Background: Chronic traumatic encephalopathy, diagnosed postmortem (hyperphosphorylated tau), is preceded by traumatic encephalopathy syndrome with worsening cognition and behavior/mood disturbances, over years. Transcranial photobiomodulation (tPBM) may promote improvements by increasing ATP in compromised/stressed cells and increasing local blood, lymphatic vessel vasodilation.
Objective: Aim 1: Examine cognition, behavior/mood changes Post-tPBM.
Approximately 25-30% of veterans deployed to Kuwait, 1990-91, report persistent multi-symptom Gulf War Illness (GWI) likely from neurotoxicant exposures. Photobiomodulation (PBM) in red/near-infrared (NIR) wavelengths is a safe, non-invasive modality shown to help repair hypoxic/stressed cells. Red/NIR wavelengths are absorbed by cytochrome C oxidase in mitochondria, releasing nitric oxide (increasing local vasodilation), and increasing adenosine tri-phosphate production.

This is the first study to report beneficial effects from tLED therapy in stroke, and parallel changes on functional magnetic resonance imaging (fMRI). Six PWA, 2-18 years poststroke, in whom 18 tLED treatments were applied (3 × /week, 6 weeks) using LED cluster heads: 500 mW, red (633 nm) and NIR (870 nm), 22.

Nitric oxide is released from the cells increasing regional blood flow in the brain.

Methods: Two chronic stroke patients with nonfluent aphasia (mild-moderate and severe) each received twenty minutes of rTMS to suppress the right pars triangularis, followed immediately by three hours of mCILT (5 days/week, 2 weeks). (Each patient had received TMS alone, 2-6 years prior.
