Personality Disorders

Personality disorders are a group of mental health conditions that affect how a person thinks, feels, behaves and relates to others. There are many different types of personality disorders, but they can be broadly classified into three clusters: A, B and C.

Cluster A

Cluster A personality disorders are characterized by odd, eccentric or paranoid thinking or behaviour. They include paranoid personality disorder, schizoid personality disorder and schizotypal personality disorder. People with these disorders may have difficulty trusting others, forming close relationships, expressing emotions or adapting to social situations.

Cluster A personality disorders are a group of mental health conditions that involve odd, eccentric, or distrustful patterns of thinking, feeling, and behaving. They are classified into three types: paranoid personality disorder, schizoid personality disorder, and schizotypal personality disorder. Here is a brief overview of each type:

• paranoid personality disorder: This disorder is characterized by a pervasive and unjustified mistrust of others, often leading to suspicion, doubt, and hostility. People with this disorder may believe that others are lying, cheating, exploiting, or harming them without any evidence. They may also have difficulty trusting or confiding in others, and may perceive innocent remarks or actions as threats or insults. They may also hold grudges and react angrily to perceived slights.
• Schizoid personality disorder: This disorder is characterized by a lack of interest and detachment from social relationships, as well as a restricted range of emotional expression. People with this disorder may prefer to be alone and have little or no desire for intimacy or friendship. They may also have difficulty expressing emotions or reacting appropriately to emotional situations. They may appear cold, aloof, or indifferent to others.
• Schizotypal personality disorder: This disorder is characterized by peculiar beliefs, behaviours, and appearance, as well as social anxiety and paranoia. People with this disorder may have unusual or distorted thoughts or perceptions, such as believing they have special powers or abilities, or hearing voices that are not there. They may also have odd speech patterns, dress in unusual ways, or display strange mannerisms. They may also be suspicious of others and avoid close relationships.

Cluster B

Cluster B personality disorders are characterized by dramatic, emotional or impulsive thinking or behaviour. They include antisocial personality disorder, borderline personality disorder, histrionic personality disorder and narcissistic personality disorder. People with these disorders may have difficulty controlling their impulses, regulating their emotions, respecting boundaries or empathizing with others.

According to the DSM-5, the diagnostic manual for mental disorders, there are four common types of Cluster B personality disorders: antisocial personality disorder, borderline personality disorder, histrionic personality disorder, and narcissistic personality disorder. These disorders are characterized by dramatic, emotional, and erratic behaviour, as well as difficulties in maintaining healthy and stable relationships. People with these disorders may also experience impulsivity, self-destructiveness, distress, and impairments in various aspects of their lives. Each disorder has its own unique symptoms or traits, which can be summarized as follows :

• Antisocial personality disorder: A pattern of disregard for and violation of the rights of others, often involving deceitfulness, manipulation, aggression, rule-breaking, and lack of remorse.
• Borderline personality disorder: A pattern of instability in self-image, mood, and interpersonal relationships, often involving impulsive behaviour, chronic feelings of emptiness or abandonment, intense anger, and suicidal gestures.
• Histrionic personality disorder: A pattern of excessive emotionality and attention-seeking behaviour, often involving provocative interactions, theatrical expressions, and a false sense of intimacy.
• Narcissistic personality disorder: A pattern of grandiosity, need for admiration, and lack of empathy, often involving a sense of superiority, entitlement, exploitation, and negative reactions to criticism.

The causes and risk factors for Cluster B personality disorders are not fully understood, but they may involve genetic, biological, psychological, and environmental factors. Treatment options may vary depending on the specific disorder and the individual’s needs and preferences. They may include psychotherapy, medication, or a combination of both.

Cluster C

Cluster C personality disorders are characterized by anxious, fearful or dependent thinking or behaviour. They include avoidant personality disorder, dependent personality disorder and obsessive-compulsive personality disorder. People with these disorders may have difficulty coping with stress, making decisions, asserting themselves or being independent.

• Avoidant personality disorder (APD) is marked by a pervasive pattern of social inhibition, feelings of inadequacy, and hypersensitivity to negative evaluation. People with APD avoid social situations and interpersonal relationships because they fear being rejected, criticized, or humiliated. They often have low self-esteem, self-doubt, and feelings of inferiority. They may also experience chronic anxiety, depression, and loneliness. The causes of APD are not fully understood, but some factors that may contribute to its development include genetic predisposition, early childhood trauma, parental rejection or criticism, and social isolation. The treatment of APD involves psychotherapy, especially cognitive-behavioural therapy (CBT), which aims to challenge and modify the negative beliefs and assumptions that underlie the avoidant behaviour. Medication may also be prescribed to help reduce anxiety and depression symptoms.
• Dependent personality disorder (DPD) is characterized by a pervasive and excessive need to be taken care of by others. People with DPD have difficulty making decisions, expressing opinions, and initiating activities without the guidance and approval of others. They tend to be submissive, clingy, and fearful of separation or abandonment. They often lack self-confidence, self-reliance, and autonomy. Furthermore, they may also experience chronic anxiety, depression, and resentment. The causes of DPD are not well known, but some factors that may play a role include genetic vulnerability, early childhood experiences of loss or separation, overprotective or authoritarian parenting, and cultural influences. The treatment of DPD involves psychotherapy, especially CBT, which aims to help the person develop a more realistic and positive sense of self-worth, assertiveness skills, and coping strategies for dealing with stress and emotions. Medication may also be used to help alleviate anxiety and depression symptoms.
• Obsessive-compulsive personality disorder (OCPD) is defined by a pervasive pattern of preoccupation with orderliness, perfectionism, and control. People with OCPD are rigid, inflexible, and meticulous in their work and personal life. They have high standards for themselves and others, and often impose strict rules and regulations on themselves and others. They tend to be stubborn, intolerant, and critical of deviations from their expectations. Furthermore, they may also experience chronic stress, frustration, anger, and dissatisfaction. The causes of OCPD are not clear, but some factors that may influence its development include genetic factors, temperament traits, parental modelling or reinforcement of perfectionistic behaviour, and cultural values. The treatment of OCPD involves psychotherapy, especially CBT or schema therapy, which aims to help the person identify and challenge the maladaptive beliefs and schemas that drive their compulsive behaviour. Medication may also be helpful to reduce anxiety or depression symptoms.
