Most frequently used red and near infrared photobiomodulation therapy treatment parameters on the patients with post-traumatic stress disorder

Abstract

Photobiomodulation therapy (PBMt) has been reported effective for the treatment of post-traumatic stress disorder (PTSD) at low cost in the clinical trial journals for years. PBMt is reported to increase the production of brain-derived neurotrophic factor (BDNF) which promotes the growth and survival of neurons. BDNF is thought to play a role in the regulation of mood, learning, and memory, and it is also thought to be involved in the treatment of PTSD. PBMt is also reported to reduce inflammation in the brain, which is regarded helpful for reducing the symptoms of the psychiatric disorders, including PTSD. In this paper, the PBMt treatment recipes and the results on the PTSDs from the clinical papers already published are analyzed and compared. The most frequently used treatment parameters such as irradiances, wavelengths, doses, and light pulsing frequencies are derived. The treatment recipes for PTSD patients are also suggested.
