What is vestibular neuritis?
Vestibular neuritis, also known as vestibular neuronitis, is a condition that affects the inner ear and the vestibular nerve, which is responsible for transmitting signals related to balance and spatial orientation to the brain. It is characterized by the sudden onset of vertigo, which is a spinning sensation or a feeling of being off-balance.
The exact cause of vestibular neuritis is not always known, but it is commonly associated with a viral infection, typically of the upper respiratory tract. The virus affects the vestibular nerve, leading to inflammation and disruption of its normal function. This inflammation interferes with the transmission of signals between the inner ear and the brain, resulting in the symptoms of vestibular neuritis.
Symptoms of vestibular neuritis often include:
● Vertigo:
A spinning sensation that can be severe and last for several days.
● Nausea and vomiting:
Due to the intense dizziness and imbalance.
● Imbalance and unsteadiness:
Difficulty walking or maintaining balance.
● Nystagmus:
Involuntary rapid eye movements, usually horizontal.
The symptoms of vestibular neuritis typically reach their peak within 24-48 hours and gradually subside over several days to weeks. However, some individuals may experience residual dizziness or imbalance for a longer period.
Diagnosis of vestibular neuritis is based on the characteristic symptoms and a thorough medical history. Additional tests, such as a hearing evaluation or electronystagmography (ENG), may be performed to rule out other possible causes and assess the function of the vestibular system.
Treatment for vestibular neuritis focuses on managing the symptoms and helping the individual recover their balance. Medications like anti-nausea drugs and vestibular suppressants may be prescribed to alleviate symptoms during the acute phase. Vestibular rehabilitation therapy, which involves specific exercises and maneuvers to promote compensation and adaptation, is often recommended to improve balance and reduce dizziness in the long term.
It's important to consult a healthcare professional if you suspect you have vestibular neuritis or are experiencing severe vertigo and related symptoms, as they can provide an accurate diagnosis and appropriate treatment recommendations.
How rare is vestibular neuritis?
Vestibular neuritis is not considered to be a rare condition. It is a relatively common cause of peripheral vertigo, which is vertigo resulting from a problem in the inner ear or the vestibular nerve. While exact prevalence rates can vary across populations and studies, vestibular neuritis is estimated to affect approximately 3.5 to 15 people per 100,000 individuals per year.
Vestibular neuritis can occur at any age, but it is more commonly seen in adults between the ages of 30 and 60. It affects both men and women equally.
Although vestibular neuritis is not rare, it is often underdiagnosed or misdiagnosed initially because its symptoms can overlap with other conditions that cause vertigo, such as benign paroxysmal positional vertigo (BPPV) or Ménière's disease. Proper evaluation by a healthcare professional experienced in vestibular disorders is essential for an accurate diagnosis and appropriate management.
If you suspect you may have vestibular neuritis or are experiencing symptoms of vertigo, it is advisable to seek medical attention to determine the underlying cause and receive appropriate treatment.
What are the symptoms of vestibular neuritis?
The symptoms of vestibular neuritis typically include:
■ Vertigo:
This is the hallmark symptom of vestibular neuritis. It is a sensation of spinning or whirling, where you may feel like the room is spinning around you or that you are spinning in space. The vertigo can be severe and usually lasts for several days. It may be triggered or worsened by head movements.
■ Imbalance and unsteadiness:
Vestibular neuritis can cause a sense of imbalance and unsteadiness, making it difficult to walk or maintain stability. You may feel like you are swaying, stumbling, or have difficulty standing without support.
■ Nausea and vomiting:
The intense vertigo and imbalance associated with vestibular neuritis can lead to feelings of nausea, and in some cases, vomiting. These symptoms are often triggered by head movements or changes in body position.
■ Nystagmus:
Nystagmus is an involuntary rhythmic movement of the eyes. In vestibular neuritis, it is often characterized by rapid horizontal eye movements, which can be observed when looking closely at the person's eyes. Nystagmus may occur spontaneously or be triggered by specific head movements.
■ Dizziness and disorientation:
You may experience a general sense of dizziness or lightheadedness, feeling disconnected from your surroundings. Disorientation and difficulty concentrating may also be present.
It's important to note that the severity and duration of these symptoms can vary from person to person. In most cases, the symptoms reach their peak intensity within 24-48 hours and gradually improve over several days to weeks. However, some individuals may experience residual dizziness or imbalance for a longer period, known as post-vestibular neuritis syndrome.
If you are experiencing these symptoms or suspect you may have vestibular neuritis, it is advisable to consult a healthcare professional for an accurate diagnosis and appropriate management.
