Coma is not a disease per se but instead an acute state of disordered consciousness clinically manifested due to a wide variety of medical and surgical disease processes that affect the central nervous system (CNS). It is usually described as "a state of unarousable unresponsiveness in which the eyes remain continuously closed and there is no understandable response to environmental or intrinsic stimulation."1 In contrast to the sleep state, during coma a person cannot be aroused by appropriate intense stimuli, there is no evidence of sleep–wake cycles on the electroencephalogram (EEG), and the behavioral responses mostly consist of reflex activity.
