- Falling
BACKGROUND: Despite extensive research on falls among individuals with stroke, little is known regarding the impact of neurological conditions with comorbid diagnoses and motor functional capacity on the risk of falls in these individuals. [medworm.com]
This has several consequences: Nighttime sleep does not include much deep sleep, so the brain tries to "catch up" during the day, hence EDS May visibly fall asleep at any moment (such motions as head bobbing are common) People with narcolepsy fall quickly [wikidoc.org]
Hypocretin, or Orexin, is a chemical that helps a person stay awake and avoid falling asleep. [yourceus.com]
