Document Summary

Distinguish among disorders of consciousness, and how brain imaging can help to differentiate these. Locking-in phase: condition in which an individual is fully conscious, but all the voluntary muscles of the body are completely paralyzed, with the possible exception of the muscles controlling eye movement. Vegetative state: describes a person who is awake and shows sleep-wake cycles but shows no signs of being aware of himself or his environment. He is unable to interact with others and shows no evidence of reproducible voluntary responses to any kind of external stimulus. signs of sleep cycles, opens her eyes, and makes some noise, although there is no connection to outside stimuli. Coma: a state of extreme unresponsiveness in which an individual exhibits no voluntary movement or discernible sleep-wake cycles. Brain death: irreversible unconsciousness with complete loss of brain function. Permanent vegetative state: after the vegetative state the brain could either moves towards recovery or could remain in the vegetative state forever.
