Evaluation of disturbances of consciousness.

Consciousness as the highest form of neuronal activity is very difficult to define. It is superior to unconditioned reflex activity and vigilance, and its most important sign is verbal signalization. Therefore, a scheme of evaluation of impaired consciousness was elaborated by the author, in which in the first group a strong painful impulse is the stimulus, in the second group of consciousness proper the word is the stimulus. This simple scheme of 8 points can be applied also by nurses.
