A chronic neurological disorder characterized by excessive daytime sleepiness and sudden, uncontrollable episodes of falling asleep.
From Greek 'narke' (numbness, torpor) + 'lepsis' (an attack, seizure). Coined by Jean-Baptiste-Edouard Gelineau in 1880.
Narcolepsy makes your brain's sleep switch flip without warning — you can literally fall asleep mid-conversation, and it's not your fault at all.
