How Do ENT Specialists Find the Cause of Vertigo? Timing, Triggers and Hearing Clues

The spinning starts before she has even lifted her head from the pillow. For twenty seconds the bedroom ceiling wheels around like a slow carousel, her stomach lurches, and then it stops as suddenly as it began. By the time she reaches the kitchen she feels almost normal, which is exactly why she has put off mentioning it for a month.

Scenes like this arrive in ear, nose and throat clinics every week, and the striking thing is how little equipment the first appointment usually needs. When people ask how is vertigo diagnosed, they often picture scanners and wires. Most of the time the answer sits in three plainer questions: how long does a spell last, what brings it on, and has your hearing changed?

Those three clues, read together with a few bedside eye-movement tests, sort the great majority of cases into a small number of well-understood patterns. This article walks through that reasoning the way a specialist actually applies it.

Why the first question is not "are you dizzy?" but "what does it feel like?"

Dizziness is one of the vaguest words in medicine. It covers light-headedness before fainting, unsteadiness on the feet, a woolly-headed feeling from a poor night’s sleep, and the very specific illusion that you or the room is moving. Only the last of these is vertigo, and separating it from the rest is the first job of any consultation.

Vertigo is a false sense of motion. People describe the room turning, the floor tilting, or their own body being pulled sideways. It comes from a mismatch between what the balance organs in the inner ear report and what the eyes and joints report, and the brain responds with nausea and a strong urge to hold still. According to MedlinePlus, most vertigo arises from a problem in the inner ear or the nerve that connects it to the brain, while a smaller share comes from the brain itself.

That is why a specialist will spend the opening minutes gently pinning down the sensation. Did the world actually move, or did you feel faint? Did it feel like a boat deck, or like being spun on an office chair? Did your vision jump? People are sometimes surprised at how insistent this questioning is, but it matters. Light-headedness on standing points toward blood pressure and the heart; an unsteady gait without spinning points toward nerves, joints or vision; true spinning points squarely at the vestibular system, the network of inner-ear canals, nerves and brain pathways that keeps you oriented in space.

The earliest spells people report tend to be brief and positional, most often when rolling over in bed or tipping the head back to look at a high shelf. Others recall a single dramatic day of relentless spinning with vomiting. Which of those two stories you tell already narrows the field considerably, before any test is performed.

How is vertigo diagnosed? The three clues specialists weigh first

Ask an experienced ENT or neuro-otology clinician how vertigo is diagnosed and you will hear a version of the same triad: timing, triggers, hearing. The framework is laid out in the widely cited review by Strupp and Brandt in Deutsches Ärzteblatt International, and it underpins guidance from the NHS and Mayo Clinic alike.

Timing means the duration of a single episode, not how many weeks the problem has bothered you. Seconds, minutes, hours and days each suggest different mechanisms, because the inner ear and the brain fail in characteristically timed ways.

Triggers are the circumstances that reliably start a spell. Rolling in bed, looking up, bending forward, a loud sound, straining, a migraine aura, or nothing at all. “Nothing at all” is itself a useful answer, since spontaneous attacks behave differently from positional ones.

Hearing clues cover new hearing loss, ringing (tinnitus) and a sense of fullness or pressure in one ear. The cochlea, which handles hearing, sits beside the balance organs and shares their fluid and blood supply. When hearing changes alongside vertigo, the problem is usually in that shared inner-ear space. When hearing is untouched, attention shifts to the balance nerve, the brain, or the tiny crystals inside the semicircular canals.

The elegance of this approach is that the clues cross-check one another. Spells lasting under a minute, triggered by head position, with normal hearing, form one tight cluster. Attacks lasting hours, arriving without warning, with muffled hearing and roaring tinnitus in one ear, form another. Constant spinning for two days with vomiting and no hearing change forms a third. Only when the pattern refuses to fit is the heavier machinery of testing and imaging brought in.

