Smoking Linked to Damage in the Brain, Researchers Find
Smoking may damage part of the brain by causing thinning in a crucial area, new research shows.
The study included more than 500 male and female smokers, former smokers and nonsmokers who were an average of 73 years old.
Brain scans revealed that current and former smokers had a thinner cortex than those who never smoked. The cortex is where important thought processes such as memory, language and perception occur.
