Narcolepsy type 1 (NT1) is a neurological disorder characterized by excessive daytime sleepiness, cataplexy, sleep paralysis, and hallucinations while awake. It results from the loss of orexin-producing neurons in the hypothalamus, leading to a deficiency of the neuropeptide orexin/hypocretin. Studies show differences in the clinical presentation of NT1 between Caucasian and African American populations, highlighting the importance of research into genetic and clinical characteristics specific to Black and North African populations.
A genetic study in these populations could identify novel genes associated with NT1 and NT2, providing crucial information for personalized diagnosis and treatment. This would fill a knowledge gap and promote more effective interventions for individuals of African descent, contributing to a better understanding of narcolepsy globally.

Age ≥ 6 years
Clinical confirmation of narcolepsy according to the criteria of the International Classification of Sleep Disorders (ICSD-3).
