Passive smoking increases risk of severe dementia, according to study in China
An international study by scientists in China, the UK and USA has found a link between passive smoking and syndromes of dementia.
The study of nearly 6,000 people in five provinces in China reveals that people exposed to passive smoking have a significantly increased risk of severe dementia syndromes.
Passive smoking, also known as ‘second-hand’ smoke or environmental tobacco smoke (ETS), is known to cause serious cardiovascular and respiratory diseases, including coronary heart disease and lung cancer. However, until now it has been uncertain whether ETS increases the risk of dementia, mainly due to lack of research. Previous studies have shown an association between ETS and cognitive impairment, but this is the first to find a significant link with dementia syndromes.
