BACKGROUND: Narcolepsy can be defined as a sleep disorder. However, whether changes in the serum vitamin B12 levels are involved in the pathophysiological mechanism of narcolepsy remains unclear. Our study aimed to assess whether vitamin B12 levels are independently related to the occurrence of narcolepsy.
METHODS: The serum folate, vitamin B12, and homocysteine levels of 40 patients with narcolepsy and 40 age- and gender-matched healthy controls (HC) were retrospectively analyzed. According to the results of the univariate logistic analysis, a multiple logistic regression model was constructed to predict the independent influencing indicators.
RESULTS: Serum folic acid and vitamin B12 levels in the narcolepsy group were significantly reduced. Moreover, through the sex subgroup, males in the narcolepsy group had lower serum vitamin B12 levels. Multivariate logistic regression revealed serum vitamin B12 to be independently associated with narcolepsy (p < 0.05; odds ratio=0.97; 95% confidence interval: 0.95-0.98).
CONCLUSION: 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.
