Information About

Unconsciousness




Loss of consciousness should ''not'' be confused with the notion of the psychoanalytic Unconscious or cognitive processes (e.g., implicit cognition) that take place outside of awareness.

Loss of consciousness may occur as the result of Traumatic Brain Injury , brain Hypoxia (e.g., due to a brain Infarction or cardiac arrest), severe poisoning with drugs that depress the activity of the central nervous system (e.g., alcohol and other hypnotic or sedative drugs), and other causes.


LAW AND MEDICINE

In Jurisprudence , unconsciousness may entitle the Criminal Defendant to the Defense of Automatism , an Excusing Condition which allows a defendant to argue that they should not be held Criminally Liable for what would otherwise have been Action s or Omissions which broke the Law . Courts are called upon to consider whether "falling asleep" (especially while Driving or during any other safety-critical activity) can be an acceptable defense because natural sleep rarely overcomes an ordinary person without warning; however incidents related to Epileptic Seizure s, Neurological dysfunctions and Sleepwalking may be considered acceptable excusing conditions because the loss of control may not be foreseeable. For a detailed discussion, see Automatism (case Law) .

On the other hand, someone who is less than fully conscious cannot give Consent to anything. This is relevant in the case of Sexual Behavior (not allowed with such a person), and also in the case of a patient giving Informed Consent with regard to starting or stopping a treatment, and Euthanasia .

In many countries, First-aiders must legally obtain consent from a conscious casualty during an emergency before they can commence CPR or first aid. If consent is denied, the first-aider can legally do nothing. In the situation where the casualty is unconscious, in most cases, the first-aider can legally assume consent.
