Migraine Associated VertigoSymptomsThe manifestations of migraine-associated vertigo are quite varied and may include episodic true vertigo, positional vertigo, constant imbalance, and/or movement-associated dysequilibrium. Symptoms can occur prior to the onset of migrainous headache, during a headache, or, as is most common, during a headache-free interval. As such, many patients who experience migraine dizziness have vertigo or dizziness as the main symptom rather than headache. At the time of presentation to the doctor, dizziness symptoms may have been present for a few weeks or for several years. Symptoms may last for a few minutes or may be continuous for several weeks or months. In women, dizziness may often occur during the menstrual cycle. Patients with migraine-associated vertigo often have a long history of motion intolerance during car, boat, air travel, or all three. DiagnosisCurrently, no tests exist to make the diagnosis of migraine-associated vertigo. The diagnosis is made by clinical history. That is, the diagnosis is based upon the patient's symptoms as well as the patient's past medical and family history.
