Abstract
Sleep paralysis (SP) is defined as a transient conscious inability to perform voluntary movements, typically arising during the transition between wakefulness and rapid eye movement (REM) sleep. Although individuals are unable to make movements during sleep paralysis, they often are able to open their eyes, are aware of their surroudings, and are capable of later providing accurate reports on events that occured during the episode.
This state often is accompanied by vivid and terrifying sensory, motor, and affective hallucinations. SP occurs as part of narcolepsy but far more commonly as an isolated phenomenon.
We report a case of video-polysomnographically documented long-lasting incomplete SP that presented as the first symptom of narcolepsy.
