Official title
Efficacy of Personalized iTBS in Real-World Clinical Settings for Alleviating Schizophrenia Symptoms : A Randomized Single-Blind Trial
Overview
This study is designed to determine whether neuronavigation-guided, personalized Intermittent Theta-Burst Stimulation (iTBS) can produce clinically benefits for patients with schizophrenia when delivered in real-world treatment settings. By situating the intervention within real-world treatment settings-without imposing restrictions on concurrent pharmacotherapy-this trial seeks to generate evidence that is both scientifically rigorous and clinically relevant. The main questions it seeks to address are: Does the personalized iTBS target TMS protocol improve clinical symptoms in patients with schizophrenia within real-world treatment settings? What neural circuit changes, as assessed by functional MRI, occur following TMS treatment? Participants will: Undergo personalized,personalized iTBS target treatment daily for 2 weeks. Complete baseline and post-treatment assessments, including clinical symptom scales (PANSS, HAMA, HAMD) and neuropsychological tests (MoCA, DST, VFT, Stroop Test, and AVLT). Have structural and resting-state functional MRI scans before and after treatment. Be monitored for any treatment-related adverse events.
Detailed description
Effective intervention is critical for reducing relapse risk, improving long-term prognosis, and lowering healthcare costs for schizophrenia.The present study therefore aims to assess whether neuronavigation-guided, individualized Intermittent Theta-Burst Stimulation (iTBS) can accelerate symptom improvement in schizophrenia when delivered in real-world clinical settings. By situating the intervention within real-world treatment settings-without imposing restrictions on concurrent pharmacotherapy-this trial seeks to generate evidence that is both scientifically rigorous and clinically relevant. Patients with schizophrenia will be prospectively recruited and received 2 weeks of iTBS treatment.
Before treatment, structural and resting-state functional MRI data wil be collected from each patient. Clinical symptom severity will be assessed using the Positive and Negative Syndrome Scale (PANSS), Hamilton Anxiety Rating Scale (HAMA), and Hamilton Depression Rating Scale (HAMD). For patients experiencing auditory verbal hallucinations, the Auditory Hallucination Rating Scale (AHRS) will be also administered. Additionally, a battery of neuropsychological tests will be conducted, including the Montreal Cognitive Assessment (MoCA), Digit Span Test (DST), Verbal Fluency Test (VFT), Stroop Test, and Chinese Auditory Verbal Learning Test (AVLT).
After completing the 2-week iTBS treatment, clinical symptom severity, treatment-related adverse events wil be reassessed.
Interventions
- Other Neuronavigation-guided individualized iTBS
Participants will receive individualized iTBS for 14 consecutive days in addition to their usual medication regimen. iTBS parameters: 50 Hz bursts every 200 ms (5 Hz), 2s on/8s off, total 600 pulses per session;6 sessions/day (3 in morning, 3 in afternoon, 3600 pulses/day); 100% RMT intensity; Neuronavigation: Brainsight system (Rogue Research, Canada)
Primary outcome measures
- The Positive and Negative Syndrome Scale (PANSS) [Time frame: baseline and week 2 (post-treatment)]
Secondary outcome measures (4)
- Positive and Negative Syndrome Scale (PANSS) subscales [Time frame: baseline and week 2 (post-treatment)]
- Hamilton Anxiety Rating Scale (HAMA) [Time frame: baseline and week 2 (post-treatment)]
- Hamilton Depression Rating Scale (HAMD) [Time frame: baseline and week 2 (post-treatment)]
- Auditory Hallucination Rating Scale (AHRS) [Time frame: baseline and week 2 (post-treatment)]
