Photobiomodulation (PBM) is a non-invasive technique that uses low-level light therapy (LLLT) to improve cellular function and promote healing. While it has been widely used in medical applications, recent studies have explored its potential in enhancing cognitive performance. The United States Food and Drug Administration (FDA) has conducted extensive research to evaluate the safety and efficacy of PBM in this context. This article will provide an overview of the FDA findings on whether photobiomodulation can enhance cognitive performance.
Evidence-based Research on Photobiomodulation
In several controlled studies, PBM has shown promising results in enhancing cognitive function. The FDA research highlights the following key findings:
1. Improved Memory
PBM has been found to enhance memory performance, particularly in tasks related to learning and recall. Several regions of the brain associated with memory formation and retrieval show increased activity following PBM.
2. Increased Attention and Focus
Studies have demonstrated that PBM can significantly improve attention and focus, leading to increased cognitive performance. The therapy stimulates neuronal activity in the prefrontal cortex, the area responsible for executive functions.
3. Enhanced Mental Processing Speed
PBM has been shown to improve mental processing speed, allowing individuals to respond faster to stimuli. This effect is attributed to increased ATP production and improved neuronal connectivity.
4. Reduced Mental Fatigue
PBM has the potential to reduce mental fatigue and improve cognitive endurance. The therapy has been found to decrease levels of oxidative stress and promote cellular energy production in the brain.
5. Potential Neuroprotective Effects
Research suggests that PBM may have neuroprotective effects, potentially preventing or slowing down cognitive decline associated with aging. This finding opens up avenues for further investigation into the long-term benefits of PBM.
Comparison of PBM Costs in Different Countries
The cost of PBM treatment can vary depending on the country. Here is a comparison of average PBM costs in the United States, United Kingdom, South Korea, Japan, and China:
1. United States:
Average PBM session cost: $100-$200
2. United Kingdom:

Frequently Asked Questions
1. Is photobiomodulation safe?
Yes, photobiomodulation is considered a safe therapy with minimal risks or side effects. However, it is recommended to consult with a healthcare professional before undergoing PBM treatment.
2. How many PBM sessions are required to see results?
The number of PBM sessions required may vary based on individual needs and goals. Typically, a series of sessions is recommended for optimal results, ranging from 6 to 12 sessions, spread over several weeks.
3. Can PBM be used in conjunction with other cognitive enhancement techniques?
Yes, PBM can be combined with other cognitive enhancement techniques such as meditation, exercise, and brain-training exercises to maximize overall cognitive performance.
4. Does insurance cover PBM treatment?
Insurance coverage for PBM treatment varies and may depend on the specific insurance policy. It is advisable to contact the insurance provider for detailed information regarding coverage.
5. Can anyone undergo PBM therapy?
Prior to undergoing PBM therapy, it is recommended to consult with a healthcare professional. Individuals with certain medical conditions or those taking specific medications may need to exercise caution or avoid PBM treatment.
