male and female communication essay

In some cases, a patient has been able to communicate transiently for the first time after a 20-minute stimulation—by, for example, making a simple movement in response to a question. patient does not make attempt to avoid noxious stimuli! There … As a physician, it is my aim to translate this knowledge into practice. These findings may have implications for the assessment of the reorganization of REM sleep during recovery from vegetative state and may further help in our understanding of the pathophysiology of vegetative state. MEASUREMENTS AND RESULTS: Sleep-related erection episodes (SREe's) were noted in all nine patients, ranging in number from 1-7/24 hr (average 4.4+2.4) and lasting 6 to 50 min (average 22.0+5.7 min). The longest duration of coma was seen in patient M.M. When we dream, our brains are filled with noisy electrical activity that looks nearly identical to that of the awake brain. CONCLUSIONS: The sleep-related erection characteristics of patients in vegetative state are similar to those of normal individuals. Coma is a state in which a person is unconscious for a long time, completely unresponsive to the outside stimuli, like sounds and pain. patient lies still (when not stimulated). This form of communication doesn’t generally work, and our team was wrongly connected with it. The number of REM … Lehembre R, Gosseries O, Lugo Z, Jedidi Z, Chatelle C, Sadzot B et al (2012) Electrophysiological investigations of brain function in coma, vegetative and minimally conscious patients. If the results show that there is no hope whatsoever, we then discuss difficult topics with the family, such as end-of-life options. "Anesthesia can have some side effects. The purpose of this article is to provide a brief overview of EEG patterns for comas with various causes, and indicate how EEG can contribute to an assessment of the prognosis for coma patients. Then you will know that, if you are ever in that position, your desires and values will be taken into account. But EEGs alone can not tell whether a patient is awake or dreaming: Doctors can only distinguish REM sleep by recording rapid eye movement -- hence, the name -- and muscle tone, since our bodies relax in a general paralysis to prevent us from acting out our dreams. From that point on, we can ask the patient pertinent questions. Although his phone rings constantly, he takes the time to talk to me about the fine points of what consciousness is and how to identify it in patients who seem to lack it. We are still faced with the question of the minimum acceptable quality of life. Steven Laureys greets me with a smile as I enter his office overlooking the hills of Liège. Discover new insights into neuroscience, human behavior and mental health with Scientific American Mind. I wish Shared dreaming could be less complicated and more diversed, because then If someone is in a coma then someone else could just hack into that person dreams and help them awaken. If a teenager is in a coma, will body growth occur as if he or she were not in the coma? One well-known case was that of Rom Houben. Knowledge of the anatomical basis of coma is essential for competent evaluation but must be combined with an understanding of the many, often multi-factorial, medical conditions that result in impaired consciousness. Doctors and researchers believe there are subtle signs that a person is trying to wake up. As I neared his suite, my feet picked up their pace. As a neurologist, I see the consequences of brain damage every day. If the motor cortex is activated, we know that the patient heard and understood and therefore is conscious. During sleep, we are more or less responsive to our surroundings, depending on the sleep stage. In the minimally conscious state, patients show preserved arousal level and exhibit discernible but fluctuating signs of awareness. He suffered a stroke that left him with locked-in syndrome. A friend of mine is writing a novel and is doing research for certain details within the story. So how is it possible to study something as complex as consciousness? Details about how the affected person lost consciousness, including whether it occurred suddenly or over time 3. The person is alive, but they cannot respond in the normal way to their environment. in contrast to the drug-induced atonia described above, rigidity and spasticity are typically seen in patients who are in a coma or a vegetative state, and muscle tone is preserved during slow-wave sleep. We have also found that it is possible to examine a person’s pupils: we ask patients to multiply 23 by 17 if they intend to say yes. The goal was to determine the structure of sleep within the two types of patient. The physician says, “Squeeze my hand.” Or we observe whether the patient responds to sounds or touch. To hear, we need not only ears and the auditory cortex but also this external network, which probably exists in each hemisphere of the brain—in the outermost layer of the prefrontal cortex as well as farther back, in the parietal-temporal lobes. A comatose patient may grimace, move limbs, and have stereotypical withdrawal responses to painful stimuli yet make no localizing responses or discrete defensive movements. Coma-like sleep is characterized by a deep sleep devoid of movement. In my opinion, this represents the future of treatment, even though we do not yet know precisely which regions of the brain are the most responsive to stimulation or whether they should be stimulated on a daily basis. In rare cases, the patient may be in a coma exclusively as a result of this. It is a complex case that the media has failed to report adequately. Only one (16.67%) patient was UWS, which belongs to the non-conscious group. The longer a patient remains in a coma the poorer his or her chance of recovery and the greater the chance that he or she will enter a vegetative state (table 3). The first step was to get him fully out-of-coma and the second to make him speak and communicate again. This difficult problem causes the patients to concentrate, and their pupils will dilate slightly as a result. He wrote an entire book—on which the movie was based—by blinking his one remaining functional eye. The term DoC includes patients in coma, VS/UWS and MCS. That’s right.
