Multi-target TMS for Schizophrenia Negative Symptoms

2026年9月6日 更新者:Shanghai Mental Health Center

Development of a Multi-target Transcranial Magnetic Intervention Technique for Negative Symptoms of Schizophrenia

This randomized controlled trial (RCT) is the first to evaluate the efficacy and safety of a multi-target TMS protocol targeting the right orbitofrontal cortex (R-OFC), left dorsolateral prefrontal cortex (L-DLPFC), and left inferior parietal lobule (L-IPL) for negative symptoms of schizophrenia.

詳細な説明

Schizophrenia is a chronic and severe mental disorder. Although antipsychotic medications are effective for positive symptoms, they offer limited improvement for negative symptoms and cognitive deficits. Effective treatments for these symptoms are still lacking. To address current clinical bottlenecks, there is an urgent need to develop novel, effective treatment strategies. Repetitive transcranial magnetic stimulation (rTMS) is a recently developed neuromodulation technique. The latest evidence-based guidelines indicate that the level of evidence for rTMS in treating schizophrenia remains low (i.e., Level C evidence, possibly effective). However, the critical parameter of target selection has not received sufficient attention. This randomized controlled trial (RCT) is the first to evaluate the efficacy and safety of a multi-target TMS protocol targeting the Right Orbitofrontal Cortex (R-OFC), Left Dorsolateral Prefrontal Cortex (L-DLPFC), and Left Inferior Parietal Lobe (L-IPL) for negative symptoms of schizophrenia. MRI-guided neuronavigation will be used to localize targets in each subject. The intensity of TMS stimulations is set to 80-120% of resting motor threshold (RMT). A total of 50 TMS sessions will be administered. The stimulation sequence will be R-OFC (1 Hz) → L-DLPFC (iTBS) → L-IPL (iTBS). The first target (R-OFC) will receive 720 pulses at 1 Hz, while the second and third targets (L-DLPFC and L-IPL) will each receive 900 pulses of iTBS. Five sessions will be delivered per day for 10 consecutive working days, with a 60-minute interval between sessions. Clinical assessments, cognitive evaluations, and resting-state functional Magnetic Resonance Imaging (MRI) scans will be performed before and after TMS treatment.

メジャーの説明
時間枠
Change in severity of negative symptoms before and after TMS intervention, i.e., change in Positive and Negative Syndrome Scale - Negative subscale (PANSS-N)
時間枠:Negative symptoms will be measured at baseline (Day-4±2), immediately after the 50th session of TMS (Day 14), and at 2 weeks (Day 28), and 4 weeks ( Day 42) after completion of TMS treatment.

Schizophrenia negative symptoms assessed using Positive and Negative Syndrome Scale - Negative subscale (PANSS-N)

Minimum value: 7 (each of the 7 items scored 1 = absent)

Maximum value: 49 (each of the 7 items scored 7 = extreme)

Higher score indicates: Worse outcome (greater severity of negative symptoms)

Negative symptoms will be measured at baseline (Day-4±2), immediately after the 50th session of TMS (Day 14), and at 2 weeks (Day 28), and 4 weeks ( Day 42) after completion of TMS treatment.
