Accurately predicting mood episodes in mood disorder patients using wearable sleep and circadian rhythm features
Using wearable sleep and daily rhythm data to predict mood episodes in mood disorder patients
AI simplified
Abstract
168 patients were monitored, yielding accurate predictions for mood episodes based on sleep-wake data.
- Models developed predict future mood episodes using only sleep-wake data collected through smartphones and wearables.
- An average of 587 days of clinical follow-up and 267 days of wearable data were analyzed.
- The derived 36 sleep and circadian rhythm features enabled next-day predictions for depressive, manic, and hypomanic episodes with AUCs of 0.80, 0.98, and 0.95, respectively.
- Daily shifts were identified as significant predictors: delays in sleep onset were associated with depressive episodes, while advances were linked to manic episodes.
- This prospective observational cohort study indicates the potential of sleep-wake data and prior mood episode history for mood episode prediction.
