Types Of Personality Disorders

Personality disorders are divided into three clusters in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), which is a widely used classification system for mental health conditions:

Cluster A - Odd or Eccentric Disorders:

• Paranoid Personality Disorder: Characterized by distrust and suspicion of others, often interpreting benign actions as malevolent.

• Schizoid Personality Disorder: Involves a lack of interest in social relationships, a preference for solitary activities, and emotional detachment.

• Schizotypal Personality Disorder: Features peculiar behaviours, odd beliefs, and unusual perceptions, along with social and interpersonal difficulties.

Cluster B - Dramatic, Emotional, or Erratic Disorders:

• Antisocial Personality Disorder: Marked by a disregard for the rights of others, impulsive behaviours, and a lack of empathy or remorse for harmful actions.

• Borderline Personality Disorder: Characterized by unstable relationships, self-image, and mood, as well as impulsive and self-destructive behaviours.

• Histrionic Personality Disorder: Involves attention-seeking, dramatic, and overly emotional behaviours to gain approval or admiration.

• Narcissistic Personality Disorder: Features a grandiose sense of self-importance, a need for excessive admiration, and a lack of empathy for others.

​

Cluster C - Anxious or Fearful Disorders:

• Avoidant Personality Disorder: Involves social inhibition, feelings of inadequacy, and a fear of rejection or criticism.

• Dependent Personality Disorder: Characterized by an excessive need to be taken care of, submissive behaviours, and difficulty making decisions independently.

• Obsessive-Compulsive Personality Disorder: Different from obsessive-compulsive disorder (OCD), this disorder is marked by preoccupation with order, control, and perfectionism, often at the expense of flexibility and efficiency.

​

Note: while personality disorders are distinct conditions, they can sometimes co-occur with other mental health issues, complicating diagnosis and treatment.

Causes Of Personality Disorders

Personality disorders develop due to a complex interplay of various factors, including genetic, environmental, and social elements. Understanding the precise causes of personality disorders isn’t straightforward, but there are several contributing factors:

​​

• Genetics and Biology: There's evidence that genetic factors play a role in the development of personality disorders. Certain traits and predispositions may be inherited, increasing the likelihood of developing a personality disorder. Differences in brain structure and function have also been observed in individuals with certain personality disorders, suggesting a biological basis.

• Environmental Factors: Childhood experiences and environmental factors can significantly impact the development of personality disorders. Adverse or traumatic experiences, such as abuse, neglect, unstable family environments, or early loss, can contribute to the development of certain personality disorders.

• Social and Cultural Influences: Cultural and social factors also shape the development of personality traits and behaviours. Social expectations, family dynamics, and societal norms can influence how individuals develop and express their personalities.

• Early Developmental Factors: Early life experiences, especially during crucial developmental stages, can have a lasting impact on personality. Attachment patterns, parenting styles, and the quality of relationships during childhood can influence the development of personality traits and coping mechanisms.

• Temperament and Personality Traits: Certain personality traits and temperamental predispositions may contribute to the risk of developing a personality disorder. For instance, a high sensitivity to stress or a tendency toward impulsivity might play a role.

Note: personality disorders don’t have a singular cause; rather, they often result from a combination of these factors. Moreover, not everyone exposed to these risk factors will develop a personality disorder. Factors like resilience, protective environments, and coping strategies can mitigate the impact of risk factors and reduce the likelihood of developing a personality disorder.

Treatment

Psychotherapy:

• Dialectical Behavior Therapy (DBT): Especially effective for borderline personality disorder, DBT focuses on managing emotions, improving relationships, and developing coping skills.

• Cognitive-Behavioural Therapy (CBT): Helps individuals identify and change negative thought patterns and behaviours.

• Schema-Focused Therapy: A long-term therapy focusing on identifying and changing maladaptive patterns in thinking and behaviour.

• Transference-Focused Psychotherapy (TFP): Primarily used for treating borderline and other personality disorders, focusing on exploring and understanding problematic relationship patterns.

• Mentalization-Based Therapy (MBT): Focuses on improving an individual's ability to understand their thoughts and feelings, as well as those of others, particularly in social interactions.

​

Medication:

• While medication is not a primary treatment for personality disorders, it may be prescribed to manage specific symptoms or co-occurring conditions such as depression, anxiety, or mood instability. For example, antidepressants or mood stabilizers might be used to address symptoms associated with certain personality disorders.

​

Hospitalization or Intensive Programs:

• In severe cases or during crises, hospitalization or participation in intensive outpatient programs may be necessary for safety and stabilization.

​

Supportive Services:

• Case Management and Supportive Housing: Help with practical needs, such as securing housing or employment, to support an individual's stability.

• Support Groups: Participation in support groups specific to the individual's personality disorder can provide a sense of community and understanding.

Family or Group Therapy:

• Involving family members or group therapy can aid in improving relationships and understanding the impact of the disorder on both the individual and their loved ones.

​

Self-Management Strategies:

• Learning stress reduction techniques, emotion regulation, and interpersonal skills can be vital for managing symptoms and improving overall functioning.

​

Note: treatment plans for personality disorders are highly individualized and may involve a combination of approaches. The goal of treatment is not to eliminate the personality traits but to help individuals manage symptoms, improve functioning, and enhance their quality of life. Therapeutic relationships and consistent, ongoing support are crucial for individuals with personality disorders. Early intervention and a commitment to long-term treatment can significantly improve outcomes and help individuals develop more effective coping strategies and healthier relationships.
