This research study is looking into how swallowing changes in adults with Alzheimer's disease (AD) compared to those without AD. We know that many people with moderate to severe AD have trouble swallowing, but we don't fully understand how these problems develop over time. This study aims to evaluate swallowing function in both groups. We are also involving primary caregivers of individuals with AD to understand how swallowing difficulties impact them. You may be able to join if you are an adult aged 60 or older, with or without an AD diagnosis confirmed by a neurologist. The main goal is to measure swallowing safety during a single visit.

Study design

This is an observational study planning to enroll 240 participants. It compares swallowing function in adults with and without Alzheimer's disease.

What's involved

You would have one in-person research visit lasting about 1 to 1.5 hours. This visit includes screening, cough and swallow function tests, hand grip and tongue strength assessments, and questionnaires.

Compensation

Not stated in the trial record.

Follow-up

Swallowing safety is measured during the baseline visit at the time of enrollment, so there is no specified follow-up period after this visit.
