What Is Vertigo?
Vertigo is a false sensation of movement, typically described as spinning, tilting, swaying, or a feeling that the surroundings are moving. It is not a disease itself but a symptom of an underlying condition, most commonly involving the inner ear or the brain.
Vertigo differs from general dizziness in that it specifically involves a sense of rotational motion. Inner ear (vestibular system) disorders are the most frequent cause.
Symptoms of Vertigo
The primary symptom is a spinning or off-balance sensation. Depending on the underlying cause, vertigo may also be associated with:
- Nausea and vomiting
- Difficulty focusing vision
- Hearing loss in one or both ears
- Ear fullness or blockage sensation
- Ringing in the ears (tinnitus)
- Loss of balance or unsteadiness
- Headache
- Motion sensitivity
Symptoms Suggesting Central (Brain-Related) Vertigo
When vertigo originates from the brain, additional neurological symptoms may occur:
- Double vision
- Difficulty swallowing
- Slurred speech
- Facial weakness
- Limb weakness
- Abnormal eye movements
Central vertigo requires urgent neurological evaluation.
Causes of Vertigo
Vertigo is broadly classified into:
- Peripheral Vertigo: Caused by disorders of the inner ear
- Central Vertigo: Caused by conditions affecting the brain
Common Causes of Peripheral Vertigo
- Benign paroxysmal positional vertigo (BPPV) Occurs when tiny calcium crystals (otoconia) become displaced within the inner ear. Specific head movements trigger brief spinning episodes.
- Labyrinthitis Inflammation of the inner ear, often following a viral infection.
- Vestibular neuritis Inflammation of the vestibular nerve, disrupting balance signals to the brain.
- Ménière’s disease Characterized by vertigo episodes, tinnitus, ear pressure, and fluctuating hearing loss.
- Bone growth in the middle ear
Causes of Central Vertigo
- Migraine
- Multiple sclerosis
- Acoustic neuroma
- Cerebellar brain tumors
- Stroke
- Certain medications (e.g., antibiotics, anti-inflammatory drugs, cardiovascular medications)
Other contributing factors may include hyperventilation or systemic illness.
Diagnosis of Vertigo
Accurate diagnosis is essential to distinguish between peripheral and central causes. Evaluation may include:
- Detailed medical history
- Neurological examination
- Balance and eye movement testing
- Hearing assessment
- Imaging studies (MRI or CT scan) if central causes are suspected
Identifying the precise cause determines the most effective treatment plan.
Treatment of Vertigo
Treatment depends on the underlying diagnosis. In some cases, vertigo resolves spontaneously as the brain adapts to vestibular changes.
Common Treatment Approaches
1. Vestibular Rehabilitation Therapy (VRT)
A specialized exercise program designed to strengthen the vestibular system and improve balance, coordination, and visual stability.
2. Medications
- Antiemetics for nausea
- Antihistamines for motion-related symptoms
- Steroids or antibiotics if infection or inflammation is present
3. Repositioning Maneuvers (for BPPV)
Specific head and body movements to relocate displaced crystals within the inner ear.
4. Surgical Intervention
Reserved for selected cases where conservative treatments fail.
When Should You See a Neurologist?
Seek medical evaluation if:
- Vertigo is recurrent or severe
- Symptoms interfere with daily activities
- Neurological symptoms (speech difficulty, weakness, double vision) occur
- There is sudden hearing loss or persistent imbalance
Prompt evaluation ensures accurate diagnosis and appropriate management.
Specialized Vertigo Care
Comprehensive vertigo management requires:
- Advanced diagnostic assessment
- Differentiation between peripheral and central causes
- Individualized treatment planning
- Multidisciplinary care including neurology and vestibular rehabilitation
With precise diagnosis and targeted therapy, most patients experience significant relief and restoration of balance and function.
