New research has revealed that the risk of dementia heightens if the individual is passive smoking, it has been revealed.
Scientists at the University of Cambridge discovered the link and released their findings today, displaying a common bond which highlights another potential danger which could bring about young onset dementia.
The saliva of 5,000 non-smokers was tested for cotinine, a chemical which is a by-product of nicotine.
Higher levels were linked to a 44 per cent increased chance of getting dementia.
Dr David Llewellyn, who wrote the report, stated: "Given that passive smoking is also linked to other serious health problems such as heart disease and stroke, smokers should avoid lighting up near non-smokers.
"Our findings also support calls to ban smoking in public places."
According to the Alzheimer's Society, there are 700,000 people with dementia in the UK.