This is also why the notes you make at home before an appointment carry real diagnostic weight. A week of jotted times and circumstances can save a month of uncertainty.

Timing: seconds, minutes, hours or days tell very different stories

Duration is the single most discriminating clue, so clinicians press hard on it. People tend to overestimate how long a spell lasted because the aftermath of nausea and unsteadiness blurs into the spinning itself. Specialists therefore ask you to time only the actual sensation of movement.

Seconds to under a minute. Brief, intense spinning that fades in under a minute is the signature of benign paroxysmal positional vertigo, usually shortened to BPPV. Mayo Clinic describes BPPV episodes as typically lasting less than one minute. Loose calcium carbonate crystals, called otoconia, drift from their normal resting place into a semicircular canal and slosh with gravity when the head moves, briefly fooling the brain into sensing rotation.

Minutes to an hour or two. Attacks in this window, especially with headache, light sensitivity or a personal history of migraine, raise the possibility of vestibular migraine, a migraine variant in which dizziness rather than pain is the main feature. Transient interruptions of blood flow to the back of the brain can also cause short spells, which is one reason this duration is examined with particular care in older adults or those with cardiovascular risk factors.

Twenty minutes to several hours. The NHS notes that attacks of Ménière’s disease commonly last from 20 minutes to several hours. Ménière’s is a disorder of fluid pressure in the inner ear, and the attacks usually come with hearing change in one ear, which links directly to the hearing clue discussed below.

Days. Continuous, severe vertigo that persists for more than a day and then slowly eases over one to several weeks points toward vestibular neuritis or labyrinthitis, in which the balance nerve or the whole inner ear is inflamed, most often after a viral illness. The NHS describes symptoms usually easing over a few weeks as the brain compensates.

A constant, low-grade unsteadiness that never truly spins and never fully stops is a different animal again, often reflecting anxiety, medication effects, visual problems or a chronic vestibular condition. It is diagnosed by a different route and rarely by positional testing alone.

Triggers: what sets it off, and why "nothing" is a meaningful answer

Once duration is settled, the specialist wants the circumstances. Vertigo that is reliably provoked by a specific movement behaves differently from vertigo that ambushes you while sitting still, and the distinction reorganizes the entire list of possibilities.

Head position relative to gravity. Rolling over in bed, lying back at the dentist, tilting the head to look up, bending to tie shoes. These are the classic BPPV triggers, because each one moves displaced crystals through a canal. Cleveland Clinic and Mayo Clinic both list changes in head position as the defining provocation. Importantly, BPPV does not usually strike while walking on level ground with the head upright.

Spontaneous onset. Attacks that start unprovoked, often with a warning sense of ear fullness or a change in tinnitus, suggest Ménière’s disease or vestibular migraine. Spontaneous attacks that arrive with headache, visual aura or heightened sensitivity to light and sound lean toward migraine; those with one-sided hearing change lean toward Ménière’s.

Pressure or sound. Vertigo brought on by coughing, straining, lifting or loud noises is uncommon but distinctive. It hints at an abnormal opening between the inner ear and its surroundings, and it usually prompts specialist imaging rather than a bedside diagnosis.

Standing up. Dizziness that arrives only on rising from a chair or bed, without true spinning, is more likely to be a fall in blood pressure than an ear problem. Clinicians often check lying and standing blood pressure to rule this in or out early.

Head movement in any direction. Feeling worse with every head turn during a multi-day episode is typical of vestibular neuritis, because the brain is receiving lopsided signals from the two ears and every movement amplifies the mismatch. This is a general aggravation rather than a specific trigger, and the specialist will ask you to draw that line.

People often apologize that they cannot identify a trigger. There is no need. “It just happens” is a legitimate, informative answer that actively narrows the differential.

Hearing clues: tinnitus, fullness and one-sided hearing loss

The third clue is the one people most often forget to mention, because a slightly muffled ear feels trivial next to a spinning room. To a specialist it is anything but trivial. Hearing and balance share an organ, a fluid system and a nerve bundle, so hearing symptoms are a map reference for where the trouble lies.

