Epidemiology 
[edit | edit source]

BVH is an uncommon condition that is frequently misdiagnosed or underdiagnosed.[1] The reported prevalence of BVH in literature ranges from 28 to 81 per 100 000 US adults, with greater prevalence seen in women and Hispanics. [1][2][3] Individuals diagnosed with BVH are more likely to present with social, physical and functional impairments and limitations.[2] 

Etiology/Cause [edit | edit source]

BVH is often a secondary condition from a wide spectrum of causes as listed in Table 1 below. Majority of BVM cases, about 51%, are idiopathic in nature because an underlying cause cannot be identified.[3][1][4] Of the known determinants, toxic/metabolic (13-21% of cases) is the most common and an example of this is ototoxicity, where the side effect of antibiotics, particularly aminoglycoside, results in persisting deficits (BVH).[3][1][4] Other known causes may be the result of an infection (3.8-12%) such as meningitis, and encephalitis.[3][1][4]

Clinical Presentation[edit | edit source]

add text here relating to diagnostic tests for the condition

Diagnostic Procedure [edit | edit source]

Currently, there is no standardized procedure implemented for diagnosing BVH by healthcare professionals due to the challenges faced with diagnosing, as patients present with a broad spectrum of signs and symptoms (Lucieer, Telian, van de berg). However, symptoms specific to, and commonly reported by patients include ; oscillopsia (strong indicator of BVH), unsteadiness, episodic and spontaneous vertigo (Telian).

Vestibular tests performed to help diagnose BVH include:[1][3]

  • Caloric Test
  • Rotatory Chair Test
  • Head Impulse Test (HIT)
  • Vesitbular-evoked Myogenic Potentials (VEMP)
  • Dynamic Visual Acuity Test (DVA)
  • Torsion Swing Test

Other tests conducted to aid in determining the cause include:[3]

  • Cerebral imaging
  • Audiometry
  • Blood Tests

Medical Management 
[edit | edit source]


== Outcome Measures
== Outcome measures are based on the International Classification of Function Model. [5][6] Common outcome measures influencing the Body Structure and Function level in the ICF model include [5] [7]
*Dynamic Visual Acuity Test (Level 3 = recommended) *Sensory Organization Testing *Dynamic Posturography Common measures determining one’s ability to execute tasks in the Activities Classification level of the ICP model include: [6][7][8]
*Berg Balance Scale (Level 2 = reasonable to recommend) *Dynamic Gait Index *Timed Up and Go Measures that help determine participation in society include: [5][6] *The Activities-Specific Balance Scale (level 2) *Dizziness Handicap Inventory (Level 4 = Highly recommended) *Other measures for Quality of Life such as the Vestibular Disorder Activities of Daily Living On the Body Structure and Function level, additional outcome measures that can be used include:[6] *Gait Stabilization Test *Sharpened Romburg *Sensory Organization Test with Head Shake, (Modified) Clinical Test of Sensory Interaction on Balance *Visual Analogue Scale *Visual Vertigo Analogue Scale *Motion Sensitivity Quotient, and/or Vertigo Symptoms Scale Additional outcome measures for Activity/Participation include: [6]
*Five Times Sit-to-Stand *30-Second Chair Stand *Functional Reach/Modified Functional Reach *Gait Velocity (10m Walk Test) *Balance Evaluations Systems Test *Mini Balance Evaluation Systems Test *Modified Timed Up and Go with Dual Task *Disability Rating Scale *UCLA Dizziness Questionnaire *Vertigo Handicap Questionnaire *Vestibular Handicap Questionnaire *Vestibular Activities and Participation *Vestibular Rehabilitation Benefit Questionnaire .
