About this study

Official title: Effect of Repetitive Transcranial Magnetic Stimulation Versus Theta Burst Stimulation on Impulsivity, Emotional Dysregulation, and Non-Suicidal Self-Injury in a Sample of Patients With Borderline Personality Disorder: A Randomized Controlled Trial

the goal of this randomized clinical trial is to evaluate the therapeutic efficacy of repetitive transcranial magnetic stimulation (rTMS) and intermittent theta-burst stimulation (iTBS) in patients with borderline personality disorder (BPD). The study aims to assess whether these brain stimulation techniques can reduce symptoms of emotional dysregulation, impulsivity, and non-suicidal self-injury.

The main questions it aims to answer are:

Does high-frequency rTMS over the left dorsolateral prefrontal cortex (DLPFC) improve emotional dysregulation, impulsivity, and non-suicidal self-injury in patients with BPD? Does intermittent theta-burst stimulation (iTBS) over the left DLPFC produce similar therapeutic effects? How does the efficacy of rTMS and iTBS compare to sham stimulation after completing the treatment course?

Participants will be randomly assigned to one of three groups:

  1. High-frequency rTMS group
  2. Intermittent theta-burst stimulation (iTBS) group
  3. Sham stimulation group Each participant will receive 15-20 stimulation sessions over the left DLPFC. Changes in emotional dysregulation, impulsivity, and non-suicidal self-injury symptoms will be evaluated before and after treatment.
Read the detailed description

Borderline Personality Disorder (BPD) is a complex psychiatric condition characterized by emotional dysregulation, impulsivity, and recurrent non-suicidal self-injury (NSSI).

Although psychotherapy and pharmacological interventions remain the mainstay of treatment, many patients continue to experience severe emotional instability and impulsivity. Neuromodulation techniques such as repetitive transcranial magnetic stimulation (rTMS) and theta burst stimulation (TBS) have recently shown promise in modulating fronto-limbic circuits involved in emotion regulation.

This prospective, randomized, double-blind, controlled clinical trial aims to evaluate and compare the therapeutic efficacy of high-frequency rTMS and intermittent theta-burst stimulation (iTBS) applied over the left dorsolateral prefrontal cortex (DLPFC) in patients diagnosed with BPD. The interventions are expected to enhance prefrontal modulation of limbic activity, thereby improving emotional regulation, reducing impulsivity, and decreasing non-suicidal self-injury behaviors.

Participants will be randomly assigned to one of three groups:

Group 1: High-frequency rTMS (5 Hz, 1200 pulses/session, 80-110% RMT, 21 min total) Group 2: Intermittent theta-burst stimulation (iTBS, 50 Hz bursts, 600 pulses/session, 80-120% RMT, 21 min total) Group 3: Sham stimulation (matched duration and sound without magnetic output) All participants will continue their standard therapy for BPD, including weekly Dialectical Behavior Therapy (DBT) sessions during the study. Each participant will receive 20 sessions over 4 weeks (5 sessions per week). Allocation concealment will be ensured using sealed, numbered envelopes prepared by an independent administrator, and both participants and assessors will be blinded to group assignment.

Clinical assessments will include:

Structured Clinical Interview for DSM-IV Axis II Disorders (SCID-II) for BPD diagnosis General Health Questionnaire (GHQ-28) to screen for psychiatric comorbidities Difficulties in Emotion Regulation Scale - Short Form (DERS-16) Barratt Impulsiveness Scale (BIS) Deliberate Self-Harm Inventory (DSHI) Measurements will be taken at baseline (pre-intervention) and after completion of the stimulation sessions (post-intervention).

Safety procedures will follow international TMS safety guidelines (Rossi et al., 2009; Lefaucheur et al., 2020). Adverse effects such as transient headache or scalp discomfort will be monitored, and any serious adverse events (e.g., seizures) will be immediately reported to the Research Ethics Committee.

This study seeks to determine whether rTMS or iTBS is more effective than sham stimulation in improving emotion regulation, reducing impulsivity, and decreasing self-harm behaviors. It will also explore whether iTBS, with its shorter session duration, provides a comparable or superior therapeutic benefit to conventional rTMS.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Repetitive Transcranial Magnetic StimulationDevice

    Also called rTMS

    rTMS will be delivered at 5 Hz frequency, 1200 pulses per session, at 80-110% of the individual's resting motor threshold (RMT). Stimulation will be applied to the left DLPFC (F3 according to the 10-20 EEG system) using a figure-of-eight coil. Each session includes 18 minutes of active stimulation followed by 3 minutes of sham stimulation on the target site. Sessions are administered 5 days per week for 4 weeks (total 20 sessions).

  • Intermittent Theta-Burst StimulationDevice

    Also called iTBS

    iTBS will be delivered as 50 Hz bursts (three pulses per burst, 5 Hz bursts) at 80-120% of resting motor threshold, totaling 600 pulses per session. Stimulation will be applied over the left DLPFC (F3 site, 10-20 EEG system). Each session includes 3 minutes of active iTBS and 18 minutes of sham stimulation. Sessions are administered 5 days per week for 4 weeks (total 20 sessions).

  • Sham StimulationDevice

    Sham stimulation will be delivered using the same coil orientation and acoustic cues as the active conditions, but with the magnetic field output disabled. Each session includes 18 minutes of sham rTMS and 3 minutes of sham TBS over the left DLPFC (F3 site). Sessions are administered 5 days per week for 4 weeks (total 20 sessions).
