A brain injury is any injury occurring in the brain of a living organism. Brain injuries can be classified along several dimensions. Primary and secondary brain injury are ways to classify the injury processes that occur in brain injury, while focal and diffuse brain injury are ways to classify the extent or location of injury in the brain. 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.
- 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.
Famous quotes containing the words brain and/or injury:
“I think taste is a social concept and not an artistic one. Im willing to show good taste, if I can, in somebody elses living room, but our reading life is too short for a writer to be in any way polite. Since his words enter into anothers brain in silence and intimacy, he should be as honest and explicit as we are with ourselves.”
—John Updike (b. 1932)
“Every act of conscious learning requires the willingness to suffer an injury to ones self-esteem. That is why young children, before they are aware of their own self-importance, learn so easily; and why older persons, especially if vain or important, cannot learn at all.”
—Thomas Szasz (b. 1920)
