Nasal biopsy study for Alzheimer's and smell disorders
Part of Brain & nervous system, Mental health clinical trials.
This study takes a small tissue sample from inside your nose to look for changes linked to Alzheimer's disease or smell problems. It may help us better understand how these conditions affect the brain.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You can be between 18 and 80 years old for the Alzheimer's group, or 18 or older for the smell disorder group.
- You have either early Alzheimer's (with normal thinking but positive biomarker tests) or a confirmed Alzheimer's or dementia diagnosis, OR you have a smell disorder or are already having nasal surgery.
- You cannot be allergic to Afrin or tetracaine (numbing sprays used in the procedure).
- You do not have Parkinson's disease or active sinus or nasal problems that would make the biopsy unsafe.
- You can have a tiny camera look inside your nose and understand the consent form.

Other trials that look related to this one.
This trial tests whether steroid nose drops placed in the upper part of the nose, combined with smell training (sniffing different scents), can help people who lost their sense of smell after an infection. The goal is to see if this combination improves smell recovery better than training alone.
This study is looking at how the brain processes smells in people with chronic sinusitis and nasal polyps who have a reduced sense of smell. It will compare brain images (MRI) of patients who are starting biologic treatment and those who are not, to understand how these medications might affect the brain.
This trial uses remote, at-home (or remote) smell-based testing to help researchers assess health in people with preclinical Alzheimer’s disease and in control participants. It may help by showing how well smell-related changes can signal disease status over time.
This study looks at why people with nasal polyps lose their sense of smell and how it might come back. You may be able to join if you have had nasal blockage, runny nose, smell loss, or facial pain for at least 12 weeks, have polyps seen inside your nose, and are using a steroid spray regularly.
This study looks at how changes in a small area inside the nose (called the olfactory cleft) affect smell in people with chronic sinusitis. It aims to understand why some people with sinusitis have trouble smelling, which could lead to better treatments.
This study tests whether a daily smell training routine can help improve your sense of smell. It is open to adults with any kind of smell loss or problem, including those with conditions like COVID-19 or head injury, but not certain brain diseases.
