Have you ever had one of those rainy days that makes you feel cold, tired, and want to curl up for a nap? You are not alone. Your rainy-day blues are not only real, they are caused by chemical unbalance in the brain as a result of the lack of sunlight. More recently, scientists have discovered that light can be used to improve brain health. It is called Photobiomodulation.
Depression is estimated to affect 300 million people globally. Antidepressant medication is the first-line treatment for depression, but what about people who did not respond to or want to take medication? New research findings suggest light therapy offers new approach to treating depression.
This paper reports the results from the Elated-2 Pilot Trial. The study is comprised of 21 adult MDD patients age 18 to 65, who underwent twice weekly transcranial photobiomodulation (t-BPM) sessions for 8 weeks. The study finds subjects receiving t-PBM with NIR light showed greater improvement than the sham group that did not receive any light therapy.
Current treatments for depression have significant efficacy and side effect burden. This paper provides a comprehensive overview of years of research on a novel, safe approach called transcranial photobiomodulation (t-PBM) as a device-based treatment that is efficacious, well-tolerated and easy to use.
