Patients with chronic or episodic recurrent dizziness will track their vestibular symptoms with every episode in the iPhone application, Vertige. They will track their symptoms at the conclusion of every episode for a total of six (6) months. The app has a geolocation software that will pair environmental data (barometric pressure, temperature, humidity, etc.) with symptoms. We will then analyze the data to evaluate for associations.

We are interested in seeing which biomarkers are involved in the pathophysiological pathways of vestibular migraine and Meniere's disease. To this end, we will have eligible patients undergo peripheral blood draws to establish a biobank. The blood samples collected will undergo in vitro testing to determine the cytokine profiles of the immune cells and will also undergo genetic testing. Data and samples collected will be used for future studies as well.
