Vertigo Symptoms: Understanding Your Dizziness Causes
Understanding the Causes of Vertigo: 5 Most Common Reasons You Are Dizzy
Vertigo is a condition that affects millions of people worldwide, causing a sensation of spinning or dizziness. It can be a disorienting and frightening experience, often leading individuals to seek answers about its causes and potential treatments. In this comprehensive guide, we'll delve into the various factors that contribute to vertigo, from inner ear issues to neurological conditions, helping you gain a deeper understanding of this complex phenomenon.
What is Vertigo?
Before we explore its causes, let's define what vertigo is. Vertigo is a type of dizziness characterized by a false sensation of movement or spinning. It differs from general dizziness or lightheadedness, as it often feels like the world around you is spinning or tilting, even when you're standing still. This sensation can be brief or prolonged, intermittent or constant, and may be accompanied by other symptoms like nausea, vomiting, or difficulty balancing.
Inner Ear Disorders: A Common Culprit
One of the primary causes of vertigo is inner ear disorders. The inner ear plays a crucial role in maintaining balance and spatial orientation. When there is a disturbance in the inner ear's function, it can lead to vertigo. Here are some common inner ear disorders associated with vertigo:
1) Benign Paroxysmal Positional Vertigo (BPPV)
BPPV is a disorder of the inner ear characterized by brief episodes of intense vertigo, often triggered by changes in head position, such as rolling over in bed, tilting the head back, or looking up. These positional changes cause dislodged calcium carbonate crystals (otoconia) in the inner ear to stimulate sensitive nerve endings, leading to vertigo episodes.
Key Features of BPPV:
Vertigo Episodes: Sudden and intense episodes of spinning sensation, typically lasting for a few seconds to a minute, triggered by specific head movements.
Positional Triggers: Vertigo in BPPV is often provoked by changes in head position relative to gravity, such as lying down, sitting up, or turning the head quickly.
Brief Duration: Unlike other vestibular disorders, vertigo episodes in BPPV are short-lived and resolve spontaneously, although they can be recurrent.
Causes and Triggers of BPPV:
The primary cause of BPPV is the displacement of otoconia, tiny calcium carbonate crystals normally present in the inner ear's utricle and saccule. Factors contributing to BPPV include:
Aging: BPPV is more common in older adults, as degenerative changes in the inner ear structures can lead to otoconia dislodgement.
Head Trauma: Injuries to the head, such as concussions or whiplash injuries, can dislodge otoconia and trigger BPPV episodes.
Inner Ear Disorders: Conditions affecting the inner ear, such as Meniere's disease or vestibular neuritis, may predispose individuals to BPPV.
Diagnosis and Treatment of BPPV:
Diagnosing BPPV involves a combination of medical history assessment, physical examination, and specialized vestibular tests, including the Dix-Hallpike maneuver and the supine roll test. These tests help identify the specific semicircular canal involved and confirm BPPV diagnosis. After diagnosis, BPPV is treated with Canalith Repositioning Maneuvers. This is the primary treatment for BPPV and involves canalith repositioning maneuvers, such as the Epley maneuver, Semont maneuver, or Brandt-Daroff exercises. These maneuvers aim to reposition dislodged otoconia back into the utricle, alleviating vertigo symptoms.
2) Meniere's Disease
Meniere's disease is a disorder of the inner ear characterized by episodes of vertigo, fluctuating hearing loss, tinnitus (ringing in the ears), and a feeling of fullness or pressure in the affected ear. It's believed to result from fluid buildup in the inner ear, leading to increased pressure and disturbances in balance.
Key Features of Meniere's Disease:
Vertigo Attacks: Sudden and intense episodes of vertigo, often accompanied by nausea, vomiting, and a feeling of spinning or whirling sensation; 20 minutes to 12 hours in duration.
Hearing Loss: Fluctuating hearing loss, usually affecting one ear initially but may progress to both ears over time. The hearing loss may improve between attacks but can worsen over time.
Tinnitus: Persistent or intermittent ringing, buzzing, hissing, or roaring sounds in the affected ear, often worsened during vertigo episodes.
Ear Fullness: A sensation of fullness, pressure, or "stuffed" feeling in the affected ear, similar to having ear congestion or fluid buildup.