Three hearing clues are asked about directly. Tinnitus is the perception of ringing, roaring or hissing with no external sound. Aural fullness is a sense of pressure or blockage in the ear, as if descending in an aircraft. Hearing loss, particularly if it fluctuates and affects one ear, is the most significant of the three.

When these appear together with attacks of vertigo lasting hours, the pattern points toward Ménière’s disease. The NHS describes the combination of vertigo, tinnitus, hearing loss and a feeling of pressure deep inside the ear as the characteristic cluster, and early on the hearing typically dips during attacks and recovers between them. Because the hearing loss in Ménière’s tends to affect low frequencies first, an audiogram, a formal hearing test that plots sensitivity across pitches, can reveal a shape that supports the diagnosis even between attacks.

Vertigo with sudden, marked hearing loss in one ear and no attack history is treated as more urgent, since sudden sensorineural hearing loss is time-sensitive and the combination can occasionally point to labyrinthitis or, rarely, a vascular event. This is one of the situations in which the specialist will move quickly to testing rather than watchful waiting.

Equally telling is the absence of hearing change. BPPV leaves hearing untouched. Vestibular neuritis, by definition, spares the cochlea; if hearing is also lost during the same illness the label changes to labyrinthitis. Vestibular migraine rarely produces sustained hearing loss. A person who reports intact hearing has, in effect, ruled out a whole branch of the diagnostic tree in a single sentence.

What actually happens at the appointment: the Dix-Hallpike test and bedside eye exams

After the history, the specialist looks at your eyes. That sounds odd for an ear problem until you know that the balance organs are hard-wired to the eye muscles. When the inner ear misfires, the eyes drift and snap back in a rhythmic pattern called nystagmus, and the direction and timing of that drift reveal which structure is at fault.

The Dix-Hallpike test is the centerpiece for suspected BPPV. You sit on the examination couch with your head turned about 45 degrees to one side. The clinician supports your head and lays you back briskly so that your head hangs slightly below the level of the couch, still turned. They then watch your eyes for up to a minute. If crystals have drifted into the posterior canal on that side, a short burst of spinning and a characteristic upward-and-rotating nystagmus appears after a brief delay, then fades. The test is repeated on the other side. Mayo Clinic describes this as the standard bedside way to confirm BPPV and identify the affected ear.

The test is unpleasant for the few seconds it provokes vertigo, and clinicians warn you beforehand. It is not dangerous, but people with severe neck problems or recent neck surgery should mention them, since a modified positioning may be used.

The supine roll test checks the horizontal canal by turning the head side to side while lying flat. The head-impulse test involves the clinician turning your head rapidly a few degrees while you fix your gaze on their nose; a corrective flick of the eyes suggests a weak balance nerve on one side. Gaze testing looks for nystagmus when you stare to the left, right, up and down, and a cover test checks whether one eye sits higher than the other when the other is covered.

Some clinics use video goggles that block your vision and record eye movements, which makes subtle nystagmus far easier to see. The whole sequence usually takes a matter of minutes, and for a clear-cut case of BPPV it can be followed straight away by a repositioning maneuver in the same visit.

Peripheral or central: the HINTS exam and why the distinction matters most

Behind every vertigo assessment sits one overriding question. Is this coming from the ear (peripheral) or from the brain (central)? Peripheral causes are far more common and, though miserable, are not dangerous in themselves. Central causes, chiefly stroke affecting the brainstem or cerebellum, are uncommon but can be missed precisely because they sometimes mimic an inner-ear problem.

