Summary

This trial is being done to determine whether a test that measures a "Visual Evoked Potential" can be used to improve treatments for patients with hearing loss.

Who is the study for?

This trial is for adults over 18 with varying degrees of hearing loss, who are patients or employees at Dartmouth Hitchcock Medical Center (DHMC), or from the local community. It's not for those with blindness, brain tumors, history of strokes, severe neurological issues, seizures, and excludes certain groups like prisoners and minors.

What is being tested?

The study tests if a 'Visual Evoked Potential' measurement can help in treating hearing loss by analyzing the brain's response to visual stimuli. Specifically looking at the P300 wave response after the initial reaction period to see if it can predict successful hearing aid or cochlear implant use.

What are the potential side effects?

Since this trial involves non-invasive testing of brain responses to visual cues without medication or surgery, there are minimal expected side effects. However, discomfort from wearing testing equipment may occur.

Treatment Details

Study Objectives

Study objectives can provide a clearer picture of what you can expect from a treatment.

Primary study objectives

Difference in mean VEP amplitude as measured by the maximum voltage reached by the P300 wave after presentation of stimulus before returning back to zero.

Difference in mean VEP latency as measured by onset time of the P300 wave from time of stimuli presentation.

Secondary study objectives

Difference in Controlled Oral Word Fluency Test scores between individuals with hearing loss and normal hearing controls.

Difference in Gap Detection Thresholds as a measure of auditory processing.

Difference in cochlear implant sound quality perception as measured by survey responses from participants with cochlear implants.
