Brain injuries are a complex and often overlooked topic, especially when the trauma doesn't seem that serious. But the silent damage can worsen over time, especially because of the inflammatory processes that are activated after the accident.
The University of Birmingham has brought to light a new treatment possibility that promises to innovate the field of neurological rehabilitation: the infrared light therapy. This technology, which is very “Star Trek: Voyager,” is proving to be one of the most effective solutions for dealing with the consequences of brain injuries.
Infrared light beam against inflammation and brain lesions
The discovery made by the research team, led by Professor Zubair Ahmed, represents a real breakthrough in the treatment of brain injuries. Short daily sessions of infrared light, applied directly to the skull, have shown a significant impact on reducing brain inflammation.
It seems almost unbelievable, but the data speak clearly: the cells responsible for inflammation are activated less, and tissue regeneration benefits. And that's not all: The optimal wavelength of light, 810nm, appears to be the one that produces the best results on brain lesions.
The brain repairs itself, aided by technology
How does this therapy actually work? Infrared light penetrates the skull and stimulates the photobiomodulation: a process that reduces cellular damage, including programmed cell death (apoptosis), and promotes healing.
It's as if the brain received external help to speed up its repair mechanisms from brain injuries, and without invasive side effects. In a study conducted on animal models (I link it here), Ahmed's team demonstrated that, after four weeks, subjects treated with infrared light showed significant improvements in cognitive and motor skills, compared to control groups.
A future made of light
There is something incredibly fascinating about the idea that a technology as simple as infrared light could have such a profound impact on our bodies, and especially our brains. And yet, it is only the beginning.
Researchers are now working to develop a medical device that can apply this therapy practically and effectively to patients, starting with tests on larger mammals and then refining everything with trials on human patients. Let's hope that the future of brain injury recovery could be much brighter.literally.
