Traumatic brain injury

A traumatic brain injury (TBI) can happen if your head is hit very hard or shaken violently. Brain damage from a head injury can change how a person acts, moves, and thinks. Damage can be mild to severe. People with TBI often have problems with:

  • Thinking and reasoning
  • Memory
  • Understanding words
  • Talking
  • Walking
  • Seeing, hearing, touching, tasting, or smelling

A person with a TBI may also show changes in behavior, such as:

  • Aggression
  • Acting out
  • Depression
  • Anxiety
  • Personality changes

Therapists design rehabilitation programs to help people with TBIs regain as much independence as possible. But the rehabilitation process is unique to the patient. For instance, some people with TBIs live in group homes to help them relearn skills needed to live and work independently. Other people with TBIs are able to live at home and go to day or outpatient rehab centers.
