Clinical Diagnosis of Benign Paroxysmal Positional Vertigo and Vestibular Neuritis

Author/s: 
Johns, Peter, Quinn, James

• Assess patients with vertigo for focal neurologic signs and symptoms, sustained substantial headache or neck pain, inability to stand and spontaneous vertical nystagmus.

• Perform the Dix–Hallpike test only for patients with episodes of vertigo less than 2 minutes and no nystagmus at rest.

• Perform the head impulse, nystagmus and test of skew (HINTS) plus (plus refers to a test of recent hearing loss) examination only for patients with hours or days of constant, ongoing vertigo and nystagmus at rest.
