Common Causes for Brain Injury

A brain injury is any injury to the brain that affects a person physically, emotionally or behaviorally. Brain injuries can happen at birth or may arise later from trauma or an illness. Depending on the cause, a brain injury is called either traumatic or non-traumatic.

Causes for Traumatic Brain Injury

Traumatic brain injuries do not always include an open head wound or skull fracture. Loss of consciousness may not occur either. These are the most common causes for a traumatic brain injury (TBI): 

  • Motor vehicle accidents 
  • Falls 
  • Violence or gunshot wound 
  • Military attack or bomb blast

Causes for Non-Traumatic Brain Injury

A non-traumatic brain injury may also be called an acquired brain injury or ABI. This type of brain injury is a result of an illness or condition within the body, and it is not a result of a blow to the head. These are the most common causes of a non-traumatic brain injury:

  • Stroke (leading cause)
  • Lack of oxygen (hypoxia)
  • Tumors
  • Other illness such as cancer
  • Brain infections or inflammation
