Understanding Personality Disorders

Choose a preferred language

Personality is more than being friendly or having a good sense of humor. It’s the way a person thinks about and relates to the world. A personality disorder can make it hard for a person to relate to others in healthy ways. But there is hope. A doctor or mental health professional can help.


What are the symptoms of a personality disorder?

People with personality disorders have a hard time forming normal relationships. They often have trouble with school or work. They may often feel depressed, sad, and alone. There are many types of personality disorders. Each has specific symptoms. But all greatly disrupt the life of the affected person and those around them.


What causes personality disorders?

No one knows what causes these disorders. They are sometimes triggered by childhood abuse or neglect. Research with twins suggests this illness may have hereditary (genetic) links. It's also five times more common among people who have a close relative with the disorder. They also may occur when certain brain chemicals are out of balance. Most likely, both genetics and a person’s environment and experiences play a role.


What can be done?

Certain types of therapy can help treat these disorders. Medicines may help relieve symptoms. Talk therapy and medicines work best when used together. Many people with this disorder don’t realize or admit that they need help. It may take a while before treatment begins to work. But most people who get good treatment live a healthier, happier life.
