Investigation of stress hormones across multiday seizure cycles

Stirling et al. · Brain Communications (2026)

Saliva cortisol tracked across predicted high- and low-risk periods shows hormone levels rise at the peak of a person's multiday seizure cycle.

More variable circadian rhythms in epilepsy captured by long-term heart rate recordings from wearable sensors

Smith et al. (Stirling, co-author) · Epilepsia (2025)

Long-term wearable heart-rate data shows people with epilepsy have more variable circadian rhythms than those without.

Wong et al. · Epilepsia (2026)

Distinguishes menstrual-linked seizure patterns from other multiday cycles that can look similar on the surface.

The circadian profile of epilepsy improves seizure forecasting

Karoly et al. · Brain (2017)

Shows that accounting for a person's circadian seizure pattern improves the accuracy of seizure forecasting algorithms.

eBioMedicine, October 2021 cover: Multiday cycles of heart rate are associated with seizure likelihood Cover Feature
Publication

Multiday cycles of heart rate are associated with seizure likelihood

An observational cohort study · eBioMedicine (2021)

Wearable heart-rate data reveals circadian, weekly and monthly cycles in nearly all participants, with seizures phase-locked to these cycles in many people with epilepsy.

Publication

Sleep and seizure risk in epilepsy: bed and wake times are more important than sleep duration

Stirling et al. · Brain (2023)

Wearable sleep tracking shows consistent bed and wake times matter more for seizure risk than how long someone sleeps.
