    Narcolepsy is characterized by cataplexy and excessive daytime sleepiness due to the loss of hypocretin neurons in the hypothalamus.

  • 2

    The disorder is influenced by genetic predisposition and environmental factors leading to immune-mediated damage of HCRT neurons.

  • 3

    Narcolepsy is categorized into type 1 (NT1) with cataplexy and hypocretin deficiency, and type 2 (NT2) without cataplexy.

  • 4

    The HLA-DQB1*06:02 allele is significantly associated with NT1, found in up to 95% of affected individuals.

  • 5

    Understanding the immune response and neural circuitry alterations may help identify diagnostic biomarkers and therapeutic targets for narcolepsy.
