"The Surprising Link Between Nose-Picking and Dementia Risk"
Recent headlines suggesting a link between nose picking and increased risk of Alzheimer's disease are based on a study conducted in mice, not humans. The study found that injecting C. pneumoniae bacteria into the noses of mice led to increased presence of the bacteria in the brain and clusters of amyloid β protein, a hallmark of Alzheimer's disease. However, experts caution against drawing conclusions for humans based on this study, as mice and humans differ in their response to these bacteria and the development of Alzheimer's disease. While the study raises interesting points, more robust research in humans is needed to determine the actual risk of nose picking in relation to dementia.
