Stroke is among the world primary causes of adult disability and mortality. The World Health Organization (WHO) estimates that 15 million peopleworldwide have a stroke annually, of whom 5 million die and another 5 million become permanently incapacitated. Over 12.7 million strokes occur globally as a result of elevated blood pressure. Between 1990 and 2010, the number of strokes fell by around 10% in industrialized countries and climbed by 10% in developing countries. Every year, around 800,000 individuals in the US suffer from strokes, which claim the lives of over 140,000 people. Similarly, in Europe, strokes claim the lives of about 650,000 people. Smoking and bad lifestyle choices are contributing to the rising prevalence of stroke in emerging nations.
Approximately 32,000 brain cells are destroyed in a stroke in less than a second, 15% of sufferers pass away within a month, and 50% of survivors suffer from physical disabilities.
Stroke prevalence in India ranges from 84–262/100,000 in rural regions to 334–424/100,000 in urban areas. There is a significant range in the incidence of stroke in India, ranging from 147-922/100,000 in several community-based studies.
