Which of the following is NOT a sign of neurological trauma?

Euphonia refers to a pleasant sounding voice or the quality of being articulate and fluent in speech. In the context of neurological trauma, signs typically relate to impaired functions such as altered consciousness, changes in motor function, sensory deficits, or speech difficulties. While a person with neurological issues might exhibit difficulties in speech, such as dysarthria (slurred speech) or aphasia (loss of ability to communicate), having euphonia does not indicate a problem. Thus, euphonia itself is not a sign of neurological trauma.

On the other hand, excitement may indicate heightened emotional responses often associated with distress or traumatic experiences, shock can refer to the body's critical response to trauma (including neurological distress), and improper eyesight can directly relate to neurological deficits affecting vision pathways in the brain. These will all typically manifest as signs of possible neurological issues.
