Most vertigo has a specific, identifiable cause, and once you know the cause, the right treatment can resolve symptoms quickly. The single most common form of vertigo seen in primary care is benign paroxysmal positional vertigo (BPPV), which can often be eliminated in a single clinic visit using a simple head-repositioning maneuver. But vertigo that lingers or returns usually signals a different underlying condition, and the fix changes accordingly.
Why the Cause Matters More Than the Symptom
Vertigo is a symptom, not a disease. A systematic review of vertigo cases in primary care found that the conditions most likely to be responsible are BPPV, vestibular neuritis, and Ménière’s disease, though vascular events and neurological causes like multiple sclerosis also need to be considered.1PubMed Central. A systematic review of vertigo in primary care Another large review of dizziness in general practice found that the proportion attributed to different causes varies enormously across studies, with peripheral vestibular problems accounting for anywhere from about 5% to 42% of cases and cardiovascular causes showing up in roughly 4% to 57%.2PubMed Central. Prevalence, aetiologies and prognosis of the symptom dizziness in primary care – a systematic review Those wide ranges reflect how differently doctors in different settings define and categorize dizziness. The practical takeaway is that no single cure works for all vertigo, because the word covers very different problems.
That said, if you are reading this because the room spins briefly when you roll over in bed or tip your head back, you probably have BPPV, and the news is genuinely good.
The Epley Maneuver for BPPV
BPPV happens when tiny calcium carbonate crystals (sometimes called “ear rocks”) drift into one of the semicircular canals of your inner ear. Every time you move your head into a certain position, the loose crystals slosh around and send a false motion signal to your brain. The fix is a guided sequence of head and body positions that uses gravity to float the crystals back where they belong. The most widely studied version is the Epley maneuver.
In one prospective trial, about 72% of patients treated with the Epley maneuver recovered from vertigo immediately, and 92% had recovered by the one-week follow-up. Patients who received the maneuver were roughly six times more likely to recover than controls who did not.3PubMed Central. Efficacy of Epley’s Maneuver in Treating BPPV Patients: A Prospective Observational Study Another study found that about two-thirds of patients were successfully repositioned on the first attempt with the traditional Epley, and most of the rest resolved on a second or third try.4PubMed Central.

The maneuver itself takes a few minutes. A clinician turns your head at specific angles while you move from sitting to lying back, holds each position for about 30 seconds, then rolls you onto your side and sits you upright. If done correctly and the crystals cooperate, the spinning sensation disappears on the spot. It sounds almost too simple, and for decades the medical community treated the idea with skepticism. John Epley first proposed his canalith repositioning procedure in 1980 and published a study showing a 100% success rate in 30 patients, but the maneuver was not formally recognized as a recommended treatment in a major journal until 1999.5Neurology. John McNaughton Epley: His Life and Theory That Challenged Convention in the Study of Benign Paroxysmal Positional Vertigo
Getting diagnosed properly matters, because the maneuver only works if BPPV is the actual problem. The standard diagnostic test, the Dix-Hallpike maneuver, has an estimated sensitivity of about 79% and specificity of about 75%.6PubMed. Establishing a diagnosis of benign paroxysmal positional vertigo through the dix-hallpike and side-lying maneuvers: a critically appraised topic That means it catches most BPPV cases but misses some. If the first diagnostic attempt is negative and your doctor still suspects BPPV, repeating the maneuver can pick up additional cases: one study found 28 more patients diagnosed out of 207 after repeated testing beyond the first attempt.7PubMed Central. Diagnostic value of repeated Dix-Hallpike and roll maneuvers in benign paroxysmal positional vertigo
Doing Repositioning Maneuvers at Home
If you have confirmed BPPV and it recurs, you can learn to do repositioning maneuvers yourself. The self-administered Epley follows the same sequence of positions used in the clinic, and a simpler alternative called the half somersault (or Foster maneuver) involves kneeling on the floor, tucking your head down, rotating it toward the affected ear, and then raising your head while staying in a kneeling position.
