A traumatic brain injury (TBI) differs from brain injuries caused by disease or a degenerative condition in that it specifically results from trauma of some sort. Any trauma to the head, such as a collision, blow to the head, or penetration of the skull by a foreign object, can result in brain injury. In moderate cases, brain injury may result in symptoms including:
- Ringing in the ears
- Mood changes
- Problems with memory
- Inability to concentrate
In severe cases, traumatic brain injury can drastically impact a person's mental capacity, leaving him or her unable to maintain an independent lifestyle, care for him or herself, and maintain employment. Sadly, the mental impact often leaves the victim in a state that is unrecognizable from his or her former self.
