What is narcolepsy?

Short Answer

Narcolepsy is a neurological sleep disorder marked by excessive daytime sleepiness and sudden sleep attacks. Some people also have cataplexy (sudden muscle weakness with emotion), sleep paralysis, and vivid hypnagogic hallucinations.

Why This Matters

This matters because narcolepsy disrupts the boundary between wake and REM sleep, which leads to dangerous sleepiness in daily life. Mislabeling it as “laziness” or depression results in delayed diagnosis and avoidable risk (driving, work accidents). Proper treatment and accommodations lead to safer functioning and better quality of life.

Where This Changes

Daytime sleepiness can also come from apnea, chronic sleep deprivation, or medications, so evaluation matters. If you have cataplexy, frequent sleep paralysis, or irresistible sleep attacks, it’s especially important to discuss symptoms with a sleep specialist.
