Personality Disorders: Diagnostic Challenges, Clinical Features, and Contemporary Therapeutic Approaches

Abstract

Personality disorders (PDs) are enduring and inflexible patterns of behavior, cognition, and inner experience that deviate markedly from cultural expectations and cause significant distress or impairment. This article provides a comprehensive review of the classification, epidemiology, etiology, clinical features, diagnosis, and treatment of personality disorders, emphasizing both traditional categorical frameworks (e.g., DSM-5) and emerging dimensional models (e.g., ICD-11 and AMPD). The review highlights evidence-based therapeutic modalities, particularly psychodynamic and cognitive-behavioral interventions such as Dialectical Behavior Therapy, Mentalization-Based Therapy, and Schema Therapy. It also discusses pharmacological strategies as adjunctive tools. Special attention is given to the social, cultural, and ethical considerations in diagnosing and managing PDs, including issues of stigma, cultural bias, gender disparities, and barriers to care. Through a biopsychosocial lens, the article argues that personality disorders are treatable, dynamic conditions that benefit from early intervention, interdisciplinary collaboration, and culturally sensitive, person-centered care. The paper concludes with a call for improved access to mental health services and a shift toward non-pathologizing, recovery-oriented approaches.
