A 2019 Lancet Commission on dementia prevention ranked smoking as third among nine modifiable risk factors for dementia.
A recent review of 37 research studies found that compared to never smokers, current smokers were 30 percent more likely to develop dementia in general and 40 percent more likely to develop Alzheimer’s disease.
There is strong evidence that smoking can increase your risk of developing dementia, said the Alzheimer’s Society.

The health charity added: “Some reasons behind this include the fact that the two most common forms of dementia, Alzheimer’s disease and vascular dementia, have both been linked to problems with the vascular system (your heart and blood vessels).
“It is known that smoking increases the risk of vascular problems, including via strokes or smaller bleeds in the brain, which are also risk factors for dementia.”
