Predicting mood episode recurrence in bipolar and depressive disorders
Official title: Prediction on the Recurrence of Manic and Depressive Episodes in Bipolar Disorder
Run by National Taiwan University Hospital · NCT05828056 · Data updated 2026-11-12
A wearable-based study to see if heart rate, sleep, activity, and mood data from a smartwatch can help predict when manic or depressive episodes will come back in people with bipolar or depressive disorders.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 20–60 with DSM-5 bipolar or depressive disorder who are willing to wear a smartwatch and use a smartphone most of the time.
✕Probably not a fit
Participants who do not experience relapse during the observation period or whose data do not support predictive accuracy may not derive direct benefits.

What this trial studies
This observational study follows 100 adults with bipolar or depressive disorders over one year using a wearable smartwatch and smartphone to collect physiological and behavioral data. Researchers will annotate mood states (manic, depressive, or euthymic) and build models to predict recurrence of mood episodes. The goal is to enable earlier clinical intervention if relapse is detected by the data patterns. The study focuses on leveraging continuous monitoring to improve forecasting of mood episode recurrence. No intervention is being tested beyond data collection and model development.
Why it matters
Potential benefit: If successful, the model could help clinicians anticipate relapses and intervene earlier to reduce worsening of mood symptoms.
How similar studies have gone: Prior research has shown promise for wearable data in mood disorder monitoring, but robust predictive models for recurrence remain an area of active development.
