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.

Older adults typically have trouble identifying the speech they hear, especially in noisy environments. Fortunately, compared to younger adults, older adults are better able to compensate for difficulties identifying the speech they hear by recruiting the visual system. However, the extent to which older adults can benefit from visual input, and how this influence relates to age-related changes in brain structure and function, have not been thoroughly investigated. The general purpose of this study is to determine how age-related changes in brain structure and function affect how well people hear and see. This study seeks participants with normal hearing to mild hearing loss, who also have normal or corrected-to-normal vision.
