<unk>  deaths per million persons in 2012 Disability-adjusted life year for cerebral vascular disease per 100,000 inhabitants in 2004.<unk>  was the second most frequent cause of death worldwide in 2011, accounting for 6.2 million deaths (~11% of the total). Approximately 17 million people had a<unk>  in 2010 and 33 million people have previously had a<unk>  and were<unk> ill alive. Between 1990 and 2010 the number of<unk> s decreased by approximately 10% in the developed world and increased by 10% in the developing world. Overall, two-thirds of<unk> s occurred in those over 65 years old. South Asians are at particularly high risk of<unk> , accounting for 40% of global<unk>  deaths. Incidence of ischemic<unk>  is ten times more frequent than haemorrhagic<unk> . It is ranked after heart disease and before cancer. In the United<unk> ates<unk>  is a leading cause of disability, and recently declined from the third leading to the fourth leading cause of death. Geographic disparities in<unk>  incidence have been observed, including the existence of a<unk>  belt" in the southeastern United<unk> ates, but causes of these disparities have not been explained. The risk of<unk>  increases exponentially from 30 years of age, and the cause varies by age. Advanced age is one of the most significant<unk>  risk factors. 95% of<unk> s occur in people age 45 and older, and two-thirds of<unk> s occur in those over the age of 65. A person's risk of dying if he or she does have a<unk>  also increases with age. However,<unk>  can occur at any age, including in childhood. Family members may have a genetic tendency for<unk>  or share a lifestyle that contributes to<unk> . Higher levels of Von Willebrand factor are more common amongst people who have had ischemic<unk>  for the first time. The results of this<unk> udy found that the only significant genetic factor was the person's blood type. Having had a<unk>  in the past greatly increases one's risk of future<unk> s. Men are 25% more likely to suffer<unk> s than women, yet 60% of deaths from<unk>  occur in women. Since women live longer, they are older on average when they have their<unk> s and thus more often killed. Some risk factors for<unk>  apply only to women. Primary among these are pregnancy, childbirth, menopause, and the treatment thereof (HRT).
