Overview=
Decerebrate and decorticate posturing can indicate that brain herniation is occurring[1] or is about to occur. Brain herniation is an extremely dangerous condition in which parts of the brain are pushed past hard structures within the skull. In herniation syndrome, which is indicative of brain herniation, decorticate posturing occurs, and, if the condition is left untreated, develops into decerebrate posturing.[1]
Causes
Posturing has also been displayed by patients with Creutzfeldt-Jakob disease.[2]
Decerebrate posturing can occur with diffuse cerebral hypoxia.[3]
Brain abscesses may also cause decorticate posturing.
In Children
In children younger than age 2, posturing is not a reliable finding because their nervous systems are not yet developed.[4] However, Reye's syndrome and traumatic brain injury can both cause decorticate posturing in children.[4]
For reasons that are poorly understood, but which may be related to high intracranial pressure, children with malaria frequently exhibit decorticate, decerebrate, and opisthotonic posturing.[5]
