[Narcolepsy type 1 and hypocretin neurons].

Narcolepsy is a neurological sleep disorder characterized by a disrupted sleep-wake cycle. The disorder is subdivided into type 1 (NT1) and type 2, where NT1 is distinguished by cataplexy and low hypocretin levels in the cerebrospinal fluid. Despite lacking indisputable evidence, the scientific consensus regarding the disease pathogenesis revolves around an autoimmune destruction of the hypocretin neurons.
