What term describes the complication resulting from spinal cord injury above T6 that involves paroxysmal hypertension?

Autonomic hyperreflexia is the correct term for the complication that arises from a spinal cord injury at or above the T6 level, characterized by episodes of severe hypertension often accompanied by bradycardia. This condition occurs due to an imbalance in the autonomic nervous system, specifically when the sympathetic nervous system becomes hyperactive in response to a noxious stimulus below the level of the lesion, while the ability to modulate this response is impaired due to the spinal injury.

In patients with such spinal cord injuries, sensory input from below the injury site cannot be appropriately interpreted, leading to unregulated sympathetic responses. This can cause vasoconstriction and a spike in blood pressure, triggering a reflex response from the baroreceptors in the aortic arch and carotid sinus, which normally would help decrease blood pressure by increasing parasympathetic activity. However, the responses are dysregulated due to the injury, resulting in episodes of dangerously high blood pressure.

Understanding this condition is crucial for clinical practice, as it highlights the need for careful monitoring and management of blood pressure in patients with spinal cord injuries, especially those with injuries above the T6 level. This knowledge can aid in preventing serious complications associated with autonomic hyperreflexia, such as stroke or
