Which statement describes an indirect traumatic brain injury?

• A. Direct impact to the head
• B. Force was applied to another body part, but the brain was still affected
• C. Penetrating head wound
• D. Skull fracture without brain injury

Answer: (B)

Indirect traumatic brain injury occurs when the brain is injured by forces transmitted to it from trauma to another part of the body or from a mechanism that causes the head and brain to accelerate, decelerate, or rotate—injury happens without a direct blow to the brain itself. The statement describes a force applied to a different part of the body, yet the brain is still affected, which fits this idea of an indirect mechanism. The brain is injured not because something directly hit the head, but because the movement or jarring of the head transmits forces to the brain inside the skull. Direct impact to the head would cause injury from the object striking the head itself. A penetrating head wound involves an object entering the skull and brain. A skull fracture without brain injury describes a scenario where the skull is damaged but the brain remains unharmed, which does not describe an indirect brain injury.
