The clinical features include following simple commands, manipulation of objects, gestural or verbal yes/no responses, intelligible verbalization, and stereotypical movements. Locked-in syndrome describes an individual who has the content of thought and the level of arousal intact.

A person experiences edema in the brain caused by movement of CSF from the ventricles into the extracellular space. What type of edema does this describe? A. Vasogenic B. Cytotoxic C. Ischemic D. Interstitial

D. Interstitial edema is caused by transependymal movement of CSF from the ventricles into the extracellular spaces of the brain tissues. Vasogenic edema is caused by the increased permeability of the capillary endothelium. Cytotoxic edema occurs when toxic factors cause active transport systems to fail.
