This syndrome (disorder of consciousness) is almost beyond description. The easiest way to characterize it is with a negative attribute - “the ability to correctly evaluate the environment.”
Syndromes of impaired consciousness are the deepest degree of disorganization of mental activity. With them, there is a simultaneous violation of all mental functions, including the ability to navigate in place, time, and environment, and sometimes in one�s own personality. The main symptom of syndromes of impaired consciousness is the loss of communication between the patient and others.
They indicate a state of stupefaction. The main common symptom of syndromes of impaired consciousness is the loss of the patient�s connection with the outside world, expressed in the complete or almost complete impossibility of perceiving, understanding and remembering current events. During these states, thinking is disorganized, and after their end, the period of disturbed consciousness is completely or partially amnesic. Syndromes of impaired consciousness are rightfully compared with the physiological state, because in a dream, a person also temporarily loses contact with the outside world. It is known, however, that physiologically soybean is not a homogeneous state; two phases are clearly distinguished in it, changing repeatedly during the night. orthodox or slow-wave sleep, which occurs with signs of significant brain activity and is devoid of dreams, and paradoxical or REM sleep, which occurs with signs of significant brain activation and is accompanied by dreams. In a similar way, among the syndromes of impaired consciousness, two groups of conditions are distinguished.
Syndromes of switched off consciousness, in which mental activity is reduced to the extreme or completely stops. Syndromes of darkened consciousness, in which intense mental activity continues in the brain, isolated from the outside world, in a form largely reminiscent of dreams. Depending on the depth of the decrease in clarity of consciousness, the following stages of switched off consciousness are distinguished. obnubilation, doubtfulness, stupor, coma. In many cases, as the condition worsens, these stages successively replace each other. A carefree mood is often noted. Such conditions in some cases last minutes, in others, for example, in some initial forms of progressive paralysis or brain tumors, there are long periods.
