Personality disorders

What are personality disorders?

Personality disorders are names given to explain and categorise patterns of thought, behaviours and feelings. Personality disorders usually cause a great deal of distress to the individual and others around them because they affect a person's ability to function normally.

Personality disorders are chronic, which means they usually start in childhood and continue throughout a person's life. These problems affect many aspects of the person's life including work, play and relationships with themselves and others. However, this does not mean every part of their life is bad, or unhappy, just that their thoughts, feelings and behaviours may influence the way they think, feel and experience things.

What are the different types of personality disorders, and how are they classified?

There are 10 personality disorders that are divided into three clusters. Cluster A is signified by odd or eccentric behaviour and includes paranoid, schizoid, and schizotypal personality disorders. Cluster B is determined by dramatic, emotional or erratic behaviour and involves antisocial, borderline, histrionic, and narcissistic personality disorders. Cluster C is classified as anxious or fearful behaviours and includes avoidant, dependent and obsessive-compulsive personality disorders.
