Schizophrenia brain zapping study pulled before starting
NCT ID NCT03729791
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study planned to use a gentle brain stimulation technique called tDCS to see if it could help people with schizophrenia who have negative symptoms (like lack of motivation or emotion). Researchers wanted to use brain scans to understand how it works. However, the study was withdrawn before any participants were enrolled, so no results are available.
