Define the term “secondary brain injury.”

The term "secondary brain injury" refers to the damage that occurs as a consequence of biochemical and cellular processes following an initial primary injury to the brain. This secondary damage can be caused by a range of factors, including inflammation, swelling, and disruptions to the brain's chemical environment. Such processes can lead to further cellular death, complications in blood flow, and even have long-term effects on neurological recovery.

Understanding secondary brain injury is crucial for effective treatment and management of brain injuries. Interventions that focus on minimizing secondary injury can significantly influence patient outcomes, making it imperative for medical professionals to take steps to mitigate these processes after the primary injury occurs.
