by A groundbreaking study published in Radiology suggests that low-level light therapy may enhance brain connectivity in individuals who have experienced moderate . The research was led by scientists at Massachusetts General Hospital (MGH).
For years, the therapeutic potential of lights with varying wavelengths has been explored for their role in wound healing. In this study, 38 patients with moderate traumatic brain injuries were given low-level light therapy within 72 hours of their injuries. traumatic brain injuries The therapy was administered through a helmet that emits near-infrared light, allowing the entire brain to be bathed in the light.
Rajiv Gupta, M.D., Ph.D., from the Department of Radiology at MGH, explained, “The skull is quite transparent to near-infrared light. Once the helmet is placed on a patient, their entire brain is exposed to this light.”
To assess the impact of light therapy, the researchers employed functional MRI and focused on the brain’s resting-state functional connectivity – the communication between brain regions that occurs during rest and without engaging in a specific task. They compared MRI results during three recovery phases: the acute phase (within one week after injury), the subacute phase (two to three weeks post-injury), and the late-subacute phase (three months after injury).
The study included 21 patients who did not receive light therapy as a control to minimize bias due to patient characteristics and potential placebo effects.
