Hallucinations and delusions are common in borderline personality disorder (BPD) and often resemble those in schizophrenia spectrum disorders. In a study of 89 adults, 81% of those with BPD reported visual and tactile hallucinations, 75% reported olfactory hallucinations, and 94% experienced delusions. Comparing BPD with and without voices showed no significant differences in nonpsychotic psychopathology. Hallucinations in BPD were similar to those in schizophrenia, though the BPD group had higher rates of paranoia and delusions of guilt. Multisensory hallucinations and delusions in BPD warrant clinical attention.