A comparison of the two home exercises found that the Epley was more effective at eliminating the spinning right away, with about 61% of patients resolving after one self-administered maneuver compared to 35% for the half somersault.8PubMed Central. The Efficacy of the Half Somersault Maneuver in Comparison to the Epley Maneuver in Patients with Benign Paroxysmal Positional Vertigo However, a separate trial found that the half somersault caused less dizziness during the exercise itself and had fewer treatment failures over a six-month follow-up, suggesting it may be the better option for long-term self-management even though it works more slowly.9Audiology and Neurotology Extra. A Comparison of Two Home Exercises for Benign Positional Vertigo: Half Somersault versus Epley Maneuver If the Epley makes you too nauseated to complete it at home, the half somersault is a reasonable fallback.
What to Do After a Repositioning Maneuver
Patients often receive a list of restrictions after their Epley: sleep sitting up, don’t turn your head, avoid bending over. The evidence behind these instructions is thinner than you might expect. One study found that posture restrictions after the maneuver did not change outcomes, with the Epley working in about 70% of cases regardless of what patients did afterward.10PubMed Central. Posture restrictions do not interfere in the results of canalith repositioning maneuver
The one post-maneuver behavior that did seem to matter was sleep position. A separate study found that patients who slept on their affected side after repositioning had a higher recurrence rate, while sleeping propped up at 30 degrees did not lower recurrence compared to sleeping in a random position. The practical advice from that study is simple: avoid sleeping on the ear that was affected, but don’t bother with an elaborate propped-up sleeping arrangement.11PubMed Central. Impact of Postmaneuver Sleep Position on Recurrence of Benign Paroxysmal Positional Vertigo
Vitamin D and BPPV Recurrence
BPPV comes back. Even after a successful repositioning, those crystals can break loose again. One of the more interesting findings in recent years is that vitamin D supplementation may reduce the recurrence rate. A randomized trial found that patients who took vitamin D (when their blood levels were low to begin with) had a recurrence rate roughly 24% lower than those who were simply observed. The proportion who experienced any recurrence dropped from about 47% in the observation group to about 38% in the vitamin D group.12PubMed. Prevention of benign paroxysmal positional vertigo with vitamin D supplementation: A randomized trial The thinking is that low vitamin D weakens the structures that hold calcium carbonate crystals in place, making them more likely to detach. If your BPPV keeps returning, having your vitamin D level checked and supplementing if it is low is one of the few preventive measures with real trial data behind it.
Vestibular Neuritis and Steroids
If vertigo arrives suddenly, is constant rather than triggered by head position, and lasts for days, the likely culprit is vestibular neuritis, an inflammation of the nerve connecting your inner ear to your brain. This is the second most common cause of vertigo, and unlike BPPV, there is no quick mechanical fix. The acute phase is miserable: severe spinning, nausea, and difficulty walking, often lasting several days before slowly improving.
A landmark trial published in the New England Journal of Medicine found that methylprednisolone (a corticosteroid) significantly improved recovery of vestibular function at 12 months compared to placebo, with an average improvement of about 62 percentage points versus 40 for placebo. The antiviral drug valacyclovir, on the other hand, showed no benefit, and adding it to steroids did not improve on steroids alone.13PubMed. Methylprednisolone, valacyclovir, or the combination for vestibular neuritis A meta-analysis confirmed that steroids offer a benefit, though the authors cautioned that the quality of the existing studies was generally low and confidence intervals were wide.14PubMed. Corticosteroids in patients with vestibular neuritis: An updated meta-analysis
Timing appears to matter. A study of patients treated with steroids found that all nine patients treated within 24 hours of symptom onset had normal vestibular function at three months, compared to just 58% of those treated between 25 and 72 hours.15PubMed Central. Steroids for Acute Vestibular Neuronitis—the Earlier the Treatment, the Better the Outcome? That was a small study, but it reinforces the general principle: if you wake up with sudden, severe, constant vertigo, getting to a doctor the same day is worth the effort.
Vestibular Migraine
Vestibular migraine causes episodes of vertigo that can last minutes to days, often accompanied by headache, light or sound sensitivity, or visual aura, though sometimes the dizziness occurs without any headache at all. That last point is what makes it tricky to diagnose: people don’t think “migraine” when they have no head pain.
