Vestibular Neuronitis: Symptoms, Causes, and Recovery in the UK

Vestibular neuronitis is a condition that affects the vestibular nerve, which connects your inner ear to your brain. This nerve is responsible for sending signals about balance and head position. When this nerve becomes inflamed, it disrupts the signals sent to the brain, resulting in a sudden, intense feeling that you or your surroundings are spinning.

In the UK, this is a relatively common cause of acute vertigo. While the symptoms can be frightening and debilitating, it is rarely a sign of a more serious underlying health problem. It is often confused with labyrinthitis; however, while both cause vertigo, labyrinthitis also involves hearing loss or tinnitus (ringing in the ears), whereas vestibular neuronitis typically only affects balance.

The onset of vestibular neuronitis is usually sudden. Most people experience a 'vertigo attack' that can last several hours or even days. Common symptoms include:

• Sudden, severe vertigo: A feeling that the room is spinning or moving.
• Nausea and vomiting: Often severe during the first 24 to 48 hours.
• Unsteadiness: Difficulty walking or standing, with a tendency to lean or fall to one side.
• Nystagmus: Involuntary, rapid eye movements that usually disappear after a few days.

Crucially, you should not experience any change in your hearing or any neurological symptoms like slurred speech or double vision. If these occur, it may indicate a different condition that requires urgent medical investigation.

Medical professionals believe that most cases of vestibular neuronitis are caused by a viral infection of the inner ear or the vestibular nerve itself. You may find that you develop vertigo shortly after recovering from a common cold, influenza, or a sore throat.

The inflammation prevents the nerve from correctly communicating balance information. Because the unaffected ear continues to send normal signals, the brain receives conflicting data, which it interprets as movement or spinning. While anyone can develop the condition, it is most frequently diagnosed in adults between the ages of 30 and 60.

The treatment of vestibular neuronitis focuses on managing symptoms during the acute phase and promoting compensation by the brain in the recovery phase.

Acute Phase (Days 1–3)

During the first few days, the priority is reducing nausea and spinning. A GP may prescribe short-term medication such as prochlorperazine or antihistamines (like cyclizine). These are known as vestibular suppressants. It is important to only use these for a few days, as using them long-term can actually slow down your brain's natural ability to compensate for the balance error.

Recovery Phase (Weeks 1–6)

As the intense spinning subsides, you may still feel lightheaded or 'off-balance' when moving your head quickly. The best treatment at this stage is to stay active. Moving your head and body tells your brain that it needs to recalibrate. If symptoms persist, a physiotherapist may recommend Vestibular Rehabilitation Therapy (VRT). These are specific exercises designed to retrain the brain to rely on other signals (like vision and touch) to maintain balance.

If you experience sudden vertigo that makes it difficult to carry out your daily activities, it is advisable to consult a healthcare professional. An online GP can help differentiate between vestibular neuronitis, labyrinthitis, and other causes of dizziness through a detailed clinical history.

You should speak to a GP if:

• Your vertigo does not improve after 48 hours.
• You are struggling to keep down fluids due to vomiting.
• You require a sick note for work due to balance issues.
• You are worried about the frequency of your dizzy spells.

A clinician can provide advice on symptom management, prescribe short-term anti-sickness medication, and guide you on the necessary steps for balance rehabilitation.

While waiting for the symptoms to pass, there are several practical steps you can take at home to manage the discomfort:

• Rest in a quiet, dark room: This reduces the sensory input your brain has to process.
• Avoid sudden movements: Move your head slowly and carefully when changing positions.
• Stay hydrated: If you are vomiting, take frequent small sips of water or use oral rehydration salts.
• Avoid triggers: Bright lights, TV screens, and reading can often make the spinning worse during the first 24 hours.
• Safety first: Do not drive or operate machinery until the vertigo has completely resolved and you feel stable on your feet.
