Great risk of Alzheimer’s and dementia occurring later in life is reported by men who smoke for years, according to new South Korean scientific research. Researchers, headed by Shang Min Park at the National University of Seoul, who published the journal Annals of Clinical and Translational Neurology, analyzed data on 46,140 men over the age of 60.
It was found, that in relation to smokers, non-smokers (who had never smoked in their lives) had an average 19% less risk of dementia, whereas for those who had cut off cigarettes for years, the risk of dementia was reduced by 14%.
Those who had never smoked had an 18% lower risk of Alzheimer’s than chronic smokers and 29% less risk of vascular dementia. Those who had been smokers but had quit smoking for a long time had a reduced risk of 32% of dementia.
“Stopping smoking is clearly associated with a reduced risk of dementia over time, so smokers have every reason to cut it off to benefit,” Parks said.
