Questions

A 35-yeаr-оld mаle pаtient presents with excessive daytime sleepiness fоr 6 mоnths. He reports occasional episodes of sudden sleepiness occurring at any time without warning. Over the past 6 months, on at least 8 occasions, he has suddenly fallen on the floor without losing wakefulness; these episodes usually occur after fits of laughter. Multiple sleep latency tests reveal a mean sleep-onset latency of 7 minutes and 3 sleep-onset random eye movement episodes during the naps. Based on the most likely diagnosis, pharmacotherapy is initiated and daytime sleepiness improves, but he still has episodes where he loses muscle control and collapses after highly emotional events. What additional treatment is most likely to be helpful?
