Every Duel you missed
Today's Duel is free. Plus opens every one before it: five quick rounds each, choosing the better fit between two diagnoses and the detail that settles it.
Round 1 of 5
A 26-year-old graduate student reports 8 months of sleeping 10 to 11 hours nightly without feeling refreshed, taking 2-hour unrefreshing naps at least four days a week, and needing several alarms and still feeling groggy after waking, which has caused her to fail two courses. She denies episodes of muscle weakness triggered by laughter, sleep paralysis, or vivid images at sleep onset, takes no sedating substances, and testing shows no sleep apnea, a nocturnal REM latency of 85 minutes, an MSLT mean sleep latency of 7 minutes with only one sleep-onset REM period, and normal CSF hypocretin-1.
Which fits better?
