Abnormal consciousness is caused by pathologies that specifically alter the function of a neuronal network responsible for causing awareness and alertness. Understanding of the basic concepts of this arousal system and the pathophysiologic mechanisms underlying its alteration are imperative in the diagnosis, treatment, and long-term management of coma. This chapter will focus on the definition of consciousness, the physiology of arousal, the pathologies underlying coma, the neurologic examination of the comatose patient, management of coma, and assessment of prognosis. Each section is accompanied by a case to illustrate the different clinical scenarios in which coma can present.

NCBI Bookshelf. Boston: Butterworths; The normal state of consciousness comprises either the state of wakefulness, awareness, or alertness in which most human beings function while not asleep or one of the recognized stages of normal sleep from which the person can be readily awakened. The abnormal state of consciousness is more difficult to define and characterize, as evidenced by the many terms applied to altered states of consciousness by various observers. Among such terms are: clouding of consciousness, confusional state, delirium, lethargy, obtundation, stupor, dementia, hypersomnia, vegetative state, akinetic mutism, locked-in syndrome, coma, and brain death. Many of these terms mean different things to different people, and may prove inaccurate when transmitting and recording information regarding the state of consciousness of a patient. Nevertheless, it is appropriate to define several of the terms as closely as possible.

What Is Consciousness?

Consciousness is the quality or state of being aware of an external object or something within oneself, such as thoughts, feelings, memories, or sensations. It has also been defined in the following ways: sentience, awareness, subjectivity, the ability to experience or to feel, wakefulness, having a sense of selfhood, and the executive-control system of the mind. At one time, consciousness was viewed with skepticism by many scientists, but in recent years, it has become a significant topic of research in psychology and neuroscience. Despite the difficulty in coming to a definition, many philosophers believe that there is a broadly shared underlying intuition about what consciousness is. Philosophers since the time of Descartes and Locke have struggled to comprehend the nature of consciousness and pin down its essential properties.

Consciousness refers to your individual awareness of your unique thoughts, memories, feelings, sensations, and environments. Essentially, your consciousness is your awareness of yourself and the world around you. This awareness is subjective and unique to you. If you can describe something you are experiencing in words, then it is part of your consciousness. Your conscious experiences are constantly shifting and changing. For example, in one moment you may be focused on reading this article.

However, there are also wakeful situations in which we can experience an altered state of consciousness ASC — these include hallucination, hypnotic states, trance states and meditation. The idea that bodies might be possessed by demons, witches, or spirits also exists as a popular theme in media and in some religious traditions.
