Multi-target TMS for Schizophrenia Negative Symptoms

26. April 2026 aktualisiert von: 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 left dorsolateral prefrontal cortex (L-DLPFC), left inferior parietal lobule (L-IPL), and right orbitofrontal cortex (R-OFC) for negative symptoms of schizophrenia.

Detaillierte Beschreibung

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 Left Dorsolateral Prefrontal Cortex (L-DLPFC), Left Inferior Parietal Lobe (L-IPL), and Right Orbitofrontal Cortex (R-OFC) for negative symptoms of schizophrenia. MRI-guided neuronavigation will be used to localize targets in each subject. Stimulation will be delivered at 100% of the resting motor threshold (RMT), with a total of 50 Theta Burst Stimulation (TBS) sessions, which include intermittent TBS (iTBS) and continuous TBS (cTBS). In the order of L-DLPFC (iTBS)→ L-IPL (iTBS) → R-OFC (cTBS), each target receives 600 pulses, for a total of 1800 pulses across three targets. Five sessions will be administered 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 TBS treatment.

Primäre Ergebnismessungen

Ergebnis Maßnahme
Maßnahmenbeschreibung
Zeitfenster
Change in severity of negative symptoms before and after TBS intervention, i.e., change in Positive and Negative Syndrome Scale - Negative subscale (PANSS-N)

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 TBS (Day 14), and at 1 week (Day 21), 2 weeks (Day 28), and 4 weeks ( Day 42) after completion of TBS treatment.
