This is a research registry — a long-term study that collects medical information from patients with sleep disorders like narcolepsy, sleep apnea, insomnia, and restless legs syndrome. The goal is to follow how these conditions develop over time and how they affect people's quality of life. Some participants may also be receiving vagus nerve stimulation (a nerve-based treatment), and researchers want to track how that affects their outcomes too.
Sleep disorders affect millions of people, but we still don't fully understand how these conditions progress or how different treatments impact patients' daily lives. This registry will help doctors identify patterns, improve care, and eventually develop better treatments.

You'll be asked to share your medical history — such as when your sleep disorder started, what medications you've tried, and how severe your symptoms are. Going forward, you'll also complete surveys about your quality of life and how your condition affects your daily activities. The study is ongoing, so you may be contacted periodically to update your information.
