Narcolepsy is a chronic brain disorder that causes persistent daytime sleepiness and sudden, involuntary sleep episodes. It typically emerges during adolescence or early adulthood, significantly disrupting work, school, and daily routines.

Core Symptoms

  • Daytime drowsiness: Persistent, overwhelming urge to sleep.
  • Sleep attacks: Falling asleep suddenly without warning.
  • Cataplexy: Sudden muscle weakness triggered by strong emotions.
  • Sleep paralysis: Inability to move or speak when waking.
  • Hallucinations: Vivid, frightening sensory experiences during sleep transitions.
  • Disrupted nighttime sleep: Waking up frequently throughout the night.
  • Mental health impacts: Elevated risks for depression and anxiety.

Diagnosis and Tests

Medical evaluation is crucial because symptoms pose safety risks during activities like driving. Diagnosis requires an overnight polysomnography (sleep study) to monitor physiological data, followed by a multiple sleep latency test (MSLT) to evaluate daytime nap patterns.

Management and Treatment

Narcolepsy is usually treated with behaviour changes and medicines.
  • Scheduled naps: Short, timed rests throughout the day.
  • Sleep hygiene: Maintaining a strict, consistent sleep schedule.
  • Medication avoidance: Skipping over-the-counter drugs that cause drowsiness – eg allergy medications
  • Prescription medications: Stimulants to promote wakefulness and REM sleep-suppressing drugs for cataplexy.
  • Mental health support: Utilizing counselling to navigate social stigma and emotional distress. Other people who do not understand the condition might treat you as if you are lazy or accuse you of avoiding things. All this can be hard to cope with, so it can help to have someone to talk to.
