Neurology clinical presentation

Dizziness: Clinical Presentation

Dizziness is a high-yield neurology presentation. Learners should reason from acuity and pattern recognition to a prioritized differential, targeted investigations, and first safe management steps.

Clinical Presentation

  • focal neurologic signs
  • new severe headache
  • inability to walk
  • vertical nystagmus
  • chest pain/syncope

Red Flags And Exam Traps

Red flags

Flashcards

  • What is the first safety screen in dizziness?focal neurologic signs; new severe headache; inability to walk
  • Name three high-yield causes of dizziness.BPPV; vestibular neuritis; stroke/TIA
  • Which investigation anchors the initial dizziness workup?timing-trigger history

Practice Questions And Cases

A learner is evaluating a patient with dizziness. Which finding should most strongly shift the next step toward urgent escalation?

Create a problem representation, rank the differential, choose the first investigation, and state the immediate management priority.