For someone who arrives with continuous, ongoing vertigo, clinicians often use a bedside sequence known by the acronym HINTS: Head Impulse, Nystagmus, Test of Skew. The logic runs as follows. A peripheral problem, such as vestibular neuritis, typically produces an abnormal head-impulse test (a corrective eye flick), nystagmus that beats in one direction regardless of where you look, and no vertical misalignment of the eyes. A central problem often produces the reverse: a normal head-impulse test despite severe vertigo, nystagmus that changes direction with gaze, or one eye sitting higher than the other when uncovered.

Research summarized in the NIH-indexed literature and in Strupp and Brandt’s review indicates that, in experienced hands, this three-part exam can be more sensitive than early brain imaging for detecting stroke in people with acute continuous vertigo, since small brainstem strokes may not show on a scan in the first hours. That is a reassurance in one sense and a caution in another: a normal early scan does not, by itself, close the question.

Alongside the eye tests, the specialist checks for other central signs: new double vision, slurred speech, facial numbness, a limb that will not do what it is told, or an inability to stand or walk at all. Peripheral vertigo makes walking hard and lurching; it does not usually make walking impossible.

The distinction carries practical weight. A peripheral diagnosis leads to repositioning maneuvers, rehabilitation and time. A suspected central cause leads to urgent imaging and a different team. Getting this fork right is the heart of the job, and it is why a thorough specialist will not skip the eye examination even when the story sounds like a classic ear problem.

Which tests come next, and who is usually asked to wait before a scan

A common expectation is that vertigo will be investigated with an MRI straight away. In practice, imaging is a second- or third-line step, reserved for specific situations. The NHS and Mayo Clinic both describe a stepwise approach in which the history and bedside tests carry most of the load.

Hearing tests come early when hearing symptoms are present. A pure-tone audiogram measures the softest sound you can detect at each pitch in each ear and is the standard way to document the fluctuating low-frequency loss of Ménière’s or the sudden loss of labyrinthitis.

Vestibular function tests are ordered when the bedside findings are ambiguous or when planning rehabilitation. Videonystagmography records eye movements with infrared goggles during positional, gaze and warm-and-cool air (caloric) stimulation of each ear, quantifying how strongly each balance organ responds. Video head-impulse testing measures the same reflex assessed at the bedside but with a sensor. Vestibular evoked myogenic potentials test other parts of the balance organ using sound clicks and neck or eye muscle recordings.

Brain imaging, usually MRI, is generally reserved for people with central signs on examination, with new one-sided hearing loss that has not recovered, with vertigo that persists in an unusual pattern, or with risk factors for stroke. It is also used when a growth on the balance nerve needs to be excluded.

Who is usually asked to wait? Someone with a textbook BPPV story and a positive Dix-Hallpike test rarely needs anything more than treatment and a follow-up check. Someone whose acute vertigo is settling day by day, with reassuring eye tests, is often observed rather than scanned. Someone whose only complaint is dizziness on standing is directed toward blood pressure and heart assessment instead.

Sequencing tests this way is not about withholding care. Ordering an MRI for a clear case of BPPV does not make the diagnosis more accurate; it simply delays the repositioning maneuver that would have resolved the spinning. A good specialist chooses tests to answer a question, not to fill a form.

BPPV vs vestibular neuritis vs Ménière's: how the common causes are told apart

Putting the three clues together, the most frequent inner-ear diagnoses separate cleanly on paper, even if individual patients sometimes blur the lines. The table summarizes typical patterns described by Mayo Clinic, the NHS and the Strupp and Brandt review.

Condition	Typical episode length	Usual trigger	Hearing change	Key bedside finding
Benign paroxysmal positional vertigo (BPPV)	Under a minute	Head position change (rolling in bed, looking up)	None	Positive Dix-Hallpike or roll test
Vestibular neuritis	Days, easing over weeks	Spontaneous, often after viral illness; worse with any head movement	None (if hearing is lost, it is called labyrinthitis)	One-directional nystagmus, abnormal head-impulse test
Ménière’s disease	Twenty minutes to several hours	Spontaneous, sometimes preceded by ear fullness	Fluctuating low-frequency loss, tinnitus, fullness in one ear	Audiogram changes; exam often normal between attacks
Vestibular migraine	Minutes to hours, occasionally days	Spontaneous; migraine triggers such as sleep loss or stress	Usually none sustained	Exam often normal; history of migraine
Central cause (e.g., brainstem or cerebellar stroke)	Continuous, often sudden	Spontaneous	Occasionally, if blood supply to the ear is shared	Direction-changing nystagmus, normal head-impulse, skew, inability to walk

