Sleep Disorders in Epilepsy: Current Trends and Future Perspectives

Chronotype variability in epilepsy and clinical significance: scoping review

PURPOSE

Chronotype, which captures a person's daily preferences for activity and sleep, is still a poorly researched area in epilepsy research. Finding common chronotype characteristics in people with epilepsy (PWE) and explaining possible effects on seizure management are the main goals.

METHODS

Eleven large-scale investigations from 2010 to 2023 were examined in this scoping review. These studies included 1.167 PWE and 4.657 control subjects.

RESULTS

PWE had intermediate chronotypes more often than not. Adult patients were more morning-oriented overall, while pediatric cohorts were variable. Relationships between chronotype and seizure control were limited since only two studies in adults reported this and those results conflicted. An evening-type chronotype was found to be more common in generalized epilepsy than focal. The relationship of chronotype and specific antiseizure medication (ASM) therapy was not investigated.

CONCLUSIONS

The majority of PWE displayed an intermediate chronotype, but analyses based on age showed more nuanced trends, with children displaying variable patterns, adults generally tending toward morningness, and generalized epilepsy being associated with eveningness. This review underscores the importance of more research on the complex connections between epilepsy outcomes and chronotype. It emphasizes the need to study larger samples of PWE with carefully documented seizure control and ASM therapy, including dose and timing of administration to better understand the role of chronotype on epilepsy outcomes.

Associations between 24-hour movement guideline adherence and mental health disorders among young people with active and inactive epilepsy

OBJECTIVE

(1) Examine 24-hour movement guideline adherence among young people with active and inactive epilepsy compared to population norms. (2) Investigate associations between 24-hour movement guideline adherence and mental health disorders among these subpopulations.

METHODS

Cross-sectional data from the 2016 to 2019 cycles of the National Survey of Children's Health were used. Parental/caregiver reports of movement behaviors (physical activity, screen time, sleep, and sport participation) were used to determine adherence to the 24-hour movement guidelines and associations with mental health disorders for young people with active (n = 663) and inactive epilepsy (n = 526) as well as population norms (n = 49,067) between 6 and 17 years old. Multivariate logistic regression analyses were conducted.

RESULTS

Young people with active epilepsy were less likely to meet the 24-hour movement guidelines than population norms, largely driven by below average levels of physical activity guideline adherence. Sport participation was lower among both young people with active and inactive epilepsy; seizure severity and health-related limitations played an influential role. Beneficial associations were generally observed between 24-hour movement guideline adherence and mental health disorders, although for young people with active and inactive epilepsy, there was considerable variability among these relationships.

CONCLUSIONS

Further dissemination of the International League Against Epilepsy's Task Force on Sports and Epilepsy report can help improve promotion of physical activity and sport participation among young people with active and inactive epilepsy. The relationship between 24-hour movement guideline adherence and mental health disorders is complex among young people with epilepsy and longitudinal research is needed to determine causal links.
