[Disturbances of consciousness of old people from internal view (author's transl)].

Abstract Any unconsciousness and especially that of old people refers to direct danger to life and requires immediate medical intervening. A diagnostic plan will not be adequate in association to the multifariour etiological factors and can delay in a special case the beginning of an aimed therapy. The unconscious patient must have a clinical treatment. The author describes the diagnostic of the most important comatose states in the age.
