Insights into Narcissistic Personality Disorder: A Narrative Review with Cultural and Biological Insights from Pakistan

Narcissistic Personality Disorder (NPD) is a heterogeneous and complicated personality disorder that is marked by grandiosity, admiration, and a lack of empathy. The purpose of this narrative review was to conduct a synthesis of literature on the etiological, diagnostic, genetic, and cultural aspects of NPD in the Pakistani sociocultural setting. The PubMed, PsycINFO, Scopus, and Google Scholar databases were used to conduct a narrative literature review. A search was conducted on peer-reviewed articles that were published from 2019 to 2024 with the keyword’s narcissistic personality disorder, genetics, epigenetics, diagnosis, culture, and Pakistan. The relevant studies were applied to such topics as etiology, diagnosis, and cultural influences. The cultural values where collectivism is the dominant trait in Pakistan can affect the manifestation and perception of narcissistic features, which, in most cases, do not lead to the expression of overt grandiosity as in individualistic cultures, and that, consequently, complicates the clinical diagnosis. Despite the implicated role of dopaminergic and serotonergic pathways in the causes of NPD, such as DRD4, 5-HTTLPR, and COMT, no concrete genetic biomarkers have been defined. The emergent data point to the influence of the epigenetic processes, according to which the early-life adversity, trauma, and sociocultural factors regulate the expression of genes without changes in the sequences. It is important to have an insight into how genetic vulnerability and cultural situation relate to help diagnose and intervene appropriately in the treatment of NPD in Pakistan. It may enhance psychosocial outcomes and therapeutic interventions in the framework of culturally sensitive assessment models and biologically informed research
