Disorders of Consciousness

Disorders of consciousness (pronunciation: /dɪsˈɔːdəz ɒv ˈkɒnʃəsnɪs/) are a set of conditions that disturb a person's ability to be awake, aware, or both. These disorders can be caused by a variety of factors, including brain injury, disease, medication, or surgery. They are characterized by significant changes in a person's ability to interact with the environment and others.

Etymology

The term "disorders of consciousness" is derived from the Latin words "dis" meaning "apart" and "ordo" meaning "order", and the Latin word "conscientia" meaning "knowledge". Thus, it refers to conditions that disrupt the normal order of consciousness or awareness.

Types of Disorders of Consciousness

There are several types of disorders of consciousness, including:

  • Coma: A state of unconsciousness where the person is unresponsive and cannot be woken.
  • Vegetative state: A condition where the person is awake but not aware.
  • Minimally conscious state: A condition where the person has minimal but definite awareness of self or environment.
  • Locked-in syndrome: A condition where the person is aware and awake but cannot move or communicate due to complete paralysis of nearly all voluntary muscles.
