Can nose picking lead to Alzheimer’s disease? A study has a shocking answer

In a shocking turn of events, a new study has discovered a link between nose picking and neurological disorders, such as Alzheimer’s disease and dementia.

Researchers from Griffith University have shown how a bacterium called Chlamydia pneumoniae can lead to serious encephalopathy.

In a press release published by the university on Friday, the researchers suggested that the bacteria could travel directly from the olfactory nerve in the nose into the brain. This could lead to amyloid beta protein deposits in the brain that induce Alzheimer’s pathology.

Since the nerve extends from the nasal cavity to the brain, the bacteria can invade the central nervous system through this route. The resulting protein deposits are a hallmark of Alzheimer’s disease.

“We are the first to show that Chlamydia pneumoniae can travel directly up the nose to the brain where it can trigger Alzheimer’s-like pathology,” said Professor James St. Jon said in a press release.

He continued, “We saw this happen in a mouse model, and the evidence is potentially alarming for humans as well.

As a respiratory pathogen, the team said its link to late-onset dementia has become increasingly apparent thanks to their study, which was first published in the journal Scientific Reports in February this year.

The goal of the researchers in the study was to investigate whether the bacteria could rapidly invade the central nervous system within 3 to 7 days through the olfactory nerve in mice and lead to amyloid beta protein deposits in the brain.

“Chlamydia pneumoniae infects the olfactory mucosa, olfactory bulb, and cerebral cortex within 3 days of intranasal inoculation,” they wrote in their findings.

To confirm their findings, the team has been planning the next phase of research that could prove that the same pathway exists in humans and could lead to the same result.

“We need to do this study in humans and confirm whether the same pathway works in the same way.” It is a study that has been proposed by many, but not yet completed. What we do know is that these same bacteria are present in humans, but we haven’t figured out how they get there,” said St. Jon added.

Olfactory tests have been used as a potential tool to detect the risk of Alzheimer’s or dementia in humans because loss of smell is said to be an indicator of these neurological problems.

For now, St. John and his team strongly recommend picking your nose and pulling the hair inside it. Any damage to the inside of the nose can increase the chance that the bacteria will travel to the brain.