Causes and Triggers of Meniere's disease:
The exact cause of Meniere's disease is not fully understood, but several factors may contribute to its development, including:
Endolymphatic Hydrops: An increase in fluid volume or pressure within the inner ear's labyrinth, leading to sensory disturbances and vestibular dysfunction.
Genetic Predisposition: Some individuals may have a genetic predisposition to Meniere's disease, with a family history of vestibular disorders or inner ear abnormalities.
Vascular Issues: Blood flow abnormalities or vascular conditions affecting the inner ear's blood vessels may play a role in Meniere's disease development.
Autoimmune Factors: Immune system dysfunction or autoimmune processes targeting the inner ear structures may contribute to inflammation and fluid imbalance.
Management and Treatment of Meniere's Disease:
Managing Meniere's disease involves a multifaceted approach aimed at reducing symptom severity, preventing attacks, and improving overall quality of life. Treatment strategies for Meniere's disease may include:
Lifestyle Modifications: Adopting a low-sodium diet, reducing caffeine and alcohol intake, managing stress, and getting adequate rest can help minimize vertigo episodes and improve overall well-being.
Medications: Prescription medications, such as diuretics (water pills), vestibular suppressants, and anti-nausea drugs, may be prescribed to alleviate vertigo symptoms during attacks or to prevent recurrences.
Vestibular Rehabilitation: Engaging in vestibular rehabilitation therapy (VRT) or balance exercises under the guidance of a trained therapist can help improve balance, reduce dizziness, and enhance vestibular function.
Intratympanic Injections: In some cases, corticosteroid injections directly into the middle ear (intratympanic injections) may be recommended to reduce inflammation and improve symptoms.
Surgical Options: In rare and severe cases of Meniere's disease that do not respond to conservative treatments, surgical interventions such as endolymphatic sac decompression, vestibular nerve section, or labyrinthectomy may be considered.
3) Vestibular Neuronitis and Labyrinthitis
Vestibular neuronitis and labyrinthitis is an inflammatory condition that affects the vestibular nerve, a crucial component of the inner ear responsible for balance and spatial orientation. The labyrinth is a complex structure responsible for detecting motion and spatial orientation, so when it becomes inflamed or infected, it can disrupt these functions, causing symptoms like dizziness, vertigo, and imbalance.
Key Features of Vestibular Neuronitis and Labyrinthitis:
Infection-Related: Labyrinthitis is often triggered by an infection, such as a viral upper respiratory infection or bacterial infection. This infection can spread to the inner ear, leading to inflammation and symptoms of dizziness.
Vertigo and Imbalance: Like vestibular neuronitis, labyrinthitis can cause severe and constant vertigo characterized by a spinning sensation for up to 72 hours. Imbalance and difficulty walking or standing steady are also common symptoms.
Hearing Loss: In some cases of labyrinthitis, especially if the infection affects the cochlea (part of the inner ear responsible for hearing), hearing loss or changes in hearing may occur. If hearing is spared the condition is called neuritis or neuronitis.
Treatment and Management of Vestibular Neuritis
Both vestibular neuronitis and labyrinthitis require medical evaluation and treatment, especially if symptoms are severe or persistent. Treatment strategies may include:
Medications: Antiviral or antibiotic medications may be prescribed to treat the underlying infection causing labyrinthitis. Medications to alleviate symptoms like vertigo and nausea may also be recommended.
Vestibular Rehabilitation: Vestibular rehabilitation therapy (VRT) is a specialized form of physical therapy designed to improve balance and reduce symptoms of dizziness and vertigo. It includes exercises and techniques to strengthen the vestibular system and promote adaptation.
Symptom Management: In addition to medications and VRT, managing symptoms like nausea and vomiting is essential. This may involve anti-nausea medications or lifestyle modifications to minimize triggers.
Rest and Recovery: Proper rest but not too much are crucial during the acute phase of vestibular neuronitis or labyrinthitis. Gradual reintroduction of daily activities as symptoms improve is recommended. Aim for walking 20 minutes total a day at minimum.
Central Causes of Vertigo
Central causes of vertigo are those starting from the brain and not the inner ear. There are many causes of central vertigo including stroke, tumor, migraine, concussion, Parkinson's disease, meningitis, and more. I will discuss the 2 most common I see in my practice: vestibular migraine and PPPD, Persistent postural perceptual dizziness.
