The most prevalent kind of dementia is Alzheimer’s, and its onset is considered to be influenced by both heredity and the environment. Pathogens may possibly have a role in the progression of Alzheimer’s disease, according to research, although it is yet unknown how they reach the brain.
Now, research from Australia has discovered that one bacterium, Chlamydia pneumonia, causes amyloid beta plaques, which are indicative of Alzheimer’s disease, by entering the brain through the olfactory nerve from the nose.
According to scientists, nose-picking harms the nasal mucosa, which makes it simpler for germs to infiltrate the olfactory nerve and the brain.
Most people consider nose-picking to be an annoying but harmless behavior. Research from Griffith University in Queensland, Australia, however, raises the possibility that the exercise may not be as risk-free as first believed.
The study, which was released in Nature Scientific, demonstrates how germs may enter the brain through the olfactory nerve in mice by injuring the nasal canal.
Certain bacteria encourage the deposition of amyloid beta protein once they enter the brain, potentially triggering the onset of Alzheimer’s disease (AD).
Many of the symptoms of AD, including memory loss, language difficulties, and erratic behavior, are considered to be caused by plaques formed by amyloid beta.
