[Acting out as criminal impulse. History, Definitions, Forensic aspects].

The present article aims to conduct a comprehensive review of the existing scientific literature on this human behavioral modality, impulsive and transient, which escapes the conscious control of the subject, from a psychopathological and forensic approach. To achieve this, historical points about the different nuances of the topic will be made, supplying a panoramic and critical overview of it. It can be said that these are implicit memories about past traumatic situations that, because of a present reenactment of the unpleasant event through a dissociative mechanism, generate in the individual an impulsive aggressive reaction, over which the person has no control or awareness.
