Answer
Consciousness is the defining property of living organisms. The word coma comes from the greek word coma which means “deep sleep”. Coma is a state of unconsciousness in which a person cannot be awakened and fails to respond to any stimuli or perform any voluntary action. The person is still alive, but the brain is functioning at its lowest stage of alertness. The various causes of coma are severe injury to head, infection in brain, overdose of some medicine, stroke or some illness. A person in coma has brain dead but , they are living, as they require nourishment and maintenance Glassgow coma scale is a numerical system to estimate a patient’s level of consciousness. The higher the score, the greater the level of consciousness.
