Traumatic Brain Injury (TBI)
A brain injury caused by an external force, including a blow or jolt to the head or object entering the brain, that results in cognitive, physical, and emotional impairments.
TBI is classified as either primary, meaning the damage is immediate, or secondary, meaning they can occur gradually over the course of hours, days, or weeks after injury. Some types of TBI can cause problems with brain function, including problems with how a person thinks, understands, moves, communicates, and acts and more serious TBI can lead to severe and permanent disability, and even death.
