Smokers are 45% more likely to develop dementia
Smokers have a 45% higher risk of developing dementia than non-smokers, experts have said.
And the more a person smokes, the higher the risk, according to a new report from World Health Organization (WHO) in collaboration with Alzheimer's Disease International.
Even passive smoking could increase the risk, the publication states.
It also highlights that 14% of Alzheimer's disease cases are potentially attributable to smoking, the authors said.
Dr Shekhar Saxena, director of the Department for Mental Health and Substance Abuse at the WHO, said: "Since there is currently no cure for dementia, public health interventions need to focus on prevention by changing modifiable risk factors like smoking.
"This research shows that a decrease in smoking now is likely to result in a substantial decrease in the burden of dementia in the years to come."
Serge Gauthier, chair of Alzheimer's Disease International's medical scientific advisory panel, welcomed the findings.
