Vestibular Migraine: Symptoms, Types, Causes and Treatment

Vestibular migraine is a fascinating yet often misunderstood condition that sits at the crossroads of neurology and otology. Unlike classic migraine, which is primarily associated with headache, vestibular migraine is characterized by episodes of dizziness, vertigo, and balance disturbances, sometimes even in the absence of headache. This condition can significantly impact quality of life, yet remains underdiagnosed and frequently confused with other vestibular disorders. In this comprehensive article, we explore the symptoms, types, underlying causes, and evidence-based treatment approaches for vestibular migraine, synthesizing the latest clinical research.

Symptoms of Vestibular Migraine

Understanding the symptoms of vestibular migraine is crucial for both patients and healthcare providers, as its presentation often overlaps with other vestibular and migraine disorders. Vestibular migraine is defined by episodic vestibular symptoms, which are frequently accompanied by migraine features such as headache, photophobia, or aura. However, in many cases, vestibular symptoms can occur even in the absence of head pain, making diagnosis particularly challenging.

Symptom	Description	Duration/Frequency	Source(s)
Vertigo	Spinning or swaying sensation	Seconds to 72 hours; recurrent	1 2 3 5 6 9
Dizziness	Feeling off-balance, ground slipping	Recurrent, often brief or chronic	5 9
Nausea	Queasiness, urge to vomit	During vestibular episodes	1 4 9
Photophobia	Sensitivity to light	Often with vestibular symptoms	2 9
Phonophobia	Sensitivity to sound	Often with vestibular symptoms	9
Headache	Migraine-type, often severe	May or may not coincide with vertigo	2 4 8 9
Motion Sickness	Discomfort with movement	History or during episodes	4 5
Visual Vertigo	Dizziness from visual stimuli	Triggered by busy environments	5 12
Tinnitus	Ringing in ears	Sometimes present	4
Aural Fullness	Sensation of ear pressure	Sometimes present	4

A Closer Look at Vestibular Migraine Symptoms

Vestibular migraine symptoms are diverse, but some patterns emerge:

Vertigo and Dizziness

• Vertigo is the most prominent symptom—a sensation of spinning, swaying, or being on a rocking boat. Some patients describe feeling as if the ground is slipping or that they are stepping onto empty space 5.
• Dizziness may be chronic and recurrent, often triggered by head or body movements, visual stimuli, or busy environments 5.

Duration and Severity

• Attacks typically last from seconds to several hours, and can extend up to 72 hours in rare cases. The duration and frequency of episodes can vary widely, with some patients having multiple brief attacks per day 1 2 5 6.
• The intensity is usually moderate to severe, and symptoms often interfere with daily activities.

Migraine Features

• While headaches may be absent during vestibular attacks, other migraine features—including photophobia (light sensitivity), phonophobia (sound sensitivity), visual aura, or nausea—are common 2 9.
• Some patients experience both headache and vestibular symptoms concurrently, while others may have one without the other 8.

Additional Symptoms

• Nausea and vomiting occur frequently during acute episodes 1 4.
• Auditory symptoms such as tinnitus (ringing in the ears) and aural fullness can be present, especially in patients with overlapping Meniere’s disease 4.
• Motion sickness history is common, affecting over half of patients 4 5.

Impact on Daily Life

• Many patients report difficulty in visually stimulating environments, such as supermarkets or crowded areas 5 12.
• Chronic dizziness and balance issues can lead to anxiety, reduced confidence, and avoidance behaviors.

Types of Vestibular Migraine

Vestibular migraine is not a one-size-fits-all disorder. There are several subtypes, each with distinct diagnostic criteria and clinical features. Recognizing these types helps tailor diagnosis and management, particularly in children and in cases with overlapping vestibular conditions.

