Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults over 18 years old with varying degrees of hearing loss and central auditory processing dysfunction.

Probably not a fit

Patients with known brain pathology, severe neurological disorders, seizure history, or blindness may not benefit from this study.

What this trial studies

This research aims to explore the use of Visual Evoked Potential (VEP) testing to assess brain responses in individuals with hearing loss. Participants will undergo two appointments where they will complete visual tests, VEP testing, auditory assessments, and cognitive evaluations. The study focuses on measuring the P300 wave, a specific brain response to new visual stimuli, to determine its relevance in improving treatments for hearing loss. The testing will be conducted at Dartmouth Hitchcock Medical Center, utilizing non-invasive electrodes to monitor brain activity.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment strategies for individuals with hearing loss by providing insights into their brain's response to visual stimuli.

How similar studies have gone: While the use of VEP testing is established in other conditions, its application in individuals with hearing loss is novel and has not been extensively studied.
