Which phrase describes traumatic brain injury (TBI)?

• A. Damage to the brain from an external mechanical force.
• B. Injury to the brain from an internal force.
• C. Degeneration of brain tissue due to aging.
• D. Inflammation of brain tissue due to infection.

Answer: (A)

Traumatic brain injury is defined by damage to the brain caused by an external mechanical force, such as a blow, fall, car crash, or blast. This external origin is what sets TBI apart from injuries caused by internal processes or non-mechanical factors. The other descriptions refer to aging-related degeneration or brain infections, which are not traumatic brain injuries. So, the phrase that best describes TBI is damage to the brain from an external mechanical force.
