(1) The patient suffers from a physical or mental disease, disorder, or defect;
(2) The patient is imminently dangerous to self or others;
(3) The proposed treatment is medically appropriate; and
(4) After considering less intrusive alternatives, treatment is necessary to forestall the danger posed by the patient.
