TL;DR – Vertigo or Stroke: The HINTS Exam Explained
Vertigo or stroke HINTS exam? The 60-second HINTS exam (Head Impulse, Nystagmus, Test of Skew) is more accurate than MRI scans at detecting brainstem strokes. Key findings:
Understanding this vertigo or stroke HINTS exam difference can be lifesaving in emergency situations.
- Abnormal Head Impulse Test (eyes move away with head movement) = Inner ear problem (good news, not stroke)
- Normal Head Impulse Test + continuous vertigo = RED FLAG for brainstem stroke (seek emergency care immediately)
- Direction-changing or vertical nystagmus = Brain problem (stroke sign)
- Skew deviation (one eye higher) = Brainstem stroke confirmed
When to go to ER: Continuous vertigo + any of the “Rule of the Ds” (double vision, slurred speech, difficulty swallowing, lack of coordination, hoarseness).
When to see PRIME ENT Center: Brief position-triggered spinning (likely BPPV) or stable vertigo with normal neurological exam.

Vertigo or Stroke? The 60-Second Test Every Patient Should Know
Understanding the Symptom That Terrifies Millions
Vertigo and dizziness are among the most common reasons patients seek emergency medical care, accounting for approximately 3.3% of all emergency department visits worldwide. While most cases of sudden, violent spinning are caused by benign inner ear conditions, a small but significant percentage—between 4% and 15%—are caused by a life-threatening stroke in the brainstem or cerebellum. This article explains how to distinguish between an inner ear emergency and a “brain attack” using a specific, 60-second bedside examination called the HINTS exam, which has proven to be more accurate than early MRI scans at identifying strokes in patients experiencing continuous vertigo.experiencing continuous vertigo
What Is Vertigo? Defining the Sensation
Vertigo is defined as a false sensation of self-motion or the illusion that the visual surroundings are spinning, tilting, or flowing. It is a symptom, not a diagnosis—arising when there is a critical mismatch between the vestibular, visual, and somatosensory systems in maintaining balance.
Normally, your inner ears (the labyrinth) send equal and opposite tonic signals to the brain, creating a balanced perception of stillness. When one ear’s signals are suddenly reduced—whether by inflammation of the vestibular nerve, infection, or an interruption of blood flow to the brain—the balance centers perceive this asymmetry as a continuous rotation. The brain then generates compensatory eye movements and reports the sensation of spinning, even though the environment is perfectly still.
Common Misperceptions:
- Dizziness ≠ Vertigo. Dizziness is a vague feeling of unsteadiness; vertigo is the specific sensation of spinning.
- Vertigo ≠ Fear of Heights. Fear of heights is acrophobia; vertigo is neurological.
Anatomy of Balance: The Vestibular System Explained
To understand why vertigo occurs, one must understand the balance system’s architecture:
The Inner Ear (Labyrinth):
The inner ear houses the vestibular organ, which contains:
- Three semicircular canals (anterior, posterior, lateral) that detect rotational movement
- Otolith organs (utricle and saccule) that detect linear acceleration and gravity
- Vestibular nerve (the vestibulocochlear nerve or CN VIII) that carries these signals to the brain
The Vestibular Nuclei and Brainstem:
Signals from the inner ear are processed in the brainstem’s vestibular nuclei, which integrate input from both ears, the eyes (via the visual system), and proprioceptors (position sensors in the body). The brainstem also controls the cerebellum, which fine-tunes balance and coordination.
The Critical Role of the Vestibulo-Ocular Reflex (VOR):
When you move your head, the VOR automatically moves your eyes in the opposite direction to keep your visual gaze fixed. This reflex is mediated by the vestibular nerve and brainstem pathways. When this reflex is disrupted—either at the nerve level (peripheral) or in the brainstem/cerebellum (central)—vertigo results.
Peripheral Vertigo vs. Central Vertigo: The Critical Distinction
Medical professionals classify vertigo into two categories based on the location of the lesion:
Peripheral Vertigo (Inner Ear Problem)
Originates in the inner ear or the vestibular nerve, distal to the brainstem.
Common Causes:
- Benign Paroxysmal Positional Vertigo (BPPV) – brief episodes triggered by head position changes; accounts for 50% of all vertigo cases
- Vestibular Neuritis – inflammation of the vestibular nerve, often viral; presents with continuous vertigo for days
- Labyrinthitis – inflammation of the labyrinth (inner ear), often viral or bacterial
- Menière’s Disease – inner ear fluid imbalance; associated with hearing loss and tinnitus
Characteristic Features:
- Vertigo typically lasts seconds to minutes (BPPV) or days to weeks (neuritis)
- Nausea and vomiting are common
- Hearing loss is usually not present (except in Menière’s)
- No neurological deficits (no weakness, no slurred speech, no double vision)
- The patient can usually walk or stand, even if unsteady
Central Vertigo (Brain Problem)
Originates in the brainstem, cerebellum, or cerebral pathways.
Most Dangerous Cause:
- Posterior Circulation Stroke – infarction affecting the vertebral or basilar arteries that supply the brainstem and cerebellum; accounts for 15–20% of all strokes but represents 4–15% of vertigo presentations
Other Central Causes:
- Brainstem hemorrhage
- Cerebellar infarction or hemorrhage
- Tumors or mass lesions in the posterior fossa
- Multiple sclerosis (demyelinating plaques in the brainstem)
- Vertebral artery dissection
Characteristic Features:
- Vertigo is often accompanied by other neurological signs
- Severe imbalance; the patient may not be able to sit or stand unassisted (ataxia)
- Associated symptoms: diplopia (double vision), dysarthria (slurred speech), dysphagia (difficulty swallowing), dysmetria (lack of coordination)
- May present without focal weakness initially, making diagnosis challenging
The Problem with Early MRI Scans: Why Clinical Exam Matters
Many patients and even some physicians assume that an immediate brain MRI is the most reliable way to rule out a stroke. However, this assumption is dangerously flawed.
The False-Negative Problem:
Diffusion-weighted imaging (DWI) MRI can be false-negative in up to 50% of patients with small brainstem strokes if the scan is performed within the first 24 to 48 hours of symptom onset. This is because:
- Small infarcts in the brainstem are difficult to visualize on early scans
- The delayed diffusion of water molecules means the ischemic lesion may not yet be apparent
- By the time the lesion becomes visible (24–48 hours later), critical treatment windows (thrombolysis) have closed
Why the HINTS Exam is Superior in the Acute Setting:
- Takes 60 seconds to perform
- Requires no imaging equipment
- Has 100% sensitivity and 96% specificity for detecting acute brainstem strokes in the emergency department
- Guides immediate clinical decision-making and treatment initiation
The vertigo or stroke HINTS exam has become the gold standard in emergency medicine and neurology for differentiating peripheral from central causes of acute continuous vertigo and making rapid clinical decisions.
The HINTS Exam: The 60-Second Life-Saver
The HINTS protocol (Head Impulse, Nystagmus, Test of Skew) is a three-step clinical assessment designed to differentiate an acute peripheral vestibulopathy (like vestibular neuritis) from a central stroke. Each component uses the patient’s eye movements to “read” the health of the balance system.
Step 1: The Head Impulse Test (HIT)
This is considered the most important and most sensitive component of the HINTS exam.
How It’s Performed:
- The patient fixates on a stationary target (usually the examiner’s nose or a dot on the wall)
- The examiner rapidly rotates the patient’s head 10–20 degrees to one side (typically 0.5–1 second duration)
- The examiner observes whether the patient’s eyes remain fixed on the target or require a catch-up movement
Peripheral Finding (Inner Ear Problem):
- The eyes move away from the target with the head
- A quick “catch-up” saccade (rapid eye jump) is required to refixate on the target
- This indicates that the vestibular reflex (VOR) is abnormal or absent because the inner ear or nerve is damaged
- An abnormal HIT is reassuring in a patient with continuous vertigo because it suggests a peripheral, non-stroke cause
Central Finding (Stroke):
- The eyes remain fixed on the target despite rapid head movement
- No catch-up saccade is required
- The patient’s gaze remains stable
- A normal HIT in a patient with continuous vertigo is a major “red flag” for a central stroke because it means the inner ear and vestibular nerve are intact—the problem is in the brainstem
- This counterintuitive finding—”normal” eye reflex but pathological vertigo—is the hallmark of central brainstem pathology
Clinical Pearl: A normal HIT + continuous vertigo = high suspicion for stroke until proven otherwise.
Step 2: Nystagmus (Involuntary Eye Movements)
Nystagmus is a rhythmic, involuntary to-and-fro movement of the eyes. The pattern and direction of these movements provide crucial clues to the lesion’s location.
