Understanding Vestibular Neuritis: Causes, Symptoms, and Treatment

Introduction

Vestibular neuritis is a condition that affects the inner ear and disrupts balance and spatial orientation. It is caused by inflammation of the vestibular nerve, which transmits signals from the inner ear to the brain to help maintain balance. While this condition is not life-threatening, it can be highly distressing and impact daily activities.

In this article, we’ll explore the causes, symptoms, diagnosis, and treatment options for vestibular neuritis.

What Causes Vestibular Neuritis?

Vestibular neuritis is often triggered by a viral infection, similar to those causing the common cold or flu. It can occur due to:

• Viral Infections: Respiratory viruses, herpes simplex virus, or gastrointestinal infections can cause inflammation in the vestibular nerve.
• Autoimmune Reactions: In some cases, the body’s immune system mistakenly attacks the vestibular nerve.
• Bacterial Infections (Rare): Although uncommon, bacterial infections can also lead to inner ear inflammation.

Symptoms of Vestibular Neuritis

The main symptoms of vestibular neuritis include:

• Severe Vertigo: A sudden spinning sensation that can last for hours or days.
• Dizziness and Imbalance: Difficulty maintaining balance, especially when standing or walking.
• Nausea and Vomiting: Due to severe dizziness, nausea is common.
• Nystagmus: Involuntary eye movements that can make it difficult to focus.
• No Hearing Loss: Unlike labyrinthitis, vestibular neuritis does not typically affect hearing.

Diagnosis of Vestibular Neuritis

A doctor will diagnose vestibular neuritis based on medical history, symptoms, and physical examination. Some common diagnostic methods include:

• Head Impulse Test (HIT): To assess the function of the vestibular system.
• Electronystagmography (ENG) or Videonystagmography (VNG): To detect abnormal eye movements.
• MRI or CT Scan: To rule out other conditions like stroke or brain tumors.

Treatment and Recovery

There is no specific cure for vestibular neuritis, but treatment focuses on relieving symptoms and promoting recovery:

Medications

• Anti-nausea drugs (e.g., meclizine, promethazine): To manage nausea and vomiting.
• Corticosteroids (e.g., prednisone): To reduce inflammation of the vestibular nerve.
• Antiviral medications: If a viral infection is suspected.
• Benzodiazepines (e.g., diazepam, lorazepam): To ease severe vertigo (short-term use only).

Vestibular Rehabilitation Therapy (VRT)

VRT involves exercises designed to help the brain compensate for the loss of vestibular function. Common exercises include:

• Gaze stabilization exercises to improve focus.
• Balance training to enhance stability.
• Head movement exercises to reduce dizziness.

Home Care and Lifestyle Tips

• Rest during acute attacks but gradually resume activities.
• Stay hydrated and avoid caffeine, alcohol, and smoking, which can worsen symptoms.
• Use support (such as a cane) if balance is significantly impaired.

Prognosis and Recovery Time

Most people recover within a few weeks, though some may experience lingering dizziness for months. In rare cases, chronic vestibular dysfunction may develop, requiring ongoing rehabilitation.

Vestibular neuritis can be a distressing condition, but with proper treatment and rehabilitation, most people regain their balance and return to normal activities. If you experience persistent vertigo or balance problems, seek medical attention for a proper diagnosis and management plan.
