What is Vertigo

Introduction to Vertigo

Vertigo is the feeling of being unsteady or lightheaded. It’s often described as a spinning or swaying feeling, even when you’re not moving. Inner ear or brain issues can cause Vertigo, resulting in nausea or difficulty walking. Treatment depends on the underlying cause.

It is a feeling of tumbling or movement when the body is stationary. It often stems from inner ear or brain issues, disrupting the body’s balance system. Common symptoms include dizziness, nausea, and a feeling of instability. Causes range from inner ear disorders like benign paroxysmal positional Vertigo (BPPV) to more severe conditions like Meniere’s disease or vestibular migraine.

Historical Perspective

It is often described as spinning or dizziness and has been recognized for centuries. Here’s a historical perspective on Vertigo:

• Ancient Times: Ancient medical texts from Greece, Rome, and Egypt mention sensations of dizziness and spinning, attributing these symptoms to imbalances in bodily humor or fluids.
• Middle Ages: During this era, Vertigo was often viewed through a lens of mysticism, believed to be a divine punishment or a sign of demonic influence. Treatments included spiritual remedies like prayers, exorcisms, and herbal concoctions.
• Renaissance: The Renaissance marked a shift toward empirical medicine. Physicians began acknowledging Vertigo as a physical ailment rather than a supernatural phenomenon. Revising understanding and treatment methods is still necessary.
• 18th and 19th Centuries: As modern medicine advanced, we better understood the physiological causes behind Vertigo. Researchers identified specific inner ear disorders such as Ménière’s disease as causes, yet treatment options remained limited and often ineffective.
• 20th Century: The 20th century witnessed significant progress in diagnosing and treating Vertigo. The introduction of technologies like electronystagmography (ENG) and videonystagmography (VNG) improved the evaluation of vestibular function. Research revealed the vestibular system’s role in spatial orientation.
• Contemporary Era: In recent decades, research into Vertigo has accelerated. Advanced diagnostic tools like vestibular evoked myogenic potentials (VEMP) testing and rotary chair testing have enhanced our ability to diagnose vestibular disorders. Treatment options, including vestibular rehabilitation therapy (VRT), medications, and surgical interventions, have expanded, offering relief to many sufferers.

Physiology of Vertigo

Problems in the inner ear or the brain commonly cause Vertigo. Here’s a detailed look at the physiology of Vertigo:

• Vestibular System Dysfunction: It often originates from disturbances in the vestibular system, including inner ear structures such as the semicircular canals, otolith organs (utricle and saccule), and the vestibular nerve. These structures detect changes in head position and motion, and dysfunction can lead to Vertigo.
• Central Nervous System Processing: The brainstem and cerebellum play crucial roles in processing sensory information from the vestibular system. When this information is inaccurately processed or misinterpreted, it can result in the sensation of spinning or dizziness associated with Vertigo.
• Visual and Proprioceptive Input Integration: The brain integrates visual input and proprioceptive signals (information from muscles and joints about body position). Discrepancies between these inputs and vestibular signals can cause Vertigo as the brain struggles to reconcile conflicting information.
• Peripheral Vestibular Disorders: Conditions such as benign paroxysmal positional Vertigo (BPPV), Meniere’s disease, and vestibular neuritis directly affect the inner ear. BPPV involves dislodged otoliths (tiny calcium crystals) that disrupt normal fluid movement in the semicircular canals, causing Vertigo.
• Central Vestibular Disorders: Lesions or damage to the brainstem or cerebellum, such as from a stroke, multiple sclerosis, or a tumor, can lead to central Vertigo. These conditions affect the central processing of balance information, resulting in Vertigo.
• Compensatory Mechanisms and Adaptation: The brain can adapt to some degree of vestibular dysfunction through vestibular compensation. However, during the adjustment period, individuals may experience Vertigo as their brain relearns how to interpret balance and spatial orientation signals correctly.

