Investigating smell loss in Alzheimer's Disease patients
Biopsy-based single cell assays for olfactory sensory changes in an Alzheimer's Disease cohort
This study is looking at how losing your sense of smell might be connected to Alzheimer's Disease, and it's for people who have early signs or symptoms of the disease; researchers will take small samples from the nose to learn more about the changes happening in the brain and how they could help find new treatments.

What this research studies
This research focuses on understanding how changes in the sense of smell, known as anosmia, relate to Alzheimer's Disease (AD). By collecting olfactory biopsies from individuals with preclinical or symptomatic AD, researchers will analyze the molecular and cellular mechanisms involved in olfactory loss. The study employs advanced techniques like single cell RNA sequencing to compare the genetic profiles of olfactory neurons and immune cells in different stages of the disease. This approach aims to uncover insights that could lead to new treatments for olfactory disorders and AD.
Who could benefit from this research
Good fit: Ideal candidates for this research include individuals who are experiencing early symptoms of Alzheimer's Disease or have a genetic predisposition, such as those with the APOE-e4 allele.
Not a fit: Patients with advanced Alzheimer's Disease or those without any olfactory dysfunction may not benefit from this research.
Why it matters
Potential benefit: If successful, this research could lead to the development of disease-modifying treatments for Alzheimer's Disease and related olfactory disorders.
How similar studies have performed: Previous research has shown that olfactory dysfunction can be an early indicator of Alzheimer's Disease, suggesting that this approach may yield valuable insights.
