As the news has been full of stories about several former NFL stars who have suffered traumatic brain injuries, some Pennsylvanians may wonder exactly what they are. A traumatic brain injury can occur when a person suffers a sudden trauma, such as when the head is hit by an object or when an object pierces the skull and enters the brain.
Traumatic brain injuries range in severity level. People who experience a mild TBI may remain conscious, or if they lose consciousness, the loss will only be for a few minutes. They may complain of tiredness, dizziness, blurred vision, ringing in the ears, having a bad taste in their mouths or being fatigued. A mild TBI may also result in a change in sleep patterns, memory problems, difficulty concentrating and behavior changes.
