Wallenberg Syndrome (Lateral Medullary Syndrome)

Wallenberg syndrome happens when the side (lateral) part of the medulla—a small but vital area at the bottom of the brainstem—loses its blood supply, most often from a blockage in the vertebral artery or posterior inferior cerebellar artery (PICA). Because the medulla controls swallowing, balance, sensation, eye movements, breathing patterns, hiccup reflexes, and voice, the symptoms can look “mixed”: sudden dizziness, spinning, unsteady walking, double vision or jerky eye movements, hoarseness, loss of sensation on one side of the face with loss of pain/temperature on the other side of the body, droopy eyelid and small pupil (Horner syndrome), choking on food or liquids, intractable hiccups, and severe imbalance. Doctors diagnose it with a focused neurological exam and MRI of the brainstem. Treatment follows stroke best practices plus targeted rehab for swallowing, balance, vision, and voice. NCBICleveland Clinic

Wallenberg syndrome—also called lateral medullary syndrome—is a stroke that damages the side (lateral) part of the medulla, the lowest part of the brainstem. This area houses balance centers, swallowing and voice centers, pain-and-temperature pathways, coordination circuits, and sympathetic fibers. When blood flow is blocked—most often in a branch called the posterior inferior cerebellar artery (PICA) or in the vertebral artery—these functions are disrupted. People can suddenly develop vertigo, imbalance, trouble swallowing, hoarse voice, intractable hiccups, loss of pain/temperature on one side of the face and the other side of the body, clumsy limbs, and Horner syndrome (small pupil and droopy eyelid on the same side as the stroke). NCBIEyeWiki

The spinal trigeminal nucleus (face pain/temperature) sits on the same side of the medulla as the stroke, while the spinothalamic tract (body pain/temperature) has already crossed to the opposite side. Damage therefore produces ipsilateral facial loss and contralateral body loss. Nearby, the inferior cerebellar peduncle causes limb ataxia, vestibular nuclei cause vertigo and nystagmus, the nucleus ambiguus (cranial nerves IX and X) causes dysphagia and dysphonia, and descending sympathetic fibers cause Horner syndrome.

Types

1. Typical PICA-territory lateral medullary infarct
   The most common pattern. Blood flow in the PICA is blocked; symptoms include vertigo, ataxia, facial pain/temperature loss on the same side, body pain/temperature loss on the other side, hoarse voice, and swallowing difficulty. NCBI

2. Vertebral-artery–related lateral medullary infarct
   A clot or a vertebral artery dissection (a tear in the inner vessel wall, sometimes after neck rotation/trauma) blocks flow before the PICA branch, producing the same lateral medullary picture. Often occurs in younger patients. NCBI

3. Rostral (upper) vs. caudal (lower) lateral medullary infarct
   Small strokes can affect a higher or lower slice of the medulla. Upper lesions more often produce prominent vertigo and nystagmus; lower lesions may emphasize pharyngeal weakness and hiccups. MRI studies map these locations. strokejournal.org

4. Partial (incomplete) vs. extensive (complete) lateral medullary syndrome
   When only a portion of the lateral medulla is involved, people may have only some features (for example, mainly dizziness and ataxia). Larger lesions produce the full classic triad of vestibular, sensory, and bulbar (swallow/voice) signs. NCBI

5. Opalski variant
   A rare variant where the stroke extends below the pyramidal crossing, causing ipsilateral weakness (same side arm/leg weakness) along with the usual lateral medullary features.

6. Babinski–Nageotte pattern
   Mixed features of lateral medullary damage plus contralateral weakness when lesions straddle neighboring tracts in the medulla. (These eponyms simply reflect how far the infarct edges extend.)

These “types” describe where the stroke sits in the medulla and how much tissue it involves. The blood-vessel problem is the root cause in all of them.

Causes

In every cause below, the core problem is reduced blood flow to the lateral medulla, most often via the PICA or vertebral artery:

