In 2014, the World Health Organization (WHO) published a report entitled “Tobacco Use & Dementia,”3, 4 based on a comprehensive scientific review of tobacco use, exposure to secondhand smoke, and incidence rates for all types of dementia, including Alzheimer’s.
The report found that smokers have a 45 percent higher risk of developing dementia than non-smokers, and concluded that 14 percent of all Alzheimer’s cases worldwide may potentially be attributed to smoking.
These risks hold true across nearly every income level and geographic boundary—including US, China, India, and Latin America. Smokers with dementia also die earlier than non-smokers with dementia.