What triggers vestibular neuritis?
Vestibular neuritis is commonly triggered by a viral infection, typically of the upper respiratory tract. The most commonly implicated viruses are thought to be those from the herpesvirus family, including the varicella-zoster virus (which causes chickenpox and shingles) and the herpes simplex virus (which causes cold sores and genital herpes). However, other viruses may also be involved.
The exact mechanism by which these viruses lead to vestibular neuritis is not fully understood. It is believed that the virus enters the inner ear and causes inflammation, particularly in the vestibular nerve or the structures associated with it. This inflammation disrupts the normal functioning of the vestibular system, leading to the symptoms of vestibular neuritis.
In some cases, certain risk factors or conditions may predispose individuals to vestibular neuritis. These can include:
●Previous viral infections:
A history of recent viral infections, particularly those affecting the respiratory system, can increase the risk of developing vestibular neuritis.
● Immunocompromised state:
Individuals with weakened immune systems, such as those with HIV/AIDS or undergoing immunosuppressive therapy, may be more susceptible to developing vestibular neuritis.
● Stress:
Stressful events or periods of high stress have been associated with an increased risk of developing vestibular neuritis in some individuals, although the exact relationship is not fully understood.
● Genetic susceptibility:
There may be a genetic component that contributes to an individual's susceptibility to vestibular neuritis, but further research is needed to fully understand this aspect.
It's important to note that while viral infections are a common trigger, not everyone who experiences a viral infection will develop vestibular neuritis. The specific reasons why certain individuals are more susceptible to developing the condition are not yet fully known.
If you have concerns about vestibular neuritis or are experiencing symptoms, it is advisable to consult a healthcare professional for an accurate diagnosis and appropriate management.
Is vestibular neuritis contagious?
Vestibular neuritis itself is not contagious. The condition is not directly spread from person to person. It is caused by a viral infection, but once the infection has led to vestibular neuritis, it does not continue to spread to others.
The viral infections associated with vestibular neuritis, such as those from the herpesvirus family, are typically transmitted through respiratory droplets from an infected person. These infections, like the common cold or flu, can be contagious during the active phase of the viral illness. However, once vestibular neuritis develops as a result of the viral infection, it is not transmitted to others.
It's important to note that while vestibular neuritis itself is not contagious, the underlying viral infection that may trigger it can be. Practicing good hygiene, such as washing hands regularly, covering the mouth and nose when coughing or sneezing, and avoiding close contact with individuals who are actively ill, can help reduce the risk of viral infections.
If you or someone you know has vestibular neuritis, there is no need to isolate or avoid contact with others due to the condition itself. However, it is always a good practice to follow general hygiene measures to prevent the spread of any infectious illness.
What are the risk factors for vestibular neuritis?
While the exact cause of vestibular neuritis is not fully understood, there are certain risk factors that may increase the likelihood of developing the condition. These risk factors include:
■ Viral infections:
As mentioned earlier, vestibular neuritis is commonly associated with viral infections, particularly those affecting the upper respiratory tract. Having a recent viral infection, such as a cold or flu, can increase the risk of developing vestibular neuritis.
■ Age:
Although vestibular neuritis can affect individuals of any age, it is more commonly seen in adults between the ages of 30 and 60. The risk of developing vestibular neuritis tends to increase with age.
■ Gender:
There is no significant difference in the incidence of vestibular neuritis between genders, but some studies have suggested a slight predilection towards affecting women slightly more than men.
■ Genetic susceptibility:
There may be a genetic component that contributes to an individual's susceptibility to vestibular neuritis. Some studies have indicated that certain genetic variations may increase the risk of developing vestibular neuritis, but further research is needed to fully understand the genetic factors involved.
■ Immunocompromised state:
Individuals with weakened immune systems, such as those with HIV/AIDS or undergoing immunosuppressive therapy, may have an increased risk of developing vestibular neuritis. The immune system plays a role in fighting off viral infections, and compromised immunity may make individuals more susceptible.
It's important to note that having one or more of these risk factors does not guarantee the development of vestibular neuritis, and individuals without any of these risk factors can still be affected. Vestibular neuritis can occur spontaneously in otherwise healthy individuals as well.
If you have concerns about vestibular neuritis or believe you may be at risk, it is advisable to consult a healthcare professional for further evaluation and guidance.
What are the complications of vestibular neuritis?
