Personality disorders (PDs) are mental disorders with extreme personality traits that interfere with a person’s everyday life. Although personality disorders are long-term mental conditions, their symptoms can be effectively managed with therapy, medication, and self-help strategies.

What Is A Personality Disorder?

Personality disorders occur when certain troubling personality traits make it difficult for a person to function normally. They majorly involve maladaptive and chronic patterns of cognition, behavior, and mood. These conditions often last for a lifetime, creating difficulties in work, social life, and personal life.

The types, causes, and symptoms of personality disorders are overarching and research 1 is still trying to understand the different personality disorders and their well-categorized diagnosis and treatment. Personality disorders are common but long-term and complex. They are frequently associated 2 with an inferior quality of life (QoL), poor health, and premature mortality. These mental conditions can be distressing for the suffering individual, the people around them, as well as society as a whole. 

People suffering from personality disorders may experience emotional dysfunction and perceive reality in distorted ways. They may also suffer from low self-esteem and self-confidence, and project their insecurities on others. These factors affect their normal emotional responses and conduct. They tend to experience extreme negative emotions like:

  • Suspicion
  • Narcissism
  • Mistrust
  • Impulsivity
  • Malice, etc.

This contributes to their extremely poor social lives, characterized by unstable and toxic relationships. If left untreated, personality disorders can severely impact a person’s personal and professional relationships and social functioning.

However, they can be addressed in the long run with timely diagnosis, the right treatment, and a disciplined therapeutic regime. Luckily, certain personality disorders phase out as the individual ages. The symptoms become less severe and debilitating with age.

Types Of Personality Disorders

In the DSM-5, the personality disorder types are divided into 3 clusters—depending on the symptoms and the severity of the personality disorders. Provided below is a list of personality disorders, with the major cluster groups and their sub-categories:

1. Cluster A

Personality disorders in cluster A are disorders defined by odd or eccentric behavior. This group of disorders is greatly associated with schizophrenia and it shares similar schizoaffective symptoms like:

  • Distorted reality
  • Hallucinations
  • Eccentric behavior
  • Difficulty in maintaining relationships
  • Experiencing paranoia and other irrational fears
  • Vulnerability to psychosis and schizoaffective disorders

The three types 6 of personality disorders in cluster A include:

I. Paranoid personality disorder (PPD)

People suffering from paranoid personality disorders usually experience feelings of extreme mistrust and irrational suspicion. They also experience anger over presumed abuse, anxiety over perceived threats, and a heightened sense of fear.

II. Schizoid personality disorder (PD)

People with schizoid PD display odd behavior related to personal detachment, social avoidance, and apathy. They are restricted in their emotional expressions and they tend to avoid intimacy. Mostly, they are characterized by a lack of interpersonal relationships.

III. Schizotypal personality disorder (SPD)

People with schizotypal PD are characterized by odd beliefs, thinking, and speech. The hallmark of SPD is paranoia and its sufferers tend to experience paranoia-related social anxiety.

2. Cluster B

Cluster B 7 personality disorders are characterized by dramatic, impulsive, and extremely emotional behavior. People with these personality disorders are characterized by impulsive, self-destructive, and emotional behavior and incomprehensible social interactions.

The most common personality disorders in cluster B include:

I. Antisocial personality disorder

Dissocial or antisocial PD involves a disregard for social rules and social norms and a lack of empathy for others. People with antisocial PD usually harbor a grandiose self-image and display aggressive and manipulative behavior. Research 7 affirms that they are also the ones with criminal and psychopathic tendencies.

II. Borderline personality disorder (BPD)

Borderline personality disorder (BPD) is a psychiatric disorder in which the person suffers from unstable relationships, a distorted sense of self and reality, and emotional dysfunction.

III. Histrionic personality disorder

Histrionic personality disorder is a psychiatric disorder in which a person displays extremely erratic, emotionally charged, and attention-seeking behavior.

IV. Narcissistic personality disorder (NPD)

People with narcissistic personality disorder (NPD) 8 are characterized by grandiosity, fantasies of unlimited power or importance, and the need for admiration or special treatment. They also display extremely high levels of paranoia and psychopathy.

3. Cluster C

The characteristics of personality disorders in cluster C are anxiety or fear-related. These disorders include:

I. Avoidant personality disorder (AVPD)

Avoidant personality disorder (AVPD) is associated with emotional distress, cognitive impairment, and disability. People with this type of disorder tend to isolate themselves and avoid duties and responsibilities. They are also extremely sensitive to criticism and rejection.

II. Dependent personality disorder

Dependent Personality Disorder (DPD) is a long-term condition 9 that involves pervasive mental and emotional dependence on others. Sufferers rely on other people for comfort, reassurance, advice, and support. They suffer from a chronic fear of abandonment and have trouble making simple everyday decisions.

III. Obsessive-compulsive personality disorder (OCD)

People with OCD or anankastic PD tend to compulsively focus on orderliness and perfectionism. They observe very rigid conformity to rules and are prone to controlling others around them to the point of satisfaction.

What Causes Personality Disorders?

