Narcolepsy though isn't a common disease it does affects quality of life greatly, primarily characterized by excessive daytime sleepiness (EDS), cataplexy attacks, sleep paralysis, and hypnagogic hallucinations, which affects 1/2000 individuals. Whether changes in the serum vitamin B12 levels are involved in the pathophysiological mechanism of narcolepsy remains unclear. This study findings published in Clinical Neurology and Neurosurgery says decreased serum vitamin B12 levels are independently associated with the development of narcolepsy, which illustrates the complex relationship between vitamin B12 and narcolepsy. Future studies should explore whether vitamin B12 supplementation can improve the symptoms of patients.
