Autonomic Dysreflexia

Autonomic dysreflexia is an acute syndrome characterized by abrupt onset of excessively high blood pressure caused by uncontrolled sympathetic nervous system discharge in patients with spinal cord injury (SCI). Au-tonomic dysreflexia is potentially life-threatening.

The syndrome was first described by Head and Rid-doch in 1917 (Head and Riddoch 1917). In 1947, Gutt-mann and Whitteridge showed the effects of bladder distensions on the cardiovascular system (Guttmann and Whitteridge 1947). Autonomic dysreflexia is also known as autonomic hyperreflexia, paroxysmal neuro-genic hypertension, sympathetic hyperreflexia, and neurovegetative syndrome.
