What is Personality Disorders?


Personality disorders are a group of mental disorders characterized by maladaptive patterns of behavior, thoughts and functioning. A person with a personality disorder has difficulty perceiving and relating to situations and people, which can affect interpersonal relationships, social activities, work and school.


Types  of Personality disorder

Personality disorders are grouped into three broad clusters, A, B, and C, according to the DSM-5.

Cluster A personality disorders:

  • Paranoid personality disorder– a person may appear suspicious and distrustful. 
  • Schizoid personality disorder–  a person may appear aloof, detached, and cold, a “loner.” They may shy away from close social contact with others. 
  • Schizotypal personality disorder– are also detached from social relationships, and they may have cognitive and perceptual distortions, poor social skills, and delusional thoughts.

Cluster B personality disorders:

  • Antisocial personality– a person may appear to enjoy bullying or intimidating people. They may appear deceitful and manipulative.
  • Borderline personality – the person essentially lacks a sense of self and, as a result, experiences feelings of emptiness and fears of abandonment. Self-harm and emotionally instability may occur.
  • Histrionic personality – a person craves for attention and have a fear of being ignored.  They want to be at the center of everybody’s attention. 
  • Narcissistic personality– a person may have inflated sense of one’s own importance, a craving for admiration and a lack of regard for others’ feelings. 

Cluster C personality disorders:

  • Avoidant personality–  a person believe that they are unappealing, or inferior, and constantly fear being embarrassed, criticized, or rejected.
  • Dependent personality– a person may lack self-confidence, overly-dependent on others and has a deep fear of separation.  They tend to be nonassertive, and submissive.
  • Obsessive-compulsive personality– excessive concern with perfectionism and work at the expense of close personal relationships. The individual feels an overwhelming need to be in control.