How It’s Assessed:
- The examiner observes the patient’s eyes at rest, in straight gaze, and as the patient looks right, left, up, and down
- Particular attention is paid to whether the nystagmus changes direction based on gaze direction
Peripheral Finding (Inner Ear Problem):
- The nystagmus is “unidirectional”—it always beats in the same direction regardless of where the patient looks
- For example, if the patient has right vestibular neuritis, the nystagmus may always beat to the left (away from the damaged ear)
- The fast phase of the nystagmus (the quick component) points away from the side of the lesion
Central Finding (Stroke):
- The nystagmus is “direction-changing” or “gaze-evoked”—it beats to the right when looking right and to the left when looking left
- This pattern suggests brainstem involvement in oculomotor control pathways
- Alternatively, a vertical or rotatory nystagmus (oscillation up-down or twisting) is highly suggestive of brainstem or cerebellar pathology
- Purely vertical nystagmus is almost never seen in peripheral vertigo
Clinical Pearl: Direction-changing or vertical nystagmus in a vertiginous patient = stroke until proven otherwise.
Step 3: Test of Skew (Vertical Eye Alignment)
This test assesses whether there is vertical misalignment of the eyes, which would indicate brainstem dysfunction.
How It’s Performed:
- The patient fixates straight ahead on a target
- The examiner alternately covers and uncovers each eye while observing for vertical displacement
- When the cover is removed, any corrective eye movement (up or down) indicates misalignment
Peripheral Finding (Inner Ear Problem):
- The eyes remain vertically aligned
- No corrective movement is needed when the cover is removed
- This is because peripheral vestibular lesions affect the horizontal (side-to-side) balance system primarily
Central Finding (Stroke):
- One eye will be higher than the other (skew deviation)
- When the cover is removed from the higher eye, it will jump downward to refixate
- When the cover is removed from the lower eye, it will jump upward to refixate
- Skew deviation specifically indicates a brainstem lesion affecting the pathways that control vertical eye alignment
Clinical Pearl: Skew deviation = brainstem pathology confirmed.
HINTS Plus: The Fourth Step
To enhance the vertigo or stroke HINTS exam further, clinicians have added a fourth component to this diagnostic protocol: testing for acute hearing loss.
Rationale:
- The internal auditory artery (IAA) supplies both the labyrinth and the cochlea (hearing organ)
- A stroke affecting the IAA causes both vertigo and unilateral hearing loss simultaneously
- If a patient presents with sudden continuous vertigo AND sudden hearing loss in one ear (confirmed by Weber and Rinne tests), this suggests an IAA stroke—a precursor to a more extensive brainstem infarct
What to Look For:
- Sudden sensorineural hearing loss (inner ear type, not conductive) on one side
- Normal ear canal (ruling out cerumen impaction or otitis externa)
- New-onset vertigo in the same timeframe
Clinical Significance: Vertigo + acute unilateral sensorineural hearing loss = immediate neuroimaging and stroke evaluation indicated.
Adult vs. Pediatric Presentations: Special Considerations for Children
While vertigo in adults often signals a stroke risk, pediatric vertigo presents differently and carries different differential diagnoses.
Key Differences in Children:
Eustachian Tube Anatomy:
Children have shorter, more horizontal Eustachian tubes compared to adults. This makes them more susceptible to:
- Acute otitis media with secondary labyrinthitis (labyrinthitis ossificans if severe)
- Serous otitis (fluid behind the eardrum) causing imbalance
- These conditions are typically not life-threatening but require attention to prevent hearing loss
BPPV in Children:
- BPPV is much less common in children than in adults
- When it does occur, it may follow head trauma or viral illness
- The HINTS exam remains useful but must be adapted for the child’s ability to cooperate
Vestibular Neuritis in Pediatrics:
- Common in children aged 4–14 years, often following a viral upper respiratory infection
- Presents with acute vertigo, nausea, vomiting, and imbalance lasting 3–7 days
- Usually benign with good prognosis if no stroke features are present
Stroke in Pediatric Populations:
- Pediatric posterior circulation strokes are rare but serious
- Associated with:
- Arterial dissection (from trauma, connective tissue disorders)
- Congenital heart disease with paradoxical embolism
- Thrombophilia (bleeding/clotting disorders)
- Vasculitis or vasculopathy
- The HINTS exam applies equally to children and should be performed if continuous vertigo is present
- The key difference is that stroke in a child is less common, so peripheral causes are more likely—but the exam remains equally sensitive for ruling in or ruling out stroke
Red Flags Requiring Immediate Imaging in Children:
- Head impulse test abnormal + HINTS Plus features (hearing loss)
- Direction-changing or vertical nystagmus
- Skew deviation
- Associated neurological deficits (weakness, speech changes, incoordination beyond balance)
- History of head trauma with delayed vertigo onset
- Known cardiac disease or clotting disorder + acute vertigo
The “Rule of the Ds”: Identifying Urgent Stroke Symptoms
While vertigo can occasionally be an isolated symptom of brainstem stroke, the presence of additional neurological signs dramatically increases stroke probability. These are remembered as the “Rule of the Ds”:
| Sign | Definition | What It Means |
|---|---|---|
| Diplopia | Double vision | Cranial nerve III, IV, or VI dysfunction (brainstem pathways) |
| Dysarthria | Slurred or difficult speech | Dysarthria clunica (cerebellar) or dysarthria from bulbar weakness |
| Dysphagia | Difficulty swallowing | Cranial nerve IX and X involvement (medullary stroke) |
| Dysmetria | Lack of coordination in limbs; inability to touch nose or perform rapid alternating movements | Cerebellar dysfunction |
| Dysphonia | Hoarseness or voice changes | Vagal nerve involvement |
Clinical Rule: If a patient experiences continuous vertigo + any one of the Ds (or multiple Ds), the risk of a brainstem or cerebellar stroke is extremely high. This mandates immediate emergency evaluation.
Additional Red Flags: When Vertigo Demands Emergency Evaluation
Beyond the “Rule of the Ds,” the following situations require immediate emergency department evaluation:
- Inability to Sit or Stand Unassisted
- Profound ataxia (loss of coordination) such that the patient cannot maintain balance even when seated
- Indicates severe brainstem or cerebellar involvement
- Nausea and Vomiting So Severe That Oral Intake Is Impossible
- Risk of dehydration and aspiration
- May indicate posterior fossa stroke with elevated intracranial pressure
- Headache + Vertigo
- Especially occipital or neck pain
- Suggests possible vertebral artery dissection (stroke precursor)
- Sudden Onset During Sleep or Upon Waking
- Peripheral causes (BPPV, neuritis) typically develop gradually or with positional triggers
- Sudden nocturnal onset suggests stroke
- Progressive Worsening Over Minutes to Hours
- Peripheral vertigo often stabilizes; progressive worsening suggests central lesion
- Stroke symptoms evolve as the area of ischemia expands
- Loss of Consciousness or Altered Mental Status
- Indicates brainstem or cerebellar involvement with secondary effects
- Requires immediate intervention
Summary Table: Peripheral vs. Central Vertigo at a Glance
| Feature | Peripheral (Inner Ear) | Central (Stroke) |
|---|---|---|
| Head Impulse Test | Abnormal; catch-up saccade present | Normal; no catch-up saccade |
| Nystagmus | Unidirectional (same direction always) | Direction-changing or vertical |
| Test of Skew | Normal; eyes remain level | Abnormal; one eye higher than other |
| Hearing Loss | Absent (unless Menière’s) | May occur if internal auditory artery involved |
| Balance Ability | Can usually walk or stand, even if unsteady | Profound ataxia; cannot sit unassisted |
| Duration of Vertigo | Seconds to minutes (BPPV) or days-weeks (neuritis) | Hours to days; progressive |
| Associated Symptoms | Usually none beyond nausea/vomiting | Diplopia, dysarthria, dysphagia, dysmetria |
| Prognosis Without Treatment | Usually self-limited; recovery in weeks | Potentially catastrophic; requires urgent treatment |
When to Seek Help: A Dual-Pathway Guide
Understanding how to use the vertigo or stroke HINTS exam is critical to determine whether you need emergency or urgent care. This knowledge is essential for appropriate resource allocation and optimal patient outcomes.
Seek IMMEDIATE Emergency Medical Attention (Call 911 or Go to Emergency Department) If:
- First-ever episode of acute, continuous vertigo lasting more than 1 hour (until you can rule out stroke)
- HINTS exam findings concerning for stroke:
- Normal head impulse test + continuous vertigo
- Direction-changing or vertical nystagmus
- Skew deviation
- Acute hearing loss with vertigo
- Vertigo + any of the “Rule of the Ds” (diplopia, dysarthria, dysphagia, dysmetria, dysphonia)
- Severe imbalance; unable to sit or stand unassisted
- Vertigo + severe headache, especially occipital or neck pain
- Vertigo + unconsciousness or altered mental status
- Progressive worsening of vertigo over hours
- Recurrent episodes of vertigo in an elderly patient or patient with vascular risk factors (hypertension, diabetes, smoking, prior stroke)
What to Tell the Emergency Dispatcher:
“I am experiencing sudden, spinning dizziness that started [time] and is continuous. I [may/may not] have double vision, slurred speech, or difficulty walking. Please send an ambulance.”
