The term psychopath is used in psychology to describe individuals who have an unusual personality or are sociopaths.
It refers to those who are extremely self-centered, egocentric, emotionally manipulative and possess a sense of entitlement, the Diagnostic and Statistical Manual of Mental Disorders says.
“People with psychopathic traits often have an aggressive and vindictive personality that often causes them to act aggressively, even to the point of violence,” Dr. Jennifer Belsky, who is based at Harvard Medical School and a clinical psychologist, said.
In some cases, people who have these personality traits can display violence, she said. “
We need to understand how these traits manifest, and what triggers them and what the triggers might be,” she added.
In some cases, people who have these personality traits can display violence, she said.
Some people are prone to being angry and possess an aggressive streak, which could lead to aggression.
Others are able to manipulate others, but do not possess psychopathic tendencies.
“When we get into the behavior of people who are psychopaths, we find out that the psychopaths are not really in control of their behavior,” Dr Belski said.
Dr. Belska said that psychopaths often engage in behaviors such as: lying, cheating, stealing, lying to protect themselves and others, stealing from others, lying in public and stealing from people they care about.
In a recent study published in the journal Personality and Individual Differences, Dr. Andrew A. Seidel, of New York University and Harvard Medical Schools, and his colleagues examined personality traits, including those linked to psychopathic personality, in more than 3,000 people who were tested for psychopathic disorder in the United States between 2000 and 2010.
Among those, a large majority (68 percent) reported having a psychopathic trait, while just over 10 percent reported a non-psychopathic trait.
The findings revealed that psychopathic behavior in some people can be triggered by their own behavior and the behavior they have experienced.
People with psychopaths who have been victims of violence were more likely to display antisocial personality disorder than those who did not, Dr Seidel said.
The authors said the results suggest that psychopathics may exhibit a range of negative behaviors.
Dr Bilsky said the study also found that those with psychopathological traits are more likely than others to be victims of domestic violence.
She said some of the findings were particularly striking because many psychopaths have an unhealthy relationship with their spouses, and that may be related to their aggressive behavior.
“They may have a lot of anxiety about the safety of their children, or a lot anxiety about their relationships with their spouse,” Dr Seiden said.
For example, the authors found that people with psychopathial traits who had been physically abused or stalked were more than three times as likely to be victimized as people who had not been abused or victimized.
In the current study, Dr Balsky and her colleagues looked at the differences between the psychopathic-and non-pathological-types in personality traits.
They looked at five personality traits: neuroticism, agreeableness, openness to experience, neuroticism with an antisocial attitude, openness with an aggressive personality, and neuroticism without an antisociety.
These were the five traits that were most strongly associated with psychopathology, they found.
The researchers then compared the personality traits in a large sample of people with and without psychopathic symptoms.
The results showed that psychopathological-type people were more narcissistic, antisocial, and violent than non-phenomenally psychopathic people.
“Our findings show that the degree to which people who suffer from psychopathy express psychopathic characteristics may be linked to their risk for perpetrating antisocial behavior,” they wrote.
Dr Seidels team said the findings should help researchers better understand the dynamics of psychopathic behaviors.
“In our view, this research raises the possibility that there may be a common underlying genetic mechanism that mediates some aspects of psychopathology and may be at least partly responsible for the variation in psychopathic phenotype,” they said.
A similar study published earlier this year found that patients with borderline personality disorder have more psychopathic and antisocial traits than those without the disorder.
Dr Paul Kostyuk, a psychiatrist at the University of Southern California who was not involved in the study, said that it was important to study psychopaths because their behavior could have important consequences for patients.
“There is a risk that the risk for future aggression could increase with the presence of psychopaths,” he said.
While this study does not prove that people who fall into the psychopath spectrum have psychopathic features, Dr Kostyanko said the finding may help psychiatrists to better understand how people with these disorders manifest their behaviors.
He said there were other research studies that suggested that individuals who were antisocial in childhood had been diagnosed with antisocial behaviors in adulthood, although this was not clear.
“So this study is really helping us to understand this disorder,” Dr K
