- Brief Summary
Early Age-Related Hearing Loss Investigation (EARHLI) is a single site study that will randomize late middle age adults to either a hearing intervention (including hearing aids) or a health education intervention. Participants will be followed for 1 year. This study will provide information on reducing cognitive decline in those at risk for Alzheimer's Disease and Alzheimer's Disease Related Dementias (AD/ADRD).
- Detailed Description
EARHLI will be a phase II 1:1 randomized controlled trial of a hearing intervention (including prescription hearing aids) versus a health education program. Participants must be 55-75 years old and have early-stage age-related hearing loss and amnestic mild cognitive impairment. The trial will last 1 year and occur at a single site (Columbia University Irving Medical Center). Outcome measurements will include cognition, social engagement, and change in brain organization/connectivity. Assessments will occur at study start, 6 months, and 12 months. A total of 150 participants will be enrolled (75 per intervention group). Participants will also have a hearing test and a blood test. Approximately half of participants will have two MRI scans. As part of participating, all participants will get prescription hearing aids, either at study start or end.

Group Intervention Description Health Education Intervention Health Education Intervention Participants will receive a modified health education program on healthy aging. It will match the number and length of sessions as the hearing intervention, including compliance/phone checks. Participants will be on a waitlist to obtain hearing aids without fee at the end of their 12-month participation. Hearing Intervention Hearing Intervention Participants will receive 4 sessions across 8 weeks with a later booster session and hearing aid fitting. Each session will take \~75 minutes.
- Primary Outcome Measures
Name Time Method Cohens Social Network Index (SNI) Score Week 0, Week 28, Week 52 This is the Social Engagement and Related Socialization test # 4: Evaluates Social Relationships. Scored from 1 - 12. Higher score indicates a larger number of social roles in which the respondent has regular contact.
Delayed Recall Log Memory IIa, (DRLM) Score Week 0, Week 28, Week 52 This is the Cognitive Performance Test # 2 ADCS-PACC 2: Evaluates Episodic Memory. Scoring from 0 - 25 and a higher score translates into a preserved function of the episodic memory.
Trail Making Test Part B, (TMTB) Score Week 0, Week 28, Week 52 This is the Cognitive Performance test # 5 Evaluates Episodic Memory. Scored in terms of the time, in seconds, required to complete the trail. 300 seconds = maximum amount of time. The less seconds it takes to complete the trail, the better performance/ episodic memory.
Activities of Daily Living for Mild Cognitive Impairment, (ADCS-ADLPI) Score Week 0, Week 28, Week 52 This is the Cognitive Performance test # 6: Evaluates the ability of patients to perform Activities of Daily Living. Section a. Scored from 0 - 45: Items 1 to 15. Higher score for each activity equals better performance. Section b. Scored from 0 - 5. Item 16 to 20. Higher score equals better performance
Social Activity Frequency Week 0, Week 28, Week 52 This is the Social Engagement and Related Socialization test # 1: Evaluates frequency of social activity participation. Participants are asked on a 5-point scale how often during the past 6 months they engaged in 6 common activities involving socialization. A composite score is created
Brain MRI Measures Week 0, Week 52 Approximately 50% of all participants (random selection) will have a functional brain MRI.
Free and Cued Selective Reminding Test (FC-SRT) Score Week 0, Week 28, Week 52 This is the Cognitive Performance Test # 1 ADCS-PACC 1: Evaluates Episodic Memory. Scoring from 0 - 48 and a higher score translates into a preserved function of the episodic memory.
Digit Symbol Substitution Test, (DSST) Score Week 0, Week 28, Week 52 This it the Cognitive Performance test # 3 ADCS-PACC 3: Evaluates speed of processing. Scoring from 0 - 91 and a higher score relates to better performance and speed of processing.
Mini-Mental State Examination 2, (MMSE-2) Score Week 0, Week 28, Week 52 This is the Cognitive Performance test # 4 ADCS-PACC 4: Evaluates Global Cognition. Scoring from 0 - 30 and a higher score relates to preserved Global Cognition.
University of California Loneliness Scale (ULS) Score Week 0, Week 28, Week 52 This is the Social Engagement and Related Socialization test # 5: Evaluates Individuals perception of loneliness. The total score ranges from 20 - 80. Higher scores indicate higher loneliness.
Ability to Participate in Social Roles and Activities (APSR) Score Week 0, Week 28, Week 52 This is the Social Engagement and Related Socialization test # 2: Evaluates Social Activity Participation. Scored from 8 - 40 a higher score translates into higher levels of social participation.
Community Integration Measure (CIM) Score Week 0, Week 28, Week 52 This is the Social Engagement and Related Socialization test # 3: Evaluates Community Integration/Participation. Scored from 10 - 50. Higher scores indicate higher levels of community integration and participation.
