Narcolepsy​ - Diagnosis


To diagnose narcolepsy, the patient first undergoes a medical history and physical examination. This is followed by a polysomnogram (PSG) and a multiple sleep latency test (MSLT).

A polysomnogram measures the various body functions during sleep, including:

  • Nasal airflow
  • Respiratory effort
  • Blood oxygen level
  • Snoring
  • Heart rate and rhythm (ECG)
  • Electrical activity in the brain (EEG)
  • Eye and muscle movements

The multiple sleep latency test is performed in the day to assess how easily the patient falls asleep, and also the type of sleep pattern produced. It records the brain waves, heart rate, muscle activity and eye movements.

No blood test is involved in the diagnosis of narcolepsy.
