Brain stimulation study reveals empathy wiring in borderline personality disorder
NCT ID NCT06702215
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at how the brain's 'mirror system' for touch works in people with borderline personality disorder (BPD). Researchers used a non-invasive brain stimulation technique called TMS to temporarily change brain activity while participants watched a hand being touched. The goal was to understand differences in empathy-related brain wiring. 71 people took part, including those with BPD and healthy volunteers.

Inclusion Criteria: * All participants: right handedness (Edinburgh Handedness Inventory; Oldfield, 1971) * Patients group: clinical diagnosis of BPD. The severity of the symptoms will be assessed by means of the Zanarini rating scale for BPD (ZAN-BPD, Zanarini, 2003) and the Symptoms Check-list 90 Revised (SCL-90-R, Derogatis, 1994). Depressive symptoms will be evaluated with the Beck Depression Inventory II (BDI-II, Beck, 1988), impulsiveness with the Barratt Impulsiveness Scale (BIS, Patton, Stanford, \& Barratt, 1995), and alexithymia with the Toronto Alexithymia Scale (TAS-20, Bagby, Taylor, \& Parker, 1994). Moreover, interpersonal functioning will be evaluated with the Interpersonal Problems (IIP, Pilkonis, Kim, Proietti, \& Barkham, 1996), and attachment style will be assessed with the Attachment Style Questionnaire (Feeney, Noller, \& Hanrahan, 1994). Finally, the Childhood Trauma Questionnaire (CTQ; Bernstein \& Fink, 1998) will be administered for the assessment of traumatic experiences, and the Inventory of statements about self-injury (ISAS, Klonsky \& Glenn, 2009) for the evaluation of self-harm. Exclusion Criteria: * All participants: Contraindication to TMS (Rossi et al., 2021) * All participants: Anamnesis or evidence of any central nervous system alteration * Patients group: Comorbidity with schizophrenia and other psychotic disorders, according to DSM-5, and in case of unstable pharmacological therapy
