  "account": "An Australian-led study of over 2 million people suggests current smokers have a higher risk of dementia, prompting calls to incorporate brain health into anti-smoking efforts. Led by Curtin University, the systematic review and meta-analysis of 61 studies found current smokers face a 31 percent increased risk of dementia, a 40 percent higher risk of Alzheimer's, and a 52 percent higher risk of vascular dementia compared to lifelong non-smokers. The research, published in eClinicalMedicine, also revealed the more cigarettes smoked daily, the greater the dementia risk - 16 percent higher for 10 cigarettes a day and 34 percent higher for 20. Former smokers did not show increased dementia risk compared to never-smokers, though the study cannot confirm smoking causation. Researchers urge inclusion of brain health in smoking cessation campaigns, warnings, and quit programs.",
