Insights
Children with new-onset epilepsy often have attention and executive function deficits before treatment. Cognitive function remains stable during early treatment, especially when epilepsy causes are unclear.
Area of Science:
- Pediatric Neurology
- Neuropsychology
- Epileptology
Background:
- New-onset epilepsy in children presents challenges to cognitive development.
- Attention and executive functions are crucial for academic and social functioning.
- Early identification of cognitive deficits is vital for intervention.
Purpose of the Study:
- To investigate attention and executive functions in children with new-onset epilepsy.
- To assess cognitive changes during early antiepileptic treatment.
- To identify predictors of cognitive impairment and changes.
Main Methods:
- Prospective longitudinal study of 76 children (6-17 years) with new-onset epilepsy.
- Utilized EpiTrack Junior® screening tool for attention and executive functions.
- Analyzed sociodemographic and epilepsy-related factors as predictors.
Main Results:
- Children with new-onset epilepsy showed more impaired attention/executive functions than healthy peers.
- Cognitive functioning remained largely stable during early treatment.
- Unknown epilepsy etiology increased risk of impairment; genetic epilepsy or unknown seizure semiology lowered improvement chances.
Conclusions:
- Children with new-onset epilepsy are at high risk for cognitive deficits, particularly with unclear etiology.
- Stable cognitive functioning during early treatment can alleviate parental concerns about medication side effects.
- Systematic cognitive assessment is essential for early detection and tailored treatment adjustments.
Objective:
Our prospective study aimed at exploring attention and executive functions in children with new-onset epilepsy prior to and during the early course of antiepileptic treatment. Sociodemographic and epilepsy-related factors were analyzed as potential predictors both of impaired cognitive functions as well as for changes in cognitive functioning in the early course of illness.
Methods:
From a total group of 115 children aged six to 17years without major disabilities, 76 children were assessed longitudinally with a screening tool for attention and executive functions (EpiTrack Junior®). Sociodemographic variables (gender, age at epilepsy onset, need of special education) and epilepsy-related variables (etiology of epilepsy, semiology of seizures, number of seizures) were considered as potential predictors for impaired functions prior to treatment and for deterioration/amelioration in cognitive functions in the early course.
Results:
Attention and executive functions of children with new-onset epilepsy were significantly more often impaired when compared with a healthy population, but less often when compared with children with chronic epilepsy. The majority of children showed stable cognitive functioning in the early course of treatment. The risk of impaired cognitive functions was significantly heightened when etiology of epilepsy was unknown or not classifiable. The chance for improvement of functioning was lowered by having a genetic epilepsy, or an unknown semiology of seizures.
Conclusions:
Children with new-onset epilepsy are at high risk for impaired attention and executive functions even prior to antiepileptic treatment, especially when etiology of their epilepsy remains unclear. The high stability of cognitive functioning in the early course can be used in counseling of families who worry about negative side effects of drug treatment. Finally, a systematic assessment of cognitive functions in children with new-onset epilepsy is necessary to detect subtle deficits in the early course and adjust treatment accordingly.