Type	Criteria/Features	Age Group	Source(s)
Definite Vestibular Migraine	≥5 moderate/severe episodes, 5 min–72 hr, history of migraine, ≥50% with migraine features	All ages	1 3 7
Probable Vestibular Migraine	Fewer episodes or missing migraine features	All ages	1 7
Vestibular Migraine of Childhood (VMC)	≥5 episodes, migraine history, ≥50% with migraine features	<18 years	7
Probable VMC	≥3 episodes, with only migraine history or migraine features	<18 years	7
Recurrent Vertigo of Childhood (RVC)	≥3 episodes, vestibular symptoms, no migraine history/features	<18 years	7
VM with Meniere’s/BPPV	Vestibular migraine with coexisting Meniere’s or BPPV	All ages	4

Table 2: Types and Subtypes of Vestibular Migraine

Exploring the Types of Vestibular Migraine

Definite and Probable Vestibular Migraine

• Definite Vestibular Migraine requires at least five episodes of moderate to severe vestibular symptoms lasting 5 minutes to 72 hours, a current or past history of migraine, and migraine features (like headache, photophobia, or aura) during at least 50% of vestibular episodes 1 3.
• Probable Vestibular Migraine is diagnosed when some—but not all—criteria are met (e.g., fewer episodes or missing migraine features) 1.

Childhood Variants

• Vestibular Migraine of Childhood (VMC) and Probable VMC are pediatric forms, with similar episode criteria but occurring before age 18 7.
• Recurrent Vertigo of Childhood (RVC) is diagnosed when children have recurrent vestibular symptoms without migraine features 7.

Overlapping Conditions

• Vestibular migraine may coexist with other vestibular disorders such as Meniere’s disease or benign paroxysmal positional vertigo (BPPV). These cases often present additional symptoms like tinnitus, aural fullness, or hearing loss 4.

Temporal Patterns

• The onset of vestibular and migraine symptoms can vary—some patients develop migraine first, others vertigo, and some experience both concurrently. These patterns may influence symptom frequency and severity 8.

Causes of Vestibular Migraine

The precise cause of vestibular migraine remains elusive, but research has uncovered several contributing factors, including genetics, neurovascular mechanisms, and abnormal brain network interactions. Understanding these causes sheds light on why the condition is so complex and variable.

Cause	Mechanism/Description	Notes/Implications	Source(s)
Genetic factors	Family history common; heritable susceptibility	Early onset, strong family links	4 10
Trigeminal-vestibular interactions	Migraine pathways affect vestibular nuclei	Inflammation, sensory overlap	2 10
Brain network dysfunction	Dysregulation in sensory integration areas	Abnormal processing of vestibular & pain signals	10 12
Sensitization of central vestibular pathways	Lowered motion perception thresholds	Heightened motion/visual sensitivity	11 12
Hormonal/environmental triggers	Stress, sleep, diet, sensory overload	Trigger attacks	2 9

What Drives Vestibular Migraine?

Genetics and Susceptibility

• Vestibular migraine often runs in families, with up to 72% of patients reporting a family history of migraine 4.
• Genetic, epigenetic, and environmental factors likely interact to create a predisposition 10.

Neurovascular and Sensory Pathways

• Migraine involves activation of the trigeminal nerve system, which is closely connected to the vestibular (balance) system 2 10.
• Neurogenic inflammation, triggered by the trigeminal-vestibulocochlear reflex, may cause inner ear disturbances and increase vestibular sensitivity 10.

Central Sensitization and Brain Network Dysfunction

• Functional imaging and clinical studies reveal abnormal processing in brain regions that integrate vestibular and pain information, including the thalamus, cortex, and brainstem 10 12.
• Patients with vestibular migraine have lower thresholds for motion perception, particularly with combined head movements, suggesting central sensitization of vestibular pathways 11.

Trigger Factors

• Common triggers include stress, hormonal changes, sleep disturbances, certain foods, and sensory overload (visual or auditory) 2 9.
• In many patients, attacks can be precipitated by visual motion or head movement, reflecting abnormal integration of sensory cues 5 12.

