Summary
This study looks at whether sleep and body-clock patterns can help predict delirium (sudden confusion) after major orthopedic surgery in adults aged 70 and older. Researchers will track sleep with a watch worn for two weeks before surgery and collect blood samples to check for Alzheimer's-related markers. The goal is to find early warning signs to prevent or manage post-surgery confusion.
