Dear Community,
We are excited to announce the opening of the George B. Moody PhysioNet Challenge 2026. The 2026 Challenge invites teams to develop algorithms for using polysomnograms (PSGs) to predict cognitive impairment from sleep studies.
Sleep is a fundamental physiological process that is deeply intertwined with human health. Traditionally, clinicians use sleep studies to diagnose obstructive sleep apnea, insomnia, and other sleep disorders. However, sleep studies can also reveal other chronic conditions that cause, are caused by, or are correlated with physiological changes in sleep. These findings can provide context to sleep disorders and inform the early diagnosis and treatment of other health conditions.
We have shared multicenter Challenge training data containing EEG, ECG, and other physiological signals and algorithmic and human sleep annotations as well as an example Challenge entry that you can use as a template for your entries. We will open the scoring system in the coming days.
As in previous years, we have divided the Challenge into two phases: an unofficial phase and an official phase. The unofficial phase solicits feedback from the research community (i.e., you) to help us improve the Challenge for the official phase, so we require teams to register and participate in the unofficial phase of the Challenge for prize eligibility. Please enter early and often – we need you to look for quirks in our data, our scoring system, and otherwise. We are imperfect (and bandwidth-limited), so please send us suggestions via the forum (see below). We rely on the community to help us to improve the quality of the Challenge each year.
The culmination of the Challenge will be in Spain at the annual meeting of Computing in Cardiology, where we will present prizes at the closing ceremony.
We will post more information on the PhysioNet Challenge website and Challenge forum as it becomes available, or when your input helps us modify the boundaries and content. Please post questions and comments to the Challenge forum as well. However, if your question reveals information about your entry, then please email info [at] physionetchallenge.org instead to help us safeguard the diversity of approaches to the Challenge. We may share parts of our replies publicly if we feel that all Challengers should benefit from the information contained in our responses. We will not answer emails about the Challenge sent to other email addresses.
We thank you for your continued interest and support, and we hope that you enjoy the 2026 Challenge!
Best,