At the Emergency Department:
- Alert the team that you have acute continuous vertigo
- Request the HINTS exam to be performed
- Inform them of any associated neurological symptoms
- Ask specifically about stroke protocol evaluation
Seek Urgent Outpatient Evaluation at PRIME ENT Center Hardoi (Within 24–48 Hours) If:
- Brief episodes of positional vertigo (seconds, triggered by head movement) → Likely BPPV; treatable with repositioning maneuvers
- Gradual-onset vertigo developing over hours to days, now stable, with normal HINTS exam findings
- Suggests peripheral vestibulopathy (neuritis, labyrinthitis)
- Requires specialist assessment for hearing tests and vestibular function testing
- Recurrent episodes of vertigo with known BPPV or Menière’s Disease history
- Vertigo accompanied by ear discharge, hearing loss, or chronic ear drainage
- May suggest infectious labyrinthitis or cholesteatoma
- Mild imbalance without continuous spinning, able to walk and function
- Pediatric vertigo in a child with normal neurological examination
- Requires assessment for otitis media, Eustachian tube dysfunction, or post-viral labyrinthitis
How to Schedule at PRIME ENT Center Hardoi:
- Call our clinic to request an urgent appointment
- Describe your symptoms: onset, duration, associated ear symptoms, hearing changes
- Bring any recent hearing tests or imaging reports
- Dr. Prateek Porwal and Dr. Harshita Singh specialize in vestibular disorders and can perform formal balance testing, videonystagmography (VNG), and caloric testing
What Urgent Outpatient Evaluation Includes:
- Complete history and neurological examination
- Formal HINTS protocol assessment
- Audiometry and Weber/Rinne tests (to assess hearing)
- Dix-Hallpike maneuver and supine roll tests (if BPPV is suspected)
- Romberg test and gait assessment
- Referral for advanced testing if needed (MRI, vestibular function tests)
Why Early Specialist Evaluation Matters
Even if your vertigo is peripheral (from the inner ear), timely diagnosis and treatment prevent complications:
- Hearing Preservation: Some causes of peripheral vertigo (labyrinthitis, sudden sensorineural hearing loss) can progress to permanent hearing loss if not treated promptly
- Vestibular Rehabilitation: Physical therapy can significantly speed recovery and reduce disability in vestibular neuritis
- Prevention of Falls: Elderly patients with untreated vertigo face high risk of falls, fractures, and long-term disability
- Accurate Diagnosis: A specialist can differentiate benign conditions from rare but serious causes like perilymphatic fistula or superior semicircular canal dehiscence
Key Takeaways for Patients and Families
- These key points about the vertigo or stroke HINTS exam will help you understand when to seek emergency care:Vertigo is common, but continuous vertigo requires rapid evaluation to rule out stroke.
- The HINTS exam is a simple, 60-second clinical test that is more accurate than early MRI for detecting brainstem strokes.
- The presence of an abnormal head impulse test is reassuring; a normal head impulse test + continuous vertigo is a red flag for stroke.
- Any vertigo accompanied by double vision, slurred speech, difficulty swallowing, or severe imbalance requires emergency evaluation.
- Pediatric vertigo is usually benign but should still be evaluated by an ENT specialist to rule out infection or hearing loss.
- If you experience brief, position-triggered vertigo, you likely have BPPV and can be seen urgently at PRIME ENT Center; if you have continuous vertigo, go to the emergency department first.

Vertigo ya Stroke? Yeh 60-Second Test Har Patient Ko Pata Hona Chahiye
Samajhiye: Yeh Symptom Jo Crores Ko Darr Dilaata Hai
Duniya bhar mein, vertigo aur dizziness ke wajah se hazar hazaar log har din emergency room mein jaate hain. Doctors kehte hain ki out of every 100 visits, 3-4 log sirf dizziness aur spinning ke wajah se aate hain. Ab suno—jyadatar cases mein yeh sirf inner ear ka problem hota hai aur bilkul safe hota hai. But 4 se 15 percent cases mein, yeh ek life-threatening condition hota hai—brain mein stroke.
Toh question yeh hai: Kaise pata chalega ki mera dizziness inner ear se hai ya brain mein stroke?
Answer: Ek 60-second exam jishe HINTS kehte hain. Yeh exam sirf 1 minute mein maloom kar deta hai ki danger hai ya nahi. Aur amazing baat yeh hai ki yeh exam MRI se bhi zyada accurate hai stroke pakadne mein!
Vertigo Kya Hota Hai? Samajhiye Asan Bhashaa Mein
Vertigo = duniya ghumti hui lag rahi hoti hai.
Imagine karo ki tum bed se uthte ho aur ek second mein sab kuch spin karne lagte ho—yeh hi vertigo hai. Lekin yeh sirf dimag ka illusion hota hai; duniya asli mein nahi ghumti.
Humari body ke paas ek balance system hota hai jo inner ear (kaan ke andar) mein hota hai. Yeh system brain ko bolti hai, “tu kitna tilt hai? tu kitna rotate kar raha hai?” Jab yeh system proper kaam nahi karti, brain ko galatfehmi hoti hai aur samjh jaata hai ki sab kuch ghumti ja rahi hai.
Samjho isko aise:
- Imagine tum train mein baithe ho aur ghar ka ground sab kuch uper-neech lag raha hai
- Lekin sach mein train hi move kar rahi hai, ground nahi
- Yeh hi vertigo ka concept hai—body galatfehmi mein hai ke outside world move kar raha hai, par haqiqat mein sirf balance system mein galti hai
Kaan Ke Andar Kya Hota Hai? Balance System Ka Magic
Humari inner ear ek chhoti si factory ki tarah hoti hai jo balance ko control karti hai:
Semicircular Canals: Teen pipe-jaisa structure jo rotate (spin) detect karti hai
Otolith Organs: Yeh gravity aur up-down movement detect karti hai
Vestibular Nerve: Yeh sabhi signals brain ko bhejti hai
Jab yeh system theek se kaam karti hai, tum bilkul normal feel karte ho. Lekin jab:
- Infection hota hai (viral labyrinthitis)
- Nerve swell ho jaati hai (neuritis)
- Blood supply block hoti hai (stroke)
…toh balance system ko wrong signals dilte hain aur spinning lag lagti hai.
Do Prakar Ka Vertigo: Kaan Se Ya Brain Se?
Doctors 2 groups mein divide karte hain:
Group 1: Peripheral Vertigo (Kaan Se Problem)
Matlab: Inner ear ya kaan ke nerve mein problem hai.
Common Reasons:
- BPPV (Benign Paroxysmal Positional Vertigo) – jab tum head move karte ho to ek second spinning lag jaati hai; yeh subse common hota hai
- Vestibular Neuritis – kaan ke nerve ko virus se inflammation; 2-3 din continuous dizziness hoti hai
- Labyrinthitis – inner ear mein infection; aksar viral hota hai
- Menière’s Disease – kaan mein fluid imbalance; plus hearing loss bhi hota hai
Achha News:
- Yeh conditions bilkul benign hote hain (dangerous nahi)
- Few days-weeks mein theek ho jaate hain
- Nausea aur vomiting ho sakti hai, par baaki body theek hoti hai
- Speech, vision, sab kuch normal rehta hai
Group 2: Central Vertigo (Brain Se Problem)
Matlab: Brain ke baramda (brainstem) ya cerebellum mein problem hai.
Sabse Khatra: STROKE in the brain!
Brain ko blood supply vertebral aur basilar arteries deti hain. Jab inme se kisi mein blood clot ban jaata hai ya bleed hota hai, toh:
- Vertigo bilkul alag hota hai
- Baaki body mein bhi weakness, speech problems, double vision—ye sab hote hain
- Yeh medical emergency hota hai
MRI Scan Pehle Kyun Theek Nahi Hai? Science Ke Baare Mein Jaan Lo
Aksar log sochte hain: “Mujhe immediately MRI kar do!”
Lekin yaha bada trick hai:
Jab brain ke paas blood supply roke jaati hai, toh MRI scanner ko 24-48 hours tak problem dikh nahi paata!
Brain ka ischemic (oxygen-starved) area itna chhota aur deep hota hai ki early scan mein miss ho jaata hai. By the time MRI mein dikhi (24+ hours), treatment window close ho chuki hoti hai. Yeh isliye dangerous hai!
