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 78-year-old woman whose family describes her as sharp and fully independent until three days ago developed fever and a urinary infection, then became unable to hold a conversation, disoriented to place, and saw strangers in her room, with symptoms worsening at night and easing by midmorning. There is no history of prior memory decline, tremor, rigidity, or dream enactment, and her attention and orientation clearly improve within days of starting antibiotics.
Which fits better?
ADelirium
BMajor Neurocognitive Disorder with Lewy Bodies