1. Atherosclerotic plaque in the vertebral or PICA artery making a local clot (thrombosis).

2. Embolus from the heart (for example from atrial fibrillation) lodging in PICA/vertebral branches.

3. Embolus from the neck arteries, where a plaque releases debris that travels upward.

4. Vertebral artery dissection after neck rotation, sudden extension, minor trauma, or spontaneous tear.

5. Small-vessel disease of penetrating medullary arteries (linked to hypertension and diabetes).

6. Hypercoagulable states (e.g., cancer-related clotting, inherited thrombophilia) causing sudden arterial blockage.

7. Antiphospholipid antibody syndrome forming artery clots.

8. Vasculitis (e.g., giant cell arteritis, Takayasu, ANCA-vasculitis) inflaming and narrowing arteries.

9. Endocarditis with septic emboli traveling to PICA/vertebral territory.

10. Patent foramen ovale or other shunts allowing a venous clot to pass to the arteries (paradoxical embolus).

11. Neck surgery or catheter procedures injuring the vertebral artery.

12. Cervical manipulation/trauma producing a vertebral intimal tear and clot.

13. Radiation-induced arteriopathy of cervical vessels, years after head/neck radiotherapy.

14. Arterial fibromuscular dysplasia causing stenosis/tortuosity in the vertebral artery.

15. Vertebrobasilar dolichoectasia (enlarged, tortuous arteries) predisposing to sluggish flow and clot.

16. Cocaine/amphetamine-related vasospasm and thrombosis in posterior circulation.

17. Severe dehydration and hypotension on top of tight stenosis, tipping the balance into ischemia.

18. Vertebral artery aneurysm thrombosis occluding distal flow.

19. Sickle cell disease or other hemoglobinopathies with vascular occlusion.

20. Rare PICA anomalies or hypoplasia that make the region vulnerable when flow drops.

In large series, vertebral-artery/PICA occlusion or dissection dominates. Most patients are older with typical vascular risk factors, but dissection is a key cause in younger adults. NCBI

Common symptoms

1. Sudden vertigo (spinning or tilting sensation).

2. Nausea and vomiting, often severe at onset.

3. Gait imbalance and truncal ataxia—leaning or falling toward the stroke side.

4. Limb ataxia—clumsy arm/leg on the same side as the stroke.

5. Nystagmus—jerky eye movements; vision feels jumpy.

6. Dysphagia—trouble swallowing; choking; food/liquid going “the wrong way.”

7. Dysphonia/hoarseness—breathy, weak, or nasal-sounding voice.

8. Intractable hiccups (singultus), sometimes for days.

9. Reduced pain and temperature on the face on the same side as the stroke.

10. Reduced pain and temperature on the body/limbs on the opposite side.

11. Horner syndrome on the stroke side—small pupil, droopy eyelid, decreased facial sweating.

12. Decreased gag and cough reflex, nasal regurgitation of fluids, and uvula deviation.

13. Oscillopsia—world bounces with head movement because the vestibular system is impaired.

14. Hemisensory numbness/tingling due to spinothalamic involvement.

15. Headache or neck pain, especially with vertebral artery dissection.
    These features reflect damage to the vestibular nuclei, inferior cerebellar peduncle, nucleus ambiguus, spinal trigeminal nucleus, spinothalamic tract, and descending sympathetic fibers in the lateral medulla. NCBIPMC

Diagnostic tests

A) Physical exam (bedside neurologic examination)

1. Targeted posterior-circulation stroke screen (NIHSS-informed)
   Clinician checks mental status, speech, eyes, face, arms/legs, and sensation. In posterior strokes, the NIHSS can under-score deficits, so examiners emphasize gaze, nystagmus, ataxia, and bulbar signs.

2. Cranial nerves IX and X exam (palate and voice)
   Look for palate asymmetry, uvula deviation away from the lesion, nasal speech, and breathy/hoarse voice, signaling nucleus ambiguus involvement.

3. Gag and cough reflex check
   Blunted gag and voluntary cough point to bulbar weakness and raise aspiration risk.

4. Face and body pain/temperature mapping
   Light pinprick/cold testing shows loss on the face ipsilateral to the lesion and loss on the body contralateral—a hallmark of lateral medullary damage.

5. Cerebellar coordination tests
   Finger–nose–finger and heel–knee–shin reveal limb ataxia on the stroke side; rapid alternating movements are slow and erratic.

6. Ocular motor exam
   Observe spontaneous nystagmus, gaze-evoked nystagmus, and smooth pursuit failure; note head tilt and skew deviation that suggest a central lesion. NCBI

B) Manual tests (simple bedside maneuvers)

7. Head-Impulse test (part of HINTS)
   A normal head-impulse in a patient with continuous vertigo suggests stroke (a peripheral ear problem gives an abnormal catch-up saccade). HINTS can be more sensitive than early MRI in the first 24–48 hours for detecting posterior strokes. PubMed+1

8. Test of Skew (alternate cover test)
   Vertical realignment of the eyes when alternately covered implies central otolith pathway damage—supporting a brainstem cause. (It’s the “S” in HINTS.) PubMed

9. Bedside swallow screen (e.g., 3-ounce water test)
   Quick check for coughing, wet voice, or aspiration risk. A failed screen triggers instrumental assessment (FEES or VFSS) and NPO precautions to prevent pneumonia. AHAjournals

10. Romberg, tandem gait, and stance testing
    Patients often fall toward the lesion side; severe truncal ataxia is common in lateral medullary infarct. NCBI

C) Lab and pathological tests (to find the cause and risks)

11. Complete blood count (CBC)
    Looks for polycythemia, anemia, infection, or platelet problems that can influence clotting risk.

