Second-hand smoke increases dementia risk

Worried about how your brain will work when you are older?  Then avoid being around people who smoke. 

Second-hand smoke can cause the neurological disease of dementia on top of causing breast cancer, heart diseases and respiratory illness.

The University study on more than 6,000 participants reveals that some 10% of people with severe dementia were associated with the same level of cigarette smoke exposure as well as the duration of second-hand smoking.

“Avoiding exposure to tobacco smoke may reduce the risk of severe dementia syndromes.  Passive smoking should be considered an important risk factor for dementia syndromes.  The increased risk of severe dementia syndromes in those exposed to passive smoking is similar to increased risk of coronary heart disease” 
Study leader Dr Ruoling Chen, King’s College, London.

Study on more than 6,000 participants aged over 60 living in five Chinese provinces was conducted by the researchers from Anhui Medical University in China and King’s College London, and published in Occupational and Environmental Medicine, January 2013.  The scientists assessed dementia syndromes and measured their exposure to second-hand smoke during 2001-2003 and 2007-2008.  As reported by on Sunday January 13, 2013.
