And that does come down to commonsense, in a way. You have to decide that. Because people in the vegetative state will respond to noise - by startle or jump, will respond to pain — by moving away, often will have some spontaneous movement, their eyes will move all over the place, they might yawn, sometimes they might stretch or they might move their arms.
The question of whether someone in the vegetative state can feel pain is interesting and difficult to answer. I personally believe that they are not aware of pain.
And of course we talk about it — we say they feel pain and withdraw. But they respond to it. Fern does not think her partner feels pain. From eyes watching and looking at another body, that body is suffering. So it might look like, every time he goes through these. The body is going through something, but he is not in that body, he does not feel it. He does not feel any of it. Fern describes how her partner did appear to be suffering before he was given ongoing long-term pain relief. Since he has been administered pain relief she has noticed that he appears more relaxed and not in pain.
He was on, as and when paracetamol [laughs]. And I can see it, because he just relaxes. That dystonic arm thing — he come down. The breathing, it regulates. And now the thing is, you can do the SATS level, and it still may be done at ninety, or eighty-nine or whatever.
The sweat, the panic, you know, we had him sat up and he was just not coping. He was puffing, he was puffing, he was gurgling.
The heart rate was shot up, do you know, it was uncomfortable. Fighting for oxygen, fighting to get stuff in. I mean that blood pressure, that heart rate is normal. David: No.
Olivia: It was her body. But I suppose bizarrely, maybe as a daughter-in-law, out of respect for my mother-in-law, you know, I would — I treated her as I would have done if she would have been— David: Well, yeah, yeah. For example, should we obtain informed consent directly from the patient rather than asking their legal guardian? Read More: Genome editing: Are we opening a back door to eugenics?
At the conceptual level, new models of consciousness are now being developed. One of these, called the Intrinsic Consciousness Theory , includes elements from both philosophy and neuroscience and describes consciousness as a continuum. With this model, it is difficult to draw a sharp definition between an unconscious mind and a conscious one.
This agrees with recent scientific evidence and a related theory of the unconscious, which emerges not as something passive, flat, and similar for everyone, but as an active and subjective brain dimension, which is to a certain degree, unique, because it results from previous life experiences. Moreover, the unconscious is not disconnected from awareness and it contributes massively to shape our aware life. Recent research shows that the unconscious is able to correlate information, associate meaning, reason quickly, develop complex computations, selectively focus on information, and to make complex inferences.
They can make decisions to act based on information gathered from their surroundings, and evaluate their experiences, and demonstrate goal-directed behavior.
While consciousness is usually defined as the opposite of unconscious, recent research suggests that this kind of interpretation is too simplistic and should be updated and the concept of unconscious emotion is increasingly gaining scientific literacy. Just because a patient shows no visible signs of consciousness does not mean that they are not conscious. And Jane should be treated and consulted in the same way as the conscious patient, by helping to alleviate pain and provide stimulation in the same way.
The ethical relevance of the unconscious Philosophy, Ethics, and Humanities in Medicine. DOI Michele Farisco. This practice should be changed, says researcher. Norwegian nurses keep diaries for their patients who are in comas.
Patients remain in this decreased body temperature for 24 h and then their bodies are rewarmed. Hopefully, patients can later awake from their comas and regain consciousness. It is important for medical doctors to have ways of knowing which coma patients are likely to awake.
In most hospitals, there are clinical tests to find out which coma patients are not doing well. But there are very few tests to predict when a patient will awake, and an accurate prediction is usually challenging. In our study, we aimed at developing a test that predicts whether a patient will awake from a coma. For this test, we studied the brain responses of coma patients to sounds [ 4 ].
Imagine, for example, a series of sounds coming from tapping your fingers repeatedly, or from playing a musical note on the piano. Imagine listening to the same note being played over and over again. You can also hear some of these sounds in Audio File 1. We presented these sounds to the patients and while we measured their brain activity with EEG. Our goal was to study how their brains reacted to the series of sounds. Different colors on the maps show that different brain regions were activated in response to sounds.
Brain functions can be different from one patient to another. For this reason, we computed a mathematical model to find patterns in brain responses to standard or deviant sounds Figure 1B. We repeated this analysis two times, in the first and second day of coma. The first time we measured, the body temperature of the patients was lowered. The second time, the temperature was back to normal [ 5 ]. All the patients we included in this study were fully unconscious.
Their bodies could not react to most of the things happening around them. What about their brains? Very interestingly, the brains of several patients reacted to the sounds that we played to them.
This ability to tell different sounds apart was almost as accurate as for healthy and awake people, at least for the first day of coma. In the second day, the ability to discriminate sounds was decreased for those patients who later died. This means that their brains could not easily tell whether a sound was standard or deviant. For each patient, we measured how much the ability of the brain to tell sounds apart changed, from the first to the second day of coma.