12. Fasting glucose and HbA1c; metabolic panel
    Detects diabetes and metabolic triggers of vascular disease.

13. Lipid profile
    Atherosclerosis risk estimate to guide secondary prevention.

14. Coagulation and hypercoagulable panel
    PT/INR, aPTT, antiphospholipid antibodies, and selected thrombophilia tests (guided by age/history) for unusual clots; add ESR/CRP when vasculitis is suspected.

D) Electrodiagnostic tests

15. Brainstem Auditory Evoked Potentials (BAEPs)
    Measures conduction through lower brainstem pathways. Abnormal latencies can support brainstem involvement when MRI is initially equivocal. PubMed

16. Laryngeal electromyography (EMG)
    If vocal fold paralysis is suspected, EMG helps confirm nucleus ambiguus/vagus dysfunction and guides voice/swallow rehabilitation.

E) Imaging and instrumental tests (confirm the diagnosis and the vessel problem)

17. MRI brain with diffusion-weighted imaging (DWI) and FLAIR
    Best test to confirm the stroke. DWI shows bright signal in the lateral medulla; note that very early scans can be negative, so repeat imaging may be needed when suspicion remains high. PMC

18. MRA or CT angiography (head and neck)
    Shows vertebral/PICA occlusion or vertebral artery dissection and helps plan treatment. NCBI

19. Fiberoptic Endoscopic Evaluation of Swallowing (FEES)
    A bedside, radiation-free test where a tiny camera views the larynx/pharynx during swallowing. Increasingly used first-line after a failed swallow screen to grade aspiration risk and tailor diet/therapy. PubMedBioMed Central

20. Videofluoroscopic Swallow Study (VFSS, modified barium swallow)
    X-ray video of swallowing that shows aspiration, penetration, and physiologic deficits (e.g., poor pharyngeal constriction). Early VFSS in stroke guides safe feeding plans. AHAjournalsPMC

Dietary “molecular” supplements

(Use only with your clinician; these do not replace prescribed therapy.)

1. Omega-3 (EPA/DHA 1–2 g/day). Supports anti-inflammatory lipid profile; membrane fluidity in neurons.

2. Vitamin D3 (1,000–2,000 IU/day or per level). Immune modulation, bone and muscle; possible vascular benefits.

3. B-complex with B12 (e.g., methyl-B12 500–1,000 mcg/day if deficient). Lowers homocysteine; supports nerve health.

4. Magnesium (200–400 mg/day). Nerve/muscle function; may help cramps/sleep.

5. CoQ10 (100–200 mg/day). Mitochondrial energy cofactor; antioxidant.

6. Curcumin (standardized extract ~500–1,000 mg/day with piperine). Anti-inflammatory signaling (NF-κB).

7. Resveratrol (100–250 mg/day). Antioxidant; endothelial nitric-oxide signaling.

8. Citicoline/CDP-choline (500–1,000 mg/day). Membrane phospholipid precursor; studied as neuro-support (mixed evidence).

9. Acetyl-L-carnitine (500–1,000 mg/day). Mitochondrial fatty-acid transport; cognitive/neuropathic support.

10. Alpha-lipoic acid (300–600 mg/day). Antioxidant; glucose and neuropathic symptom support.
    Lifestyle patterns (e.g., Mediterranean-style diet) carry stronger evidence for stroke prevention than any single supplement. BMJPMCPubMed

Regenerative / stem-cell” drugs

Important: There are no approved stem-cell drugs for Wallenberg syndrome recovery. These are investigational or supportive concepts—not standard care. Do not pursue outside regulated clinical trials.

1. Mesenchymal stem cell (MSC) infusions (trial-only).
   Dose: Trial-defined. Function: Attempt to promote repair. Mechanism: Paracrine trophic/anti-inflammatory effects; results remain inconclusive. Use only in IRB-approved trials.

2. Umbilical-cord-derived cells / exosomes (trial-only).
   Function/Mechanism: Experimental neurotrophic signaling; no approved clinical use.

3. Granulocyte colony-stimulating factor, G-CSF (trial-only).
   Function: Mobilizes progenitors; explored in stroke with mixed outcomes; bleeding risk if combined with antithrombotics. Research-only.

