Diagnosis and treatment
Generally speaking, we could say personality traits are enduring patterns of interaction with the world and standpoints from which the world is viewed.
Each individual has his/her own personality traits that make him/her unique. When these personality traits are persistent, inflexible, pervasive, they cause distress or functional impairment on different areas (occupational, social…), and have their onset in adolescence or early adulthood, we call it a personality disorder.
Classically they have been distributed into three main groups:
Group A: Paranoid personality disorder, schizoid personality disorder and schizotypal personality disorder. These subjects are usually perceived as eccentric or weird people.
Group B: Borderline personality disorder, histrionic personality disorder, narcissistic personality disorder, and antisocial personality disorder. These individuals can be dramatic, emotional or erratic.
Group C: Dependent personality disorder, obsessive-compulsive personality disorder, and avoidant personality disorder. They tend to be anxious or easily frightened people.
Personality disorders are a wide, complex group, and to deepen into each kind goes beyond the purpose of this webpage. However, they are relatively frequent and they cause distress and problems in society.
