“We examined the use of near-infrared and red radiation (photobiomodulation, PBM) for treating major depressive disorder (MDD). … Research has demonstrated a correlation between MDD and vulnerability to oxidative stress. … Oxidative stress may be an effective target for antidepressant treatments.” (NIH)
“In addition, we used PubMed to find articles that examine the link between PBM and relevant biological processes including metabolism, inflammation, oxidative stress, and neurogenesis. Studies suggest the processes aforementioned are potentially effective targets for PBM to treat depression.” (NIH)
“One of the two cases with chronic TBI [traumatic brain injury] reported by Naeser et al. was a 52-year-old veteran with comorbid PTSD. After few months of treatment with transcranial PBM, she noticed improvement in self-awareness and self-regulation in both social and work milieus. These benefits were attributed to improved sleep and reduced impulsivity, irritation and anger, consistent with common PTSD symptoms. After 4 months of treatment her medical disability was discontinued and she returned to her prior work.” (NIH)
