Differential DuelPlus
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 graphic designer reports 8 months of lying awake until around 3 in the morning on work nights when she goes to bed at 11 at night, then struggling to get up at 6:30 and arriving late and drowsy to morning meetings. On weekends and during a recent two-week vacation, when she slept from roughly 3 in the morning until 11, she fell asleep within minutes, slept through the night, and woke refreshed.
Which fits better?
AInsomnia Disorder
BCircadian Rhythm Sleep-Wake Disorder
