Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Because (1) the neuropsychiatric symptoms associated with dementia could be exacerbated by poor communication resulting from hearing loss and (2) it has been widely accepted that hearing aids (HAs) are effective in improving communication function and reducing the psychosocial consequences associated with hearing loss for older adults without dementia, it seems reasonable to use HAs to treat the hearing loss of adults with Alzheimer's Disease and related dementias (ADRD). However, it has been argued that because the pathology of ADRD could involve central auditory pathways and nuclei, HAs-the devices that improve audibility at the peripheral level of the auditory system-may not be an effective management for ADRD. To date there is no high-quality evidence to support or negate the benefit of HA intervention on adults with dementia in reducing communication difficulty, dementia-related symptoms, and caregiver burdens. Therefore, the benefit of HA intervention on adults with ADRD remains unknown. Further, the best service model to provide HAs for older adults with ADRD is unknown. On one hand, it is likely that customized HAs fitted by audiologists using best practices could generate optimal outcomes. However, implementing the best-practice audiology services is challenging in this population. On the other hand, recent literature suggests that audiologists could fit low-cost, pre-programmed, non-customized amplification devices to adults with ADRD to reduce the cost of HA intervention, while yielding reasonable outcomes.To date there is no high-quality research rigorously examining the outcome, value, and candidacy of different HA service-delivery models for older adults with ADRD.
This is a pilot study with the aim of evaluating the feasibility of the procedures of a future clinical trial that will help determine the impacts of hearing aid interventions on older patients with ADRD. We expect that at least a total of 30 patients will complete the pilot study. The collected data will provide valuable information for us to formulate or revise the hypotheses, conduct power analysis, and finalize the research protocol for the future clinical trial.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Audiologist-Based
In this group, the audiologist-based fitting will be used to provide hearing aids.
Audiologist-based fitting
Hearing aids will be fitted by audiologists using established procedures.
Service-Only
In this group, hearing aids that have minimum amplification will be fitted by audiologists.
Service-only Fitting
This intervention group is designed to explore the contribution of amplification devices in hearing aid intervention, which consists of devices and services. In this intervention group, audiological services plus hearing aids that provide minimum amplification will be provided. Specifically, patient participants in this group will receive audiological services (e.g., counselling and education), except that the hearing aids will be set to provide no amplification other than what is needed to overcome any sounds that are dampened by the earpieces.
Device-Only
In this group, hearing aids will be provided with minimum services from audiologists.
Device-only fitting
This intervention group is designed to explore the contribution of amplification devices in hearing aid intervention, which consists of devices and services. The patient participants in this intervention group will have minimum services regarding the pre-fitting, selection, and orientation of the hearing aids. The participants will have a hearing evaluation, including pure-tone audiometry. The audiologist will select the amplification characteristics and non-custom ear piece based on the audiogram. The audiologist will then briefly orient the participant on how to use the hearing aids and counsel on how to optimize their performance.