4) Vestibular Migraines
Vestibular migraines are a type of migraine disorder that presents with vestibular symptoms, such as vertigo, dizziness, and balance disturbances, in addition to typical migraine features like headaches, nausea, and sensitivity to light and sound. This comprehensive guide aims to provide insights into vestibular migraines, including their causes, symptoms, diagnosis, and management strategies.
Key Features of Vestibular Migraines:
Vertigo Episodes: Sudden-onset episodes of vertigo or spinning sensation, lasting from a few seconds to several hours, and occurring independently or alongside migraine headaches.
Migraine Headaches: Recurrent headaches with pulsating or throbbing quality, typically on one side of the head, often preceded by aura (visual or sensory disturbances) or other prodromal symptoms.
Dizziness and Imbalance: Persistent feelings of dizziness, unsteadiness, or imbalance, even between migraine episodes, affecting daily activities and quality of life.
Nausea and Sensory Sensitivity: Nausea, vomiting, and sensitivity to light (photophobia) and sound (phonophobia) are commonly associated with vestibular migraines.
Causes and Triggers of Vestibular Migraine:
The exact cause of vestibular migraines is not fully understood, but several factors may contribute to their development and triggers, including:
Genetic Predisposition: A family history of migraines or vestibular disorders may increase the risk of developing vestibular migraines.
Neurological Sensitivity: Abnormalities in brain neurotransmitters, such as serotonin and dopamine, implicated in migraine pathophysiology and vestibular function.
Vestibular System Dysfunction: Disruption or hyperexcitability of vestibular pathways, leading to sensory mismatch, vertigo, and balance disturbances.
Environmental Triggers: Triggers like stress, hormonal changes (e.g., menstruation), certain foods (e.g., aged cheeses, processed meats), caffeine, alcohol, and sensory stimuli can precipitate vestibular migraine episodes. Keeping track of your triggers and responses is very important. Find my downloadable e-journal HERE: A Vestibular Migraine Workbook and Tracker.
Symptoms and Diagnosis of Vestibular Migraine:
Diagnosing vestibular migraines involves a thorough assessment of symptoms, medical history, and exclusion of other vestibular disorders. Key aspects of diagnosis include:
Symptom History: Detailed history of vertigo episodes, associated migraine symptoms, triggers, duration, frequency, and response to treatments.
Physical Examination: Neurological examination, assessment of balance, coordination, eye movements, and vestibular function tests to identify abnormalities.
Diagnostic Criteria: Criteria established by the International Headache Society (IHS) or Bárány Society may be used to confirm vestibular migraine diagnosis, requiring a history of migraines and vestibular symptoms.
Differential Diagnosis: Distinguishing vestibular migraines from other vestibular disorders, such as Meniere's disease, benign paroxysmal positional vertigo (BPPV), vestibular neuritis, and central vestibular disorders, through clinical evaluations and testing.
Management and Treatment of Vestibular Migraine:
Managing vestibular migraines focuses on symptom relief, prevention of episodes, and improving overall quality of life. Treatment strategies for vestibular migraines may include:
Lifestyle Modifications: Identifying and avoiding triggers, maintaining regular sleep patterns, managing stress through relaxation techniques or therapy, and adopting a balanced diet can reduce migraine frequency and severity.
Medications: Prescription medications, including migraine-specific drugs (e.g., triptans, ergotamines), preventive medications (e.g., beta-blockers, anticonvulsants, tricyclic antidepressants), and vestibular suppressants (e.g., antihistamines, benzodiazepines), may be prescribed based on symptom severity and frequency.
Vestibular Rehabilitation: Engaging in vestibular rehabilitation therapy (VRT) or balance exercises under the guidance of a trained therapist can improve balance, reduce dizziness, and enhance vestibular function over time.
Cognitive Behavioral Therapy (CBT): Incorporating CBT techniques, such as relaxation training, stress management, and cognitive restructuring, can help individuals cope with migraine-related anxiety, depression, and lifestyle adjustments.
Alternative Therapies: Some individuals may find relief from complementary and alternative therapies, such as acupuncture, biofeedback, herbal supplements (e.g., feverfew, butterbur), and dietary supplements (e.g., magnesium, riboflavin), although evidence supporting their efficacy is variable.
