Summary
This review examines how different wavelengths of light—particularly blue light for alerting and circadian effects, and red/green light for other therapeutic properties—could be leveraged as adjunctive treatments for patients recovering from mild traumatic brain injury. The authors recommend a personalized medicine approach to light therapy targeting sleep, cognition, and mood deficits common in mTBI recovery.
Key Findings
- Blue-wavelength light has the strongest evidence for alerting, cognitive enhancement, and circadian phase-shifting properties relevant to mTBI recovery.
- Red and green wavelengths may offer complementary therapeutic effects, though the mechanisms and clinical applications require further research.
- Authors conclude that light therapy is a promising but under-researched adjunctive treatment for mTBI, and advocate for individualized protocols based on patient circadian and symptom profiles.
