A scientific review involving about 2.8 million people found that smoking is associated with an increased risk of dementia, Alzheimer's disease and vascular dementia, with the risk rising as the number of cigarettes smoked per day increases.According to the study, which was led by researchers from Curtin University in Australia and published in the journal "eClinicalMedicine", smokers face a 31% higher risk of developing dementia compared with people who have never smoked.The risk rose to 40% for Alzheimer's disease and to 52% for vascular dementia.The researchers observed a link between the number of cigarettes smoked per day and the likelihood of developing dementia. People who smoke 10 cigarettes a day face a 16% higher risk, while the risk rises to 34% among those who smoke 20 cigarettes a day, compared with people who have never smoked.Lead researcher Mario Serfo said the findings show the need to pay attention to the impact of smoking on brain health, alongside its well-known risks to the heart and lungs and the likelihood of developing cancer.He added that the relationship between smoking and dementia becomes stronger as the number of cigarettes consumed increases.Quitting smoking may reduce the risk of developing the diseaseThe study showed that people who had quit smoking do not face a higher risk of developing dementia compared with those who have never…