Mayo Clinic identifies BPPV as the most common cause of vertigo, and it becomes more frequent with age, most often appearing in people over 60. Vestibular neuritis is the usual explanation for a single dramatic multi-day episode. Ménière’s is diagnosed less often than people fear; many who suspect it turn out to have vestibular migraine, which shares the spontaneous attacks but lacks the progressive hearing loss.

Two diagnoses can coexist. People with Ménière’s or vestibular neuritis appear more prone to developing BPPV afterwards, because damage to the inner ear can free crystals. A specialist who finds a positive Dix-Hallpike test in someone with a known chronic condition will treat the BPPV on its own terms.

What the days and weeks after diagnosis usually look like

Once a label is attached, the natural next question is what the following weeks hold. The answer depends heavily on the diagnosis, and honest ranges matter more than reassurance.

After a BPPV diagnosis. The specialist usually performs a canalith repositioning maneuver, most often the Epley maneuver, in clinic. This is a sequence of four or five timed head positions that walks the loose crystals out of the canal and back into the chamber where they belong. Mayo Clinic notes that BPPV can also settle on its own over weeks or months, but repositioning typically shortens that considerably. Some people feel a little off-balance for a day or two afterwards. A follow-up check confirms whether the Dix-Hallpike test has become negative or whether the maneuver needs repeating. Recurrence is common over the following years, and many clinics teach a home version once the affected canal is known.

After vestibular neuritis. The first few days are the hardest. The NHS describes symptoms usually easing over a few weeks as the brain learns to compensate for the weak side, a process called vestibular compensation. Getting up and moving as soon as it is safe accelerates this, which is why clinicians discourage prolonged bed rest once the vomiting has settled. Some people are referred for vestibular rehabilitation, a structured program of eye, head and balance exercises supervised by a physiotherapist.

After a Ménière’s or vestibular migraine diagnosis. These are episodic, so the weeks ahead are about pattern-tracking rather than recovery from a single event. A diary of attacks, hearing changes, sleep, stress and diet helps the team judge whether a preventive strategy is working. Hearing may be re-tested at intervals.

After a normal workup. Some people leave with tests that show nothing structural. That is not a dead end. Persistent dizziness without a positional or inner-ear cause is often addressed with rehabilitation and attention to sleep, anxiety and medication review, and the team will say what they are watching for.

What happens if vertigo is left untreated?

This is one of the most searched questions about vertigo, and the honest answer has two halves.

The reassuring half: the common inner-ear causes are not progressive in the way people fear. BPPV does not damage the ear; the crystals sit harmlessly in the canal until they dissolve, are reabsorbed or drift back, which is why Mayo Clinic notes it can resolve unaided over weeks to months. Vestibular neuritis leaves the brain to compensate, and most people regain steady function whether or not they see a specialist, though rehabilitation can speed and smooth the process. Untreated vertigo from these causes does not lead to deafness, stroke or brain damage.

The less reassuring half concerns consequences rather than the disease itself. Untreated BPPV in an older adult means unpredictable spinning when turning in bed or reaching upward, and that translates into falls. Falls carry their own risks of fractures and loss of confidence. Persistent unsteadiness after vestibular neuritis, if the person avoids movement out of fear, can harden into a chronic pattern of dizziness driven partly by anxiety and reduced activity, which is harder to unpick later than the original illness. Ménière’s disease, left without any management plan, tends to continue its attacks and its stepwise hearing loss regardless, so a diagnosis at least allows hearing to be monitored and protected where possible.

