Fingering in the nose It is a very bad habit that exposes people to various bacteria. This actionAlzheimer’s disease and dementia also increases
According to the latest research, Fingering in the nose Can Risk of Alzheimer’s and dementia increase New research shows that the bacterium Chlamydia pneumoniae is one of the main causes of respiratory tract infections such as pneumonia. Details of this study were published earlier this year in the journal Scientific Reports.

Fingering in the nose and its relationship with dementia
New research on mice showed that a bacterium can through Olfactory nerve in the nose It travels to the brain, where it creates markers that are indicative of Alzheimer’s disease.
More precisely, what the researchers found was that the bacteria “Chlamydia pneumoniae” (Chlamydia pneumoniae) from the nerve extending between the nasal cavity and the brain as a direct route to reach Central nervous system Uses. The brain cells then reacted by depositing the beta-amyloid protein, a key precursor to the development of Alzheimer’s disease. These findings are in accordance with previous researches in this field.
Professor James St. John, director of the Colem Jones Neurobiology and Stem Cell Research Center and one of the authors of the study, says:
For the first time, we showed that Chlamydia pneumoniae can directly enter the brain through the nose and cause effects that look like Alzheimer’s disease. We have seen this happen in the mouse model and according to this evidence, this issue can be dangerous for humans as well.
Fingering in the nose It increases the risk of dementia. The olfactory nerve in the nose is directly exposed to the air and provides a short path to the brain that bypasses the blood-brain barrier. Bacteria and viruses use this pathway as an easy way to enter the brain.

The researchers of this center are planning the next stage of research and their goal is to prove the existence of a similar pathway in humans. “We need to do this study in humans and confirm if the same pathway works in the same way,” says Prof St John. Many people have suggested this research; But it is not yet completed. What we know is that these same bacteria are also present in humans; But we have never found out how they get to the brain.”
Professor St. John suggests a few simple things to care for the lining of the nose:
Picking your nose and pulling nose hairs is not a good idea. You don’t want to damage the inside of your nose, and picking your nose and pulling hair can do that. If you damage the lining of your nose, you can increase the number of bacteria that can enter your brain.
“Olfactory tests may also act as detectors of Alzheimer’s and dementia,” says Professor St. John. Because losing the sense of smell is one of the early signs of Alzheimer’s.” He suggests that smell tests from the time a person turns 60 can be useful as an early detector.
The scientist added:
When you are older than 65, your chances of developing Alzheimer’s increase as you age. However, we are investigating other causes as well; Because it is not only age that is effective in the disease; But environmental exposures are also important, and we think that bacteria and viruses are also very important.
