The prevalence of narcolepsy (with cataplexy) is estimated between 1/3,300 and 1/5,000. [47] Although the true prevalence of IH is unknown, it is estimated at 1/10,000 to 1/25,000 for the long sleep form and 1/11,000 to 1/100,000 without long sleep. [48]

Upper airway resistance syndrome (UARS) is a clinical variant of sleep apnea that can also cause hypersomnia.
