Half a packet a day raises dementia risk

Published tisdag 26 oktober 2010 kl 13.26
This is the biggest such study so far

Not only will smokers live shorter lives, they are also more likely to suffer from dementia in their old age, says a major new study.

Researchers in Sweden, Finland and the USA tracked 20,000 people aged 50-60. Twenty years later over one in four of them had dementia, due to smoke blocking the blood flow in their veins.

Miia Kivipelto, at Sweden's Karolinska Institute, says that half a packet a day is enough to increase the risk of dementia, and that "those that smoked two packets a day had their risk doubled compared to non-smokers."

It also indicates that those who give up smoking can escape the raised risk of dementia.

Miia Kivipelto also says that people should remember that smoking is just one of the risk factors for dementia.
