Insights
Children with typical absence seizures (TAS) experience higher rates of sleep and attention disorders. Early identification and management of these sleep disorders can improve quality of life and academic outcomes.
Area of Science:
- Pediatric Neurology
- Sleep Medicine
- Developmental Psychology
Background:
- Typical absence seizures (TAS) are a common epilepsy syndrome in children.
- Sleep disorders (SD) and attention deficit hyperactivity disorder (ADHD) symptoms are frequently observed in children with epilepsy.
- The interplay between TAS, SD, and ADHD symptoms requires further investigation.
Purpose of the Study:
- To compare the prevalence of SD and ADHD symptoms in children with TAS versus controls.
- To examine the influence of epilepsy-related factors on sleep and attention in children with TAS.
Main Methods:
- A cohort of 82 children (41 with TAS, 41 controls), aged 5-15.6 years, participated.
- Parents completed the Sleep Disturbance Scale for Children (SDSC) and ADHD rating scales.
- For children with TAS, the Pediatric Epilepsy Side Effects Questionnaire was used to assess medication side effects.
Main Results:
- Children with TAS exhibited significantly higher scores for subjective sleep and attention disorders, particularly excessive diurnal sleepiness and inattention.
- Sleep problems were under-reported by parents in the TAS group.
- In children with TAS, inattention risk was higher in boys, those with high BMI, or those experiencing anti-seizure medication (ASM) side effects.
Conclusions:
- Children with TAS are at increased risk for both sleep and attention disorder symptoms.
- Sleep disorders in children with epilepsy are often underestimated and warrant focused assessment.
- Addressing sleep disorders in children with TAS may enhance academic performance, quality of life, and seizure control.
Objective:
To assess the occurrence of sleep disorders (SD) and attention deficit hyperactivity disorder (ADHD) symptoms in children with typical absence seizures (TAS) compared to control children and to evaluate the impact of epilepsy-related factors on sleep and attention in children with TAS.
Methods:
The Sleep Disturbance Scale for Children (SDSC) and the ADHD rating scale were filled in by parents of a cohort composed by 82 children aged from 5 to 15.6 years, 49% of boys (41 with TAS with a syndromic diagnosis of childhood absence epilepsy and 41 controls). For children with TAS, the Pediatric Epilepsy Side Effects Questionnaire was completed. Statistical analyses were conducted in order to compare sleep and attention scores between groups. In children with TAS, a correlation was computed between these scores. Logistics regression models were conducted to identify predictors of excessive diurnal sleepiness and inattention in children with TAS.
Results:
Compared to controls, children with TAS had higher total scores for subjective sleep (mean 42.9 vs 38.3, p = 0.05) and attention disorders (mean 16.8 vs 11.6, p = 0.01), especially for excessive diurnal sleepiness (mean 3.9 vs 3.2, p = 0.02) and inattention (mean 9.3 vs 5.6, p = 0.003) components. In children with TAS, sleep problems were significantly under-reported by parents. Sleep disorders symptoms as breathing-related sleep disturbance, excessive diurnal sleepiness or naps at or after 7 years of age were reported. Subjective sleep and attention disorders were significantly correlated (r = 0.43, p = 0.01). Subjective excessive diurnal sleepiness may be the result of a polytherapy (p = 0.05) or a side effect of anti-seizure medication (ASM) (p = 0.03) but children without medication side effects also reported subjective SD. In children with TAS, the risk of inattention symptoms was increased in boys (p = 0.02), with a high BMI (p = 0.05), or with ASM side effects (p = 0.03).
Conclusions:
This study demonstrates that children with TAS are at risk of sleep and attention disorder symptoms. If attention disorders in a context of epilepsy are now widely assessed and identified, sleep disorders are still under-estimated. An accurate identification and management of sleep disorders could improve academic performances, quality of life, and seizure management in children with TAS.