Types of Vertigo

Here are some types of Vertigo; variations and overlaps between them can exist. Proper diagnosis by a healthcare expert is essential:

Types	Description	Common Causes
Peripheral	Issues with the vestibular nerve or inner ear cause Vertigo.	Benign Paroxysmal Positional Vertigo (BPPV), Meniere’s disease, vestibular neuritis, labyrinthitis
Central	Problems in the brain, particularly in the brainstem or cerebellum, cause Vertigo.	Stroke, multiple sclerosis, migraines, brain tumors
BPPV – Benign Paroxysmal Positional	Sudden, mild to severe bouts of Vertigo brought on by particular head posture adjustments.	Displacement of otoliths (small calcium particles) in the inner ear
Meniere’s Disease	Severe Vertigo, hearing loss, tinnitus, and an ear-fullness sensation are all symptoms of a chronic inner ear condition.	Abnormal fluid buildup in the inner ear
Vestibular Neuritis	Inflammation of the vestibular nerve leads to sudden, severe Vertigo.	Viral infection
Labyrinthitis	Inflammation of the inner ear labyrinth causes disorientation and loss of hearing.	Viral or bacterial infection
Migrainous	It is associated with migraine headaches.	Migraines
Vestibular Paroxysmia	Brief, repeated episodes of Vertigo caused by neurovascular compression of the vestibular nerve.	Blood vessels compressing the vestibular nerve
Cervicogenic	It resulting from neck pain or dysfunction.	Cervical spine disorders, whiplash
Superior Canal Dehiscence Syndrome (SCDS)	It occurs by loud noises or changes in pressure, and it is caused by thinning or absent bone covering the superior semicircular canal.	Abnormal opening in the bone

Symptoms

The underlying cause of the Vertigo will determine the degree and duration of the symptoms. If you’re experiencing any of these symptoms, it’s essential to consult a healthcare professional. Here are the symptoms:

• Spinning Sensation: The primary symptom is feeling like you or your surroundings are spinning or moving, even when you’re perfectly still.
• Nausea and Vomiting: It often induces nausea and may lead to vomiting, especially if the spinning sensation is severe.
• Balance Problems: Individuals with Vertigo may experience difficulty maintaining balance and coordination, leading to instability and potential falls.
• Nystagmus refers to involuntary eye movements, often characterized by jerking or rapid movements of the eyes. It commonly accompanies Vertigo.
• Headaches: Headaches can range in intensity from minor to severe and sometimes come with accompanying symptoms like light or sound sensitivity in individuals with Vertigo.

Diagnosis

Healthcare experts can make an accurate diagnosis of Vertigo by considering these factors together; here are some:

• Medical History: Usually, a doctor will begin by acquiring a thorough medical history that includes information on the symptoms, duration, triggers, and any prior instances of Vertigo.
• Physical Examination: This may involve assessing balance, coordination, eye movements, and hearing. The Dix-Hallpike maneuver, which involves specific head and body movements to provoke Vertigo, might be performed to diagnose benign paroxysmal positional Vertigo (BPPV).
• Vestibular Function Tests: These tests evaluate the function of the inner ear and vestibular system. Standard tests include the caloric test (which measures responses to warm and cold air or water in the ear canal) and electronystagmography (ENG) or videonystagmography (VNG), which tracks eye movements in response to stimuli.
• Imaging: In some cases, healthcare experts may order tests such as imaging tests, MRIs, or CT scans to rule out structural problems with the inner ear or brain.
• Laboratory Tests: Doctors may perform blood testing to look for underlying diseases, such as infections or metabolic problems, that might cause Vertigo.

Treatment Options

A healthcare professional’s advice is crucial if you want an accurate diagnosis and a customized treatment plan for your unique needs and condition.

• Epley maneuver: When a patient has benign paroxysmal positional Vertigo (BPPV), a medical practitioner will move the patient’s head in a specific order to realign inner ear crystals that may be causing the Vertigo.
• Vestibular Rehabilitation: This physical therapy enhances balance and stability while fortifying the vestibular system. It entails particular movements and exercises intended to retrain the brain to process inner ear signals correctly.
• Medications: Depending on what causes the Vertigo, doctors may recommend drugs to treat the symptoms. For example, they might take antihistamines or antiemetics to lessen vertigo-related nausea and vomiting. Doctors may recommend corticosteroids or antiviral medications if inflammation or an inner ear infection are the underlying causes.
• Repositioning procedures: A local Hornsby physio can reposition the dislodged inner ear crystals to their original location using the Epley maneuver to treat BPPV. Examples include the Semont maneuver and the Brandt-Daroff exercises.
• Surgery: In rare cases of severe Vertigo that doesn’t respond to other treatments, surgeons may consider performing surgical procedures involving repairing or removing inner ear or vestibular nerve structures.
• Lifestyle Modifications: Changing your daily routine or habits may help manage vertigo symptoms. This can include avoiding triggers such as caffeine, alcohol, and tobacco, maintaining hydration, and getting enough sleep. Additionally, using assistive devices such as walking aids or handrails can help prevent falls during episodes of Vertigo.