HINTS exam isliye better hai:
- Sirf 60 seconds mein
- Zero radiation
- 100% accurate stroke detect karne mein
- Immediately treatment start kar sakte ho
HINTS Exam: The 60-Second Brain Test
HINTS = Head Impulse, Nystagmus, Test of Skew
Yeh 3-step test hai. Har step sirf eye movements dekhti hai. Bas.
Step 1: Head Impulse Test (HIT)
Kaise Hota Hai:
- Patient ko ek point (ya examiner ke nose) pe dekh-o
- Examiner quickly patient ka head ek side ko rotate karti hai
- Dekh-na ki kya eyes target pe lagti hain ya away jaati hain
Agar Inner Ear Problem Hai:
- Eyes away chli jaayengi head ke saath
- Phir quickly back jump karenge target pe
- Iska matlab: inner ear ko problem hai, brain theek hai ✓ (Good news!)
Agar Brain Stroke Hai:
- Eyes bilkul steady rehti hain target pe
- No catch-up movement
- Iska matlab: inner ear normal hai, lekin brain mein problem hai = DANGER! 🚨
Remember: Normal HIT + continuous spinning = STROKE red flag!
Step 2: Nystagmus (Eye Jumps)
Nystagmus = aankhen bar-bar back-and-forth jump kar rahi hain
Doctors dekhte hain: Ye jumps kaunse direction mein hai?
Inner Ear Problem:
- Jumps hamesha ek hi direction mein (fixed)
- Jab patient left dekhe, phir bhi jump same direction mein
- Jab patient right dekhe, phir bhi same direction mein
- = GOOD news, probably peripheral problem
Brain Stroke:
- Jumps different directions mein based on where patient dekhta hai
- Right dekho → right direction jump
- Left dekho → left direction jump
- Ya vertical jumps (up-down) → yeh brainstem stroke ka classic sign hai
- = DANGER, stroke possible 🚨
Pro Tip: Vertical aankhen up-down jump kar rahi ho + dizziness = 99% chance stroke hai!
Step 3: Test of Skew (Eyes Level Hain Ya Nahi)
Kaise Hota Hai:
- Patient straight aankhe aage dekhe
- Doctor ek-ek eye ko cover-uncover karti hai
- Dekhna ki kya ek aankh doosri se higher hai ya sama level mein hai
Inner Ear Problem:
- Dono aankhen same level mein
- Sab normal
Brain Stroke:
- Ek aankh doosri se higher position mein
- Jab cover hata-o, eye jump karti hai down/up
- Iska matlab: brainstem mein problem hai = STROKE sign 🚨
Step 4: Hearing Loss Check (HINTS Plus)
Recent research ne ek aur step add kiya:
Kya kaan mein sudden hearing loss hai?
Agar vertigo + sudden hearing loss ek ear mein = blood supply block ho sakti hai brain ke paas = stroke ka sign = immediate imaging chahiye!
Bacchon Mein Vertigo: Alag Hota Hai!
Bachche ko vertigo stroke ke wajah se hona bilkul rare hota hai. Zyada-tar:
- Inner ear infection (otitis media)
- Viral labyrinthitis
- BPPV (head trauma ke baad)
Lekin phir bhi HINTS exam same apply hota hai. Agar:
- Normal HIT + continuous spinning
- Direction-changing nystagmus
- Skew deviation
- Neurological weakness
…toh bachche ko bhi immediate imaging aur stroke evaluation chahiye.
Baaki baare mein: Bachche mein vertigo usually good prognosis hota hai. ENT specialist ko dikhao within 24 hours.
Yaad Rakhne Wali Baatein: Rule of the Ds
Jab brain mein stroke hota hai, toh sirf vertigo nahi hota. Aur symptoms bhi hote hain:
| Symptom | Matlab |
|---|---|
| Diplopia | Double vision (2 cheezein dikh rahi hain) |
| Dysarthria | Slurred speech (speech unclear, mumbling) |
| Dysphagia | Swallowing difficult (nigalne mein problem) |
| Dysmetria | Coordination loss (haath-paon mein lack of control) |
| Dysphonia | Voice change (awaz mein hoarseness) |
Golden Rule: Agar vertigo + ek bhi “D” = IMMEDIATE EMERGENCY!
Aur Bhi Red Flags: Kab Emergency Jao?
- Bilkul stand/sit nahi kar pao – ataxia (balance bilkul off)
- Itna nausea ki kuch khaa-pee nahi pao – dehydration ka khatra
- Neck/head mein severe pain + vertigo – artery tear possible
- Raat mein sleep se uthkar suddenly vertigo – stroke typical sign
- Vertigo worse and worse ho raha hai 1-2 hours mein – progressive = dangerous
- Unconscious hone lago ya dimag foggy ho – serious
Quick Decision Guide: Emergency vs. Urgent Clinic
STRAIGHT TO EMERGENCY IF:
- Continuous vertigo + normal head impulse test
- Direction-changing or vertical nystagmus
- Skew deviation
- Vertigo + double vision / slurred speech / weak limbs
- Can’t sit/stand alone
- Vertigo + severe head pain
- Age 50+, high BP, diabetes, smoking history
URGENT VISIT TO PRIME ENT CENTER (24-48 HOURS) IF:

वर्टिगो या स्ट्रोक? यह 60-सेकंड टेस्ट हर रोगी को जानना चाहिए
समझिए: लाखों लोगों को डराने वाली समस्या
दुनिया भर में हर दिन हजारों लोग आपातकालीन विभाग में जाते हैं। उनकी शिकायत सिर्फ एक होती है: “सब कुछ घूम रहा है, मुझे बहुत चक्कर आ रहे हैं।”
डॉक्टर कहते हैं कि जो लोग आपातकालीन विभाग में आते हैं, उनमें से 3-4 प्रतिशत सिर्फ इसी समस्या के लिए आते हैं। अच्छी खबर यह है कि ज्यादातर मामलों में यह कान के भीतर की समस्या होती है, जो खतरनाक नहीं होती।
लेकिन भयानक खबर: 4 से 15 प्रतिशत मामलों में, यह जानलेवा स्ट्रोक हो सकता है।
तो सवाल यह है: कैसे पता चले कि यह कान की समस्या है या दिमाग में स्ट्रोक है?
जवाब: एक 60-सेकंड की टेस्ट, जिसे HINTS कहते हैं। यह टेस्ट सिर्फ 1 मिनट में बता देती है कि खतरा है या नहीं। और सबसे अच्छी बात यह है कि यह टेस्ट MRI स्कैन से भी ज्यादा सटीक है स्ट्रोक पकड़ने में!
वर्टिगो क्या है? सरल भाषा में समझिए
वर्टिगो = दुनिया घूम रही है ऐसा महसूस होना।
कल्पना कीजिए: आप बिस्तर से उठते हो और एक सेकंड में सब कुछ घूमने लगता है। आपकी आँखें घूमने वाली दुनिया को देखती हैं, आपका दिमाग कहता है, “सब कुछ घूम रहा है!” यह ही वर्टिगो है। लेकिन सच में—दुनिया घूम नहीं रही। सिर्फ आपका शरीर समझ में गलती कर रहा है।
हमारे शरीर में एक संतुलन प्रणाली होती है जो कान के अंदर होती है। यह प्रणाली मस्तिष्क को बताती है, “तू कितना झुका है? तू कितना घूम रहा है?” जब यह प्रणाली ठीक से काम नहीं करती, मस्तिष्क को गलतफहमी होती है और समझता है कि सब कुछ घूम रहा है।
इसे ऐसे समझो:
- ट्रेन में बैठो और खिड़की से बाहर देखो
- ट्रेन घूमती है, लेकिन तुम्हारा मस्तिष्क सोचता है कि बाहर की दुनिया घूम रही है
- यह ही वर्टिगो का कॉन्सेप्ट है
कान के अंदर क्या होता है? संतुलन प्रणाली का जादू
हमारे कान के अंदर एक छोटी सी फैक्ट्री होती है जो संतुलन को नियंत्रित करती है:
सेमीसर्कुलर कैनाल: तीन पाइप जैसी संरचना जो घूर्णन (spin) को पहचानती है
ओटोलिथ अंग: यह गुरुत्वाकर्षण और ऊपर-नीचे की गति को पहचानता है
वेस्टिबुलर नर्व: यह सभी संकेतों को मस्तिष्क को भेजती है
जब यह प्रणाली बिल्कुल ठीक से काम करती है, आप पूरी तरह सामान्य महसूस करते हो। लेकिन जब:
- संक्रमण होता है (वायरल labyrinthitis)
- नर्व सूज जाती है (neuritis)
- रक्त की आपूर्ति बंद हो जाती है (स्ट्रोक)
…तो संतुलन प्रणाली को गलत संकेत मिलते हैं और घूमने जैसा लगता है।
दो प्रकार का वर्टिगो: कान से या दिमाग से?
