A new blood test can tell doctors whether a person has suffered a concussion up to a week after he or she was injured. 

一种新型的血液检查可以帮助医生分辨出病人在受伤的一周以内有没有得上脑震荡。

A study describing the test was published in the journal2 JAMA Neurology.

一篇关于该种血液检查的论文在《美国医学会神经学期刊》上发表了。

People who suffer a head injury should rest soon after they are hurt.Doctors say rest is important in helping3 the brain to heal4 after the injury.

遭遇头部损伤的人应该在受伤后马上休息。医生说这对大脑修复很有帮助。

Individuals who have suffered a concussion do not always show symptoms.Experts say those warning signs can be delayed, especially in children.

脑震荡的发生并不总是伴随症状。专家说，这样的警示信号总是被忽略，尤其是在孩子们身上。

A concussion can lead to a feeling of dizziness, headaches and an inability to sleep.These problems can exist for a long time.

脑震荡可能会引起头晕、头痛和失眠。这些问题会持续很长时间。

Some concussion patients have experienced5 loss of memory, trouble thinking and feelings of anxiety.

一些脑震荡的患者经历过记忆或思考困难以及焦虑。

Doctors at Orlando Health System in Florida developed the new blood test.It shows if a biomarker is present in a person’s blood.

佛罗里达州奥兰多卫生系统的医生开发出了这种新型的血液检查。它检查的是病人的血液中有没有一种生物标志物。

The biomarker is called glial fibrillary acidic protein, or GFAP.The protein is only found in the brain and nervous system after a person suffers a concussion.

这种生物标志物的名字叫作神经胶质纤维酸性蛋白，简称GFAP。该物质只会在脑震荡之后的大脑和神经系统中出现。

Researchers examined the blood of 600 patients.They found the biomarker in the blood of those who had suffered a head injury.

研究人员检测了600名患者的血液。他们在曾经有过头部损伤的患者血液中检出了该物质。

Concussion is a common injury in contact sports.A blood test soon after a head injury could show if an athlete has suffered a concussion.Without the test, sports team officials may not know whether the player has a concussion and may return him or her to the game.

脑震荡是一种在有身体接触的运动项目中常有的损伤。头部受伤之后立刻进行血检，就能看出运动员有没有得脑震荡。如果不做这个检测，运动队的领队们就没法知道某人有脑震荡，进而让他/她回去接着比赛。
