Vestibular neuritis causes sudden, severe vertigo that can last for days and leave lingering imbalance. This guide explains the symptoms, causes and recovery process, along with treatment options in the UK to support faster and more complete rehabilitation.
If you have woken up with the room spinning, can barely lift your head off the pillow, and someone has just told you it might be vestibular neuritis (or the term labyrinthitis can also be used), the first thing worth knowing is that this is most likely an inner ear problem. But it is genuinely one of the most disabling things an inner ear can do, and the recovery afterwards is rarely as quick as people hope. In a certain proportion of cases, especially with other medical problems, a small stroke of the part of the brain known as the cerebellum may also present similarly. This guide walks through what vestibular neuritis is, how it is diagnosed in the UK, what treatment looks like, and what to do if recovery stalls.
What Is Vestibular Neuritis?
Vestibular neuritis is inflammation of the vestibular nerve. This is the nerve that carries balance signals from the inner ear to the brain. When the nerve becomes inflamed, the balance information from one ear is suddenly reduced or lost. The brain then receives wildly conflicting signals from the two sides, and the result is sudden, severe spinning vertigo.
The condition affects only the balance nerve, not hearing. This is the single most useful thing to know if you are trying to work out what you have. If your hearing is unchanged and you have no new ringing in the ears, vestibular neuritis is the more likely diagnosis. If hearing is affected too, the more likely diagnosis is labyrinthitis, which involves both the balance and hearing parts of the inner ear.
You may also see vestibular neuritis called vestibular neuronitis or, more recently in specialist literature, acute unilateral vestibulopathy. All three names describe the same condition.
The Two Phases of Vestibular Neuritis
Vestibular neuritis tends to unfold in two stages. Knowing which stage you are in often makes the experience less frightening.
The acute phase lasts from about two days to a week. Spinning is constant and severe. Most people are unable to walk without help, vomit repeatedly, and find that any head movement makes everything worse. The body tends to tip towards the affected side. Lying still in a darkened room is, for most people, the only tolerable position.
The post-acute phase then takes over. The intense spinning eases, but the brain has to learn to manage with reduced input from one ear. This relearning is called vestibular compensation, and it usually takes weeks to months. How well it goes depends a lot on what you do in this phase. Gentle, graded movement helps. Staying still hinders.
Who Gets Vestibular Neuritis?
Vestibular neuritis can happen at any age. The estimated annual incidence is between 3.5 and 15.5 cases per 100,000 people. The mean age at onset in one prospective study was 52 years, with cases ranging from 20 to 86. It most commonly affects people in their 30s to 60s, and it affects men and women in roughly equal numbers.
In specialist vertigo clinics, vestibular neuritis accounts for around 1 in 14 patients. In A&E, it accounts for around 1 in 17 dizziness presentations, and a further 1 in 5 people leave with no specific diagnosis at all – some of whom probably had vestibular neuritis that was never confirmed.
It is the third most common inner ear cause of vertigo, after BPPV and Ménière’s disease.
What Causes Vestibular Neuritis?
The honest answer is that researchers are still working it out. The most widely supported explanation is a viral one. The likely culprit is reactivation of herpes simplex virus type 1 (HSV-1), the same virus that causes cold sores, lying dormant inside the balance nerve.
Studies of donor tissue have found HSV-1 DNA in around 6 in 10 vestibular nerve ganglia. These are the clusters of nerve cells where the virus can lie dormant for years. When it reactivates in the balance nerve, the swelling it triggers disrupts how the nerve fires.
A recent viral illness – usually a cold, flu or sore throat – is reported by around 4 to 5 in every 10 people who go on to develop vestibular neuritis. Other related viruses include Epstein-Barr (which causes glandular fever), cytomegalovirus, parainfluenza and influenza.
Other Possible Causes
A virus is not the only explanation. In older patients or those with cardiovascular risk factors, a small drop in blood flow to the artery that supplies the inner ear can produce the same set of symptoms. Newer research is also looking at an immune-system component in some cases.
There is one thing about the anatomy that matters. The upper branch of the balance nerve is affected in the vast majority of cases. The likely reason is that the bony channel it runs through is narrower than the channel for the lower branch, which makes it more vulnerable to swelling.
What the Symptoms Feel Like
The hallmark of vestibular neuritis is sudden, severe spinning vertigo that starts abruptly and stays for more than 24 hours. This is different from BPPV, where the spins are brief and triggered by position changes. However BPPV can commonly occur at the same time as vestibular neuritis. It is also different from Ménière’s disease, where attacks can be accompanied by other audiological symptoms. With vestibular neuritis, the vertigo is constant during the acute phase. It does not come and go with movement. Movement just makes it worse. First attack of Meniere’s disease can also present similarly.
