Migraines in general are considered to be a neurological syndrome. According to the ICHD International Classification of Headaches Disorders it is estimated that 11% or (303 million) of the global population experiences migraines. The ICHD recognizes vestibular migraines as a subtype of migraines. A large percentage of migraine patients do not have a headache as their dominant symptom. These patients describe symptoms that include constant dizziness, movement triggered dizziness, nausea and vomiting, blurred vision, light +/or noise sensitivity, imbalance, anxiety and difficulty concentrating. These symptoms can occur with a headache, after a headache or without any headache at all.

Some people experience auras prior to a migraine. A migraine aura can consist of attacks of reversible focal neurological symptoms that lasts less than 60 minutes. Symptoms can include: flashing lights, spots or lines, loss of vision, numbness, pins and needles, dysphagic speech disturbance (difficulty speaking) and or motor weakness.
