Frontal Gamma Coherence Neurofeedback for Patients With Schizophrenia
17 de junio de 2026 actualizado por: BioSignal Solutions LLC
Preliminary Placebo-Controlled Double-Blind Randomized Clinical Trial of Mobile Platform to Improve Memory From Home or Office for Patients With Schizophrenia
This preliminary, randomized, double-blind, placebo-controlled clinical trial will evaluate frontal gamma coherence neurofeedback in adults with schizophrenia.
Thirty participants will be randomly assigned to receive either active neurofeedback or placebo neurofeedback using a study-provided mobile platform.
Participants will complete baseline assessments in person at the University of California San Diego, receive training on home use of the neurofeedback platform, and complete twice-weekly 30-minute sessions at home for 12 weeks.
Participants will return for midpoint and end-of-treatment assessments to evaluate feasibility, tolerability, cognitive outcomes, and neurophysiological target engagement.

Descripción detallada
In this preliminary placebo-controlled, double-blind randomized clinical trial (RCT), eligible participants will be randomized (block permutation) to either Active frontal coherence gamma neurofeedback (gcoh-NFB, n = 15) or Placebo neurofeedback (placebo-NFB, n = 15).
All participants will present in person to Univ. of Ca.
San Diego (UCSD) for Baseline assessments of primary and secondary outcome measures, and will receive training on self-administration of gcoh-NFB from home.
All participants will be provided with mobile treatment platform, with instructions to practice gcoh-NFB from home twice weekly (30 minutes per session) for 12 weeks (24 sessions total).
Study personnel will reach out to patient by phone and video at least weekly to facilitate gcoh-NFB self administration.
Staff will be available by phone and video more frequently, as indicated by participant performance or preference.
All participants will return to UCSD for midpoint (Week 6, or after 12 sessions) and end-of-treatment (Week 12, or after 24 session) in person assessments of primary and secondary outcome measures, and maintenance or return of mobile treatment platform.
For participants randomized to Active gcoh-NFB, mobile treatment platform presents reinforcement signals coupled in real time to target neurobiological features.
For participants randomized to Placebo-NFB, mobile treatment platform presents reinforcement signals recorded previously during active gcoh-NFB sessions from other participants.

Comparador activo: Active frontal gamma coherence neurofeedback
|
Frontal gamma coherence neurofeedback (gcoh-NFB) uses electroencephalographic (EEG) to reward active maintenance of gamma coherence recorded at frontal F3 and F4 electrode sites (from the International 10-20 System for EEG electrode placement).
|
|
Comparador de placebos: Placebo neurofeedback
|
For participants randomized to Placebo-NFB, mobile treatment platform presents reinforcement signals recorded previously during active gcoh-NFB sessions from other participants

Descripción del plan IPD
Individual participant data will not be made publicly available.
Because this SBIR-funded project involves translation of a proprietary EEG neurofeedback platform, the scientific data, device-use data, analytic outputs, and platform-related data are expected to include proprietary SBIR/STTR data.
BioSignal Solutions LLC will preserve final research datasets and associated documentation internally to support NIH reporting, human-subjects oversight, regulatory development, intellectual-property protection, and scientific publications, as applicable.
Aggregate findings may be disseminated through NIH reports, presentations, regulatory communications, and peer-reviewed publications.
Any case-by-case sharing of data underlying a publication would be considered only if consistent with SBIR/STTR data rights, intellectual-property strategy, privacy protections, informed consent, IRB determinations, contractual obligations, applicable laws, and award terms.
