Vestibular dysfunction can cause vertigo, dizziness, and imbalance 10. Learn about its causes, symptoms, and treatment options in this informative article.
Introduction
Have you ever felt dizzy or unsteady without any clear cause?
If so, you might have vestibular dysfunction, which is a problem with the inner ear and how the brain handles information from it.
Vestibular dysfunction can lead to various issues such as feeling dizzy, nauseous, unsteady, and spinning sensations. These problems can greatly affect a person’s daily life 10.
This article will discuss the reasons, signs, and ways to treat vestibular dysfunction, so you can have a better understanding of the condition and learn how to deal with it.
What is Vestibular Dysfunction?
The vestibular system helps us know where we are and how we’re moving, and it’s important for keeping our balance.
The structure is similar in both vertebrates and some invertebrates. It includes the utricle, the saccule, and three semi-circular canals with a sensory ampulla in each 1.
Hair cells with stereociliary bundles and a kinocilium detect spatial information by responding to motion and gravity through hyperpolarization or depolarization 2.
When the vestibular system is not functioning properly, people may experience feelings of dizziness, unsteadiness, difficulty maintaining balance, and abnormal walking patterns 2.
Sport-related concussions often cause vestibular dysfunction 10.
Vestibular dysfunction can have negative effects on both the quality of life and mental health, resulting in reduced physical fitness, impaired concentration, feelings of depression, and a decline in socioeconomic status 3.
Vestibular dysfunction can be caused by various factors such as aging 4, infections, autoimmune conditions, Meniere’s disease, and exposure to harmful substances 5.
In both animal studies and clinical settings, a common method of evaluating and diagnosing vestibular dysfunction is through the indirect measurement of vestibular reflexes, which help to maintain the stability of the head and eyes in relation to space 9.
Studies have shown that being exposed to lead in industrial settings can cause problems with balance, posture 6, 7, and walking speed in both children and adults 8.
Vestibular dysfunction affects 4.9% of people within a year and 7.4% of people throughout their lifetime. The risk of having this condition is higher for women, those with lower education, people over 40, those with heart problems, and those with depression 23.

Causes of Vestibular Dysfunction
Vestibular dysfunction can be caused by a variety of factors, including:
- Inner ear infections or inflammation
- Head trauma
- Aging
- Meniere’s disease
- Benign paroxysmal positional vertigo (BPPV)
- Vestibular neuritis
- Ototoxic medications
Paroxysmal positional vertigo is a disorder of the inner ear that causes short episodes of vertigo and autonomic symptoms. It is the most common cause of brief, episodic, peripheral vestibular dysfunction and accounts for at least 20% of individuals with moderate to severe dizziness/vertigo 11, 12.
The most frequently impacted groups include women and individuals who are fifty years old or older 13, 14.
Ménière’s disease is a common vestibular disorder characterized by episodes of vertigo, accompanied by hearing loss and tinnitus. It is caused by excess fluid in the inner ear, which distorts and expands the endolymph portions of the labyrinthine system. The cause of this excess fluid is unknown, but there are many proposed explanations 14.
Ménière’s disease can be caused by a blockage in the endolymphatic sac or duct, which can happen when small particles detach and clog the entrance. This is similar to what happens in BPPV 15.
Another cause can be a problem with the vestibular aqueduct, which affects the ability to regulate fluid in the ear. There may also be an immune system issue that is not well understood and could be related to allergies. Finally, there is a genetic factor, with some people inheriting the condition from their parents 15.
A family history of getting Ménière’s disease at a younger age is linked to genetics and can cause more severe symptoms in future generations. There is no specific gene marker identified yet. Migraines may also be related to Ménière’s disease, as the symptoms can be similar and a problem with blood flow may be involved in causing vertigo 16, 17,14 .
In the 1980s, a theory suggested that when a part of the inner ear called the endolymphatic sac bursts, it allows a substance called potassium-filled endolymph to enter another area called the perilymphatic space. This causes a change in the cells responsible for hearing and balance, leading to their dysfunction 18,19.
If the sac seals and the cells return to normal, but if this process happens repeatedly, it can cause damage to these cells. Trauma can also damage the inner ear, such as from a direct hit or a blast injury 20.
Vestibular neuronitis is a common cause of vertigo that is caused by inflammation in the vestibular branch of the eighth cranial nerve. It is believed to be caused by a viral or post-viral inflammatory disorder and can result in vertigo that lasts for several days 21. Labyrinthitis is a condition where inflammation affects the cochlea and results in hearing loss 22.
Symptoms of Vestibular Dysfunction
The symptoms of vestibular dysfunction can vary depending on the underlying cause and severity of the condition. Some common symptoms include:
- Vertigo (a sensation of spinning or whirling)
- Dizziness
- Imbalance or unsteadiness
- Nausea or vomiting
- Blurred vision
- Sensitivity to motion or light
- Tinnitus (ringing in the ears)
These symptoms can be mild or severe, and they may come and go or persist for long periods. Vestibular dysfunction can significantly impact a person’s quality of life, making it difficult to perform everyday activities like walking, driving, or working.
Dizziness is a frequent symptom of vestibular dysfunction, especially among individuals over 40 years old. This symptom prompts around 10 million visits to ambulatory care facilities annually and accounts for a quarter of emergency department visits.