डॉक्टर 2 समूहों में विभाजित करते हैं:
समूह 1: परिधीय वर्टिगो (कान से समस्या)
मतलब: कान के अंदर या कान की नर्व में समस्या है।
आम कारण:
- BPPV (Benign Paroxysmal Positional Vertigo) – जब सिर को हिलाते हो तो एक सेकंड घूमना महसूस होता है; यह सबसे आम होता है
- वेस्टिबुलर न्यूराइटिस – कान की नर्व को वायरस से सूजन; 2-3 दिन लगातार चक्कर आते हैं
- Labyrinthitis – कान के अंदर संक्रमण; आमतौर पर वायरल होता है
- मेनियेर्स डिजीज – कान में तरल पदार्थ का असंतुलन; श्रवण हानि भी होती है
अच्छी खबर:
- ये सभी स्थितियाँ बिल्कुल सौम्य होती हैं (खतरनाक नहीं)
- कुछ दिन-हफ्तों में ठीक हो जाती हैं
- मतली और उल्टी हो सकती है, लेकिन बाकी शरीर ठीक रहता है
- बोली, दृष्टि, सब कुछ सामान्य रहता है
समूह 2: केंद्रीय वर्टिगो (दिमाग से समस्या)
मतलब: मस्तिष्क के तने (brainstem) या सेरिबेलम में समस्या है।
सबसे बड़ा खतरा: दिमाग में स्ट्रोक!
मस्तिष्क को रक्त की आपूर्ति vertebral और basilar धमनियों से होती है। जब इनमें से किसी में रक्त का थक्का बन जाता है या खून बहता है, तो:
- वर्टिगो बिल्कुल अलग होता है
- शरीर के अन्य भागों में भी कमजोरी, बोली की समस्या, दोहरी दृष्टि—ये सभी होते हैं
- यह चिकित्सा आपातकाल होता है
MRI स्कैन पहले क्यों सही नहीं है? विज्ञान को समझो
अक्सर लोग सोचते हैं: “मुझे तुरंत MRI करवा दो!”
लेकिन यहाँ एक बड़ी समस्या है:
जब दिमाग के पास रक्त की आपूर्ति रुक जाती है, तो MRI स्कैनर को 24-48 घंटे तक समस्या दिखाई नहीं देती!
दिमाग का缺血 (ऑक्सीजन की कमी वाला) क्षेत्र इतना छोटा और गहरा होता है कि शुरुआती स्कैन में नज़र नहीं आता। जब तक MRI में दिखता है (24+ घंटे), उपचार की खिड़की बंद हो चुकी होती है। यह खतरनाक है!
HINTS टेस्ट इसीलिए बेहतर है:
- सिर्फ 60 सेकंड में
- कोई विकिरण नहीं
- 100% सटीक स्ट्रोक पकड़ने में
- तुरंत उपचार शुरू कर सकते हो
HINTS परीक्षा: 60-सेकंड की दिमाग की टेस्ट
HINTS = Head Impulse, Nystagmus, Test of Skew
यह 3-स्टेप टेस्ट है। हर स्टेप सिर्फ आँख की गतिविधियों को देखता है। बस।
स्टेप 1: हेड इम्पल्स टेस्ट (HIT)
कैसे होता है:
- रोगी को एक बिंदु (या परीक्षक की नाक) पर देखना होता है
- परीक्षक जल्दी से रोगी का सिर एक ओर घुमाता है
- देखना कि क्या आँखें लक्ष्य पर टिकी रहती हैं या दूर चली जाती हैं
अगर कान में समस्या है:
- आँखें सिर के साथ दूर चली जाएँगी
- फिर जल्दी लक्ष्य पर वापस कूद (saccade) करेंगी
- इसका मतलब: कान में समस्या है, दिमाग ठीक है ✓ (अच्छी खबर!)
अगर दिमाग में स्ट्रोक है:
- आँखें बिल्कुल स्थिर रहेंगी लक्ष्य पर
- कोई पकड़-अप आंदोलन नहीं
- इसका मतलब: कान सामान्य है, लेकिन दिमाग में समस्या है = खतरा! 🚨
याद रखो: सामान्य HIT + लगातार घूमना = स्ट्रोक का संकेत!
स्टेप 2: निस्टागमस (आँख की कूदें)
निस्टागमस = आँखें बार-बार आगे-पीछे कूद रही हैं
डॉक्टर देखते हैं: ये कूदें कौन सी दिशा में हैं?
कान की समस्या:
- कूदें हमेशा एक ही दिशा में (स्थिर)
- जब रोगी बाएं देखे, फिर भी कूद उसी दिशा में
- जब रोगी दाएं देखे, फिर भी वही दिशा में
- = अच्छी खबर, संभवतः परिधीय समस्या
दिमाग का स्ट्रोक:
- कूदें अलग-अलग दिशाओं में रोगी के देखने की जगह के अनुसार
- दाएं देखो → दाएं दिशा कूद
- बाएं देखो → बाएं दिशा कूद
- या ऊर्ध्वाधर कूदें (ऊपर-नीचे) → यह ब्रेनस्टेम स्ट्रोक का क्लासिक संकेत है
- = खतरा, स्ट्रोक संभव 🚨
प्रो टिप: ऊर्ध्वाधर आँखें ऊपर-नीचे कूद रही हों + चक्कर = 99% संभावना स्ट्रोक की!
स्टेप 3: स्केव टेस्ट (आँखें स्तर पर हैं या नहीं)
कैसे होता है:
- रोगी सीधे आगे देखे
- डॉक्टर एक-एक आँख को ढकती-खोलती है
- देखना कि क्या एक आँख दूसरी से ऊँची है या समान स्तर पर है
कान की समस्या:
- दोनों आँखें समान स्तर पर
- सब कुछ सामान्य
दिमाग का स्ट्रोक:
- एक आँख दूसरी से ऊँची स्थिति में
- जब कवर हटाओ, आँख ऊपर/नीचे कूद जाती है
- इसका मतलब: ब्रेनस्टेम में समस्या है = स्ट्रोक का संकेत 🚨
स्टेप 4: श्रवण हानि की जांच (HINTS Plus)
हाल के शोध ने एक और स्टेप जोड़ा है:
क्या कान में अचानक श्रवण हानि है?
अगर वर्टिगो + अचानक श्रवण हानि एक कान में = दिमाग के पास रक्त की आपूर्ति रुक सकती है = स्ट्रोक का संकेत = तुरंत इमेजिंग चाहिए!
बच्चों में वर्टिगो: अलग होता है!
बच्चे को स्ट्रोक के कारण वर्टिगो होना बिल्कुल दुर्लभ होता है। अधिकांश:
- कान का संक्रमण (otitis media)
- वायरल labyrinthitis
- BPPV (सिर की चोट के बाद)
लेकिन फिर भी HINTS परीक्षा समान रूप से लागू होती है। अगर:
- सामान्य HIT + लगातार घूमना
- दिशा-परिवर्तन निस्टागमस
- स्केव विचलन
- न्यूरोलॉजिकल कमजोरी
…तो बच्चे को भी तुरंत इमेजिंग और स्ट्रोक मूल्यांकन चाहिए।
बाकी के बारे में: बच्चों में वर्टिगो आमतौर पर अच्छा पूर्वानुमान होता है। ENT विशेषज्ञ को 24 घंटे में दिखाओ।
याद रखने वाली बातें: डीएस का नियम
जब दिमाग में स्ट्रोक होता है, तो सिर्फ वर्टिगो नहीं होता। और भी लक्षण होते हैं:
| लक्षण | मतलब |
|---|---|
| डिप्लोपिया | दोहरी दृष्टि (2 चीजें दिख रही हैं) |
| डिसआर्थ्रिया | अस्पष्ट बोली (बोली अस्पष्ट, गुनगुनाना) |
| डिस्फेजिया | निगलने में कठिनाई (निगलने में समस्या) |
| डिस्मेट्रिया | समन्वय की कमी (हाथ-पैर में नियंत्रण की कमी) |
| डिसफोनिया | आवाज में बदलाव (आवाज में कर्कशता) |
स्वर्णिम नियम: अगर वर्टिगो + एक भी “डी” = तुरंत आपातकालीन!
और भी लाल झंडे: कब आपातकालीन जाओ?
