Narcolepsy
Sleep pathology in adults

It affects approximately 0.02 % of the population, i.e. 2 persons per 10,000 inhabitants. It is clinically characterized by:

• Irresistible sleep attacks that culminate in a nap, usually of short duration and refreshing.
• Cataplexy: Episodes of loss of muscle tone triggered by emotions.
• Sleep paralysis and/or hallucinations at onset or end of sleep
• Interrupted and poor quality night sleep

The sleep study shows a dream of fragmented architecture. The latency test shows a mean latency < of 5 min and REM phase in two or more of the naps.
