New blood test might help aid concussion diagnosis


Diagnosing a concussion can be rather difficult for medical professionals. This is because some concussions don’t produce symptoms for hours, days, or weeks after the initial injury occurs. Often, patients are told to just keep an eye out for symptoms if they seek medical care right after the accident. A new blood test might change the way a concussion is diagnosed, which would be a positive change.

As it stands now, the time that passes between the brain injury and the diagnosis of a concussion can often mean that the patient suffers from negative effects that can have lasting impacts. The new blood test holds the possibility of reducing the risk of those lasting impacts because the concussion might be able to help doctors diagnose a concussion within days after the injury occurs.

Interestingly, current technologies can only help doctors to find large bleeds and large lesions through imaging methods. The new blood test, which was studied on 600 patients from March 2010 until March 2014 looked for glial fibrillary acidic protein, which changes over time after a brain injury.

In the study, the level of GFAP were the highest 20 hours after the injury occurred. Over the following seven days, this protein was still found in the blood at a reduced rate. This could be a huge improvement in the way that concussions are diagnosed and treated.

If you have suffered a concussion because of an accident that wasn’t your fault, you might choose to seek compensation. Learning about the methods you can use to seek compensation can help you to make a plan that you can follow as you move through the process.
