A 2-year follow-up study of cigarette smoking and risk of dementia.

Cigarette smokers may be more prone to suffer from dementia than non-smokers.

​This study investigated the link between cigarette smoking and the odds of developing dementia. Researchers surveyed 2,820 men and women above the age of 59 years for a period of 2 years. During the course of the study, a total of 121 participants were diagnosed with dementia. 

Researchers found out that cigarette smoking increased the risk of having dementia. The data from this study support the notion that cigarette smokers may be more liable to suffer from dementia.
