Junior® and the Total Problems CBCL scores were not influenced by the laterality of the epileptic focus nor by the number of seizures. 61% of cases showed mild or significant impairment in the EpiTrack-Junior® test versus 44% of controls ( p = 0.712), and 39% of cases vs. 14% of controls had ‘clinically significant’ scores on the Total Problems CBCL scale ( p = 0.087). Conclusions. Although this study did not find statistically significant differences between cases and controls, it should be noted that most patients with SeLECTS had a mild or significant disability in executive functions. A considerable percentage of cases were in the pathological range regarding emotional/behavioral problems. This study highlights the importance of screening the cognitive, behavioral, and emotional problems in all patients with SeLECTS.
