Abstract Title: 

Vitamin BDeficiency: A Rare Cause of Excessive Daytime Sleepiness.

Abstract: 

None: Excessive daytime sleepiness (EDS) is one of the leading reasons that patients present to sleep clinics. Approximately 10% to 14% of the adults report that excessive sleepiness interferes with their daily lives. Common causes of EDS include obstructive sleep apnea, sleep deprivation, circadian rhythm disorders, medication effects, psychiatric conditions especially depression, and primary hypersomnia such as narcolepsy or central idiopathic hypersomnia. Vitamin Bdeficiency is a rare cause of EDS. We are presenting a case of severe vitamin Bdeficiency as an unusual and rare cause of hypersomnia.CITATION: Khawaja I, Yingling K, Bukamur H, Abusnina W.
