What is a personality disorder?
If you have a personality disorder, you’re likely to differ from an average person in terms of the way you think, feel or relate to other people.
Â
Personality disorders typically emerge in adolescence and then continue into adulthood.
Â
There are different types of personality disorders which come alongside different sets of symptoms. The different types of personality disorder are grouped into three clusters: A, B and C.
The different clusters of personality disorders
Cluster A personality disorders
- Difficulty relating to others – often a lack of wish to form relationships
- Odd and eccentric behaviours
The types of personality disorder that fall under cluster A are paranoid, schizoid and schizotypal.
Cluster B personality disorders
- Difficulty relating to others but often there is a wish to form close relationships
- Dramatic, emotional and unpredictable behaviours
The types of personality disorder that fall under cluster B are borderline, antisocial, histrionic and narcissistic.
Cluster C personality disorders
- Difficulty relating to others, often there is a wish to form close relationships
- Anxious and fearful thinking and behaviour
The types of personality disorder that fall under cluster C are avoidant, dependent and obsessive-compulsive (the latter being a different diagnosis to obsessive-compulsive disorder).

Treatment for personality disorders
Therapy is the main form of treatment for personality disorders. Dialectical behaviour therapy (DBT) and mentalisation-based treatment (MBT) have been shown to be effective for the treatment of borderline personality disorder (BPD). Schema therapy (ST) and cognitive analytic therapy (CAT) have a wider applicability and can be effective approaches for the treatment of a range of different types of personality disorder.