5) PPPD or Persistent Postural Perceptual Dizziness
Persistent Postural Perceptual Dizziness (PPPD) is a complex and often misunderstood condition that can significantly impact an individual's quality of life. Characterized by chronic dizziness and unsteadiness, PPPD requires a comprehensive understanding for effective management and treatment.
What is PPPD?
PPPD is a vestibular disorder that manifests as persistent feelings of dizziness or unsteadiness, particularly in response to upright posture or movement. Unlike acute vertigo or brief episodes of dizziness, PPPD is chronic and can last for months or even years, leading to considerable functional impairment and psychological distress.
Key Features of PPPD:
Chronic Dizziness: The hallmark feature of PPPD is persistent dizziness or unsteadiness that persists for extended periods, often worsening with certain triggers or movements.
Postural Instability: Individuals with PPPD may experience difficulties maintaining balance or feeling steady when standing or walking, leading to a heightened risk of falls or accidents.
Perceptual Disturbances: Alongside dizziness, PPPD can cause perceptual disturbances, such as visual motion sensitivity or a feeling of disconnection from the environment, further exacerbating symptoms.
Causes and Triggers of PPPD:
The exact cause of PPPD is not fully understood, but it is believed to result from a combination of vestibular, visual, and psychological factors. Triggers for PPPD can vary among individuals but often include:
Previous Vestibular Events: PPPD may develop following a previous vestibular event, such as vestibular neuritis, labyrinthitis, or benign paroxysmal positional vertigo (BPPV).
Visual Motion Sensitivity: Environments with high visual stimulation, such as crowded spaces, moving vehicles, or scrolling screens, can trigger or worsen symptoms of PPPD.
Anxiety or Stress: Psychological factors, including anxiety, stress, or panic disorders, can contribute to the development and exacerbation of PPPD symptoms.
Diagnosis and Treatment of PPPD:
Diagnosing PPPD can be challenging due to its complex nature and overlapping symptoms with other vestibular and neurological conditions. A thorough medical evaluation, including a detailed history and specialized vestibular testing, is essential for accurate diagnosis.

Key Steps in Diagnosis and Treatment of PPPD:
Medical Evaluation: A healthcare provider, often a neurologist or otolaryngologist specializing in vestibular disorders, will conduct a comprehensive assessment to rule out other potential causes of dizziness and confirm PPPD diagnosis.
Symptom Management: Treatment strategies for PPPD focus on symptom management and improving functional ability. This may include medications to alleviate dizziness, anxiety, or depression, as well as lifestyle modifications to reduce triggers.
Vestibular Rehabilitation: Vestibular rehabilitation therapy (VRT) plays a crucial role in PPPD management by addressing balance deficits, improving postural control, and promoting adaptation to sensory inputs. VRT is tailored to individual needs and may include exercises to enhance vestibular function and reduce symptom severity.
Psychological Support: Given the psychological impact of PPPD, counseling or cognitive-behavioral therapy (CBT) may be recommended to address anxiety, stress, and maladaptive behaviors associated with chronic dizziness.
Medication: Most beneficial medications are the class of drugs known as anti-depressants; like SSRI's and SNRI's. Not all patients need medication but many do, and this should be discussed with your physician. Also, it is important to know, that any medication you take does not have to be lifelong; sometimes the brain just needs a reset.
Treatment for vertigo depends on its underlying cause. It may include:
Canalith repositioning maneuvers for BPPV
Vestibular Therapy for inner ear weakness known as vestibular hypofunction
Medication to manage symptoms: vestibular suppressants, supplements, migraine medication, anti-nausea, blood pressure medications, or anti-anxiety medications based on your doctor's recommendations
Movement: light to moderate exercise daily can work the vestibular system, improve blood flow to the brain which helps with anxiety and reduces dizziness, keeps you functioning and enjoying life
Surgical interventions in some cases (e.g., for Meniere's disease or certain structural issues)
Conclusion
Vertigo is a complex condition with various possible causes, ranging from inner ear disorders to neurological conditions and other contributing factors. Understanding the underlying mechanisms of vertigo is crucial for accurate diagnosis and effective management. If you or someone you know experiences vertigo symptoms, don't hesitate to seek medical attention to determine the cause and explore appropriate treatment options. By addressing the root cause and implementing targeted interventions, individuals with vertigo can improve their quality of life and regain control over their balance and well-being.
