Differential builder

Pick the HINTS findings you have. Get a classification, INFARCT triggers, and the most likely archetype matches ranked by fit.

Each archetype is scored against its canonical truth set: matches add to the score, contradictions subtract. The classification is the sameclassifyHints function that drives the trainer and the quiz — so the framework here is identical to what you have been practising elsewhere.

Classification

Indeterminate

Incomplete or inconsistent findings — complete all three tests and consider HINTS-plus (new hearing loss).

Closest archetype matches

Scored against each archetype's canonical HINTS truth set. Matches add to the score; contradictions subtract. Click through to the matching disease module for the clinical context.

  1. peripheral

    Vestibular neuritis

    0%

    Classic peripheral HINTS triad — reassuring in acute vestibular syndrome.

  2. peripheral

    Labyrinthitis

    0%

    Same HINTS as neuritis; hearing loss is the distinguishing feature.

  3. central

    AICA territory stroke

    0%

    May mimic peripheral if labyrinthine artery involved — hearing loss + central HINTS = AICA until proven otherwise.

  4. central

    PICA territory stroke

    0%

    Lateral medullary (Wallenberg) syndrome — central HINTS plus brainstem signs.

How to use this

This tool is a teaching aid, not a clinical algorithm. It works best as a calibration check: choose a pattern you saw at the bedside, see what archetypes match, then read the underlying disease module for the clinical context. If your bedside exam was incomplete, leave fields as "not tested" — the scoring handles missing data without penalising the underlying archetype.

HINTS-plus is included as a separate toggle because it changes management decisively: new unilateral hearing loss alongside an otherwise peripheral HINTS pattern moves the case into the central workup pathway.
