Sun Health Explainer: Dementia and Alzheimer’s disease
THOUGH it's frowned upon in public, most of us will sometimes stick a finger up our nostril when we think nobody's looking.Chronic nose picking could allow bacteria to travel up your nasal cavity to your brain, resulting in inflammation that could cause Alzheimer's diseaseThe theory behind it is that digging into your schnoz could allow bacteria, viruses and fungi to enter the brain, where it can cause inflammation.
"We propose more investigation to understand the association of nose picking with Alzheimer's disease in the form of case-control studies with larger sample populations.", previously said that the brain-robbing disease responsible for memory loss and cognitive decline "is a complex neurodegenerative disorder" that can be caused by "many possible factors".
"Emerging research has explored the possible involvement of external, invading pathogens in starting or accelerating the neuroinflammatory processes in Alzheimer's disease," they added.of thousands of studies, they said the olfactory system - which includes the nasal cavity and nerve cells involved in our sense of smell - is "a plausible route" for pathogens to enter the brain.
However, the Western Sydney University team did question whether nose-picking was the cause of Alzheimer's, or whether the brain-robbing disease caused people to take up unhealthy habits leading to brain inflammation.
