Autonomic Dysreflexia (AD), also known as Hyperreflexia, is a potentially dangerous complication of spinal cord injury (SCI). In AD, an individual's blood pressure may rise to dangerous levels and if not treated can lead to stroke and possibly death. Individuals with SCI at the T-6 level or above are at greater risk. AD usually occurs because of a noxious (irritating) stimulus below the level of the injury. Symptoms include headache, facial flush, perspiration, and a stuffy nose. AD occurs primarily because of an imbalance in the body systems which control the blood pressure. The human body is an incredibly complicated and beautifully balanced machine. There are balances to each system of the body, including the blood pressure. One of the major ways the body controls blood pressure is by tightening or relaxing little muscles around the blood vessels. When the muscles contract, the blood vessels get smaller and blood pressure increases. Imagine a garden hose with water streaming through it; when you put your thumb over the opening of the hose, reducing the opening for the water to flow through, the water shoots out at a higher pressure. Similarly, when the blood vessels are smaller, the blood rushes around your body at higher pressure.

Extractions: What is it? Pathophysiology Distention or contraction of the bladder or bowel, or stimulation of skin or pain receptors triggers a sympathetic response (from intact autonomic reflex arc) below the level of the lesion. The release of catecholamines causes vasoconstriction and hypertension. Hypertension stimulates baroreceptors in the carotid sinus, aorta and cerebral vessels. This causes the parasympathetic nervous system to be stimulated, which attempts to restore the BP back to normal. The heart rate decreases (vagal nerve), but inhibitory messages are unable to relax the blood vessels below the cord lesion. Vasoconstriction below the level of the cord injury causes the hypertension to persist.

Autonomic dysreflexia is a life-threatening condition that occurs in response to stimulation of internal organs (such as an expanded bladder) or of the skin, after the shock of a spinal injury has worn off. Specifically, patients with this autonomic dysreflexia have a spinal cord injury located near the middle of the spinal cord (an area known as T7) or above. T7 (Thoracic 7) refers to the 7th segment of the thoracic (chest) area of the spine. Autonomic dysreflexia is characterized by an impairment of the autonomic nervous system. If you already know all about the autonomic nervous system, then skip the next paragraph. If you don't know what the autonomic nervous system is, then the second paragraph was written just for you. WHAT IS THE AUTONOMIC NERVOUS SYSTEM? The autonomic nervous system is an extensive network in the body (with connections to the spinal cord) that is important for involuntary bodily functions that are necessary to maintain life, such as respiration (breathing) and heart rate. The autonomic nervous system consists of the sympathetic nervous system (the part that generally excites the body by doing things such as increasing both the heart rate and blood pressure), and the parasympathetic nervous system (the part that generally calms the body down by doing things such as decreasing both the heart rate and blood pressure). Thus, the sympathetic and parasympathetic nervous systems work in opposition to each other.

Extractions: Fact Sheet 25: Autonomic Dysreflexia Reader: Family, Professional Autonomic dysreflexia (or hyperreflexia) is a complication which occurs in people with spinal cord injuries at or above the level of T6 (or rarely as low as T8). In other words, it can occur in all quadriplegics and in paraplegics who have loss of sensation at or above the lower rib cage. It apparently does not occur in any condition other than spinal cord injury (SCI), therefore most physicians have never heard of it. For a detailed description of the neuropathology see one of the references in the bibliography. The first episode of dysreflexia usually occurs within four to six months after SCI, but may be as early as two months or as late as 10-12 years. Unfortunately, with the short hospital stays these days, many individuals will be discharged from the hospital before the first episode. Even if they were told about dysreflexia in the hospital, they may not remember what they were told and don't recognize the symptoms. How Often Does Dysreflexia Occur?

Extractions: Autonomic dysreflexia (sometimes called hyperreflexia) is unique to people with spinal cord injury above the T6 level and is a condition you should be aware of. It occurs when there is some stimulation below the level of your injury (see list below) that causes part of your nervous system to respond in an uncontrolled way. You will recognize autonomic dysreflexia by these symptoms.. Autonomic dysreflexia can be brought on by specific stimulation in areas below the level of injury. These may include: When autonomic dysreflexia occurs during sexual activity that activity should be stopped for a few minutes. Alternatively, another activity may be substituted. It is important that you try to find creative solutions instead of stopping all forms of sexual activity. If autonomic dysreflexia continues to be a problem or is interfering with your sexual life you may want to talk to your doctor about using a medication that you take just before sexual activity to prevent the dysreflexia from happening. During labour and delivery, contractions of the uterus can cause autonomic dysreflexia which can be mistaken for a condition called pre-eclampsia which some able-bodied women experience with pregnancy. The two are very different and are managed differently. With pre-eclampsia, the high blood pressure is continuous. With autonomic dysreflexia, the blood pressure and other symptoms are only present during the contractions. In between the contractions the blood pressure will go down. Your doctor will be aware of the need to carefully monitor your blood pressure when you are in labour. [See also Pregnancy, Labour and Delivery: link to consumer section on Preg,labour and delivery]
He4.html HEALTH. autonomic dysreflexia The nervous system consists of two separatesystems, the central nervous system and the autonomic nervous system. http://www.paraquad-nsw.asn.au/he4.html
Extractions: The nervous system consists of two separate systems, the central nervous system and the autonomic nervous system. The central nervous system is voluntary. This refers to the parts of the body where the brain can control what happens by sending and receiving messages. The autonomic nervous system is involuntary and refers to the processes in the body the brain does not control, its main function is to maintain a stable internal environment. The autonomic nervous system is divided into two systems. The parasympathetic and the sympathetic nervous system. Parasympathetic System Sympathetic System The parasympathetic system is the "slowing down" of the system. When the parasympathetic system is dominant: Blood vessels dilate Heart rate decreases Digestive movement increases Sphincters relax Bladder contracts Autonomic dysreflexia is caused by a variety of stimuli, creating an exaggerated response of the sympathetic nervous system (comprising the thoracolumbar outflow of the autonomic nervous system) due to lack of control from higher centres. This condition occurs mainly when the level of injury is at the T4-6 segmental levels or higher. When injury is sustained below this level, enough of the sympathetic nervous system is usually preserved to avoid this abnormal functional response (Zejdlik, 1992).

Extractions: What are the indicators for the onset of AD? 1. Hypertension (blood pressure greater than 200/100). Uncontrolled high blood pressure is the dangerous part of autonomic dysreflexia, for it may be high enough to cause a stroke. 2. Pounding headache 3. Flushed (reddened) face 4. Red blotches on the skin above level of spinal injury 5. Sweating above level of spinal injury 6. Nasal stuffiness 7. Nausea (secondary to vagal parasympathetic stimulation) 8. Bradycardia - slow pulse <60 beats per minute 9. Piloerection ("goose bumps") below level of spinal injury