Common symptoms during the acute phase:
- Intense spinning vertigo lasting days, not seconds
- Severe nausea and vomiting, often needing medication
- Involuntary flickering eye movements (nystagmus)
- Inability to stand or walk without support
- A tendency to lean or fall towards one side
- Every symptom worsens with head movement
Hearing stays normal throughout. No tinnitus, no hearing loss, no fullness or pressure in the ear. If any of those are present, the diagnosis is more likely labyrinthitis or another condition such as Meniere’s disease or a stroke and these require urgent evaluation and MRI scan as an emergency.
Symptoms that need urgent assessment
Not every sudden vertigo is vestibular neuritis. A small but important number of people who present this way are actually having a stroke. The stroke usually affects the cerebellum or brainstem, which can look very similar to vestibular neuritis in the first few hours. The following should prompt immediate medical attention – call 999 or go straight to A&E:
- A new, severe headache alongside the vertigo
- Double vision, drooping of the face, or difficulty swallowing
- Weakness or clumsiness in an arm or leg
- Slurred speech or sudden vision changes
- Sudden hearing loss in one ear
There is also one clinical sign that doctors look for. In vestibular neuritis, a bedside examination called the head impulse test is almost always abnormal on the affected side. If it comes back normal in someone with severe ongoing vertigo, that is a red flag for a brain cause, not an inner ear one.
How Vestibular Neuritis Is Diagnosed
Vestibular neuritis is diagnosed clinically. That means it is diagnosed from the story of how the vertigo started, how long it has lasted, what your hearing is doing, and what your eye movements show. Brain MRI is usually normal, and is done to rule out stroke or other causes rather than to prove vestibular neuritis is what you have. Blood tests are performed to investigate for infectious, viral or autoimmune causes.
In an acute setting, doctors often use a three-part bedside examination called HINTS, which checks specific eye-movement patterns. It is one of the best tools for distinguishing an inner ear cause of sudden vertigo from a brain cause.
In a specialist vestibular function testing appointment, additional tests build a much clearer picture of how badly the balance nerve has been affected and which branch is involved:
- Video head impulse testing (vHIT) – measures how well the eyes stay locked on a target during a quick head movement. Identifies which canals are affected.
- Caloric testing – uses warm and cool air or water in the ear canal to measure the response from each side. A key test for assessing how much function has been lost.
- Vestibular evoked myogenic potentials (VEMPs) – sound-based tests that help identify whether the upper or lower branch of the nerve is involved.
- Videonystagmography (VNG) – assess the eye movements and their connections to the brain to elicit patterns that would be consistent with a diagnosis of vestibular neuritis or help to identify a stroke.
These tests help us measure, objectively, how much damage there has been and what the prognosis for recovery is. That sometimes differs from how a patient feels.
How Vestibular Neuritis Is Treated in the UK
Treatment falls into three areas: managing the acute attack, supporting nerve recovery, and rehabilitation to help the brain compensate.
Managing the acute phase
In the first few days, the priority is controlling the nausea and vomiting so you can drink, eat and start to move. Anti-sickness medications and short-term balance-suppressing drugs (such as prochlorperazine or cinnarizine) are useful here. They are short-term tools.
This is important: balance-suppressing medication should not be continued beyond the first few days. It is well established in the research that long-term use slows the brain’s recovery process. The NHS and most specialist services advise stopping these once the acute sickness has settled, even if you still feel unsteady. Staying on them for weeks is one of the most common reasons recovery stalls.
Medications - what the research shows
Antiviral medication on its own did not improve outcomes. Adding it to steroids gave no extra benefit.
A separate body of research has shown that without any treatment, only about a third of patients recover enough for their balance nerve test to return to normal.
A 2021 systematic review confirmed short-term benefit on objective balance measures, while noting that evidence for long-term functional recovery (how someone actually feels) is more limited.
Steroids for vestibular neuritis are not routinely prescribed in every NHS setting. If you are seen privately in a specialist clinic within the first 72 hours, this is a conversation worth having early. Treatment decisions should be made on a case-by-case basis, and there are situations where steroids are not appropriate, including poorly controlled diabetes and certain infections.
Vestibular rehabilitation
Vestibular rehabilitation is the foundation of recovery from vestibular neuritis. It should start as soon as the acute sickness has eased, usually within the first week and sometimes sooner.
