Nose
It might sound like a small habit that is harmless.However, a study reveals the possibility of this habit with serious brain diseases such as
Alzheimer’s
.
Research published in 2022 by a team of scientists from Griffith University, Australia, found that when someone nose to injure the tissue in the nose, certain bacteria can have easier paths towards the brain.
This mechanism is observed in mice, and the brain response that occurs is similar to the early signs of Alzheimer’s disease.
The bacteria in question are
Chlamydia pneumoniae
, which can infect humans and cause pneumonia.Interestingly, this bacterium is also found in most of the human brain that experiences advanced dementia.
In the experiment, the researchers showed that in mice, this bacterium was able to spread through the olfactory nerve, the channel that connects the nasal cavity with the brain.When the thin tissue on the roof of the nasal cavity (nasal epithelium) is damaged, nerve infections become more severe.
The damage triggered the brain of mice to produce more amyloid-beta protein.This protein is generally released in response to infection, and its lumps are often found in high amounts of the brain of sufferers of Alzheimer’s.
“We are the first party to show that
Chlamydia pneumoniae
Can directly enter the brain through the nose and trigger a pathology similar to Alzheimer
Science Alert
.
“We see this in the rat model, and the proof is quite worrying if the same thing happens to humans.”
The thing that surprised scientists is the speed of bacteria infecting the central nervous system of the rat, which is only in 24 to 72 hours.According to St. John, the nose can be a fast path for bacteria and viruses to reach the brain.
Potential danger to pick up
Although it has not been proven the same effect on humans, this finding is considered an important guide in understanding Alzheimer’s, neurodegenerative disease which is definitely still mysterious.
“We need to do research on humans to ascertain whether this pathway works in the same way,” St. John said.
“This bacterium does exist in humans, but we don’t know how they get to the brain.”
Another fact to remember, nose is not a rare habit.It is estimated that nine out of ten people did it, even some animal species did it.
However, the researchers suggested to avoid nose or pulling nose hair, in order to prevent damage to the nose protective tissue.
Alzheimer himself is a very complex disease, and the risk factor is not only over 65 years old.Environmental exposure, including bacterial and virus infections, is believed to play a role in developing this disease.
“Bacteria and viruses are likely to have an important role,” said St. John.”Therefore, maintaining nose health can be a simple step to protect the brain,” he concluded.
