BPPV: The Most Common Cause of Vertigo and the Maneuver That Fixes It

It usually starts in bed. You roll toward the alarm clock and the ceiling swings sideways like a boat coming off its mooring. Twenty seconds later it stops, and you lie very still, wondering whether something has gone wrong in your brain. For most people who describe that scene, the answer is BPPV, a mechanical problem in the inner ear that is frightening in the moment and, in most cases, fixable in a clinic chair.

BPPV is having a moment online. As of May 2026, short videos of physical therapists guiding patients through the Epley maneuver have racked up hundreds of millions of views, and the comment sections are full of people asking whether they can do it themselves on the sofa. Some of the advice circulating is excellent. Some of it skips the step that matters most: knowing which ear, and which canal, is causing the trouble.

This is the long version, built from the clinical guideline and the trials behind it rather than from a 40-second clip.

What is BPPV, in plain words?

Benign paroxysmal positional vertigo is a name that explains itself once you unpack it. Benign means it is not dangerous in itself. Paroxysmal means it comes in sudden, short bursts. Positional means a change in head position sets it off. Vertigo is the sensation that you or the room is moving when neither is.

The machinery involved sits deep in the inner ear. Each ear contains three semicircular canals, fluid-filled loops that detect rotation of the head, and two small organs, the utricle and saccule, that detect gravity and straight-line movement. The gravity sensors work because they hold a bed of tiny calcium carbonate crystals called otoconia, which press on sensory hair cells when you tilt or accelerate.

BPPV happens when some of those crystals come loose and drift into a semicircular canal, most often the posterior canal, which sits lowest when you lie down. That single canal accounts for roughly 85 to 95 percent of cases, according to the clinical practice guideline from the American Academy of Otolaryngology–Head and Neck Surgery. The horizontal canal is a distant second. The anterior canal is rare enough that many clinicians question whether it occurs at all.

Once the crystals are in the wrong place, physics takes over. Tilt your head and the heavy debris slides through the canal fluid, dragging on the sensor at the canal’s base. Your brain receives a strong rotation signal from one ear and nothing matching from the other. The result is the spinning sensation, plus a characteristic flick of the eyes called nystagmus that clinicians use for diagnosis. When the crystals settle, the signal stops. That is why an attack of BPPV rarely lasts longer than a minute.

What does a BPPV attack actually feel like?

People describe it in remarkably similar ways: the room tips, spins or slides, most often when they lie down, roll over in bed, sit up in the morning, tilt the head back to look at a high shelf, or bend forward to tie a shoe. The spinning builds over a second or two, peaks, and fades within 30 to 60 seconds. Between episodes many people feel steady, though a low-grade wooziness or a sense of being slightly off balance can linger for hours.

Nausea is common. Vomiting is less so, but it happens, particularly with the horizontal-canal variety, which tends to produce stronger spinning. What BPPV does not do is cause hearing loss, ringing in the ears, a feeling of fullness in the ear, or a constant spinning that continues while you sit still. Those features point toward other diagnoses, such as vestibular neuritis or Ménière’s disease, or in rarer cases toward a problem in the brain rather than the ear.

Timing is the clue most worth remembering. Mayo Clinic notes that BPPV episodes are brief and almost always tied to a specific head movement. If your dizziness has lasted continuously for an hour, or if it appears without any change in position, the mechanical crystal explanation does not fit well, and a clinician will look elsewhere.

Fear amplifies the experience. Many people with a first attack are convinced they are having a stroke, and that is a reasonable worry to raise with a doctor. The reassurance, once BPPV is confirmed, is often as therapeutic as the treatment itself. Knowing that the sensation is a loose crystal rather than a failing brain changes how the next episode feels.

What triggers BPPV attacks?

Two different questions hide inside this one. The first is what dislodges the crystals in the first place. The second is what sets off an individual spinning episode once the crystals are loose.

The moment-to-moment triggers are positional and predictable. Lying down flat, rolling from one side to the other in bed, sitting up quickly, tipping the head back at the dentist or hairdresser, and looking down to pick something off the floor are the classic culprits. Each one moves the affected canal through the vertical plane, and gravity does the rest. Standing still and turning your head from side to side, by contrast, rarely provokes posterior-canal BPPV, because that movement does not change the canal’s relationship to gravity.

Why the crystals come loose is murkier. In roughly half of cases, no cause is ever identified, and the guideline calls these idiopathic. When a cause is found, the leading one in people under 50 is a knock to the head, sometimes surprisingly mild. Other associations include a preceding inner-ear infection or inflammation, prolonged bed rest or time in a dental or surgical chair with the head tipped back, migraine, and simply getting older, since the crystal bed appears to become more fragile with age.

