Circadian Phase Locking of Epilepsy Seizures in Wearable Data: A Single-Patient Case Study

A CHI 2026 workshop paper examining circadian phase relationships in epilepsy seizures using longitudinal wearable data.

Overview

This workshop paper investigates whether epileptic seizures exhibit consistent circadian phase relationships that can be identified using longitudinal wearable data from a single participant.

The work demonstrates how wearable-derived physiological measurements can be used to characterise recurring biological rhythms and discusses their potential for personalised health monitoring.

This research represents an early step towards leveraging cyclical physiological information for personalised health technologies and future AI-driven decision support.