The most serious risk of “waiting it out” is the small chance that what feels like ear vertigo is actually a central problem. Vertigo of brain origin is uncommon, but it is the reason the red-flag signs later in this article deserve to be taken seriously rather than filed under “probably just my ears.”

So the practical message is not that untreated vertigo is dangerous in itself, but that undiagnosed vertigo denies you the specific fix that might exist, exposes you to falls, and leaves the rare central cause unexamined. Those are good reasons to be seen, and poor reasons to be frightened.

Can you get rid of vertigo? What treatment actually depends on

“How can I get rid of vertigo?” is the question behind every appointment, and the only honest reply is that it depends entirely on which of the patterns above you have. Treatment is chosen for the mechanism, not for the sensation, which is why a diagnosis has to come first.

Repositioning maneuvers are the direct answer for BPPV. The Epley and Semont maneuvers move the crystals out of the canal by sequencing head positions with gravity. They are performed by a clinician who knows which canal and which side is involved, and they can be repeated if the first attempt does not clear the symptoms. Treating BPPV with medication alone is not recommended, because pills cannot move crystals.

Vestibular rehabilitation is the mainstay for lingering unsteadiness after vestibular neuritis and for many chronic dizziness syndromes. Exercises that deliberately provoke mild dizziness in a controlled way train the brain to recalibrate. Johns Hopkins and Cleveland Clinic both describe this as a first-line approach for persistent vestibular symptoms.

Medicines play a limited and specific role. In the first days of a severe acute episode, a clinician may prescribe a short course of a vestibular suppressant, such as an antihistamine or antiemetic class medicine, to blunt nausea and spinning enough to allow eating and sleeping. These are typically used briefly, because prolonged use can slow the very compensation the brain needs to do. For Ménière’s disease and vestibular migraine, preventive strategies, which can include dietary measures and preventive medicine classes chosen by the treating team, aim to reduce the frequency of attacks rather than abolish a single one. Whether, when and how any of these is used is a decision for your prescribing clinician.

Lifestyle and safety measures matter for everyone: rising slowly, keeping a light on at night, clearing trip hazards, not driving during active spells, and staying active rather than retreating to the sofa.

What vertigo does not respond to is guesswork. A repositioning maneuver performed for the wrong condition does nothing; rehabilitation started before an active Ménière’s attack pattern is controlled is frustrating. The route to feeling better runs through the diagnosis, every time.

What people often get wrong about vertigo diagnosis

Several misunderstandings surface so often in clinic that they deserve direct correction.

“Vertigo is a diagnosis.” It is a symptom, like cough or fever. Being told you “have vertigo” is a description of the sensation, not an explanation. The diagnostic work is in finding what is producing it.

“It must be a brain problem because it is so severe.” Intensity is a poor guide. Inner-ear vertigo can be violently disabling, with vomiting and complete inability to stand steadily, while some central causes are surprisingly mild. Clinicians judge by eye findings and neurological signs, not by how awful it feels.

“An MRI will tell me what is wrong.” For BPPV, Ménière’s, vestibular neuritis and vestibular migraine, MRI is usually normal. It is an excellent tool for excluding certain things, not for confirming the common ear conditions, which are diagnosed clinically.

“Vertigo means fear of heights.” The film title has muddied the language. Height-related dizziness is a visual and anxiety phenomenon; medical vertigo is the illusion of movement from a vestibular cause.

“I should keep still until it passes.” Sensible for the first day of an acute attack, counterproductive afterwards. Movement is the raw material of vestibular compensation, and prolonged rest slows recovery.

“Motion-sickness tablets treat the cause.” They suppress the symptom temporarily. Nothing in a tablet repositions crystals, restores a nerve or changes inner-ear fluid dynamics. Long-term reliance on them without a diagnosis can leave the underlying problem unaddressed and delay compensation.

