Answer

According to the World Health Organization (WHO), 15 million people suffer stroke worldwide each year. Of these, 5 million die and another 5 million are left permanently disabled. [25]

The global incidence of stroke has at least a modest variation from nation to nation, suggesting the importance of genetics and environmental factors, such as disparities in access to health care in developing countries. The age-adjusted incidence of total strokes per 1000 person-years for people 55 years or older has been reported in the range of 4.2 to 6.5. The highest incidences have been reported in Russia, Ukraine, and Japan.

In a prospective, population-based registry study from Italy, the crude annual incidence rate of intracerebral hemorrhage was 36.9 per 100,000 population. When standardized to the 2006 European population, the rate was 32.9 per 100,000 population; standardized to the world population, the rate was 15.9 per 100,000 population. [26]

Overall, the incidence of acute stroke has demonstrated a constant decline over the past several decades, most notably during the 1970s-1990s, although in recent years the rate trend has begun to plateau. However, the increased survival among stroke victims will place an increased demand on health-care systems globally. [8, 27]