Low vitamin D has drawn attention because observational studies have linked deficiency to more frequent recurrences, and one randomized trial suggested that correcting low levels reduced repeat episodes. That is intriguing but rests on limited evidence, and whether to test or treat is a conversation for your own clinician, not a reason to start supplements on your own.

One myth worth retiring here: BPPV is not caused by stress, screen time or a particular diet. Stress can make you notice dizziness more, but it does not shake crystals loose.

Who gets BPPV, and how common is it?

Common enough that most primary care clinicians see it monthly. Among people who go to a doctor because of vertigo, BPPV accounts for somewhere between 17 and 42 percent of diagnoses, depending on the setting and the study. Lifetime prevalence is estimated at about 2.4 percent, meaning roughly one person in 40 will experience it at some point.

Age is the strongest risk factor. Cases climb sharply after 50 and peak between 50 and 70. In people over 65 who report dizziness, BPPV is frequently the explanation, and it is also frequently missed, because older adults may describe unsteadiness rather than spinning and may not connect symptoms to position. Women are affected roughly twice as often as men, a pattern that holds across most population studies, though the reason is not settled.

Head injury is the second major category. Sports concussions, falls, car accidents and even vigorous headbanging at a concert have been documented as preceding events. Post-traumatic BPPV is more likely to involve both ears and more likely to recur, which makes it somewhat harder to treat.

Certain other conditions travel with it. People who have had vestibular neuritis, an inflammation of the balance nerve, develop BPPV at higher rates, probably because the inflammation damages the crystal bed. Ménière’s disease, migraine and osteoporosis each show associations in observational data. The osteoporosis link is biologically plausible, since otoconia are made of calcium carbonate, but the evidence is correlational and does not prove that treating bone density prevents vertigo.

What all these groups share is a crystal bed that is either damaged or aging. Once that has happened, the risk of repeat episodes rises, which matters for the conversation later about whether BPPV goes away for good.

How is BPPV diagnosed, and do you need a scan?

The diagnosis is made with hands and eyes, not machines. The core test is the Dix-Hallpike maneuver: you sit on an examination table, the clinician turns your head 45 degrees toward one side, then lowers you quickly onto your back with your head hanging slightly over the edge. If crystals are loose in the posterior canal of the ear that is now lower, you will feel the spinning within a few seconds and the clinician will see a specific rotating, upbeating nystagmus, a rhythmic flicking of the eyes that builds, peaks and fades in under a minute.

That pattern is diagnostic on its own. The guideline states that clinicians should diagnose posterior-canal BPPV when the Dix-Hallpike test provokes both vertigo and the characteristic nystagmus. For horizontal-canal BPPV, a second test called the supine roll test is used, in which you lie flat and the clinician turns your head to each side.

Here is where evidence-based practice diverges from anxious instinct. The guideline recommends against routine brain imaging and against routine hearing or balance laboratory tests when the history and the positional test are classic. An MRI cannot see otoconia, and ordering one for straightforward BPPV adds delay and cost without changing management. Scans are reserved for cases with atypical features: nystagmus that does not match any canal pattern, neurological symptoms, a maneuver that fails repeatedly, or a history that does not fit.

One practical note from Cleveland Clinic: the test itself reproduces the vertigo, briefly and deliberately. That is uncomfortable but useful. It tells the clinician which ear is affected and which canal, and it means the treatment that follows can be aimed at the right target rather than performed by guesswork.

The Epley maneuver: how canalith repositioning works

The Epley maneuver is the treatment the viral videos are showing, and it deserves its fame. Its formal name is canalith repositioning: a canalith is simply a crystal that has wandered into a canal, and repositioning means using gravity to walk it back out.

The logic is elegant. The posterior canal is a loop with an opening at each end into the utricle, where the crystals belong. If you move the head through a specific sequence of positions, holding each one until the crystals have slid as far as they can, you can roll the debris around the loop and drop it back into the utricle, where it no longer disturbs the rotation sensor and is eventually reabsorbed or stops mattering.

In practice the sequence has four positions, each held for about 30 seconds to a minute or until the spinning stops. It begins in the same head-hanging position as the Dix-Hallpike test on the affected side, then rotates the head toward the opposite side, then rolls the body so the face points toward the floor, and finally brings the person up to sitting. The whole thing takes a few minutes. Many people feel a brief surge of vertigo during the middle positions, which is the debris moving, and then notice that the provoking position no longer produces spinning.

