Differentiating Benign Paroxysmal Positional Vertigo (BPPV) From Vestibular Neuritis-Labyrinthitis
BENIGN PAROXYSMAL POSITIONAL VERTIGO
• Age: More common in older adults
• Hearing loss: None
• Frequency of symptoms: Episodic (occurs with certain movements of the head)
• Hallpike test: Positive usually on one side only with upbeat and torsional nystagmus and reproduction of vertigo symptoms
• Head impulse test: Negative (Note: It is advised not to administer head impulse test in a patient with a clinical history consistent with BPPV.)
• Epley maneuver: Highly effective
• Recurrence: Frequent
VESTIBULAR NEURITIS/LABYRINTHITIS
• Age: More common in younger patients
• Hearing loss: None in vestibular neuritis; hearing loss in labyrinthitis
• Frequency of symptoms: Constant
• Hallpike test: Symptoms may be worsened in head-hanging position (Note: It is advised not to administer Hallpike test in a patient with a clinical history consistent with vestibular neuritis or labyrinthitis.)
• Head impulse test: Positive (corrective saccade seen)
• Epley maneuver: Ineffective
• Recurrence: Rare (2 to 11%)
