How is vestibular neuritis diagnosed

Vestibular neuritis is diagnosed clinically, from a single prolonged episode of severe vertigo lasting days, with nausea and unsteadiness but without hearing loss or other neurological features. The critical task is distinguishing it from a stroke. A cerebellar or brainstem stroke can present with isolated vertigo, so specific examination of eye movements is what separates the two.

Quick answer

Vestibular neuritis is diagnosed clinically, from a single prolonged episode of severe vertigo lasting days, with nausea and unsteadiness but without hearing loss or other neurological features. The critical task is distinguishing it from a stroke. A cerebellar or brainstem stroke can present with isolated vertigo, so specific examination of eye movements is what separates the two.

The typical presentation

Sudden onset of severe continuous vertigo, usually developing over hours, accompanied by nausea, vomiting and marked unsteadiness. It is a single episode rather than a recurrent pattern, and the worst of it lasts days before gradually improving over weeks. Hearing is not affected, which distinguishes it from labyrinthitis where hearing loss accompanies the vertigo. Head movement makes it dramatically worse, so people lie very still.

The examination that separates it from stroke

This is the part that matters most, because a stroke in the cerebellum or brainstem can present with isolated vertigo and looks similar from the outside. Specific bedside examination of eye movements is what distinguishes them, assessing the pattern of nystagmus, whether the eyes realign correctly when the head is turned, and whether there is vertical misalignment. Features that point towards a central cause include the inability to walk unaided, nystagmus that changes direction with gaze, new deafness, double vision, or any weakness or speech disturbance.

When imaging is needed and what recovery looks like

Imaging is arranged where central features are present, where vascular risk factors are significant, or where the examination is not reassuring, and it is performed externally. Ordinary CT is poor at detecting posterior circulation stroke, so MRI is generally the appropriate study. Recovery relies on central compensation and is helped considerably by vestibular rehabilitation; prolonged use of vestibular suppressant medication delays it, which is why those drugs are used briefly rather than continuously.

About this practice

Clinical Neurology Specialists has been physician-owned since 1998, when Leo Germin, M.D., FAANEM founded it. Five board-certified neurologists and four advanced practice providers see patients at the Las Vegas and Henderson offices, each with its own AANEM-accredited electrodiagnostic laboratory.

Clinical Neurology Specialists is an adult outpatient neurology practice for patients 18 and older. The practice performs no surgery and operates no imaging suite, infusion suite or interventional pain programme, and provides no emergency or inpatient care.

Emergency & crisis resources: Clinical Neurology Specialists is not an emergency service. For stroke symptoms, a seizure lasting more than five minutes or any medical emergency, call 911 or go to the nearest emergency room. For a mental health crisis, call or text 988 (Suicide & Crisis Lifeline).

Frequently asked

Questions about how is vestibular neuritis diagnosed

How is vestibular neuritis diagnosed?
Clinically, from a single prolonged episode of severe vertigo lasting days with nausea and unsteadiness, without hearing loss or other neurological features, supported by specific bedside examination of eye movements. The critical task is excluding a stroke. It is a single prolonged episode rather than a recurrent pattern, which is one of the features separating it from vestibular migraine and Meniere's disease.
How is it told apart from a stroke?
By specific examination of eye movements, since a cerebellar or brainstem stroke can present with isolated vertigo. Concerning features include being unable to walk unaided, nystagmus changing direction with gaze, new deafness, double vision, weakness or speech disturbance. Any of those needs emergency assessment.
How long does it take to recover?
The worst lasts days, with gradual improvement over weeks as the brain compensates. Recovery depends on that central compensation rather than the nerve healing completely, which is why staying active and vestibular rehabilitation help more than rest does. Vestibular rehabilitation helps considerably, and moving rather than resting is what drives the compensation the recovery depends on.
Why should I not keep taking anti-dizziness tablets?
Because vestibular suppressants interfere with the brain's compensation and prolong recovery when used beyond the first few days. They are genuinely useful for severe early nausea and vomiting, then become counterproductive, which is why the course is deliberately short. They are genuinely useful for severe nausea and vomiting in the first days, then become counterproductive, which is why the course is deliberately short.
Is my hearing affected?
Not in vestibular neuritis. If hearing loss accompanies the vertigo, the condition is labyrinthitis rather than vestibular neuritis, and sudden hearing loss alongside vertigo needs urgent assessment in its own right rather than being attributed to the balance problem. Sudden hearing loss alongside vertigo is a red flag in its own right and should not be attributed to the balance problem without assessment.
