Listen Carefully: An Exploratory Study of the Association Between Listening Effort and Cognitive Function
In Brief
A clinical study evaluating Oticon Opn S 1 miniRITE hearing aid for Cognitive Impairment, Mild and Hearing Loss. Completed, enrolled 24 participants across 1 site.
Detailed Summary
This study aims to investigate the association between listening effort and cognitive function for both cognitively healthy individuals and for patients with Mild Cognitive Impairment (MCI) in mid-to-late stages of life, and furthermore to investigate listening effort and cognitive function after several weeks of hearing aid use. Listening effort is measured by the recording of peak pupil dilation during a sentence-final word identification and recall (SWIR) test, cognitive performance is measured using a battery of pen and paper cognitive tests, and hearing loss is measured with pure tone audiometry (PTA). A select number of participants in both the cognitively healthy and MCI group will be administered hearing aids, and the study will re-test both listening effort and cognitive performance.

Timeline
Interventions
Everyone who participates in Part 1 (listening effort testing and cognitive testing) will be invited to participate in Part 2 (hearing aids). It is not a requirement to participate in the administration, 6-week use, and re-testing procedures involved in Part 2 of the study. All cognitively healthy participants will be invited to participate, only MCI patients with a live-in informant will be given this opportunity. After ear measurement and dome and wire length selection, Oticon Opn S 1 miniRITE hearing aid fitting will occur wirelessly using Genie software, followed by hearing aid use instructions. The fitting will use Open domes, the standard NAL-NL2 protocol, and will increase gain seven steps on top of Real Ear Unaided Gain (REUG) from 750 Hz to 6 kHz.
