Подробное описание
Major depressive disorder (MDD) is a highly prevalent and disabling psychiatric disorder. A substantial proportion of patients do not achieve sufficient improvement with conventional antidepressant treatments, resulting in treatment-resistant or difficult-to-treat depression. Noninvasive neuromodulation approaches such as transcranial magnetic stimulation (TMS) have emerged as effective alternatives for these patients. Accelerated intermittent theta burst stimulation (iTBS), delivered in multiple daily sessions over a short period, may provide faster clinical improvement compared with conventional protocols.
This prospective single-arm interventional study aims to evaluate the clinical efficacy and biological correlates of accelerated bilateral dorsomedial prefrontal cortex (DMPFC) iTBS in adults with MDD who have shown inadequate response to at least one adequate antidepressant treatment trial.
Participants aged 18 to 65 years will receive accelerated bilateral DMPFC iTBS for five consecutive days, with four sessions per day (20 total sessions). Participants demonstrating partial clinical improvement without remission after 20 sessions may receive an additional 10 sessions according to clinical evaluation.
Clinical assessments will be performed at baseline, during treatment, at the end of treatment, and at one-month follow-up. Outcome measures include Hamilton Depression Rating Scale (HAM-D), Beck Depression Inventory, Beck Anxiety Inventory, suicidal ideation measures, self-rated depressive symptom scales, and Clinical Global Impression ratings.
Blood samples will be collected at baseline and after treatment to evaluate neurobiological biomarkers, including cortisol, adrenocorticotropic hormone (ACTH), brain-derived neurotrophic factor (BDNF), interleukin-1 beta (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), and C-reactive protein (CRP).
The primary objective is to determine treatment response based on reduction in depressive symptom severity. Secondary objectives are to examine biomarker changes associated with treatment, identify predictors of response, and explore the relationship between early symptom improvement and final clinical outcomes.

Экспериментальный: Accelerated iTBS
Participants receive accelerated bilateral dorsomedial prefrontal cortex intermittent theta burst stimulation (iTBS) administered over five consecutive days, with four sessions per day (20 sessions total).
Participants with partial clinical response may receive an additional 10 sessions.
|
Accelerated intermittent theta burst stimulation (iTBS) is administered bilaterally to the dorsomedial prefrontal cortex using a double-cone coil, targeting the stimulation site based on anatomical landmarks.
Treatment is delivered over five consecutive days with four sessions per day (total of 20 sessions).
Each session consists of 600 pulses per hemisphere (1200 pulses total) at an intensity of 120% of the individual motor threshold.
Participants with partial response may receive an additional 10 sessions.