Vestibular neuritis, while generally a self-limiting condition, can have several complications and effects that may impact an individual's daily life. These complications can include:
● Recurrent Vertigo:
Some individuals may experience recurrent episodes of vertigo even after the initial episode of vestibular neuritis has resolved. These recurrent episodes may be triggered by head movements or certain positions and can significantly affect a person's balance and quality of life.
● Postural Instability:
Persistent balance problems and postural instability can occur following vestibular neuritis. Individuals may have difficulty maintaining balance while walking, standing, or performing activities that require coordinated movements. This can increase the risk of falls and impact daily activities.
● Anxiety and Depression:
The sudden and intense vertigo experienced during vestibular neuritis can lead to emotional distress, anxiety, and depression. The fear of recurrent episodes of vertigo or the impact on daily functioning can contribute to psychological symptoms.
● Impact on Daily Activities:
The symptoms of vestibular neuritis, such as vertigo, dizziness, and imbalance, can significantly impact an individual's ability to carry out daily activities. Tasks such as walking, driving, working, and participating in social or recreational activities may become challenging.
● Reduced Quality of Life:
The persistent symptoms and associated complications of vestibular neuritis can reduce an individual's overall quality of life. The impact on physical, emotional, and social well-being can lead to limitations and frustration.
It's important to note that not all individuals will experience these complications, and the severity and duration of the complications can vary from person to person. Early and appropriate management, such as vestibular rehabilitation therapy, can help reduce the risk and severity of these complications.
If you have concerns about vestibular neuritis or are experiencing persistent symptoms or complications, it is advisable to consult a healthcare professional for evaluation and guidance. They can provide appropriate treatment options and help manage the impact on daily life.
How does an ENT diagnose vestibular neuritis?
An ear, nose, and throat (ENT) specialist, also known as an otolaryngologist, can diagnose vestibular neuritis based on a combination of the patient's symptoms, medical history, and a comprehensive evaluation.
The diagnostic process may involve the following:
■ Medical History:
The ENT specialist will begin by discussing the patient's symptoms and medical history. They will inquire about the nature of the dizziness or vertigo, its onset, duration, triggers, and associated symptoms. They may also ask about any recent viral infections or exposure to other risk factors.
■ Physical Examination:
A physical examination will be conducted, focusing on the ear, nose, and throat regions. The ENT specialist may examine the ear canal and eardrum to ensure there are no other underlying ear conditions that could be causing the symptoms.
■ Vestibular Function Tests:
Several tests may be performed to assess the function of the vestibular system. These tests can include:
■ Videonystagmography (VNG):
This test measures eye movements using video goggles and helps evaluate the function of the vestibular system.
■ Head Impulse Test (HIT):
This test involves the rapid rotation of the patient's head while the specialist monitors eye movements. It helps determine if there is any weakness or abnormal response in the vestibulo-ocular reflex.
■ Caloric Testing:
This test involves the introduction of warm or cold air or water into the ear canal to assess the responses of the vestibular system.
■ Hearing Evaluation:
Since some conditions affecting the inner ear can cause similar symptoms to vestibular neuritis, a hearing evaluation may be conducted to rule out other potential causes. This can involve pure-tone audiometry, speech audiometry, or tympanometry.
■ Additional Tests:
In some cases, additional tests such as magnetic resonance imaging (MRI) or blood tests may be ordered to rule out other possible causes or underlying conditions.
Based on the findings from the history, physical examination, and test results, the ENT specialist can make a diagnosis of vestibular neuritis. It's important to consult with a qualified healthcare professional, such as an ENT specialist, for an accurate diagnosis and appropriate management of vestibular neuritis.
What tests can help diagnose vestibular neuritis?
Several tests can help diagnose vestibular neuritis and differentiate it from other causes of vertigo. These tests aim to assess the function of the vestibular system and rule out other potential underlying conditions. The following tests are commonly used in the diagnostic process:
● Vestibular Function Tests:
These tests evaluate the function of the vestibular system, which includes the inner ear and the vestibular nerve. They help determine if there is any impairment or abnormality. Some common vestibular function tests include:
● Videonystagmography (VNG):
This test involves wearing special goggles equipped with infrared cameras that monitor eye movements. By tracking eye movements during specific head and body movements, it can help assess the function of the vestibular system.
● Head Impulse Test (HIT):
This test evaluates the vestibulo-ocular reflex (VOR), which is responsible for maintaining visual stability during head movements. It involves the rapid rotation of the patient's head while the eye movements are observed.
● Caloric Testing:
This test assesses the responses of the vestibular system by introducing warm or cold air or water into the ear canal. The resulting eye movements (nystagmus) are monitored and evaluated.
