Psychosis in Borderline Personality Disorder: A Neglected Clinical Phenomenon

Area of Science:

• Psychiatry
• Clinical Psychology
• Psychoanalysis

Background:

• Psychotic symptoms are prevalent in borderline personality disorder (BPD), affecting up to 60% of patients.
• Contemporary BPD diagnostics often minimize reality testing impairments, focusing instead on affective instability and interpersonal issues.
• Historical perspectives link BPD to schizophrenia-like conditions, suggesting a deeper connection to psychotic phenomena.

Purpose of the Study:

• To review the historical context and phenomenology of psychotic symptoms in BPD.
• To propose a theoretical framework for understanding these symptoms within object-relations theory.
• To advocate for increased clinical recognition and theoretically informed interventions for psychotic symptoms in BPD.

Main Methods:

• Literature review of historical roots and phenomenology of BPD.
• Theoretical analysis drawing on psychoanalytic object-relations theory (Kernberg, Gunderson).
• Argumentative synthesis to support the proposed theoretical framework.

Main Results:

• Psychotic symptoms in BPD, including hallucinations and delusions, are proposed to serve an object-restitutive function.
• These symptoms are suggested to maintain internal relational continuity during psychic disintegration.
• The study posits that psychotic symptoms are core features, not incidental aspects, of BPD.

Conclusions:

• Psychotic symptoms represent a neglected but crucial dimension of borderline personality disorder.
• Enhanced clinical recognition and psychoanalytically informed treatments are necessary.
• Addressing reality testing impairments is vital for comprehensive BPD management.