A related technique, the Semont maneuver, uses a rapid swing from lying on one side to lying on the other. Trials suggest it works about as well as the Epley for posterior-canal cases, and some clinicians prefer it for people with neck or back limitations. Horizontal-canal BPPV uses different maneuvers entirely, most commonly a sequence of 90-degree rolls, because the canal sits in a different plane.

The essential point is that each maneuver is canal-specific and side-specific. Done for the wrong ear, the Epley may do nothing or may briefly worsen symptoms.

How do you get rid of BPPV fast, and can you do the Epley maneuver at home?

The fastest reliable route is a clinician-performed repositioning maneuver after a positional test has identified the affected ear and canal. Studies pooled in the Cochrane review found that roughly 80 percent of people with posterior-canal BPPV were symptom-free after one or two treatments, compared with a much smaller share who improved on a sham procedure over the same period. For a condition that would otherwise take weeks to settle on its own, that is about as fast as medicine gets.

Home versions exist, and the guideline acknowledges them as an option. Several trials have compared a self-administered Epley with a clinician-performed one, and the home version works for many people, though somewhat less consistently, chiefly because people misidentify the side or do not hold positions long enough. NHS guidance describes the maneuver as something a doctor or physiotherapist can perform and, in some cases, teach you to repeat.

That word, teach, is the safeguard the viral clips leave out. The sensible sequence is this: get the diagnosis confirmed, have a clinician perform the maneuver and identify the side, then ask whether repeating it at home is appropriate for you and how. Some clinicians will hand you a printed sequence; others will want to see you again first. Either approach is reasonable. What is not reasonable is diagnosing yourself from a comment thread and cranking your neck through a sequence designed for the other ear.

A caution the guideline is explicit about: people with severe neck disease, unstable spine, recent neck surgery, a detached retina, or severe vascular disease should not perform or receive these maneuvers without individual medical assessment. If you have any of those, the video is not for you until a clinician says otherwise.

What changed recently in how BPPV is treated

The honest answer is that the science has been stable for a decade, and what has changed is who is paying attention to it.

The last major turning point was the updated clinical practice guideline published in March 2017 in Otolaryngology–Head and Neck Surgery. It made canalith repositioning the recommended first-line treatment for posterior-canal BPPV, and it made two negative recommendations that reshaped practice: clinicians should not routinely prescribe vestibular suppressant medications, and they should not routinely order imaging or vestibular laboratory testing for classic presentations. It also explicitly listed observation with follow-up as an acceptable alternative for people who prefer to wait.

That guideline built on the Cochrane systematic review updated in December 2014, which pooled randomized trials of the Epley maneuver against sham treatment and found a large, statistically robust advantage for the real maneuver in resolving both symptoms and the diagnostic nystagmus.

Since then, the developments have been incremental. Trials have refined how to treat horizontal-canal BPPV, where the best maneuver was less settled. Home-treatment studies have accumulated. Interest in vitamin D as a recurrence-prevention strategy grew after a randomized trial published in 2020 reported fewer repeat episodes in people whose low levels were corrected, though the finding awaits replication. Consumer health pages from Mayo Clinic, Cleveland Clinic and MedlinePlus, all revised within the past few years, now describe the maneuvers as the standard of care rather than as one option among many.

The 2026 surge in searches is a social-media phenomenon rather than a scientific one: the guideline’s central message, that a hands-on maneuver beats a pill, has finally reached the general public through video. That is good news for the many people whose BPPV was once managed with motion-sickness tablets and patience. It also means the guideline’s cautions deserve equal airtime.

What the evidence actually says, graded honestly

Not every statement in this article stands on the same footing. Here is how the main ones rank.

Strongest evidence: randomized controlled trials pooled in a systematic review. The Epley maneuver relieves posterior-canal BPPV. The 2014 Cochrane review combined trials against sham maneuvers and found clear superiority for both symptom resolution and conversion of the positional test from positive to negative. The trials were modest in size and follow-up was short, so the review graded the certainty as moderate rather than high, but no later trial has contradicted the direction of the result. The Semont maneuver has comparable trial support for the posterior canal.

Moderate evidence: smaller randomized trials. Self-administered maneuvers work, though somewhat less reliably than clinician-performed ones. Specific roll maneuvers help horizontal-canal BPPV. Vitamin D repletion in people with deficiency may reduce recurrence; this rests on a single well-designed trial and observational studies, which is why the guideline discusses it without making a firm recommendation.

