A recent study conducted by researchers from Griffith University, Australia, has found a potential link between nose-picking and the development of Alzheimer's disease.
The study, conducted on mice, revealed that Chlamydia pneumoniae, a bacterium associated with pneumonia and late-onset dementia, can travel up the olfactory nerve from the nasal cavity into the brain. This process was accelerated when the nasal epithelium was damaged, potentially allowing the bacteria to trigger the formation of amyloid-beta plaques—proteins often associated with Alzheimer's.
The bacteria's movement into the brain triggered increased deposits of amyloid-beta in the mice, suggesting that infections could contribute to Alzheimer's-like pathology. This pathway is alarming, as the bacteria reached the central nervous system within 24 to 72 hours. Although this research is based on animal models, it raises concerns about human exposure to such bacteria, especially through habits like nose-picking, which may damage protective tissues. Further human studies are needed to confirm whether similar mechanisms are at play.
