Not all psychopaths are violent. Study reveals why some are ‘successful’ instead

While psychopathy is generally associated with antisocial behaviors, many with the personality trait develop successful careers. A new study supports a novel model of psychopathy which runs contradictory to existing models of the disorder, focusing on the strengths associated with psychopathy, rather than just the deficits. Researchers found higher initial psychopathy was associated with a steeper increase of general inhibitory control and the inhibition of aggression over time. The effect was magnified among those who were "successful."

Abnormal expression of genes in psychopathy

Psychopathy is associated with altered expression of genes and immune responses related to molecular pathways. In neurons, the up-regulation of PRL10P9 and ZNF132 and down-regulation of CDG5 and OPRD1 were linked to psychopathic behaviors. The genetic expression explained up to 92% of the variance of psychopathic symptoms. Researchers speculated these genes may be relevant to the lack of empathy and emotional callousness associated with psychopathy, as previous studies have linked a number of these genes to ASD and problematic social behaviors.
