About the Disease

Vestibular Neuritis, also known as Vestibular Neuronitis, occurs when a viral infection triggers inflammation in the vestibular nerve. This nerve is crucial for maintaining balance, and its impairment can result in dizziness and imbalance. Common viral infections, such as a cold, flu, or sore throat, can lead to this inflammation.

Cases and Symptoms Vestibular Neuritis

  1.  Dizziness or Vertigo: Intense spinning sensations, particularly severe in the first few days.
  2.  Nausea and Vomiting: Accompanying the vertigo, these symptoms can be debilitating.
  3.  Difficulty in Focusing: Especially during head movements, making daily activities challenging.

Labyrinthitis and Vestibular Neuritis share similar characteristics. In Vestibular Neuritis, only the vestibular portion of the vestibulocochlear nerve is inflamed, affecting balance. In contrast, Labyrinthitis affects both parts of the vestibulocochlear nerve, leading to balance and hearing issues.

Cause: Viral infections trigger inflammation of the vestibular nerve, disturbing balance signals to the brain.

Symptoms: The condition causes sudden and intense vertigo, often accompanied by vomiting, nausea, and blurred vision during head movement. Symptoms can last for several days, followed by mild residual imbalance.

Comparison with Labyrinthitis: Vestibular Neuritis affects only balance and does not cause hearing loss. Labyrinthitis involves both balance and hearing nerves and can lead to hearing loss in one ear. Labyrinthitis is a medical emergency that requires early diagnosis and treatment to prevent permanent hearing loss.

Diagnosis

Diagnosis involves several tests to evaluate the function of the vestibular system:

  • Videonystagmography (VNG): Detects horizontal spontaneous nystagmus, which reduces with optic fixation.
  • Video Head Impulse Test (vHIT): Identifies deficits in the vestibulo-ocular reflex on the affected side.
  •  Subjective Visual Vertical (SVV) Test: Measures misinterpretation of the vertical plane, typically shifted to the damaged side by more than 10°.
  •  Craniocorpography (CCG): Reveals rotation to the affected side during the Unterberger test.
  •  Dynamic Visual Acuity (DVA): Assesses any reduction in visual acuity during movement.
  •  Audiogram and Impedance Measurements: Ensure no cochlear or middle ear impairment.

 

A normal neurological examination is typical, and over a few days, vestibular symptoms usually subside, reducing sensations of spinning. Neurovegetative symptoms like nausea and vomiting also reduce, although imbalance may persist for some time. If vertigo is accompanied by unusual headaches or neurological symptoms, a brain MRI is recommended to rule out central pathology.

Treatment

Treatment consists of managing the symptoms of Vestibular Neuritis and initiating vestibular rehabilitation as early as possible.

Managing Symptoms

  •  Medication: Oral drugs are prescribed to control nausea and vomiting. In cases of severe nausea, IV fluids may be administered to prevent dehydration.
  •  Vestibular Suppressants: These medications help control vertigo and dizziness but should not be used for more than three days to avoid delayed or incomplete recovery.
  •  Steroids: Used within the first five days of infection onset to reduce nerve swelling and inflammation.

Vestibular Rehabilitation
Vestibular rehabilitation aims to retrain the brain to adapt to changes in balance function, a process known as vestibular compensation. This includes evaluating and targeting specific balance functions:

  •  Vestibulospinal System: Assesses balance maintenance during standing and walking.
  • Vestibular Ocular System: Evaluates vision stabilization at rest and during head movement.
  • Posture and Center of Gravity Control

Based on the evaluation, customized vestibular rehabilitation exercises are recommended to the patient.

Balance Exercises
Balance exercises help the brain adjust to new circumstances and maintain stability despite confusing signals from the dysfunctional balance system. These exercises are tailored to the patient’s condition and progress, performed 2-3 times a day. Specific instructions on how to perform the exercises and home safety tips are provided to prevent falls. In cases where home-based exercises are ineffective, rehabilitation under a therapist’s guidance is necessary.

Vestibular Neuritis

If you are experiencing sudden vertigo, imbalance, or dizziness, NeuroEquilibrium specialists provide advanced vestibular diagnostics and rehabilitation for faster recovery.

  • Vestibular Neuritis is a viral inflammation of the balance nerve known as the vestibular nerve.
  • It causes sudden, severe vertigo, nausea, and imbalance, while hearing usually remains unaffected.
  • Early corticosteroid treatment within 24 to 72 hours may improve recovery.
  • Vestibular Rehabilitation Therapy (VRT) helps restore balance and reduce dizziness faster.
  • Most patients recover within weeks when treatment and rehabilitation begin early.

Overview of Vestibular Neuritis

Vestibular Neuritis is a specific type of inner ear disorder that causes vertigo due to inflammation of the vestibular nerve, which controls balance. It often follows viral infections such as a cold, flu, or sore throat.

Treatment 

1. Diagnosis 

Accurate diagnosis is essential to rule out central causes such as stroke and to determine the type and extent of nerve involvement.

Specialized vestibular tests used include:

  • Video Head Impulse Test (vHIT): Detects semicircular canal function and vestibular reflex deficits.
  • Videonystagmography (VNG): Differentiates between inner ear and brain-related balance disorders.
  • Vestibular Evoked Myogenic Potentials (VEMP): Identifies specific patterns of nerve dysfunction.
  • Subjective Visual Vertical (SVV): Measures how the vestibular system influences perception of vertical alignment.
  • MRI (if indicated): Performed when neurological symptoms suggest central nervous system involvement.

2. Acute Care 

Symptom control focuses on short-term relief of dizziness and nausea.

  • Medication: Antiemetics and vestibular suppressants may be prescribed for the first 24 to 72 hours to manage intense spinning and vomiting.
  • Caution: Prolonged use of these medicines should be avoided as they may delay the natural recovery process.
  • Hydration: IV fluids may be necessary if vomiting leads to dehydration.

3. Steroid Therapy 

Steroids can reduce nerve inflammation when started early.

  • Early steroid use within 24 to 72 hours of symptom onset may help improve balance nerve recovery.
  • Treatment is short-term and prescribed only after a medical evaluation of benefits and risks.
  • Self-medication should be avoided.

4. Vestibular Rehabilitation Therapy (VRT) 

VRT is the mainstay of recovery and should begin as soon as the acute symptoms such as vomiting have subsided. It consists of tailored exercises that train the brain to adjust to changes in balance signals, a process called vestibular compensation.

Benefits of Early VRT:

  • Reduces residual dizziness sooner.
  • Improves balance and eye stability.
  • Prevents chronic dizziness such as PPPD.
  • Builds confidence in movement and mobility.

Virtual Reality (VR)-Based VRT: NeuroEquilibrium’s Virtual Reality modules simulate real-life situations such as walking on uneven ground or balancing on narrow paths. This enhances precision, engagement, and faster functional improvement.

Frequently Asked Questions

How long does Vestibular Neuritis last?

Severe vertigo usually lasts for two to three days and gradually improves over two to six weeks with vestibular rehabilitation.

Steroids may be prescribed if started within the first 72 hours of symptom onset. Your doctor will decide based on your condition.

Once the nausea and vomiting settle, usually within a few days. Starting early helps the brain adapt faster.

No. BPPV causes short bursts of vertigo due to displaced inner ear crystals, while Vestibular Neuritis is nerve inflammation that causes prolonged spinning.

Recurrence is rare. Maintaining vestibular health and seeking prompt treatment for viral infections can help reduce risk.
