Abstract PDF: Objectives
In vestibular neuritis (VN), the lesion preferentially affects the superior vestibular nerve because of the anatomic arrangement. It is well known that VN patients have a higher score of metabolic syndrome or a higher incidence of vertebral artery hypoplasia than controls. However, it is unclear whether the frequency of cardiovascular risk factors can affect the selective involvement of the branch of the vestibular nerve. Thus, we investigated the influence of cardiovascular risk factors on the development of total- or divisional VN. Methods: 61 patients with VN were enrolled. Video head impulse tests and caloric tests were performed to determine which vestibular divisionswere affected. The patients were divided into divisional-VN (superior or inferior) and total-VN groups. Statistical analysis of the frequency of cardiovascular risk factors was performed only in superior and total VN groups because the number of inferior VN patients was too small to be statistically analyzed. Results: Nineteen (31.1%) patients were classified as the total-VN group. In the divisional-VN group (42 patients, 65.6%), 40 were superior VN. The frequency of cardiovascular risk factors are not significantly different in superior VN and total-VN groups (All patients 50/61 [82.0%], superior-VN 36/40 [90.0%], total-VN 13/19 [68.4%]). The frequency of having more than one cardiovascular risk factor was slightly higher in the superior VN group, (13 [68.4%] vs. 36 [90.0%], p=0.062) but did not show any significant difference. Conclusions: The number of cardiovascular risk factors did not differ in superior VN patients compared to total VN patients.

Dizziness is the most common symptom in elderly patients and has been identified as a risk factor for falls. They can affect objectively the ability to achieve a stable gaze, posture, and gait. Research on the relationship between vestibular hypofunction and falls in elderly people has been rarely performed and the evidence is controversial. Because falls result from various combinations of many factors, validated tools should be used for assessment of falling. Many of the tests and numerous parameters associated with the risk of falling have already been introduced, however guidance on which test is most appropriate for use in a specific setting still lack in the medical community. Therefore, developement of comprehensive fall risk management guideline and assessment tool including physical, psychosocial, environmental factors are necessary to prevent falls in the elderly. Establishment of validity and reliability for relationship among several vestibular function test are more important to evaluate efficiently risk of falls in the dizzy patients. Also we can expect that decreasing risk of fall when conduct the developement of additional customized intervention method using verified assessment tools.
