Which of the following is NOT considered primary damage in TBI?

• A. Contusions
• B. Seizures
• C. Lacerations
• D. Epidural hematoma

Answer: (B)

In traumatic brain injury, primary damage is the immediate mechanical injury to brain tissue and structures that occurs at the moment of impact. This includes contusions (bruising of brain tissue), lacerations (tears in brain tissue or vessels), and epidural hematoma (blood buildup between the skull and dura from a torn artery). These are the direct, structural injuries present right after the trauma.

Seizures, while common after TBI, are not considered primary damage. they arise from secondary processes that develop after the initial injury—such as ionic imbalances, excitotoxicity, edema, ischemia, and inflammation. Because they reflect evolving pathophysiology rather than the immediate mechanical injury, seizures are classified as a secondary complication rather than primary damage.

So the item that is not primary damage is seizures.