There is no specific reason for the development of personality disorders. However, research 4 attributes the common causes of personality disorders to:

  1. Genetic mechanisms 10 and birth deformities
  2. Traumatic brain injury 11
  3. Personality traits 12 like narcissism, aggression, suspicion, etc. add to the risk of PDs
  4. A history of childhood abuse and trauma
  5. A history of parental abuse, neglect, and abandonment
  6. A family history of mental disorders
  7. Negative developmental experiences 7 (related to war, poverty, etc.)
  8. Certain cultural and societal norms 13
  9. Stress 14 (like workplace demands, bullying, workaholism, etc.)
  10. Major life changes (like the death of a loved one, experiences of relocation, etc.)

How To Diagnose Personality Disorders?

The criteria to diagnose personality disorders have been laid down by psychiatric manuals like ICD and DSM. These disorders can be easily categorized and diagnosed on the basis of their symptoms, severity, and longevity. The process of diagnosing personality disorders 15 usually involves:

  • A physical examination of the patient
  • Interviews with the patients and their families
  • Psychological assessments
  • Differential diagnosis of PD

If it is seen that the concerned patient is suffering from a personality disorder, he/she is advised medication and/or therapy.  An early and timely diagnosis16 of a personality disorder means a better treatment outcome.

A psychologist or psychiatrist makes a differential diagnosis to separate out PD symptoms from similar symptoms associated with other psychiatric disorders like depression, psychosis, schizophrenia, etc. This is done through several personality disorder tests, such as:

  • Standardized Assessment of Personality (SAP) 17
  • Structured Clinical Interview for DSM‐IV Personality Disorders (SCID‐II) 18
  • Computerized Adaptive Test of Personality Disorder (CAT-PD) 19
  • Minnesota Multiphasic Personality Inventory (MMPI) 20, etc.

Treatment For Personality Disorders

Personality disorders are complex and sometimes life-long psychiatric disorders. But these can be effectively managed by a combination of therapies, medications, and healthy self-help strategies.

Social support, as well as community awareness and aid, can go a long way for people recovering from crippling personality disorders. However, in severe cases, treatment for personality disorders involves hospitalization.

1. Therapy

Therapy for personality disorders addresses behavioral and conduct disorders 21, self-harm and suicidal tendencies, and emotional dysfunction. In fact, these are aimed to induce empathy, assertiveness, confidence, and healthy thought processes in people suffering from personality disorders. The common therapies used in treating PDs include:

I. Psychotherapy

Psychotherapy improves the underlying, abnormal, psychological, and biological mechanisms that lead to a disordered personality. It helps the patients reorganize their thought processes and correct their behavior 22. Popularly, cognitive behavioral therapy 21 (CBT) and dialectic behavioral therapy (DBT) are used to treat personality disorders.

II. Mentalization-based treatment (MBT)

Mentalization-based treatment 23 is used to correct the reduced capacities to mentalize or self-reflect in people with PDs. It helps address problems related to emotional regulation and impulsivity, especially in the context of interpersonal interactions.

III. Milieu therapy

Milieu therapy 24 aims to address issues related to maladjustment in people suffering from personality disorders. It helps to make substantial changes in a patient’s immediate life circumstances and environment, reduce conflict and boost life satisfaction, and improve his/her quality of life.

IV. Family therapy

Family therapy 25 aims to reduce conflict and ill feelings between people suffering from PDs and their close ones, especially family and friends. It addresses the broken or unsuccessful interpersonal relationships that characterize PDs. 

V. Group therapy

Group therapy 26 involves patients with PDs joining groups of people suffering from similar personality disorders and resolving their issues by mutual understanding and empathy. It is the cornerstone of community support when it comes to recovery from crippling personality disorders.

2. Medication

Currently, there are no prescribed medications specifically for personality disorders. A 2018 study 7 elaborates that the current pharmacological treatment for personality disorders assumes that psychotropic drugs can treat the personality disorder symptoms specifically caused by biochemical abnormalities.

But, because of the diversity of symptoms and causes, medical practitioners have increasingly relied on psychiatric polypharmacy to address the symptoms of personality disorders.

For instance, in order to eliminate specific symptoms of comorbid psychiatric disorders in personality disorders (say borderline personality disorder), a combination 27 of antidepressants, antipsychotics, or mood-stabilizing drugs is administered. As heavy use of medication comes with risks of side effects, it is widely recommended that such a pharmacological treatment approach should come with close and continuous clinical supervision of medical specialists.

Coping With Personality Disorders

Self Help Tips To Cope With Personality Disorders.

For people living with personality disorders, certain self-help strategies can help with day-to-day functioning. However, for severe personality disorders, it is always advisable to consult a psychologist or a psychiatrist as the symptoms may be unmanageable by the individual.

Consider the following self-strategies to cope with personality disorders:

  • Educate yourself about personality disorders and how to address them
  • Practice self-care by eating nutritious food, getting adequate sleep and exercise, etc.
  • Avoid substance use (like alcohol, drugs, tobacco, etc.)
  • Avail relaxation and stress management techniques like yoga, meditation, etc.
  • Develop healthy hobbies that help you grow or practice gratitude (like journaling, gardening, hiking, etc.)
  • Communicate with your loved ones and spend time with them
  • Join a support group and develop a strong support system
  • Maintain a disciplined regime of therapy and medication
  • Identify your self-harm triggers and avail emergency mental health services, if needed


Personality disorders are perhaps some of the long-lasting, misunderstood, and crippling psychiatric disorders. If left untreated, these can go on to negatively impact a person’s quality of life, career, interpersonal relationships, and social functioning. However, they can be easily managed with therapy, medication, and self-help coping strategies, as well as by harboring faith and patience in the healing process.
