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 24-year-old student reports six months of irresistible sleep attacks several times a day, and his knees buckle and his jaw sags for a few seconds whenever he laughs hard, while he stays fully aware. Nocturnal polysomnography shows a respiratory event index of 2 per hour without desaturations, and the next-day multiple sleep latency test shows a mean sleep latency of 5 minutes with three sleep-onset REM periods.
