A new study conducted by researchers at Western Sydney University has found a concerning link between frequent nose-picking and a higher risk of developing Alzheimer’s disease. The study, which reviewed numerous published studies on neurological diseases, suggests that chronic nose-picking, known as rhinotillexomania, introduces germs into the nasal cavity, leading to inflammation in the brain and potentially contributing to the onset of Alzheimer’s.
The report, published in the journal Biomolecules, highlights the role of neuroinflammation in Alzheimer’s disease and proposes that viral, bacterial, and fungal pathogens entering the brain through the nose and olfactory system could be a contributing factor. The researchers argue that an overgrowth of germs in the nasal environment can cause chronic, mild brain infections that may go unnoticed but leave harmful protein plaques behind, contributing to the development of neurodegenerative diseases like Alzheimer’s.
Alzheimer’s disease affects over 6 million people worldwide, with the majority being individuals aged 65 and older. While the exact cause of the disease is still unknown, scientists have observed a buildup of a protein called tau in the brains of patients. This protein is associated with the body’s immune response, and when immune cells are triggered too frequently, it can lead to inflammation and various diseases.
The authors of the study support this theory and emphasize the importance of maintaining a healthy nasal environment to reduce the risk of developing Alzheimer’s. They found common pathogens such as pneumonia-causing bacteria, herpes virus, coronavirus, and the cat-derived parasite Toxoplasma gondii in the brains of people with Alzheimer’s. These pathogens can enter the brain through the nose and contribute to the development of neurodegenerative diseases.
In light of these findings, the researchers strongly urge individuals to refrain from picking their noses. However, if nose-picking is unavoidable, they recommend thoroughly washing hands before doing so. The importance of hand hygiene is emphasized, with the researchers drawing a parallel to the lessons learned from the COVID-19 pandemic, where frequent hand washing and the use of hand sanitizers have been crucial in preventing the spread of the virus.
In conclusion, this groundbreaking study sheds light on a previously unknown risk factor for Alzheimer’s disease. The link between chronic nose-picking and the introduction of germs into the nasal cavity, leading to brain inflammation, highlights the importance of maintaining a healthy nasal environment. By practicing regular hand hygiene and refraining from nose-picking, individuals can potentially reduce their risk of developing this debilitating neurodegenerative disease.
