People with ADHD and disruptive behavioral disorders share 80% of genetic variants associated with antisocial behavior and aggression. Read More
Compared to typically developing children, those with disruptive behavioral disorders, characterized by antisocial behaviors and aggression, had less gray matter in the amygdala and hippocampus. Read More
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." Read More
People with a life-long history of antisocial behavior had decreased mean surface area of the brain and lower mean cortical thickness than those with no history of antisocial behavior. Much of the cortical thinning was in areas associated with emotional regulation, motivation, and goal-directed behavior. Read More
Children who exhibit less fear and desire for social connection, and who engage less in imitative behaviors, are more likely to develop callous-unemotional traits which may later lead to antisocial behaviors. Read More
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.

Researchers reveal the neurobiology and typical behavior associated with psychopathic personalities. The paper explores the red flags that might mean you are in a relationship with a psychopath. Read More
Researchers report people should look more deeply into the environmental factors and mental health issues surrounding those involved in school shootings, and not simply blame peer rejection. Read More