● Audiometry:
Since inner ear conditions can sometimes present with similar symptoms to vestibular neuritis, a hearing evaluation is often performed to rule out other potential causes. Various tests may be conducted, including pure-tone audiometry and speech audiometry, to assess hearing sensitivity and identify any hearing loss.
● Magnetic Resonance Imaging (MRI):
In certain cases, an MRI scan may be ordered to rule out other potential causes of vertigo, such as tumors or structural abnormalities in the brain or inner ear. This imaging technique provides detailed images of the head and can help identify any structural abnormalities.
It's important to note that not all of these tests are necessary for every individual with suspected vestibular neuritis. The specific tests performed may vary based on the patient's symptoms, medical history, and the healthcare provider's clinical judgment.
Consulting with a healthcare professional, such as an otolaryngologist or a neurologist, is crucial for an accurate diagnosis and appropriate management of vestibular neuritis. They can recommend the most suitable tests based on your specific case.

Vestibular neuritis vs. labyrinthitis: What’s the difference?
● Vestibular Neuritis:
Vestibular neuritis refers to the inflammation of the vestibular nerve, which is responsible for transmitting sensory information from the inner ear to the brain regarding balance and spatial orientation. In vestibular neuritis, the inflammation typically affects the vestibular nerve, leanding to symptoms such as sudden vertigo (spinning sensation), dizziness, imbalance, and sometimes nausea and vomiting. It is usually caused by a viral infection, most commonly a viral infection of the upper respiratory tract.
● Labyrinthitis:
Labyrinthitis, on the other hand, refers to inflammation of the labyrinth, which is a complex structure within the inner ear that includes the vestibular system responsible for balance and the cochlea responsible for hearing. In labyrinthitis, both the vestibular system and the cochlea can be affected. Therefore, individuals with labyrinthitis may experience symptoms of vertigo, dizziness, imbalance, as well as hearing loss, ringing in the ears (tinnitus), and sometimes ear pain. Like vestibular neuritis, labyrinthitis is often caused by a viral or bacterial infection, typically of the middle ear or respiratory tract.
In summary, the main difference between vestibular neuritis and labyrinthitis lies in the extent of inflammation within the inner ear. Vestibular neuritis primarily involves inflammation of the vestibular nerve, while labyrinthitis involves inflammation of both the vestibular system and the cochlea. However, the symptoms of both conditions, particularly the vertigo, dizziness, and imbalance, can be quite similar.
It's important to note that the diagnosis and differentiation between vestibular neuritis and labyrinthitis are often based on a clinical evaluation by a healthcare professional, including a thorough medical history, physical examination, and sometimes additional tests, such as audiometry or imaging studies, to rule out other potential causes. Treatment approaches for both conditions are similar, focusing on managing symptoms, supporting recovery, and addressing any underlying infection or inflammation.
Vestibular neuritis vs. BPPV: What’s the difference?
Vestibular neuritis and benign paroxysmal positional vertigo (BPPV) are two distinct conditions that can cause dizziness and balance problems. Here's a comparison of the two:
■ Vestibular Neuritis:
Vestibular neuritis is a condition characterized by inflammation of the vestibular nerve, which transmits sensory information from the inner ear to the brain for balance and spatial orientation. It typically presents with sudden, severe vertigo (spinning sensation) that can last for days to weeks, along with dizziness, imbalance, and sometimes nausea and vomiting. The most common cause of vestibular neuritis is a viral infection, often of the upper respiratory tract.
■ Benign Paroxysmal Positional Vertigo (BPPV):
BPPV is a condition caused by the presence of small calcium carbonate crystals (otoconia) within the inner ear, specifically in the semicircular canals, which are responsible for detecting rotational movements. The movement of these crystals within the canals disrupts the normal flow of fluid and leads to a sensation of vertigo. BPPV is typically triggered by specific head movements, such as rolling over in bed, looking up or down, or bending over. Episodes of vertigo in BPPV are usually brief, lasting seconds to minutes, and may be accompanied by a sensation of spinning or loss of balance.
Key Differences:
■ Onset and Duration:
Vestibular neuritis often has a sudden onset of severe vertigo that lasts for days to weeks, while BPPV episodes are usually shorter in duration and can be triggered by specific head movements.
■Underlying Cause:
Vestibular neuritis is primarily caused by inflammation of the vestibular nerve, usually due to a viral infection. BPPV, on the other hand, is caused by the displacement of otoconia within the inner ear.
■ Symptoms:
In addition to vertigo and dizziness, vestibular neuritis can be associated with imbalance and sometimes nausea/vomiting. BPPV primarily presents with brief episodes of vertigo triggered by head movements, without significant imbalance or nausea/vomiting.