Weak or absent evidence. Vestibular suppressant medications such as meclizine relieve nausea but have not been shown in trials to shorten BPPV or reduce attacks, and the guideline recommends against routine use. Brandt-Daroff habituation exercises, a set of repeated side-to-side lying movements once widely prescribed, perform worse than repositioning in head-to-head trials. Post-maneuver restrictions such as sleeping upright or wearing a soft collar for 48 hours, once standard, were tested and found not to improve outcomes; the guideline advises against recommending them.

Expert opinion. Statements about which patients are unsuitable for maneuvers, when to image, and how to handle repeated failures come from clinical consensus rather than trials, because those situations are hard to study. That does not make the advice wrong, but it means reasonable clinicians may differ.

BPPV treatment options compared

The table below summarizes the main approaches a clinician might discuss, what they aim to do, and how well the evidence supports each. It is a map for a conversation, not a menu to choose from alone.

Approach	What it does	Evidence strength	Notes
Epley maneuver (canalith repositioning)	Rolls crystals out of the posterior canal using gravity	Strong: multiple randomized trials, systematic review	Guideline first-line; about 80 percent improve within one to two sessions
Semont maneuver	Rapid side-to-side swing to dislodge crystals	Strong for posterior canal	Comparable to Epley; useful when neck extension is limited
Roll maneuvers	Sequential 90-degree rolls for the horizontal canal	Moderate: smaller trials	Canal-specific; not interchangeable with Epley
Home-taught maneuver	Patient repeats the sequence after clinician instruction	Moderate	Works for many; side misidentification is the main failure
Watchful waiting	Allows crystals to settle or dissolve on their own	Moderate: natural-history data	Guideline-endorsed option; typical resolution in weeks to months
Brandt-Daroff exercises	Repeated positional movements to habituate	Weak; inferior to repositioning in trials	Sometimes used when maneuvers cannot be performed
Vestibular suppressant medicines	Dampen nausea and spinning sensation	Weak for BPPV itself	Guideline recommends against routine use; may aid tolerance of maneuver
Surgery (canal plugging)	Blocks the affected canal	Weak: case series only	Reserved for rare, persistent, disabling cases

Two patterns stand out. The mechanical fixes, which move the crystals, have the best evidence. The chemical fixes, which quiet the symptoms, have the least. That asymmetry is the whole story of modern BPPV care.

What medications are used to treat BPPV?

Fewer than most people expect, and for a specific reason: no medicine can move a crystal.

The drugs historically prescribed for BPPV are vestibular suppressants, a group that damps the brain’s response to conflicting balance signals. They include antihistamines such as meclizine and dimenhydrinate, and benzodiazepines such as diazepam. These can take the edge off nausea and the sensation of spinning, which is why they were used for decades and why some clinicians still reach for them.

The 2017 guideline reviewed the trial evidence and recommended against routinely prescribing them for BPPV. The reasoning is threefold. They do not shorten the course of the condition or reduce the number of attacks, because the mechanical problem remains. They cause drowsiness, which in older adults raises fall risk in a condition that already makes people unsteady. And they can blunt the brain’s natural compensation for balance disturbance, potentially prolonging the lingering unsteadiness between episodes.

There are narrow situations in which a clinician may still use one. Someone whose vomiting is severe enough to prevent a repositioning maneuver may be given a short course to allow the treatment to proceed. Someone with horizontal-canal BPPV that resists maneuvers may be offered symptom relief while the canal settles. These are individual judgments made by the treating clinician, weighing the person’s age, other medications and fall risk.

What about the vitamin D question raised earlier? Vitamin D is not a treatment for an active attack. The interest is in prevention of recurrence in people with documented low levels, and it rests on limited evidence. Whether to check a level and act on it is a decision for your own doctor.

If you already take a medication for dizziness, do not stop it on the strength of this article. Bring the guideline recommendation to your clinician and ask how it applies to you.

Does BPPV go away on its own, and does it come back?

Yes to both, which is the paradox of a condition that is benign but persistent.

Left untreated, most episodes of BPPV resolve within weeks to a few months. The crystals either drift back out of the canal on their own or, according to one theory, gradually dissolve in the canal fluid. Natural-history studies suggest the median untreated duration is a few weeks for the posterior canal and shorter for the horizontal canal. This is why the guideline lists observation as a legitimate choice: for someone who finds the attacks tolerable, waiting is not negligent, merely slower.

