Smoking raises the risk of Alzheimer's disease by 40% — data from a meta-analysis of 2.8 million people
Scientists at Curtin University in Australia analyzed data from 61 studies involving about 2.8 million people. Smokers had a 31% higher risk of dementia, 52% higher risk of vascular dementia, and 40% higher risk of Alzheimer's disease. In former smokers, the risk returned to the level of those who had never smoked.
