Manifestations of EDS are not always obvious2,4,5

  • Inability to stay awake and alert2
  • Lapses in vigilance or concentration2,5
  • Patients may describe “tiredness” or “fatigue”5
  • Irrepressible need for sleep2
  • Unintended lapses into drowsiness or sleep2

Since all people with narcolepsy have chronic daily EDS, it is important to be aware of the different manifestations2,5

  • Drooping of the eyelids (ptosis)
  • Facial hypotonia
  • Mouth opening
  • Tongue protrusions
  • Positive motor phenomena (facial jerks, grimaces)

Patients may knowingly or unknowingly avoid situations that could trigger symptoms3,9,10

In a national survey of 200 people living with narcolepsy9,*:

*Data from a 3-part survey of 1654 US adults including those with narcolepsy (n=200), the general public (n=1203), and physicians (n=251) currently in clinical practice who have treated patients with narcolepsy in the last 2 years. Surveys of people with narcolepsy and the general public were conducted online in March and April 2018, and physicians were surveyed in August 2018. Versta Research conducted the survey on behalf of Harmony Biosciences.9 The Narcolepsy Network collaborated on the patient survey. Eighty-four percent (n=169) of respondents with narcolepsy were taking medications for their narcolepsy. For these responses, patients were asked their perspectives on all their narcolepsy symptoms (not specific to EDS or cataplexy) as well as the disorder in general.9
