Summary

Story summary

McMaster University researchers show wearables, such as smartwatches, can detect early signs of depression relapse weeks before symptoms appear.
The study, published in JAMA Psychiatry, followed 93 Canadian adults with major depressive disorder for up to two years.
Findings show irregular sleep patterns significantly increase relapse risk, suggesting passive tracking could shift care from reactive to proactive.
This approach may help providers intervene earlier and potentially prevent severe depressive episodes.
