Which finding in the described stroke-risk patient most supports an acute stroke diagnosis?

The critical idea is that an acute stroke typically presents with a sudden focal neurologic deficit. Unilateral weakness or facial droop is a direct sign of a brain region losing its blood supply and producing motor impairment on one side of the body — a hallmark finding that strongly supports an acute stroke diagnosis. Chest pain, shortness of breath with wheeze, and a rapid irregular pulse are important alarms for cardiac or pulmonary problems or arrhythmias, but they do not localize to a brain event the way focal neurologic signs do. While arrhythmias can be a risk factor for stroke, they don’t by themselves confirm an acute stroke as clearly as unilateral weakness or facial droop does.
