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 52-year-old man with a long-standing, laboratory-confirmed retroviral infection on antiretroviral therapy has had 18 months of gradually slowed thinking, losing track of multistep tasks, and missed medication doses, so his sister now manages his pills and bills. He denies sadness or loss of interest, still enjoys weekend soccer, and gives sustained, consistent effort on testing, while brain MRI shows no opportunistic lesions or lymphoma and he uses no substances.
