简要总结
Advances in repetitive transcranial magnetic stimulation (rTMS) protocols with intermittent theta-burst stimulation (iTBS) have significantly decreased the duration for one single session and thereby enabled accelerated treatment plans with multiple sessions per day, potentially reducing the total treatment duration. This randomized, placebo-controlled study investigates the effects of accelerated iTBS treatment with connectivity-informed neuronavigation on symptom severity, sleep, interoception, and cognitive control in patients with major depressive disorder and with or without comorbid borderline personality disorder using magnetic resonance imaging (MRI).
详细描述
Repetitive transcranial magnetic stimulation (rTMS) is a safe and efficacious treatment option for treatment-resistant depression. Advances in rTMS protocols with intermittent theta-burst stimulation (iTBS) have significantly decreased the duration for one single session and thereby enabled accelerated treatment plans with multiple sessions per day, potentially reducing the total treatment duration. Major depressive disorder (MDD) is characterized by impairments in various domains including sleep, impulse control, and interoception. Borderline personality disorder (BPD) is characterized by fear of abandonment, mood swings, and an unstable perception of self and often occurs with comorbid MDD. This comorbidity frequently impedes treatment of the BPD.
In this randomized, placebo-controlled study, 60 patients with treatment-resistant MDD (30 verum group, 30 sham group) and 60 patients with treatment-resistant MDD and comorbid BPD (30 verum group, 30 sham group) will receive two weeks of connectivity-informed iTBS of the left dorsolateral prefrontal cortex (DLPFC; 3 sessions per day, 5 days per week). Before and after the treatment phase, (functional) magnetic resonance imaging (fMRI) will be performed. The effects of iTBS will be tested in four domains: (1) symptom severity (MDD and BPD symptoms), (2) sleep quality (sleep questionnaires and various sleep parameters monitored via an electroencephalography (EEG) headband), (3) neurocognitive effects (vigilance and response inhibition measured with behavioral and fMRI tasks), and (4) interoception (interoceptive attention measured with behavioral and fMRI tasks). Furthermore, before the start of the two-weeks treatment, a single iTBS session ("forecaster session") will be conducted to explore the validity of early symptom/mood responses and hormonal changes for the prediction of the the treatment outcome. Treatment effects will be analyzed within and across patient groups (MDD and MDD + BPD). In addition, domain-specific treatment effects will be analyzed as a function of distinct iTBS targets within the DLPFC.To evaluate pathological biases, the investigators will compare the patients' data with a control group of 30 healthy participants who will also be tested twice (without iTBS).

结局指标
主要结局
Change in depression severity after the treatment phase
时间窗: Up to 5 weekdays after the last iTBS treatment session
Measured with the Montgomery Asberg Rating Scale (MARDS). Remission defined as MADRS score (range: 0 to 60) of less than or equal to 10. Response defined as a reduction of at least 50 percent from baseline in MADRS score.
Changes in behavioral responses in an interoception task before the first and after the last treatment session
时间窗: Up to 5 weekdays before the first and after the last treatment session
Measured as performance in an interoception task during fMRI
Changes in neural responses in a cognitive control task before the first and after the last treatment session
时间窗: Up to 5 weekdays before the first and after the last treatment session
Measured with functional magnetic resonance imaging (fMRI) while performing a cognitive control task
Change in BPD severity after the treatment phase
时间窗: Up to 5 weekdays after the last iTBS treatment session
Measured by the Zanarini rating scale for BPD (Zan-BPD, range 0-36). Remission is defined as score of 9 or less. Response defined as a decrease from baseline in Zan-BPD score of at least 20 percent of the scoring range, i.e. a reduction of 8 points or more.
