Narcolepsy with cataplexy masked by the use of nicotine.

This report describes a case of narcolepsy with cataplexy masked by the chronic use of cigarettes and nicotine patches. It has been described that narcoleptic smokers report relief of symptoms by smoking tobacco cigarettes. In addition, a case describing partial treatment of sleepiness using a nicotine patch in an adolescent with narcolepsy was recently reported in this journal. Our case adds to the growing literature that nicotine may be used to manage symptoms associated with narcolepsy.
