Narcolepsy, particularly NT1, is associated with hypocretin (orexin-A) deficiency due to the loss of hypothalamic orexinergic neurons and leads to irresistible attacks of sleep, cataplexy, hypnagogic hallucinations, and sleep paralysis, with symptoms beginning as early as ten years of age4,5. This evidence concerns the gene HCRT and Cataplexy.
