Hyperreflexia

Autonomic hyperreflexia is a reaction of the autonomic (involuntary) nervous system to overstimulation.

Autonomic hyperreflexia is an abnormal triggering of the autonomic nervous system. It occurs after a spinal cord injury. The body is unable to turn off the nerves that cause blood pressure to rise.
