A brain injury is any injury occurring in the brain of a living organism. Forms and severity of brain injuries can greatly vary, but when any sypmotoms of a brain injury appear it should be immediately adddressed.
Specific forms of brain injury include:
- Brain damage, the destruction or degeneration of brain cells.
- Traumatic brain injury, damage that occurs when an outside force traumatically injures the brain, like a concussion.
- Stroke, a vascular event causing damage in the brain.
- Acquired brain injury, damage to the brain that occurs after birth, regardless of whether it is traumatic or nontraumatic, or whether due to an outside or internal cause.
Mild traumatic brain injury (mTBI) is one of the most common neurologic disorders. Persistent symptoms following mTBI might occur in 5% to 10% of patients and can include posttraumatic headache, sleep disturbance, disorders of balance, cognitive impairments, fatigue, and mood disorders. Persistent post concussive symptoms can result in functional disability, stress, and time away from work or school. These guidelines address the fact that to date, other than for sport concussion, little information and direction has been available to physicians to manage recovery from mTBI.
