New dementia research has been conducted, with extremely interesting and thought-provoking results.
In investigations carried out in Canada, it was revealed that air pollution seems to be quite closely linked to dementia. The study included research of almost 2 million people and of those, the people who lived within 50 meters of a main road had higher rates of diagnosis of the condition.
The rate of dementia declined, the further away from a main road the residents lived.
Although more extensive and concrete evidence needs to be carried out before coming to any real conclusion, it is an interesting addition to the debate. Dr Davis Reynolds. Chief scientific officer at Alzheimer’s Research UK commented that “Studies like this are valuable in revealing new factors that could be implicated in Alzheimer’s disease and other dementia's, and opening new avenues for further research. This study has identified major roads and air pollutants from traffic as possible risk factors for dementia, a finding which will need further investigation before any firm conclusions can be drawn.”
