Arousal and response to external influences: Awakening is the state of being able to open the eyes naturally or open the eyes when there is an external stimulus . Responses are directed actions of the body in response to stimuli.

Reception and perception: The ability to acquire and understand language, to receive perceptual stimuli such as sounds, images, etc., and sensory stimuli such as heat, cold, pain, and sensations. essence. Consciousness is governed by the cerebral hemispheres, so the normal state of consciousness depends on the integrity of the two cerebral hemispheres.
Mechanism of action of the brain on consciousness: When the body receives a stimulus or a signal, these signals are transmitted to the brain, then the brain will analyze and transmit signals in response to the stimuli. prefer. There are many signals to the brain.

Disturbance of consciousness is a condition in which the patient has reduced or lost the ability to orient in space, time, himself and his surroundings.

Gloomy syndrome: The patient has a mild disturbance of consciousness, still able to distinguish space and time, distinguishing between time and space. self. But the response to the stimulus is slow, when asked, it is bewildered to understand slowly, there is still memory. Somnolence syndrome: The orientation in space, time and self is not clear, the reflex ability is poor, only responding to strong stimuli. Memory decline. Semi-coma syndrome: Complete loss of orientation, very strong stimulation to feel, reduced autonomic reflexes. Coma syndrome: Complete loss of orientation, unresponsiveness, loss of reflexes.

Evaluation of eyes:
Natural opening: 4 points Response to opening eyes when ordered: 3 points Response to opening eyes when causing pain: 2 points Do not open eyes: 1 point

Verbal assessment:
Correct answer: 5 points Confused answer: 4 points Incorrect answer: 3 points Confused speech: 2 points No answer: 1 point Motor assessment:
True acting on demand (on command): 6 points Correct response to stimulus: 5 Points Frictional response to pain: 4 points Loss of cortical contracture when causing pain: 3 points Instrumental extensor posture when causing pain : 2 points No response to pain: 1 point The highest total score is 15 and the lowest is 3. Assess the degree of consciousness disorder according to the following points:
Normal consciousness: 15 points Mild cognitive disorder : 9-14 points Severe disturbance of consciousness: 6-8 points Deep coma: 4-5 points Very deep coma: 3 points
