Vestibular Migraine: Causes, Symptoms & How to Speak to an Online Doctor

Vestibular migraine, also known as migraine-associated vertigo, is a leading cause of episodic vertigo in the UK. While a typical migraine is characterised by a throbbing headache, a vestibular migraine primarily affects your balance and spatial orientation. According to NHS and NICE guidance, it is one of the most common reasons patients present with sudden dizziness.

Instead of (or in addition to) pain, the brain's processing of sensory information is disrupted. This can result in a feeling that the world is spinning, even when you are perfectly still. It can be a debilitating condition that interferes with work, driving, and daily life, but with the right management plan, symptoms can be significantly reduced.

The symptoms of vestibular migraine can vary significantly between individuals. Some patients experience symptoms for a few seconds, while others may feel 'off-balance' for several days. Key symptoms frequently reported by UK patients include:

• Vertigo: A sensation of spinning, swaying, or tilting.
• Imbalance: Feeling unsteady on your feet or as if you are being pushed to one side.
• Motion sensitivity: Feeling nauseated when moving your head, looking at moving objects, or travelling in a car.
• Visual disturbances: Sensitivity to bright lights, computer screens, or busy environments like supermarkets.
• Aural symptoms: A feeling of pressure in the ear (aural fullness) or muffled hearing, which can sometimes be confused with Meniere’s disease.

Crucially, many UK patients find that they do not have a headache during every episode. The 'vestibular' elements can occur before, during, or completely independently of any head pain.

Triggers and Risk Factors

The exact cause of vestibular migraine is not fully understood, but it is believed to involve abnormal electrical activity in the brain that affects the vestibular (balance) system. Researchers suggest that genetics play a significant role, as many sufferers have a family history of migraines.

Triggers often mirror those of classic migraines. In the UK, common triggers identified by patients include:

• Dietary factors: Caffeine, alcohol (particularly red wine), aged cheeses, and MSG.
• Stress and Anxiety: High levels of cortisol can lower the threshold for an attack.
• Sleep disturbances: Lack of sleep or irregular sleep patterns.
• Hormonal changes: Many women notice a link between their menstrual cycle or menopause and the frequency of attacks.
• Environmental factors: Weather changes, flickering lights, or strong odours.

Diagnosing vestibular migraine can be challenging because there is no single 'test' for it. Instead, UK doctors use the International Classification of Headache Disorders (ICHD) criteria, which are supported by NICE guidelines. A diagnosis is typically made if you have a history of migraines and at least five episodes of vestibular symptoms that last between 5 minutes and 72 hours.

Your GP will likely want to rule out other causes of dizziness, such as Benign Paroxysmal Positional Vertigo (BPPV), ear infections, or labyrinthitis. They may ask you to keep a 'symptom diary' for several weeks, noting down what you were doing, what you ate, and how long the dizziness lasted. This helps the clinician identify patterns that point toward a vestibular migraine diagnosis.

Lifestyle adjustments are the cornerstone of managing vestibular migraine in the UK. By stabilising your routine, you can prevent the nervous system from becoming overstimulated. The 'SEEDS' approach is often recommended by specialists:

• S – Sleep: Maintain a consistent sleep schedule, even on weekends.
• E – Eating: Avoid skipping meals, as low blood sugar can trigger an attack.
• E – Exercise: Regular, low-impact exercise can improve cardiovascular health and reduce stress.
• D – Drinking: Stay well-hydrated and limit caffeine/alcohol.
• S – Stress Management: Consider mindfulness, yoga, or Cognitive Behavioural Therapy (CBT) to manage anxiety levels.

Additionally, Vestibular Rehabilitation Therapy (VRT) is a UK-recognised treatment. This involves specific exercises designed to retrain the brain to compensate for balance signals, helping you feel more stable during daily activities.

If you are experiencing recurrent episodes of dizziness or vertigo that are impacting your life, it is important to seek medical advice. You do not have to wait weeks for an appointment; you can speak to a GP online to discuss your symptoms and explore potential treatment pathways.

An online consultation is particularly useful for:

• Discussing a history of migraines and how they relate to your current dizziness.
• Reviewing your current medications to see if they are effective or if you need a referral to an ENT specialist or neurologist.
• Getting advice on triggers and lifestyle modifications tailored to your routine.
• Obtaining private sick notes if your symptoms are preventing you from attending work.

A UK-based online doctor can review your clinical history and, if appropriate, suggest preventative medications such as propranolol, amitriptyline, or topiramate, which are commonly prescribed under NICE guidelines for migraine prevention.
