About this trial

The purpose of this study is to determine whether people with MCI (Mild Cognitive Impairment) and healthy comparison subjects differ with respect to their ability to hear soft sounds and how their brain understands and processes sound. The investigators are also evaluating, within those with MCI, whether the hearing tests are associated with neurocognitive functioning. The investigators are interested in learning whether changes in cognition in those with MCI can be detected using tests of how the brain processes sound. The investigators hypothesize that participants with MCI will score worse on both hearing tests and neurocognitive tests than participants without MCI. Participants are asked to complete multiple types of hearing tests, take a series of neurocognitive tests, and complete a few questionnaires.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Adults diagnosed with or suspected to have MCI (for MCI group) or are cognitively normal (for Control group)

Absence of other risk factors that might affect CAP (Central Auditory Processing) performance (e.g., active ear infections, congenital developmental delay, severe hearing loss)

Age 55-80

Normal hearing sensitivity (<40 dB HL Pure Tone Average (average of 500, 1000, 2000 Hz) thresholds bilaterally

Disqualifiers

Active ear infections or abnormal middle ear pathology

Other health condition prohibiting the completion of the CAP test battery

Mild to profound peripheral hearing loss (>40 dB (decibel) HL (hearing loss) Pure Tone Average (average of 500, 1000, 2000 Hz) bilaterally

Adults unable to consent

Trial population

The community in and around Lebanon, NH and patients from DHMC.

Trial outcomes

Primary outcomes

1

Hearing-in-Noise Test Performance

The performance for Hearing in Noise Tests (HINT) between energetic masking and 2-talker informational masking (IM). Performance will be measured by the lowest signal-to-noise ratio (volume at which sentences are presented compared to background noise volume) that can be heard by the participant.

Time frame
1 time point (takes 15 minutes)
2

Triple Digit in Noise Test Performance

Performance for the behavioral Triple Digit (TDT) between energetic masking and 2-talker informational masking (IM). Performance will be measured by the lowest signal-to-noise ratio (volume at which digits are presented compared to background noise volume) that can be heard by the participant.

Time frame
1 time point (takes 15 minutes)
3

Size of auditory neural response in background noise

The change in amplitude of neural response between energetic masking and 2-talker informational masking (IM).

Time frame
1 time point (takes 45 minutes)
4

Timing of auditory neural response in background noise

The change in latency of neural response between energetic masking and 2-talker informational masking (IM).

Time frame
1 time point (takes 45 minutes)
