I was hit by an 18-wheeler and diagnosed with, among other things, traumatic brain injury. Would I be able to file a lawsuit?

Before you file a traumatic brain injury, you first need to confirm your injury was caused by a trauma to the head. If you have sustained a serious jolt or blow to the head and you are experiencing some unusual symptoms, you should consult with a doctor about the possibility of having a traumatic brain injury. If it is confirmed by a physician that you do have traumatic brain injury and it was likely as a result of your accident, you should be able to file a lawsuit.

Some symptoms that may signal a traumatic brain injury may include, but not be limited to the following:

more forgetful about appointments, names, things you said and numbers
difficulty following the thread of conversations
difficulty remembering what a speaker said
difficulty understanding a movie plot
difficulty concentrating to read
forgetting what you read
getting lost easily
using different words than you think you used
difficulty learning new tasks, remembering familiar ones
