What is Migraine Associated Vertigo
Migraine Associated Vertigo (MAV) is now recognised as a separate diagnosis to the classic migraine. The same physiological process is thought to happen but this not only affect the pain sensors in the brain but also the vestibular system due to its close proximity.
Migraines cause a dilation (expansion) of blood vessels. This leads to change in blood flow to the vestibular organs and nerves thus a change in its ability to function correctly. MAV has also been shown to change the neural firing in the brain which disorganises normal input telling us how to balance and not become dizzy. These two faults lead to incorrect input and processing of the balance system which lead to vertigo symptoms.
What are the symptoms of Migraine Associated Vertigo
The symptoms of MAV can be varied and unusually may or may not come with a headache. Symptoms can include:
MAV symptoms tend to come in clusters so you may feel much better for a few days then the symptoms return. There is a link to triggers so you may find certain food, drinks or situations bring on a vestibular migraine.
How is Migraine Associated Vertigo diagnosed
Migraine Associated Vertigo can be diagnosed by taking a good history of the problem alongside a vestibular examination. To get to a diagnosis of MAV it is not uncommon to have been through the GP and onto a neurologist who completes series of medical test. These tests may include:
- MRI or CT scan
- Audiology tests
- Vestibular function tests- including calorics, balance testing, visual acuity
- Eye examination
- Reflexes and coordination tests

Lifestyle advice is very important with MAV and makes a huge difference to the frequency and severity of symptoms. Factors which impact MAV would be discussed following the vestibular assessment. These include sleep, exercise, stress, diet and pacing of your normal activates. Alongside advice on these areas coping strategies will be provided to help with MAV symptoms.
Vestibular rehabilitation consists of various eye, balance and task related home exercises. You will be asked to practice these regularly to help the body work hard to recognise normal vestibular signal. There is lots of evidence to support the use of vestibular rehabilitation with MAV and while this requires commitment to a home exercise program the results are significant.
