Abstract

The symptomatic overlap between borderline personality disorder (BPD) and bipolar disorder (BD) is a topic of scientific and academic debates. Emotional dysregulation and impulsivity are common features of both disorders. Several studies have shown that both BPD and BD lie on a spectrum; others have suggested that they are separate entities that coexist.  BPD is characterized by impulsive and dangerous behaviors such as driving recklessly, inappropriate sexual behavior, eating disorders, and substance abuse. BD, during a manic episode, is known for their impulsive and risk-taking behavior like hypersexuality, excessive spending, and substance abuse.  The current literature review aims to provide an overview of the impact of impulsivity and emotional dysregulation on comorbid bipolar disorder and borderline personality disorder. Our study results showed that patients with comorbid BPD and BD struggle with impulsive actions and have difficulty controlling their emotions. They are also highly susceptible to anxiety disorders like obsessive-compulsive disorder (OCD), post-traumatic stress disorder (PTSD), and somatoform disorders. Patients with comorbid BPD and BD struggle with severe psychosocial morbidity and an increased risk of suicide. In patients with only one disease, misdiagnosis is a common phenomenon due to the overlapping symptoms of BPD and BD.
