In recent years, the number of survivors of severe brain injuries has increased following improvements in intensive care, which go hand in hand with an increase in the number of patients diagnosed with a disorder of consciousness. We can distinguish two types of disorders of consciousness: “If repeated tests do not demonstrate a sustained, reproducible, intentional or voluntary behavioral response to visual, auditory, tactile or noxious stimuli, a diagnosis of vegetative state is made. Some patients remain permanently in a vegetative state. Others eventually show inconsistent, but reproducible signs of awareness, including the ability to follow commands, but remain unable to communicate interactively. This is called the minimally conscious state.” (Monti, et al. 2010, p.580) The number of misdiagnoses in disorders of consciousness is now set at a rate of approximately 40%. This was stated in the research “Willful Modulation of Brain Activity in Disorders of Consciousness” by Monti, et al. (2010) in the New England Journal of Medicine. The research was conducted with two main objectives: the first objective was to determine the percentage of patients who were able to repeatedly adjust their functional MRI responses with sound. The second objective was to develop and validate a technique that would allow these patients to communicate by answering yes or no questions using their own brain activity. The research involved a control group, 54 patients with impaired consciousness and functional magnetic resonance imaging (MRI). The control group included 16 healthy people with no history of neurological disorders and of the 54 patients, 23 were in a vegetative state and 31 in a minimal... half-paper state... practically only a consequence of the low sensitivity of the method. Finally, the cause of the disorder of all 5 patients who were able to voluntarily regulate their brain activity was head trauma. No further research was conducted for this strange feature and it was not even explicitly mentioned in the research. In conclusion, the flaws in the methodology were underdeveloped because the researchers did not consider conducting further research. The researchers were too optimistic about their results and did not pursue questions that arose after the results arrived. To effectively apply this technique, more research on the issue of head trauma is certainly needed. It may be that patients in a vegetative state due to head trauma have a better chance of recovery than other patients. At this moment I do not believe that this technique can be used to represent the mood of patients
