Autonomic dysreflexia is a syndrome in which there is a sudden onset of excessively high blood pressure. It is more common in people with spinal cord injuries that involve the thoracic nerves of the spine or above (T6 or above).
How does spinal cord injury affect blood pressure?
Signals from the brain send messages through the spinal cord to constrict blood vessels and raise the heart rate to keep the blood pressure and heart rate normal. When these signals cannot get through, a person can have low blood pressure and slow heart rate.
Does spinal injury increase blood pressure?
Autonomic dysreflexia is a serious medical problem that can happen if you’ve injured your spinal cord in your upper back. It makes your blood pressure dangerously high and, coupled with very low heartbeats, can lead to a stroke, seizure, or cardiac arrest.
Why does blood pressure drop in spinal cord injury?
A spinal cord injury can disrupt the reflexes that make blood vessels constrict and relax. When blood vessels relax too much, there isn’t enough force to keep blood flowing efficiently, which causes low blood pressure.
Can spinal compression cause hypertension?
Myelopathy from cervical cord compression may induce hypertension and sympathetic hyperactivity. Anesthesia may suppress sympathetic activity and lead to hypotension that require vasopressor treatment.
Does a spinal cord injury shorten your life?
Life expectancy depends on the severity of the injury, where on the spine the injury occurs and age. Life expectancy after injury ranges from 1.5 years for a ventilator-dependent patient older than 60 to 52.6 years for a 20-year-old patient with preserved motor function.
What does Dysreflexia mean?
Topic Overview. Autonomic dysreflexia is a syndrome in which there is a sudden onset of excessively high blood pressure. It is more common in people with spinal cord injuries that involve the thoracic nerves of the spine or above (T6 or above).
Does spondylosis cause high blood pressure?
Cervical spondylosis may be one of the causes of secondary hypertension. Early treatment for resolution of symptoms of cervical spondylosis may have a beneficial impact on cardiovascular disease risk in patients with cervical spondylosis.
Can spondylitis increase blood pressure?
Chronic neck pain is one of the major symptoms in patients with cervical spondylosis, whereas some studies have indicated that resting blood pressure levels may be elevated in patients with persistent pain. In healthy individuals, elevated blood pressure is associated with diminished acute pain sensitivity.
Do paraplegics have lower blood pressure?
THE resting blood pressure (B.P.) in tetraplegic patients is known to be low. Some paraplegics (including tetraplegics) have pathologically high B.P.; this hypertension often develops many years after the onset of the paraplegia and may be associated with renal complications.

How can I lower my blood pressure in minutes?
If your blood pressure is elevated and you want to see an immediate change, lie down and take deep breaths. This is how you lower your blood pressure within minutes, helping to slow your heart rate and decrease your blood pressure. When you feel stress, hormones are released that constrict your blood vessels.