■ Diagnosis:
The diagnosis of vestibular neuritis and BPPV is typically made based on a combination of medical history, physical examination, and specialized tests, such as the Dix-Hallpike maneuver for BPPV or vestibular function tests for vestibular neuritis.
It's important to consult with a healthcare professional for an accurate diagnosis if you experience symptoms of dizziness or vertigo. They can conduct a thorough evaluation, including a medical history and appropriate tests, to determine the underlying cause and provide appropriate management strategies tailored to your specific condition.
Can vestibular neuritis come back?
Vestibular neuritis can recur in some individuals, although it is relatively rare. Recurrence refers to the reappearance of symptoms similar to vestibular neuritis after a previous episode has resolved. While most cases of vestibular neuritis are self-limiting and resolve without recurrence, there are a few factors that may increase the risk of recurrence:
● Viral Reactivation:
Vestibular neuritis is often caused by a viral infection, and in some cases, the virus responsible for the initial episode can become reactivated, leading to a recurrence of symptoms. Viral reactivation is more likely in individuals with a weakened immune system or other factors that compromise their immune function.
● Persistent Inflammation or Residual Damage:
In some cases, the initial episode of vestibular neuritis may not fully resolve, and there may be persistent inflammation or residual damage to the vestibular nerve. This can make individuals more susceptible to experiencing recurrent bouts of symptoms.
● Underlying Conditions:
Certain underlying conditions, such as Meniere's disease or chronic sinusitis, can increase the risk of vestibular symptoms and may contribute to recurrent episodes that resemble vestibular neuritis.
● Risk Factors:
Certain lifestyle factors, such as smoking, excessive alcohol consumption, or high levels of stress, may contribute to a higher risk of vestibular symptoms and potentially increase the likelihood of recurrent episodes.
If you have previously experienced vestibular neuritis and are concerned about the possibility of recurrence, it is advisable to discuss your concerns with a healthcare professional. They can evaluate your specific case, consider any potential risk factors or underlying conditions, and provide appropriate guidance and management strategies to reduce the risk of recurrence. It's important to note that while recurrence is possible, it is not a common occurrence in most individuals who have experienced vestibular neuritis.
Can COVID-19 cause vestibular neuritis?
There have been reports of individuals experiencing vestibular symptoms, including dizziness and vertigo, as a result of COVID-19. However, it is important to note that the specific relationship between COVID-19 and vestibular neuritis is not yet fully understood, and further research is needed to establish a definitive link.
COVID-19 is caused by the SARS-CoV-2 virus, which primarily affects the respiratory system but can also involve other organs and systems, including the nervous system. Neurological symptoms, including dizziness and vertigo, have been reported in some COVID-19 patients. However, it is unclear whether these symptoms result from direct viral involvement of the vestibular system or from other mechanisms such as inflammation, immune responses, or effects on blood flow.
While vestibular symptoms associated with COVID-19 may resemble those of vestibular neuritis, it is important to consider other potential causes as well. Vestibular symptoms in COVID-19 can be part of a broader spectrum of neurological manifestations and may occur in conjunction with other symptoms such as fever, cough, loss of taste or smell, and respiratory symptoms.
If you are experiencing vestibular symptoms and have concerns about their potential connection to COVID-19, it is recommended to consult with a healthcare professional.

Conclusion:
In conclusion, vestibular neuritis is a condition characterized by inflammation of the vestibular nerve, leading to symptoms such as sudden vertigo, dizziness, and imbalance. It is typically caused by a viral infection and can result in temporary disruption of the inner ear's balance function. While vestibular neuritis is generally self-limiting and resolves within a few weeks to months, some individuals may experience recurrent episodes.
It's important to consult with a healthcare professional for an accurate diagnosis and appropriate management of vestibular neuritis or related symptoms. They can conduct a thorough evaluation, recommend specific tests if necessary, and provide guidance on treatment options, including medication, vestibular rehabilitation therapy, and self-care measures.
While the risk of recurrence is relatively low, some factors such as viral reactivation, persistent inflammation, underlying conditions, and lifestyle factors may contribute to the likelihood of recurrent episodes. However, the majority of individuals with vestibular neuritis experience a single episode and recover fully.
If you have concerns about vestibular neuritis or related symptoms, including dizziness, vertigo, or imbalance, it is advisable to seek medical attention. A healthcare professional can assess your symptoms, provide a proper diagnosis, and offer appropriate management strategies to help you manage and recover from the condition.
