Researchers analyzed data from 21,123 members of a health care system who participated in a behavior survey between 1978 and 1985. The survey recorded the incidence and the frequency of smoking.
These individuals were followed for 30 years and data on the diagnosis of dementia, Alzheimer’s disease or vascular dementia were collected.
Researchers then performed statistical analysis to identify the relationship between smoking and risk of dementia, Alzheimer’s disease and vascular disease.
Compared with non-smokers, those smoking more than 2 packs a day were 2 times more likely to develop Alzheimer’s disease, vascular disease and dementia.
If you like to enjoy your retirement with your memory intact, you should avoid smoking or consider quitting smoking when you are young.
