Vestibular Migraine

Overview

Vestibular migraine is a form of migraine in which the main symptom is dizziness or vertigo rather than, or in addition to, headache. The vestibular system, located in the inner ear and brain, helps control balance and the sense of position. In vestibular migraine, this system is affected during attacks, producing a spinning sensation, unsteadiness, or other forms of dizziness.

A distinctive feature is that the vertigo can occur with or without a headache, which can make the condition confusing to recognize. Vestibular migraine is one of the most common causes of recurrent vertigo. While the episodes can be distressing, the condition is not dangerous in itself, and many people improve with trigger management, lifestyle measures, and medication.

Symptoms

Symptoms occur in episodes that can last minutes to hours, and sometimes longer. They may include:

• Vertigo, a sense that you or your surroundings are spinning or moving.
• Dizziness or unsteadiness and a feeling of imbalance.
• Sensitivity to motion, with symptoms triggered or worsened by head movement or busy visual scenes.
• Sensitivity to light and sound, common in migraine.
• Nausea or vomiting.
• Headache, which may or may not be present during an attack.
• Visual aura or other migraine features in some people.

Between episodes, many people feel well, although some have lingering imbalance or motion sensitivity.

Causes

The exact cause of vestibular migraine is not fully understood, but it is closely related to the same brain mechanisms involved in other migraines. Contributing factors include:

• Changes in brain activity and nerve signaling that affect both pain pathways and the balance system.
• A personal or family history of migraine, suggesting a genetic tendency.
• Triggers that can set off an episode, similar to other migraine triggers.

Common triggers include stress, lack of sleep or changes in sleep, certain foods and drinks, caffeine, dehydration, hormonal changes, bright or flickering lights, and strong smells. Identifying personal triggers is an important part of managing the condition.

Risk Factors

Factors that increase the likelihood of vestibular migraine include:

• A history of migraine, especially migraine with aura.
• A family history of migraine or of vertigo with migraine.
• Sex, as migraine in general is more common in women.
• A history of motion sickness, which is often reported by people with vestibular migraine.

Diagnosis

There is no single test for vestibular migraine, so diagnosis is based on the pattern of symptoms and the exclusion of other causes of vertigo. Evaluation typically includes:

• A detailed history of the episodes, including their duration, triggers, associated migraine features, and any personal or family history of migraine.
• A physical and neurological examination, including tests of balance, eye movements, and hearing.
• Tests to rule out other conditions, such as inner ear disorders, which may include hearing tests, balance testing, and sometimes imaging like an MRI.

Distinguishing vestibular migraine from conditions such as Meniere disease, benign positional vertigo, and inner ear inflammation is a key part of the assessment.

Treatment

Treatment combines managing acute attacks with preventing future episodes. Common approaches include:

• Identifying and avoiding triggers, often with the help of a symptom diary.
• Lifestyle measures: Regular sleep, staying hydrated, eating regular meals, limiting caffeine and alcohol, and managing stress.
• Acute medications to relieve symptoms during an attack, which may include anti-nausea medicines and migraine treatments.
• Preventive medications for people with frequent or severe episodes, similar to those used to prevent other migraines.
• Vestibular rehabilitation, a type of physical therapy that helps the brain adapt and improves balance and motion tolerance.

A combination of these strategies, tailored to the individual, usually provides the best results.

Prevention

Reducing the frequency of attacks often relies on consistent habits that lower migraine triggers:

• Keep a regular sleep schedule and avoid sleep deprivation.
• Stay hydrated and avoid skipping meals.
• Identify and limit personal food and drink triggers.
• Manage stress with techniques that work for you.
• Limit caffeine and alcohol if they are triggers.
• Take any prescribed preventive medication as directed.

When to See a Doctor

See a healthcare provider if you have recurrent episodes of vertigo or dizziness, especially if you have a history of migraine, so the cause can be identified and treatment started.

Seek urgent or emergency care if dizziness or vertigo is sudden and severe or is accompanied by warning signs of a possible stroke or other serious problem, such as: a sudden severe headache unlike any before, weakness or numbness in the face, arm, or leg, difficulty speaking or understanding speech, double vision or vision loss, trouble walking, severe imbalance, or fainting. These symptoms require immediate evaluation to rule out a more serious condition.
