The HINTS exam is a cluster of three bedside clinical tests that aim to assess individuals presenting with acute-onset dizziness, vertigo, nystagmus, head motion intolerance, and nausea/vomiting, also known as acute vestibular syndrome (AVS).

A HINTS exam consistent with peripheral vertigo should have all of the following: an abnormal head impulse test (with a corrective saccade), nystagmus that does not change direction on eccentric gaze, and a negative test of skew deviation.
