Features of EDS are as follows:

  • EDS is the primary symptom of narcolepsy

  • EDS must be present for at least 3 months to justify the diagnosis

  • Severe EDS leads to involuntary somnolence during activities such as driving, eating, or talking

  • Sleepiness may be severe and constant, with paroxysms of falling asleep without warning (ie, sleep attacks)
