[Psychopathy in children and teenagers: models, theories and the latest research].

Most research about psychopathy have been conducted on adults. It is important to focus on the study of psychopathy in children to better understand the evolution of this disorder. This article focuses on a brief review of the contributions from psychology, where trait callous unemotional is closely related to the presence of antisocial behavior and conduct disorders, therefore, is an important factor in development of psychopathy. Also, we reviewed from the perspective of neuroscience where we found a reduced response of the amygdala in young people with presence of characteristic high scores on callous unemotional and psychopathy. We have also found an abnormal response in the ventromedial prefrontal cortex. It is important to note these results because children with these characteristics are very difficult to socialize.
