• #8 From wakefulness to excessive sleepiness: what we know and still need to know

  https://pmc.ncbi.nlm.nih.gov/articles/PMC2362500/

  The epidemiological study of hypersomnia symptoms is still in its infancy; most epidemiological surveys on this topic were published in the last decade. […] Excessive daytime sleepiness (EDS) has been mostly investigated in terms of frequency or severity; duration of the symptom has rarely been investigated. EDS occurring at least 3 days per week has been reported in between 4% and 20.6% of the population, while severe EDS was reported at 5%. […] The term excessive daytime sleepiness is often used interchangeably with hypersomnia. This usage is partly correct; hypersomnia is a broader symptom including extended nocturnal sleep, unplanned daytime sleep and an inability to remain awake or alert in situations where it is required (excessive sleepiness). […] Excessive daytime sleepiness is not a disease or a disorder; it is a symptom of a sleep disorder or of another disease.
