Quitting smoking could offer a major benefit beyond heart and lung health, study finds
New research indicates that quitting smoking may significantly reduce the risk of developing dementia later in life. A study involving over 32,000 adults over 25 years found that former smokers had a lower risk compared to current smokers. The risk continued to decline the longer individuals remained smoke-free, approaching that of never-smokers after about seven years.
