Despite these limitations, data suggest that exposure to early relational trauma can play a relevant role in the onset of violent offending behaviour, and this can be related to an early age of exposure to abuse and neglect and the subsequent development of psychopathic traits.
Childhood trauma affects vulnerability to different forms of psychopathology and traits associated with it. Parental behaviors such as rejection, abuse, neglect or over protection show some relationship with the development of detrimental psychopathic traits.
A common question is: “What causes psychopathy?” As is true for other developmental disorders, there is no single cause of psychopathy. Research indicates that psychopathy results from a complex combination of genetic and environmental (non-genetic) factors.
Whereas results from several studies have indicated that total psychopathy scores are unrelated to PTSD symptoms (Sellbom, 2015; Willemsen et al., 2012), other studies report a positive relationship between PTSD symptoms and overall psychopathy scores (e.g., Blonigen et al., 2012; Sharf et al., 2014; Tatar et al., 2012 ...
Children that show a lack of empathy, lack of guilt and have shallow emotions, defined as callous-unemotional traits, are at increased risk of developing psychopathy in adulthood.
Although sociopathy and psychopathy cannot be diagnosed until someone is 18, one of the hallmarks of both conditions is that they usually begin in childhood or early adolescence. Usually, the symptoms appear before the age of 15, and sometimes they are present early in childhood.
Although both biological and environmental factors play a role in the development of psychopathy and sociopathy, it is generally agreed that psychopathy is chiefly a genetic or inherited condition, notably related to the underdevelopment of parts of the brain responsible for emotional regulation and impulse control.
The study showed that psychopaths have reduced connections between the ventromedial prefrontal cortex (vmPFC), the part of the brain responsible for sentiments such as empathy and guilt, and the amygdala, which mediates fear and anxiety.
What causes sociopathy? Experts believe environmental factors like childhood trauma, abuse, neglect, or impoverishment are major influences in sociopathy: Instead of being born with these traits, people learn sociopathic behaviors to cope with unstable or chaotic living environments.
Psychopaths do not lack empathy, rather they can switch it on at will, according to new research. Placed in a brain scanner, psychopathic criminals watched videos of one person hurting another and were asked to empathise with the individual in pain.
Conclusions. Findings of this study suggest that an early exposure to relational trauma in childhood can play a relevant role in the development of more severe psychopathic traits.
However, there was no association between having a biological criminal mother and psychopathic personality traits for adoptees. Psychopathic personality traits are transmitted from father-to-offspring due to genetic reasons.
Childhood abuse and neglect have been associated with the subsequent development of diverse forms of psychopathology, including both internalizing and externalizing symptoms.
Causes. Early exposure to a dysfunctional environment is likely a factor in the development of psychopathic traits. Children who have been physically abused, neglected, and separated from their parents are more likely to develop psychopathy. Poor bonding with a parent is also thought to be a factor.
Factor analyses of the Psychopathic Personality Inventory (PPI)typically yield two factors: Fearless Dominance (FD) and Self-Centered Impulsivity (SCI).
The current belief is that psychopathy generally comes from genetic factors, such as parts of the brain not developing fully, while sociopathy results from an interruption in personality development by abuse or trauma in childhood.

“Using MRI scans we found that psychopaths had structural brain abnormalities in key areas of their 'social brains' compared to those who just had ASPD,” he said. He noted there is a clear difference between those with ASPD and those with ASPD+P.
lack of empathy, guilt, conscience, or remorse. shallow experiences of feelings or emotions. impulsivity, and a weak ability to defer gratification and control behavior.
Thanks to Hollywood, we tend to think of psychopaths as knife-wielding criminals, but science shows some high-functioning psychopaths can actually be hard to spot. So hard, in fact, that some psychopaths don't know they meet the definition for the condition.
Although severe psychopathy affects just about 1% of people, some research suggests that close to 30% of us have some level of psychopathic traits.
Psychopathy is an extreme form of antisocial behavior, with about 1% prevalence in the general population, and 10–30% among incarcerated criminal offenders. Although the heritability of severe antisocial behavior is up to 50%, the genetic background is unclear.
Psychopathy is a mental disorder according to both the Wakefield definition cited in this study and American Psychiatric Association criteria (American Psychiatric Association, 2000). More studies of the harm done to family members by psychopathic individuals are needed.
