Let’s dive a bit deeper and see what brain injury is all about.

About Traumatic Brain Injury (TBI)     

In a nutshell, brain injury will come about when there is violent blunt force trauma to the head, or an object penetrates the brain tissue such as a bullet. If you experience a mild traumatic injury, your brain cells will heal after a while. 

For severe traumatic injury, the results can be devastating, such as torn tissues, bruising, or bleeding, which can cause long-term complications or death.

The essential things to remember when someone experiences brain injury are:

  • Someone with a brain injury is a person first
  • Brain injuries are not exactly the same irrespective of their similarities
  • The effects of brain injury are dependent on location, cause, and severity
  • The effects of brain injury vary from person to person and are complex

Brain injuries can be classified in three ways depending on the mechanism and severity of the injury:

  • Mild: This is when you are awake, and the eyes are open
  • Moderate: This is when you are lethargic, and the eyes are open to stimulation. There a loss of consciousness that can last up to six hours
  • Severe: the person is unconscious, and the eyes do not open.
