Traumatic Brain Injury (TBI) refers to an injury to the head sustained from a blow or the person being shaken violently, causing the brain to slam against the walls of the skull.
This injury can change how the person acts, moves, and thinks. A traumatic brain injury can also change how a student learns and acts in school. The term TBI is used for head injuries that can cause changes in one or more areas, such as:
- thinking and reasoning
- understanding words
- remembering things
- paying attention
- solving problems
- thinking abstractly
- walking and other physical activities
- seeing and/or hearing
Studies now suggest that traumatic brain injuries can lead to early onset dementia. Symptoms can start up to years after the injury.
