One AI model to track body and mind from wearables
Wearables and AI are reshaping healthcare, but most tools track only physical diseases. That misses depression, which often coexists with chronic conditions. This study introduces one model that assesses multiple chronic diseases and depression together, using data from everyday sensors.
It treats each disease as its own task, so the model learns shared patterns while respecting differences. The twist tackles double heterogeneity: conditions manifest differently, and people with the same condition vary. The ADH-MTL method adds three upgrades: (1) group-level modeling to make reliable predictions for new patients, (2) a smart decomposition that reduces complexity, and (3) a Bayesian network—a probabilistic map—to capture how conditions relate without forcing them to look the same.
On real-world wearable datasets, ADH-MTL significantly outperformed existing approaches. The takeaway: integrated, body-and-mind insights can support collaborative care before, during, and after treatment. Paper: https://arxiv.org/abs/2511.16398v1
