What this trial studies

This observational study aims to prospectively evaluate patients diagnosed with Cushing's syndrome, focusing on their physical function, quality of life, and circadian rhythms both before and after treatment. The study hypothesizes that Cushing's syndrome adversely affects health-related quality of life and physical functioning, and that these issues may improve following effective treatment. By analyzing changes in circadian rhythms at the whole body level and in specific tissues, the study seeks to provide insights into the broader impacts of the syndrome and its management.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 years old with a new diagnosis of Cushing's syndrome of endogenous origin.

Not a fit: Patients with active cancer, severe chronic diseases, or those unable to safely participate will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of how Cushing's syndrome affects patients' lives and inform better treatment strategies.

How similar studies have performed: While the specific approach of this study is observational, similar studies have shown success in understanding the impacts of chronic conditions on quality of life.
