What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests if special lights can help people with brain injuries by making their brain cells work better. It aims to improve memory, sleep, and overall quality of life. Previous research has shown that using these lights after a brain injury can protect brain cells.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

Is LED therapy safe for humans?

LED therapy, including red and near-infrared light, is generally considered safe for humans. Studies have shown that it is noninvasive, painless, and does not cause serious side effects. Some mild skin reactions like temporary redness or darkening may occur, but no serious adverse events have been reported. ^{1 2 3 4 5}

How does LED therapy differ from other treatments for traumatic brain injury?

LED therapy for traumatic brain injury is unique because it uses red and near-infrared light to improve brain function by enhancing blood flow and cellular energy without being invasive or causing pain. This treatment is non-thermal and can be administered at home, making it different from other more invasive or drug-based therapies. ^{2 3 5 6 7}

What data supports the effectiveness of LED therapy for traumatic brain injury?

Research shows that using red and near-infrared light therapy with LEDs can improve brain function and blood flow in people with chronic traumatic brain injury. Studies have reported better cognitive performance and increased blood flow in the brain after LED treatment. ^{1 2 3 5 8}

Are You a Good Fit for This Trial?

This trial is for English-speaking adults aged 21-55 who have experienced a mild traumatic brain injury (TBI) with loss of consciousness for no more than 30 minutes. It's specifically aimed at active-duty personnel or veterans exposed to blasts. People with penetrating head injuries, previous neurological or psychotic disorders, or significant hearing or vision impairments cannot participate.

Inclusion Criteria

LOC of 30 min or less

Veterans who have had a traumatic brain injury or exposure to blasts during their service in Iraq or Afghanistan.

I am between 21 and 55 years old.

Exclusion Criteria

I have a history of neurological conditions.

You had a mental illness like schizophrenia before a head injury.

I have difficulty with my hearing or vision.

Timeline for a Trial Participant

Published Research Related to This Trial

In a study involving 12 military Veterans with chronic traumatic brain injury (TBI), pulsed transcranial photobiomodulation therapy (PBMT) using LEDs significantly improved neuropsychological scores in 40% of the assessed areas, indicating potential cognitive benefits.

SPECT imaging revealed increased regional cerebral blood flow (rCBF) in 66.7% of participants, suggesting that LED therapy may enhance brain function years after injury, although further research with larger sample sizes is needed.

Pulsed Transcranial Red/Near-Infrared Light Therapy Using Light-Emitting Diodes Improves Cerebral Blood Flow and Cognitive Function in Veterans with Chronic Traumatic Brain Injury: A Case Series. Hipskind, SG., Grover, FL., Fort, TR., et al.[2020]

Transcranial LED treatments showed significant cognitive improvements in two chronic TBI patients, with one patient increasing her sustained attention from 20 minutes to 3 hours after eight weekly sessions.

Both patients experienced notable recovery in cognitive functions and quality of life, suggesting that transcranial LED therapy could be a promising home-based treatment for chronic TBI, warranting further controlled studies.

In two phase I clinical trials involving 115 healthy participants, LED-red light (LED-RL) was found to be safe at fluences up to 320 J/cm2 for skin of color and 480 J/cm2 for non-Hispanic Caucasians, with only mild adverse events reported.

The study identified that dose-limiting adverse events, such as blistering, occurred at higher fluences, indicating that LED-RL may have different effects based on skin type, which is important for guiding future therapeutic applications.

This study is a double-blinded, randomized controlled trial involving 32 patients with diffuse axonal injury from severe traumatic brain injury, testing the effects of transcranial LED therapy on cognitive function and cerebral circulation.

The therapy involves 18 sessions of LED stimulation over 6 weeks, and aims to improve cognitive outcomes and promote beneficial changes in blood flow to the brain, addressing a gap in clinical trials for TBI cognitive rehabilitation.

Transcranial photobiomodulation (tPBM) using red and near-infrared LEDs has shown significant improvements in cognitive function and reduced PTSD symptoms in chronic traumatic brain injury (TBI) patients, based on a study of 11 patients who received 18 treatments over 6 weeks.

The LED therapy is noninvasive and painless, and ongoing studies are exploring its effects on sleep and cognitive function in TBI patients, with promising results indicating increased sleep duration and continued cognitive benefits.
