Vertigo is a common condition that affects millions of people worldwide. It is characterized by a sensation of spinning or dizziness, often leading to balance issues and difficulty performing everyday activities. In this blog, we'll explore what vertigo is, its causes, symptoms, and available treatment options.
What is Vertigo?
Vertigo is not a disease but rather a symptom of an underlying issue. People with vertigo feel as though they or their surroundings are moving or spinning when in fact, they are stationary. It can be a temporary condition, lasting only a few seconds, or a persistent issue that disrupts a person's life for longer periods.
Types of Vertigo
There are two primary types of vertigo:
Peripheral Vertigo: This is the most common type and occurs due to a problem within the inner ear, particularly the vestibular system that controls balance. Conditions like Benign Paroxysmal Positional Vertigo (BPPV), vestibular neuritis, and Ménière's disease fall under this category.
Central Vertigo: This type occurs due to problems within the brain, particularly the brainstem or cerebellum. It can be caused by migraines, strokes, or tumors.
Causes of Vertigo
There are various causes, depending on whether the vertigo is peripheral or central in nature:
BPPV (Benign Paroxysmal Positional Vertigo): One of the most common causes, BPPV occurs when tiny calcium particles (canaliths) become dislodged and float within the inner ear's semicircular canals, causing dizziness during specific head movements.
Vestibular Neuritis or Labyrinthitis: These are infections, usually viral, that affect the inner ear and cause vertigo. In labyrinthitis, hearing loss may also be present.
Ménière's Disease: This is a chronic condition affecting the inner ear, causing episodes of vertigo, hearing loss, tinnitus (ringing in the ears), and a feeling of fullness in the ear.
Migraines: Some people experience vertigo as part of their migraine episodes, commonly referred to as vestibular migraines.
Head Injuries: Trauma to the head or neck can disrupt the vestibular system and lead to vertigo.
Stroke or Transient Ischemic Attack (TIA): Central vertigo can sometimes be a sign of a stroke or a TIA (mini-stroke) and should be evaluated promptly.
Symptoms of Vertigo
Dizziness or spinning sensation: The most common symptom, where individuals feel like they or their surroundings are moving.
Balance issues: Difficulty maintaining equilibrium, often leading to unsteadiness.
Nausea or vomiting: Feeling sick due to the disorienting nature of vertigo.
Nystagmus: Rapid, involuntary eye movements that may accompany vertigo episodes.
Sweating and anxiety: Vertigo can also trigger stress responses, as the sensation can be quite unsettling.
Diagnosis of Vertigo
To diagnose vertigo, healthcare providers often conduct a thorough medical history and physical examination. Key diagnostic tools include:
Dix-Hallpike maneuver: A common test to diagnose BPPV, where the doctor moves the patient's head in specific directions to trigger symptoms.
Electronystagmography (ENG) or Videonystagmography (VNG): These tests measure abnormal eye movements and can help assess whether the vertigo is due to a peripheral or central cause.
MRI or CT scans: In cases of suspected central vertigo, imaging may be necessary to rule out tumors, strokes, or other brain abnormalities.
Other tests: Video Head Impulse Test (vHIT), Rotary chair test, Sensory Interaction on Balance tests (mCTSIB) and Vestibular Evoked Myogenic Potentials (VEMPs) are some other tests used to explore the causes of vertigo.
Treatment Options for Vertigo
The treatment of vertigo depends on the underlying cause:
Canalith Repositioning Maneuvers: For BPPV, techniques such as the Epley maneuver are highly effective in repositioning the dislodged particles within the inner ear, providing relief.
Medications: For acute vertigo episodes, medications like antihistamines (e.g., meclizine) or anti-nausea drugs can help alleviate symptoms. In some cases, benzodiazepines may be prescribed for anxiety associated with vertigo.
Vestibular Rehabilitation Therapy (VRT): A type of physical therapy, VRT focuses on strengthening the vestibular system through exercises designed to improve balance and reduce dizziness. Vestibular exercises train the brain to maintain balance that ultimately decreases vertigo symptoms, movement provoked dizziness and an overall improvement in activities of daily living. Several randomized control trials have proven the benefits of vestibular rehabilitation exercises in the management of vertigo.
Dietary Changes: In conditions like Ménière's disease, a low-sodium diet may be recommended to reduce fluid retention in the inner ear.
Surgical Options: In severe cases of vertigo caused by Ménière's disease or other structural issues, surgery may be considered as a last resort.
Managing Triggers: For those with vestibular migraines, avoiding known triggers (e.g., certain foods, stress, or lack of sleep) is key to reducing the frequency and severity of vertigo episodes.

Living with Vertigo
Although vertigo can be distressing, many treatment options can help manage the condition effectively. It is essential to consult with a audiologist healthcare provider, especially if the vertigo is sudden, severe, or accompanied by other symptoms like hearing loss or weakness, as these may indicate a more serious issue. With the right diagnosis and management plan, people with vertigo can significantly improve their quality of life.
Conclusion
Vertigo is a condition that affects balance and spatial orientation, leading to dizziness and disorientation. While it can be caused by several factors, from inner ear issues to brain conditions, effective treatments are available. Understanding the symptoms and seeking proper medical care is the first step in managing vertigo and regaining control over daily life.
