Final answer:
Nonaccidental trauma refers to intentional injuries, distinguishing it from accidental injuries, genetic disorders, or neurological conditions not related to inflicted harm.
Step-by-step explanation:
Nonaccidental trauma is a term that refers specifically to intentional injuries rather than accidental ones. It is not used to describe genetic disorders or neurological conditions unrelated to an inflicted injury. Trauma to the central nervous system can lead to serious outcomes such as traumatic brain injury (TBI), which occurs after a physical blow to the brain and involves both an acute phase and a possible secondary excitotoxic phase. Nonaccidental trauma is generally recognized in a medical and legal context as resulting from abuse or violence, and it is distinct from accidental causes of injury like falls, car accidents, or sports injuries.