- बिल्कुल खड़े/बैठ नहीं सको – ataxia (संतुलन बिल्कुल गायब)
- इतनी मतली कि कुछ खा-पी नहीं सको – निर्जलीकरण का खतरा
- गर्दन/सिर में गंभीर दर्द + वर्टिगो – धमनी का टूटना संभव
- रात में सोने से जागकर अचानक वर्टिगो – स्ट्रोक का विशिष्ट संकेत
- वर्टिगो खराब और खराब हो रहा है 1-2 घंटे में – प्रगतिशील = खतरनाक
- बेहोश हो रहे हो या दिमाग धुंधला है – गंभीर
तेजी का निर्णय गाइड: आपातकालीन बनाम जरूरी क्लिनिक
सीधे आपातकालीन अगर:
- लगातार वर्टिगो + सामान्य head impulse test
- दिशा-परिवर्तन या ऊर्ध्वाधर निस्टागमस
- स्केव विचलन
- वर्टिगो + दोहरी दृष्टि / अस्पष्ट बोली / कमजोर अंग
- अकेले बैठ/खड़े नहीं हो सको
- वर्टिगो + गंभीर सिरदर्द
- उम्र 50+, उच्च BP, मधुमेह, धूम्रपान का इतिहास
जरूरी PRIME ENT CENTER विजिट (24-48 घंटे) अगर:
- संक्षिप्त स्थिति-ट्रिगर घूमना (कुछ सेकंड) = BPPV
- क्रमिक वर्टिगो (घंटे-दिन), अब स्थिर, सामान्य परीक्षा
- ज्ञात BPPV या मेनियेर्स पुनरावृत्ति
- वर्टिगो + कान का स्राव/श्रवण हानि
- बच्चे में हल्का चक्कर, सामान्य न्यूरोलॉजिकल परीक्षा
PRIME ENT Center Hardoi में कब विजिट करो?
जरूरी नियुक्ति (गैर-आपातकालीन):
- स्थिति-ट्रिगर वर्टिगो (BPPV लक्षण)
- लाल झंडों के बिना स्थिर चक्कर
- श्रवण हानि के साथ चक्कर
- आपातकालीन मूल्यांकन के बाद फॉलो-अप

FAQs
ENGLISH FAQs (20 Questions)
1. What is the main difference between peripheral and central vertigo?
Answer: Peripheral vertigo originates in the inner ear or vestibular nerve and is usually benign (e.g., BPPV, vestibular neuritis). Central vertigo originates in the brainstem or cerebellum and is often life-threatening, especially if caused by stroke. The key distinction is that peripheral vertigo rarely presents with other neurological symptoms, whereas central vertigo frequently accompanies double vision, slurred speech, or severe imbalance.
2. How accurate is the HINTS exam compared to MRI in detecting stroke?
Answer: The HINTS exam has 100% sensitivity and 96% specificity for detecting acute brainstem strokes in the emergency setting, making it more accurate than early MRI scans. Early MRI (within 24–48 hours) can be false-negative in up to 50% of small brainstem stroke cases because the ischemic lesion may not yet be visible. The HINTS exam uses eye movement patterns to detect brainstem dysfunction immediately.
3. What does an abnormal head impulse test indicate?
Answer: An abnormal head impulse test—where the eyes move away from the target with the head and require a catch-up saccade—indicates damage to the inner ear or vestibular nerve. This is a reassuring finding in a patient with continuous vertigo because it suggests a peripheral cause (like vestibular neuritis) rather than a dangerous brainstem stroke.
4. What does a normal head impulse test with continuous vertigo indicate?
Answer: A normal head impulse test in a patient experiencing continuous vertigo is a major red flag for brainstem or cerebellar stroke. This counterintuitive finding means the inner ear and vestibular nerve are intact, but the brainstem—which processes balance signals—is damaged. This patient requires immediate emergency evaluation and neuroimaging.
5. What is nystagmus and how does its pattern help diagnose the cause?
Answer: Nystagmus is a rhythmic, involuntary to-and-fro eye movement. In peripheral vertigo, nystagmus is unidirectional (always beats in the same direction). In central (brainstem) vertigo, nystagmus is direction-changing (beats right when looking right, left when looking left) or purely vertical. Direction-changing or vertical nystagmus is a sign of stroke.
6. What is skew deviation and why is it significant?
Answer: Skew deviation is vertical misalignment of the eyes, where one eye sits higher than the other. This finding is specific to brainstem lesions and is highly suggestive of stroke. When skew deviation is present with vertigo, it is an indication for immediate emergency evaluation and neuroimaging.
7. What is the “Rule of the Ds” and what does it mean for stroke risk?
Answer: The Rule of the Ds refers to five neurological signs that, when present with vertigo, dramatically increase stroke probability: Diplopia (double vision), Dysarthria (slurred speech), Dysphagia (difficulty swallowing), Dysmetria (lack of coordination), and Dysphonia (hoarseness). If a patient has vertigo plus even one “D,” the risk of brainstem or cerebellar stroke is extremely high and requires emergency evaluation.
8. Why is early MRI sometimes false-negative in detecting brainstem strokes?
Answer: Diffusion-weighted imaging (DWI) MRI can be false-negative within the first 24–48 hours because small brainstem infarcts are difficult to visualize early. The ischemic (oxygen-starved) region is often very small and deep within the brainstem. By the time the lesion becomes visible on MRI (24–48 hours later), the critical window for thrombolytic treatment has closed. This is why clinical examination (HINTS) is superior for immediate decision-making.
9. What does “HINTS Plus” include and why is it important?
Answer: HINTS Plus adds a fourth step to the standard HINTS exam: testing for acute sensorineural hearing loss. If a patient presents with sudden vertigo and sudden hearing loss in one ear, this suggests an infarction of the internal auditory artery—a precursor to a larger brainstem stroke. The presence of both findings mandates immediate neuroimaging and stroke evaluation.
10. What is BPPV and how is it different from other causes of vertigo?
Answer: Benign Paroxysmal Positional Vertigo (BPPV) is a common peripheral cause of vertigo triggered by specific head movements, lasting only seconds to minutes. Episodes are brief and position-dependent. Unlike continuous vertigo (which lasts hours to days), BPPV episodes resolve quickly once the head is held still. BPPV has an abnormal head impulse test and is not life-threatening, but should still be evaluated by an ENT specialist.
11. When should I go to the emergency department for vertigo?
Answer: Go to the emergency department immediately if you experience: (1) first-ever acute continuous vertigo lasting more than 1 hour; (2) HINTS exam findings concerning for stroke (normal HIT, direction-changing nystagmus, or skew deviation); (3) vertigo plus any “D” symptom (diplopia, dysarthria, dysphagia, dysmetria, dysphonia); (4) severe imbalance preventing sitting or standing; (5) vertigo with severe headache, especially occipital; or (6) progressive worsening over hours.
12. When can I schedule an urgent outpatient appointment at PRIME ENT Center Hardoi instead of going to the ER?
Answer: Schedule an urgent outpatient appointment at PRIME ENT Center Hardoi (within 24–48 hours) if you have: (1) brief, position-triggered vertigo (likely BPPV); (2) stable, gradual-onset vertigo with a normal neurological examination; (3) recurrent episodes of vertigo with known BPPV or Menière’s Disease; (4) vertigo accompanied by ear discharge or hearing loss; or (5) mild imbalance in a child without red flag symptoms.
13. Is vertigo the same as dizziness?
Answer: No. Vertigo is the specific sensation of spinning or the illusion that the environment is rotating. Dizziness is a vague, non-specific feeling of unsteadiness or lightheadedness. Vertigo indicates a problem with the balance system (inner ear, vestibular nerve, or brainstem); dizziness can result from low blood pressure, anemia, anxiety, or many other causes. Vertigo is more likely to be a neurological emergency.
14. Can a child have a stroke that presents only with vertigo?
Answer: Yes, but pediatric brainstem strokes are rare. Most vertigo in children is peripheral (ear-related) or post-viral. However, if a child has continuous vertigo with HINTS findings suggestive of stroke—such as a normal head impulse test, direction-changing nystagmus, or skew deviation—immediate neuroimaging is indicated. Risk factors in children include arterial dissection, congenital heart disease, thrombophilia, or vasculitis.
15. What is the vestibular system and what does it do?
Answer: The vestibular system is the body’s balance control center, located in the inner ear. It consists of three semicircular canals (detecting rotation), otolith organs (detecting gravity and linear movement), and the vestibular nerve. This system works with the eyes and proprioceptors (position sensors) to maintain balance and visual stability. When the vestibular system malfunctions, vertigo results.
16. Why does exposure to cold air sometimes trigger vertigo?
Answer: Cold air can trigger vertigo through multiple mechanisms: (1) cold exposure may cause vasoconstriction (narrowing of blood vessels) to the vestibular nerve; (2) viral reactivation (dormant herpes simplex virus) may be triggered by cold stress, leading to vestibular neuritis; (3) sudden temperature changes can disrupt the vestibulo-ocular reflex. This is why winter-onset vertigo, though often peripheral and benign, should still be evaluated.
