Concussive nerve involvement
Introduction
Introduction Concussive nerve involvement is a condition in which a nerve undergoes an external force and a progressive neurological dysfunction that can be recovered within hours or weeks. Abnormal performance such as vomiting and headache can occur.
Cause
Cause
Clinically more common in concussion, spinal cord concussion. The cause of the disease is the pathological change of the original affected nerve due to the long time of ischemia. The root cause should have a history of head trauma, which is a very important primary cause.

Concussion (neurological surgery) refers to a transient brain dysfunction that occurs immediately after an external force is struck by the head. There is no significant change in pathological changes, and there is still much debate about the mechanism. The clinical manifestations were transient coma, near-forgotten and headache, nausea and vomiting. No positive signs were found in the neurological examination.
Spinal cord concussion is similar to concussion and is the mildest spinal cord injury. Immediately after the spinal cord suffered a strong shock, there was a slow sputum, and the sensation of the plane below the injury, the motor reflex and the sphincter function were all lost. Because no pathological changes occur in histomorphology, only temporary functional inhibition can be fully restored in minutes or hours.
Concussive nerve involvement combined with mild edema of the interstitial nerve leads to functional nerve damage. The clinical symptoms often have symptoms after nerve injury, but various imaging examinations are difficult to diagnose. Sometimes the EMG can reflect the nerve conduction velocity minus Slow, most of them can not detect neurological problems.
Diagnosis
Differential diagnosis
Differential diagnosis of concussive nerve involvement:
With shock nerve involvement, organic nerve damage, pathological nerve damage, hypoxic ischemic nerve damage, functional nerve injury, primary nerve injury, secondary nerve injury, delayed nerve injury, neurological spasm Isophase identification.
