Semantic Notes
The core medical condition involves two primary symptoms: excessive daytime sleepiness (EDS) and cataplexy, though not all diagnosed individuals experience the latter. The term is used precisely in medicine and psychology.

FAQ
Frequently Asked Questions
No, it's a specific neurological disorder. While excessive daytime sleepiness is primary, it often includes symptoms like cataplexy (sudden muscle weakness), sleep paralysis, and hallucinations.
There is currently no cure for narcolepsy, but its symptoms can be effectively managed with medication, scheduled naps, and lifestyle adjustments.
It is considered relatively rare, affecting an estimated 1 in 2,000 people, though it may be underdiagnosed.
Narcolepsy involves irresistible 'sleep attacks' and REM sleep abnormalities (like cataplexy) that occur regardless of how much night-time sleep a person gets, unlike general fatigue or sleep deprivation.
