The NHS Choices “Behind the Headlines” service has released a further critical appraisal concerning an investigation into smoking-related health risks and dementia.
The cohort study in question investigated the possible relationship between environmental tobacco smoke (ETS) and the later risks of developing dementia syndromes. It concluded that ETS may be considered an important risk factor for severe dementia syndromes and that the avoidance of ETS could reduce the prevalence of severe dementia syndromes. Individuals in this study of 5,921 Chinese people who reported previous exposure to secondhand smoke had a 29% increased risk of developing a severe dementia syndrome compared to individuals with no such passive smoking exposure.
