Hand Hygiene Matters

Health professionals emphasize the importance of regular hand washing, especially during flu season. This precaution is essential not only during outbreaks but also when new viruses arise in the community. To minimize the risk of infection, it's advisable to avoid touching your face, as even minor abrasions on the skin can allow germs to enter your body.

Researchers are currently gearing up to conduct studies involving human participants, following initial trials on mice, which closely resemble humans genetically. The encouraging results from these animal studies have led scientists to anticipate similar, if not more severe, outcomes in humans.

"This genetic similarity makes mice particularly useful for research, as they are easier to manipulate genetically compared to other animals like worms or dogs." — ED Times

Bacteria and Cognitive Decline

The Research Overview

A study conducted by Griffith University revealed that certain bacteria can migrate from the nasal passages to the brain. What is particularly alarming is that this transfer can occur without any skin breaks in the nasal cavity. The bacteria utilize the olfactory nerve as a pathway to access the brain.

In their experiments, researchers observed that the bacteria left distinctive markers, allowing them to trace its journey. After a period within the skull, the mice exhibited signs indicative of Alzheimer's disease.

Key Findings from the Study

The bacteria implicated in this study is Chlamydia pneumoniae, which travels along the nerve connecting the nasal cavity to the brain, ultimately infiltrating the central nervous system. In response to the invasion, brain cells attempt to protect themselves, leading to the accumulation of amyloid beta protein—commonly found in the brains of Alzheimer's and dementia patients.

Professor James St John, head of the Clem Jones Center for Neurobiology and Stem Cell Research, co-authored this groundbreaking research. He warns against habits that might increase the risk of cognitive decline.

"Engaging in nose picking or hair plucking can be harmful. Any damage to the nasal lining could facilitate bacterial entry into the brain." — Professor James St John

If you must pick or pluck, ensure your hands are clean and be gentle to avoid skin breaks that could heighten sensitivity to airborne contaminants.

"Smell tests might serve as early indicators for Alzheimer’s and dementia. A decreased sense of smell could signal these conditions, particularly for those over 60, as the risk escalates with age. Environmental factors also play a role, with bacteria and viruses being significant contributors." — Professor James St John
