Psychosis can be graded into six levels, with level 0 being the absence of any of the behaviors on levels 1-5. level 1 is a patient who talks nonsense, threatens others, or yells, but only verbally, not behaviorally. level 2 is a patient who vandalizes property, but only in the home, and can stop when persuaded. level 3 is a patient who vandalizes property in the home and in public, and cannot be persuaded to stop. Level 4 is when the patient continues to hurt people or destroy things at home or in public and cannot be persuaded to stop. Level 5 is when the patient is armed with knives, firearms, or other controlled dangerous weapons, commits violent acts against people, or commits arson or explosions. In the case of Level 3 or higher psychosis, the patient should be reported to the public security authorities for better management.
