Can your nose-picking habit lead to Alzheimer’s? What science says | – Times of India


Nose-picking, often dismissed as a harmless habit, has come under scrutiny due to a recent study published in Biomolecules, revealing a potential link to Alzheimer’s disease. While Alzheimer’s is already a concerning condition affecting millions globally, this new research sheds light on how seemingly unharmful actions like nose-picking might contribute to its development.

The nose-picking and Alzheimer’s connection

A recent report suggests that nose-picking could increase the risk of Alzheimer’s disease. This revelation stems from the discovery of a protein called beta-amyloid, known to be a significant factor in Alzheimer’s progression. Researchers propose that pathogens introduced through nose-picking may trigger the production of beta-amyloid in the brain, contributing to neuroinflammation associated with Alzheimer’s.
The report highlights the role of the olfactory system as a potential gateway for pathogens to enter the brain. Pathogens, including viruses, fungi, and bacteria, can establish persistent infections in nasal tissues, eventually reaching the brain and triggering neurodegenerative processes. This direct connection underscores the importance of maintaining nasal hygiene to mitigate the risk of Alzheimer’s.

Implications for Alzheimer’s prevention

Alzheimer’s prevention often focuses on lifestyle factors, and nose-picking may now be considered among them. While the habit might offer temporary relief, it’s crucial to prioritise proper nasal hygiene. Suggestions include gentle methods like saline rinses or blowing the nose to maintain cleanliness and reduce the risk of pathogen entry into the brain.
Further research is needed to solidify the link between nose-picking and Alzheimer’s risk in humans. Studies in mice have shown promising results, demonstrating how bacteria entering the brain through the olfactory nerve can lead to amyloid beta deposition. Human studies are underway to explore these findings and determine potential preventive measures against Alzheimer’s.
The association between nose-picking and Alzheimer’s risk underscores the complexity of dementia and the importance of exploring various contributing factors. While more research is needed to fully understand this connection, the findings emphasize the significance of maintaining nasal hygiene for brain health. As we unravel the mysteries of Alzheimer’s disease, addressing seemingly minor habits like nose-picking could play a role in prevention strategies.