The catch is recurrence. Even after successful repositioning, the crystal bed that shed the debris is still fragile. Pooled data suggest roughly 15 percent of people have a repeat episode within a year, and estimates of recurrence over five years range from about a third to half, depending on the population. Cleveland Clinic puts the long-term figure as high as 50 percent. People whose BPPV followed head trauma, and those with coexisting inner-ear disease, migraine or low vitamin D, sit at the higher end.

Recurrence is not failure. A repeat episode usually responds to the same maneuver as quickly as the first, and people who have been shown the technique often recognize the warning signs early. Mayo Clinic frames follow-up visits as a way to confirm the maneuver worked and to plan for future episodes rather than as an admission that treatment failed.

So the accurate answer to the search query is this: a given episode almost always goes away, with or without treatment, and treatment makes it go faster. The tendency to get BPPV may not go away, and living well with it means having a plan for the next time rather than hoping there will not be one.

BPPV exercises: what helps between episodes and what doesn't

The phrase covers two very different things, and conflating them is a common source of frustration.

Repositioning maneuvers, covered above, are done a small number of times to move crystals and are not exercises in the everyday sense. Once the positional test is negative, there is no evidence that repeating the Epley daily prevents future episodes, and the guideline does not recommend it as prophylaxis.

Vestibular rehabilitation is different. It is a structured program, usually supervised by a physical therapist, of eye, head and balance movements designed to help the brain recalibrate after any inner-ear disturbance. For people whose BPPV has resolved but who are left with lingering unsteadiness, especially older adults, a course of rehabilitation has moderate trial support for improving balance confidence and reducing falls. It does not target crystals; it targets the nervous system’s response to them.

Brandt-Daroff exercises occupy an awkward middle ground. Developed in 1980 as a habituation routine, they involve lying down alternately on each side several times a day. Head-to-head trials found them clearly less effective than the Epley for clearing posterior-canal BPPV, and the guideline no longer positions them as a first choice. Some clinicians still suggest them for people who cannot tolerate repositioning or whose affected side cannot be determined.

What genuinely helps between episodes is practical rather than athletic. Get out of bed slowly, in two stages. Use a second pillow if lying flat provokes symptoms, not because it prevents recurrence but because it makes a recurrence less startling. Keep a clear path from bed to bathroom, since the first steps after an attack are the riskiest for a fall. And keep your clinician’s instructions for the maneuver somewhere you can find them at six in the morning.

Common myths about BPPV, corrected

Myth: BPPV is a sign of a stroke or brain tumor. The overwhelming majority of brief, position-triggered vertigo with a classic positional test is inner-ear BPPV. Central causes exist and matter, which is why the red-flag list in the next section exists, but the presence of the typical nystagmus pattern is strongly reassuring.

Myth: You can diagnose your own side from a video. The side that feels worse when you lie on it is often the affected side, but not always, and horizontal-canal BPPV can produce vertigo on both sides. A clinician watching your eyes during the test is the reliable method.

Myth: You must sleep sitting up for two days after the maneuver. This was standard advice for years. Randomized trials tested it and found no benefit, and the guideline recommends against routine post-maneuver restrictions.

Myth: Motion-sickness pills fix BPPV. They may ease nausea. They do not move crystals, do not shorten the episode and carry fall-risk side effects, which is why the guideline recommends against routine use.

Myth: BPPV means something is wrong with your neck. Neck stiffness can accompany it, because people hold their heads rigidly to avoid triggering attacks, but the problem originates in the inner ear. Neck manipulation is not a treatment for BPPV and is not recommended.

Myth: Once treated, it is gone for good. The episode resolves; the predisposition often does not. Recurrence over several years is common and manageable.

Myth: A viral home maneuver is risky for everyone. The opposite error. For most people, a clinician-taught maneuver at home is safe and effective. The risk lies in skipping the diagnosis and in the small group with neck, spine, eye or vascular conditions that make head-hanging positions inadvisable.

When to see a doctor about vertigo

Any first episode of vertigo deserves a medical assessment, even when it fits BPPV perfectly. The diagnosis is straightforward for a clinician and nearly impossible to make with certainty on your own, and the treatment depends on getting it right.

Seek emergency care immediately, by calling emergency services rather than driving, if vertigo comes with any of the following:

• A sudden severe headache unlike any you have had before
• Double vision, loss of vision, or difficulty speaking or swallowing
• Weakness, numbness or clumsiness in the face, an arm or a leg
• Inability to stand or walk without falling, when previously you could
• Confusion, fainting, or a seizure
• Chest pain, an irregular heartbeat, or shortness of breath
• Vertigo that is constant and unrelenting rather than triggered by position

These can indicate a stroke, particularly one affecting the back of the brain, which can mimic inner-ear vertigo. The NHS and MedlinePlus both list them as reasons for urgent evaluation.

