Smoking tobacco is the leading cause of preventable death, according to the U.S. Centers for Disease Control. Now there’s evidence of another negative side affect: thinning of the very important cortex regions of the brain.
This thinning was recently identified by an international team of researchers from the Montreal Neurological Institute at McGill University and the University of Edinburgh.
Cortex thinning is a part of aging, and smoking appears to accelerate that process. This thinning is believed to contribute to elderly cognitive decline.
