What this study is about

View original scientific description
The proposed study will evaluate a new approach to cognitive rehabilitation of mTBI using a brain stimulation technique called "Remotely Supervised Transcranial Direct Current Stimulation combined with Cognitive Training" (RS-tDCS+) which has shown promise for improving complex attention in both healthy and clinical populations. RS-tDCS+ is a home-based, low-risk, non-invasive technique that is designed to boost cognitive training by enhancing learning and the brain's ability to reorganize connections. This study will evaluate RS-tDCS+ for improving complex attention in Active Duty Service Members (ADSM) and Veterans with a history of mTBI. Different tests of complex attention and symptom questionnaires will be used to determine the effects of real versus sham (placebo) RS-tDCS+. Second, the investigators will investigate electrical and connectivity changes in the brain associated with RS-tDCS+ using electroencephalogram (EEG) and magnetic resonance imaging (MRI). Third, the investigators will investigate the lasting effects of any observed changes by evaluating participants at 1 and 6 weeks post-treatment. Lastly, the investigators will explore the impact of individual differences (e.g., PTSD, depression, sleep quality, time since injury, baseline impairment, age, sex, ADSM versus Veteran) on treatment outcome.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Active-Duty Service Members.
- Ages 18 to 60.
- All genders.
- All racial and ethnic groups.
- History of mild TBI (as defined by the DOD/VA criteria used in conjunction with the OSU TBI-ID) sustained at least 3 months and no more than 10 years prior to enrollment.
- Self-reported attention and/or concentration difficulties.
- At least one cognitive symptom reported on the Neurobehavioral Symptom Inventory (NSI) cognitive subscale.
Exclusion criteria
- Presence of a medical, psychiatric, physical or non-physical disease, disorder, condition, injury, disability or pre-existent history such that study participation, in the opinion of the PI: (a) may pose a significant risk to the participant; (b) raises the possibility that the participant is unlikely to successfully complete all of the requirements of the study according to the study protocol; or (c) might adversely impact the integrity of the data or the validity of the study results. Specific conditions include (but are not limited to) a history of: brain tumor, epilepsy, cerebral vascular accident (CVA), Schizophrenia, Bipolar Disorder, and Mania.
- History of prior treatment with ECT or neuromodulation in the last 12 months.
- Current, diagnosed substance dependence.
- Newly prescribed medication within the previous 3 weeks.
- Diagnosis of intellectual disability or pervasive developmental disorder (i.e., premorbid IQ less than or equal to 70).
- Any medical condition or treatment other than mild TBI (e.g., stroke, tumor, HIV, moderate-severe TBI), with significant neurological disorder or insults that, based on the Principal Investigator's judgment, would impact risk.
- Psychosis or mania within 30 days of enrollment, as determined by the PI, based on a psychiatric history and examination and/or a review of available medical records
- Contraindications for tDCS (e.g., metallic cranial plates/screws or implanted device, eczema or skin lesions on scalp)
- A positive pregnancy report.
Where
- San Diego, California
- Minneapolis, Minnesota
Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
