Exploring breath biomarkers for diagnosing Alzheimer's Disease
Antemortem biomarkers in nasally exhaled breath: A potential novel, noninvasive human diagnostic technique for Alzheimer’s Disease
This study is looking at whether we can find signs of Alzheimer's Disease in the breath you exhale through your nose, which might help us diagnose the condition in a simple and non-invasive way.

What this research studies
This research investigates whether biomarkers for Alzheimer's Disease can be detected in nasally exhaled breath. The team will analyze the presence of the neural protein Tau, which preliminary findings suggest is more concentrated in nasal breath compared to oral breath and correlates with the severity of dementia. By focusing on nasally exhaled samples, the study aims to leverage the unique anatomy of the nasal cavity, which may provide direct access to neural biomarkers. This noninvasive approach could lead to a new diagnostic technique for Alzheimer's Disease.
Who could benefit from this research
Good fit: Ideal candidates for this research are individuals experiencing cognitive decline or symptoms related to Alzheimer's Disease.
Not a fit: Patients with other forms of dementia unrelated to Alzheimer's may not benefit from this research.
Why it matters
Potential benefit: If successful, this research could provide a simple and noninvasive method for early diagnosis of Alzheimer's Disease.
How similar studies have performed: While research on exhaled breath biomarkers is ongoing, this specific focus on nasally exhaled breath for Alzheimer's diagnosis is relatively novel.