Treatment borrows from the standard migraine toolkit. During an acute episode, usual migraine abortive medications may help. For people with frequent attacks, preventive medications including propranolol, topiramate, valproic acid, lamotrigine, and flunarizine can reduce the frequency and severity of episodes.16PubMed Central. The Treatment of Vestibular Migraine: A Narrative Review Lifestyle adjustments that help migraineurs in general also tend to help here: regular sleep, consistent meals, managing stress, and identifying personal triggers like certain foods or alcohol.
Ménière’s Disease
Ménière’s disease produces episodes of vertigo lasting 20 minutes to several hours, along with fluctuating hearing loss, tinnitus, and a sense of fullness in the affected ear. It is thought to involve an excess of fluid in the inner ear. First-line treatment typically involves dietary modifications: reducing salt, cutting alcohol, and limiting caffeine. While some studies have shown a positive effect of these dietary changes, including a reduction in recurrence of attacks, there is no firm consensus on how useful they truly are.17PubMed Central. Dietary Restriction for The Treatment of Meniere’s Disease Diuretics are often prescribed alongside the diet changes, and for severe cases, steroid injections into the middle ear or surgical options may be considered. Ménière’s is one of the more frustrating forms of vertigo to manage because responses to treatment vary widely and the disease can be unpredictable.
The Anxiety-Dizziness Feedback Loop
After an episode of vertigo from any cause, some people develop persistent dizziness that outlasts the original problem. The room may not spin anymore, but there is a constant unsteadiness, a feeling of rocking or swaying, and a dread of the environments that seem to trigger it: busy supermarkets, open spaces, scrolling screens. This pattern is now formally recognized as persistent postural-perceptual dizziness (PPPD), and it appears to involve a feedback loop between the vestibular system, anxiety, and the brain’s posture-control systems.
The treatment that has the best evidence for PPPD is a combination of vestibular rehabilitation therapy (exercises that retrain balance) and cognitive behavioral therapy (CBT). A systematic review of randomized trials found that combining vestibular rehabilitation with CBT or other psychologically informed approaches yielded larger and more consistent reductions in dizziness-related disability and maladaptive beliefs than vestibular rehab alone.18PubMed Central. Anxiety-Related Functional Dizziness: A Systematic Review of the Recent Evidence on Vestibular, Cognitive Behavioral, and Integrative Therapies A meta-analysis specifically in PPPD patients confirmed that adding CBT to conventional therapies improved dizziness handicap scores significantly, whether the conventional therapy was vestibular rehab alone, an SSRI antidepressant, or both combined.19Brazilian Journal of Otorhinolaryngology. Additional cognitive behavior therapy for persistent postural-perceptual dizziness: a meta-analysis
Antidepressant medication, particularly SSRIs, may also help, though the evidence for medication alone is considered weaker.20PubMed. Treatment of Persistent Postural-Perceptual Dizziness (PPPD) and Related Disorders If your vertigo “cured” months ago by objective measures but you still feel unsteady and anxious about it, PPPD is worth discussing with your doctor. People often feel dismissed when told their dizziness is related to anxiety, but it is a real neurological condition with measurable brain changes, and the combination treatment genuinely works.
Cervicogenic Dizziness
Sometimes dizziness originates not in the ear but in the neck. Cervicogenic dizziness is linked to dysfunction in the joints, muscles, or proprioceptive system of the upper cervical spine. It tends to show up alongside neck pain and stiffness, and it is a diagnosis of exclusion: you get it after inner-ear and brain causes have been ruled out.
