In USA, May is the "National Stroke Awareness Month", highlighting the need for increasing public awareness of stroke. While prevalent in developed countries, stroke is not uncommon in the developing world.

The map shows the global variation in stroke burden (2003) and the prevalence of hypertension in 2008. Uncontrolled hypertension is one important risk factor for stroke. Prevention and proper management of hypertension are therefore crucial in reducing the impacts of stroke on individuals and society. As depicted by graduated colours, eastern Europe, north Asia and central Africa are losing the highest number of life years as a result of stroke. Its association with high prevalence of hypertension, indicated by coloured arrows, is most significant in eastern Europe. The prevalence of hypertension and stroke burden is in fact lower in affluent countries, for example, in western Europe. Insufficient attention to stroke prevention and suboptimal access to effective health care in developing countries have contributed to the observed phenomenon.

Data for the map were obtained from World Health Organization.

五月是美國的 「全國腦中風關注月」,其間透過宣傳鼓勵民眾多認識中風。事實上,中風不單影響如美國等已發展國家,發展中國家亦面對同樣的問題。

高血壓是引致中風的重要高危因素之一,預防和控制高血壓有助紓緩中風對個人和社會的影響。地圖顯示全球各國2008年的中風嚴重性及高血壓流行情況,反映兩者息息相關。依圖中顏色所示,東歐、北亞及中非等地的人民因中風損失最多生命年(life years) 。箭咀圖案標示各國高血壓的流行程度,當中的東西歐國家之間的對比至為明顯。較富庶的西歐國民患高血壓的比率較東歐國民低,而因中風而損失的生命年亦比相對少。在發展中國家,由於醫療系統的局限和預防意識不足,以致國民因中風而影響健康的嚴重性較高。
