Mechanism only. This course draws its line against Clinical Medicine and Surgery at pathophysiology against management, and this lecture tests that line — the epistaxis table has a management column sitting right beside the pathophysiology, and not one question here is built on it. The vascular source and the etiology are pathophysiology; what you do about it belongs to the other course. Vertigo carries extra weight. The lecturer put it plainly: “on my board exams, a third of my neurology questions were vertigo related. So know this, know these things.” The four peripheral causes are separated here on the axes that actually distinguish them — how long the vertigo lasts, whether hearing goes with it, and whether a viral infection came first.
