NARCISSISTIC PERSONALITY DISORDER: A REVIEW OF THE LITERATURE ON THE NEUROBIOLOGICAL FACTORS, DIAGNOSIS AND TREATMENT INVOLVED

Abstract

Introduction: Narcissistic Personality Disorder (NPD) is a complex psychiatric condition that has received increasing attention due to its clinical relevance and impact on interpersonal relationships and social functioning. Objetctive: This literature review aims to explore the neurobiological factors, diagnosis and treatment of NPD. Methods: A bibliographic review of the scientific literature was carried out using databases such as PubMed, Web of Science, Scopus and Google Scholar. The inclusion criteria were studies published from 2009 to 2024, in English, Portuguese or Spanish, which addressed neurobiological aspects, diagnosis, treatment or future perspectives of TPN. Results and Discussion: The results of the review highlight the importance of neurobiological factors in the etiology of TPN, the complexity of differential diagnosis and the challenges in treatment, including patients' resistance to change. Therapeutic strategies such as Cognitive-Behavioral Therapy (CBT) and neuromodulation were discussed as effective options, but they require adaptation to patients' individual needs. Conclusion: The literature review provides a comprehensive overview of TPN, emphasizing the continued need for advances in the understanding and management of this condition. Future prospects include longitudinal research, the development of personalized therapeutic approaches and further neurobiological studies to improve the diagnosis and treatment of TPN.
