What signifies a non-traumatic brain injury?

A non-traumatic brain injury refers to damage to the brain that occurs without an external impact or force. This type of injury is often caused by internal factors, such as a stroke, infection, or a lack of oxygen to the brain, rather than from physical trauma. The essence of non-traumatic injuries lies in the fact that they arise from internal processes or conditions affecting brain function, rather than from an external event impacting the head.

The other options represent types of injuries that are consistently linked with an external force or trauma. For instance, injuries caused by an object hitting the head, falls, or fractures during sports are all examples of traumatic injuries, where there is a clear external source of damage. In contrast, the correct concept emphasizes injuries that stem from internal physiological changes or medical conditions, highlighting the distinction between traumatic and non-traumatic brain injuries.
