Would you pay out-of-pocket for a wellness device not approved by the FDA to treat health?

A University of Utah study suggests that photobiomodulation, using red and near-infrared light, may help reduce brain inflammation. Researchers investigated the therapy as a potential tool for individuals who have experienced repetitive head trauma.

Why it matters

The study offers a new look at managing neurological recovery, though it currently lacks federal approval for brain injury treatment. For many, these devices remain an expensive, out-of-pocket investment not covered by insurance.

A study published in the Journal of Neurotrauma examined photobiomodulation effects on brain inflammation in football players. The research analyzed light-based therapy as a potential intervention, though clinical outcomes remain under investigation.

The players

Rico Petrini

A former football player who sustained 25 concussions and 15,000 sub-concussive hits and advocates for light therapy.

Vielight

A manufacturer of light-based therapy devices currently seeking FDA approval for brain injury treatment.

Lew Lim

A doctor working to secure FDA approval for photobiomodulation devices in neurological applications.

The details

The Vielight device delivers red and near-infrared light through the skull and nasal cavity to reach brain tissue. This process aims to stimulate the release of nitric oxide, which relaxes blood vessels to improve local circulation. Additionally, the therapy is intended to boost energy production and support tissue repair by triggering the release of growth factors.

Health Landscape

This research contributes to the emerging field of photobiomodulation as an alternative approach for chronic brain injury symptoms. It sits alongside ongoing investigations into non-invasive therapies for patients who have historically lacked standard, effective treatment options.

Because the device is currently classified as a general wellness product and costs roughly $2,000, it is not covered by insurance. Patients considering this therapy should have a conversation with a physician about the limitations of current research and the lack of FDA approval.

The takeaway

While light therapy shows potential for reducing brain inflammation, it remains an unapproved, high-cost investment for neurological recovery. Individuals interested in addressing persistent symptoms after head trauma should prioritize discussions with a neurologist rather than pursuing self-directed devices.
