What is a potential sign of serious issues following a TBI?

Double vision, also known as diplopia, can be a potential sign of serious complications following a traumatic brain injury (TBI). This symptom may indicate damage to the cranial nerves or other structures involved in vision processing, which could suggest the presence of more severe internal injuries.

When a person experiences a TBI, a variety of neurological symptoms can arise, and visual disturbances such as double vision should not be overlooked. This symptom could be accompanied by other signs of neurological compromise, which may require immediate medical attention.

The other options, while they may seem positive, do not accurately reflect potential serious issues following a TBI. Improved mood and better concentration can be misleading, as they might reflect temporary psychological responses rather than a true recovery from the injury. Reduced headaches could suggest improvement, but it does not indicate that the individual is out of danger. Therefore, double vision stands out as a critical sign that warrants further evaluation.
