Historical views and treatment

Madness, the non-legal word for insanity, has been recognized throughout history in every known society. Some traditional cultures have turned to witch doctors or shamans to apply magic, herbal mixtures, or folk medicine to rid deranged persons of evil spirits or bizarre behavior, for example. Archaeologists have unearthed skulls (at least 7000 years old) that have small, round holes bored in them using flint tools. It has been conjectured that the subjects may have been thought to have been possessed by spirits which the holes would allow to escape. More recent research on the historical practice of

for the purposes of an insanity defense. The second question is whether the mental illness interfered with the defendant's ability to distinguish right from wrong. That is, did the defendant know that the alleged behavior was against the law at the time the offense was committed. Additionally, some jurisdictions add the question of whether or not the defendant was in control of their behavior at the time of the offense. For example, if the defendant was compelled by some aspect of their mental illness to commit the illegal act, the defendant could be evaluated as not in control of their behavior at the time of the offense. The forensic mental health specialists submit their evaluations to the court. Since the question of sanity or insanity is a legal question and not a medical one, the judge and or jury will make the final decision regarding the defendant's status regarding an insanity defense. In most jurisdictions within the United States, if the insanity plea is accepted, the defendant is committed to a

Feigning

Feigned insanity is the simulation of mental illness in order to deceive. Amongst other purposes, insanity is feigned in order to avoid or lessen the consequences of a confrontation or conviction for an alleged crime. A number of treatises on medical jurisprudence were written during the nineteenth century, the most famous of which was
Isaac Ray Isaac Ray (January 16, 1807 – March 31, 1881) was an American psychiatrist, one of the founders of the discipline of forensic psychiatry. In 1838, he published ''A Treatise on the Medical Jurisprudence of Insanity'' (Boston), which served as an ...
in 1838 (fifth edition 1871); others include Ryan (1832), Taylor (1845), Wharton and Stille (1855), Ordronaux (1869), Meymott (1882). The typical techniques as outlined in these works are the background for Dr. Neil S. Kaye's widely recognized guidelines that indicate an attempt to feign insanity. One famous example of someone feigning insanity is

Insult

In modern times, labeling someone as insane often carries little or no medical meaning and is rather used as an insult or as a reaction to behavior perceived to be outside the bounds of accepted norms. For instance, the definition of insanity is sometimes colloquially purported to be "doing the same thing over and over again and expecting a different result." However, this does not match the legal definition of insanity.