4. Intrathecal botulinum approaches (not stem-cell, included for clarity): Not used for brainstem stroke recovery; botulinum is used locally for cricopharyngeal hypertonicity—not systemic regeneration. MDPI

5. Transcranial/neuromuscular electrical stimulation as a “regenerative adjunct.”
   Function: Activity-dependent plasticity; adjunct to therapy, not a drug. www.heart.org

6. Vaccines & infection prevention (influenza/COVID) as “immune support.”
   Function: Prevent infections that derail rehab and raise stroke risk; part of best-practice secondary prevention. Mechanism: Reduces systemic inflammation and complications. AHAjournals

Procedures & surgeries

1. Endovascular therapy (mechanical thrombectomy) for posterior-circulation large-vessel occlusion (selected cases).
   Why: If a basilar or vertebral artery is acutely blocked and criteria are met, EVT can improve outcomes. This is not for small PICA branch occlusions but can apply when a large artery is involved. j-stroke.orgneurointervention.orgAHAjournals

2. Percutaneous endoscopic gastrostomy (PEG).
   Why: If swallowing is unsafe for >2–4 weeks despite nasogastric feeding, a PEG provides durable nutrition and safe medication delivery. PMC

3. Cricopharyngeal interventions for UES dysfunction (Botox injection or cricopharyngeal myotomy).
   Why: In selected patients with proven UES non-relaxation after medullary stroke, targeted Botox can temporarily reduce UES spasm; persistent, well-documented cases may need surgical myotomy. MDPIPubMedWiley Online Library

4. Suboccipital decompressive craniectomy (± ventriculostomy) for malignant cerebellar swelling.
   Why: If a large cerebellar infarct causes brainstem compression or obstructive hydrocephalus with deterioration, urgent decompression saves life and function. www.heart.orgAHAjournals

5. Endovascular stenting for symptomatic vertebral artery atherosclerotic stenosis (highly selected).
   Why: Considered when there is recurrent ischemia despite best medical therapy; evidence is mixed, and decisions are individualized in expert centers. ESVSPMC

FAQs

1) Is Wallenberg syndrome always a stroke?
Usually yes—it’s most often from an ischemic stroke in the lateral medulla due to vertebral or PICA blockage. Rarely, similar symptoms can follow inflammation or demyelination. NCBI

2) Why are swallowing problems so common?
The medulla coordinates the precise, rapid sequence of swallowing. Damage disrupts this timing, causing choking risk that needs SLP-guided rehab. ebrsr.com

3) Do symptoms improve?
Many people improve over weeks to months with targeted therapy, though some may have lasting imbalance or sensory changes. Early, intensive rehab helps. Physiopedia

4) Can I get mechanical thrombectomy?
Only if you meet criteria for a posterior-circulation large-vessel occlusion (e.g., basilar artery). Small branch PICA strokes usually aren’t thrombectomy targets. j-stroke.org

5) I can’t swallow safely—how long before a PEG is considered?
Guidelines generally try nasogastric feeding for 2–4 weeks first; PEG is considered if swallowing remains unsafe. PMC

6) Why do I have nonstop hiccups?
The hiccup reflex arc runs through the medulla. Irritation from the stroke can trigger persistent hiccups; baclofen or gabapentin may help. PMCMedscape eMedicine

7) Is double vision permanent?
It often improves as the brain adapts. Eye exercises, prism lenses, or temporary occlusion may be used short-term. Physiopedia

8) Are stem-cell treatments available?
Not as approved care. Stem-cell and exosome therapies are trial-only; benefits remain unproven. Avoid clinics making unverified claims. (See section above.)

9) Should I be on two antiplatelet drugs long-term?
No. Dual antiplatelet therapy (DAPT) is short-term for specific minor stroke/TIA scenarios; long-term DAPT is not recommended for most patients. AHAjournals

10) If my stroke was from a vertebral artery dissection, is anticoagulation better than antiplatelet?
Recent data suggest anticoagulation may reduce recurrent ischemic events vs antiplatelet in cervical artery dissection, but the choice is individualized. AHAjournals+1

11) Can therapy really change swallowing?
Yes—exercises like Mendelsohn, effortful swallow, CTAR/Shaker show improvements in selected patients when done consistently under SLP guidance. PMCwww.heart.org

12) What if I keep aspirating despite therapy?
Targeted procedures (e.g., cricopharyngeal Botox or myotomy) may help when a proven UES-opening problem is the main barrier. MDPIPubMed

13) Why might a neurosurgeon talk about decompression for a “Wallenberg-like” case?
If a large cerebellar infarct next to the medulla is swelling and compressing the brainstem, suboccipital decompression can be lifesaving. www.heart.org

14) What lifestyle changes matter most to prevent another stroke?
Life’s Essential 8: eat better, be active, no nicotine, healthy sleep, manage weight, control cholesterol, glucose, and blood pressure. AHAjournals

15) Do supplements replace medicines?
No—supplements are adjuncts. The strongest prevention evidence comes from medications + lifestyle (BP, statin, antiplatelet/anticoagulation when indicated, Mediterranean-style eating, exercise, no smoking). professional.heart.orgBMJ
