Vertigo is not a disease. It is a symptom, specifically a false sensation of spinning or movement that originates from a problem in your balance system. The distinction matters because vertigo always points to an underlying cause, whether that’s something minor like loose crystals in your inner ear or something serious like a stroke affecting the brain. About 7.8% of adults will experience vertigo at some point in their lives, and finding the right treatment depends entirely on identifying what’s behind it.
What Vertigo Actually Is
Your inner ear contains a network of fluid-filled canals that detect the rotation and position of your head. Tiny hair cells inside these canals shift when the fluid moves, sending signals to your brain about which direction you’re turning and how fast. Vertigo happens when something disrupts this system, sending conflicting signals that make your brain think you’re moving when you’re not. The result is that characteristic spinning sensation, often accompanied by nausea, imbalance, and involuntary eye movements called nystagmus.
Because vertigo is a symptom rather than a diagnosis, telling your doctor “I have vertigo” is similar to saying “I have a fever.” The next question is always: what’s causing it?
The Most Common Causes
The conditions behind vertigo fall into two broad categories based on where the problem originates: the inner ear (peripheral) or the brain and brainstem (central). Peripheral causes account for the large majority of cases and are generally less dangerous.
Benign Paroxysmal Positional Vertigo (BPPV)
BPPV is by far the most common cause of vertigo. Inside your inner ear, tiny calcium carbonate crystals help you sense gravity and linear movement. Sometimes these crystals break loose from their normal position and drift into one of the semicircular canals, where they don’t belong. Once there, they shift with head movements, pushing on fluid and hair cells in a way that sends false rotation signals to the brain. This is why BPPV triggers brief but intense spinning when you roll over in bed, tilt your head back, or look up.
The crystals typically detach due to age-related wear, though head injuries and ear infections can also dislodge them. The good news is that BPPV responds remarkably well to a simple repositioning technique called the Epley maneuver, where a clinician guides your head through a specific sequence of positions to move the crystals out of the canal. Studies report that about 72% of patients recover immediately after the maneuver, and 92% are free of vertigo within one week.
Vestibular Neuritis and Labyrinthitis
These two conditions are closely related and usually triggered by a viral infection that inflames structures in the inner ear. Vestibular neuritis affects only the balance nerve, so you get severe vertigo, nausea, and trouble with balance, but your hearing stays intact. Labyrinthitis involves both the balance nerve and the hearing structures (the cochlea), so it adds hearing loss or ringing in the ear on top of the vertigo. The hearing loss from labyrinthitis is typically permanent.
Both conditions cause sudden, intense vertigo that can last more than a day before gradually improving. Recovery takes weeks, sometimes longer, as the brain learns to compensate for the damaged side.
Ménière’s Disease
Ménière’s disease causes recurring episodes of vertigo lasting anywhere from 20 minutes to 12 hours, along with fluctuating hearing loss in one ear, a feeling of fullness or pressure in that ear, and tinnitus. It’s diagnosed when a person has had at least two spontaneous vertigo episodes meeting this pattern, with documented hearing loss on a hearing test. The condition is unpredictable, with episodes that cluster for weeks or months and then disappear for long stretches.
When Vertigo Signals Something Serious
Central causes of vertigo, those originating in the brain or brainstem, are less common but far more urgent. Strokes affecting the cerebellum or brainstem can present as sudden vertigo, and certain brain tumors can produce it as well. Vestibular migraines are a more common central cause, producing vertigo episodes that may or may not come with a headache. Multiple sclerosis has also been linked to vertigo through damage to the nerve pathways involved in balance.
The key difference you might notice between peripheral and central vertigo comes down to the eyes. In peripheral vertigo, involuntary eye movements beat consistently in one direction. In central vertigo, the direction of those eye movements can change depending on where you look, and you may notice that your eyes seem misaligned (one eye sitting higher than the other). Central vertigo also tends to produce less dramatic spinning but worse imbalance, making it hard to walk or stand. If your vertigo comes with double vision, slurred speech, difficulty swallowing, weakness on one side, or severe trouble walking, those are signs of a possible stroke or other brain-related cause that needs emergency evaluation.
Who Gets Vertigo Most Often
Vertigo becomes more common with age. Among adults 18 to 39, vestibular vertigo accounts for about 14% of significant dizziness episodes. That proportion doubles to 28% in the 40 to 59 age group and climbs to 37% in people over 60. Women are affected more often than men, and the risk is independently higher in people with depression, tinnitus, high blood pressure, or high cholesterol, based on a large population survey published in the journal Neurology.
How Vertigo Is Diagnosed
Because vertigo is a symptom with many possible causes, diagnosis focuses on figuring out which structure in the balance system is malfunctioning. A common test is videonystagmography (VNG), where you wear goggles with a built-in camera in a dark room. The camera records your eye movements while you follow lights, change head positions, and have warm and cool air or water placed in each ear. The temperature changes are designed to stimulate each inner ear separately, revealing whether one side is weaker than the other.
Doctors also use bedside tests that can quickly distinguish peripheral from central vertigo. One involves turning your head rapidly while you focus on the examiner’s nose. In peripheral vertigo, your eyes make a visible corrective jump back to the target. In central vertigo, they don’t. Another test checks for vertical misalignment between the eyes by alternately covering each one, a sign that points toward a brainstem problem. Hearing tests, MRI scans, and blood work may follow depending on what the initial examination suggests.
How Vertigo Is Treated
Treatment varies completely depending on the underlying cause, which is exactly why the distinction between symptom and disease matters.
For BPPV, repositioning maneuvers are the primary treatment and work quickly for most people. No medication is needed in most cases. For vestibular neuritis and labyrinthitis, the acute phase may be managed with antihistamines like meclizine (available over the counter in many countries) to suppress the spinning sensation and reduce nausea. These medications work by dampening the conflicting signals from the damaged inner ear. They’re meant for short-term use during the worst of it, not as a long-term solution, because they can actually slow the brain’s natural process of adapting to the injury.
Ménière’s disease is managed with dietary changes (primarily reducing salt intake to limit fluid buildup in the inner ear), medications during acute episodes, and sometimes procedures to reduce pressure in the inner ear if episodes are frequent and disabling.
Vestibular rehabilitation therapy, a specialized form of physical therapy, helps with many types of vertigo. It uses targeted exercises to retrain the brain’s balance processing. For people whose vertigo lingers because the brain hasn’t fully compensated for inner ear damage, this therapy can significantly speed recovery.
Some medications can actually cause vertigo as a side effect, particularly certain anti-seizure drugs and high doses of aspirin-like compounds. If vertigo starts after beginning a new medication, that connection is worth investigating. Anxiety and mood disorders are also independently associated with vertigo and can amplify or perpetuate symptoms even after the original inner ear problem has resolved.
