Stroke cases rising globally, air pollution, heat driving numbers: Lance

Incidence of stroke and related deaths are rising substantially around the world, with air pollution, high temperatures and metabolic risk factors such as high blood pressure and physical inactivity, driving these increases, according to estimates published in The Lancet Neurology journal.

Researchers found that the contribution of high temperatures to poor health and early death due to stroke has increased 72 per cent since 1990 and is likely to continue increasing in the future, thereby highlighting how environmental factors can impact growing stroke burden.

Further, for the first time, particulate matter or PM air pollution was found to have the same contribution as smoking towards causing a fatal form of brain bleed, according to the researchers forming the Global Burden of Disease, Injuries, and Risk Factors Study (GBD) group.

The GBD study, the "largest and most comprehensive effort to quantify health loss across places and over time", is coordinated by the Institute for Healt
