National Brain Injury Awareness Month


A traumatic brain injury, or TBI, is an injury that affects how the brain works. It may be caused by a:

  • Bump, blow, or jolt to the head, or
  • Penetrating injury

There are three (3) main types of TBI:

  • Mild traumatic brain injury or concussion
  • Moderate TBI
  • Severe TBI

People most commonly get TBIs from a fall, firearm-related injury, motor vehicle crash, or an assault
Research shows that:

  • Falls lead to nearly half of the TBI-related hospitalizations
  • Firearm-related suicide is the most common cause of TBI-related deaths in the United States5,
  • Motor vehicle crashes and assaults are other common ways a person may get a TBI
