How To Diagnose Narcissistic Personality Disorder & What Is The Best Medicine For It?

Personality disorders originate in early childhood, and both the environmental and genetic backgrounds are involved in their etiopathologies. It is characterized by an enduring pattern of inner experience & attitude that deviates markedly from the expectations of people around or the related culture(1). Patients have pervasive & long-standing traits which affect their perception, cognition, emotion, and behavior, as well as their ability to function in interpersonal or other social roles.

Three Clusters Of Personality Disorders

According to the “Diagnostic & Statistical Manual of Mental Disorders” (fifth edition), personality disorders are divided into three clusters. They are

  1. Type A cluster includes schizoid, paranoid and schizotypal types,
  2. Type B cluster includes borderline, antisocial, narcissistic, histrionic, and
  3. Type C cluster includes dependent, avoidant, & obsessive-compulsive.

A research analysis studied by the World Health Organization (WHO) has revealed that the prevalence assessments are 6.1% for any personality disorder; and 3.6%, 1.5%, and 2.7% for type A, B, and C cluster correspondingly(2).

A narcissistic personality disorder is a distinct personality disorder, falls in type B cluster. It describes the person character who behaves as grandiosity (impressiveness in behavior or fantasy). They generally tend to recreate appreciation and sometimes they do not understand(3). Narcissistic personality disorder is estimated to affect 7.7% of males and 4.8% of females in the general population(4) and it remains one of the least studied personality disorders.

How To Diagnose Narcissistic Personality Disorder?

Narcissistic personality disorder needs to be diagnosed by a professional. Commonly, the treatment involves talk therapy i.e. scientifically it is known as “item response theory”. According to the theory of psychological measurement, item response theory is a standard form of design and investigation which involves questionnaires. The answer from the individuals helps the professionals to judge their character and attitudes(5). This design can easily predict the participant sufferings and symptoms which further makes it easier to put them at a specific degree of narcissistic personality severity(6).

Application of item response theory methods is emerging in the evaluation of DSM (Diagnostic & Statistical Manual of Mental Disorders ) criteria, including criteria for alcohol dependence, nicotine dependence, amphetamine, cocaine, and prescription drugs, unipolar and bipolar depression, mania, personality disorders, post-traumatic stress disorder, bulimia and attention-deficit/hyperactivity disorder(7).

Procedure For Evaluation Of Narcissistic Personality Disorder

The scientific team of psychiatrists interviews and evaluates the patients/participants metacognition levels. Patients/ Participants are asked to write the questionnaire which brings about their particular degree of symptoms associated suffering over the past 2 weeks. It has a scale ranging from 1 to 4, which signifies 1 as not at all and 4 as very much. The questionnaires/analysis apart from symptoms agenda, it also involves Alexithymia Scale (Toronto Alexithymia Scale -a measure of deficiency in understanding, processing, or describing emotions), structured clinical interview for personality disorder diagnosis, and Metacognition Assessment Interview. Metacognition Assessment Interview specific questions will be based upon four metacognitive sub-functions such as Monitoring, Integration, Differentiation, and Decentration(7).

Neuroimaging Findings

The neuroimaging techniques such as computerized tomography (CT), magnetic resonance imaging (MRI), functional MRI (fMRI), single-photon emission CT (SPECT), and positron emission tomography (PET) can reveal the volumetric abnormalities in regions and their ratio to the whole brain in personality disorders. The advent of MRI has truly revolutionized the field of neuroimaging(8).

What Is The Best Medicine For Narcissistic Personality Disorder?

Till now there is no best medicine prescribed for treating narcissistic personality disorder, because narcissistic personality disorder does not respond to chemotherapy(10).

But, psychotherapist suggests drugs which involve antidepressants and antianxiety which could support the alleviation of symptoms. Talk therapy or psychotherapy i.e. consultation with a psychiatrist is the best approach for this personality disorder.

Family Therapy Or Group Therapy

Family therapy or group therapy is the best alternative for affected individuals to recover from narcissistic personality disorder. This must be kept for prolong period which would be effective for sufferers to realize their damaged lives. However, this group/family or psychotherapy must be approached with loving care and patients do not push too fast.

Cognitive Behavioral Therapy

The most vibrant therapy for narcissistic personality disorder is cognitive behavioral therapy(11). It supports to improve mental health by changing their thought and behave. It is a psycho-social intervention, thought-provoking, improves emotive, and manage the problems. Today, cognitive behavioral therapy is universally practiced by the therapist to alleviate various personality disorders such as paranoia, alcohol/substance addictions, depression, and anxiety.

Psychoanalytic Psychotherapy

Scientifically, it is called as insight-oriented therapy, which focusses on inner unconscious content of patients and eases their psychic tension (13). The main objectives of psychodynamic therapy or psychoanalytic psychotherapy for narcissistic personality disorder are to create person cognizance and realize their past and present behavior.

Schema-Focused Therapy

Schema therapy is focused on patients who are unsuccessful to respond after having been through other therapies. A schema is defined as an organized pattern of thought and behavior. This therapy is to help patients meet their basic emotional needs. It is a long-term process which requires 18-36 month of therapy and it possesses a comprehensive variety of methods, such as social interaction, psychoanalytical therapy, experiential and interpersonal strategies(12).

Skills-Based Interventions

Skills training interventions are focused mainly on borderline personality disorder by supporting coaching, demonstrating model, and providing opportunities for practice(14). It is effective to decrease the self-damaging manners associated with a borderline personality disorder.

Challenges In Therapy

It is a difficult process for health professionals to treat narcissistic personality disorder affected individuals as they will not cooperate naturally during the early stages of the disorder. They resist the therapy and it is the psychiatrist’s duty to make the individuals co-operate for the treatment. Most of the individuals are treated by the residential mental health treatment facility which is effective for narcissism as therapy is regular and intensive(15). It is supportive for advanced disorder and helpful process to reduce the symptoms. It is most challenging as sufferers feel unstable and mood disorders are common.

Conclusion

Narcissistic personality disorder is a problem in which a person has an inflated sense of self-importance. Treatment can be supportive, but this condition cannot be cured completely. The disorder needs to be diagnosed by a professional clinical team of psychologists and psychiatrists based on consultation or talk therapy. Talk therapy similar to item response theory procedures is an initial stage in the assessment of DSM (Diagnostic and Statistical Manual of Mental Disorders) criteria for any psychiatric disorders.

Narcissistic personality disorder can be diagnosed by Metacognition Assessment Interview, Toronto Alexithymia Scale, and levels of a symptom of patients. The neuroimaging techniques can reveal the abnormalities in the regions of the brain in personality disorders.

There is no specific medicine for narcissism and drugs such as antidepressants and antianxiety supports the reduction of symptoms. Family therapy or group therapy, cognitive behavioral therapy, insight-oriented therapy, schema-focused therapy, and skills-based interventions therapy are the best approach for this personality disorder.
