Personality Disorders According to the DSM-5

In this post, I’ll say a few words about personality disorders according to the DSM-5. The DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, 5th edition) is a widely used classification system for mental disorders (though not the only one). 

Personality disorders are a group of persistent, inflexible patterns of behavior, thinking, and feeling that conflict with cultural norms and negatively impact an individual’s functioning. The DSM-5 divides personality disorders into three categories—A, B, and C.

Cluster A (bizarre/eccentric personality disorders)

• Paranoid personality disorder—characterized by distrust of others, suspicion, and the belief that others intend to harm or deceive them, even when there is no evidence to support this.
• Schizotypal personality disorder—characterized by eccentric behavior, bizarre beliefs, difficulties in forming relationships with others, and frequent shy or withdrawn behavior.
• Schizoid personality disorder—characterized by emotional detachment, a lack of interest in relationships with others, a tendency toward withdrawal, and a limited ability to express emotions.

Cluster B (Dramatic/Unstable Personality Disorders)

• Histrionic personality disorder—characterized by excessive emotionality, dramatization, a need to be the center of attention, and shallow and volatile emotions.
• Antisocial personality disorder—characterized by a failure to adhere to social norms, disregard for the rights of others, manipulation, deceit, and a lack of guilt.
• Borderline personality disorder (emotionally unstable) — characterized by emotional instability, impulsivity, difficulty maintaining stable relationships, and an intense fear of abandonment.
• Narcissistic personality disorder—characterized by an inflated sense of self-worth, a desire for admiration, a lack of empathy, and difficulty maintaining deep relationships with others.

Cluster C (Anxious/Avoidant Personality Disorders)

• Avoidant Personality Disorder—characterized by excessive sensitivity to criticism, feelings of inferiority, and avoidance of social situations out of fear of rejection or misunderstanding.
• Dependent personality disorder—characterized by an excessive sense of helplessness, a need for care and support from others, difficulty making decisions, and a fear of independence.
• Obsessive-compulsive (anankastic) personality disorder—characterized by excessive perfectionism, attention to detail, persistence, and difficulty delegating tasks to others.

The prevalence of these personality disorders may vary depending on the population, and some of them may co-occur in the same individual.

Diagnosing and treating personality disorders can be difficult, but there are effective treatment methods, such as psychotherapy, cognitive-behavioral therapy (CBT), and dialectical behavior therapy (DBT). Supporting people with personality disorders and raising awareness about this topic helps break down stigmas and foster healthier social relationships.
