It is widely known comorbid Bulimia Nervosa (BN) with Borderline personality disorders (BPD). This is associated with worse prognosis and resistance to pharmacological and psychotherapeutic treatments. In integrated treatment, both disorders are addressed, not being frequent psychotherapy groups that address only the personality traits. Some studies have proposed the brain basis of psychodrama intervention in both pathologies.

To highlight the clinical effectiveness of adding a nonverbal orientation (psychodrama) to the treatment of BN patients; to specifically address personality traits, by presenting a clinical case. We rely on studies.

Clinical case: 42-year-old woman patient with BN (DSM-5) severe degree, BITE: Symptoms scale = 28; S. Severity = 13; and BPD (7 DSM-V); MCMI-III: BPD = 115 She is incorporated into a day hospital with integrated and multidisciplinary approach: psychotropic drugs, individual, group and family psychotherapy. This patient is added to an open psychodrama group; where he works exclusively personality pathology, during one year.

Improvement was observed in BN (she switched to intermediate grade); BITE: Symptom scale = 23, S. Severity = 8; also improves BPD criteria of DSM-V = 4 (minimum = 5) MCMI-III: BPD = 104.

(1) Psychodrama psychotherapy groups to treat Bulimia and BPD could provide an added clinical improvement in both pathologies.

(2) Insufficient RCTs compared to other models of psychotherapy (mentalizing, interpersonal, dialectical behavior) do not allow to speak even scientific evidence of psychodrama.
