A new study suggests that quitting smoking may significantly reduce the risk of developing dementia later in life. Researchers at a Chinese university analyzed data from over 32,000 adults over a 25-year period, documenting 5,868 cases of dementia. The findings, published in the journal Neurology, indicate that former smokers had a lower risk of dementia compared to current smokers. Participants who quit during the study period showed a risk similar to those who had never smoked, with benefits increasing the longer they remained smoke-free. The strongest benefits were observed among those who gained little or no weight after quitting. Lead researcher Hui Chen emphasized that quitting smoking supports long-term brain health, but post-quitting habits also play a role. Zaid Fadul, a Harvard-trained physician, noted that smoking cessation can protect brain health by reducing inflammation, oxidative stress, and vascular damage linked to cognitive decline.
