Try living away from traffic to protect yourself from dementia

Researchers have found that living near traffic is associated with an increased risk for dementia.

Living near a lot of traffic can create a lot of tension and raises fears of an increased risk for pulmonary diseases including lung cancer due to the pollution. Living near a lot of traffic has also been found to be associated with an increased risk for dementia.

There may be an increased risk of dementia by as much as 7 percent from living near a highway

According to research published in the Lancet, there may be an increased risk of dementia by as much as 7 percent from living near a highway. This study was done on greater than six million people in Canada.

Via tracking these people the researchers observed that over a period of 11 years there was a clear association between developing dementia and living near a major road. People who live within 50 meters of traffic which is heavy had a 7 percent increased risk of getting dementia in comparison to people whose homes were greater than 300 meters away from a primary busy road.

Hong Chen, the leader of the study who works at Public Health Ontario, says the findings show that there is an increased risk of getting dementia if you live closer to roads which have heavy daily traffic. There are serious public health implications associated with this finding due to the widespread exposure which we have to traffic and the increased tendency for people to reside in cities in this era.

Long-term exposure nitrogen dioxide and fine particulates has an association with dementia

It was also determined in this study that the long-term exposure nitrogen dioxide and fine particulates, which are two common components found in air pollution, has an association with dementia. Air pollution has also been associated with dementia in other studies. However it is likely there are also other factors which are involved.

This study has been published in The Lancet. A new study has found an association exists between living near major roads with traffic and the incidence of dementia. In view of the emerging evidence which suggests that living near major roads might have an adverse affect on cognition it would seem wise to live in places with clean air which are as far away from roads with a lot of traffic as possible.
