A new study has found that finger-picking may be linked to Alzheimer’s disease.
In a letter recently published in the American Journal of Medical Sciences, researchers say that putting a finger in the nose may be one of the main risks of contracting the disease.
Recent research has shown that germs transferred from the fingers to the nose can reach the brain and cause inflammation. This inflammation can damage brain cells over time and contribute to Alzheimer’s disease.
The report also found that finger-picking can also damage the nasal lining, allowing harmful microorganisms to easily enter the bloodstream and further inflammation, which can increase the risk of dementia. .
The published letter cites 10 studies (including a 2022 National Institutes of Health (NIH)-funded study) of a possible link between nose picking and Alzheimer’s. Reference evidence was found.