“Low iron, dehydration or my neck is the cause.” Each can contribute to dizziness, but true spinning vertigo with positional triggers or hearing change nearly always has a vestibular explanation, and pinning it on something else risks missing a treatable inner-ear problem.

“If I had a stroke I would know.” Small strokes in the balance centers of the brain can present with isolated vertigo and imbalance. This is exactly why the red-flag signs below exist, and why clinicians examine eyes and gait even in people who look otherwise well.

Questions to ask your care team

A vertigo consultation moves fast, and it helps to arrive with questions rather than trying to recall them once the Dix-Hallpike test has left you queasy. The following are the ones specialists say they are glad to be asked.

• Based on my timing, triggers and hearing, which condition do you think is most likely, and what would change your mind?
• Did my eye tests show a peripheral or a central pattern, and what did you look for to decide?
• Do I need a hearing test, vestibular function testing or imaging, and what specific question would each one answer?
• If this is BPPV, which canal and which side is affected, and can a repositioning maneuver be done today?
• Should I try a home repositioning exercise, and if so, can you show me how it is done for my particular canal?
• How long would you typically expect my symptoms to take to settle, and at what point should I come back if they have not?
• Is vestibular rehabilitation appropriate for me, and how do I access it?
• If a medicine is being suggested, what is it for, how long is it intended to be used, and how will we know whether it is helping?
• Which signs should prompt me to seek urgent care rather than wait for my next appointment?
• Is it safe for me to drive, work at height or return to sport, and what should I avoid in the meantime?
• Could any of my current medicines be contributing to dizziness?
• How likely is this to come back, and what should I do if it does?

Bringing a written timeline of your episodes, a list of current medicines, and a note of any hearing changes turns these questions into a productive conversation. If you can, bring someone with you; the person who watched you during an attack may remember details about your eyes, your speech or your walking that you could not observe yourself.

The answers to these questions, and every decision about tests and treatment, belong with the team examining you. This article explains the reasoning; it cannot replace the examination.

When to call your doctor: vertigo red flags

Most vertigo is an inner-ear problem that is unpleasant rather than dangerous. A small proportion is not, and the features below are the ones the NHS, Mayo Clinic and stroke guidance highlight as reasons to seek emergency care immediately rather than book a routine appointment.

Seek emergency help right away if vertigo comes with:

• A new, severe headache unlike any you have had before, or headache with neck stiffness
• Double vision, loss of vision in part of your visual field, or eyes that will not move together
• Slurred or jumbled speech, or difficulty understanding others
• Weakness, numbness or clumsiness in the face, an arm or a leg, especially on one side
• Difficulty swallowing, or a new hoarse voice
• Inability to stand or walk at all, even with support, or a sudden severe change in coordination
• Chest pain, palpitations, shortness of breath or fainting
• A high fever, a stiff neck or a recent head injury
• Sudden new hearing loss in one ear

These signs point toward the brain, the heart or an acute infection rather than the inner ear, and time matters for all three. Do not drive yourself.

Contact your doctor promptly, though not necessarily as an emergency, if: spells are recurring and interfering with daily life; you have fallen or nearly fallen; hearing in one ear is fluctuating; vertigo has continued beyond a few weeks without improvement; symptoms have returned after a period of settling; or you are unsure whether what you feel is vertigo or light-headedness. Older adults, people who live alone, and those taking several medicines are usually asked to be seen sooner rather than later, because the fall risk from even benign vertigo is higher.

Finally, trust your own sense that something is different. Clinicians would far rather examine a person with a harmless positional problem than miss the one whose story hid a central cause. The exam takes minutes; the information it yields can change everything.

Frequently asked questions

How is vertigo diagnosed at a first appointment?

Through a detailed history and a bedside examination of your eye movements and balance. The clinician asks how long each spell lasts, what provokes it and whether your hearing has changed, then performs positional tests such as the Dix-Hallpike maneuver and a head-impulse test while watching for nystagmus. Hearing tests, vestibular recordings or imaging are added only when the pattern is unclear or red-flag signs are present.

