Justipedia explains Irresistible Impulse Test
In order for a defendant to pass the irresistible impulse test, it must be proven that a mental illness existed and also that this mental illness prevented the person from being able to act in accordance with the law. If both of these conditions are met, then a defendant may be able to successfully plead not guilty by reason of insanity.
Certain mental illnesses, such as schizophrenia or Alzheimer's disease, can legitimately cause a person to lose control of their actions.
