To clarify the nature of delusional and hallucinatory symptoms in borderline personality disorder (BPD), the authors investigated five patients with BPD who developed those symptoms, and discussed their duration, recurrence, types of variants and relation to the situation. The duration of these symptoms tended to vary widely, although six of 11 episodes lasted more than 7 days. Episodes tended to recur in all patients two or three times. Each episode could be classified into three types of delusions and hallucinations, such as delusions without hallucinations, complicated delusion and hallucination, and hallucinations without delusion. Delusions without hallucination occurred a total of four times in two patients and had a tendency to occur when the patient confronted personal adversities. They projected their feelings directly toward the person concerned. A complicated delusion and hallucination was observed three times in two patients. This type of symptom also tended to occur at the time of interpersonal problems but the patient's attitude was more passive. Hallucination without delusion occurred a total of four times in three patients. This symptom tended to occur when the patient avoided an interpersonal relationship. In this case the patients isolated themselves from others and withdrew.
