What is the specific name for primary and secondary brain injuries?

• A. Coup and Contrecoup
• B. Concussion
• C. Diffuse axonal injury
• D. Subdural hematoma

Answer: (A)

Coup and contrecoup describe injuries that happen at two sites from a single head impact: the brain injures at the point of contact (coup) and on the opposite side as the brain rebounds (contrecoup). This terminology captures the idea of damage occurring in two related locations from one traumatic event, reflecting how primary damage at the impact site can be followed by secondary injury on the opposite side due to inertia. Other options name a type or a pattern of injury (concussion as a mild TBI, diffuse axonal injury as widespread axonal damage, subdural hematoma as bleeding under the dura) rather than the paired localization produced by the impact. Thus, coup and contrecoup is the best fit for describing primary and secondary brain injuries in this context.
