Borderline personality disorder and auditory verbal hallucinations.

Abstract

Auditory verbal hallucinations (AVH) frequently co-occur with borderline personality disorder (BPD) and can lead to misdiagnosis with schizophrenia (SCZ) or other primary psychotic disorders. Misdiagnosis is more common when AVH meet criteria for Schneiderian first rank symptoms (FRS). This paper's objective is to improve diagnostic accuracy by outlining particular clinical features that can assist the distinction between BPD and psychotic disorders in these cases. The overall clinical presentation when AVH occur in BPD can assist in determining a primary diagnosis of BPD when frank psychotic disorder is absent. AVH in BPD cannot be distinguished phenomenologically from AVH in SCZ. Clinical experience and increasing research suggest that AVH in BPD are often dissociative in origin and highly correlated with the presence of FRS, elevated levels of dissociation and a history of childhood trauma. When AVH occur in BPD in the absence of co-occurring psychotic disorder, formal thought disorder is usually absent, negative symptoms minimal or absent, bizarre symptoms absent, affect reactive and the patient retains sociability. Psychotropic medication may be less effective for the AVH in these cases, while they may improve or remit during psychotherapy for BPD.
