Air pollution and stroke - Stroke Association comments

A study published in the BMJ suggests that air pollution is associated with a higher risk of stroke, particularly in developing countries.

Common stroke risk factors include smoking and high blood pressure. But the effect of the environment, such as, air pollution is uncertain because evidence is lacking.

Dr Shamim Quadir, Research Communications Manager at the Stroke Association, said: “This study suggests that air pollution is a possible trigger for stroke. It is well established that air pollution can have serious implications for our health. However,this study does not establish a biological link between stroke and short-term exposure to air pollution. 

“More in-depth investigation is needed to establish whether or not air pollution can be considered as a risk factor for stroke. Anyone with any concerns about their stroke risk should speak with their GP.”
