What are the diagnosis and treatment options for vestibular (balance-related) disorders?

From the Guidelines

Vestibular disorders, including Benign Paroxysmal Positional Vertigo (BPPV), are best diagnosed through a combination of clinical history, physical examination, and specialized testing, with treatment often involving vestibular rehabilitation therapy (VRT) and repositioning maneuvers like the Epley or Semont maneuvers for BPPV. The diagnosis of vestibular disorders typically involves assessing symptoms like vertigo, dizziness, imbalance, and associated hearing changes.

Diagnosis

• Initial evaluation includes a thorough clinical history and physical examination.
• Specialized testing may involve videonystagmography (VNG), rotational chair testing, vestibular evoked myogenic potentials (VEMP), and sometimes imaging studies like MRI, as noted in 1.
• The Dix-Hallpike test and supine roll test are crucial for diagnosing BPPV, as they can provoke vertigo and nystagmus characteristic of the condition, according to 1 and 1.

Treatment

• Treatment depends on the specific condition but often includes vestibular rehabilitation therapy (VRT), which consists of customized exercises to promote central compensation and improve balance, as mentioned in 1 and 1.
• For BPPV, repositioning maneuvers like the Epley or Semont maneuvers are effective, with a high success rate, as indicated in 1 and 1.
• Medications such as meclizine, diazepam, or promethazine may provide symptomatic relief for acute vertigo but should be used short-term to avoid delaying compensation, as suggested in 1 and 1.

Management Considerations

• Clinicians should differentiate BPPV from other causes of imbalance, dizziness, and vertigo, and assess patients for factors that modify management, including impaired mobility or balance, central nervous system disorders, lack of home support, and increased risk for falling, as recommended in 1 and 1.
• Patient education regarding the impact of BPPV on safety, potential for disease recurrence, and importance of follow-up is crucial, as emphasized in 1 and 1.
• Vestibular function testing may be warranted in patients with atypical symptoms, suspected additional vestibular pathology, failed response to repositioning maneuvers, or frequent recurrences of BPPV, as discussed in 1.

From the Research

Vestibular Diagnosis

• The Dix-Hallpike test is commonly used to diagnose benign paroxysmal positional vertigo (BPPV), with an estimated sensitivity of 79% and specificity of 75% 3.
• The side-lying test is an alternative diagnostic maneuver, with an estimated sensitivity of 90% and specificity of 75% 3.
• A systematic approach to history and physical examination is essential for diagnosing vestibular disorders, including vertigo 4, 5.

Vestibular Treatment

• The Epley maneuver is a commonly used treatment for BPPV, and has been shown to be more effective than vestibular rehabilitation at 1-week follow-up 6.
• Vestibular rehabilitation is a treatment option for peripheral and central vestibular disorders, and has been shown to be effective in improving functional outcomes 7.
• Virtual reality and other technologies are being used to augment vestibular rehabilitation, and clinical practice guidelines have been developed for peripheral vestibular hypofunction and BPPV 7.

Diagnostic Challenges

• The diagnosis of vestibular disorders can be challenging due to the vague and imprecise nature of symptoms, and a systematic approach is essential 5.
• The Dix-Hallpike test is the standard diagnostic maneuver for posterior semicircular canal BPPV, but alternative tests such as the side-lying test can be used in patients who are unable to move into the Dix-Hallpike test positions 3.
