What is the purpose of this trial?

This trial tests a new neurofeedback treatment to reduce light sensitivity in Veterans with mild traumatic brain injury (mTBI). The treatment uses the Micro Current Neurofeedback Device, which sends low-intensity electrical pulses to the brain. Researchers aim to determine if this approach is effective and acceptable for those with light sensitivity. Participants must have a history of mTBI, ongoing light sensitivity, and a recent eye exam showing no major vision problems. As an unphased trial, this study offers Veterans the chance to explore a novel treatment option for light sensitivity.

Will I have to stop taking my current medications?

The trial excludes participants who are currently using medications or substances that may severely affect pupillary response or increase photosensitivity, so you may need to stop taking such medications to participate.

What prior data suggests that this neurofeedback device is safe for reducing photosensitivity in Veterans with mTBI?

Research shows that treatments using low-intensity pulse-based transcranial electrical stimulation (LIP-tES) are generally well-tolerated. Studies with similar devices have found that most people do not experience serious side effects. Reports from past studies on microcurrent neurofeedback, a type of LIP-tES, suggest it has been safely used in adults with conditions like depression, anxiety, and PTSD (post-traumatic stress disorder).

This study serves as an early test, meaning it is smaller and lacks a phase designation. However, similar treatments have been used without major problems. Participants in previous trials have mostly reported mild and temporary side effects, if any. Always consult a healthcare provider for personalized advice. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Most treatments for concussion-related light sensitivity involve rest and gradual return to normal activities, sometimes supplemented by pain relievers. However, this new approach, using Micro Current Neurofeedback, is unique because it employs low-frequency pulse-based transcranial electrical stimulation (LIP-tES). This technique aims to directly modulate brain activity, potentially providing faster and more targeted relief from light sensitivity. Researchers are excited about this treatment because it offers a non-invasive method that could adjust neural pathways, which might lead to improved outcomes compared to traditional methods.

What evidence suggests that this neurofeedback device is effective for reducing light sensitivity in mTBI patients?

Research has shown that microcurrent neurofeedback, which uses gentle electrical signals, may help reduce symptoms in people with mild traumatic brain injury (mTBI). One study found that participants experienced up to a 61% reduction in post-concussion symptoms, such as sensitivity to light, after receiving this type of brain stimulation. In this trial, half of the participants will receive the Micro Current Neurofeedback Device using Low-Frequency Pulse-Based Transcranial Electrical Stimulation (LIP-tES) to evaluate its effectiveness in reducing light sensitivity. Other studies suggest that this neurofeedback can also help with symptoms of depression, anxiety, and PTSD (post-traumatic stress disorder). While more research is needed, these early findings are promising for reducing light sensitivity in people who have had a concussion. ^{1 3 4 5 6}

Are You a Good Fit for This Trial?

This trial is for veterans aged 18-65 with a history of mild traumatic brain injury (mTBI) at least 6 months old and symptoms of light sensitivity. They must have had an eye exam in the last year showing good vision, normal eye functions, and no major eye issues. People with certain eye conditions, neurological diseases like Parkinson's or MS, seizures, motor tics, or those on drugs affecting eyesight/photosensitivity can't join.

Inclusion Criteria

I had a mild traumatic brain injury over 6 months ago.

I experience severe reactions to sunlight.

Your last eye exam in the past year showed that you can see really well, your eyes work normally, and there were no problems found in specific eye tests.

Exclusion Criteria

I have had eye problems related to the retina or optic nerve.

I have had a stroke or experience visual neglect.

I have a history of a neurodegenerative disease like Parkinson's or multiple sclerosis.

Interventions

• Micro Current Neurofeedback Device using Low-Frequency Pulse-Based Transcranial Electrical Stimulation

Trial Overview

The study tests a Micro Current Neurofeedback Device using low-frequency electrical stimulation to see if it helps reduce light sensitivity in people with mTBI. Participants will also undergo MRI scans to look for changes in the brain related to this treatment.

How Is the Trial Designed?

Group I: Neurofeedback Experimental Treatment 1 Intervention

Half of the participants will be blindly assigned to receive 12 sessions of LIP-tES intervention over 6 weeks. A subset of these participants will also complete a resting-state MRI scan during the initial session (prior to LIP-tES intervention) and after their final LIP-tES intervention.

Group II: Sham Treatment Placebo Group 1 Intervention

Half of the participants will be blindly assigned to receive 12 sessions of a sham intervention that will mirror all aspects of the LIP-tES intervention except that no neurofeedback pulses will be delivered. A subset of these participants will also complete a resting-state MRI scan at the beginning of the initial session and at the end of the 12th session.

Neurofeedback, a type of biofeedback, shows promise in treating symptoms of traumatic brain injury (TBI) by helping patients learn to control their physiological responses, although more rigorous studies are needed to confirm its efficacy.

Preliminary data from a pilot study suggests that using a commercial neurofeedback device may improve motivation for treatment and reduce symptoms related to attention, mood, and mindfulness in patients with mild-to-moderate TBIs.

Electroencephalogram biofeedback (EBF) is recognized as a clinically effective treatment for ADHD, seizure disorders, anxiety, depression, and traumatic brain injury, meeting the 'Clinical Guidelines' standard set by the American Academy of Child and Adolescent Psychiatry.

Repetitive transcranial magnetic stimulation (rTMS) is also endorsed under 'Clinical Guidelines' for treating bipolar disorder, unipolar disorder, and schizophrenia, indicating its efficacy in managing these mental health conditions.

In a randomized controlled trial involving 21 patients with Tourette syndrome, electrodermal biofeedback training did not show a significant advantage over sham feedback in reducing tic frequency or improving well-being after 4 weeks of treatment.

The study suggests that the short duration of training sessions may have limited the effectiveness of biofeedback, indicating that further research is needed to optimize training schedules for potential benefits in managing tics.
