Introduction
Vertigo is the sensation that you or your surroundings are spinning. It reflects a mismatch in balance signals from the inner ear, eyes, and proprioceptive system, not simply feeling faint.
Common causes include benign paroxysmal positional vertigo (BPPV), vestibular neuritis, Meniere disease, and migraine-associated vertigo. Central causes such as stroke are less common but must be excluded when red flags exist.
Treatment depends on diagnosis: repositioning maneuvers for BPPV, vestibular suppressants short term, rehabilitation exercises, and migraine or Meniere-specific therapies.
This page explains common symptoms, how evaluation usually proceeds, treatment options, and when to seek medical care.
Overview
Peripheral vertigo often has abrupt onset with nausea and nystagmus beating in predictable direction. Central vertigo may accompany neurologic deficits, severe headache, or inability to walk.
Most episodic vertigo is benign, but acute continuous vertigo with stroke risk factors needs urgent evaluation.
- Spinning sensation from balance system disorder
- Distinct from lightheadedness or presyncope
- BPPV is most common peripheral cause
- Vestibular neuritis causes prolonged acute vertigo
- Repositioning maneuvers treat BPPV effectively
- Red flags suggest possible central cause
What happens in the body
Asymmetric input from semicircular canals or otolith organs makes the brain interpret head motion when none exists. Inflammation or debris (otoliths) disrupts normal vestibular firing.
Central lesions affect brainstem or cerebellar integration, sometimes without hearing loss but with other neurologic signs.
- Otoconia dislodged into semicircular canal (BPPV)
- Vestibular nerve inflammation after viral illness
- Endolymphatic hydrops disturbs Meniere ear
- Central mismatch from cerebellar or brainstem lesion
Signs and symptoms
Common symptoms and warning signs may include:
- Spinning sensation lasting seconds to days
- Nausea and vomiting
- Unsteadiness or falling to one side
- Nystagmus on exam
- Hearing loss or tinnitus with Meniere or labyrinthitis
- Triggered by head movement in BPPV
- Headache and light sensitivity if vestibular migraine
- Double vision or weakness suggests central cause
Causes and risk factors
Possible causes and contributing factors include:
- Benign paroxysmal positional vertigo
- Vestibular neuritis or labyrinthitis
- Meniere disease
- Vestibular migraine
- Head trauma
- Medications toxic to inner ear
- Posterior circulation stroke or TIA
- Acoustic neuroma rarely
Diagnosis and evaluation
Evaluation may include:
- History of episode timing and triggers
- Dix-Hallpike test for BPPV
- Head impulse, nystagmus, skew test (HINTS) for acute vestibular syndrome
- Audiometry when hearing involved
- MRI if central stroke or tumor suspected
- Differentiate from orthostatic hypotension and anxiety
Treatment and management
Treatment and management may involve:
- Epley or other canalith repositioning for BPPV
- Short course vestibular suppressants: meclizine, dimenhydrinate
- Steroids early in vestibular neuritis when severe
- Vestibular rehabilitation exercises
- Meniere: low salt, diuretics, hearing strategies
- Migraine preventive therapy for vestibular migraine
- Treat stroke or central cause urgently when identified
- Avoid prolonged suppressant use delaying compensation
Prevention, self-care, and lifestyle
Not every condition is fully preventable, but the steps below may lower risk or recurrence:
- Fall precautions during acute episodes
- Manage cardiovascular risk factors to reduce stroke-related vertigo
- Hydration and gradual movement changes in elderly
Possible complications
Delay, missed care, or unsafe self-medication can raise the chance of complications in some cases:
- Falls and injury
- Chronic imbalance after incomplete compensation
- Hearing loss progression in Meniere
- Missed stroke if peripheral cause assumed incorrectly
- Dehydration from persistent vomiting
When to see a doctor or seek emergency care
Seek prompt medical advice or emergency care if any of the following apply—it is safer not to wait and see:
- Vertigo with weakness, numbness, severe headache, or unable to walk
- New hearing loss in one ear
- Continuous vertigo beyond a few days without improvement
- Head trauma preceding vertigo
Living with the condition
During BPPV flares, sleep with head slightly elevated and move slowly. Vestibular rehab homework retrains balance and reduces chronic dizziness better than long-term sedating medicines.
Frequently asked questions
Is vertigo the same as fear of heights?
No. Acrophobia is anxiety with heights. Vertigo is a spinning sensation usually from inner ear or brain balance pathways.
Will BPPV come back?
Recurrence is common. Repositioning maneuvers can be repeated at home or in clinic when symptoms return.
