Dependent personality disorder is characterized by dependent and submissive behavior. The person often defers the majority or all decision-making to someone else. People with this type of personality disorder are not aware that their thoughts and behaviors are inappropriate.
It is not clear what causes personality disorders, but it is likely a combination of genetic factors and a person's environment.
A personality disorder is most likely a combination of chemical or electrical imbalances in the brain and a reaction to traumatic personal experiences.