What is the Dix-Hallpike test and does it hurt?

It is a positional test for BPPV in which you sit with your head turned about 45 degrees and are laid back quickly so your head hangs slightly below the couch while the clinician watches your eyes. It does not hurt, but if crystals are in the tested canal it triggers a short burst of spinning lasting well under a minute. That brief discomfort is precisely what confirms the diagnosis and identifies the side to treat.

What are the first signs of vertigo?

Most people first notice a brief spinning sensation when rolling over in bed, lying back or looking up, sometimes with nausea, that fades in under a minute. Others experience a single prolonged episode of relentless spinning with vomiting after a viral illness, or a spontaneous attack lasting hours with a muffled, ringing ear. Which of these stories fits you is one of the first things a clinician will want to hear.

What are the red flags for vertigo?

Vertigo accompanied by a sudden severe headache, double vision, slurred speech, facial or limb weakness or numbness, trouble swallowing, inability to stand or walk at all, chest pain, fainting, fever with a stiff neck, recent head injury or sudden one-sided hearing loss needs emergency assessment. These features suggest the brain, heart or an infection rather than the inner ear, and they should not wait for a routine appointment.

What is the difference between BPPV vs vestibular neuritis?

Duration and trigger separate them. BPPV causes repeated spells lasting under a minute, set off by specific head positions, with normal hearing and a positive Dix-Hallpike test. Vestibular neuritis causes a single continuous episode of severe spinning lasting days, worsened by any head movement, usually after a viral illness, and eases over a few weeks as the brain compensates. BPPV is treated with repositioning maneuvers; neuritis is managed with early movement and, where needed, rehabilitation.

Will I need an MRI to diagnose vertigo?

Usually not. The common inner-ear causes, including BPPV, vestibular neuritis, Ménière’s disease and vestibular migraine, are diagnosed clinically and typically produce a normal MRI. Imaging is generally reserved for people whose eye examination suggests a central cause, who have unexplained one-sided hearing loss, whose pattern does not fit any inner-ear condition, or who carry stroke risk factors. Your specialist will explain what specific question a scan is meant to answer.

What causes vertigo most often?

Benign paroxysmal positional vertigo, in which loose calcium crystals drift into a semicircular canal of the inner ear and move with gravity when the head changes position. Mayo Clinic identifies it as the most common cause and notes it becomes more frequent with age. Vestibular neuritis, Ménière’s disease and vestibular migraine account for most of the remainder, with brain-related causes being uncommon but important to exclude.

How can I get rid of vertigo?

It depends on the cause, which is why diagnosis comes first. BPPV is treated with a repositioning maneuver such as the Epley, performed for the specific canal involved. Lingering imbalance after vestibular neuritis responds to vestibular rehabilitation exercises. Ménière’s disease and vestibular migraine are managed with preventive strategies chosen by your treating team. Medicines that suppress spinning are used briefly for acute episodes and do not address the underlying mechanism.

What will happen if vertigo is left untreated?

The common inner-ear causes do not damage the brain or hearing on their own, and BPPV and vestibular neuritis often settle over weeks to months. The real risks are falls, particularly in older adults, chronic dizziness driven by avoidance of movement, unmonitored hearing loss in Ménière’s disease, and the small chance that a central cause goes unrecognized. A diagnosis gives you access to the specific treatment that exists for your pattern.

Why does the specialist care whether my hearing has changed?

Because hearing and balance share an organ, a fluid system and a nerve bundle. New hearing loss, tinnitus or ear fullness alongside vertigo points toward the inner-ear chamber shared by both, as in Ménière’s disease or labyrinthitis. Normal hearing points instead toward the balance nerve, the crystals in the canals or the brain. Mentioning even a slightly muffled ear can redirect the entire assessment.
