Global warming intensifies stroke risk: Study links temperature swings to rising stroke burden worldwide.

In a recent study published in the journal Neurology, researchers assessed the global burden of stroke attributable to non-optimal temperatures due to climate change.

Stroke is prevalent in older people and may be accompanied by severe sequelae and complications. In 2019, there were 12.2 million cases of incident stroke and 6.55 million related deaths, and it ranked third among the causes of disability-adjusted life years (DALYs). Studies have highlighted increased stroke burden with extreme temperatures. While the relationship between stroke and non-optimal temperatures has been explored, there is limited information about stroke burden and distribution across countries/territories.
