What is the HINTS exam?

Differentiates b/w stroke and vestibular neuritis. Normal: eye stays fixed when displaced. Abnormal: suggest peripheral lesion, eye follows displacement. Move head back and forth slowly then back to center briskly. Look for catch up saccade. Reassuring HINTS exam: Unidirectional nystagmus, no vertical skew, abnormal head impulse test. Test of skew: Cover test Normal eye stays fixed when cover and uncover. Vertical movement is abnormal and suggests stroke.
