- Objective: Patients with benign paroxysmal positional vertigo (BPPV) visit clinics
with typical position evoked vertigo. However, typical nystagmus are concealed
according to many factors We evaluated the demographic, clinical and
nystagmographic features of patients, who visited clinics with typical BPPV
symptoms but did not have positional test evoked nystagmus.
Methods
Among 306 patients with history of positional vertigo, we excluded 252
patients who had positional test evoked nystagmus on video Frenzel glass in
clinics, and analyzed 54 patients who did not have positional test evoked nystagmus.
We divided 54 patients into two groups; patients without subjective
vertigo in positional test and patients with subjective vertigo in positional test.
We analyzed the serial nystagmographic findings, causes, duration of disease, previous
history of medical or rehabilitation treatments, coexisting vestbular disorders,
recovery time and recurrence.
Results
Etiology, history of previous treatment, coexisting vestibular disorders
and recurrence did not differ statistically in both groups. However, the nystagmographic
features were significantly different in both groups.
Conclusion
When patient has positional test evoked vertigo, repeated positional
maneuver seemed to increase the expression of positional nystagmus.

Abstract
PDF
- Bilateral vestibulopathy (BV) is a clinical entity with impaired function of bilateral peripheral vestibular system, which is characterized by movement-induced vertigo, oscillopsia and gait unsteadiness. Among various etiologies of BV, alcohol and vitamin B deficiency has rarely been reported. We experienced a case of BV with vitamin B deficiency in a 24-year-old man who was previously exposed to alcohol. He had osillopsia and gait unsteadiness as a primary symptom, and was treated successfully with vestibular rehabilitation and vitamin supplement. Bithermal caloric test, rotatory chair test and head impulse test showed the result compatible with BV.
