Zapping the brain to sharpen the mind in schizophrenia
NCT ID NCT06155682
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a type of brain stimulation called repetitive TMS can increase natural brain inhibition in 34 people with schizophrenia. The goal is to see if this change relates to better thinking and memory. Participants will receive five days of treatment and undergo brain scans and cognitive tests.

Inclusion Criteria: 1. Age 18-45 years 2. Male or Female 3. Able to participate in the informed consent process and provide voluntary informed consent. 4. A Diagnostic and Statistical Manual of Mental Disorders 5 (DSM-5) diagnosis of schizophrenia documented by the Structured Clinical Interview for DSM-5 (SCID-5) Exclusion Criteria: 1. A history of a DSM-5 substance misuse disorder (other than caffeine or tobacco or mild marijuana misuse) within the past six months; or a positive baseline urine drug screen. 2. A history of a current neurological disorder (including, but not limited to Parkinson's Disease, epilepsy, or Multiple Sclerosis) 3. History of head trauma resulting in unconsciousness 4. Contraindications for TMS, including any history of seizure other than febrile seizure, presence of ferromagnetic metal in cranium, presence of cochlear implant, presence of deep brain stimulation (DBS) electrodes based on medical history 5. Contraindications for MRI, including pacemakers or other metal in body 6. Suspected DSM-5 intellectual disability based upon clinical interview and psychosocial history 7. Pregnancy 8. Any change in type of antipsychotic medication in the last 30 days and dose in the last 14 days 9. Treatment with a benzodiazepine with a dose equivalent to lorazepam 2 mg/day or greater or any anticonvulsant due to the potential of these medications to affect TMS SICI score and the efficacy of rTMS 10. Prior history of treatment TMS (equivalent to 5 or more sessions of rTMS or theta-burst) in the past 6 months 11. Endorsement of active suicidal ideation on the Columbia-Suicide Severity Rating Scale (version: last 30 days) reflected by "yes" response on items 3, 4, or 5 of the ideation questions and/or "yes" to any of the four suicidal behavior items (actual attempt, interrupted attempt, aborted attempt, preparatory acts/behavior) 12.
