About this trial

This research study is investigating whether people with Alzheimer's disease (AD) experience more changes to swallowing than their healthy age-matched peers. The prevalence of swallowing impairments in moderate-severe AD is high (85-93%), yet little is known about how swallow function evolves throughout the disease course in people with AD. The overall objective of this study is to evaluate swallowing function in adults with and without Alzheimer's disease. The investigator will also be involving the primary caregivers of individuals with Alzheimer's that are enrolled in the study to better understand the impact of 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 and swallow function * undergo tests of grip and tongue strength * complete questionnaires

Caregivers of individuals with Alzheimer's disease will also complete questionnaires.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

adult ≥60 years old

diagnosis of AD by a neurologist (confirmed with imaging, spinal tap, behavioral testing)

no prior history of other neurological diseases (aside from stroke which has resolved with no current symptoms)

no prior history of respiratory diseases

Disqualifiers

individual <60 years old

Diagnosis of another type of dementia

History of neurological/respiratory diseases

History of head and neck surgery/head and neck cancer/radiation to head and neck region

Trial population

The overall objective of this proposal is to evaluate swallow function in 80 healthy adults and 80 individuals with AD and to evaluate caregiver perceptions of swallow function and burden in 80 caregivers of individuals with AD. Thus, this study will enroll healthy adults, individuals with AD, and caregivers of individuals with AD.

Trial outcomes

Primary outcomes

1

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).

Time frame
During baseline visit at time of enrollment.

Secondary outcomes

1

Voluntary cough peak expiratory flow

A measure of cough strength

Time frame
During baseline visit at time of enrollment
2

Grip strength

Grip strength be used to quantify clinical frailty using a digital hand dynamometer.

Time frame
During baseline visit at time of enrollment.
3

Tongue strength

Tongue strength will be assessed using the Iowa Oral Pressure Instrument (IOPI).

Time frame
During baseline visit at time of enrollment.
4

Swallowing and Eating Related Fatigue Questionnaire (SERF)

Scores on the SERF range 0-48 with higher scores indicating greater impairment.

Time frame
During baseline visit at time of enrollment.
