Personality is a distinct set of traits, behaviors, beliefs, and patterns. People who have a personality disorder have a hard time dealing with other people. Those who have antisocial personality disorder (APD) ignore normal rules of social behavior and are impulsive and reckless. This means they often have aggressive and violent relationships. They show no respect for others and do not feel remorse for their actions. Early signs include lying, stealing, fighting, and missing school. People who have APD are at high risk for substance abuse, especially alcohol. This is true because alcohol and drugs can help relieve the tension, irritability, and boredom they feel. These problems continue into adulthood. Diagnosis is made after the age of 18.

What is going on in the body?

Experts are not sure what is going on in the body that may be related to this condition. Further study is needed.

What are the causes and risks of the condition?

Experts do not know the specific causes of APD. The disorder occurs much more often in people who have a parent with APD. So, experts think that biological and genetic factors play a key role. APD is four times more common in men than in women.

Experts also believe that frequent exposure to criminal behavior and substance abuse contributes to the development of APD. Children raised in a chaotic, neglectful, harsh, and abusive home are also at higher risk.
