PERSONALITY DISORDERS: UPDATES AND CHALLENGES

Abstract

Personality disorders are enduring and inflexible patterns of thinking, feeling and behaving that deviate significantly from cultural expectations and cause distress or functional impairment.  They manifest in adolescence or early adulthood and persist throughout life, affecting various aspects of the individual's life, including relationships, work and mental health.  The complexity of these disorders lies in their pervasive nature, influencing the way the person perceives themselves, others and the world. The DSM-5 (Diagnostic and Statistical Manual of Mental Disorders) categorizes personality disorders into ten distinct types, grouped into three clusters (groups) based on shared characteristics:Cluster A (Eccentric Disorders): This cluster includes Schizoid Personality Disorder, characterized by social detachment and restricted emotional expression; Schizotypal Personality Disorder, marked by discomfort in interpersonal relationships, cognitive or perceptual distortions and eccentric behaviour; and Paranoid Personality Disorder, defined by generalized distrust and suspicion of the motivations of others. Cluster B (Dramatic, Emotional or Erratic Disorders):  This group encompasses Antisocial Personality Disorder, characterized by disregard for the rights of others and lack of remorse; Borderline Personality Disorder, marked by instability in interpersonal relationships, self-image and affect, as well as impulsivity; Histrionic Personality Disorder, which is manifested by excessive need for attention and exaggerated emotionality; and Narcissistic Personality Disorder, characterized by grandiosity, need for admiration and lack of empathy. Cluster C (Anxious or Fearful Disorders):  This cluster includes Avoidant Personality Disorder, defined by social inhibition, feelings of inadequacy and hypersensitivity to negative evaluation; Dependent Personality Disorder, marked by an excessive need to be cared for and fear of separation; and Obsessive-Compulsive Personality Disorder, characterized by an excessive preoccupation with order, perfection and control. It is important to note that the diagnosis of a personality disorder requires a thorough assessment by a mental health professional, taking into account the individual's history, symptoms and impact on their life.  Treatment can involve psychotherapy, such as cognitive-behavioral therapy (CBT) and dialectical behavior therapy (DBT), which have been shown to be effective in helping individuals manage their symptoms and improve their quality of life.  Pharmacotherapy can be used as an adjunctive treatment in some cases, to control symptoms such as anxiety and depression.  Early understanding and treatment are crucial to minimizing suffering and promoting the well-being of those affected by these disorders.
