Can Light Therapy become an alternative treatment for Traumatic Brain Injuries?

  • By rgpodadmin

Traumatic brain injuries (TBIs) result from concussive impacts to the head, such as car crashes, contact sports, or dangerous falls. The short and long-term effects of TBIs include reduced cognitive function, worse physical well-being, and increased frequency of negative emotions 2,4,12,14. If left untreated, repeated TBIs can lead to Chronic Traumatic Encephalopathy (CTE), a severe form of brain damage that can cause psychotic episodes, dementia, and early death (2,4,12,14).

TBIs are common in the U.S. — the CDC’s latest reporting shows that 2.8 million Americans suffer from brain injury every year, and about 61,000 Americans died from TBIs in 2019 (2,4,12,14). Researchers believe that regulating inflammation could play a key role in treating TBIs and could be the way to provide relief to the millions of folks that suffer from this type of brain damage (3,5,6,8,9-11).

How does TBI impact cognitive function?

One key biological marker of TBI is excessive brain inflammation, a set of cellular responses to tissue damage or infection (3,8,13). Normally, a small amount of inflammation can help our brain fight off infections and heal from injuries — but with extreme and sudden damage from TBIs, too much inflammation builds up in our brain cells and leads to oxidative stress (3,8,13).

Increased inflammation and oxidative stress can lead to emotional disorders like depression, anxiety, Post-Traumatic Stress Disorder (PTSD), and insomnia (inability to sleep). Chronic brain inflammation is also associated with dementia, Alzheimer’s, and other severe brain diseases (3,8,13).

“Treating TBIs quickly and effectively is of the utmost importance.”

Unfortunately, TBI can be challenging to treat, leaving many folks unable to recover (3,5,6,8,13).

Why is TBI difficult to treat?

Both the brain’s delicacy and the dense skull that encases it make surgery dangerous and expensive (3,8,13). Common medications that reduce inflammation have limited effectiveness within the brain (3,8,13). Alternative treatments that slow down brain activity to reduce inflammation, such as cryotherapy or inducing an artificial coma, can lead to potentially lethal blood clots and dangerously low blood pressure (1,3,8).

“Researchers believe that Light Therapy could be an alternative way to help treat TBI by reducing brain inflammation and increasing cognitive function and overall well-being (5,6,8,9-11).”

How can Light Therapy help treat TBI?

ReGen Pod has compiled some of the studies that show Light Therapy’s potential to treat TBI below:

A 2007 study found that Light Therapy reduced the size of torn and bruised brain areas in animals who suffered from TBI-like injuries (11). These TBI-like injuries caused confusion in the animals and made it difficult for them to balance and move their bodies in a coordinated way (11). The reductions in brain injuries provided by Light Therapy allowed the animals to regain their bodily functions, healing their brain at the cellular level (11).

A 2013 study found that Light Therapy improved recovery from TBIs in humans. The subjects of the study suffered from TBIs due to car crashes, close contact with explosives, or falling incidents (9). Light Therapy Treatment allowed the subjects to think more clearly, feel more energetic and awake, and sleep better compared to not receiving any treatment (9). Researchers believe that these improvements were due to red light penetrating the brain and reducing inflammation while increasing cellular energy production, leading to lasting health benefits (9).

Another study looked at humans with long-term TBI to see if Light Therapy could offer relief (6). The researchers applied Light Therapy to the skulls of the subjects in 20 sessions over two months (6). After these sessions, the researchers measured how the subjects performed on cognitive (memory and word recognition) tasks and emotional surveys (6). The scientists also used brain-scanning technology to measure changes in cellular health and brain function (6). The results indicated that patients benefited from improved quality of life and cognitive function after Light Therapy treatments, reducing depression, anxiety, and insomnia (6). Additionally, the brain scan data showed the subject’s brain function to be healthier than at the beginning of the study, demonstrating that Light Therapy can help treat TBIs at the cellular level (6).
