According to the U.S. Centers for Disease Control and Prevention (CDC), approximately 1.7 million people suffer a traumatic brain injury (TBI) each year. TBIs can be caused by any blow, bump, or jolt to the head that disrupts normal brain function. The degree of injury can range from mild, which involves a brief change in mental status or consciousness, to severe, which involves an extended period of unconsciousness or amnesia after the injury.
While the majority of traumatic brain injuries are mild, the effects of a severe TBI can be life-changing. A TBI can cause a wide variety of changes to a person's brain. These can include changes to:
- Cognition: memory and reasoning skills
- Sensation: the ability to touch, taste, and smell
- Language: both the ability to communicate and to understand what others say
- Emotion: TBIs have been linked to increased aggression, as well as disorders such as depression and anxiety
