## Breakthrough in Brain Injury Treatment

Researchers at the University of Utah are studying itPBM, a medical-grade red-light therapy showing promising results in reducing brain inflammation and improving cognitive functions. The treatment, called photobiomodulation therapy, differs from superficial red-light applications seen in skincare. Initial studies suggest it could safeguard neurological health without reducing physical activity, particularly beneficial for athletes with repeated head impacts.

## Former Athlete's Personal Journey

Larry Carr, a former BYU football star and adjunct professor, credits itPBM with helping him recover from years of brain damage. His 2013 diagnosis led him to collaborate with researchers, compiling what co-director Elisabeth Wilde calls 'striking' research. Carr's personal experience adds a compelling human element to the scientific findings, demonstrating potential real-world applications beyond laboratory settings.

## Groundbreaking Football Player Study

A 2021 study of 26 BYU football players revealed significant differences between treated and untreated groups. Untreated players developed widespread brain inflammation, while the itPBM group showed no comparable increase and even demonstrated reduced inflammation in some regions. Researcher Michael Carr noted this marked the first time players' brains appeared healthier after a season than before.

## Cognitive and Emotional Improvements

Treated participants showed fewer symptoms of depression, anxiety, stress and PTSD. They also demonstrated faster processing speeds, better sustained attention, and stronger executive function. These cognitive improvements were accompanied by enhanced balance, motor control and grip strength, suggesting comprehensive neurological benefits from the therapy.

## Peer-Reviewed Evidence Base

Fourteen peer-reviewed studies have linked itPBM with various neurological improvements. Brain imaging has consistently shown reduced inflammation and improved connectivity. The treatment's effects extend beyond athletes to men and women from various walks of life, indicating broad potential applications for different types of brain injuries and conditions.

## Scientific Cautious Optimism

While researchers call the findings promising, they emphasize this isn't a cure-all. Definitive clinical trials haven't been conducted yet, and some in the field remain skeptical. The University of Utah team acknowledges the need for broader research and validation, with some colleagues suggesting the results might be 'too good to be true.'

## Potential Neuroprotective Mechanism

The therapy appears to work by delivering specific wavelengths of light to brain tissue, stimulating cellular repair processes. This photobiomodulation may enhance mitochondrial function, reduce oxidative stress, and promote neurogenesis. The intranasal delivery method allows light to reach deeper brain structures than surface applications could achieve.

## Future of Brain Injury Treatment

The University of Utah's research opens new possibilities for treating traumatic brain injuries and concussions. If further validated, itPBM could revolutionize neurological care by offering a non-invasive, drug-free treatment option. The findings justify expanded research into light therapy's potential to protect and repair damaged neural pathways across various conditions.
