Investigating how sleep disturbances may predict delirium and Alzheimer's disease after heart surgery

Sleep-Wake Disturbance as a Predictor of Delirium and Subsequent Alzheimer's Disease and Related Dementias after Surgical Aortic Valve Replacement

NIH-funded research University of Rochester · NIH-11035126

This study is looking at how sleep problems might affect the chances of developing confusion or Alzheimer's disease in older adults who are having heart valve surgery, and it aims to help doctors better care for these patients by tracking their sleep and thinking skills before and after the surgery.

What this research studies

This research focuses on understanding the connection between sleep-wake disturbances and the risk of developing delirium and Alzheimer's disease in patients undergoing surgical aortic valve replacement. By using actigraphy and home sleep tests, the study aims to objectively assess sleep patterns before surgery and their potential link to postoperative cognitive issues. The goal is to improve care for older adults by identifying those at higher risk for these conditions, ultimately enhancing clinical outcomes. Participants will be monitored over time to gather data on their sleep and cognitive health.

Who could benefit from this research

Good fit: Ideal candidates for this research are adults aged 21 and older who are scheduled for surgical aortic valve replacement.

Not a fit: Patients who are not undergoing surgical aortic valve replacement or those with pre-existing severe cognitive impairment may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to better prevention strategies for delirium and Alzheimer's disease in at-risk patients.

How similar studies have performed: Previous research has shown promising results in linking sleep disturbances to cognitive decline, suggesting that this approach may yield valuable insights.
