A person with a personality disorder thinks, feels, behaves or relates to others very differently from the average person. There are several different types of personality disorder.
Symptoms vary depending on the type of personality disorder.
A person with borderline personality disorder (one of the most common types) tends to have disturbed ways of thinking, impulsive behaviour and problems controlling their emotions. They may have intense but unstable relationships and worry about people abandoning them.
A person with antisocial personality disorder will typically get easily frustrated and have difficulty controlling their anger. They may blame other people for problems in their life, and be aggressive and violent, upsetting others with their behaviour.
Someone with a personality disorder may also have other mental health problems, such as depression and substance abuse.
