What is a medical emergency associated with spinal cord injuries at or above T6?

Autonomic Dysreflexia is a critical medical emergency that can occur in individuals who have suffered spinal cord injuries at or above the T6 level. This condition arises due to the disruption of autonomic nervous system regulation, leading to an exaggerated response to stimuli that would typically not cause a significant effect in a person with intact spinal function.

In practical terms, autonomic dysreflexia occurs when noxious stimuli—such as bladder distension, bowel impaction, or skin irritation—trigger an overactive sympathetic response below the level of injury. This leads to symptoms such as severe hypertension, bradycardia, profuse sweating, and flushing above the level of the injury. If left untreated, this condition can lead to life-threatening complications such as stroke or cardiac arrest, making immediate recognition and treatment essential.

Understanding this condition highlights the importance of regular health assessments in individuals with high spinal cord injuries to prevent potential triggers and manage any symptoms promptly. The other conditions listed are relevant to spinal cord injuries but do not represent the same level of acute risk as autonomic dysreflexia.