Arrange a routine but prompt appointment if you have new hearing loss or ringing in one ear alongside vertigo, if a maneuver performed by a clinician has failed twice, if attacks recur frequently despite treatment, if you have had a recent head injury, or if unsteadiness is causing falls or near-falls at home.

Talk to your prescribing clinician before changing any medication in response to what you have read here. If you take a vestibular suppressant, a blood pressure medicine or a sedative and you are experiencing dizziness, the interaction between the drug and the condition is a medical judgment, not a do-it-yourself one.

The best outcome from a BPPV visit is usually the simplest: a test, a maneuver, a few minutes of spinning, and a person who walks out steadier than they walked in.

Frequently asked questions

How do you get rid of BPPV fast?

The quickest reliable approach is a clinician-performed repositioning maneuver, such as the Epley, after a positional test identifies the affected ear. Trials show about 80 percent of people improve within one or two sessions. Some clinicians then teach a home version to repeat if symptoms return, but self-diagnosing the side from a video is the main reason home attempts fail.

What triggers BPPV attacks?

Individual attacks are triggered by head movements that shift the affected canal relative to gravity: lying down, rolling over in bed, sitting up, tipping the head back, or bending forward. The underlying crystal displacement is often unexplained, but head injury, prior inner-ear inflammation, prolonged time lying with the head tilted, migraine and older age are recognized associations.

Does BPPV go away on its own?

Usually, yes. Most untreated episodes settle within weeks to a few months as the crystals drift out of the canal or dissolve. The guideline lists observation as an acceptable option for people who prefer to wait. Treatment with a repositioning maneuver resolves symptoms much faster, and the tendency to have future episodes can persist even after a full recovery.

What medications are used to treat BPPV?

Vestibular suppressants such as meclizine, dimenhydrinate or diazepam have been used to reduce nausea and spinning, but the 2017 clinical guideline recommends against prescribing them routinely for BPPV because they do not move the crystals or shorten the episode and can increase drowsiness and fall risk. A clinician may use one briefly in specific situations; that decision belongs to them.

Can I do the Epley maneuver at home safely?

Many people can, after a clinician has confirmed the diagnosis, identified the affected side and shown them the sequence. Trials of self-administered maneuvers show good results, though slightly lower than clinician-performed ones. People with severe neck or spine problems, recent neck surgery, retinal detachment or significant vascular disease should not attempt it without individual medical advice.

What is the difference between BPPV and other kinds of vertigo?

BPPV produces brief spinning, under a minute, provoked by specific head positions, with no hearing change. Vestibular neuritis causes continuous vertigo for days. Ménière’s disease brings episodes lasting hours with hearing loss, tinnitus and ear fullness. Vestibular migraine is variable and often accompanied by headache or light sensitivity. Stroke-related vertigo typically comes with neurological signs such as weakness or double vision.

Are BPPV exercises the same as the Epley maneuver?

No. The Epley is a repositioning maneuver done a few times to move crystals, not a daily exercise. Brandt-Daroff exercises are a repeated habituation routine that trials found less effective than repositioning. Vestibular rehabilitation is a therapist-guided program for lingering unsteadiness after the crystals have settled, and it targets the brain’s balance processing rather than the crystals themselves.

Do I need an MRI for BPPV?

Not usually. The clinical guideline recommends against routine imaging when the history and positional test are classic, because an MRI cannot show the crystals and does not change treatment. Imaging is reserved for atypical features: nystagmus that does not fit a canal pattern, neurological symptoms, repeated maneuver failure, or a history suggesting another cause.

Why does BPPV keep coming back?

Because the maneuver clears the displaced crystals but does not repair the crystal bed that shed them. Roughly 15 percent of people have a recurrence within a year and estimates over five years run from about a third to half. Recurrence is more common after head trauma and in people with inner-ear disease, migraine or low vitamin D, and it generally responds to the same maneuver.

Should I sleep sitting up after the Epley maneuver?

Current guidance says no. Sleeping upright, avoiding lying on the treated side and wearing a soft collar were standard advice for years, but randomized trials found these restrictions did not improve outcomes, and the 2017 guideline recommends against imposing them routinely. Your clinician may still give individual advice based on how you responded during the maneuver.
