Narcissistic Personality Disorder


Narcissistic personality disorder (NPD) is a complex and often misunderstood psychological condition usually characterised by deep-seated feelings of grandiosity, a craving for admiration and a lack of empathy toward others. Often overshadowed by its portrayal in popular culture, true NPD goes beyond mere self-centeredness or vanity, and it is crucial to understand that NPD is not a condition someone chooses. NPD can profoundly affect individuals’ lives and the lives of those around them, so destigmatising the condition and making effective treatment available for those who need it is crucial.

Through expert understanding and years of experience, UKAT London Clinic aims to provide compassionate and effective avenues for NPD diagnosis, treatment and critical ongoing support.

What is narcissistic personality disorder?

Narcissistic personality disorder is a mental health condition that manifests in a pervasive pattern of:

  • Grandiosity (either in fantasy or actual behaviour)
  • An irrational and persistent need for admiration
  • A notable lack of empathy towards others

The term “narcissism” finds its origins in Greek mythology. It is derived from the tale of Narcissus, a young man renowned for his beauty, who fell in love with his reflection in a pool of water, not realising it was merely an image. While “narcissist” is frequently used colloquially to describe someone who seems overly self-involved, clinical NPD is far more complex. It is not about the occasional self-centred action or moment of vanity; instead, it represents chronic patterns that deeply affect an individual’s thinking, functioning and interaction with the world.

Narcissistic personality disorder diagnosis

The DSM-5 sets forth specific criteria for diagnosing NPD. According to the DSM-5, an individual must exhibit at least five of the following nine criteria:

  • A grandiose sense of self-importance


  • Preoccupation with fantasies of unlimited success, power, brilliance, beauty or ideal love


  • Belief in being special or unique


  • Need for excessive admiration


  • Sense of entitlement


  • Interpersonally exploitative behaviour


  • Lack of empathy


  • Envy of others or the belief that others are envious of them


  • Demonstration of arrogant behaviours or attitudes


These patterns of behaviour typically begin by early adulthood and for a diagnosis of NPD, they must be consistent across situations and not better explained by another mental disorder, the effects of a substance or another medical condition.

The spectrum of narcissistic personality disorder


Much like many other psychological conditions, NPD is not a one-size-fits-all diagnosis, and manifestations can vary significantly in intensity and presentation from one individual to another. This is why NPD is often conceptualised as a spectrum.

On one end of the spectrum, individuals may display traits or behaviours that can be considered narcissistic but may not be intense or pervasive enough to warrant a clinical diagnosis of NPD. These traits may include occasional bouts of self-centeredness, a need for validation or overconfidence in specific situations.

Moving further along the spectrum, we encounter what can be termed “clinical” or “pathological narcissism.” Here, the symptoms are more pronounced, consistent and disruptive.The characteristics that define NPD, such as a lack of empathy, a deep need for admiration and grandiose fantasies, are evident and significantly impact an individual’s daily life.

An individual’s position on the narcissism spectrum might not be static throughout their life. External factors, personal experiences or interventions like therapy can influence the intensity and presentation of narcissistic traits. For instance, significant life events or losses might amplify symptoms, while targeted therapy may reduce their severity.

What causes narcissistic personality disorder?

Narcissistic personality disorder results from a complex interplay between genetic, environmental and psychological factors. While the precise cause remains elusive, current research suggests several potential contributing elements:

Genetic predisposition

Family studies suggest a hereditary component, while no specific “NPD gene” has been identified. This means that individuals with a first-degree relative diagnosed with NPD may have a higher likelihood of developing the condition themselves.

Brain structure and function

Emerging research using brain imaging techniques like MRI has shown differences in the brain structures related to emotion, empathy and impulse control in people with NPD. However, it is not clear if these differences are a cause or result of the disorder.

Environmental and social influences

Childhood experiences play a pivotal role in personality development. Certain environmental factors may contribute to or exacerbate narcissistic tendencies, including:

  • Mismatched parenting: This could involve excessive pampering, over-praising or, conversely, excessive criticism or neglect. Such parenting styles may foster an unstable self-image, leading to grandiosity as a defence mechanism.
  • Trauma or abuse: Early life traumas, whether physical, emotional or sexual, can influence personality development. Some individuals may develop narcissistic traits as a protective mechanism against deep-seated feelings of worthlessness or vulnerability that trauma causes.
  • Cultural and societal factors: Living in a culture that promotes individualism, competition and “standing out” could also contribute to narcissistic traits. Additionally, the rise of social media and the emphasis on “personal brands” could potentially amplify these tendencies.

Psychological factors

Some theories suggest that NPD may develop as a response to an inner sense of fragility or low self-esteem. Individuals may project an image of superiority and invulnerability to protect themselves from feelings of inadequacy. Over time, this defensive mechanism becomes deeply ingrained, leading to the consistent patterns of behaviour associated with NPD.

Coexisting conditions and overlaps

Narcissistic personality disorder often coexists with other personality disorders or mental health conditions, further complicating diagnosis and treatment. Addressing only narcissistic symptoms without recognising a coexisting condition can be less effective and potentially overlook significant aspects of an individual’s well-being. That is why diagnosing co-occurring disorders alongside NPD is so important in formal assessments. Common co-occurring conditions and overlaps with NPD include:

Borderline personality disorder (BPD): Individuals with BPD might exhibit intense mood swings, fear of abandonment and unstable relationships. Some traits, like impulsivity and a fluctuating sense of self-worth, can often overlap with NPD.


