People with personality disorders usually have a hard time getting along with others and dealing with everyday problems in the ways that are expected by a cultural group. They commonly believe that their way of thinking and behaving is completely normal. However, they tend to have a view of the world that is quite different than others. As a result, they may find it difficult to participate in social, educational, and family activities. They also place blame on others for their challenges. These behaviors and attitudes often cause problems and limitations in relationships, social encounters, and work or school settings. They may also make people with personality disorders feel isolated, which can contribute to depression and anxiety.
The cause of personality disorders isn’t known. However, it is believed that they may be triggered by genetic and environmental influences, most prominently childhood trauma.
Personality disorders tend to emerge in the teenage years or early adulthood. The symptoms vary depending on the specific type of personality disorder. Treatment typically includes talk therapy and medication.
