We used data from the oxford community stroke project ( ocsp ; 1981 ? 86 ) and the oxford vascular study ( oxvasc ; 2002 ? 06 ) to investigate changes in the incidence of intracerebral haemorrhage with time , above and below age 75 years , together with associated risk factors and premorbid medications 我们的资料来自牛津社区卒中研究计划（ ocsp ； 1981 ? 86 ）和牛津血管病研究（ oxvasc ； 2002 ? 06 ） ，使用这些资料来研究75岁上下的颅内出血的发病率，同时研究与之相关的风险因素和发病前的药物治疗。
There has been a substantial fall in hypertension - associated intracerebral haemorrhage over the past 25 years , but not in the overall number of cases of intracerebral haemorrhage in older age - groups , in part due to a rise in intracerebral haemorrhage associated with antithrombotic use 在过去25年，与高血压有相关性的颅内出血（发病率）大体上是下降的，但在高龄人群中，颅内出血的总体病例数（变化）并非如此，这在某种程度上是因为与（发病前）应用抗凝药物有关的颅内出血的发病率的增高。
