Narcolepsy is an incurable non-progressive disease of the central nervous system. In humans, narcolepsy causes excessive drowsiness during the day (sometimes a sleep-attack occurs), cataplexy (sudden loss of muscle tone), hallucinations, and sleep paralysis. In the horse and other mammals cataplexy is the most frequently observed symptom. ⋯ Cataplexy (which can be induced by physostigmine injection) confirms the diagnosis. Several drugs are available for the treatment of narcolepsy in humans. However there are a few data on the results of treatment of narcolepsy in the horse.
