Mild TBI's are defined as loss of consciousness and/or confusion and disorientation for less than 30 minutes while severe TBI's are defined as loss of consciousness for more than 30 minutes and memory loss after the injury or penetrating skull injury for longer than 24 hours. TBI's can result in permanent brain damage as a full recovery is not guaranteed and largely depends on the severity of the brain injury, the nature of the injury, and the treatment received among other factors. Brain injuries can also be caused by subconcussive head impacts or hits to the head that don’t cause full-blown concussions.įurthermore, brain injuries can be caused by other health issues like strokes, bleeding in the brain, lack of oxygen to the brain, brain infections, fluid buildup in the brain, toxic exposure and poisoning, and brain tumors. Any injury to the brain is a real and serious medical condition.īrain injuries are caused by concussions and other traumatic head forces that cause damage to the brain (e.g., car accident, gunshot wound to the head, assaults, falls). Keep in mind that there is nothing “Mild” about a brain injury-the term “Mild” Brain injury is used to describe a level of neurological injury. There may be no correlation between the initial Glasgow Coma Scale score and the initial level of brain injury and a person’s short or long term recovery, or functional abilities.
Severe Traumatic Brain Injury (GCS of below 8) Moderate Traumatic Brain Injury (GCS of 8-12) Mild Traumatic Brain Injury (GCS of 13-15) The terms Mild Brain Injury, Moderate Brain Injury, and Severe Brain Injury are used to describe the level of initial injury in relation to the neurological severity caused to the brain. Source: Centers for Disease Control and Injury PreventionĮmergency personnel typically determine the severity of a brain injury by using an assessment called the Glasgow Coma Scale (GCS). The number of people with TBI who are not seen in an emergency department or who receive no care is unknown.
According to the Centers for Disease and Control Injury Prevention Center, the leading causes of traumatic brain injury are:īrain injury can result in a range of outcomes:
