How do I know if a brain injury is mild, moderate or severe?

There are three different levels of brain injury - mild, moderate and severe - each has different causes and subsequent symptoms. An assessment, called the Glascow Coma Scale (GCS) is used to determine the level of injury.

Mild Traumatic Brain Injury (TBI)

  • Sometimes a loss of consciousness occurs, but does not have to occur to be considered a TBI.
  • Brain scans may appear normal.
  • If a concussion occurs, the person's brain functioning may be altered.

 Symptoms include:

  • Headaches
  • Difficulty remembering things
  • Balance problems
  • Irritability
  • Problems with concentration
  • Nausea
  • Emotional problems including, anxiety, depression and mood swings

Moderate Traumatic Brain Injury (TBI)

  • Can include confusion, loss of consciousness and behavioral problems.
  • Person can usually make a positive recovery.

Severe Traumatic Brain Injury (TBI)

  • Severe trauma includes prolonged periods of unconsciousness.
  • Can include a coma or vegetative state. 

The Brain Injury Association of America provides a wealth of information on the degrees of severity and the subsequent symptoms as well as rehabilitation. The type and amount of force inflicted will all affect the determination of whether a brain injury is mild, moderate or severe.If you have been involved in an accident and injured due to someone else's negligence, call an experienced St. Louis Accident Attorney.  Call Alvin Wolff at 314-241-2500
