A coma, sometimes also called persistent vegetative state, is a profound or deep state of unconsciousness. Persistent vegetative state is not brain-death. An individual in a state of coma is alive but unable to move or respond to his or her environment. Coma may occur as a complication of an underlying illness, or as a result of injuries, such as head trauma. Persistent vegetative state should not be diagnosed until 12 months from onset of coma [letter; comment].

Written by authors with over 20 years of experience in the rehabilitation of patients in a persistent vegetative state, this practical text bridges a gap in the specialized literature by providing neurologists, emergency physicians, physiatrists, and internists, as well as therapists, with a new set of tools to make rapid progress in the treatment of these patients whose improvement is wholly. Consciousness is a difficult term to define, and even more complicating is the fact that many different meanings and classification systems exist for the various states of decreased level of consciousness, such as drowsiness, stupor, and coma. For practical reasons, however, in the evaluation of consciousness most clinicians give greater weight to the patient's responses and behavior than to.

Adapted from Laureys et File Size: KB. Lancet, Jennett and Plum described the vegetative state as a “syndrome without a name.” In this paper, we tell the story behind that name, perhaps one of the most important in modern medicine, tracing an etymological lineage back to Aristotle. Jennett and Plum characterized the persistent vegetative state as a state of wakeful.

The state of wakeful unconsciousness -- the persistent vegetative state -- was described and labeled by Jennett and Plum in In this book, Jennett presents a comprehensive overview of the medical knowledge and legal history of the vegetative state over the past 30 Cited by: Persistent vegetative state describes the chronic condition that almost invariably emerges after coma.
It comprises a return of wakefulness (e.g. eye opening), sleep-wake cycles, and reflex movements (e.g. sucking, startle responses, grabbing), accompanied by a. A coma rarely lasts more than 2 to 4 weeks.
Some patients may regain a degree of awareness after persistent vegetative state. Others may remain in that state for years or even decades. The most common cause of death for someone in a persistent vegetative state is.
Coma, vegetative state, lock-in syndrome and akinetic mutism are defined.

Traditionally, a vegetative state that lasts > 1 month is considered to be a persistent vegetative state.
However, a diagnosis of persistent vegetative state does not imply permanent disability because in very rare cases (eg, after traumatic brain injury), patients can improve, reaching a minimally conscious state or a higher level of.
A coma is a profound or deep state of unconsciousness (consciousness being the awareness of the self and the environment). People in a state of coma are alive but unable to move or respond to their environment.

The study underscores the necessity of using standardized and objective diagnostic criteria in diagnosing coma. However, it also leaves some important questions unanswered. As background it is essential to understand a bit about.

As a result, patients in persistent vegetative states can. A vegetative state occurs when the cerebrum (the largest part of the brain) is severely damaged (making mental function impossible), but the reticular activating system is still functional (making wakefulness possible).
The reticular activating system controls whether a person is awake (wakefulness). It is a system of nerve cells and fibers located deep within the upper part of the brain stem. persistent vegetative state a condition of profound nonresponsiveness in the wakeful state caused by brain damage at whatever level and characterized by a nonfunctioning cerebral cortex, the absence of any discernible adaptive response to the external environment, akinesia, mutism, and inability to signal; the electroencephalogram may be isoelectric or show abnormal activity.
