Types of Personality Disorders Symptoms and Treatment

Types of Personality Disorders - Symptoms and Treatment

Approximately 9% of adults in the United States and 6% of the global population are affected by various types of personality disorders, according to the National Institute of Mental Health (NIMH).

Many personality disorder types usually begin during late adolescence or early adulthood and can cause distress and functional difficulties.

Without proper treatment, some types of personality disorders may persist for a long time.

What is a Personality Disorder?

A personality disorder is an enduring mental health condition that often involves rigid, unhealthy thinking, functioning, and behavioral patterns.

For some people, personality disorders can significantly impact various aspects of life, causing disruptions in work, relationships, and social functioning.

These types of disorders often shape an individual’s personality, self-identity, and interactions with others.

Many times they result in distorted perceptions, abnormal behaviors, and mental or emotional distress.

Personality disorders differ from other conditions like mood disorders such as depression.

A personality disorder affects how an individual perceives or relates to other people, whereas a mood disorder has an impact on a person’s individual emotional state that may cause extreme sadness or happiness.

In general, personality disorders include distorted thinking, as well as difficulties with emotional responses, impulse control, and interpersonal relationships.

Personality Disorder Types and Clusters

The Diagnostic and Statistical Manual of Mental Disorders (DSM-5) categorizes 10 types of personality disorders into 3 clusters:

  1. Cluster A Personality Disorders (odd/eccentric)
  2. Cluster B Personality Disorders (dramatic/emotional/impulsive)
  3. Cluster C Personality Disorders (anxious/fearful)

Identifying a proper diagnosis within each cluster will help determine appropriate treatment options.

  • Extreme perfectionism
  • Distress when unable to meet self-imposed standards

Personality Disorder Treatment

Personality Disorder Treatment

Personality disorder treatment can pose challenges because individuals often do not recognize his or her problematic behavior, so they may be less likely to seek help.

However, when an individual does seek help, there are various forms of therapy that can be beneficial.

Treatment will depend on various factors such as the type of personality disorder, severity, and the prevalence of co-occurring disorders that may require a dual diagnosis program.

A mental health assessment will be performed for an appropriate diagnosis using guidelines outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5).

Psychotherapy

Psychotherapy, including evidence-based therapies like Dialectical Behavior Therapy (DBT) and Cognitive Behavioral Therapy (CBT), can be a helpful for managing personality disorders.

Talk therapy with a psychiatrist or psychologist aims to reduce immediate distress, enhance understanding of internal issues, decrease unhealthy behavior, and modify problematic personality traits.

Dialectical Behavior Therapy (DBT)

Dialectical Behavior Therapy is a form of psychotherapy that combines elements of cognitive-behavioral therapy with mindfulness techniques. It is commonly used to treat individuals with borderline personality disorder (BPD) and other personality disorders characterized by emotional dysregulation and self-destructive behaviors.

Cognitive Behavioral Therapy (CBT)

Cognitive Behavioral Therapy is another of psychotherapy that focuses on identifying and modifying unhealthy thought patterns and behaviors. It can be effective for treating various types of personality disorders, such as histrionic personality disorder.

Medications

Although there are no medications specifically designed to treat personality disorders, certain medications like antidepressants, anti-anxiety drugs, or mood stabilizers may be prescribed to address specific symptoms in some cases.

Each of the types of personality disorders is unique, with the possibility of some overlap within each cluster.

The effectiveness of personality disorder treatment will be dependent on the type, severity, and willingness of the individual to accept that he or she has a problem and is willing to seek help for managing the condition.
