New data from Project Sleep’s Narcolepsy and IH Social Support Survey will be presented in a late-breaking abstract poster at SLEEP 2024, June 1-5 in Houston, TX.

The study, “Evolving Diagnostic Patterns in Central Disorders of Hypersomnolence: Has Time to Diagnosis Gotten Shorter Over The Last Decades?” examines diagnostic patterns in hypersomnolence (i.e., narcolepsy and idiopathic hypersomnia) over time. In their analysis of 1272 survey responses, the authors found that while diagnoses of narcolepsy and IH have increased steadily since the early 2000s, there is no clear evidence of a reduction in time to diagnosis after onset of symptoms.

Independent researcher and study co-author Eileen B. Leary, PhD, RPSGT will present the poster during the conference. Co-authors are Julie Flygare, JD; Lauren Oglesby, MPH; Kiran Maski, MD, PhD; and Lucie Barateau, MD, PhD.

Thank you!

Huge thanks to the 1272 survey participants! Your insights make it possible for us to shed light on issues that deeply affect people with sleep disorders, and we are beyond grateful for your time, energy, and willingness to share.

Special thanks to our study co-authors for your incredible collaboration and expertise. We are excited to share this research at SLEEP 2024!


SLEEP is the annual meeting of the Associated Professional Sleep Societies, LLC (APSS). The APSS is a joint venture of the American Academy of Sleep Medicine (AASM) and the Sleep Research Society (SRS).
