Personality Disorders - Causes
What causes personality disorders?
It is not clear what causes personality disorders. It seems that a mix of factors can mean some people develop personality disorders later in life. These can include biological factors (when it is passed on through your genes) and the environment around you when you were growing up.
Many people diagnosed with personality disorders have experience of trauma. These can include difficulties growing up, including childhood neglect or physical, emotional or sexual abuse. When you are growing up, you learn to cope with emotional changes and make relationships with other people. Children who are abused or neglected often do not learn these things, so they may find it more difficult to manage how they feel when they are adults.
This does not mean that all people who experience trauma will develop personality disorders, but they may be more likely to.
