Altered mental status is a critical indicator that may suggest a cervical spine injury. When cervical spinal cord injury occurs, it can compromise neurological function and lead to a range of cognitive impairments, including confusion, disorientation, or decreased level of consciousness. This neurological impairment can stem from direct trauma to brain regions responsible for cognitive processing, as well as secondary effects such as hypoxia or hypoperfusion resulting from severe spinal injuries.

Significant cervical spine injuries can disrupt communication between the brain and the rest of the body, potentially resulting in altered sensorium. Therefore, if a patient presents with altered mental status following a mechanism of injury that may involve the cervical spine, further evaluation for spinal injury is warranted, including a thorough neurological examination and imaging studies, if necessary.

Other indicators like bradycardia and hyperreflexia can occur in the context of cervical spine injuries, particularly in the setting of autonomic dysfunction associated with spinal cord damage, but altered mental status directly reflects changes in brain function and is therefore more specifically indicative of a potential cervical spine injury. Normal reflexes would not suggest the presence of injury, as they would indicate that the spinal cord's neural pathways remain intact.
