One risk factor I often don’t think about when reviewing an acute stroke patient is head injury. However, a systematic review by Turner and colleagues in this month’s International Journal of Stroke (IJS),¹ which included a sample size of over 2.5 million participants, reports that individuals with traumatic brain injury have a significantly increased risk of stroke with a hazard ratio of 1.86. This risk appeared highest in the first four months post injury but remained significant for up to five years. The authors speculate on what the underlying mechanisms may be, and how this risk might be reduced. It is certainly an area meriting more research.

在检查急性中风患者时，我经常不会考虑的一个风险因素是头部受伤。然而，Turner 及其同事在本月的国际卒中杂志( IJS ) 上进行的一项系统性回顾，¹包括超过 250 万参与者的样本量，报告称患有创伤性脑损伤的人患中风的风险显着增加，具有风险比1.86。这种风险在受伤后的前四个月出现最高，但在长达五年的时间内仍然显着。作者推测潜在的机制可能是什么，以及如何降低这种风险。这当然是一个值得更多研究的领域。
