tACS to help tell self from others in schizophrenia
Official title: Transcranial Alternating Current Stimulation (tACS) at 10 Hz Targeting Medial Prefrontal Cortex for Improving Self-Other Differentiation in Patients With Schizophrenia: A Randomized, Double-Blind, Sham-Controlled Trial
Run by Anhui Medical University · NCT07818668 · Data updated 2026-11-12
A non-invasive brain stimulation method (tACS) is tested to see if it helps people with schizophrenia better distinguish themselves from others.

Is this trial a fit for you?
✓Likely a good fit
Adults 18-50 with a DSM-5 diagnosis of schizophrenia and current hallucinations or delusions, medically stable on antipsychotic meds for at least 4 weeks.
✕Probably not a fit
Individuals without schizophrenia or those not meeting stability criteria may not experience benefit.

What this trial studies
This study uses transcranial alternating current stimulation (tACS) targeting the medial prefrontal cortex to see if it improves self-other boundary processing in schizophrenia. Participants include patients with schizophrenia, people with high schizotypal traits, and healthy controls, to explore underlying mechanisms through behavioral tasks and brain activity. The protocol involves 10 Hz stimulation at 2 mA for 20 minutes daily over five days, with a sham control for comparison. Two computer-based face-recognition tasks manipulate prior probability and perceptual uncertainty to probe self-other processing.
Why it matters
Potential benefit: If successful, this approach could improve social cognition and self-awareness in schizophrenia.
How similar studies have gone: Similar non-invasive brain stimulation approaches have shown mixed results; this study explores a targeted mechanism with a novel design.
