Symptoms of antisocial personality disorder, which is most common in men, include frequent lying and deception to exploit others, sense of superiority, disregard for ethics, recurrent encounters with the law and a tendency to be in dysfunctional relationships, explains Mayo Clinic. Lack of empathy and risk-taking behaviors are other signs.
A person with antisocial personality disorder may exhibit irresponsible behavior at work, or he may neglect or abuse children, according to Mayo Clinic. He may appear incapable of learning from past negative consequences or of feeling remorse after causing harm to others. Another common trait in people with antisocial personality disorder is an ability to manipulate others, either for personal gain or amusement, through the use of wit or charm.
People diagnosed with antisocial personality disorder are often referred to as sociopaths or psychopaths among laypersons, although neither sociopathy nor psychopathy are recognized diagnoses within the mental health community, notes Psych Central. This disorder is diagnosed 70 percent more frequently in men than in women. The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders specifies that only individuals aged 18 years or older can be diagnosed with antisocial personality disorder. However, early warning signs, such as cruelty to animals and bullying others, may be seen in children, notes Mayo Clinic.