Treatment of Vestibular Migraine

Treatment of vestibular migraine aims to reduce the frequency and severity of episodes, improve quality of life, and address coexisting migraine or vestibular symptoms. Management is highly individualized, combining lifestyle modifications, acute symptom relief, and preventive (prophylactic) therapies.

Treatment	Purpose/Mechanism	Effectiveness/Notes	Source(s)
Acute medications	Antiemetics, antivertiginous drugs	For severe attacks; temporary relief	2 14
Migraine prophylaxis	β-blockers, antidepressants, anticonvulsants	Reduce frequency/severity; mainstay	13 14
CGRP monoclonal antibodies	Target migraine pathways	New option; high efficacy	16 17
Vestibular suppressants	Symptomatic relief	Often limited benefit	5
Lifestyle modifications	Avoid triggers, sleep, diet	Essential adjunct	2 14
Vestibular rehabilitation	Physical therapy for balance	For chronic or complicated cases	14

Strategies for Managing Vestibular Migraine

Acute Attack Management

• Antiemetics (like ondansetron) and general antivertiginous drugs can help relieve severe nausea and vertigo during attacks, but their effectiveness is often limited to symptom control 2 14.
• Specific migraine drugs (such as triptans) are less effective for vestibular symptoms compared to classic migraine pain 14.

Preventive (Prophylactic) Therapies

• The cornerstone of long-term management is migraine prophylaxis. Medications used include:
  • Beta-blockers (propranolol, metoprolol): Preferred for patients with hypertension (but not asthma) 13 14.
  • Anticonvulsants (topiramate, valproic acid, lamotrigine): Topiramate is favored in overweight patients, lamotrigine for frequent vertigo 13 14.
  • Calcium channel blockers (flunarizine, verapamil): Useful especially for comorbid migraine features 13 14.
  • Antidepressants (amitriptyline, nortriptyline): Good choice when anxiety or depression coexist 13 14.
• Studies show that 77–81% of patients improve with prophylactic medications, with no single drug being clearly superior 6 13 14.

Newer Treatments: CGRP Monoclonal Antibodies

• CGRP monoclonal antibodies (erenumab, fremanezumab, galcanezumab) are a breakthrough for migraine prevention and are now being used for vestibular migraine 16 17.
• Clinical studies show high efficacy: up to 90% of patients experience at least a 50% reduction in vertigo frequency, and most also have reduced headache burden 17.

Non-Pharmacological Approaches

• Lifestyle modifications are crucial: avoiding known triggers, maintaining regular sleep, staying hydrated, and eating regular meals 2 14.
• Vestibular rehabilitation therapy (balance exercises) is recommended for patients with persistent dizziness or loss of confidence in their balance 14.
• Psychological support and management of anxiety/depression may be beneficial in some cases.

Special Considerations

• Medication choice should be tailored to the patient's comorbidities, side effect profiles, and personal preferences 14.
• In children, diagnostic criteria and treatment must be adapted for age and developmental stage 7.
• Overlapping vestibular conditions (like Meniere’s or BPPV) may require additional therapy 4.

Conclusion

Vestibular migraine is a common but frequently unrecognized cause of episodic dizziness and vertigo, with a complex interplay of migraine and vestibular symptoms. Understanding its diverse presentations, subtypes, underlying pathophysiology, and evidence-based treatment options is key for both effective patient care and improved quality of life.

Key Takeaways:

• Vestibular migraine presents with recurrent vertigo, dizziness, and often—but not always—migraine features like headache or photophobia 1 2 9.
• Types include definite/probable vestibular migraine, childhood variants, and combinations with other vestibular disorders 1 4 7.
• Causes are multifactorial, involving genetics, neurovascular mechanisms, central sensitization, and environmental triggers 4 10 11.
• Treatment combines acute symptom relief, migraine prophylaxis (including new CGRP monoclonal antibodies), lifestyle changes, and sometimes vestibular rehabilitation 13 14 16 17.
• Early recognition and tailored management can dramatically improve outcomes for those living with this challenging disorder.
