Blood Test Shows Concussion Injury
A new blood test can tell doctors whether a person has suffered a concussion up to a week after he or she was injured.
A study describing the test was published in the journal JAMA Neurology.
People who suffer a head injury should rest soon after they are hurt. Doctors say rest is important in helping the brain to heal after the injury.
Individuals who have suffered a concussion do not always show symptoms. Experts say those warning signs can be delayed, especially in children.
A concussion can lead to a feeling of dizziness, headaches and an inability to sleep. These problems can exist for a long time.
Some concussion patients have experienced loss of memory, trouble thinking and feelings of anxiety.
Doctors at Orlando Health System in Florida developed the new blood test. It shows if a biomarker is present in a person's blood.
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.
Researchers examined the blood of 600 patients. They found the biomarker in the blood of those who had suffered a head injury.
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 could return him or her to the game.

患者头部受伤后应该立刻休息 。医生表示，休息有助于受伤头部的愈合 。
脑震荡患者的症状有时不会表现出来 。专家称，尤其是儿童患者的症状会推迟 。
脑震荡会导致患者头晕、头痛以及无法入睡 。这些问题会长期困扰患者 。
佛罗里达州奥兰多医学中心的医生发现了这种新型血液检测 。它能检测出患者血液中是否存在某种生物标记 。
这种生物标记被称为“神经胶质纤维酸性蛋白” 。这种蛋白质只存在于脑震荡患者的脑部和神经系统中 。
研究人员检测了600名患者的血液 。在头部遭受过损伤患者的血液中发现了这种生物标记 。
脑震荡是一种常见的运动损伤 。头部受伤的运动员可通过血液检测出是否患上脑震荡 。如果没有这种测试，教练可能会在不知道运动员可能患脑震荡的情况下，重新派他上场参赛 。
