Traumatic Brain Injury (TBI) - Levels of Severity. Mild TBI. Loss of consciousness is very brief, usually a few seconds or minutes. Loss of consciousness does not have to occur - the person may be dazed or confused. Testing and scans of the brain may appear normal. Most common: 75%-85% of all brain injuries are mild.
There are different types of brain injuries. Each type of brain injury is unique. The differences in brain injuries depend on the type of applied force, the amount of force, and on where on the head the force was received. The brain injury can affect just one functional area of the brain, several areas of the brain or the entirety of the brain. Sometimes I will use the term herein as âmild brain injuryâ. Please do not be misled.