Antisocial personality disorder (ASPD): ASPD is marked by a long-term pattern of disregarding or violating the rights of others. It is not uncommon for someone with ASPD to also display narcissistic tendencies like a lack of empathy or a grandiose sense of self-importance.


Autism spectrum disorder (ASD): While NPD and ASD are distinct conditions, there can be some overlapping behaviours, such as challenges in understanding social cues or empathy. However, while an individual with NPD may lack empathy due to an excessive focus on their own needs, an individual with ASD may struggle to understand or interpret others’ emotions.


Anxiety and depression: The fragile self-esteem often underlying the outward ultra-confidence of NPD can make individuals with the disorder vulnerable to anxiety and depression. Feeling criticised or falling short of their high standards can trigger episodes of deep sadness or heightened anxiousness, which can take a major toll.


Substance use disorders: In some cases, individuals with NPD might turn to drugs or alcohol to cope with internal discord or amplify their feelings of grandiosity. This can lead to a coexisting substance use disorder that demands its specific treatment approach while also considering NOD symptoms.


Diagnosing narcissistic personality disorder

Making a definitive diagnosis of narcissistic personality disorder requires a comprehensive evaluation. It’s essential to approach the diagnosis with sensitivity and care, understanding that it’s not about labelling but about paving the way for effective treatment and improved well-being.

The primary step involves a detailed clinical interview conducted by a psychiatrist or psychologist. This interview focuses on the patient’s life history, their patterns of behaviour and the challenges they face in daily functioning. They may be asked about their relationships, work history and any episodes of distress or instability.

Healthcare professionals will also use the DSM-V criteria to determine if an individual’s symptoms align with NPD. As mentioned, a diagnosis typically requires that an individual meets at least five of the nine criteria and rules out other possible causes for the symptoms.

Sometimes, the individual may not recognise their symptoms or may perceive them differently than those around them. In such cases, close family or friends’ input can offer invaluable insights into the individual’s behaviour and thinking patterns. Once these assessments have been made, an effective treatment plan can be formulated.

Narcissistic personality disorder treatment

Navigating the intricacies of narcissistic personality disorder necessitates a tailored and holistic approach. At UKAT London Clinic, we are committed to offering bespoke evidence-based interventions, recognising the unique needs of each individual. The primary goal of treatment is to help individuals develop a more stable and realistic self-image, foster empathy and build healthier relationships. Effective treatment programmes often involve:


Psychotherapy, or talk therapy, is the primary treatment method for narcissistic personality disorder. Different therapeutic approaches include:

  • Cognitive behavioural therapy (CBT): This helps individuals recognise and change maladaptive thinking and behaviour patterns. It can assist in reducing feelings of entitlement, seeking constant admiration and responding negatively to criticism.
  • Dialectical behavioural therapy (DBT): DBT is a widely recognised and effective form of psychotherapy that combines cognitive-behavioural techniques with mindfulness principles to help individuals better manage their emotions and improve their mental well-being.
  • Group therapy: Group therapy offers a space where individuals can interact with others under the guidance of a trained therapist. It can benefit those with NPD to see reflections of their behaviour in others, while the group setting can promote understanding and empathy.

Holistic and lifestyle strategies

Alongside formal treatment, several holistic lifestyle strategies can also be beneficial. These include:

  • NPD education: Understanding NPD and how it affects themselves and others can help individuals recognise and address their behaviours.
  • Support groups: Joining a support group or connecting with others with the same condition can offer validation and shared experiences.
  • Stress reduction: Techniques such as meditation, deep breathing exercises and yoga can help manage stress, often exacerbating NPD symptoms.
  • Mental health support: NPD can cause a huge amount of mental strain, especially when it co-occurs with other conditions. Mental health support during and after treatment is crucial for effective results.

Medication for NPD

While no specific drug exists to treat NPD, certain medications may be prescribed to address specific symptoms or conditions that co-occur with the disorder. For example:

  • Antidepressants may help manage symptoms of depression or mood swings.
  • Antipsychotic medications might be beneficial if the individual shows symptoms of distortion in thinking.
  • Mood stabilisers can help even out mood swings or reduce impulsivity.

Frequently asked questions

Why does narcissistic personality disorder fall on a spectrum?
Narcissistic personality disorder falls on a spectrum, encompassing many symptoms and severities. Not everyone with NPD will exhibit the same behaviours or to the same extent. Some may have milder manifestations, while others display more severe and pervasive patterns that significantly affect their daily lives. This spectrum approach acknowledges the variability in presentation and ensures a more nuanced understanding and tailored treatment.
Is narcissistic personality disorder genetic?
There is evidence to suggest a genetic component to narcissistic personality disorder. Family studies have indicated that if a family member, particularly a first-degree relative, has NPD, there is a higher likelihood of other family members developing it. However, while genetics can predispose someone to certain traits or behaviours, environmental factors and individual experiences play a significant role in the actual development and manifestation of the disorder.
