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 27-year-old graphic designer reports sleeping 10 to 11 hours nightly for the past 8 months yet waking unrefreshed, and she dozes off at her desk at least four days a week, which has led to missed deadlines and a formal warning. Her roommate has never heard her snore, gasp, or stop breathing, and overnight polysomnography shows about 2 respiratory events per hour with no significant oxygen desaturation.
Which fits better?
AHypersomnolence Disorder
BObstructive Sleep Apnea Hypopnea
