Nose-picking habit may ‘partially’ indicate Alzheimer’s risk: scientists

Sydney, Feb 5 (IANS) People who pick their nose frequently may have a higher risk of developing Alzheimer’s disease, according to a review of dozens of published studies.

Although scientists cannot identify precisely what causes Alzheimer’s disease, in the brains of patients, they have observed an accumulation of a protein called tau, which is associated with the body’s immune response.

But recent studies have pointed to the role of neuroinflammation, at least partially, in its pathogenesis.

In the new study, researchers from the University of Western Sydney in Australia “hypothesized that Alzheimer’s neuroinflammation may be partially caused by viral, bacterial, and fungal pathogens that enter the brain through the nose and olfactory system “.

Chronic nose picking, medically known as rhinotilexomania, introduces germs into the sensitive nasal cavity that cause inflammation in the brain, which has been linked to the onset of Alzheimer’s disease.

In the paper, published in the journal Biomolecules, the team showed support for this theory, suggesting that changes in the nasal environment caused by an overgrowth of germs could be the source of chronic and mild brain infections.

These infections can exist seemingly without symptoms, but they can cause inflammation and leave behind harmful plaques of proteins that contribute to the development of neurodegenerative diseases, including Alzheimer’s, the researchers said.

“One of the lessons learned from Covid is the value of hand hygiene through frequent hand washing and the use of hand sanitizers, and we suggest that these routine hygiene procedures be mandatory routine procedures for the collector of incurable nose,” the researchers wrote in the article. .
