Mild Traumatic Brain Injury.
It may seem strange to call a Traumatic Brain Injury (TMI) "mild." However, the use of the word "mild" is merely to help categorize TBI patients in an effort to better evaluate and treat them in contrast to those with "moderate" or "severe" TBI. Mild TBI's are the most common. The following is a helpful description of "mild" TBI.
A patient with mild traumatic brain injury is a person who has had a traumatically induced physiological disruption of brain function, as manifested by a least one of the following:1. any period of loss of consciousness;
2. any loss of memory for events immediately before or after the accident;
3. any alteration in mental state at the time of the accident (eg, feeling dazed, disoriented, or confused); and
4. focal neurological deficit(s) that may or may not be transient; but where the severity of the injury does not exceed the following:
- posttraumatic amnesia (PTA) not greater than 24 hours.
- after 30 minutes, an initial Glasgow Coma Scale (GCS) of 13-15; and
- loss of consciousness of approximately 30 minutes or less;
