Vestibular paroxysmia (VP) is thought to be the result of neurovascular cross-compression (NVCC) of the eighth cranial nerve, but a diagnostic gold standard remains elusive. To characterize clinical findings and response to treatment, these researchers reviewed the clinical records of 32 patients diagnosed with VP.
Vertigo attacks (seconds to minutes long) occurred at rest and with head turns, position change, or hyperventilation in 50% of patients, only at rest in 28%, and only with instigation in 22%. Although only 28% of patients had accompanying auditory symptoms, most had evidence of unilateral auditory or vestibular damage. All but 1 of 23 patients who underwent MRI had evidence of at least one site of NVCC. In most patients, VP respon…
