Cognitive Impairment, Dementia, Hearing Loss
Conditions
Brief summary
Building upon the HEARS audiologist-community health worker (CHW) model, this study intervention will be delivered by a speech-language pathologist (SLP). The primary objective of the study is to develop and test an affordable and accessible hearing rehabilitative intervention that will be delivered by a SLP to individuals with cognitive impairment.
Interventions

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from Baseline in Neuropsychiatric Symptoms as assessed by the Neuropsychiatric Inventory (NPI-Q) | Baseline and 1 month post-intervention (immediate group). 1 month post-baseline (Delayed Group) | Scoring: Each of the 12 NPI-Q domains contains a survey question that reflects symptoms of that domain. Initial responses to each domain question are "Yes" or "No". If the response to the question is "No", the informant goes to the next question. If "Yes", the informant then rates both the Severity of the symptoms present within the last month on a 3-point scale and the associated impact of the symptom manifestations on them using a 5-point scale. The NPI-Q provides symptom Severity and Distress ratings for each symptom reported, and total Severity and Distress scores reflecting the sum of individual domain scores. Total NPI-Q severity score is the sum of individual symptom scores, ranges from 0 to 36. SEVERITY of the symptom (how it affects the patient): 1. = Mild (noticeable, but not a significant change) 2. = Moderate (significant, but not a dramatic change) 3. = Severe |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change from Baseline in Health-related Quality of Life as assessed by the Quality of Life in Alzheimer's Disease (QOL-AD) scale | Baseline and 1 month post-intervention (immediate group). 1 month post-baseline (Delayed Group) | Scoring for QOL-AD: Points are assigned to each item as follows: poor = 1, fair = 2, good = 3, excellent = 4. The total score is the sum of all 13 items. Total scores range from 13 to 52. |
| Change From Baseline in Hearing Specific Quality of life as assessed by the Hearing Handicap Inventory for the Elderly (HHIE-S) | Baseline and 1 month post-intervention (immediate group). 1 month post-baseline (Delayed Group) | Higher scores indicate increased hearing handicap. Scoring: 0-8 suggests no hearing handicap 10-24 suggests mild-moderate hearing handicap 26-40 suggests significant hearing handicap An increase in the score from baseline (a positive number) indicates a worsening in hearing handicap. |
