Personality Disorders

Personality disorders are mental health conditions characterized by inflexible patterns of behavior, thinking, and perception. These patterns typically emerge in adolescence or early adulthood and persist over time.

Maladaptive personality patterns can disrupt personal, social, and occupational functioning. However, individuals with personality disorders may not fully recognize how their thoughts and behaviors affect their relationships and interactions with others.

Personality disorders are categorized into three main groups, or “clusters.” It’s possible for an individual to meet criteria for more than one type of personality disorder.

Cluster A Personality Disorders

Cluster A personality disorders are characterized by odd or eccentric behaviors and thought patterns.

Cluster A includes three specific personality disorders:

1. Paranoid Personality Disorder: People with paranoid personality disorder have a pervasive distrust and suspicion of others, believing that others are trying to harm, deceive, or exploit them. They are often hypervigilant, have difficulty trusting others, and may interpret innocent actions as malevolent.
2. Schizoid Personality Disorder: Individuals with schizoid personality disorder tend to be emotionally detached and have little interest in forming close relationships. They often prefer solitary activities and may have limited emotional expression.
3. Schizotypal Personality Disorder: People with schizotypal personality disorder display eccentric behaviors, beliefs, and thought patterns. They may have unusual beliefs or magical thinking, experience social anxiety, and have difficulty forming and maintaining close relationships.

Cluster B Personality Disorders

Cluster B personality disorders are characterized by significant emotional reactivity and difficulty regulating emotions, leading to impulsive and often maladaptive behaviors. Individuals with Cluster B disorders may struggle with interpersonal relationships and experience difficulties in maintaining boundaries. Cluster B includes four specific personality disorders:

1. Borderline Personality Disorder: Individuals with borderline personality disorder, or BPD, often struggle with intense emotions, unstable self-image, and turbulent interpersonal relationships. They may engage in impulsive behaviors, such as self-harm or substance abuse, and experience chronic feelings of emptiness and fear of abandonment.
2. Histrionic Personality Disorder: Individuals with histrionic personality disorder seek attention and validation from others and may exhibit overly dramatic or attention-seeking behavior. They have a strong need for approval and may use their physical appearance or emotions to gain attention.
3. Narcissistic Personality Disorder: Individuals with narcissistic personality disorder may demonstrate an inflated sense of self-importance and a deep need for admiration. They may lack empathy for others and have an excessive preoccupation with their own achievements and fantasies of success.
4. Antisocial Personality Disorder: People with antisocial personality disorder often demonstrate a disregard for the rights and feelings of others. They may engage in deceitful, manipulative, and exploitative behaviors without remorse. Impulsivity, aggression, and a history of legal problems are common.

Cluster C Personality Disorders: Cluster C personality disorders are characterized by chronic and pervasive feelings of anxiety and fear, which often lead to avoidance and reliance on others for support and decision-making. Individuals with these disorders may have difficulty asserting themselves, setting boundaries, and engaging in social situations due to their heightened sensitivity to criticism and rejection.

Cluster C includes three specific personality disorders:

1. Avoidant Personality Disorder: Individuals with avoidant personality disorder have a deep-seated fear of rejection, criticism, and disapproval, which leads them to avoid social situations and interpersonal relationships. They often have feelings of inadequacy and low self-esteem.
2. Dependent Personality Disorder: People with dependent personality disorder have an excessive need to be taken care of by others. They fear being alone and struggle to make decisions without the reassurance and approval of others. They may become submissive and cling to relationships, even if they are unhealthy.
3. Obsessive-Compulsive Personality Disorder: Individuals with obsessive-compulsive personality disorder are preoccupied with rules, order, and perfectionism. They have an intense need for control and struggle with flexibility and openness to new ideas. This is different from Obsessive-Compulsive Disorder (OCD), which is an anxiety disorder, but shares some similarities in terms of obsessive thinking and compulsive behaviors.
