title: Stimuli triggering violence in psychoses.
abstract: Various behavioral and neurophysiological models are suggested to objectify and quantify the defense of insanity and to assess dangerousness in someone who is being considered for release from custody. Two cases are presented that show a pattern of specific relationships between traumatic experiences in youth and a later trigger stimulus that releases homicidal action. Until a refined classification system and neurophysiological understanding of sudden aggression can be achieved, forensic psychiatrists should be aware of the psychotic trigger reaction within a clinical psychiatric model.