17. What should I do if I suspect a stroke but the emergency team says it’s just inner ear vertigo?
Answer: Ask specifically that the HINTS exam be performed by an experienced neurologist or emergency physician. Request that findings be documented: head impulse test results, nystagmus pattern (unidirectional vs. direction-changing), and skew deviation. If HINTS findings are concerning (normal HIT, direction-changing nystagmus, or skew), demand MRI or CT angiography even if initial imaging was negative. A normal HINTS exam is reassuring; an abnormal HINTS exam requires imaging.
18. Can antibiotics treat vertigo caused by inner ear infection?
Answer: If vertigo is caused by bacterial labyrinthitis (a serious infection), antibiotics combined with other treatments may help, but you must be evaluated by an ENT specialist first. However, most vertigo from viral labyrinthitis or vestibular neuritis is not treated with antibiotics. The role of antibiotics depends on the specific diagnosis (bacterial vs. viral infection, cholesteatoma, etc.). Do not self-treat; see a specialist for proper diagnosis and management.
19. Is vertigo dangerous or just uncomfortable?
Answer: Vertigo can range from mildly uncomfortable (BPPV, which lasts seconds) to life-threatening (brainstem stroke). While most peripheral causes are benign, continuous vertigo of any duration requires evaluation to rule out stroke. Additionally, severe vertigo increases fall risk, especially in elderly patients, leading to fractures and long-term disability. Early specialist evaluation prevents complications and identifies stroke early.
20. How long does it take to recover from peripheral vertigo like vestibular neuritis?
Answer: Recovery timelines vary: (1) BPPV typically resolves within weeks with repositioning maneuvers; (2) vestibular neuritis gradually improves over 2–4 weeks, with most improvement in the first 1–2 weeks; (3) labyrinthitis may take several weeks. Formal vestibular rehabilitation (physical therapy) significantly accelerates recovery and reduces disability. Prognosis is generally excellent if the cause is confirmed as peripheral through HINTS examination and imaging.
HINGLISH FAQs (20 Questions)
1. Peripheral aur Central vertigo mein main difference kya hai?
Answer: Peripheral vertigo kaan se related hota hai aur bilkul safe rehta hai (jaise BPPV). Central vertigo brain se related hota hai aur life-threatening hota hai, especially agar stroke ho. Peripheral vertigo mein usually double vision, slurred speech nahi hote. Central mein ye sab symptoms hote hain.
2. HINTS exam MRI se zyada accurate hai stroke detect karne mein?
Answer: Haan! HINTS exam 100% accurate hai aur 60 seconds mein result dedeta hai. Early MRI (24-48 hours mein) 50% cases mein false negative aata hai kyunke stroke itna chhota aur deep hota hai ki dikh nahi paata. HINTS bas eye movements dekhti hai aur immediately batati hai ki stroke hai ya nahi.
3. Abnormal head impulse test matlab kya hai?
Answer: Abnormal HIT matlab eyes target se away chli jaati hain aur catch-up saccade hoti hai. Iska matlab kaan mein problem hai, brain theek hai. Yeh GOOD news hai kyunke peripheral problem hota hai, stroke nahi.
4. Normal head impulse test continuous vertigo ke saath matlab?
Answer: Yeh RED FLAG hai stroke ka! Normal HIT + continuous spinning = brain problem, inner ear nahi. Iska matlab brainstem mein stroke ho sakta hai. Immediately emergency room mein jao.
5. Nystagmus kya hai aur eye movements kaunsi pattern mein?
Answer: Nystagmus = aankhen bar-bar jump kar rahi hain. Inner ear problem mein: aankhen ek hi direction mein jump karti hain. Brain problem mein: aankhen different directions mein jump karti hain (direction-changing) ya vertical kud-karti hain. Vertical jumps almost 100% stroke ho sakti hain.
6. Skew deviation kya hai aur kyo important hai?
Answer: Skew deviation = ek aankh doosri se zyada oonchi hoti hai. Yeh bilkul brainstem stroke ka sign hai. Agar skew deviation + vertigo, toh immediately hospital jao.
7. Rule of the Ds kya hai?
Answer: 5 warning signs: Diplopia (double vision), Dysarthria (slurred speech), Dysphagia (swallowing problem), Dysmetria (coordination loss), Dysphonia (voice change). Agar vertigo + ek bhi D symptom = stroke probability bilkul high. Emergency evaluation chahiye.
8. Early MRI false-negative kyun ho sakte hain?
Answer: Kyunke brain mein stroke itna chhota aur deep hota hai jo first 24-48 hours mein MRI pe nahi dikh paata. By the time visible ho jaata hai, treatment window close ho chuki hoti hai. Isliye HINTS exam zyada important hai—instant result deta hai.
9. HINTS Plus kya hota hai?
Answer: HINTS Plus = HINTS + hearing loss check. Agar vertigo + sudden hearing loss ek ear mein = internal auditory artery mein stroke ho sakta hai. Urgent imaging chahiye.
10. BPPV kya hota hai aur iska vertigo alag kyun?
Answer: BPPV = brief positional vertigo, sirf kuch seconds, position-triggered. Normal HIT hota hai. Safe hota hai lekin still ENT ko dikhana chahiye. Continuous vertigo se bilkul alag.
11. Emergency room kab jaao?
Answer: (1) Pehli baar continuous vertigo >1 hour, (2) HINTS findings stroke-like, (3) Vertigo + D symptoms, (4) Can’t sit/stand, (5) Severe headache + vertigo, (6) Progressive worsening over hours. Agar ek bhi, straight ER jao.
12. PRIME ENT Center urgent appointment kab lo?
Answer: (1) Brief positional spinning (BPPV), (2) Stable vertigo, normal exam, (3) Known BPPV relapse, (4) Vertigo + ear discharge/hearing loss, (5) Child with mild dizziness, normal neuro exam. 24-48 hours mein appointment lo.
13. Vertigo aur dizziness same hain kya?
Answer: Nahi! Vertigo = spinning sensation, specific. Dizziness = vague unsteadiness. Vertigo = balance system problem (serious). Dizziness = many causes (BP, anemia, anxiety). Vertigo zyada emergency hota hai.
14. Baccha ko stroke ho sakta hai jo sirf vertigo de?
Answer: Haan, lekin bilkul rare. Zyada-tar cases mein ear problem hota hai. Lekin agar HINTS findings stroke-like (normal HIT, direction-changing nystagmus, skew), toh imaging urgent hai. Risk: dissection, heart disease, clotting disorder.
15. Vestibular system kya hota hai?
Answer: Kaan ke andar balance center hota hai. Semicircular canals (rotation detect), otolith organs (gravity detect). Eyes aur body position sensors ke saath kaam karti hai. Jab galti ho jaati hai, vertigo aata hai.
16. Thandi hawa se vertigo kyun trigger hota hai?
Answer: Sardi se: (1) Blood vessels narrow ho jaati hain vestibular nerve ke paas, (2) Virus reactivate ho sakta hai (herpes), (3) Cold exposure vasoconstriction create karti hai. Winter mein vertigo common hota hai.
17. Agar stroke suspect ho lekin ER doctor bolun inner ear hai toh?
Answer: HINTS exam specifically ask karo. Document karao: HIT result, nystagmus pattern, skew deviation. Agar concerning (normal HIT, direction-changing nystagmus), MRI demand karo. Normal HINTS = safe. Abnormal HINTS = emergency imaging.
18. Antibiotics se vertigo theek ho sakti hai?
Answer: Agar bacterial labyrinthitis ho toh maybe haan, lekin specialist dekhe. Viral labyrinthitis pe antibiotics kaam nahi karti. Diagnosis first, then treatment. Self-treat mat karo; ENT visit karo.
19. Vertigo dangerous hai ya sirf uncomfortable?
Answer: Both! BPPV = uncomfortable (few seconds). Continuous vertigo = can be stroke (dangerous). Plus, bad vertigo se falls aur fractures ho sakte hain. Early evaluation zaruri hai.
20. Peripheral vertigo recovery mein kitna time lagte hai?
Answer: BPPV = weeks. Vestibular neuritis = 2-4 weeks (1st week mein improvement). Labyrinthitis = several weeks. Physical therapy speed up karti hai. Overall prognosis zyada-tar achha hota hai agar HINTS + imaging confirm kare ki peripheral problem hai.
HINDI FAQs (20 Questions)
1. परिधीय और केंद्रीय वर्टिगो में मुख्य अंतर क्या है?
