Definitions of legal insanity differ from state to state. There are also several standards for measuring insanity. The first is often called the M'Naghten Rule, which comes from an 1843 case where a man (Daniel M'Naghten) was found not guilty of an attempted assassination of the Prime Minister of Britain because he was insane. The public outrage following M'Naghten's acquittal lead to the creation of the M'Naghten Rule. According to the M'Naghten Rule, a defendant could not be held responsible for his actions if, as a result of his mental disease or defect, he did not know that his act would be wrong or did not understand the nature and quality of his actions.
The M'Naghten Rule was used until the 1950's when the Durham test became the new standard (Durham v. United States). In Durham, the court ruled that a person was legally insane if he "would not have committed the criminal act but for the existence of a mental disease or defect."
By the 1970's, most courts had adopted the MPC (Modern Penal Code) standard, which was a compromise between M'Naghten and Durham. Today, most states have adopted their own standards based on the MPC.

Insanity is not a medical or psychological term. It is an outdated and stigmatizing term to describe mental health issues. Mental health conditions are complex and can vary greatly, so it's important to seek professional help and avoid using outdated or stigmatizing language.
