" According to the National Institute for Neurological Disorders and Stroke people in PVS "have lost their thinking abilities and awareness of their surroundings, but retain non-cognitive function and normal sleep patterns. Even though those in a persistent vegetative state lose their higher brain functions, other key functions such as breathing and circulation remain relatively intact. Spontaneous movements may occur, and the eyes may open in response to external stimuli. They may even occasionally grimace, cry, or laugh.... People suffering from PVS can generally be distinguished from afflicted but cognitively intact patients who suffer from "locked-in syndrome" by the fact that "locked in" patients can track visual stimuli and use eye blinks for communication.


Terri Schiavo's parents have posted several short ambiguous video clips online which are meant to show that Ms. Schiavo responds to stimuli. But what they show seems to fit an AMA's report of how PVS patients can respond to environmental cues without being aware. Specifically, the report notes, "Despite an 'alert demeanor', observation and examination repeatedly fail to demonstrate coherent speech, comprehension of the words of examiners or attendants, or any capacity to initiate or make consistently purposeful movements. Movements are largely confined to reflex withdrawals or posturing in response to noxious or other external stimuli. Since neither visual nor auditory signals require cortical integrity to stimulate brief orienting reflexes, some vegetative patients may turn the head or dart the eyes toward a noise or moving objects. However, PVS patients neither fixate upon nor consistently follow moving objects with the eyes, nor do they show other than startle responses to loud stimuli. They blink when air movements stimulate the cornea but not in the presence of visual threats per se."

Ms. Schiavo has been in this state for 13 years. What are her chances of recovering at least some awareness? Minnesota neurologist Ronald Cranford told the Washington Post, "There has never been a documented case of someone recovering after having been in a persistent vegetative state for more than 3 months."



I think that says it all...
