Meniere's disease is a common cause of vertigo that becomes more common with age. Unfortunately, Meniere's disease and vestibular migraine have significant overlap and are sometimes difficult to diagnose. This is due to a lack of understanding of the true cause of Meniere's disease. Due to the lack of a biomarker (an objective test), the diagnosis of Meniere's disease has been based on clinical history and hearing loss. We are exploring ways to differentiate Meniere's disease and vestibular migraine, potentially through a lab test. In addition, identifying biomarkers may help early diagnosis and direct more personalized treatment strategies, especially early on before hearing loss occurs.

The purpose of this study is to evaluate participants Quality of Life (QOL) with their Cochlear implant (CI) through a variety of questionnaires and hearing tests.

There will be a pre-surgical visit as well as 3, 6, and 12 month post-surgery visits. In this study, the participants will take surveys and hearing tests at each visit. He or she will complete surveys on the computer through REDCap and the hearing tests will be completed in sound-attenuating booth using headphones in the Walton Research building on MUSC's campus. The study participation is complete once the participant has completed all 4 study visits.

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.

In the first arm of this study (Pro00063109) we developed a list of questions that will be utilized in a new quality of life questionnaire for cochlear implant users. We developed a survey to be used in the clinical setting based on these questions. We would like to gather data from a large number of implant users in order to validate the questionnaire. In the survey subjects are asked how hearing loss and having a cochlear implant affects their life. Enrolled subjects will complete the combined experimental survey paired with the current gold standard quality of life measures at two time points two weeks apart, greater than a year after receiving cochlear implantation.

As people get older, understanding speech with competing talkers can become more difficult. The MUSC Hearing Research Program is seeking healthy adults aged 50 to 89 years to participate in a research study investigating the connection between hearing and the brain. Payment is provided for participation, and scheduling is flexible. The study involves two to four visits. Participants must be able to complete an MRI.
