Interactive cases
10 patients, from the emergency department to the falls clinic. Pick a case, read the story, commit to an answer — then see why each option is right or wrong, and who needs to be in the room.
Case 1 · Sudden vertigo in a 68-year-old with hypertension
A 68-year-old man with hypertension and a smoking history develops sudden continuous vertigo with vomiting and severe unsteadiness — he cannot stand unaided. There is no hearing loss and no headache.
Examination & tests. Direction-changing gaze-evoked nystagmus, a normal (negative) head impulse test, and a skew deviation on cover testing. Truncal ataxia out of proportion to the vertigo. CT head normal.
Using the cases
Filter by category, choose a case, and answer before revealing — the rationale for every option, the diagnosis, the multidisciplinary plan and a link to the full chapter appear once you commit. There is no scoring; the value is in the reasoning. For the rules that recur across these cases, see the pattern-recognition pearls.
Remember: these are teaching vignettes, not real patients, and the plans are illustrative. Always confirm the diagnosis, exclude central and systemic mimics, and follow local pathways.
