insanity

A legal rather than a medical term, implying a disorder of the mind of such degree as to interfere with a person's ability to be legally responsible for his or her actions. The term is little used in medicine but might equate to PSYCHOSIS. A defence of insanity, in law, is governed by the McNaughten Rules. These state, in part, ‘The jurors ought to be told in all cases that every man is presumed to be sane and to possess a sufficient degree of reason to be responsible for his crimes, until the contrary be proved to their satisfaction: and that to establish a defence on the grounds of insanity, it must be clearly proved that, at the time of the committing of the act, the party accused was labouring under such a defect of reason, from disease of the mind, as not to know the nature and quality of the act he was doing or, if he did know it, that he did not know he was doing what was wrong.’
