In brief: Sympathetic discharg

After a traumatic brain injury (tbi), particularly a severe one, there can be a loss of sympathetic regulation.
The sympathetic nervous system can be uncontrolled and there is a discharge of hormones that can lead to symptoms that include hypertension and tachycardia. This can be very severe and discomforting.
