Clinical Trial Summary

This research study is investigating whether people with Alzheimer's disease experience more changes to voice and swallowing than their healthy age-matched peers. The prevalence of swallowing impairments in moderate-severe Alzheimer's Disease is high (85-93%) and voice is also often negatively impacted by Alzheimer's disease. The overall objective of this study is to evaluate the voice and swallowing function of adults with and without Alzheimer's disease. The investigators will also be involving the primary caregivers of individuals with Alzheimer's that are enrolled in the study to better understand the impact of voice and swallowing impairments on the primary caregivers of those with Alzheimer's Disease. Healthy adults and individuals with Alzheimer's disease will: - undergo tests of cough, voice, and swallow function - undergo tests of grip and tongue strength - complete questionnaires Caregivers of individuals with Alzheimer's disease will also complete questionnaires.


Description:

This study will involve one in-person research visit that will last approximately 1-1.5 hours and will consist of a screening, cough testing, swallow function testing, vocal function testing, assessments of hand grip and tongue strength, and completion of questionnaires. Caregivers of those with Alzheimer's disease will also complete questionnaires at this initial visit. Following the first research evaluation visit, individuals will be contacted via email or by phone annually for two consecutive years to complete the same questionnaires completed at the initial visit.

Outcome

Type Measure Description Time frame Safety issue
Primary Swallowing safety The penetration aspiration scale is a validated 8-point ordinal rating scale that measures the depth of airway invasion and the patient's response during swallowing. Scores range from 1 to 8 with a score of 1 indicating a safe swallow (best score) and 8 indicating silent aspiration (worst score). During baseline visit at time of enrollment.
Primary Voluntary cough peak expiratory flow A measure of cough strength During baseline visit at time of enrollment.
Primary Vocal fold bowing index Vocal fold bowing will be completed as described by Bloch and Behrman. During baseline visit at time of enrollment.
Secondary Swallowing and Eating Related Fatigue Questionnaire (SERF) Scores on the SERF range 0-48 with higher scores indicating greater impairment. During baseline visit at time of enrollment, 1 year after baseline visit, 2 years after baseline visit.
Secondary Swallowing Related Quality of Life Questionnaire (SWAL-QOL) Scores on the SWAL-QOL range from 0-100 with lower scores indicating greater impairment. During baseline visit at time of enrollment, 1 year after baseline visit, 2 years after baseline visit.
Secondary Voice Handicap Index (VHI) The VHI contains 30 questions, and scores range from 0-120, with higher scores indicating greater perceived voice handicap. During baseline visit at time of enrollment, 1 year after baseline visit, 2 years after baseline visit.
Secondary Aging Voice Index (AVI) he AVI consists of 23 questions, with scores ranging from 0-92. Higher scores indicate a greater effect of dysphonia on quality of life. During baseline visit at time of enrollment, 1 year after baseline visit, 2 years after baseline visit.
Secondary Grip Strength Grip strength be used to quantify clinical frailty using a digital hand dynamometer. During baseline visit at time of enrollment.
Secondary Tongue strength Tongue strength will be assessed using the Iowa Oral Pressure Instrument (IOPI). During baseline visit at time of enrollment.
Secondary Clinical frailty scale The clinical frailty scale (scores 1-9) will be used to classify frailty with higher scores indicating greater impairment. During baseline visit at time of enrollment, 1 year after baseline visit, 2 years after baseline visit.
Secondary Caregiver Analysis of Reported Experiences with Swallowing Disorders (CARES) Questionnaire Scores on the CARES range from 0-26 with higher scores indicating greater caregiver burden. During baseline visit at time of enrollment, 1 year after baseline visit, 2 years after baseline visit.
Secondary Caregiver Self-Assessment Questionnaire Scores range from 0-16 with higher scores indicating greater caregiver burden During baseline visit at time of enrollment, 1 year after baseline visit, 2 years after baseline visit.