Answer: परिधीय वर्टिगो कान से संबंधित होता है और बिल्कुल सुरक्षित रहता है (जैसे BPPV)। केंद्रीय वर्टिगो मस्तिष्क से संबंधित होता है और जानलेवा होता है, विशेषकर यदि स्ट्रोक हो। परिधीय वर्टिगो में आमतौर पर दोहरी दृष्टि, अस्पष्ट बोली नहीं होती। केंद्रीय में ये सभी लक्षण होते हैं।
2. HINTS परीक्षा MRI से अधिक सटीक है स्ट्रोक पहचानने में?
Answer: हाँ! HINTS परीक्षा 100% सटीक है और 60 सेकंड में परिणाम देती है। शुरुआती MRI (24-48 घंटे में) 50% मामलों में झूठी नकारात्मक आती है क्योंकि स्ट्रोक इतना छोटा और गहरा होता है कि दिखाई नहीं देता। HINTS सिर्फ आँख की गतिविधियों को देखती है और तुरंत बताती है कि स्ट्रोक है या नहीं।
3. असामान्य हेड इम्पल्स परीक्षा का मतलब क्या है?
Answer: असामान्य HIT का मतलब आँखें लक्ष्य से दूर चली जाती हैं और पकड़-अप saccade होता है। इसका मतलब कान में समस्या है, दिमाग ठीक है। यह अच्छी खबर है क्योंकि परिधीय समस्या होती है, स्ट्रोक नहीं।
4. सामान्य हेड इम्पल्स परीक्षा लगातार वर्टिगो के साथ का मतलब?
Answer: यह स्ट्रोक का लाल झंडा है! सामान्य HIT + लगातार घूमना = दिमाग की समस्या, कान नहीं। इसका मतलब ब्रेनस्टेम में स्ट्रोक हो सकता है। तुरंत आपातकालीन कक्ष जाओ।
5. निस्टागमस क्या है और आँख की गतिविधियाँ कौन सी पैटर्न में?
Answer: निस्टागमस = आँखें बार-बार कूद रही हैं। कान की समस्या में: आँखें एक ही दिशा में कूदती हैं। दिमाग की समस्या में: आँखें अलग-अलग दिशाओं में कूदती हैं (दिशा-परिवर्तन) या ऊर्ध्वाधर कूदती हैं। ऊर्ध्वाधर कूदें लगभग 100% स्ट्रोक हो सकती हैं।
6. स्केव विचलन क्या है और यह महत्वपूर्ण क्यों है?
Answer: स्केव विचलन = एक आँख दूसरी से अधिक ऊँची होती है। यह बिल्कुल ब्रेनस्टेम स्ट्रोक का संकेत है। यदि स्केव विचलन + वर्टिगो, तो तुरंत अस्पताल जाओ।
7. डीएस का नियम क्या है?
Answer: 5 चेतावनी संकेत: Diplopia (दोहरी दृष्टि), Dysarthria (अस्पष्ट बोली), Dysphagia (निगलने की समस्या), Dysmetria (समन्वय की कमी), Dysphonia (आवाज में बदलाव)। यदि वर्टिगो + एक भी डी लक्षण = स्ट्रोक की संभावना बहुत अधिक है। आपातकालीन मूल्यांकन चाहिए।
8. शुरुआती MRI झूठी नकारात्मक क्यों हो सकते हैं?
Answer: क्योंकि दिमाग में स्ट्रोक इतना छोटा और गहरा होता है कि पहले 24-48 घंटों में MRI पर नहीं दिखाई देता। जब तक दिखाई देता है, उपचार की खिड़की बंद हो चुकी होती है। इसीलिए HINTS परीक्षा अधिक महत्वपूर्ण है—तुरंत परिणाम देती है।
9. HINTS Plus क्या होता है?
Answer: HINTS Plus = HINTS + श्रवण हानि की जांच। यदि वर्टिगो + अचानक श्रवण हानि एक कान में = आंतरिक श्रवण धमनी में स्ट्रोक हो सकता है। तुरंत इमेजिंग चाहिए।
10. BPPV क्या होता है और इसका वर्टिगो अलग क्यों है?
Answer: BPPV = संक्षिप्त स्थितिजन्य वर्टिगो, सिर्फ कुछ सेकंड, स्थिति-ट्रिगर किया गया। सामान्य HIT होता है। सुरक्षित होता है लेकिन फिर भी ENT को दिखाना चाहिए। लगातार वर्टिगो से बिल्कुल अलग।
11. आपातकालीन कक्ष कब जाओ?
Answer: (1) पहली बार लगातार वर्टिगो >1 घंटा, (2) HINTS निष्कर्ष स्ट्रोक जैसे, (3) वर्टिगो + डी लक्षण, (4) बैठ/खड़े नहीं हो सको, (5) गंभीर सिरदर्द + वर्टिगो, (6) घंटों में प्रगतिशील बदतरी। यदि कोई भी, सीधे ER जाओ।
12. PRIME ENT Center जरूरी नियुक्ति कब लो?
Answer: (1) संक्षिप्त स्थितिजन्य घूमना (BPPV), (2) स्थिर वर्टिगो, सामान्य परीक्षा, (3) ज्ञात BPPV पुनरावृत्ति, (4) वर्टिगो + कान का स्राव/श्रवण हानि, (5) बच्चे में हल्का चक्कर, सामान्य न्यूरो परीक्षा। 24-48 घंटे में नियुक्ति लो।
13. वर्टिगो और चक्कर एक जैसे हैं?
Answer: नहीं! वर्टिगो = घूमने की अनुभूति, विशिष्ट। चक्कर = अस्पष्ट असंतुलन। वर्टिगो = संतुलन प्रणाली की समस्या (गंभीर)। चक्कर = कई कारण (BP, एनीमिया, चिंता)। वर्टिगो अधिक आपातकालीन होता है।
14. बच्चे को स्ट्रोक हो सकता है जो सिर्फ वर्टिगो दे?
Answer: हाँ, लेकिन बिल्कुल दुर्लभ। अधिकांश मामलों में कान की समस्या होती है। लेकिन यदि HINTS निष्कर्ष स्ट्रोक जैसे (सामान्य HIT, दिशा-परिवर्तन निस्टागमस, स्केव), तो इमेजिंग जरूरी है। जोखिम: विच्छेदन, हृदय रोग, थक्का विकार।
15. वेस्टिबुलर सिस्टम क्या होता है?
Answer: कान के अंदर संतुलन केंद्र होता है। सेमीसर्कुलर कैनाल (घूर्णन पहचानते हैं), ओटोलिथ अंग (गुरुत्वाकर्षण पहचानते हैं)। आँखों और शरीर की स्थिति संवेदकों के साथ काम करता है। जब गलती हो जाती है, वर्टिगो आता है।
16. ठंडी हवा से वर्टिगो क्यों ट्रिगर होता है?
Answer: सर्दी से: (1) रक्त वाहिकाएं वेस्टिबुलर नर्व के पास संकीर्ण हो जाती हैं, (2) वायरस सक्रिय हो सकता है (दाद), (3) ठंड का संपर्क वासोकॉन्सट्रिक्शन बनाता है। सर्दियों में वर्टिगो आम होता है।
17. यदि स्ट्रोक संदिग्ध हो लेकिन ER डॉक्टर कान की समस्या कहे तो?
Answer: HINTS परीक्षा विशेष रूप से मांगो। दस्तावेज़ करवाओ: HIT परिणाम, निस्टागमस पैटर्न, स्केव विचलन। यदि चिंताजनक (सामान्य HIT, दिशा-परिवर्तन निस्टागमस), MRI की माँग करो। सामान्य HINTS = सुरक्षित। असामान्य HINTS = आपातकालीन इमेजिंग।
18. एंटीबायोटिक्स से वर्टिगो ठीक हो सकती है?
Answer: यदि जीवाणु labyrinthitis हो तो शायद हाँ, लेकिन विशेषज्ञ देखें। वायरल labyrinthitis पर एंटीबायोटिक्स काम नहीं करती। पहले निदान, फिर उपचार। स्व-उपचार मत करो; ENT विजिट करो।
19. वर्टिगो खतरनाक है या सिर्फ असहज?
Answer: दोनों! BPPV = असहज (कुछ सेकंड)। लगातार वर्टिगो = स्ट्रोक हो सकता है (खतरनाक)। साथ ही, गंभीर वर्टिगो से गिरावट और फ्रैक्चर हो सकते हैं। शीघ्र मूल्यांकन आवश्यक है।
20. परिधीय वर्टिगो की पुनः प्राप्ति में कितना समय लगता है?
Answer: BPPV = हफ्ते। वेस्टिबुलर न्यूराइटिस = 2-4 हफ्ते (1st week में सुधार)। Labyrinthitis = कई हफ्ते। भौतिक चिकित्सा गति बढ़ाती है। समग्र पूर्वानुमान ज्यादातर अच्छा होता है यदि HINTS + इमेजिंग की पुष्टि हो कि परिधीय समस्या है।
