Autonomic Dysreflexia is the name given to a condition where there is a sudden and potentially lethal rise in blood pressure (BP). It is your body’s way of responding to a problem. It is often triggered by acute pain or some other harmful stimulus within the body. It is unique to spinal cord injury and most commonly affects spinal cord injured people with injuries at or above T6. This extreme rise in blood pressure (hypertension) can lead to some types of stroke (cerebral haemorrhage) and even death.