When diagnosed correctly, cervicogenic dizziness responds well to manual therapy and vestibular rehabilitation.21PubMed. Cervicogenic dizziness: a review of diagnosis and treatment A randomized trial found that two forms of manual therapy, sustained natural apophyseal glides and passive joint mobilizations, both produced less dizziness, lower handicap scores, and improved neck range of motion compared to placebo at 12 months, with no adverse effects.22PubMed. Manual therapy for cervicogenic dizziness: Long-term outcomes of a randomised trial Adding targeted self-exercises that include strength training, mobilization, and eye-movement coordination can further help relieve dizziness symptoms by improving balance and motor control.23PubMed Central. The efficacy of self-exercise in a patient with cervicogenic dizziness: A randomized controlled trial
If you spend long hours at a desk, have chronic neck tension, and notice your dizziness tracks with neck stiffness or turning your head rather than with rolling over in bed, this is a possibility worth exploring with a physiotherapist.
Medications That Can Cause Vertigo
A comprehensive review identified evidence of vestibular toxicity in 100 medications, with 23 of those having the strongest grade of evidence.24PubMed. Drug-Induced Ototoxicity: A Comprehensive Review and Reference Guide The usual suspects include certain antibiotics (particularly aminoglycosides), some chemotherapy drugs, loop diuretics at high doses, and certain anti-seizure medications. But medications causing dizziness as a side effect are even more common: 142 drugs in the same review had evidence for causing dizziness of any kind. Blood pressure medications, antidepressants, and anti-anxiety drugs are common culprits in everyday practice.
If your dizziness began around the time you started a new medication or had a dose change, tell your prescriber. Drug-induced dizziness is one of the most fixable causes, because often a dose reduction or switch to a different drug in the same class resolves the problem entirely.
Virtual Reality Vestibular Rehabilitation
For chronic vestibular problems that require extended rehabilitation, virtual reality (VR) is emerging as a useful tool. A meta-analysis found that VR-based rehabilitation significantly reduced dizziness handicap scores in patients with peripheral vestibular disorders compared to conventional therapy or no treatment, and augmented reality approaches also showed significant benefit.25Scientific Reports. Virtual and augmented reality in the vestibular rehabilitation of peripheral vestibular disorders: systematic review and meta-analysis A second meta-analysis confirmed improvements in dizziness handicap, symptom severity, and posturography measures.26PubMed Central. Effectiveness of virtual reality-based programs as vestibular rehabilitative therapy in peripheral vestibular dysfunction: a meta-analysis Patients in one small trial also reported higher subjective satisfaction with VR-based rehab compared to conventional exercises.27PubMed Central. Virtual Reality Vestibular Rehabilitation in 20 Patients with Vertigo Due to Peripheral Vestibular Dysfunction
An important caveat from the first meta-analysis: the benefit was clear for in-clinic VR sessions, but home-based VR programs did not show a significant advantage over control treatments. So this is not yet a matter of buying a VR headset and running an app on your own. The technology works best when guided by a therapist who can adjust the difficulty and monitor your responses.
When Vertigo Is an Emergency
Most vertigo is benign, but sudden, continuous vertigo can occasionally be a sign of stroke in the back of the brain. Emergency physicians and neurologists use a bedside exam called HINTS (Head Impulse, Nystagmus, Test of Skew) to distinguish vestibular neuritis from a posterior circulation stroke. When performed by neurologists, the HINTS exam had a sensitivity of about 97% and specificity of about 95% for detecting stroke.28PubMed. Can Emergency Physicians Accurately Rule Out a Central Cause of Vertigo Using the HINTS Examination? A Systematic Review and Meta-analysis When emergency physicians were included, accuracy dropped substantially, which reflects how much the exam depends on the examiner’s skill.
A separate systematic review reported pooled sensitivity of about 96% and specificity of about 71% for detecting stroke using HINTS in patients presenting with acute vestibular syndrome.29PubMed Central. Posterior circulation stroke diagnosis using HINTS in patients presenting with acute vestibular syndrome: A systematic review You do not need to memorize these numbers. The practical rule is this: if vertigo appears suddenly, is constant (not triggered by position changes), and comes with any neurological symptoms, including double vision, slurred speech, trouble swallowing, weakness on one side, severe headache, or an inability to walk, go to an emergency room. Even without those additional symptoms, sudden severe vertigo that does not let up within hours warrants urgent evaluation, because posterior circulation strokes can initially look like vestibular neuritis and the two require very different treatment timelines.