Vestibular dysfunction is often linked to stroke and diseases that damage the protective coating around nerves. One in four people with balance problems has had a stroke.
Vestibular dysfunction increases fall risk due to vertigo and gait imbalance, which is a major cause of morbidity and mortality in patients over 70 23, 24.
Diagnosing Vestibular Dysfunction
If you are experiencing symptoms of vestibular dysfunction, it is important to see a healthcare provider for a proper diagnosis. Your provider may perform a variety of tests to assess your vestibular function, including:
- A physical exam
- Hearing tests
- Eye movement tests
- Balance tests
- Imaging tests (such as an MRI or CT scan)
Doctors may use magnetic resonance imaging (MRI), computed tomography (CT), electronystagmography (ENG), videonystagmography (VNG), vestibular-evoked myogenic potentials (VEMP), and brainstem auditory evoked potentials/brainstem auditory evoked responses/auditory brainstem responses (BAEP/BAER/ABR) to evaluate patients with vestibular dysfunction.
Due to their low yield and associated expense, not all of these tests are always necessary 25, 26, 27.
Based on the results of these tests, your healthcare provider can determine the underlying cause of your symptoms and recommend appropriate treatment options.
Treatment Options for Vestibular Dysfunction
The treatment options for vestibular dysfunction depend on the underlying cause and severity of the condition. Some common treatment options include:
- Medications (such as antihistamines or benzodiazepines) to manage symptoms
- Vestibular rehabilitation therapy (VRT) to improve balance and reduce symptoms
- Surgery (in rare cases) to repair damage to the inner ear or other structures
VRT is a type of physical therapy that focuses on improving balance and reducing dizziness by gradually exposing the patient to movements and activities that trigger their symptoms. This therapy can be highly effective for managing vestibular dysfunction, and it is often recommended as a first-line treatment.
To treat vestibular dysfunction, doctors first identify the cause.
Most patients are treated for their symptoms with drugs that prevent nausea (such as metoclopramide, ondansetron, prochlorperazine, and promethazine), drugs that reduce dizziness (such as diphenhydramine, dimenhydrinate, and meclizine), and drugs that calm the nervous system (such as alprazolam, clonazepam, diazepam, and lorazepam) 28, 29.
For balance problems caused by migraines, doctors may prescribe drugs to prevent or stop the headaches 30, 31.
If a person has autoimmune labyrinthitis or Cogan syndrome, they may be given strong corticosteroids to treat it 32.
Other types of labyrinthitis and vestibular neuritis usually go away on their own and don’t need treatment 22, 21. However, surgery may be necessary in some cases, such as if the person has Ménière disease that doesn’t respond to other treatments or if there is a growth like an acoustic neuroma causing the problem.
A common way to treat a type of vertigo that affects the back part of the inner ear is by doing a special head movement called the Epley maneuver. The patient lies down and the head is slowly turned to one side and then to the other side while keeping the body still 33.
Patients may feel dizzy and their eyes may move uncontrollably during the Dix-Hallpike maneuver. If this happens, the maneuver should be stopped until the symptoms go away. Afterwards, the patient’s head is held still while their body is turned to one side. Then, the patient is helped to sit up on the side of the exam table facing the opposite way from where they started 34.
The aim of treating Ménière’s disease is to lessen the frequency and severity of vertigo attacks, reduce hearing loss and ringing in ears, ease chronic symptoms, and minimize disability 35.
Simple lifestyle changes like avoiding triggers, limiting sodium intake (2 to 3 gm per day), caffeine, alcohol, nicotine, stress, and allergens can help achieve these goals 35.
Frequently Asked Questions
Can vestibular dysfunction be cured?
The outlook for vestibular dysfunction depends on the underlying cause and severity of the condition.
In some cases, such as BPPV, the condition may resolve on its own or with simple treatments like the Epley maneuver. In other cases, such as Meniere’s disease or vestibular neuritis, the condition may be chronic and require ongoing management.
VRT can be highly effective for managing symptoms and improving quality of life, but it may not cure the underlying condition.
Is vestibular dysfunction the same as vertigo?
Vertigo is a common symptom of vestibular dysfunction, but not all cases of vestibular dysfunction involve vertigo.
Other symptoms, such as dizziness, imbalance, and nausea, can also be present
Are there any lifestyle changes that can help manage vestibular dysfunction?
Yes, certain lifestyle changes can be helpful for managing symptoms of vestibular dysfunction, such as:
- Avoiding triggers that worsen symptoms (such as bright lights or loud noises)
- Staying hydrated
- Getting regular exercise (with your healthcare provider’s approval)
- Avoiding alcohol and caffeine
- Getting enough rest
Can vestibular dysfunction be prevented?
While it may not be possible to prevent all cases of vestibular dysfunction, certain measures can reduce the risk of some types of the condition.
For example, avoiding head trauma and taking steps to prevent falls can reduce the risk of developing vestibular dysfunction due to injury.
Additionally, managing underlying health conditions, such as high blood pressure or diabetes, can reduce the risk of developing certain types of vestibular dysfunction.
Conclusion
Vestibular dysfunction is a usual and severe issue that can affect a person’s life quality.
With the right diagnosis and treatment, most people can control their symptoms and lead a satisfying and active life.
If you have problems with your balance, it’s important to see a doctor to find out what’s wrong and get the right treatment.
