a state of shock similar to others (for example, spinal shock, q.v.) in its ability to lead to inadequate perfusion. It is caused by interruption of vasomotor tone by injury to the autonomic nervous system. Often differentiated in clinical presentation, where the classic signs of tachycardia and cutaneous diaphoresis (that is, cool clammy skin) are absent.
neurogenic shockSpinal shock, see there.
neu·ro·gen·ic shock(nūr'ō-jen'ik shok)
A rare, usually transitory shock caused by decreased sympathetic control of blood vessel tone due to a defect in the vasomotor center in the brainstem or the sympathetic outflow to the blood vessels; may be due to brain injury, depressant action of drugs, general anesthesia, hypoxia, or hypoglycemia (e.g., insulin shock).
