Take a second to think about what narcolepsy seems like — if you happen to’re going by the favored notion, you will have envisioned somebody who’s continually yawning and spends most of their time napping. Although narcolepsy is actually characterised by unwarranted sleepiness, the truth of the dysfunction is a bit more difficult.
First of all, understanding narcolepsy begins with understanding what typical sleep seems like. According to the American Sleep Association, sleep proceeds by 5 phases: One, two, three, 4, and fast eye motion (REM), although not essentially in that order. The REM stage, which happens roughly 90 minutes right into a sleep cycle, is when the mind is most lively; maybe unsurprisingly, analysis has proven that is when most dreaming happens. Unless sleep is (rudely) interrupted, the mind sometimes cycles by these phases 4 or 5 occasions an evening.
For individuals with narcolepsy, nevertheless, sleep seems very totally different. “Narcolepsy is a disorder in which the duration of REM sleep is impaired,” explains Dr. Milena Pavlova, a neuroscientist with the Division of Sleep and Circadian Disorders at Brigham and Women’s Hospital, to Bustle in an interview. Rather than biking by different phases earlier than they get to REM sleep, individuals with narcolepsy drop nearly instantly into REM sleep, and so they are inclined to expertise fragments of REM sleep all through the day. Furthermore, they’ve issue controlling their sleep-wake cycles, so that they go to sleep shortly and unwillingly.
These “attacks” of sleepiness are the premise of narcolepsy, however they don’t seem to be the one symptom. Let’s check out 5 indicators of narcolepsy beneath.

Rather, they sleep in brief bursts all through the day, and so they could even discover themselves unable to go to sleep at evening. The downside is that they cannot management after they sleep.
“[People with narcolepsy] don’t have a larger quantity of sleep,” Dr. Milena Pavlova tells Bustle. “It’s that their duration of REM sleep is impaired.”
2. Falling Asleep Unwillingly
Most individuals have dozed off after they should not, however there is a distinction between pulling a couple of too many all-nighters and actually being unable to remain awake for lengthy durations of time, even in harmful conditions. According to Dr. Pavlova, the persistent “attacks” of sleepiness characterizing narcolepsy can severely disrupt each day life.

During REM sleep, the physique’s muscle mass are relaxed to the purpose of paralysis — it is completely regular, however when somebody is abruptly woke up, they could quickly discover themselves unable to maneuver. According to the National Institute of Neurological Disorders and Stroke, this (terrifying) feeling often lasts just some minutes.
According to the Division of Sleep Medicine at Harvard Medical School, cataplexy happens in nearly half of individuals with narcolepsy. Much like sleep paralysis, it is characterised by a sudden, momentary lack of muscle tone, however their causes are completely totally different. Cataplexy happens when somebody is awake, and it is triggered by robust, often optimistic feelings like laughter.
Finally, narcolepsy is often accompanied by hallucinations throughout a sleep “attack.” Referred to as “hypnogagic” when somebody is falling asleep and “hypnopomipic” after they’re waking up, the National Sleep Foundation studies that these hallucinations are typically visible and will incorporate the encompassing surroundings. According to Dr. Pavlova, these hallucinations are primarily “dreaming when you’re awake,” and a few sufferers could even have issue understanding after they’ve fallen asleep.
