Borderline Personality Disorder With Atypical Traits in a 30-Year-Old Female: A Case Report

Area of Science:

• Psychiatry
• Clinical Psychology
• Personality Disorders

Background:

• Borderline Personality Disorder (BPD) is a complex mental health condition characterized by emotional instability, impulsivity, and disturbed interpersonal relationships.
• Previous literature has identified various subtypes of BPD, including a high-functioning internalizing subtype, though such presentations remain less understood.
• This study examines an unusual case of BPD in a patient with a history of childhood trauma and Post-Traumatic Stress Disorder (PTSD).

Observation:

• The patient, a 30-year-old female with a history of childhood molestation and trauma, presented with anxiety, depression, and guilt related to alcohol use relapse.
• During hospitalization, a diagnosis of BPD was established through psychiatric examination, clinical interviews, and a comprehensive review of her history.
• Despite exhibiting some typical BPD traits like relationship instability, the patient demonstrated atypical features.

Findings:

• Atypical findings included mature defense mechanisms (sublimation, altruism), high occupational functioning, and strong maternal caregiving.
• Notably, the patient had no history of self-harm, a common characteristic in BPD.
• These unique traits led to the characterization of her presentation as a high-functioning internalizing subtype of BPD.

Implications:

• This case highlights the heterogeneity within BPD presentations and the importance of considering less typical manifestations.
• Recognizing the high-functioning internalizing subtype of BPD can improve diagnostic accuracy and tailor treatment strategies.
• Further research into diverse BPD subtypes is crucial for advancing our understanding and clinical management of this disorder.
