<unk>  can result from severe central nervous system damage (brain injury, cervical or high thoracic spinal cord). In simple terms, the trauma causes a sudden loss of background SNS stimulation to the blood vessels. This causes them to relax (vasodilation) resulting in a sudden decrease in blood pressure (secondary to a decrease in peripheral vascular resistance).<unk>  results from damage to the spinal cord above the level of the 6th thoracic vertebra. It is found in about half of people who suffer spinal cord injury within the first 24 hours, and usually persists for one to three weeks.<unk>  may be caused by severe brain injury. However, in case of increased intracranial pressure, according to the Cushing triad, blood pressure will be increased (unless decreased from hypovolemia), respirations will be irregular and bradycardia will also be a feature.
