Adie (1926) first delineated narcolepsy as a separate and specific entity. It is a sleep disorder characterized by attacks of disabling daytime drowsiness and low alertness. The normal physiologic components of rapid eye movement (REM) sleep, dreaming and loss of muscle tone, are separated and also occur while the subject is awake, resulting in half-sleep dreams and episodes of skeletal muscle paralysis and atonia (cataplexy and sleep paralysis). Unlike normal sleep, that of narcolepsy often begins with REM activity and the time taken to fall asleep is shorter than normal.
In contrast to animal models, human narcolepsy is not a simple genetic disorder. Most human cases of narcolepsy are sporadic and carry a specific HLA haplotype (Peyron et al., 2000). Familial cases are the exception rather than the rule, and monozygotic twins show only partial concordance (25 to 31%) (Mignot, 1998).

MalaCards based summary : Narcolepsy 1, also known as narcolepsy-cataplexy syndrome, is related to idiopathic hypersomnia and hypersomnia, and has symptoms including excessive daytime somnolence and hallucinations, hypnagogic. An important gene associated with Narcolepsy 1 is HCRT (Hypocretin Neuropeptide Precursor), and among its related pathways/superpathways are G-protein signaling N-RAS regulation pathway and MHC class II antigen presentation. Affiliated tissues include eye, skeletal muscle and hypothalamus, and related phenotypes are hallucinations and cataplexy UniProtKB/Swiss-Prot : 73 Narcolepsy 1: Neurological disabling sleep disorder, characterized by excessive daytime sleepiness, sleep fragmentation, symptoms of abnormal rapid- eye-movement (REM) sleep, cataplexy, hypnagogic hallucinations, and sleep paralysis. Cataplexy is a sudden loss of muscle tone triggered by emotions, which is the most valuable clinical feature used to diagnose narcolepsy. Human narcolepsy is primarily a sporadically occurring disorder but familial clustering has been observed. |