The exercises help the brain learn to use the remaining balance input from the unaffected side, and recalibrate the connections that control eye-head coordination. A typical programme includes:
- Eye stability exercises (gaze stabilisation)
- Standing and walking balance training
- Graded exposure to head movement
- Exercises that gradually rebuild tolerance to busy visual environments
Starting rehabilitation early produces better outcomes. Younger people tend to recover more fully on objective tests, but meaningful improvement is possible at any age. In our clinic, the patients who recover fastest are usually the ones who push through the first uncomfortable week of exercises. The single biggest predictor of poor recovery is not doing the exercises, usually because they make symptoms briefly worse and that puts people off. They are meant to. That is how the brain learns.
Recovery and What to Watch For
Most people see significant improvement within one to three weeks. The severe spinning settles as the inflammation resolves, and the brain begins to adjust. Some residual unsteadiness, motion sensitivity or light-headedness can persist for weeks or months, particularly in busy visual environments, on escalators, or in supermarkets. These individuals would benefit from early assessment by an Audiovestibular Medicine Doctor.
Some people are left with a measurable, lasting reduction in balance nerve function on the affected side, even when they feel completely well. The brain has compensated. This is why feeling fully recovered is possible while objective tests still show a difference.
Both complications are worth being aware of because both are common and treatable.
PPPD after vestibular neuritis
Studies suggest that up to 1 in 4 people who have had a vestibular disorder may go on to develop persistent postural-perceptual dizziness (PPPD) – a condition where a constant low-level dizziness continues long after the original nerve problem has resolved.
The risk goes up if a person stays still out of fear of triggering symptoms, or if rehabilitation is never started or never completed. The dizziness in PPPD is real, but the mechanism is in how the brain processes balance information, not in ongoing damage to the nerve. It responds well to specific treatment, but it needs to be recognised. People who are still struggling with daily dizziness six weeks after the initial attack should be assessed for it.
BPPV after vestibular neuritis
BPPV causes brief spins triggered by rolling over in bed, looking up, or bending down. It can develop in the weeks after vestibular neuritis. The thinking is that the same inflammation that affected the nerve can also dislodge the tiny calcium crystals that sit inside the inner ear’s balance canals. If you start having sudden, brief positional spins after recovering from the main attack, this is what to mention.
BPPV is straightforward to treat with repositioning manoeuvres such as the Epley, and it is a fixable problem layered on top of the vestibular neuritis.
When to See a Specialist
As with any vestibular condition, early specialist audiovestibular physician input is worth considering to confirm the diagnosis or when:
- The diagnosis is uncertain, or hearing change suggests labyrinthitis or another condition
- Symptoms are not improving as expected
- Red-flag features were present, and a brain or other medical causes needs to be ruled out properly
- Residual symptoms are affecting work, driving or daily confidence after the acute phase
At Harley Street Audiovestibular Clinic, our audiovestibular physicians carry out the full range of objective vestibular function testing, confirm the diagnosis, assess the degree of recovery, and identify any secondary conditions (such as PPPD or BPPV) that need separate management.
Frequently Asked Questions
How is vestibular neuritis different from labyrinthitis?
Both involve inner ear inflammation, but they affect different parts. Vestibular neuritis affects only the balance nerve, so hearing stays normal. Labyrinthitis affects both the balance nerve and the hearing nerve, producing tinnitus, hearing loss or both alongside the vertigo. Sudden severe vertigo with no hearing change is more likely to be vestibular neuritis.
Is vestibular neuritis contagious?
No. Although it is linked to HSV-1 reactivation, the virus is not being shed in the way it is during an active cold sore. The reactivation happens deep in the nerve and cannot be passed on.
Will my balance fully recover?
Many people do regain full functional capacity, especially with early rehabilitation. Some people are left with a measurable reduction on the affected side that does not show up in everyday life because the brain has compensated. Overall, the prognosis with appropriate management is good. Hence it is worth considering early specialist vestibular physiotherapy input with the team at Harley Street Audiovestibular Clinic even if you appear to be improving.
How long does vestibular neuritis last?
The acute phase, when the spinning is severe and constant, typically lasts two days to a week. Background unsteadiness and motion sensitivity can continue for weeks. If symptoms have not resolved after a few weeks,, that suggests either an alternate diagnosis, incomplete recovery or a secondary condition such as PPPD or BPPV, and is worth a specialist review.
Can I drive with vestibular neuritis?
No driving during the acute phase. The DVLA’s medical guidelines require that any condition causing sudden disabling giddiness must be reported, and you must not drive until your doctor confirms it is safe. Most people return to driving once the acute spinning has settled and head movements no longer trigger significant symptoms. If in doubt, ask your GP or specialist before getting back behind the wheel.
When should I see a specialist for vestibular neuritis in the UK?
Specialist assessment is worth considering if:
- The diagnosis is uncertain
- Symptoms are not improving as expected
- Red-flag features were present at the start
- Residual symptoms are affecting daily life, work or confidence after the acute phase has passed
