HINTS Exam for Stroke in Acute Vestibular Syndrome

Head Impulse, Nystagmus, Test of Skew (HINTS). A bedside oculomotor examination to differentiate central (stroke) from peripheral (vestibular neuritis) cause of acute vestibular syndrome. More sensitive than early MRI.

Score interpretation

Central Cause — HIGH Stroke Risk

→ HINTS Central Pattern: At least one central sign (normal HIT, direction-changing nystagmus, or skew deviation). HIGH suspicion for posterior circulation stroke. Urgent MRI/DWI (note: may be false-negative <48h). Stroke team activation; admit; antiplatelet/anticoagulation per aetiology.

Peripheral Cause — Low Stroke Risk

→ HINTS Peripheral Pattern: All three peripheral signs (abnormal HIT, unidirectional nystagmus, no skew). Low probability of stroke (~0%). Consistent with vestibular neuritis. Vestibular suppressants (prochlorperazine); corticosteroids (prednisolone); Epley manoeuvre if BPPV suspected; outpatient follow-up.

Interpretation bands for the HINTS Exam. Apply clinical judgement and local guidance.
